The rite of inhumation burials underneath barrows gave way to cremation of the deceased. Their remains were collected in urns and buried in large cemeteries, called urnfields. Besides the shift from inhumation to cremation this urnfield phenomenon included a new type of fine pottery, a dominance of central European metalwork types as grave gifts, and the use of sun symbols and bird heads on bronze vessels and armour (Champion et al. 1984, 270). When archaeologists give an overview of Late Bronze Age burial rites in Europe, the urnfield phenomenon is often characterised in a typical way. First, the change in burial ritual is seen to herald a significant transformation in cosmology, even a pan-European spiritual “revolution” in culture and religion (Harding 1994, 318-25). Secondly, as a marked reorientation in spiritual life in large parts of Europe, urnfields are thought to represent a new era of “cultural homogeneity” and “uniformity of beliefs” across the continent (Champion et al. 1984, 270; Cunliffe 2008, 234-5; Harding 2000, 113). And lastly, the emergence of the urnfield burial rite is explained as the rapid spread of central values through elite interaction networks: a precocious manifestation of European globalization (Cunliffe 2008, 267; Kristiansen 1998). But there are reasons to doubt these characterisations. To start, are urnfields really a ‘uniform phenomenon’ with a single meaning? In Central Europe a distinct social differentiation seems to be expressed at cemeteries by the apparent contrast between rich tumuli graves and poor flat-grave cemeteries (Kristiansen 1998, 113). While in other areas of Europe urnfields lack indications for clear social distinctions, although rich metal depositions in watery contexts show that a social hierarchy did exist (Fontijn 2008). This implies that the social meaning of urnfields varied across the continent. Also, the notion of urnfields as a spiritual “revolution” can be doubted. Regional studies demonstrate that the moment and manner of introduction of the phenomenon varied between regions. The fact that there are regions where cremation and urnfield-like cemeteries were already dominant before the rise of urnfields (e.g. Verwers 1971), even leads us to question whether there really was a “revolution”. Lastly, the ideas about elite interaction networks are probably a bit too one-sided. As these are mainly based on the spread of prestigious items across Europe, the focus might be too much on large-scale, inter-regional exchange systems. Urnfields, on the other hand, show distinct local variations, for instance in monument forms, urn types and the kinds of metal burial gifts (Gedl 1991). This indicates that intra-regional and local interaction networks may have played an important part in the spread of burial customs. So it appears that fundamental ideas about the nature and spread of urnfields are in need of rethinking. Being an emblematic element of Late Bronze Age Europe, urnfields obviously are an 7 important object of study. Studying the genesis of urnfields is an imperative exercise. As an alternative to prestigious exchange items, they can give a distinct look into the workings of a Europe that is starting to become ever more integrated culturally, politically and economically – a process that will become to characterize the first millennium BC. As such, a process like the spread of urnfields touches upon themes that are significant even for modern societies, such as culture change, cultural identity and globalization. Obviously, a new approach is needed to study the genesis and spread of urnfields. Local variations in the moment of adoption, material characteristics and meaning of urnfields indicate that a regional focus is needed, rather than solely explanations on a pan-European scale. The southern Netherlands provide an excellent opportunity to adopt such a regional approach. Firstly, because a recently developed method for dating cremated bone has provided new dates for the inception of the phenomenon in this region (Lanting & Van der Plicht 2003; De Mulder et al. 2007). Secondly, because the area contains a large sample of fully excavated, well-published urnfields which has been extended the last twenty years with several large-scale excavations (e.g. Theuws & Roymans 1999). Lastly, because recent studies have significantly enhanced our understanding of the social and cultural context of the urnfield phenomenon in the region (Fontijn 2002; Gerritsen 2001). 1.2 Case Study: The Southern Netherlands The southern Netherlands are part of the Pleistocene cover sand plateau between the rivers Meuse, Demer and Scheldt (fig. 1.1). This area is not only uniform in geological terms, differing from surrounding areas, but also in cultural terms. The beginning of the Urnfield period in this region is dated to the course of the 11th millennium BC (Van den Broeke 1991, 193-4), concurring with the start of the Late Bronze Age. Several models have been put forward to explain the genesis of urnfields in the Meuse-Demer-Scheldt area as an outcome of internal processes (Fokkens 1997; Gerritsen 2001, 251-6). However, each of these models contains several practical and theoretical flaws. Roymans and Kortlang (1999, 36-42) have put forward the hypothesis that changes witnessed in burial rites are the expression of the way society copes with problems resulting from continued demographic expansion and growing pressure on land. They explain that in a period in which the control over land, rather than over labour, was vital to the reproduction of local domestic groups, urnfields served as territorial markers. These burial grounds symbolised the transcendental claim of a local community and its ancestors on a certain territory. Strength of this model is that in contrast to the European-scale models, it does not need the control of elites over surplus, for which there is no empirical support in the Meuse-Demer-Scheldt region (Gerritsen 2001, 252). However, there is equally limited empirical support for population pressure before and during the Late Bronze Age. Evidence for a powerful demographic expansion dates from the Early Iron Age – several centuries after the appearance of urnfields (Gerritsen 2001, 253; Fontijn & Fokkens 2008, 359). Also, it remains implicit in the model why populations rose to a level causing social problems and how population 8 pressure led to the adoption of a different mortuary ritual. The different manners in which this could have taken place (group selection, individuals responding to environmental cues, etc.) can have major consequences for the pace and form of culture change.

(Gerritsen 2001, fig. 2.1) From a different theoretical perspective, Fokkens (1997) explains the appearance of urnfields as part of wider process of social and ideological change. Reviewing evidence from a broad social and cultural context, i.e. burial rites, settlements, bronze exchange and hoarding, he characterizes the transitional period from the Middle to Late Bronze Age as a period of social fragmentation. The extended family groups prevalent in the Middle Bronze Age dissolved into nuclear families. With this new social structure a new ideology came about, stressing individuality. This new notion of the person is expressed in urnfields by all people being entitled to a single grave. In contrast to the European- 9 scale models and the model of Roymans and Kortlang social and cultural changes do not need an external kick, such as an ecological or economic crisis, in the model of Fokkens. By stressing the importance of a social and ideological transformation in explaining culture change Fokkens makes a valuable contribution to the debate about the genesis of urnfields. However, as he points out himself, many questions are left unanswered (Fokkens 1997, 371). Most important, to my opinion, how and why did a change in values lead to the adoption of new beliefs and practices in burial ritual? Recently a new model for the genesis of urnfields has been developed by Fokke Gerritsen (2001, 251-6). On the same token as Fokkens, Gerritsen explains the appearance of urnfields as an expression of social and ideological change. However, rather than individuality, Gerritsen stresses the aspect of communality as expressed in the collective urnfields. Adopting a dwelling perspective, he explains that the appearance of fixed burial grounds and stable local communities at the beginning of the Late Bronze Age is to be understood as the effect of a progressing mythical ordering of the landscape from the Late Neolithic onwards and the decreasing residential mobility with which this was accompanied. As social groups became more closely associated with particular parts of the landscape, urnfields came to be the focus of identification and memory of the local community. Thus an historical relationship was created between a community, its territory and its ancestors. This model is interesting because it incorporates long-term processes and mentalités, rather than only the developments directly before and after the transition from Middle to Late Bronze Age. However, Gerritsen leaves it unclear how local communities become associated with particular parts of the landscape through increasing interaction with its historical dimensions. Little empirical evidence is used to explore the spatial and ideological relationship between people and historical, mythical places in the landscape. In fact, the role of Neolithic and Bronze Age barrows in the landscape is only now being studied.1 Beside the problems specific to each model, these explanations share several general problems. Firstly, they focus on only one aspect of urnfields, mostly the individual burial versus collective burial dichotomy. However, the urnfield burial ritual is a phenomenon consisting of several elements, such as specific types of pottery, metal work, burial forms, spatial organization, etc. A comprehensive model of cultural change, should try to incorporate all these elements and their meaning in its explanation. Secondly, the regional models are based on a limited understanding of the traditions and material culture from the end of the the Middle Bronze Age and the Late Bronze Age. In the models, Late Bronze Age and Early Iron Age urnfields are treated alike. The specific characteristics of urnfields form the Late Bronze Age, the formative period in the genesis of the urnfield phenomenon, are thereby overlooked. Also, little is known of the meaning of these traditions. Subjects like personhood, social memory and social practice have not been investigated for the urnfields from the Southern Netherlands. 1 This subject is currently being studied by Quentin Bourgeois as part of the Ancestral Mounds NWO research project on the social and ideological significance of barrows in the Netherlands, headed by dr. David Fontijn. 10 Lastly, there are some theoretical problems with the current models. These are mainly the general problems of a post-processual framework (see chapter 2), such as an inability or disinterest to relate ideological changes with transformations in material conditions or European politics. More important is the inability to get from short-term, individual-centred scenarios to long-term, structural changes. In the given explanations long term processes of culture change are not properly modelled, but rather logically inferred. Instead of building statistical models that show how in specific social, cultural and material conditions subsequent actions by individuals can lead to changes in burial customs, the explanations given so far have all inferred the outcome of such complex processes by logic. This can be a tricky enterprise as apparent logic may be misleading. Taking these critiques into account, the current study will adopt a different approach in which urnfields from the southern Netherlands are studied as a complex consisting of different elements. The characteristics and meaning of all these elements will be established, with an explicit focus on the burial customs of the Late Bronze Age and the preceding Middle Bronze Age B. A theoretical framework will be adopted that allows proper modelling of the long-term processes that led to the adoption of these customs (see chapter 2). With such an approach the main research goal of this study will be obtained, which is: Modelling when, how and, most importantly, why the urnfield phenomenon was adopted in the Southern Netherlands. Such a regional model will nuance current notions on the nature and spread of urnfields on a European scale. 1.3 Research Questions The research objective will be obtained by answering three main research questions, each divided in sub-questions. The answering of these questions make up the three steps needed to come to a proper model of culture change (see chapter 2). The first step is a description of the material culture and traditions of the Late Bronze Age: a basic story of what, when and where. The second step is determining the ideas behind this behaviour. This is needed as it was not just behaviour that spread throughout Europe in the Late Bronze Age, but rather the ideas behind it. Lastly, the social, cultural and ecological context will be reconstructed as these set the conditions for the spread of the new burial customs. 1 When, where and in what form were the elements of the urnfield phenomenon introduced in the Southern Netherlands? The urnfield phenomenon is traditionally seen as a “revolutionary” development that rapidly spread from Hungary to France and from northern Italy to southern Scandinavia. However, there is archaeological evidence that in some regions these novel traditions are actually continuations of local 11 practices and material culture, for instance in the Southern Netherlands (Ruppel 1985; Verwers 1971). The traditions and material culture of the Middle Bronze Age B and Late Bronze Age in the MeuseDemer-Scheldt region are poorly known. In this part of the study I will characterise each of the elements making up the urnfield burial ritual from these periods in the southern Netherlands. Research focuses on the following questions: The switch of inhumation to cremation is one of the most prominent new features of urnfields. When and how was cremation as a predominant form of treatment of the dead introduced in the southern Netherlands? In many regions monuments in urnfields have new and different forms than earlier barrow cemeteries. When and how are new forms introduced in the southern Netherlands? One of the traditional new elements of the urnfield phenomenon is the introduction of continental types of metal objects. When and how does the cultural composition of metal assemblages in burial context change in the southern Netherlands? ‘Urnfield ceramics’ are one of the clearest manifestations of the urnfield phenomenon. The range of forms is immensely more diversified and the fabric and production techniques are different compared to the earlier Middle Bronze Age. The question therefore is when and how do ceramic traditions change in the southern Netherlands and how drastically? In what contexts were these kinds of items used and ideas about them exchanged? 2. What is the meaning of the different elements of the urnfield phenomenon? Urnfields are often considered a phenomenon with a uniform meaning across the continent, but there are indications that the meaning behind differed between regions. However, the exact social and cultural significance of these cemeteries in the southern Netherlands is ill understood. Recent research indicates that urnfields may have been more than ‘just’ cemeteries. Through their long use and fixed location in the landscape they became the symbolic and ritual foci of local communities (Gerritsen 2003). Nevertheless, important subjects as personhood, ancestry and social practices have never been studied for urnfields in the Meuse-Demer-Scheldt region. In this part I will therefore determine the meaning of the practices described in the previous part. Research focuses on these questions: Are there patterns in the placement of graves and the way Late Bronze Age urnfields grew? How do these patterns reflect social structure? 12 The shapes and sizes of monuments, burial forms and urns show more differences in treatment of the dead than in previous periods. What kinds of persons were buried in Late Bronze Age urnfields? Is there a relationship between certain categories of persons or ancestors and the shape, size and positioning of burial monuments? 3 How can the genesis of urnfields be explained as part of a wider social, cultural and ecological context and the changes therein? Urnfields are generally studied as an isolated phenomenon. However, it is almost self-evident that they were an integral aspect of much broader cultural, social and ecological context. For instance, in the last decennium studies that compared developments in settlements and depositions with those of burial rites, have demonstrated that the genesis of urnfields was not only a sudden change in burial practices (Fokkens 1997; Fontijn & Fokkens 2008). This may sound logical, but in fact integrated, holistic approaches to Late Bronze Age societies are almost completely absent. The social and cultural context of the southern Netherlands has recently been extensively studied (Gerritsen 2001; Fontijn 2002), but the findings of these studies have not yet been incorporated in the modelling of the genesis of urnfields. The present study will draw other dimensions of life into the analysis, as these set the conditions in which new customs are rejected, adapted and/or transformed. Research focuses on the following questions: Which developments occurred in the Middle and the Late Bronze Age in the settlement domain? What information does this provide about changes in social structure and ideology relating to developments in burial ritual? How did the nature of ritual depositions develop in the Middle and the Late Bronze Age? What information does this provide about changes in social structure and ideology relating to developments in burial ritual? Which developments occurred in the Middle and the Late Bronze Age in economy and ecology? How did changes in material conditions affect the adoption of burial customs? Which developments occurred in the Middle and the Late Bronze Age in demography and population structure? How did this affect the manner in which ideas behind burial rites were shared? 13 Which developments occurred in the Middle and the Late Bronze Age in communication channels at both a local, regional and supra-regional scale? How did this affect the manner in which ideas behind burial rites were shared? Which developments occurred in the Middle and the Late Bronze Age in power relations and social strategies? How did this affect the manner in which ideas behind burial rites were shared? 1.4 Spatial and Chronological Framework In closing I shortly want to specify the geographical and chronological focus the study. The southern Netherlands is taken to comprise the provinces of Noord-Brabant, Limburg and parts of Gelderland, with the rivers Meuse and Rhine as the northernmost boundary (fig. 1.1). The southern and eastern edges of the study area are formed by land borders. These are, of course, arbitrary borders. Both culturally and geographically the southern Netherlands is part of the wider cover sand area between the rivers Meuse, Demer and Scheldt. Nonetheless, these arbitrary borders are maintained for practical reasons, mainly to downsize the workload. But obviously, ample reference will be made to finds from the wider Meuse-Demer-Scheldt area throughout this study. Chronologically the study is confined to the Middle Bronze Age B (1500-1050 BC) and Late Bronze Age (1050-800 BC). The Dutch periodization differs in terminology from the surrounding areas, where the Hallstatt and La Tène periodizations are mostly used. The reason for this is that material indicators used to date assemblages to phases of the German and France chronologies are often lacking in the Dutch archaeological record. The Dutch periodization and corresponding central and western European chronologies are shown in figure 1.2. In the southern Netherlands the start of the urnfield period is set at approximately 1050 BC, as the earliest 14C dates for urnfield burials date to the 11th century BC and clear Urnenfelderkultur influences in pottery do not pre-date the Ha A to B transition (Van den Broeke 1991, 193-4). However, changes in burial customs are already visible in the preceding Middle Bronze Age B, for instance in the appearance of oval burial monuments of the Riethoven type (Lanting & Van der Plicht 2003, 222; Delaruelle et al. 2008). The urnfield period of the southern Netherlands ends in the early stages of the Middle Iron Age, at about 400 BC. This is unlike central and western Europe, where the period is confined to the Late Bronze Age. The main focus of the current study will, however, be on this period. Of course, inevitably with an excursion into the Early Iron Age, now and then. 14 Fig. 1. 2 Chronological terminology of north-west European regions in use for the period under study. (Fontijn 2002, fig. 1.4) 15 16 Chapter 2 2.1 Theory of Culture Change Past and Current Theoretical Frameworks Given the immense time depth of the archaeological record, it is acknowledged by many that the strength of our field of study lies in characterizing long-term patterning in past societies and their material remains (Shennan 2002, 10). It should therefore not be a surprise that archaeologists have produced a vast amount of theory to make sense of this patterning. In the first paragraph of this chapter a brief and very general overview shall be given of the theoretical developments in the study of long-term cultural change. As a result of the importance of cultural change to archaeological studies, these developments coincide with the main developments in theoretical paradigms. The paragraph will end with noting some major problems with the current way of thinking about culture change in the study of the later prehistory of north-western Europe. In the next paragraph an alternative theoretical framework shall be presented to overcome these problems. The period before the 1960’s is often characterized as the period of ‘long sleep’ of archaeological theory. Culture was defined as constantly recurring types of remains, which are the material expression of a people (Childe 1929, v-vi). Changes in culture were explained as coming from the outside: through migration or diffusion – the spread of ideas through contact between groups. This normative view of culture – the assumption that artefacts are expressions of cultural norms – resulted in mere descriptive accounts, consisting of chronological and spatial sequences of cultures. In the 1960´s and 70´s several archaeologists who were dissatisfied with the descriptive archaeology of culture-history argued for an archaeology that was more scientific and anthropological. According to these scholars of the New Archaeology the dominating normative view of culture – that artefacts are expressions of cultural norms – could not explain why certain people have certain norms and how the different cultural elements fit together. They therefore adopted a different view of culture. Different parts of a culture – institutions of religion, economy, politics, etc. – were thought to be related to each other and thus formed a functional system, adapted to an outside environment. Crosscultural generalizations on processes of cultural adaptation were used to model the functioning of such systems. A critical response to a set of failings of the New or Processual Archaeology was formulated in the 1980’s, known as postprocessual or interpretative archaeology. Postprocessualists believe that cultures are not adaptations to an external environment, with individuals being mere pawns in such functional systems. Rather individuals are active and as such are the agents of social change through their actions. As these actions are based on culturally constructed knowledge, processes are always historical. Such an understanding of processes makes agency – the active social strategies of knowledgeable individuals – an important object of study. The central idea is that people are born into 17 existing structures and in acting reproduce but also transform this structure. Many postprocessualists have borrowed ideas from Anthony Giddens (1984) and Pierre Bourdieu (1977) on this recursive relationship between structure and agency (e.g. Barrett 1994). However, the importance of agency, historicity and ideology in postprocessual archaeology has resulted in a rigid focus on the local and short-term in current studies of north-western European prehistory. An approach which has recently been criticized by several scholars (e.g. Kristiansen 2008; Gerritsen 2001, 19-23), as summarized by John Robb (2004, 5): “Because interpretation has focused upon local scenarios, there has been little use of agency to explain long-term, large-scale or comparative patterns of change. A reaction against functionalist approaches has led to neglect environmental, demographic and economic contexts, and a focus on meaningful human experience in a short-term present has sometimes led to interpretations lacking a developed politics and economics. More generally, relations between enduring structures and the actors’ freedom to reconfigure or reinterpret them in action remain poorly explored (as indeed they are in social theorists such as Bourdieu, in spite of his post-structuralist polemic); Giddens’ ‘duality of structure’ is sometimes invoked as a rather mystical mantra to cover this problem rather than a tool for probing it.” Of these flaws the ‘micro-macro’ problem is the most salient one for this study, as cultural changes – such as changes in burial rites – are always structural changes beginning at an individual level. Up till now no satisfying solution has been found to overcome this dichotomy between the post-processual focus on short-term, individual-centred, local scenarios and the study of long-term, large-scale, structure-level processes in which these scenarios result. Fokke Gerritsen – who has discussed the genesis of the urnfield burial rite in the southern Netherland as part of his PhD-thesis (see chapter 1) – has struggled with this very issue. Gerritsen (2001, 13-23) notes that current approaches that focus on the individual human agent and adopt a ‘dwelling perspective’ are perfectly suited to monitor synchronic variation, but that this comes at the expense of interests in diachronic developments. He argues that rather “a long-term perspective (…) implies a view of the past in which relatively more emphasis is placed on collective ideas, values and dispositions than on experience and individual understandings of the world” (Gerritsen 2001, 21). However, I believe that with this assumption Gerritsen maintains the improper dichotomy between the short-term and the individual, on the one hand, and the long-term and the collective, on the other. In my opinion, a long-term perspective does not imply more emphasis on collective ideas, values and disposition, but rather on the transformation of these collective ideas, values and disposition. And these transformations are effected by individuals through agency. So what is needed for a diachronic perspective is not a change of focus onto the collective, but rather a theoretical framework that can combine both individual agency and the changes in collective ideas, values and dispositions that this agency brings about. 18 In the following paragraph I will present such a theoretical framework: gene-culture coevolutionary theory. This framework allows one to study long-term cultural and social change by starting with modelling the life of individuals, including their social-strategies and intentions. Such life-histories can be placed in their proper social, cultural and material contexts and their effects on social structures extended in time through statistical modelling. With an emphasize on individual decision-making, historical contingency and social strategy this framework has much in common with current post-processual theory, but instead of relying on logical inference to probe long-term processes of cultural change it uses mathematical simplification. As such, it allows for a diachronic perspective that combines both individual understanding and structural changes. 2.2 Gene-Culture Coevolutionary Theory Human behavioural ecologists and evolutionary psychologists, on the one hand, and much of social science, on the other hand, have since long quarrelled about the relative significance of genes and culture as the cause of human behavioural variability. In the 1970’s and 80’s several theories developed which explained human behaviour as the result of simultaneous and interacting cultural and genetic processes (Feldman & Cavalli-Sforza 1976; Cavalli-Sforza & Feldman 1981; Lumsden & Wilson 1981; Boyd & Richerson 1985). According to these theories culture is thought to be (indirectly) generated and shaped by genetic imperatives, while cultural traits alter the social and physical environment under which genetic selection operates. Together, genes and culture instruct the human phenotype and are being transformed through replication in a given environment. This idea is known as ‘gene-culture coevolutionary theory’ (or ‘dual inheritance theory’). Proponents of the geneculture coevolutionary theory argue that culture evolves (Richerson & Boyd 2005, 58-98). With this they mean something quite different from the unilinear theories of human progress, debated by generations of anthropologists. A key concept of gene-culture coevolution is the process of cultural inheritance. People acquire beliefs, skills, attitudes and values from other people by imitation and social learning. Human populations form pools of culturally acquired information, on which processes act that cause some cultural variants to spread, while others disappear. This cultural system of inheritance possesses key properties for selection to occur: cultural variation is heritable, cultural variants affect the phenotype (behaviour), and the total number of existing cultural variants is limited (as cognitive resources and control of behaviour are limited). 2.2.1 What Evolution Is (Not) Before explaining what cultural evolution is according to coevolutionary theory, I will first explain quickly what evolution is. Or rather what it is not. Firstly, evolution is not group adaptation. Archaeologists often wrongly associate evolutionary thinking with New Archaeology and group adaptation. New Archaeology explained culture as a process of group adaptation to an external environment, in which systems remain in equilibrium with their environment until an external 19 incentive leads to instability. This idea contains three major flaws. Firstly, there is an over-dependence on adaptationist thinking: there is more to Darwinism than natural selection, and natural selection itself is a heterogeneous complex of processes (Bettinger et al. 1996, 141). Secondly, following evolutionary biologists and ecologists, the notion of group adaptation as the main force of cultural evolution should be rejected because it appears theoretically invalid. Selection acts on individuals or closely related kinsmen. In cultural systems individuals are the main source of variability and the adaptation of such a system is therefore the result of the combined effects of individuals (Maschner & Patton 1996, 90-1). Thirdly, the argument of ‘nothing changes until pushed’ is an assumption with no real basis (cf. Maschner & Patton 1996, 93). In accordance with the biological concept of adaptation, gene-culture coevolutionary theory focuses on the individual, i.e. individual decision-making processes. This stress on events in the lives of individuals leads to a replacing of the ‘stable until pushed’-premise of processual archaeology. “Systems are always in a state of readjustment, experimentation, and change because the individuals in them, at least some individuals, are always attempting to manipulate the structure in their own, or their kinsmen’s, self-interest.” (Maschner & Patton 1996, 93). Several other popular, but wrong ideas about evolution need to righted too. Evolution “is not: progress or improvement (it is simply cumulative and transmissible change); genetic selection or ‘Darwin’s theory’ (these are instead ideas about the mechanisms of evolution in a specific context, namely, organic evolution); or an exclusive property of genetic systems (many things can and do evolve)” (Durham 1991, 21). Evolution is simply “descent with modification”, as defined by Charles Darwin in The Origin of Species (1859). This phrase has general applicability: it does not specify what it is that evolves, nor does it say how change or “modification” comes about (Durham 1991, 21). So, the genetic system based on DNA is not the only valid system of inheritance. An evolutionary system only needs to meet the following requirements (Durham 1991, 21-2). It has to have: 1. Units of transmission 2. Sources of variation 3. Mechanisms of transmission 4. Processes of transformation 5. Sources of isolation In the following paragraphs I will show how a system of cultural evolution meets these requirements. 2.2.2 Ideational Concept of Culture First, we will need a proper definition of what culture is. The definition used throughout this study is given by Robert Boyd and Peter Richerson (2005, 5): “Culture is information capable of affecting individuals’ behaviour that they acquire from other members of their species through teaching, 20 imitation and other forms of social transmission.” Two features of this definition need to be pointed out (after Shennan 2002, 37-8). First, culture is not behaviour. Culture influences or guides behaviour, but genes and the environment people live in do so too. This is a salient point for archaeologists, as it means that material remains are behaviour, not culture. Secondly, not all information that affects behaviour is cultural. Only information that is inherited from other members of a species is considered culture. 2.2.3 Mechanisms of Transmission Now that we have established that the genetic system is not the only inheritance system possible, let us look at what evidence there is to suggest that culture is a system of inheritance. How is culture inherited? The main mechanism of cultural transmission is social learning (Shennan 2002, 38-42). Simply put: ideas get from one head to another by people imitating each other. Contrary to other animals, who mainly learn by a trial-and-error from their environment, humans depend for a large part on cultural traditions passed on by social learning to make a living. Traditional craft skills and abilities to exploit nutrient-dense food sources often require considerable knowledge. It takes the greater part of pre-adolescent life to acquire this knowledge. Perfecting these skills often takes the greater part of a life-time. For instance, 25-50 year old Ache foragers in Paraguay acquire on average 7000 calories of meat per day, whereas 18-20 year old foragers acquire just 1530 calories per day (Kaplan 1996, 105). This extensive knowledge is mainly socially learned from parents or another individual of the older generation, as shown in several studies of how traditional skills and task complexes are learned in traditional societies (Shennan & Steele 1999; Hewlett & Cavalli-Sforza 1986; Ruddle 1993). A review by Boyd and Richerson (1985, 46-55) of a large amount of psychometric and sociological evidence shows that social learning results in an inheritance system with high similarity in behaviour between those passing on the information (consciously or unconsciously) and those imitating it. A heritability that is as high as or even higher than that in non-cultural species. The effects of cultural inheritance are difficult to distinguish from genetic and environmental effects in the case of studies of psychological traits, such as cognitive ability, personality and temperament. However, assuming that sociological traits like skills, norms, and political and religious attitudes are less likely to be genetically acquired than psychological traits, these studies provide convincing evidence for cultural transmission. High correlation exists between parent and offspring for attitudes toward religion, political party affiliation, and occupational interests. It also appears that mother-offspring correlations are slightly higher than father-offspring correlations, which is to be expected in the case of cultural transmission given the greater involvement of women in child rearing. But culture is not only transmitted between parent and offspring. There are more routes of transmission for memes than there are for genes. As genes descent through sexual reproduction, we inherit most of them equally from our mother and father. Even when memes are inherited from parents 21 (vertical transmission), it is unlikely that we inherit 50% of them from each parent. Daughters are more likely to learn from their mothers, and sons from their fathers. Besides, there are several routes of transmission that have no parallel in genetic systems of inheritance. Individuals can acquire ideas from an individual of an older generation other than their parents (oblique transmission). Or they can acquire information from their contemporaries (horizontal transmission). Also, unlike genes, information can be transmitted one-to-many or many-to-one. In the former case new ideas can spread quickly through a population. The latter occurs when all members of an older generation insist on certain values or practices in their interaction with members of a younger generation. In this case change is slower than in one-to-one or much slower one-to-many transmission. Table 2.1 gives an overview of the possible routes of transmission and their characteristics and consequences. Table 2. 1 Different routes of cultural transmission and their suggested implications in terms of cultural uniformity and speed of change. (Shennan 2002, fig. 4) 2.2.4 Units of Transmission So if social learning is the mechanism by which information is transmitted, than what is it that is being transmitted? What are the units of inheritance? The best-known answer to this question is the concept of the meme, formulated by Richard Dawkins (1976, 189-201). The meme is a unit of cultural inheritance which reproduces faithfully, lives long enough to affect the world, and can make multiple 22 copies of it self. Memes are replicators, just like genes. However, many doubt the view that ideas are replicators, faithfully copying their selves. For instance, the cognitive anthropologist Dan Sperber (1996) argues that ideas are not transmitted intact from one brain to the other. Instead people generate rules, beliefs or ideas from observing other people’s behaviour. Developmental, cultural or genetic differences among people may lead to them generating different rules from the same behaviour. So it appears that the ‘meme as replicators’ idea has significant problems. However, ideas and beliefs do not have to be like genes in order for cultural evolution to take place. All that is needed is that cultural continuity exists. And we archaeologists know it does. So we can theorize about cultural evolution, even though we do not exactly know what the cultural units of transmission are (cf. Richerson & Boyd 2005, 80-1). Similarly, substantial progress is made on understanding organic evolution, while we still don’t know exactly how genes translate into properties of organisms. I will therefore maintain the term meme throughout this book, even though it is flawed, because it self is a catchy meme. One thing has to be made clear about units of cultural inheritance: the units of inheritance need not be small, independent bits. Many anthropologists consider culture to exist of integrated systems of shared meaning. They eschew a notion of cultural evolution along Darwinian principles, since it would mean that culture needs to be broken up into small, independent parts. However, a Darwinian understanding of cultural evolution can be gained even when culture is considered a complex (Richerson & Boyd 2005, 90-1). But the question is: how is culture transmitted? Boyd et al. (1997) have formulated four hypotheses on how culture descents: Culture descents as a whole According to this view, cultures can be seen as biological species: cultures are tightly integrated and isolated from each other. In the course of evolution cultures act as single entities, because they contain within them powerful sources of isolation and coherence. However, such a holistic view of culture is hard to maintain as there is much evidence for substantial diffusion and rapid evolution in many components of culture. Culture descents as core traditions Like in the previous hypothesis culture is assumed to be an ideational system. Cultures consist of hierarchically integrated systems, each with its own internal gradient of coherence. At the one extreme of the gradient there are ´core´ components of a culture, generated by processes of coherence (see below). This core consists of the ideational phenomena that constitute the conceptual and interpretive framework of a culture. At the other extreme of the gradient are ‘peripheral’ elements that are only lightly or not at all influenced by the core. These elements therefore change rapidly and diffuse widely. Examples of such cultures might be found in the Athapaskans of northern Canada (Rushfort & Chisholm 1991), Polynesian islanders (Kirch 1986), Indo-European traditions (Gamkrelidze & Ivanov 1990), and Tupi speakers of southern America (Durham & Nassif 1991). 23 Culture descents as small components In this hypothesis, culture does not exist of one core cultural tradition of special significance, but rather several cores and sometimes quite small units. Collections of memes diffuse and recombine rapidly, compared with memes within collections. Coherence within the components is created by the same processes as for the hierarchical cores of the previous hypothesis. The presence of several smaller components, rather than larger, coherent units, can be expected theoretically. As we have many cultural parents (see above), the potential exists for independent samples of culture from many sources. This hyperrecombinatorial nature of the cultural inheritance system provides a serious obstacle for maintaining coherence in a large cultural unit. Mixing is less effective within small units, because one can learn one thing from a small group of cultural parents and another thing from another group of parents. This leads to small but coherent subcultures in a larger cultural complex. Examples of the descending of small components are the spread of the Sun Dance on the Great Plains of America, or the spread of Islam from Western to Central and Northern Asia and Northern Africa. Culture descents as memes This last hypothesis states that there are few multimeme complexes. Rather the cultural things we observe are affected by many memes. These memes diffuse rapidly between groups and memes that affect different cultural things readily recombine. Boyd et al. (1997) describe several mechanisms that create coherence between cultural elements. According to symbolic and interpretive anthropologists it is ‘meaning’ which provides the glue in culture. Meaningful cultural information helps making sense of the natural world and of cultural and social systems. It also legitimizes these systems. This information often has a sacral status as it is important to an individuals understanding of the world. However, it does not need to be exclusively linked to cultures as a whole. It can also be linked to smaller units. There are several ways in which a system of meanings can create coherence. Foreign elements may be known to individuals, but foreign values or ideas are misunderstood, disliked and neglected because of a mismatch of meaning between cultures or subcultures. Second, meaningful culture often involves markers of group identity. The contexts in which coherent, meaningful cultural units can be acquired from foreigners are likely to be of a ritual nature. Such contexts mobilize ethnocentric sentiments and thereby provide a barrier to diffusion. Third, the coherence of culture is protected from ordinary adaptive evolutionary processes because of the systemic nature of meaningful cultural information. Lastly, cultural coherence my be maintained because certain combinations are favoured by natural selection or derived adaptive decision-making rules (see below). A variant on this is that coherence is maintained because it sustains a stable social strategy. Even a small movement away 24 from a current practice could be disadvantageous. Foreign social practices may therefore be rejected because they fail to fit into existing social arrangements. Table 2. 2 A list of cultural evolutionary forces (Richerson & Boyd 2005, table 3.1) 2.2.5 Sources of Variation and Processes of Transformation Now that we have seen what culture is and how it is transmitted, let us take a look at how variation and transformation in culture comes about. As with routes of transmission, the sources of variation and processes of transformation in cultural evolution are not fully the same as for organic evolution. Students of gene-culture coevolution have distinguished several forces of cultural evolution: random forces, decision-making forces and natural selection (Richerson & Boyd 2005, 58-98; Shennan 2002, 51-60). These are summarized in table 2.2. I will now further explain these. Random forces are processes analogue to mutation and drift in genetic transmission. Random mutation in cultural information, unrelated to processes of selection, can occur. For instance, when people make copying errors and alter their behaviour without knowing. When some people begin to copy this behaviour cultural evolution will start. Another random force of cultural evolution is drift. 25 We can speak of drift when the frequency of a meme in a population changes not as the result of selection (cultural or natural), but as the result of chance. Drift can occur in any finite population, in which chance always has a part to play in the transmission of information. In small populations chance events have a significant likelihood to outweigh the effect of selection. Chance has especially a large part to play in the transmission of neutral information, in the sense that no selection is acting upon them. A well-known example is stylistic attributes, often contrasted in archaeology to functional attributes (Dunnell 1978). Decision-making forces result when people given a choice between two alternative behaviour patterns, preferentially choose one cultural variant over another. Two types of decision-making forces exist. Individuals may modify existing behaviours or invent new ones, called guided variation. When people prefer a certain cultural variant on basis of cultural rules or genetic predispositions, this is called biased transmission. A bias may, for instance, result from a preference for the content of the cultural variant (content-based or direct bias). People may change their way of doing as the result of comparing the outcome of their current behaviour with that of another individual. A bias may also result from the commonness or rarity of a variant (frequency-based bias). People can look around them and either do what most people do (conformist bias) or do the opposite (non-conformist bias). Lastly, a bias may result from the observable attributes of the individuals who exhibit the variant (model-based or indirect bias). In this case beliefs are not copied for their own content, but, for instance, because the individual displaying them appears successful or prestigious to local criterion. Or because the individual looks like oneself. Lastly, the frequency of a cultural preference can be directly changed by natural selection. Natural selection in organic evolution is the “differential reproduction of genotypes” (Durham 1991, 12). Changes in the frequency of genes in a population depend for a large part on the survival and reproductive success of the individuals carrying them. To the extent that information is passed on from parent to child, natural selection acts on memes in almost similar ways as it does on genes (Richerson & Boyd 2005, 76). Indeed, sometimes the frequency of cultural variants might have changed in populations because certain beliefs led some people to have more (grand)children than others. However, when people are influenced by contemporaries, teachers, prestigious individuals, etc. natural selection can act on culture in ways quite different than it does in organic evolution. It can favour behaviour that increases the chance of attaining such a non-parental role. Whenever behaviour leads to being imitated more often than one would be when holding other behaviour, the meme instructing that behaviour will increase. Even when this behaviour is maladaptive seen from the gene’s point of view. Natural selection in cultural evolution can therefore be defined as “changes in the cultural composition of a population caused by the effects of holding one cultural variant rather than others” (Richerson & Boyd 2005, table 3.1). 26 2.2.6 Cultural Selection Having briefly discussed the forces of cultural evolution, there is one that deserves some further elaboration: the role of human beings as decision makers. Culture changes to a large extent under the influence of humans as guiding and selecting agents. You can say that in cultural evolution it is people, not nature that do most of the selection. The differential social transmission of memes as the result of human decision-making forces is called cultural selection. Or simply ‘preservation by preference’ (Durham 1991, 198). This form of selection can come in two modes. Humans can select cultural variants on the basis of free decision making, or ‘selection by choice’. Another possibility is that decision making is constraint by the social context in which it takes place. In this case people are not free to choose a cultural variant at will, but comply with the decision of others. This can be called ‘selection by imposition’ (Durham 1991, 198). But whether people acquire or reject a cultural variant by choice or by imposition, there is always evaluation of variants according to their consequences. An important question is therefore, on what basis do people assess a variant? The answer on this question is given by William Durham (1990, 199-201), basing himself on the works of George E. Pugh (1977) and Pulliam and Dunford (1980). They describe the ‘value-driven decision system’ located in the human brain, which endows humans with as system to assess the consequences of behaviour – experienced or expected – according to one or more decision criteria. People can then search for the optimal solution. The outcome of this system is therefore influenced most heavily by the values people hold. These values are influenced by both the genetical and the cultural inheritance systems. One can make a distinction between ‘primary’ and ‘secondary values’. Primary values are designed by organic evolution into our decision making system and develop generally out of the interaction between the environment and the nervous system. They are evaluative sensations experienced generally as good or bad, pleasant or unpleasant. Secondary values include “rules of thumb, wise proverbs, social conventions, moral and ethical principles, and even habit” (Pugh 1970, 33). Durham (1991, 201) ads to this, that values are secondary when they persist in a population as the result of social transmission. Secondary values stem from social history and collective experience. Note that these values themselves are cultural and therefore have their own history of cultural evolution. According to Durham selection on the basis of secondary values is the main force of transformation in cultural evolution. He calls this hypothesis 1 of coevolutionary theory, formally formulated: secondary value selection is the main but not exclusive means of cultural evolutionary change (Durham 1991, 204). So when the rate of change of the frequency of a cultural variant in population depends on choice, it will co-vary with evaluation according to the secondary decisionmaking system of the population. When the rate of change depends on imposition, it will co-vary with the secondary values of the imposers. The last question that needs to be answered is then: where do secondary values come from? What is their origin and why do they persist? Following Pugh again, Durham (1991, 207-210) 27 theorizes that primary values are substitutes for real evolutionary criterion of genetic selection – that is, reproductive success. Primary values will lead to the adoption of cultural variants that increase the genetic fitness of an individual. The secondary value system evolved as a further elaboration of this surrogate decision making system, also under strong genetic selection. Secondary values, acting as surrogates for primary values, make the system even more effective and efficient, but they are generally (but not always) in agreement with primary values. Secondary values were and are thus selected by the same decision-making system that they come to enhance. Early in human evolution secondary values will have been mainly selected by primary values. Through time the complex of secondary values extended and these values became further removed from primary values. And as long as these derived values do not oppose the primary ones, this process will continue ever on. However, feedback of the primary decision-making system will maintain a system of cultural selection in congruence with the criteria of genetic selection. Hypothesis 3 of coevolutionary theory therefore is: The main but not exclusive effect of the human decision system is to promote a general positive covariation between the cultural fitness of allomemes and their inclusive fitness values for the “selectors” (i.e. those who actually decide) (Durham 1991, 209). 2.3 Coevolutionary Theory, Systems-Thinking and Human Agency Having explained what coevolutionary theory comprises, I will in closing discuss how it relates to the notions of interpretative archaeology. The traditional social evolutionary view of the New Archaeology, based on the works of scholars as Leslie White and Elman Service, saw cultures as adapted through linked social institutions to an outside environment. Evolutionary biology critiques this view by noting that the starting point for an evolutionary perspective is not group adaptation but methodological individualism, i.e. the view that larger-scale entities merge from interactions between individuals (Shennan 2002, 212). The idea that social institutions arrive simply because people act in the interest of the group has been refuted since long by biologists. They explain that people that do so would loose out to individuals who prioritize their own reproductive success. Interests at the group level will be overridden by interests on the individual level if behaviour has any kind of genetic basis (Shennan 2002, 28-9). So if we want to understand how groups form and why they have certain characteristics, we need to start with the individual. Evolutionary biology shares this methodological individualism with post-processualism. And in fact, many more parallels exist between post-processualism and coevolutionary theory. As we have seen, both emphasize individual intentions and decision-making; both accord social strategies as much importance as subsistence; both recognize the role of the contingencies of history and the importance of “heritage constraint”; and both belief that actions and responses are culturally mediated by the values people hold in a specific cultural context (Maschner & Mithen 1996, 12). But where coevolutionary differs from interpretive archaeology, is in its methods. 28 The current stress in archaeological research on agency and historical processes led to a rigid focus on local scenarios and therefore often provides no explanation for long-term, large-scale change. Many social scientists have struggled with this ‘micro-macro problem’ and some are even convinced that the two approaches can never be unified. Starting with complex social institutions, how can one ever fit in individuals? Actually, the tools of Darwinian population thinking are designed to integrate individual and collective phenomena (Richerson & Boyd 2005, 246-7). They are by definition multilevel tools. In Darwinian models, what happens to individuals affects population properties. So where current archaeology has to do with logical inferring to describe the relation between individuals and the collective, coevolutionary theory has an already developed toolset to model this relationship. A postprocessual critique is, however, to be expected to Darwinian model building, mainly concerning the apparent use of generalizations in the models. According to postprocessualists behaviour cannot be predicted for the following reasons: “First, it is acknowledged that predictability of human behavior occurs within specific cultural contexts because actions and responses are mediated by cultural values. Prediction is, then possible, but only “from the inside.” Second, however, the knowledgeability of lay actors includes the ability to discern predictability of responses within historical traditions. Such knowledge can be used to contrive power and social change. The generation of the unpredictable is a social process and individuals create laws by their activities. As anthropologists we cannot make general deterministic laws about human behavior but we can identify the general principles by which individuals construct their worlds within culture-historical contexts.” (Hodder 1985, 7) As social actors are understood as active and thus generate social change, and their actions depend on knowledgeability that is culturally constructed, postprocessualists argue that all social change and processes are historically dependent (cf. Hodder 1985, 2-3). The use of Darwinian models and methods from population genetics may appear to ignore this historicity, by its focus on generalized processes of culture change. Such a critique would, however, be invalid. First of all, concerning human intentions, values and actions it is simplification, not generalization that typifies Darwinian models. Hodder himself points out that, even though deterministic principles do not exist, general cultural-specific principles can be identified. These cultural rules guide the actions of individuals and can be incorporated in Darwinian models as decision-making forces. These forces stem from both genetically predispositions and culturally acquired learning rules, which result in preferences for certain cultural variants (Richerson & Boyd 2005, 71-2). (Even genetically determined predispositions alone can lead to cultural specificity, since these lead to behavioural flexibility, not biologically determined behaviour (Shennan 2002).) Secondly, historical contingency plays an equal important role in organic evolution 29 as in social processes. Darwinian tools are therefore tuned in to study apparent unique historical trajectories (Richerson & Boyd 2005, 247-8). These tools can even explain how generalized evolutionary forces like natural selection can give rise to history (Boyd & Richerson 2005). So it appears that postprocessualists “have everything to gain and nothing to lose by using appropriate evolutionary tools for their job.” (Richerson & Boyd 2005, 248) 2.4 Studying Culture Change: Middle-Range Strategy Now that we have seen what coevolutionary theory is and what its advantages are, the last step is to show how we can use this theory in a practical manner. The basic steps of creating a Darwinian model of culture change are (Richerson & Boyd 2005, 97): -draw up a model of the life history of an individual; -fit an individual-level model of the cultural (and genetic, if relevant) transmission processes to the life history; -decide which cultural (and genetic) variants to consider; -fit an individual-level model of the ecological effects to the life history and to the variants; -scale up by embedding the individual-level processes in a population; and -extend over time by iterating the one-generation model generation after generation. Of course, processes of culture change often are of great complexity. I will therefore not try in advance to capture such complexity in several simple rules, typologies or hypotheses of culture change that subsequently need to be tested. I believe it makes more sense in the case of such complexity to adopt a theoretically informed inductive strategy to link the characteristics of the archaeological record to the properties of a process of culture change: or what Kristiansen (1998, 54) calls a ‘middle range strategy’. In a practical sense, this means that first several components of a model of culture change will be reconstructed in a theoretically informed way. Subsequently these components will form the building blocks for a Darwinian model of culture change. In the following I will discuss for each building block what it comprises. Most of these building blocks have already been discussed in previous sections and will therefore only be briefly discussed. Life History Life history theory is a set of ideas used in evolutionary biology, ecology, and evolutionary anthropology and psychology. It is concerned with the effect of natural selection on how organisms allocate their limited resources (e.g. time, effort and energy) through the course of a life time (Shennan 2002, 102-113). Available resources are limited in a given environment and resources used for one 30 purpose diminishes the resources available for other purposes. Questions asked are: How much effort should be devoted to parenting instead of mating? Should one reproduce many offspring in which little resources are invested or only a few in which much resources are invested? Those individuals who come up with the optimal allocation of resources given certain constraints will be most successful in terms of natural selection. However, as was noted earlier, natural selection on cultural variants can be quite different if information is not transmitted solely from parent to child. Natural selection in cultural evolution is simply changes in the cultural composition of a population caused by the effects of holding one cultural variant rather than others. The effects of the characteristics of a certain life course should therefore not be valued only in terms of reproductive success (i.e. organic evolution). In cultural evolution life history influences the extent to which an individual is imitated. Members of a population may have different life histories, according to sex, age, social position, etc, which result in differences in reproductive success, both in a cultural and an organic sense. I will therefore reconstruct the life history of the different kinds of individual involved in the transmission of the ideas behind the urnfield phenomenon to see how these different life histories might have affected the changes in burial rites. Transmission Processes As was said, cultural information passes on from one individual to another by social learning. And it does so with great accuracy. This is the most essential property of culture as a system of inheritance. However, much variation exists in how one learns and from whom. For instance, one can gain ideas and beliefs from his or her parents, from other individuals of an older generation, or from his or her peers. Information can be passed on one-to-one, one-to-many or many-to-one. Also, ideas can be transmitted by behavioural demonstration, verbal explanation, etc. All this variation can have significant effects on how culture evolves. For the different practices and elements making up the urnfield phenomenon – ceramics, burial forms, cremation rites, metal works – I will therefore reconstruct how the ideas and beliefs behind them were transmitted, using both archaeological data and cultural anthropological insights. Value Systems & Cultural Constraints According hypothesis 1 of coevolutionary theory, selection of ideas and beliefs on the basis of the cultural values individuals hold is the main force of culture change (Durham 1991, 204). As explained above, foreign ideas and beliefs might be misunderstood, disliked and neglected because of a mismatch of values between cultures or subcultures. In this way options may be blocked by cultural constraints, such as preconceptions, prejudices, and technological capabilities (Durham 1991, fig. 4.5). A thorough understanding of the value systems of Middle and Late Bronze Age societies in the Meuse-Demer-Scheldt area is therefore of the utmost importance. Fortunately, our knowledge on these value systems has been greatly expanded by several recent studies (Fontijn 2002; Gerritsen 2001). Use 31 will be made of the insights gained in these studies to reconstruct the value system of the societies under study. Ecology & Material Constraints Coevolutionary theory highly stresses the historical and cultural specificity of change, by noting that ideas are either accepted or rejected according to the criteria of a cultural value system. However, this does not mean that this value system provides the incentives of change. As said, people do not change beliefs and behaviour at random, but on the basis of the consequences of behaviour in a particular social and natural environment. These environments are unstable and provide the external stimuli for change. I will reconstruct the changes in the natural environment. By this I will identify the external stimuli of culture change, without explaining the trajectory or form of culture change (cf. Gerritsen 2001, 22). Social Environment & Social Structural Constraints Like the natural environment, the social environment provides incentives of change and therefore needs to be reconstructed. Also, society comes with several structural constraints in the form of power relations. Third parties can intervene on the transmission of information by imposing on decision making forces. Power relations and their effects on the decisions made by individuals will therefore be a focus of study. Demography & Population Structure To create a Darwinian model of culture change the individual-level processes need to be scaled up by embedding them in a population. Insight into population properties is therefore needed. It is assumed urnfields probably contain all the deceased members of a community in a certain region. Those urnfields that are fully excavated can therefore be used to reconstruct several demographical characteristics, such as population size, and changes therein (Kooi 1979, 167-179; Theuws & Roymans 1999; Lohof 1991, 252-256; Theunissen 1993, 40). One also needs to reconstruct the population structure, that is reconstructing the different social units, or ‘reference groups’, of which a population consists. “The reference group should be the collection of individuals in space and time that shares both the same inclusive fitness function and the same cultural fitness function. In other words, it is a group of individuals who face more or less the same set of options, who experience more or less the same set of consequences, and who respond with more or less the same pattern of transmission rates.” (Durham 1991, 210-1) Singling out reference groups is important, because it is to be expected that cultural evolution is driven by different forces or proceeds in different directions, or both, within each of the subpopulations present (Durham 1991, 211). For instance, as cultural evolution is often a political process, a cultural variant may be absent in one subpopulation not as the result of free choice, but as the result of imposition by another, politically 32 dominant subpopulation. In this case, a false understanding of the processes of culture change would be gained if differences in reference groups were not taken into account. Once these building blocks are defined all the information is present to formulate a model of culture change. We have a reconstruction of the life history of the different kinds of individual involved in the urnfield burial ritual. And we also know how these individuals share ideas about this ritual. These are the first two steps of a Darwinian model of culture change. We can subsequently model the effects of ideological, material and social constraints on the spread of the cultural variants that make up the urnfield phenomenon. These individual level processes can be embedded in a population, the characteristics of which have been reconstructed. Finally, the processes can be extended over several generations. 2.5 Structure of the Study The study consists of three parts, following the three main research questions as defined in chapter 1. The first part will be a description of the material characteristics of Middle Bronze Age B and Late Bronze Age funerary rituals. It was explained earlier that material remains represent behaviour, not culture. The first part of the study will therefore be a description of behaviour. Such a description is crucial, however, as it forms the basis for a reconstruction of the ideas behind them: the cultural variants. The reconstruction of the meaning of the elements making up the urnfield phenomenon is the second part of the study. Subjects to be considered are the personhood of the buried, group identity as expressed in the layout of the cemeteries, the nature of urnfields as communal ritual places, and social memory as articulated in the reference to older burial monuments. Many evolutionary archaeologists, including those working in a coevolutionary framework, argue, however, that culture change should be explained without behavioural reconstruction, which is considered ‘unscientific’ (Lipo et al. 1997). Rather one should investigate diachronic patterns in the frequency of material culture traits (cf. Shennan 2004; Lipo et al. 2007). However, I believe that this idea of objectivity is misleading. At least some degree of reconstruction is always needed, either when creating a model of culture change or after testing it (cf. Bettinger et al. 1996; Shennan & Wilkinson 2001, 592). Post-processual archaeology has developed an extensive array of theories and methods to study the behaviour and, especially, the cognition of the people behind the pots (e.g. Barrett 1994; Bradley 1998; Tilley 1994). I think it therefore makes sense to make use of these tools. Having established the patterns of change in the nature and frequency of the cultural variants that are part of the urnfield phenomenon, the last step is to describe the context in which these variants have spread. This comprises the third part of the study. In this part most of the building blocks for a Darwinian model of cultural change are described: the life history of the carriers of the variants, the relevant transmission processes, the cultural, social and material constraints, and the population 33 structure. Many of these topics have recently been analysed for the Late Bronze Age of the Southern Netherlands. The insights gained in these studies have, however, not yet been combined to provide a framework for explaining the genesis of the urnfield phenomenon. Using these building blocks I will formulate one or several hypotheses that explain the change in burial rites at the end of the Middle Bronze Age. These hypotheses will be presented as mathematical models which generate patterns that can be compared with those described in the first and second part of the study. 34 Chapter 3 3.1 Changes in Traditions and Material Culture Introduction This chapter forms the first part of this study of the genesis of urnfields in the Southern Netherlands. A study of culture change has to start with a thorough description of the material characteristics and traditions current in subsequent periods and the frequency in which these occur. In this chapter a description will, therefore, be given of the material characteristics and practices of Middle Bronze Age B and Late Bronze Age funerary rituals. Previous models that have tried to explain the coming of the urnfield phenomenon in the Southern Netherlands lacked a comprehensive understanding of these traditions. They were based on a general knowledge of the burial practices of the Middle Bronze Age and treated the Late Bronze Age and Early Iron Age components of urnfields alike. Also, they tended to focus on a single element of the urnfield burial ritual. Recent overviews of Middle Bronze Age burial practices and new 14C dates for the Middle Bronze Age B make a better understanding possible of the period before the arrival of the urnfields. With an inventory of Late Bronze Age burials the practices of this period will also be better known. Thus I can answer the first set of research questions: how and when did the burial monuments, burial practices, ceramics and metals that were characteristic for the urnfield burials introduced in the southern Netherlands? 3.2 Data & Methodology A description of funerary material culture and traditions, of course, has to start with an inventory of all graves from a certain period and region– in this case all Middle Bronze Age B and Late Bronze Age graves from the southern Netherlands. Inclusion of a grave in such an inventory is based on the dating of the burial. Typo-chronology of burial goods or grave-structures and radiocarbon dating are the main means for dating later prehistoric burials. In the following the peculiarities and difficulties of dating Bronze Age graves shall be discussed. 3.2.1 Dating Middle Bronze Age Graves For dating Middle Bronze Age burials from the Southern Netherlands two typo-chronological developments are significant, that of pottery and that of the surrounding features of barrows. Metal grave goods only play a small part in dating barrows, as only 4,3% of the graves contain bronzes, which all date to the Middle Bronze Age A (Theunissen 1999, 87). I will shortly discuss the validity of typo-chronology as a means for dating Bronze Age graves, starting with the surrounding features. The Bronze Age of the Netherlands is divided into the following periods (De periodisering.. 1965/66; Lanting & Mook 1977; Van den Broeke 1991, 193-4): the Early Bronze Age (2000-1800 BC); the Middle Bronze Age A (1800-1500 BC) and B (1500-1050 BC); and the Late Bronze Age (1050-800 BC). Throughout the Bronze Age and the preceding Late Neolithic barrows were being 35 erected in the Netherlands which often were surrounded by distinctive features, such as different kinds of ring ditches and post circles. It is supposed that in each period of the Bronze Age a different kind of surrounding feature was prevalent. In the Early Bronze Age featureless barrows were erected, in the Middle Bronze Age A barrows had a ring ditch, while in the Middle Bronze Age B post circles dominated (Drenth & Lohof 2005, 440-2). Recently the dating of each type of surrounding feature has been critically reviewed by Quentin Bourgeois. Giving an overview of all barrows that can be securely dated on the basis of radiocarbon dates and typo-chronology of grave goods, he found that the different types of surrounding features (including the featureless barrow) are roughly contemporary and that almost all barrows fall within Middle Bronze Age A and the first quarter of Middle Bronze Age B (Bourgeois & Arnoldussen 2006; Bourgeois in prep.). So it appears that surrounding features have, for now, lost their significance as a means for typo-chronological dating. The second manner in which Middle Bronze Age graves can be dated is through typochronological developments of pottery. For the Middle Bronze Age three types of pottery have been defined by Glasbergen (1969) on the basis of the shape, rim type and decoration of pots. These types are part of a typo-chronological development, beginning with Hilversum pots. Hilversum pottery (HVS) is characterized by more or less biconical pots, both with and without cord, nail or hollow bone or reed impressions on the collar (triangles, meshes, groups of vertical lines, wavy lines, groups of ovals, or series of circles) and sometimes cord or nail impressions on the rim (triangles, parallel lines, or sometimes a single line). Some Hilversum pots have horseshoe shaped handles. Later HVS pots have a more ‘truncated-pear shape’ (afgeknot peervormig), and are sometimes decorated with cord impressions, but mostly with nail impressions (Glasbergen 1969, 14, 18-9). These develop into Drakenstein pots (DKS), which are more or less ‘truncated-pear shaped’ or bucket shaped. According to Glasbergen the earliest DKS pottery types have an inward slanting rim, often with a fingertipdecorated cordon (stafband). The later types have a rounded rim and perhaps a row of fingertip impressions several centimetres below the rim, if decorated at all (Glasbergen 1969, 19). The youngest type is Laren pottery (LR), which is barrel or bucket shaped, mostly undecorated (only sometimes a row of fingertip impressions underneath the rim) (Glasbergen 1969, 27). According to Glasbergen (1969) DKS and LR pottery represented typological devolution from HVS pottery and therefore a chronological development. Later, 14C dating (Lanting & Mook 1977, 117-9) showed that HVS pots are always early, but that DKS pottery both occurred in the earlier and later periods of the Middle Bronze Age. So DKS and HVS pottery coexisted over a long period of time. According to the 14C dates used by Lanting and Mook LR pottery indeed is younger than HVS pottery. Taking these insights into account Ten Anscher (1990, 72-7) proposed to abandon the HVS, DKS and LR phases and replace them with a HVS-1, HVS-2 and HVS-3 phase respectively. The HVS-1 phase contains both HVS and DKS pottery, with a diminishing amount of horseshoe handles and knobs, cord impressions and concave inwardly bevelled rims with a pressed outside (Glasbergen’s rim type A) from HVS-1A to 1C. In the HVS-2 phase only 36 DKS pottery is present and in HVS-3A both DKS and LR pottery are present. The development ends with phase HVS-3B, consisting of assemblages with only LR pottery. More recently Theunissen (1999, 202-6) has given a chronological overview of decoration elements on Middle Bronze Age pottery from 14C dated settlements and burials. This overview show that barbed wire decoration, cord impressions, pared nail impressions, concave inwardly bevelled rims with a pressed outside (rim type A), and decoration on the inside of the rim are early elements occurring between ca. 1870 and 1530 BC. Fingertip decorated cordons, nail impressions on and beneath the rim, and undecorated pottery appear throughout the entire Middle Bronze Age. So it appears that the elements characteristic for HVS pottery (cord impressions, paired nail impressions, and rim type A) have an early dating, and therefore this pottery has both typological and chronological significance. As both DKS and LR pottery are defined by elements (decorated cordons, nail impressions, absence of decoration) that are long lasting it is impossible to define a DKS and LR phase or HVS-2 and HVS-3 phase. This pottery only has a typological significance. Theunissen suggests to only use the term HVS pottery for assemblages containing early elements and to designate assemblages without these elements ‘Middle Bronze Age B pottery’. Similarly Fokkens (2001, 248-9) suggests the term ‘Early Hilversum’ for pottery containing early elements and ‘Late Hilversum’ (after 1500 BC) for pottery without them. From this discussion it appears that the different Middle Bronze Age pot types do have chronological significance, but that only complete pots allow to be dated. Dating pottery fragments by decorative elements is only possible in the case of HVS pottery, as LR pottery is characterized by elements that on their own have no chronological significance. To make matters worse, a Middle Bronze Age A date for a LR pot was recently published by Lanting & Van der Plicht (2003, 160-1, Cuyk 1965-216). So it appears that typo-chronology provides little foothold for dating graves to the Middle Bronze Age B. We therefore have to do solemnly with radiocarbon dates for an inventory of Middle Bronze Age B graves. Fortunately, a catalogue of all radiocarbon dates from the Netherlands was recently published by Lanting & Van der Plicht (2003), which includes a reasonable amount of Middle Bronze Age B dates. This catalogue will provide the main source for my inventory. 3.2.2 Dating Late Bronze Age Graves Like in the Middle Bronze Age metal artefacts are scarce in burials in the Late Bronze Age, so again typo-chronological developments of surrounding feature type and pottery are the main means for dating urnfield graves. As explained in chapter one, the urnfield period in the Netherlands comprises both the Late Bronze Age (1050-800 BC) and the Early Iron Age (800-500 BC). Throughout this period burials were surrounded by different kinds of features (Hessing & Kooi 2005, 637-9). In the Late Bronze Age two types of surrounding features were created: closed circular ditches and both interrupted and uninterrupted oblong ditches (the so-called ‘long beds’ or langbedden in Dutch). In the 37 Early Iron Age the same features are created, plus interrupted ring ditches and, at the end of the Early Iron Age and beginning of the Middle Iron Age, rectangular and square ditches. So unfortunately, no surrounding feature type is typical for the Late Bronze Age and therefore these features do not provide a means for distinguishing Late Bronze Age burials from Early Iron Age ones. Let us see whether pottery provides a better means for dating urnfield burials. Funerary pottery from the Late Bronze Age is much more elaborate and diverse than Middle Bronze Age pottery. In general, this would mean that more handles for dating would be available. However, there are a few problems with the typo-chronological development of Late Bronze pottery. The first problem lies with establishing the typo-chronological sequence. In the classical Urnfield cultures of Switzerland and southwestern Germany pottery is usually dated by typo-chronology of accompanying bronzes. However, as metals are scarce in Dutch burials – from which most pottery comes – this is usually not possible in the Netherlands. The typo-chronological sequence of the Ha A and B pottery of the Northwestern-group – which geographically corresponds to the area between the rivers Rhine, Scheldt and Demer in the north, west and south and the line Hülsten-Gladbeck in the east – as established by Marcel Desittere (1968, 30-60), is therefore mainly based on supposed parallel developments in pottery of the northwestern group and pottery of the classical Rhine-Swiss and Nethermains-Swabian urnfield groups and the groups of the Neuwieder Basin and Neiderrheinische Bucht. Although this works for pottery with clear classical urnfield shapes and elements, it is more difficult to establish the chronological dimensions of the locally derived pot shapes and elements. Also, it is possible that some classical elements might have been in use longer in the northwestern group than in the classical groups. The second problem with the typo-chronology of the Late Bronze Age pottery is the fluent transition from Late Bronze Age to Early Iron Age (Ha B to C) pot types. The new, datable Hallstatt elements in Ha C and D pottery are rather subtle (Desittere 1968, 31). This means that it is often hard to distinguish Late Bronze Age from Early Iron Age pottery. Despite these problems there are several elements that appear to be restricted to the Late Bronze Age. The dating of these elements is based on the typo-chronological sequence as established by Desittere (1968, 30-60). The work of Desittere is the only typo-chronological study of Urnfield pottery from our region. As said, the supposed sequence is mainly based on typological comparison with surrounding and classical urnfield groups and on typological sequencing, as accompanying bronzes are scarce. And although the supposed sequence appears logical and sound, it has, unfortunately, never been verified by radiocarbon dates as is done for the Middle Bronze Age pottery. Lanting & Van der Plicht (2003, fig. 8) have recently published an overview of all radiocarbon dated late Middle Bronze Age to Early Iron Age pottery from the southern Netherlands and some Kerbschnitt decorated pottery from Belgium and Westfalen. Although this contains only a small amount of pots, their dates do all correspond with Desittere’s typo-chronological sequence (except for a pot from Borken-Hoxfeld that is conspicuously young). Desittere’s typo-chronology will therefore be adopted in this study, but it has to be noted that a radiocarbon date based typo-chronology for 38 urnfield pottery from the Meuse-Demer-Scheldt area is long overdue. Besides Desittere, some additional sources for dating stylistic elements will be used. An overview of stylistic elements that are used to single out Late Bronze Age burials is given in table 3.1 and figure 3.1. This list also includes some elements of which a very small number of Iron Age examples are known, but that mainly date to the Late Bronze Age. These are treated as Late Bronze Age elements. This means that our inventory of Late Bronze Age graves may include a few Early Iron Age burials. However, as this inventory is only used to reconstruct general characteristics of burial traditions and material culture and not to study single cases, this approach is warranted or at least necessary, given the scarcity of means to distinguish Late Bronze Age from Early Iron Age burials. Some short comments need to be given on the list of elements. It may be clear that the types of urn that are mentioned here as typical Late Bronze Age types, are only a small selection of the Ha B urn types known. Desittere describes several urn types that are not restricted to the early parts of Ha B (Desittere 1968, 40-5). However, to my opinion, these types are often unusable as a chronological marker, as there appears to be a fluent typological transition from Late Bronze Age to Early Iron Age examples of these urn types. This becomes clear when one, for instance, compares Desittere’s figure VIII, b2 (a Ha B urn type with flaring neck) with some rather a-typical Schhräghalsurnen from the Early Iron Age urnfield of Roermond-Mussenberg (for instance, Schabbink & Tol 2000, fig. 2.15, 18a, 30a or 97a). Also, the general assumption that all cylindrical necked urns date to the Late Bronze Age (Kortlang 1999, 162) does not seem to hold as Ha C/D urns are known with necks that are only slightly flaring or simply cylindrical (for instance, Schrabbink & Tol 2000, fig. 2.15, 42a, 73a, 79a). In addition, some ‘Ha B urn types’ might, according to Desittere, even date to the Early Iron Age (for instance, Desittere 1968, fig. 43, 3 or 51, 4). So it might be that some supposed Ha B urns are, in fact, (a-typical) Ha C/D urns or the other way around. It is therefore decided to only use those urn types that are close to Ha A and early Ha B types as Late Bronze Age markers. The Ha A/early Ha B urn types are close to classical Urnfield culture urn types. Indeed, this resemblance is one of the main criteria for assigning them an early date, besides their association with early types of bronzes and the occurrence of early stylistic elements on them (Desittere 1968). According to Dessitere (1968, 58) many of the classical urnfield culture pot types date Ha A or early Ha B in the northwestern group. There they were quickly transformed to local pot types. Although the chronological aspects of this typological ‘degeneration’ process cannot be precisely determined, due to the scarcity of datable bronzes accompanying pottery, Desittere does hint at a general local development from Ha A/Ha B1 classical urnfield pot types toward Ha C/D pot types. For instance, a development from biconical, sharp-angled cylinder neck urns toward low, broad Schräghalsurne-like pots. One may doubt, however, to what extent the chronological developments of the classical urnfield culture pot types found in the northwestern group run in sync with those of the pot types found in the region of origin. Indeed, recent 14C dates of sharp-angles, biconical pots, a supposed early type, found 39 Element Cylindrical-necked urn with sharp biconical profile (Fig. 3.1.1) Conical-necked urn with lip (Fig. 3.1.2) Conical-necked urn without lip (Randlose Kegelhalsurne) (Fig. 3.1.4) Funnel-necked urn with low shoulder-belly transition (Fig. 3.1.3) Funnel-necked urn with conical part between neck and shoulder (Fig. 3.1.5) Tall cylindrical- or funnelnecked urns with sharp, biconical profiles Coarse ware (Grobkeramik) (Fig. 3.1.6) Shoulder beaker (Schulterbecher) (Fig. 3.1.7) Comment Cylindrical (or slightly flalring) necked, biconical urns with sharp profile of classical urnfield Ha A shape. Some examples can be dated to early Ha B by accompanying classical dekkeldosen or vertical Kerbschnitt rows on the neck. Throughout Ha B these cylindrical-necked urns are supposed to become more rounded and shorter, to end in a low urn with flaring rim, the Schräghalsurne. As the transition between cylindrical-necked urns and Schräghalsurnen is a fluid one and Ha C examples of cylindrical-necked urns are know, only the cylindrical-necked urns that are close in shape to the classical Ha A urns will be treated as typical Late Bronze Age pottery. Desittere mentions several urns with conical neck with lip and high, broad shoulders that can be dated early Ha B on basis of secondary stylistic elements. These urns and derived ones that are close in shape to the them date Ha B. These develop into Ha C pots that are reminiscent of Koberstadt-urns. Biconical or slightly rounded urns with lipless, conical neck, similar to the Randlose Kegelhalsurne known from groups of Nethermain, are pure Ha A shapes. Several derived, more rounded shapes appear to date Ha B. I will treat those urns that are close in shape to the Ha A Randlose Kegelhalsurne as typical Late Bronze Age urn types. Several examples of thin-walled, polished, biconical urns with funnel-neck and low shoulderbelly transition can be dated early Ha B on basis of secondary stylistic elements. These and derived coarser, highly comparable pots will be treated as typical Late Bronze Age pottery. Other kinds of funnel-necked urns are often hard to distinguish from Ha C Schräghalsurnen and Ha C examples of such funnel-necked urns are known. A rare kind of urn with funnel-neck, has a lowlying, conical part between neck and shoulder. On the basis of secondary stylistic elements and several analogues these can be dated (early) Ha B. According to Desittere the tall cylindrical- and funnel-necked urns (those that have a higher height than width) with a sharp, biconical profile date Ha B. Eventually these develop into more pear-shaped Ha C/D shapes. A kind of local coarse ware that is derived from the Grobkeramik of the classical urnfield culture. Two types can be found in the northwestern group: those that are close to the classical types in shape and decoration and a more derived type. Both date predominantly to Ha B. This coarse ware is still in use in Ha C, when it gains a more s-shaped profile and comes to resemble pottery in Harpstedt-style. Beakers that are closely related to the classical Ha A Schulterbechern from southwest-Germany. For Ha B Desittere discerns 6 other beaker types. Although some of these contain classical urnfield References Desittere 1968, 30-1, 40-2 Desittere 1968, 30-1, 43-4 Desittere 1968, 44-5 Desittere 1968, 42-3 Desittere 1968, 42-3 Desittere 1968, 42-3 Desittere 1967; Desittere 1968, 38-9 Desittere 1968, 30-1, 34-6 40 Classical urn-like beakers Beaker or dish with ear (Henkeltöpfe or Henkeltasse) (Fig. 3.1.9) Bowls of type Vogt XII (Fig. 3.1.8) Kerbschnitt decoration (Fig. 3.1.2 & 8) Hatched triangle decoration (Fig. 3.1.3) examples, none appear to be restricted to Ha B, especially the locally derived shapes. So only the Schulterbechern can be treated as a Late Bronze Age pottery type. Beakers that are closely related to the classical Ha A beakers from southwest-Germany that resemble contemporary urns. Beakers or dishes with biconical profile, a short flaring rim and band-shaped ear that resemble southwest German and Swiss types. Two types occur in the northwestern group: beakers without decoration and those with decoration. Of the former both Late Bronze Age and Iron Age examples are known, at least from settlement contexts. Only undecorated bowls and beakers with an ear that originated below the rim appear to be typical Late Bronze Age, according Van den Broeke. The decorated Henkeltasse appears to predominantly date Ha B on basis of associated finds. Desittere mentions only one late Ha B/early Ha C example from Bergeijk-Wilreit which has what appears to be an early Kalenderberg-like kind of decoration. However, this is not Kalenderberg decoration yet and, according to Van den Broeke, Kalenderberg was already present in the assemblage of the 9th century BC site Wychen-De Berendonk. So this might very well be a Ha B beaker. From neighbouring areas Early Iron Age Henktöpfen or Henkeltassen are also scarce, except for Niedersachsen where eared beakers in Early Iron Age Nienburger Tradition are known. So for the northwestern group I will treat the decorated eared beakers and dishes and the undecorated examples with an ear originating below the rim as typical for the Late Bronze Age. A type of bowl that strongly resembles Swiss bowls that are discussed by E. Vogt under row XII. In the northwestern group this type of bowl can be dated to Ha B by associated ceramics and bronzes. The defining element of the northwestern group. Desittere defines this type of decoration as impressed or cut-out triangles. Dates to Ha B in our region. A motive consisting of vertical rows of triangles accompanied by vertical carved lines dates early Ha B. According to Desittere hatched triangle decoration is one of the types of decoration that are contemporaneous to Ha B kerbschnitt decoration, but that continue into Ha C. However, he does not mention specific examples of Ha C/D pottery with hatched triangle decoration. The only examples known to me are of deckeldosen with this kind of decoration, which predominantly date Ha B in the northwestern group but of which also some possible younger examples are known. From the Iron Age urnfield of Beegden two Schräghals urns with a derived example of hatched triangle decoration are known. In the southern urnfield groups, like those of the Niederrheinischen Bucht Desittere 1968, 30-1 Desittere 1967; Desittere 1968, 37-8; Van den Broeke 1991, 199, 206; Verlinde 1987, 255-6 Desittere 1968, 33-4; Vogt 1930, 65-6 Desittere 1968, 45-50 Desittere 1968, 49-50; Roymans 1999, fig. 5.8 & 5.17; Verwers 1966, 42; Van der Sanden 1981, 324; Ruppel 1990, 12-59, 106113 41 Pendant arch decoration (Fig. 3.1.2) Herringbone decoration (Fig. 3.1.1) Symmetrical meander decoration (Fig. 3.1.3) Vertical grooves on shoulder (Fig. 3.1.5) Widely-spaced parallel, horizontal engraved lines (Fig. 3.1.3) Cordon with impressions on neck-shoulder transition Multiple rows of impressions on wall Nail impressions on rim Impressions on outside of rim Wavy rim and the Neuwieder Basin as discussed by Ruppel, hatched triangle decoration appears to be a Ha A/B phenomenon. So, like Verwers and Van der Sanden, I will treat hatched triangle decoration as a typical Late Bronze Age element, as it appears to predominantly date to this period. According to Desittere pendant arch decoration is one of the types of decoration that are contemporaneous to Ha B kerbschnitt decoration, but that continue into Ha C. However, he does not mention specific examples of Ha C/D pottery with this type of decoration. No examples are known to me. So, like Van der Sanden, I will treat decoration consisting of one or multiple pendant arches as typical for the Late Bronze Age. According to Desittere herringbone decoration possibly dates early Ha B, as it does in Switzerland and Southern Germand. As no Early Iron Age examples are known to me, I will treat this kind of decoration as typical for the Late Bronze Age. According to Gersbach a symmetrical meandershaped line-decoration is typical for early Ha B in Switzerland and south-western Germany. In accordance, Desittere assigns a similar date to such decoration in the north-western group. This seems to be confirmed by stylistic elements with which it is accompanied on pots and by finds with which pots with this type of decoration are associated. Decoration consisting of vertical or slanting grooves (Kanneluren), sometimes accompanied by horizontal groovelines at the top (in tradition of the so-called leicht geriefte Waren). In the northwestern group this type of decoration has been found on several early Ha B urns. In more southern groups, like those of the Niederrheinischen Bucht and the Neuwied basin, similar decoration seems to be typical for Ha A. A type of decoration that according to Desittere has only been found on early Ha B pots. In his discussion of pottery from Late Bronze Age settlements of the southern Netherland, Van den Broeke notes that a cordon with fingernail or –tip impressions applied at the neck-shoulder transition is absent in Early Iron Age. In his discussion of pottery from Late Bronze Age settlements of the southern Netherlands, Van den Broeke notes that pottery with multiple horizontal rows of nail or fingertip impressions is absent in the Early Iron Age. In his discussion of pottery from Late Bronze Age settlements of the southern Netherland, Van den Broeke notes that pottery with nail impressions on the rim is absent in the Early Iron Age. In his discussion of pottery from Late Bronze Age settlements of the southern Netherland, Van den Broeke notes that impressions on the outside of the rim – a Middle Bronze Age tradition – are scarce in the Early Iron Age. In his discussion of pottery from Late Bronze Age Desittere 1968, 49-50; Van der Sanden 1981, 324 Desittere 1968, 37. Desittere 1968, 13, 30-50; Gersbach 1951 Desittere 1968, 42; Ruppel 1990, 13-27, 106-9 Desittere 1968, 42-3 Van den Broeke 1991, 207 Van den Broeke 1991, 207 Van den Broeke 1991, 207 Van den Broeke 1991, 207 Van den Broeke 1991, 207 42 Rim with structured lip (Fig. 3.1.2 & 3) Sharp offset at shoulderneck transition Thin walled pottery settlements of the southern Netherland, Van den Broeke notes that pottery with wavy rims is scarce in this period and absent in the Early Iron Age. According to Gersbach rims with a lip that has a structured profile on the inside are typical for early Ha B in Switzerland and south-western Germany. In accordance, Desittere assigns it a similar date for these rims from the north-western group. This dating seems to be confirmed by stylistic elements with which it is accompanied on pots and by finds with which pots with such a rim are accompanied. In their discussion of pottery from Late Bronze Age settlements of the southern Netherland, Arnoldussen and Ball mention a sharp offset at the shoulder-neck transition as typical for the Late Bronze Age. In his discussion of pottery from Late Bronze Age settlements of the southern Netherland, Van den Broeke notes that the average wall thickness of pottery from the discussed Late Bronze Age complexes is 0,7-0,8 mm. Such thin walled pottery is absent from the Early Iron Age, only to be found again amongst the Middle Iron Age Marne type pottery. Desittere 1968, 13, 30-50; Gersbach 1951 Arnoldussen & Ball 2007, 196 Van den Broeke 1991, 206 Table 3. 1 Overview of stylistic pottery elements characteristic for the Late Bronze Age. 43 Fig. 3. 1 Examples of stylistic pottery elements characteristic for the Late Bronze Age. (After Desittere 1968). 44 in western-Belgium show that this pot type also occurs in later parts of the Late Bronze Age (De Mulder et al. 2007, 508). Nonetheless, for now these classical pot types do seem to be restricted to the Late Bronze Age and I think it is safe to assume that, if there is indeed a local typological ‘degeneration’ process with (at least a weak) a chronological aspect, an extensive Iron Age occurrence of such types is unlikely. The classical urnfield culture pot types (and those that are typologically very close to them) are therefore treated as Late Bronze Age markers. Two types of pottery that are perhaps consipicuously lacking from this overview are the undecorated Henkeltassen and the (hals)doppelkoni. In several publication Verwers dates these types of pottery to the Late Bronze Age (Brunsting & Verwers 1975, 67; Verwers 1966, 42; Verwers 1975, 26). Desittere (1968), however, leaves biconical pottery un-discussed and does not state that undecorated Henkeltassen are not produced in the Early Iron Age (Desittere 1968, 37). In fact, in neighbouring areas doppelkoni are known from the Early Iron Age (see Verlinde 1987, 236-7, 250-1), while Van den Broeke notes that undecorated Henkeltassen are known from Early Iron Age settlement complexes. Only undecorated bowls and beakers with an ear that originates below the rim seems to be a predominantly Late Bronze Age pot type (Van den Broeke 1991, 206). Another type of pot dated to the Late Bronze Age by Verwers are amphora. On the basis of northern analogues he assigns an Ha B date to amphora from the urnfield of Goirle-Hoogeind (Verwers 1966, 42). However, Desittere (1968, 45) suspects a southern influence on the amphora from the southern Netherlands and a survival here of amphora into the Early Iron Age. Van den Broeke (1991, 206), on the other hand, notes that amphora, other than tall, slicked examples, are unknown from Early Iron Agge settlements. This makes a Late Bronze Age date likely, but it might be that amphora are exclusively funerary pottery in the Early Iron Age. To play it safe, I will therefore use the ground shape of the pots to date amphora, as suggested by Desittere. The overview contains several elements that are typical for Late Bronze Age pottery from settlements. Some of these elements, although absent from Early Iron Age settlement complexes, may be present on pottery from Early Iron Age funerary contexts. However, as I do not know any Iron Age examples of these elements I will also use them to date urnfield pottery. Van den Broeke (1987) himself suggests that typo-chronological schemes constructed on the basis of settlement complexes can indeed be used to date urnfield pottery. He does note, however, that such schemes often describe the chronological characteristics of complexes of pottery, not single finds. Such characteristics comprise not chronological changes in the nature of technical or stylistic elements, but changes in their relative frequencies. Yet, his scheme for Late Bronze Age settlement pottery (Van der Broeke 1991) contains several elements that are not just present in low frequencies in the Early Iron Age, but are nearly absent. Such elements can be used to date single finds or small complexes to the Late Bronze Age. So, all in all, it is clear that some uncertainties exist concerning urnfield pottery typochronology. To restrict the consequences of these uncertainties for the database of Late Bronze Age 45 burials, it has been decided to score the reliability of dates assigned to the pottery. A score of 1 is given to those pots that are dated by style elements that are Late Bronze Age markers in settlement contexts. Also, the Ha B urn types that are not of a classical Ha A/early Ha B shape and fall outside the regular variation of Ha C/D urn types are scored 1. A score of 2 is given to those pots that are dated by all other mentioned stylistic elements. A score of 3 is given to those pots that display more than one of these elements. Besides typo-chronology of pottery, radiocarbon has also provided several dates for Late Bronze Age burials. These radiocarbon dates have been inventoried by Lanting & Van der Plicht (2003) and will, of course, be used in the current study. A few burials have been dated by accompanying bronzes (see Fontijn 2002, appendix 7.3 for an overview). 3.2.3 Dataset: Organization, Characteristics and Limitations All burial ritual related activities that could be dated to Hallstatt A and B (1200-800 cal BC) by the methods described above were collected in a MS Access database. The highest level record type in this database is not, as the above discussion might suggest, a grave. Instead the more general term ‘context’ is used, which might be a flat grave, a barrow, or an unspecified grave type. These are all phenomena known from Dutch urnfields. Per context the number of graves, individuals and objects and their nature are described. Data for the compilation of the database was retrieved through an extensive survey of published sources. In total the database contains 96 contexts at which evidence for Late Bronze Age activities were recorded. These activities consist either of primary burials underneath a new mound, secondary burials in an existing mound, or instances of Late Bronze Age artefacts or charcoal found in or at surrounding features. Several remarks on the dating of barrows and mound periods need to be made. In general, the date of erection of a mound period is obtained by dating its primary burial. However, to establish the order of burial in barrow (primary vs. secondary) requires the presence of mound body so that the stratigraphical order of burials can be determined. Unfortunately, this is a requirement which is not met for most urnfield barrows. Many barrows have been levelled before excavation. Those that were not, were mostly excavated pre-WOII and – as a result of a cultural-historical framework – published with a main focus on the typology of pottery, thereby leaving out information on barrow stratigraphy. A rule of thumb has therefore been maintained for the dating of barrows: in case of a single burial at the centre of a surrounding feature, this burial is treated as the primary burial of the first mound period. In the case of long barrows, burials on the long axis have been denoted as primary burials. Of all other, off-centre burials the order has been denoted as ‘unknown order’ of ‘unknown mound period’. The supposed primary burials date the barrow in general. Off-centre Late Bronze Age burials provide a terminus ante quem date: in the case of ring ditches they date the mound period Middle Bronze Age-Late Bronze Age and in the case of long barrows they date the mound period 46 Middle Bronze Age B-Late Bronze Age. Finds and charcoal from surrounding ditches also provide a terminus ante quem date for barrows. Here it is assumed that these ditches have not been open for longer than 100-150 years, as signs of reopening a ditch have never been recorded. So, for instance, a Late Bronze Age pot (dating 1050-800 calBC) from a surrounding ditch, dates the corresponding mound period between 1200 and 800 calBC. Small amounts of charcoal or small artefact fragments need not have been deposited in the ditch intentionally, but might have been objects lingering on the surface that ended up in the ditch during the digging of the feature or after the ditch filled up. These do therefore not provide a terminus ante quem date. In total 96 contexts were inventoried from 23 sites. This number of sites is lower than the number of Late Bronze Age burials inventoried by, for instance, Fokke Gerritsen (2001, appendix 2). There are two reasons for this lower number. Firstly, my database only contains burials with contextual information (information on burial structures, association of finds, etc.), while Gerritsen's database also contains many sites of which it is only known that Late Bronze Age pottery was found. Secondly, the criteria used in this study for dating pottery to the Late Bronze Age are probably stricter than those used by other scholars, resulting in a lower amount of burial that can be securely dated to this period. From these 96 contexts, 29 barrows and 49 burials could be securely dated to the period 1050800 BC. This is, of course, a rather small dataset. In paragraph 5.5 it is estimated that the total population of the southern Netherlands in the Late Bronze Age ranges between 595 and 2975 persosns. This would have resulted in several thousand burials, of which our database only contains 49. Such a small sample of course has several limitations. First of all, it will probably not contain the total variation existing in burial rituals. This simply means that the absence of evidence is not the evidence of absence. By taken into account undated phenomena from urnfields I will try to grasp the variation in burial rituals that might have existed. The second limitation – which is one of small samples in general – is that patterns in the relative frequency of phenomena (for instance, of different kind of burial monument shapes) are often not statistically significant. And the last problem, concerns not so much the size of the sample, but rather its nature. As almost all burials are dated by pottery, it is a biased sample. The dataset almost only contains burials with pottery. Despite these limitations, the dataset can give a general impression of the Late Bronze Age burial rituals, as we will see in the next paragraph. 3.3 Patterns of Inception Having explained how the dataset of urnfield burials was composed, it is time to discuss the characteristics of this dataset. From the Middle Bronze Age to the Late Bronze Age several changes occurred in burial practices. There were changes in burial method, burial and monument forms, and ceramic and metal grave goods. In the following the characteristics of these components shall be discussed for both the Middle Bronze Age and the subsequent Late Bronze Age. This way, an 47 overview shall be created of how, when and where the urnfield phenomenon was introduced in the southern Netherlands. It must be noted, however, that the description of Middle Bronze Age burial practices will be mainly a description of barrow burials. As barrows contain only a small selection of the population (Theunissen 1993, 40), there must have been other kinds of burials that are archaeologically invisible. It might be that the urnfield rituals have more in common with these unknown kinds of burials. However, I believe that a comparison between barrow and urnfield burial rites is warranted for as it is a comparison of likes with likes: they are both burials underneath a barrow. 3.3.1 Burial Monuments One of the most salient features of the Dutch urnfields is the diversity in burial monument forms. Throughout the Late Bronze Age and Early Iron Age many small barrows were erected surrounded by closed ring ditches, open ring ditches, post circles, oval ditches, rectangular ditches or square ditches of different sizes. In this paragraph I will describe the monument shapes that were constructed in the Late Bronze Age. However, I will start by giving a characterization of Middle Bronze Age burial monuments, with a special focus on the Middle Bronze Age B. The most prominent kind of burial monument erected in the Middle Bronze Age of the Southern Netherlands, and of most parts of north-western Europe, is the round barrow. The first round barrows appear in the Southern Netherlands at the beginning of the Late Neolithic (2900-2000 BC) and will be erected until historical times. Through time changes occurred in shape, size, surrounding feature type and burial forms of these round mounds. An overview of the characteristics of Late Neolithic and Middle Bronze Age barrows of the Southern Netherlands has been given by Liesbeth Theunissen (1999). A short recapitulation of her characterization of Middle Bronze Age barrows shall be given here, with additional information on the burial monuments of the Middle Bronze Age B. At forehand an important remark needs to be made, however. Radiocarbon dates for round barrows are scarce and only a few mounds have primary burials containing grave goods that let a barrow be dated to a specific sub-period of the Bronze Age. For this reason, typo-chronology of surrounding features has been the main means for Theunissen to date round barrows (Theunissen 1999, 54-7). However, as said earlier, Bourgeois has recently found that the different types of surrounding features (including the featureless barrow) are roughly contemporary and that almost all barrows fall within Middle Bronze Age A and the first quarter of Middle Bronze Age B (Bourgeois & Arnoldussen 2006; Bourgeois in prep.). Theunissen’s subdivision between Middle Bronze Age A and B barrows is therefore not one of round mounds from two different periods, but mainly one of two different types of Middle Bronze Age barrows: those without and those with post circles. Some types of post circles do appear to come in use slightly later than other kinds of surrounding features (post circle type 6-8 date between 16001400 cal BC; Bourgeois in prep.), though. So the differences in burial ritual between the Middle 48 Bronze Age A and B noted by Theunissen may have some chronological significance, but to what extent is unknown. Also, they are not differences between the Middle Bronze Age A and B, but rather between the beginning and the end of the Middle Bronze Age A. Theunissen’s main unit of recording is not a barrow, but a mound period: a phase of barrow expansion or reconfiguration. Throughout the Middle Bronze Age, mound periods with different kinds of surrounding features have been erected: those with ring ditches, post circles or bank and ditch (ringwalheuvels). Thirty Bronze Age mound periods without surrounding features are known. Barrows with bank and ditch appear to date to the Early Bronze Age and the Middle Bronze Age A. They come in different forms, with different configurations of bank and barrow. With only seventeen known examples they are a rather rare phenomenon, which – except for one northern example – appears to be restricted to the southern Netherlands and the southern parts of Europe in general. A more general occurrence are barrow periods with a surrounding ring ditch (N=57). During the Middle Bronze Age the ditches were dug at the foot of the mound. Their diameter varies between 5 and 19 m, with an average of 11,3 m. A small group (N=7) has an opening at the east side. The barrows with a surrounding post circle make up the largest group burial monuments. With 101 known examples they constitute nearly half of all barrows. For the post circles of the southern Netherlands a typology has been posed by Glasbergen (1954b). In total he discerned 9 types of post circles (fig. 3.2), of which the single, widely spaced post circle (type 3), the circle of widely spaced paired posts (type 4), the single, closely spaced post circle (type 5), the double, closely spaced post circle (type 6), the triple, closely spaced post circle (type 7), the quadruple and multiple post circle (type 8) and the circle of close-set stakes (type 9) have been constructed around Middle Bronze Age mound periods. Circles of stakes are sometimes found in combination with other types of post circles (N=4) and sometimes as a temporary construction around a burial pit. The diameter of these post circles ranges between 4 and 40 m, with an average of 10,3 m. The moment of their construction and their appearance remain points of debate. The symmetry of some post circles and the presence of small heaps of sand beneath the foot of some barrows suggest that at least some post circles were erected before the building of the mound. Most of the post holes are round and are on average 40 cm (type 3) or 60 cm (type 6-8) deep, indicative of posts with varying heights. Postholes (paalschaduw) have a diameter between 20 and 25 cm. Some scholars suggest that the posts of type 3 and 4 features would have been connected by cross-beams, after the example of English trilithons found at hengemonuments. However, the construction of post circles seems to be a tradition that was mainly practiced on the Pleistocene sandy areas of the Netherlands and western Germany. A unique type of post circle appears to be the circle of single, widely spaced paired posts, which seems to be limited to south-eastern Noord-Brabant and the Belgian Kemps. 49 Fig. 3. 2 Post circle types defined by W. Glasbergen. (Theunissen 1999, afb. 3.8) For the Early and Middle Bronze Age, Theunissen has recorded a total of 220 barrow periods. However, these mound periods are not evenly distributed over the different sub-periods of the Bronze Age. She discerns a diachronic patterning in which there is an increase through time in the number of mound periods being erected. Apparently the round mound as the burial monument of choice increased in popularity, peaking in the Middle Bronze Age B. But, as said earlier, the dating of most mound periods by Theunissen is based on an erroneous typological argument. In fact, Bourgeois and Arnoldussen (2006) have recently shown that of the 103 Dutch barrows with a secure radiocarbon date, only 4,3 % date younger than 1400 cal BC. So, the peak in barrow periods observed by Theunissen did not take place in the Middle Bronze Age B but the preceding Middle Bronze Age A. So, the most salient aspect of Middle Bronze Age B burial monuments seems to be their almost absence. But what kind of burial monuments were built then after 1400 BC? As explained above, radiocarbon dating is the only means to securely date barrows to the Middle Bronze Age B as there are no surrounding feature or grave good types characteristic for this period. Table 3.2 gives an overview of the small group of barrows that might date to the Middle Bronze B. Amongst these are of course the well-known round barrows surrounded by post circle or ditch, perhaps a featureless mound and possibly even a late example of a barrow with bank and ditch. Notable, however, is the presence of several monuments with a rather unusual shape (fig. 3.3). From the burial ground at Kamps Veld near Haps a keyhole-shaped monument was found – monument O3 – which was surrounded by a double row of closely spaced posts. Keyhole-shaped monuments are wellknown from urnfields in the Northern Netherlands, but are unknown in the southern Netherlands except for an undatable monument from the Early Iron Age urnfield at Beegden (Roymans 1999). 50 Toterfout-Halve Mijl Toterfout-Halve Mijl Secondary name Tum. 1 Tum. 5 Toterfout-Halve Mijl Tum. 15 Toterfout-Halve Mijl Tum. 19 Toterfout-Halve Mijl Toterfout-Halve Mijl Tum. 18 Tum. 16 Toterfout-Halve Mijl Toterfout-Halve Mijl Tum. 2 Tum. 17 Haps-Kamps Veld H4 Haps-Kamps Veld O1 Haps-Kamps Veld Toterfout-Halve Mijl O3 Tum. 8 Toterfout-Halve Mijl Tum. 12 Knegsel-Knegselse Hei Tum.

Those burials with no values for shape and surrounding feature are flatgraves. 52 However, unlike the northern examples the monument at Haps does not have a short, trapeziumshaped ‘beard’ but an elongated, oval one. Therefore this monument resembles more the other kind of unusual shapes found amongst the Middle Bronze Age B barrows, the oblong monuments. Such an oblong monument was found at Toterfout-Halve Mijl near Veldhoven, where barrow 2 was surrounded by a ring ditch which was slightly ellipse-shaped. Monument O1 found at Haps-Kamps Veld has a more prominent oblong shape: the first period of this monument consists of a rectangular double row of closely spaced posts, which was at a later, unknown date extended along its long axis. At Veldhoven-De Heibloem another two irregular, rectangular monuments were found, both surrounded by a ditch. The monuments were built next to each other and were later covered by a single round mound with a burial at its centre. The chronology of this complex monument is, however, hard to establish, due to many large-scale disturbances. From a sand pit dug through the monument came two cremations which were 14C dated and provide at least a Middle Bronze Age B terminus ante quem date for one of the rectangular monuments. From the Belgian part of the Meuse-Demer-Scheldt region comes a further example of an oblong monument dated to the second half of the Middle Bronze Age B (Delaruelle et al. 2008; fig 3.3.1). At Beerse-Mezenstraat a monument was found that is surrounded by both a ditch and a triple post setting. At the burial ground of Oss-Zevenbergen another oblong monument was found surrounded by both a post setting and a ditch (fig. 3.3.3). However, here the surrounding features are not contemporary – the post setting belongs to the first period of the monument, which dates either to the Middle Bronze Age B or the Late Bronze Age (Valentijn in prep.). At Late Bronze Age and Early Iron Age urnfields oblong monuments are a well-know phenomenon. In fact, Verwers (1966b) has developed a typology for monuments with elongated surrounding ditches. He discerns two types: the Riethoven and the Goirle type. The former comprises a group of short and wide monuments with an average length of 15,6m and a width of 5,5m. The monuments have a length:width index ranging between 2 and 4. These monuments mostly occur as isolated, single monuments. The latter type consists of long and small monuments. All monuments of this type are longer than 30m, with an average length of 42m. Their width averages on 3,8m. Except for one, none of the monuments of this type has an index between 4 and 8. Recently Kortlang (1999) has defined a third type, the Someren-type longbed, in which the short sides of the surrounding ditch is missing. This type seems to be restricted to the Early Iron Age. The above mentioned Middle Bronze Age examples of oblong monuments are all of the Riethoven kind. However, most differ from the urnfield examples of Riethoven-type monuments in that they are surrounded by posts – something which seems to be rare in Late Bronze Age urnfields (see below). Also, the Middle Bronze Age long barrows are of an unusual or irregular shape (HapsKamps Veld O1 and O3). For the unusual key-hole shaped monument from Haps, only one analogue is known. A similar shaped monument was found at the Late Bronze Age/Early Iron Age urnfield of Valkenswaard-Het Gegraaf, this time surrounded by a ditch (Brunsting & Verwers 1975). The authors 53 Fig. 3. 3 Overview of unusually shaped Middle Bronze Age B barrows. 1: Beerse-Mezenstraat (Delaruelle et al. 2008, fig. 3); 2: Toterfout-Halve Mijl, mon. 2 (Glasbergen 1954, fig. 10); 3.

Veldhoven-Heibloem, mon. 100 (Modderman & Louwe Kooijmans 1966, fig. 4). 54 date this monument to Ha B by pottery from the surrounding ditch. However, I do not agree with this dating as this pottery does not display any of the Ha A/B elements summed up in paragraph 3.2.2. So, only the oblong monuments from Veldhoven-De Heibloem seem to be of a typical Riethovenmonument shape. However, these monuments are associated, while the later Riethoven monuments are characterized by an isolated occurrence. One example of a system of Riethoven type monuments is known, though, from the Late Bronze Age urnfield at the Knegselsche Hei near Knegsel (Braat 1936). So, with the Middle Bronze Age Riethoven monuments we seem to have a predecessor to the urnfield long barrows, although they appear to be of an atypical kind.

For this period I have inventoried a mere 29 burial monuments from 23 sites of which a burial at its centre or on its long axis could be dated to this period (table 3.3 & table 3.4). Another 16 could be terminus ante quem dated to the period 1500-800 BC (table 3.4). As probably almost none of these will pre-date 55 1325 cal BC or M. Br. D – the urnfield period in Europe at large – they will also be taken into consideration here. Of the 29 Late Bronze Age burial monuments 7 were long barrows (table 3.5). Another 7 date between the period 1500-800 cal BC. Of these 12 are of the Goirle type, while only 2 are of the Riethoven type. This does not mean, however, that the Riethoven type is a rare phenomenon at Late Bronze Age urnfields. At 9 of the 12 sites of which a substantial area was excavated (and published with map) and which contained Late Bronze Age burial monuments, monuments of the Riethoven type were found which could not be dated . What is more, at the urnfield of Knegsel-Knegselsche Hei at least 8 long barrows of the Riethoven type were found, while at this urnfield the only datable burials date to the Late Bronze Age. Long barrows of the Goirle type are found at 6 sites. Of these, 4 sites also contained Riethoven monuments. Of the long barrows of which the shape could be determined, 9 had an oval shape, while one was rectangular with rounded edges. The width of the long barrows ranges between 3,0-6,4 m, and their length between 15,9-77,8 m. All datable examples were surrounded by ditches. Only at the urnfield at Knegsel-Knegselsche Hei a long barrow with both surrounding ditch and post-setting was found, which unfortunately could not be dated. Culture 1050-800 BC 1500-800 BC 1800-800 BC Site type Barrow Flat grave Possible flat grave Possible grave Grave unspecified Barrow Flat grave Grave unspecified Barrow Count 29 11 9 5 5 17 3 1 8 Table 3.2 Number of inventoried examples per site type The most common shape at Late Bronze Age urnfields is the round barrow. In total 22 examples could be dated to period 1050-800 cal BC, while another 9 could be dated between 1200800 cal BC. Eight examples of round mounds with off-centre Late Bronze Age burials were dated to the period 1800-800 cal BC, but probably date to the Late Bronze Age or the period immediately preceding it. Not only in the inventory, but also in all excavated urnfields round barrows dominate. However, at some urnfields long barrows do make up a large part of the urnfield (Hilvarenbeek-Laag Spul; Goirle-Hoogeind; Veldhoven-De Heibloem). Every one of the Late Bronze Age round barrows was surrounded by a ring ditch and all the completely excavated ring ditches were closed, except for one equivocally dated ditch with an opening to the northwest. The diameter of the round barrows ranges between 4-8m, with an average of 5,9m. Some Late Bronze Age round barrows might have been slightly bigger than this, as from several urnfields with signs of Late Bronze Age activity a few undated barrows with a diameter a little over 10 m are known. 56 Culture 1050-800 BC 1500-800 BC Long barrow type Goirle Riethoven Goirle 1 - 2 3 2 2 3 2 5 Total 5 2 7 Table 3.3 Number of long barrows per type. The numbers 1 to 3 indicate the reliability of dating (see paragraph 3.2.2). Like the long barrows, none of the datable round mounds were surrounded by a post setting. In fact, only at two urnfields with Late Bronze Age burials post settings have been found. At GoirleHoogeind a barrow with surrounding post-circle was found, which can be dated to the Middle Bronze Age (Verwers 1966, 36). In the urnfield at the Knegselsche Hei three round barrows with post circle and a long barrow with ditch and inner post setting were found. None of these could be dated, but a Middle Bronze Age date is likely. Early Iron Age examples of post settings are known from the Muese-Demer-Scheldt area, for instance from a round barrow from the Early Iron Age urnfield at Mierlo-Hout (Tol 1999) and two long barrows with surrounding post setting from the Belgian site Neerpelt-De Roosen (Roosens & Beex 1962). A continuing of the building of post-settings in the Late Bronze Age can therefore be assumed, but on a far smaller scale than in the preceding Middle Bronze Age. In closing, I shortly want to discuss those graves that were not covered by a monument: the flat graves. Only five locations with flat graves are known from the Middle Bronze Age (Theunissen 1999, 73). This low number is probably the result of the small scale of past barrow research, which was limited to the excavation of the mound body proper and not its surroundings. Of urnfields a larger part of the surrounding was usually excavated, often the entire urnfield. Not surprising, the more flat graves are known from the Late Bronze Age then the preceding Middle Bronze Age. In total 14 flat graves are known, 11 dating to 1050-800 cal BC and 3 dating to 1500-800 cal BC (table 3.4). Some of these may actually be burials from levelled barrows without a surrounding structure, as they are often found in between ring ditches. Unfortunately, this can no longer be ascertained. 3.3.2 Burial Practices In the previous paragraph we discussed the types of burial monuments constructed during the Middle and Late Bronze Age. Now we will take a look at the manner in which the deceased were interred in these monuments. The fact that the deceased were cremated in both the Middle and Late Bronze Age has been put forward by Verwers (1971) as an important indication that the transition between the two periods was not associated with radical changes. Verwers has, however, paid little attention to the manner in which the cremated remains of the deceased were interred in the two periods, other than the ratio of urn to non-urn burials. Making use of Theunissen’s (1999, 78-86) overview of Middle Bronze Age burial practices and the inventory of Late Bronze Age burials, I will give a more exhaustive overview of burial practices of the Middle and Late Bronze Age. 57 For the Early and Middle Bronze Age Theunissen has recorded a total of 304 burials, of which 149 were located centrally under a mound period and another 158 were secondary.2 Amongst these were three types of interments: inhumation, cremation and cremation in an urn. These were either placed on the old surface, in an oval or round pit, in a burial pit (rectangular and twice as long as wide), in a treecoffin, between tree logs, in a stone niche, or in posthole of a surrounding post circle. Dominant are the cremation burials: 71 primary burials and 143 secondary burials. This against 55 inhumation burials, of which 43 central burials and 12 secondary burials. According to Theunissen inhumation burial is practiced less and less through time from the Late Neolithic onwards. But, as explained in paragraph 3.2.1, her dating of barrows is based on faulty typological arguments. If we combine the numbers she gives for Middle Bronze Age A and B burials (Theunissen 1999, table 3.11) it is clear that inhumation burial (N=47) was less often practiced during the Middle Bronze Age than the burial of cremated remains (N=176). Cremation was practiced more than three times as often as inhumation. However, this appears to be mainly the case for secondary burials: from the Middle Bronze Age in total 49 primary cremation burials are known against 36 inhumation burials – less than 1,5 times as many – but only 11 secondary inhumation burials are known against a massive 127 cremation burials – almost twelve times as many! So for secondary burials an obvious preference for cremation burial seems to exist. However, this preference may have been less strong than these numbers suggest. Whereas a cremation burial always leaves clearly discernable remains in the form of cremated bones, inhumation burials are often much more difficult to recognize. As unburned human remains only rarely survive on the sandy soils of the southern Netherlands and only 9,2 % of all Middle Bronze Age burials contain grave gifts other than containers of cremation (Theunissen 1999, 86), it is mainly the outline of a burial pit or tree coffin which make an inhumation burial recognizable. When it comes to burials at the centre of barrow, excavators are often more keen on discerning the remains of a burial, resulting in a more easy discovery of a primary inhumation. In the case of secondary inhumation burials, the remains are more difficult to recognize. First, soil development may have obliterated the traces of a burial. Also, the excavation strategy determines whether a secondary inhumation will or will not be recognized. Only when a barrow has been excavated in horizontal layers, will such a burial be recognized – something which often has not been the case. The true number of secondary inhumations may therefore have been significantly higher. However, in the northern Netherlands over 300 secondary inhumation have been found in about the same number of barrows as known in the southern Netherlands (Lohof 1994), even though the same post-depositional processes have been at work there. So, although the number of secondary inhumations may in reality have been higher, a strong preference for cremation in secondary burials still seem to have existed, but not as strong as Theunissen’s numbers suggest. 2 These are the totals given by Theunissen (1999, 79), but the observant reader will notice that the amount of central and secondary burials combined comes to a total of 307 burials, instead of 304 burials. 58 Inhumation burials are found on the old surface, in burial pits and in tree-coffins. The latter two types are found both as primary and secondary burials, while the former only as a primary burial. Like inhumation burials, cremated remains were also interred in different ways (table 3.6). The numbers that will be given here are the combined numbers of Early and Middle Bronze Age burials, as Theunissen does not give separate numbers for the totals of the two periods. But as only 5 Early Bronze Age burials are known, the combined numbers do not differ much from the Middle Bronze Age totals. Some cremated remains were found on the old surface beneath a barrow. Sixteen primary cremations were found on the old surface beneath barrows (22,5%), against a mere 12 secondary examples (8,4%). Cremated remains in an urn are found in an equal number in primary position (N=16), but notably more often in secondary position (N=55; 38,2%). The number of primary urn burials may originally have been higher, as quite a number of urns were lost to so-called urnendelvers – local people who dug through the centre of barrows in search of urns to sell to museums and other collectors. Almost all of the urn burials were interred in a pit; only a few examples were deposited on the old surface, in a tree coffin, or in a stone chamber. Cremated remains were also interred in a pit without a ceramic container: 9 times as a primary burial (12,7%) and 19 times in secondary position (13,3%). Some of these might date from the urnfield period, though. This group likely contains some archaeologically invisible variation: some remains were probably interred in a decayed organic container, others were interred as a pack without a container, while others were probably just scattered in the burial pit. Sometimes cremated remains were deposited in a burial pit or in a tree-coffin. The former was found 19 times as a primary burial (26,8%) and 9 times as a secondary burial (6,3%). The latter was found 9 times as a primary burial (12,7%) and 22 times as a secondary burial (15,4%). These two types of burials have the appearance of an inhumation burial, but instead cremated human remains were interred. The last variant is the burial of cremated remains in a post hole of a surrounding feature. Twenty-six instances of this type of burial are known (18,2%), of which 7 were found in the surrounding structure of one barrow at Toterfout-Halve Mijl.

(After Theunissen 1999, table 3.9) 59 If we look at these totals and percentages (table 3.6) a view things stand out. For the primary burials two types of interment appear at first sight to have been practiced more often than others: the deposition of cremated remains on the old surface beneath the barrow (22,5%) and deposition in a burial pit (26,8%). The high amount of cremation burials in a burial pit is significant, because it indicates that a reference to inhumation was maintained as such a large pit is unnecessary from a practical point of view. The same probably goes for the tree-coffin burials (12,7%). Apparently, the shape of the pit was determined by considerations other than the type of human remains. Nonetheless, the interment in a pit, both the urn and non-urn burials combined, appears to be largest group of burials (29,6%). The same goes for the secondary burials, but here the pit burials make up almost half of all burials! The majority of these are urn burials, which might be explained by the fact that ceramic containers are more easily recognized. Interestingly, the two types of burials that dominated amongst the primary burials – burials on the old surface and in a burial pit – only form a minor part of the secondary burials. For the burials on the old surface, this is to be expected as it would mean that such a secondary burial needs to happen more or less contemporary with a primary burial, before the construction of a mound period. It is, however, more difficult to explain the low amount of cremations in a burial pit. To a certain extent it might be explained by the manner in which barrows were excavated. Only when a mound is excavated in horizontal levels will a burial pit probably be recognized, contrary to urn burials and burials in small pits which do not need a rather extensive excavation level to be recognized. This pattern might, however, also simply be an archaeological artefact. We already saw that amongst inhumation burials secondary burials are less common (21,8% of all inhumation burials) than amongst cremation burials (66,8%), even if we take into account the secondary inhumation that might not have been recognized during excavation. So, if cremation burials in a burial pit or tree-coffin indeed reference to inhumation burials (or the ideas behind such burials), it is to be expected that there are relatively less secondary burials than primary ones. Just as for inhumation burials.

The numbers 1 to 3 indicate the reliability of dating (see paragraph 3.2.2). 60 Unfortunately, this characterization of burial practices concerns the entire Early and Middle Bronze Age. Although it mainly concerns the period 1800-1400 BC, as only a few Early Bronze Age burials are known and most barrows were built before 1400 BC, this is still quite an extensive period and does not give any detail on the period in which we are most interested, the Middle Bronze Age B. In the previous paragraph we gave an overview of all barrows that might date to the Middle Bronze Age B (table 3.2). When we look at the manner in which the deceased were interred in these mounds, we find almost the entire variety of burial practices known from the Middle Bronze Age as a whole. Cremated remains are placed on the old surface, in a tree coffin, in a burial pit, in an urn, in a pit, and at the bottom of postholes. Cremations in burial pit or tree-coffin are only found in barrows that predate 1400/1350 cal BC, though. The other types seem to have been used the entire period up to the Late Bronze Age. One has to keep in mind, however, that this is only a small sample and that these barrows come mainly from two sites. The variation of burial practices in the period preceding the Late Bronze Age may, therefore, have been larger than suggested by these burials. It is, of course, also a biased sample, as these barrows are mainly dated by (primary) cremation burials. Inhumation may very well have been practiced during this period, but this kind of burial is simply less likely to be included in the sample. So, now that we have characterized the burial practices of the Middle Bronze Age, let us look at the manner in which the deceased were interred during the Late Bronze Age. A problem with a discussion of the burial practices of this period is the lack of information on the interments in published excavation reports. More often than not, nothing is said about the structure in which cremated human remains were deposited. Usually, only information on the accompanying pottery is given – but often it is not even mentioned whether or not this pottery contained the associated cremation. The little information that was available on the interments is collected in the database. In total 49 burials from the period 1050-800 BC were inventoried, and another 11 from the period 1500800 BC. The majority of these were burials in an urn (table 3.7) – this is to be expected, since most burials were dated by accompanying pottery. Verwers (1971, 59-60) has already shown that the percentage of non-urn burials at urnfields with Late Bronze Age burials is, in fact, higher than at those urnfields with Early Iron Age burials: 44% or higher. All urn burials of which it was noted in the excavation report in what kind of structure they were found, were found in a pit (N=8 for the period 1050-800 BC). The same is true for the non-urn burials (N=8). For only four pits the diameter were given in the excavation report, which range between 45 and 60 cm. However, when one looks at the excavation maps of the Late Bronze Age urnfields more or less round, rather small pits seem to be the rule. Oblong pits of the size of inhumation burial pits, as found in the Middle Bronze Age, appear to be absent or at least form only a very minor part of the Late Bronze Age burial practices. 61 Culture 1050-800 BC Position Unspecified Centre Off-centre Between centre-edge Edge 1500-800 BC Surrounding feature Unspecified Centre Off-centre Burial type Container Possible grave Container Non-container Possible grave Container Non-container Container Non-container Possible grave Container Container Container Possible grave Non-container Non-container 1 3 1 2 1 1 1 1 - 2 5 5 6 1 2 1 1 2 2 2 - 3 2 1 4 3 1 1 1 2 1 2 1 Total 2 8 7 10 6 3 2 1 1 3 5 1 1 1 5 1 Table 3.6 Burial type per horizontal position in Late Bronze Age barrows. The numbers 1 to 3 indicate the reliability of dating (see paragraph 3.2.2). Information on the stratigraphical order of burials is often lacking, either because the excavated urnfield barrows were already levelled before excavation or because the information has simply not been published. Only the horizontal position of most burials could be determined, but no apparent patterning seems to exist in the amount of urn vs. non-urn burials at the different locations (table 3.8). Only the amount of non-urn burials at the centre of the barrow seem to be slightly higher than that of de-central urnless burials. Urn burials are found in equal amount in central and de-central position. Of 17 Late Bronze Age burials the amount of cremated remains from the burial has been noted in the excavation reports. Their weight ranges between 49 and 1101 grams, with an average of 557 g (table 3.9). Only one grave contained 1900 g of cremated bones. About the same numbers can be given for 7 burials that date to the period 1500-800 cal BC. The average weight of cremated remains might in reality have been slightly higher as some of the burials with a low amount of bone might be disturbed graves. However, all in all it is clear that for most burials there was no intention to collect all the cremated remains from the pyre. It is hard to say how meticulously the human remains were collected from the pyre debris: both examples of Late Bronze Age burials containing no charcoal (N=2) and lots of charcoal (N=2) are known. For most burials it was not noted in the excavation reports whether the pit contained any charcoal or if it did, how much (N=6). It is hard to compare the manner in which cremated remains were collected in the Late Bronze Age to the way it was done during the Middle Bronze Age, as Theunissen (1999, 91-4) gives little information on this. She only gives the average weight of human remains of the cremation burials from Toterfout-Halve Mijl. This is only slightly higher than the weight of Late Bronze Age cremations – like in the Late Bronze Age, during the Middle Bronze Age not all cremated human remains were collected from the pyre. 62 Town Toponym Sec. name Period Maastricht Maastricht Maastricht Sint-Oedenrode Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Hilvarenbeek Sint-Oedenrode Zundert Zundert Hilvarenbeek Sint-Oedenrode Hilvarenbeek Mook Sint-Oedenrode Maastricht Sint-Oedenrode Withuisveld Withuisveld Withuisveld Haagakkers Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Laag Spul Haagakkers Mencia Sandrode/Akkermolenweg Mencia Sandrode/Akkermolenweg Laag Spul Haagakkers Laag Spul Nieuwbouw Bovensteweg 20 Haagakkers Ambyerveld Haagakkers Findnr. 17 Findnr. 17 Findnr. 15 Grave 62 Findnr. 137 Findnr. 138 Findnr. 112 Findnr. 2 Findnr. 9 Findnr.

Whereas the funerary pottery of the Middle Bronze Age is known by its rather crude appearance and limited variation, the urnfield pottery is generally well/made and displays a broad variety of shapes and decoration motifs. Here I will describe how the earthenware repertoire has changed from the Middle to Late Bronze Age. A description of the general Middle Bronze Age pottery types was already given in paragraph 3.2, so it will suffice to give a short recapitulation here. Glasbergen (1969) has defined three types of pottery for the Middle Bronze Age on the basis of the shape, rim type and decoration of pots. Hilversum pottery (HVS) is characterized by more or less biconical pots, both with and without cord, nail or hollow bone or reed impressions on the collar (triangles, meshes, groups of vertical lines, wavy lines, groups of ovals, or series of circles) and sometimes cord or nail impressions on the rim (triangles, parallel lines, or sometimes a single line). Some Hilversum pots have horseshoe shaped handles. Later HVS pots have a more ‘truncated-pear shape’ (afgeknot peervormig), and are sometimes decorated with cord impressions, but mostly with nail impressions (Glasbergen 1969, 14, 18-9). Drakenstein pots (DKS) are more or less ‘truncated-pear shaped’ or bucket shaped. According to Glasbergen the earliest DKS pottery types have an inward slanting rim, often with a fingertip-decorated cordon (stafband). The later types have rounded rim and perhaps a row of fingertip impressions several centimetres below the rim, if decorated at all (Glasbergen 1969, 19). Laren pottery (LR) is barrel or bucket shaped, mostly undecorated (only sometimes a row of fingertip impressions underneath the rim) (Glasbergen 1969, 27). According to Glasbergen (1969) DKS and LR pottery represented typological devolution from HVS pottery and therefore a chronological development. Radiocarbon dates of HVS, DKS and LR pots have shown, however, that HVS indeed is limited to Middle Bronze Age A, but that DKS and LR pots occur in both Middle Bronze Age A and B (see paragraph 3.2). On the basis of radiocarbon dating some pots might date to the period between 1500 and 1200 cal BC (table 3.10 & fig. 3.4). Interestingly, we do not find any DKS pots amongst these, but only simple bucket-shaped LR-like pottery (cf. Bourgeois in prep.). Even though DKS pottery is known from settlements contexts from this period, it appears that only the LR-like pots have been used as urns during the Middle Bronze Age B. And this type of pot was possibly still used at the beginning of the urnfield period as shown by the examples from Lent-Smitjesland and Sint-Oedenrode-Haagakkers (fig. 3.4.8-10). Notable are the vessels from Haps and Groot-Linden (fig. 3.4.6, 7 & 10) that obviously still retained the high shoulders of the Middle Bronze Age pots, but that differ from them in having a tripartite build-up. Both the transition from belly to shoulder and from shoulder to neck are rather pronounced on these vessels. These unusual shapes all date mainly to the period of the Beginnenden 64 Nr. 1 2 3 Hoge en Lage Mierde Haps Secondary Sample name Tum. C Crem 3 O1 Crem 162 Knegsel Tum.

Numbers correspond to table 3.8. 66 and Älteren Urnenfelderzeit (1300-1000 cal BC) and perhaps display the first signs of influences from the central European urnfield culture, such as the “Urnenfelder-Schrägrand” on the vessels from Haps (cf. Ruppel 1985, 23). The earliest clear central European influences on the pottery from the southern Netherlands can be found on the so-called shoulder beakers, the sharp-angled cylindrical necked urns, the funnel-neck urns with low-lying belly or with conical part between neck and shoulder, and the liplose kegelhalsurnen (fig. 3.1). However, these do not date earlier than the end of Ha A and the beginning of Ha B (cf. Ruppel 1985; Desittere 1968). One may wonder, however, whether no other vessel types were produced during Ha A than the above mentioned a-typical Middle Bronze Age shapes. Every Dutch Late Bronze Age urnfield contains numerous pots which on typological grounds cannot be further assigned to a sub-period of the urnfield period, as they show no affinity with central European pottery types. It might very well be that some of these vessels actually date to the earlier parts of Ha A. For instance, at the Belgian urnfield near Donk a grave was found containing an amphora and beaker which could not be dated on typological grounds. However, these vessels were accompanied by an early Ha A bronze pin (Ruppel 1985, 21-3). From the Ha B period many vessels are known – both vessel types with apparent central European influences and locally derived types. As an extensive characterisation of this pottery has been given by Desittere (1968) I will not discuss them any further here. The main difference between the Late and Middle Bronze Age pottery is the broad range of pottery shapes and the varied decoration found in the Late Bronze Age. A new element in this period is polishing of the vessel and overall the urnfield pottery is substantially thinner. However, the crude finishing that typifies the Middle Bronze Age vessels appears to continue in the rather coarse Grobkeramik. Thus far, I have mainly discussed the typology of Middle and Late Bronze Age pottery. Let us now take a look at how ceramics were deposited in burials during these periods. We already saw that during the Middle Bronze Age cremation burial in an urn was a common phenomenon, especially for secondary burials. However, only two examples are known from this period of pottery from a burial that was not used as an urn (Theunissen 1999, 89). And in this it differs significantly from the Late Bronze Age ceramics from burial contexts. If we look at the location in the grave of the pottery in our database, we see a distinct difference with the Middle Bronze Age pots (table 3.9): more than half of the pottery found in Late Bronze Age burials was not used as an urn. A part of this non-urn pottery is possibly made up by destroyed urns, but even 67 if so the amount is significantly higher than for the Middle Bronze Age pots. And then there is also the large amount of pottery found in surrounding ring ditches. All in all, it appears that not only the types of pots used in Late Bronze Age burial rituals seems to have changed significantly, but also the manner in which they are used.

Both in the Middle and the Late Bronze Age metals were only rarely deposited in burials, while many are known from natural places as rivers, brooks and marshes. In this paragraph I will give a short characterization of the kind of metal artefacts found at burials contexts of the Middle and Late Bronze Age. Of all Early and Middle Bronze Age burials only 13 (4,3%) contain metal artefacts or indications for these. All of these are bronzes: axes (N=2), a chisel (1), a small ring (1), small plates (2), tweezers (1), and several unidentifiable objects (2). Of these, the axes and chisel are exotic, imported items. Besides the bronze items, cremated bones of 7 burials display green staining, indicative of bronzes that have been burned on the pyre alongside the human remains. Notably, all bronze objects were found in primary graves, apparently all unburned. The cremated bones with green staining, on the other hand, were all found in secondary burials (Theunissen 1999, 878). On the basis of 14C-dating and typo-chronology all the bronzes can be dated to the Middle Bronze Age A. No Middle Bronze Age B examples of metal artefacts from graves are known, while in this period the deposition of metals at natural places has increased compared to 68 the preceding periods (Fontijn 2002). From the southern part of the province of Limburg four barrows are known, though, in which bronzes were deposited in the mound body without accompanying human remains (Theunissen 1999, 88). In these barrows were found a dagger, two sickles, a spearhead and three axes, all dating to the Middle Bronze Age B or the beginning of the Late Bronze Age. So, bronzes are known from burial contexts, but apparently as votive deposits rather than grave gifts. During the Late Bronze Age the deposition of metal artefacts in graves occurs more often than in the preceding periods. For the urnfields from the Meuse-Demer-Scheldt area the percentage of graves containing bronzes ranges between 0 and 18%. – still the exception rather than the rule (Fontijn 2002, table 9.1). According to Fontijn (2002, 241) this increase in the number of graves with metals need not be significant, as we actually know only a small percentage of all Middle Bronze Age burials, the barrow burials. However, when we compare likes with likes - Middle Bronze Age barrows with urnfield barrows - the increase is rather substantial for some urnfields. The bronze items from burials dating to the Late Bronze Age are from a different nature than those from Middle Bronze Age burials. Our database of Late Bronze Age burials contains 15 bronze objects, of which 8 pins and 7 unidentified objects. They come from both centre and offcentre burials. In general, pins are the most recurrent metal artefact types known from urnfields, which are followed by rings and then pendants, gilded rings, spirals, bronze beads, and several razors and tweezers. Pendants, gilded rings, razors and tweezers appear to be restricted to the Early Iron Age burials. However, their predominance in Iron Age burials might be result from the fact that that these are known in larger numbers than Late Bronze Age burials – pendants, tweezers and razors may have occurred in Late Bronze Age burials, albeit in low numbers. Weapon burials do not seem to occur before the end of the Late Bronze Age (Fontijn 2002, 198203). Besides being the most recurrent type of artefact, the bronze pin also shows most variation. In general they are less conspicuous, though, than most Middle Bronze Age B pins. It is unclear whether these are local items or imports: although most pin-types are known from other regions, their rather simple form and techniques suggest a local production. The same is probably true for the bronze rings, which are mostly plain and very simple. These come in different sizes, suggesting different functions such as bracelets, finger rings and perhaps even horse gear (Fontijn 2002, 199). All these bronze objects were found in different states among the cremated human remains; both in pristine, unburned state and in deformed state. This means that the same types of objects sometimes were placed on the deceased before cremation and were collected after burning 69 of the body, while at other times were added to the cremated remains after burning (Fontijn 2002, 203-4). 3.4 Discussion Ever since W. Kersten (1948) dubbed the term Niederrheinische Gräbhugelkultur for the Ha A and B groups living in the Lower Rhine basin, an ongoing discussion has concerned the cultural affinity of these groups to the preceding Middle Bronze Age groups on the one hand and the contemporary Urnfield groups of central Europe on the other (see also Verwers 1971; Desittere 1968). The main question is: are we dealing with a group of the Urnfield culture proper? The answer given to this question by different scholars is not so much based on the nature of the cultural differences and similarities between the Niederrheinische Grabhügelkultur and the Middle Bronze Age or Urnfield groups, but rather on the relative importance ascribed to either instances of continuation of local practices or influences from the central European cultural groups. To my opinion, this discussion is of little interest if we want to understand how and why changes in burial rituals occurred at the end of the Middle Bronze Age. What is of interest is giving a proper description of which practices did change and which did not, and of course when they changed. In the previous paragraphs we have given a description of the Middle Bronze Age and Late Bronze Age burial monuments, burial practices, and pottery and metals from graves. Thus far I have largely refrained from a comparison of the burial traditions of these periods. In this paragraph we will focus on how the burial rite changed at the end of the Middle Bronze Age and the Late Bronze Age. I will also try to establish when these changes took place and in what number new elements occurred through time. 3.4.1 Patterns of Cultural Change I will start this discussion with highlighting how burial monuments have changed throughout the Bronze Age. The first notable change concerns the surrounding features of round mounds. The Middle Bronze Age barrows are characterized by a large variation of surrounding features: ring ditches, 6 six types of post circles, bank and ditches, and stone circles. This variation appears to survive well into Middle Bronze Age B, from which 14C-dated examples of several types of post circles and ring ditches are known. But at the start of the Late Bronze Age this variation seems to have disappeared – ditches have become the dominant type of surrounding feature, both for long and round barrows. The round barrows have also significantly decreased in size, the second change of burial monuments. Middle Bronze Age barrows have a diameter ranging between 5-19 m, with an 70 average of 11,3 m, while Late Bronze Age barrows range between 4-8 m, averaging on only 5,9 m. Middle Bronze Age barrows seem to have maintained their large size up to the end of the period, as all, except one, of the barrows dated to the Middle Bronze Age B have a diameter ranging between 9,2 and 15 m. The third change concerns the shape of the monuments. Whereas, the variation in surrounding features decreased, the shape of monuments diversified, but only slightly. One new barrow type occurred during the Middle Bronze Age B, the long barrow. Initially, these were only of the smaller Riethoven type, sometimes rather irregularly or unusually shaped and often surrounded by single or multiple post settings. In the Late Bronze Age long barrows were solemnly or predominantly surrounded by ditches and varied more in size: both short Riethoven type monuments and long Goirle monuments were constructed, and long barrows that were somewhere in between these types (Hilvarenbeek-Laag Spul; Verwers 1975). Round barrows are still dominant at urnfields, though, but at some urnfields long barrows make up a large part of the burial monuments (for instance, Hilvarenbeek-Laag Spul and Knegsel-Knegselsche Hei). The last change concerns the amount of burial monuments constructed. Bourgeois and Arnoldussen (2006) have noted that the majority of all Middle Bronze Age round barrows were erected before 1400 BC. The amount of barrows erected after 1400 BC is probably very low. However, with the beginning of the Late Bronze Age the amount of barrows constructed rapidly rises again. Every urnfield contains many small barrows. This grouping of barrows does not seem to be a new phenomenon, though. Already during the Middle Bronze Age the location of round mounds seems to have been determined by the presence of older barrows. A clear preference existed in this period to place new mounds near existing ones, and also to re-use older barrows (Bourgeois & Fontijn 2008, 48-9). However, in terms of number of barrows, these groups are of a much smaller scale than the average urnfield. Changes did not only occur in the form of burial monuments, but also in the manner in which people were interred in these monuments. The dominant burial practice of the Late Bronze Age, cremation, was also the main burial practice of the preceding period. However, this appears to be especially the case for secondary burials: more than 12 times as many secondary cremation burials than inhumation burials are known - more than 90%, against less than 60% for the primary burials. These cremated remains were interred in different ways. Of the primary burials a large part of the cremation burials are interred in structures that seem to refer to inhumation burials: burial pits and tree coffins. A third is interred in small pit, either with or without urn. Of the secondary burials almost half of all burials were interred in a small pit and more than a third 71 was buried in an urn. Compared to the primary burials the cremated remains in a burial pit or tree coffin make up a much smaller part of the secondary burials. As said, cremation is the main burial practice of the Late Bronze Age. In most urnfields these were probably interred without a ceramic urn. And all burials of which it is known in what kind of structure the remains were interred appear to be small pits. Apparently, the diversity of burial structures existing during the Middle Bronze Age has largely diminished or perhaps totally disappeared at the beginning of the Late Bronze Age. A trend which has perhaps already started during the Middle Bronze Age B, as only urn and pit burials date after 1350 cal BC. So, two changes of burial practices seem to have occurred at the onset of the Late Bronze Age: the rite of cremation came to fully dominate and the variation in burial structures has diminished to interments in small pits, with or without a ceramic urn. Interestingly, the practices that have come to dominate in the Late Bronze Age are those that already dominated in secondary barrow burials: amongst burials in a barrow the percentage of cremation burials is significantly higher in secondary than in primary burials as is the percentage of interments in a small pit (with a percentage of urn burials that roughly compares with that of urnfield burials – compare table 3.6 with Verwers 1971, fig. 1). Finally, some changes occurred amongst the items deposited in the burials. Let us first look at how the ceramics have changed. In the Middle Bronze Age three types of coarse pottery were in use, Hilversum, Drakenstein and Laren pots. Of these only the simplest pot type, the Laten pot, is found in Middle Bronze Age B burials. Amongst which are some a-typical shapes which might display some early central European influences. At the start of the Late Bronze Age the number of pot types produced has vastly increased, as has the variation in decoration. This new pottery is thinner and often polished. However, not only the type of pottery deposited in burials changed. Also the function of the pots placed along the deceased changed. During the Middle Bronze Age pots were solemnly used as urns; only two examples of pots as grave gifts are known. In the Late Bronze Age this seems to have significantly changed: about half of all vessels were grave gifts, instead of urns. Apparently the role of pottery during the burial rite – at least during the stage of interment – had changed. Besides the ceramics, the metals deposited in burials also changed from the Middle to Late Bronze Age. Only 4,3% of all Middle Bronze Age burials contained metal artefacts, all bronzes. These were all found in primary graves in an unburned state and consisted of (exotic) weaponry, 72 grooming equipment and perhaps ornaments. From secondary burials only green staining on cremated bone is known. All the bronzes date to the Middle Bronze Age A. The only metals known from Middle Bronze Age B burials contexts is weaponry deposited in or near barrows in non-burials. Although metal work in graves was still the exception rather than the rule, the amount of graves containing metal work had considerably increased in the Late Bronze Age. At some urnfields as much as 18% of all burials contained bronze objects. These bronzes consisted of simple, (probably) locally made objects; mainly pins and rings – no weaponry and no, or almost no grooming equipment. These are found in both centre and off-centre burials and in both burned and unburned state. So, three changes seem to have occurred concerning bronzes in graves: firstly, the amount of graves with bronzes has significantly increased; secondly, the kind of items deposited had changed – whereas Middle Bronze Age burials still contained weaponry and grooming equipments, these signs of a martial identity had been replaced by simple ornaments; thirdly, the role of the metals during the burial rite had changed – both pristine bronzes and bronzes collected from the pyre were deposited in the graves during the Late Bronze Age, while from the Middle Bronze Age only unburned items are known. So in total twelve major changes in burial ritual appear to have occurred from the Middle to the Late Bronze Age. I have summarized them in table 3.10. These changes are, in fact, part of two major kinds of changes that seem to have taken place. On the one hand, the burial rite simplified significantly. In the Middle Bronze Age round mounds could have been surrounded by many different structures, people could be interred in different kinds of burial structures and could be cremated or inhumed. However, during the Late Bronze Age the round mounds became smaller, all monuments were surrounded by ditches, all people were interred in pits, and all the deceased were cremated. The only variation existed in the long barrows of different sizes. On the other hand, the kind of items deposited in burial diversified. During Middle Bronze Age B only one kind of ceramic vessel was deposited in graves, all the vessels were used as urns, and metal artefacts were absent. In the Late Bronze Age many kind of vessels were deposited in burials, both as urns and as grave gifts, and many more graves contained bronzes, both in burned and unburned state. All the items were, however, in a local idiom: rather simple, locally produced ceramics and bronze ornaments. 73 Burial Monuments Ceramics 1. Large variation in surrounding feature type diminished to one type: a surrounding ditch 2. Round barrows significantly decreased in size 3. The long barrow appeared and diversified 4. The amount of barrows constructed increased significantly: large groups of small barrows appeared 7. Number of vessel types and decoration motifs increased significantly 8. The quality of the vessels increased 9. Pottery became significantly more often used as a grave gift rather than urn Burial Practices Metals 5. Cremation became the single form of body treatment 6. Large variation in burial structures diminished to one type: a small pit, with or without ceramic urn 10. The amount of graves with bronzes significantly increased 11. Simple ornaments became the dominant kind of bronzes deposited in burials 12. Bronzes became deposited both in burned and unburned state Table 3.10 Overview of changes in burial ritual occurring from the Middle to Late Bronze Age. 3.4.2 Quantifying the Patterns So now we have gained a good overview of the changes occurring from the Middle to Late Bronze Age (table 3.12). In this paragraph we will try to quantify these instances of culture changes: in what timeframe did the changes occur and in what numbers? There are, however, two problems with answering this question. Firstly, typo-chronology of Late Bronze Age pottery – the main means of this study for dating burials – does not allow for phasing within the Late Bronze Age. Changing frequency of different elements within this period can therefore not be established. We will therefore work with the assumption that the characteristics of Late Bronze Age urnfields, as described in the previous paragraphs, were already dominant at the beginning of this period and remained so during this period. This seems to be a reasonable assumption, as the latest examples of typical Middle Bronze Age practices date before 1050 BC (table 3.2). Secondly, all datable pottery types post-date the end of Ha A. However, as we will see below, most elements of the urnfield phenomenon already existed in the earlier parts of Ha A. However, as no examples can be securely dated to the period between 1200-1050 BC we known little of the nature and frequency of the elements during this period. Let us start with the changes of burial monument forms. The first two changes, the decrease of surrounding feature variation and round barrow size, appear to be rather sudden changes. Both 74 barrows with post circles of different types and with a large diameter were probably constructed until the beginning or into Ha A (table 3.2). The earliest radiocarbon dates for ring ditches from urnfields are from Hilvarenbeek- Laag Spul (findnr. 46: 2885 ±35BP or 1208-938 calBC) and Goirle-Hoogeind (Findnr. 29: 2870 ±50BP or 1213-912 calBC), which suggest that it is likely that the first of these ring ditches date to the earlier parts of Ha A (Lanting & Van der Plicht 2003, 222-3). So, somewhere during Ha A the small round barrows with ring ditch came to dominate the burial grounds. It is also likely that somewhere during this period the first real urnfields – barrow groups consisting of a rather large amount of such small round mounds – appeared. Again this must have been a rather sudden change, as the period after 1400 BC is characterized by a very low amount of newly constructed round mounds. The long barrow has developed along somewhat different lines. Contrary to the round mound, the long mound was a rather recent development. The first two occurrences of this type of barrow, at Haps-Kamps Veld, date between 1500 and 1300 calBC. Two slightly later occurrences, from Veldhoven-Heibloem and Beerse-Mezenstraat, date to the second half of Middle Bronze Age B (table 3.2; Delaruelle et al. 2008). These are all long beds of the Riethoven type and are surrounded by post settings and/or ditches. At the start of the Late Bronze Age the long barrows have diversified: the short Riethoven types still occur, but a second type, the long Goirle type, is now also constructed. Like the round mounds, these were now all surrounded by ditches. The earliest radiocarbon dates of Goirle type monuments fall somewhere in the twelfth to tenth century calBC (Lanting & Van der Plicht 2003, 222). It is therefore not unlikely that the diversification of long barrow types has occurred somewhere during Ha A. During this period the amount of long beds at burial grounds must also have increased, as they sometimes make up a large part of the Late Bronze Age urnfields. The frequency of long beds during the Middle Bronze Age is hard to establish as only a few examples are known from this period, but this alone suggests that the amount of long beds at Middle Bronze Age cemeteries was significantly lower than at urnfields. Quantifying the changes in burials practices is harder than for the changes of burial monuments. Firstly, cremation became the single burial practice. We now that during the Middle Bronze Age cremation was already the dominant rite, especially for secondary burials. However, the percentages given in the previous paragraphs are for the entire Middle Bronze Age. It might therefore very well be that at the end of this period cremation was already the single form of interment. But it is also possible that the amount of inhumation burials has increased during the Middle Bronze Age B, like in the Northern Netherlands (Lohof 1994). 75 Secondly, the variation in burials structures had diminished significantly at the beginning of the Late Bronze Age: interments in a pit are virtually the only burial structures found at Late Bronze Age urnfields. However, it is hard to say when this type of structure came to dominate. Burials with other types of structures were all 14C date before 1400/1350 calBC. Those that might date after 1350 calBC are all pits. This might indicate that the loss of variation of burial structures might have occurred already around 1350. However, the amount of dated burials is small (N=10) and come from just three sites. In the case of such an unrepresentative sample the absence of evidence is certainly not the evidence of absence. Concerning the ceramics and metals deposited in burials we noted six changes. These are probably all sudden changes, occurring somewhere during Ha A. Firstly, there are the changes in the type of pottery found in burials: the types of pottery diversified and their quality improved. No logical predecessors to this urnfield pottery are known from the Middle Bronze Age B. In fact, the urns found in burials from this period are all of the simplest, crudest type, the Laren type vessel. A few of these vessels are rather a-typical with a tripartite profile and sharp angles, but still these do not resemble the urnfield pottery; only the coarse Late Bronze Age Grobkeramik. The earliest central European influences on Late Bronze Age pottery date to the end of Ha A or the beginning of Ha B, but bronzes date the earliest urnfield pottery already to the earlier parts of Ha A (see paragraph 3.3.3). The latest examples of Laren pottery possibly also date to Ha A (see table 3.10). So during Ha A a transition occurred from Laren to urnfield pottery. Also, during Ha A pottery started being used as burial gift instead of only urns, the amount of graves with bronzes increased, simple ornaments became the dominant kind of metal artefact placed in graves, bronzes became deposited also burned state instead of only in unburned state. For none of these phenomena Middle Bronze Age B examples are known, so it is likely that they started somewhere near the beginning of the Late Bronze Age. 3.5 Conclusion In this chapter I have tried to answer the first set of research questions of this study: how and when did the burial monuments, burial practices, ceramics and metals that were characteristic for the urnfield burials introduced in the southern Netherlands? To answer this question a comprehensive description was given of the burial rites of the Late Bronze Age and the preceding Middle Bronze Age. For the Middle Bronze Age use was made of Theunissen’s (1999) overview, while for the Late Bronze Age the characteristics were discussed of those burials that could be dated securely in the Late Bronze Age and of the urnfields in general that contained evidence of 76 Late Bronze Age activities. This overview of burial rites made it possible to highlight twelve major changes. One the one hand, the burial rite seems to have significantly simplified: into existence came large group of small barrows, which were all surrounded by ditches, had one type of burial structure, a small pit, and which only contained cremations, no inhumations. Only, the long barrow was a new element, which displayed some variation in size. On the other hand, the kind of items deposited in burials had diversified: more types of pottery, no longer only used as urn, and significantly more graves with bronzes, all simple ornaments, both in burned and unburned state. It appears that almost all changes were rather sudden ones. Most characteristics or elements of the Late Bronze Age burial rite either appeared for the first time during Ha A or suddenly came to dominate during this period. Only the rite of cremation and the small pit as burial structure may have dominated already a little earlier than Ha A. 77 78 4. Ideas and Beliefs: Urnfields and Identities 4.1 Introduction In the previous chapter I described the patterns of change in burial rite practices. This was mainly an overview of changing behaviour - the 'phenotype' in terms of genetic evolution. As I have adopted an ideational concept of culture (see chapter 2) for this study, I am also interested in the ideas and values behind the practices - the cultural equivalent of the 'genotype'. It are these ideas and beliefs that are passed on from individual to individual, not just the behaviour. Interpretive archaeology has developed an extensive array of theories and methods to study the behaviour and, especially, the cognition of the people behind the pots. In this chapter I will employ some of these methods and theories to gain more insight into those subjects that figure most promptly in the studies of the meaning of urnfields: the personhood of the buried and group identity as expressed in the layout of the cemeteries. For the analysis the same dataset will be used as in chapter 3. 4.2 The Meaning of Urnfields Studies of the beliefs and values expressed at funerals and burial grounds often focus on identity. This can be a personal identity - the personhood of the diseased in life or death - or a communal identity - the burial ground as a symbol of a collective. Extensive research on the meaning and symbolism of Dutch urnfields is unfortunately rather rare. Little is known about the kind of persons buried at urnfields (Roymans & Kortlang 1999, 34) and notions on urnfields as symbols of local communities are mainly based on the fixed nature of the burial grounds and not on a proper understanding of the manner in which identities were expressed at these sites (Gerritsen 2001). In this paragraph I will try to gain some further understanding of the meaning of urnfields. 4.2.1 Personal Identity: Metals and Ceramics During life and in death an individual is defined as a person, a social category. From ethnography we know that material culture often plays an important role in the construction of a person (Hoskins 1998). Objects with specific meaning do not only signal specific identities, but are actively engaged in the constitution of a person as constituent parts that are exchanged through the life of an individual. As roles and statuses are thus marked and constructed by material culture, they can be archaeologically discerned as long as we know the meaning of the objects associated. This meaning is often not intrinsic to the object, but comes about through a life-path 79 (cf. Fontijn 2002, 25-8). But how do objects become meaningful? And how can we as archaeologists reconstruct these meanings? To gain an answer on the first question the concept of cultural biography as defined by Kopytoff (1986) is useful (cf. Fontijn 2002, 26). Cultural biography is an anthropological concept that was used by Kopytoff to describe the life history of things that go through shifts in their social and economic meaning in the processes of exchange and circulation. Cultural biography refers to a ‘theoretical aware biographical model […] based on a reasonable number of actual life histories’ (Kopytoff 1986, 66). Important is the notion that societies offer different biographical possibilities to different categories of objects and that desirable models of a biography of an object – idealized biographies – exist in societies, of which real-life may departure. What makes a biography cultural is that an object is looked at ‘as a culturally constructed entity, endowed with culturally specific meanings, and classified and reclassified into culturally constituted categories’ (Kopytoff 1986, 68). For archaeological purposes, a significant difference can be made between specific biographies, and generalized biographies (Grosden & Marshall 1999, 170-2). ‘Specific biographies are about the idiosyncratic histories of objects [whereas] the characteristics of generalized biographies […] go back to a widely-shared expectation as to their kind of lifepath’ (Fontijn 2002, 26). The latter can be discerned as patterns in the archaeological record. The former are archaeologically harder to discern, since they are outside established patterns. They may be recognized sometimes, though, as strange phenomena (Fontijn 2002, 26). So, the meaning of objects with a generalized biography can be reconstructed from a patterned use-life of object of a certain object category. If we assume that the items associated with the deceased in burials signal the personhood of the dead, we can reconstruct this identity by determining the meaning of the items. So a reconstruction of the general life-path of the items is needed first. In the previous chapter we saw that in barrow and urnfield burials there are mainly two kinds of objects: metals and ceramics. The life cycle and meaning of the former category has already been studied by Fontijn (2002, chapter 9) and the results of this study will be summarized in this chapter. For metals Fontijn (2002, 27-35) has summarized the most important archaeologically visible variables for each phase of the life-cycle of an object. I have slightly modified this overview so it can be used to study the biography of ceramics (table 4.1) in the remainder of this paragraph. I will start the analyses of personhood with a short summary of Fontijn's study of the metals from Late Bronze Age and Iron Age urnfields. In chapter 3.3.4 the main characteristics of these metals were already discussed. We saw that in general, pins are the most recurrent metal artefact types 80 known from urnfields, followed by rings and then, spirals, bronze beads. Pendants, gilded rings, razors and tweezers appear to be restricted to the Early Iron Age burials, but may have occurred in Late Bronze Age burials in low numbers. No weapon burials date before the end of the Late Bronze Age (Fontijn 2002, 198-203). Bronze pins are the most recurrent type of artefact and also most variable. Although most pin-types are known from other regions, their rather simple form and techniques suggest a local production. The same is probably true for the plain and simple bronze rings. These come in different sizes, suggesting they had different functions such as bracelets, finger rings and perhaps even horse gear (Fontijn 2002, 199). All these bronze objects were found in different states among the cremated human remains; both in pristine, unburned state and in deformed state. Apparently the same types of objects were sometimes placed on the deceased before cremation and were collected after burning of the body, while at other times they were added to the cremated remains after burning (Fontijn 2002, 203-4). Table 4. 1 Decisive steps in the life-path of ceramics: archaeological correlates. (After Fontijn 2002, table 3.2) 81 Metal ornaments, pins and toilet articles have an apparent role in the construction of identity as they dress people to look like certain persons. Fontijn (2002, chapter 9) explains that, although the precise meaning of such appearances escape us, they served sometimes to make differentiations between certain kinds of female identities. In general, the beliefs concerning the personhood of the interred appear to have been ideosyncratic, since there are differences in associations between kinds of objects and individuals of different age and sex from place to place. Conventions on specific female identities only existed at the level of the micro-region (for instance, conical pendants as a typical dress for the Kempen in the Iron Age). These identities in local idiom contrast markedly with the supra-regional identities expressed by high quality, nonlocal items deposited at natural places in this period. Local and supra-regional identities were apparently kept physically and conceptually apart (in chapter 5 this system of selective deposition will be further discussed). Let us now see if ceramics have a similar, local meaning as metals. But before doing this, it has to be noted that at Late Bronze Age urnfields there are many burials with no grave goods, at least no goods that were preserved up till this day. In chapter 3 I explained that the number of non-urn burials at Late Bronze Age urnfields is 44% or higher. In some of these burials the cremated remains were found packed together suggesting that they were originally deposited in an organic container or cloth. Well-preserved remains of such a container or cloth have never been found. Only at Mook-Nieuwbouw Bovensteweg 20 a humus rich layer was found at the bottom of burial 1, which are probably the decayed remains of an organic container (Bouma 2009). Therefore we can say nothing about the nature and meaning of these items. Culture 1050-800 BC Material Ceramics Undetermined Bronze 1500-800 BC Stone Ceramics Organic Object type Pot Undetermined Undetermined Pin Undetermined Undetermined Pot Undetermined 1 28 2 - 2 78 1 1 3 1 1 3 - 3 22 3 6 5 1 Total 130 1 1 8 7 1 8 1 Table 4. 2 Number of Late Bronze Age items per material category. The numbers 1 to 3 indicate the reliability of dating (see paragraph 3.2.2). 82 This leaves us with just the ceramics to discuss. In total 131 ceramic items were inventoried that could be dated to the period 1050-800 BC and another 8 that could be dated to the period 1500-800 BC (of which most probably date to Ha A or later) (table 4.2). As this thesis is a study of literature and not of materials, the pots have not been personally examined by the author. We therefore have to do with the information given in the original excavation reports of the sites where the pottery was found. This information is often scanty, with the result that many steps in the life-path of the pots cannot be reconstructed (table 4.1). Namely information on the raw material, production technique, use-life, and arrangement of objects is mostly lacking. The other steps can be reconstructed to a further or lesser extent. Concerning the production of the pots a first important aspect is the intended function of the pots. Were all pots produced with a function as urn in mind? It is difficult to answer this question. This question could be negatively answered if most pots showed signs of an extensive use-life, but as said information on the use-life is almost fully lacking. Only a single example of a mended pot could be dated to the Late Bronze Age. Findnumber 2 from Hilvarenbeek-Laag Spul is an amphora with a Late Bronze Age cylindrical neck and sharp biconical profile as ground shape (Verwers 1975). This pot has two repair holes beneath the rim at both sites of a crack. Such damage and repair is, however, no solid indication of everyday use. The pot could also have been produced to function as urn, cracked, and got repaired to prevent further cracking before use as Site type Barrow, unspecified Barrow, centre Barrow, offcentre Barrow, centre-edge Barrow, edge Barrow, surrounding feature Flat grave Possible flat grave Possible grave Unspecified grave Total Skill Undefined - Poor Total Average - 2 Excellent 2 12 3 4 1 16 12 1 32 17 - - 1 - 1 2 2 6 - 10 - - 1 - 1 1 1 3 - 12 8 - 16 9 1 - 2 - 1 5 2 4 7 20 12 64 5 101 4 Table 4. 3 Number of vessels of certain quality per grave type for the Late Bronze Age (1050-800 BC). 83 urn. To say anything about the extent and nature of the pottery, use-wear analysis is needed first. There is, however, an important indication that at least some pots were not intended for everyday use. If we compare the Late Bronze Age pottery from settlements (Van den Broeke 1991; Arnoldussen & Ball 2007) with that from urnfields (Desittere 1968) we find at each type of site pots with both crude and refined shapes and decoration. However, at urnfields one finds pots of certain quality and type and with certain kinds of decoration that are not found at settlements. Pottery types that are not found at settlements are shoulder beakers, high shouldered conical necked urns, low-shouldered urns with funnel neck, classical urn-like beakers, and bowls of type Vogt XII - all classical urnfield ware (Desittere 1968, 58). The absence of these pot types at settlements can be explained, however, as the result of the small amount of examples of this type known combined with the low amount of Late Bronze Age settlements known. Also, the occurrence of these types seem to be mainly restricted to the micro-region of the Kempen (Desittere 1968, kaart 7), from which no settlements are known. Next to that, these vessel types tend to be dated early (Desittere 1968) while the known settlement complexes are slightly younger (Arnoldussen & Ball 2007). More significant, therefore, is the absence of Kerbschnitt decoration at urnfields; the defining trait of the northwestern group of the urnfield culture. As this type of decoration is more abundant (Desittere 1968) and more wide-spread (Desittere 1968, kaart 8) at urnfields, there absence at settlements is significant. It means that there is at least one kind of pottery that, although perhaps not produced for inclusion in burials, was at least not intended for use in daily life. Apparently, Kerbschnitt decoration had a specific meaning that prevented it from being used in daily life. Unfortunately it will probably remain unknown what this meaning is. What these examples also show is that amongst the pottery from urnfields there exists quite some variation in style, concept and production technique: some pots display signs of excellent craftsmanship while other are poorly made, some pots are of a common type while others are rather unique, and some pots display a regional style while others are of a locally derived type. Unfortunately, as there are only a few Late Bronze Age burials of which the human remains have been analyzed it is impossible to relate these differences to sex and age of the deceased (table 3.9). Also there is no significant patterning in the types of pots found in different graves and positions of urnfield barrows (table 4.3 & 4.4). I do want to discuss the differences in style some further, though, as it can slightly nuance the picture sketched by the metals. 84 Site type Barrow, centre Barrow, off-centre Barrow, centre-edge Barrow, edge Barrow, surrounding feature Barrow, unspecified Flat grave Possible flat grave Possible grave Unspecified grave Vessel type Amphora Bowl Grobkeramik Henkeltöpfe Doppelkoni Beaker Dekkeldose Undetermined Conical necked urn, classical Funnel necked urn, non-classical Urn, undetermined Bowl Grobkeramik Henkeltöpfe Dekkeldose Undetermined Conical necked urn, classical Conical necked urn, non-classical Funnel necked urn, classical Urn, undetermined Amphora 1 1 1 1 1 1 1 1 1 1 - 2 1 4 1 2 1 3 2 7 1 2 1 1 2 1 2 1 1 3 1 1 1 1 3 1 - Total 1 5 1 2 1 5 2 8 2 2 3 3 1 3 2 1 2 2 2 1 1 Amphora Henkeltöpfe Beaker Undetermined Funnel necked urn, classical Henkeltöpfe 1 2 2 1 2 1 - 1 1 - 2 3 1 2 2 1 Bowl Conical necked urn, non-classical Conical necked urn, classical Bowl Grobkeramik Henkeltöpfe Beaker Undetermined Conical necked urn, classical Conical necked urn, non-classical Funnel necked urn, classical Urn, undetermined Urn, tall Amphora Henkeltöpfe Undetermined Conical necked urn, classical Conical necked urn, non-classical Funnel necked urn, non-classical Urn, undetermined Bowl Dekkeldose Conical necked urn, classical Funnel necked urn, non-classical Bowl Henkeltöpfe Undetermined Funnel necked urn, non-classical 2 1 1 1 1 1 1 1 1 1 1 1 - 2 1 1 1 2 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 3 2 1 2 1 1 1 1 1 2 1 1 2 1 1 2 1 2 1 1 2 1 2 Table 4. 4 Urn types per grave type for the period 1050-800 BC. The numbers 1 to 3 indicate the reliability of dating (see paragraph 3.2.2). 85 As explained above, the metals found in urnfield burials are all of a simple, local style, apparently stressing a local identity. Similarly, most vessels found in burials are local types. But as we saw, some pots clearly display a supra-local style: the classical urnfield style of central Europe. Through the vessels made in this style some persons were associated with a supraregional community. That this association must have been deliberate and recognized is suggested by the fact that the classical pottery types are rare at urnfields - they must have stood out against the local vessel types that had probably already developed by the beginning of Ha B (see chapter 3). In fact, some vessels posses such an unusual type of decoration and are of such a high quality that it is even possible that they were imported (Desittere 1964; Desittere 1968, 42). However, examples of vessels in a clear supra-regional style are rare and, as said above, restricted to the Kempen (Desittere 1968, kaart 8). Throughout the southern Netherlands most people were interred in or with vessels of a local style. And although there are differences in the quality and types of these vessels, they do not appear to signal major distinctions in social role or status differences were expressed in a local, egalitarian idiom. In closing I will take a quick look at the manner of deposition and the position of the ceramics. In most excavation reports little information is given on the position of ceramics, other than used as urn or not. When we make an overview of the position of different kinds of vessels no significant patterns emerge, other than Henkeltöpfe that are conspicuously often deposited in surrounding ditches (table 4.5). One can imagine how such handled cups are used for drinking and poring liquids in rituals carried about the burial monuments. In the graves the smaller vessels, such as bowls, beakers and Dekkeldosen, tend to be used more often as accessory vessels, while urns are mainly used as containers. The smaller vessels probably had a function as holders of foods, liquids, etc. deposited along the deceased. Many of the vessels from burials were found broken (n = 51). It is, however, hard to say whether these vessels were broken at deposition or post-depositionally. The high amount of broken vessels in surrounding features (23 out of 25 vessels) does appear to reflect reality, though. Not only the position of vessel types in the grave, but also in the burial ground at large can be informative on the kind of persons buried at urnfields. Which kind of items and therefore which kind of persons were associated with which kind of burial monuments? This is a question I will answer in the next paragraph. 86 Vessel type Bowl Beaker Dekkeldose Henkeltöpfe Grobkeramik Amphora Doppelkoni Conical necked urn Funnel necked urn Urn, undet.

According to him urnfields were vital for the construction of the identity of local communities during the Late Bronze Age. He explains that at urnfields a communal sense is expressed through a uniform burial ritual and that these collective identities are expressed more often than before as each individual now received its own barrow burial. Gerritsen's notions are based on limited knowledge and understanding of, for instance, the meaning of different monument shapes and patterns in lay-out and development of urnfields. In this paragraph I will try to gain some further insight into these issues for Late Bronze Age urnfields. I will begin where we left of in the last paragraph by examining the relation between different monument types and identities. As said earlier, data on age and sex of the deceased is extremely scarce for Late Bronze Age burials and we therefore have to do only with grave goods to reconstruct identities. Although urnfields are usually characterized as burial grounds with monuments of many different shapes and sizes, this is mainly true for Iron Age urnfields. As we saw in the last chapter, Late Bronze Age urnfields only contain two types of monuments: round barrows and long barrows surrounded by closed ring ditches, each of different sizes. Our main focus should therefore be on differences in meaning of these two types of monuments. Roymans and Kortlang (1999, 42-53) have suggested that long barrows are the burial places of family heads and as such have a more collective significance than other graves. The reasons to suggest this are that: 1. long barrows are always a small proportion of the total number of graves; 2. some long barrows are of extreme size and therefore probably founders burials; 3. ditches of long barrows often contain large amounts of pottery; 4. long beds contain more often than round barrows 2 or 3 graves and these graves often contain more than one individual; 5. in an urnfield there can be multiple clusters of long barrows, suggesting that in a local community several person were qualified for burial in a long barrow; 6. mainly adult males were buried in long barrows. Most of these arguments are based on the analysis of the Early Iron Age urnfields of eastern Noord-Brabant (Theuws & Roymans 1999). Their validity for the Late Bronze Age can therefore be doubted. For instance, the first argument appears untenable as long barrows make up almost half of all graves of the Late Bronze Age urnfield of Hilvarenbeek-Laag Spul (Verwers 1975). Secondly, the supposed founders grave that are substantially longer than other barrows at the same urnfield are not known from any of the urnfields with signs of Late Bronze Age activities (table 3.3). Next to that, there are also many examples of round barrows with more than one burial and sometimes even as much as 5 burials (Van den Hurk 1980, grave 82-86). Also, I 88 Skill Unknown Undet.

The validity of the sixth argument cannot be checked for the Late Bronze Age as no cremated remains from long barrows from this period have been analysed. All in all, it appears that the idea of long barrows as the burial grounds of family heads finds no support in the urnfields of the Late Bronze Age, although this of course does not mean that it is invalid. Unfortunately, the pottery types from the two kinds of barrows give little information on differences between the persons buried in each monument type. No vessel types appear to be predominantly deposited in one of the barrow types (table 4.7), but vessels of poor quality seem to occur slightly more often in long barrow burials (table 4.6). All metal artefacts that could be dated to the Late Bronze Age (N = 15) come from round barrows and flat graves, not from long barrows. So, the only pattern is that burials from long barrows are less rich than round barrow burials. This is, however, a very tentative pattern and a more fair characterization would probably be that burials from round and long barrows contain more or less the same types of artefacts, save perhaps the metal artefacts. This uniformity is reflected in the lay-out of urnfields. The long barrows might have visually contrasted with the round barrows, but otherwise the monuments within an urnfield are rather similar. Between Late Bronze Age urnfields monuments might differ significantly in size, especially the long barrows, but within an urnfield most long barrows and round barrows are of similar dimension, except for one or two barrows that are significantly larger or smaller than others. Even between clusters of long and/or round barrows there are no apparent differences in the dimensions of monuments. Also, the orientation of the long barrows is usually uniform, either parallel with or perpendicular to the orientation of the sand ridges on which urnfields are usually located (Desittere 1968, 50-7). Next to that, there is no apparent segmentation visible at the urnfields with signs of Late Bronze Age activity - there are no clearly separated groups of barrows representing, for instance, different factions within a social collective. Such clustering is known from Iron Age urnfields, where groups of barrows are sometimes separated by empty 89 Vessel type 3 Grave type Round Long barrow barrow - - 1 4 1 1 - - 2 5 1 2 3 11 3 - - 3 6 2 - 3 1 6 4 1 3 1 9 1 4 2 - 1 2 - 1 5 2 2 1 1 1 1 7 4 9 4 2 5 1 3 4 38 3 2 1 3 15 11 4 1 14 49 7 2 Unknown Amphora, Cylinder neck Amphora, Funnel neck Cylinder urn, Classical Cylinder urn, Non-classical Funnel neck urn. classical Funnel neck urn. nonclassical Urn, tall Biconical urn Urn, indet.

At Late Bronze Age urnfields the monuments form a continues conglomerate. Unfortunately, the chronological resolution is to coarse to establish patterns of growth of the urnfields. It could therefore be that at early stages a segmentation was visible, but this was probably soon obliterated as not a single urnfield shows any sign of it. 4.3 Conclusion In this chapter we set out to get insight into the ideas and beliefs behind the burial practices of urnfields. The focus was on the kind of personal and communal identities expressed at the burial grounds. Going from the notions that objects with specific meanings are actively engaged in the constitution of personal identity and that items obtain their meaning through a life-cycle, the biography of the items deposited in urnfields were examined. Fontijn (2002) has already noted that the simple metals from urnfields display a local identity. The same seems to be true for the 90 ceramic vessels found in graves. The pottery displays differences in quality and type suggesting that they had specific meanings. Some people were even interred in or with vessels in a distinct supra-regional style. Such vessels are, however, extremely rare and limited in geographic extent. In general people were interred in or with vessels of a local style, signalling no apparent major distinctions in social role or status - differences are expressed in a local, egalitarian idiom. This is in line with the manner in which communal identities are expressed through the lay-out and monument forms of urnfields. Two types of barrows were constructed at the burial grounds: long barrows and round barrows of different sizes. The objects deposited in the two kind of monuments appear to be rather similar, given no indication for major differences in the kinds of person being buried in them. A similar uniformity is expressed in the lay-out of the urnfields: within an urnfield most monuments are of similar dimensions, have a similar orientation and are part of a continuous conglomerate. So, like the personal identities, the external appearance of urnfields appears to be characterized by similarity and equality. The collective rather than the individual seems to be stressed at urnfields. 91 92 5. Social and Cultural Context 5.1 Introduction In the last two chapters I have described how the burial ritual had changed from the Middle to the Late Bronze Age. In chapter 3 I started with a description of the material characteristics and traditions current in these periods and the frequency in which these occur. In chapter 4 we took a look at the ideas behind this behaviour. Thus we have established the patterns of change in the nature and frequency of the cultural variants that are part of the urnfield phenomenon. In order to understand how these patterns came about, we need to gain a proper understanding of the social and cultural context in which the cultural variation had spread. Recently this context has been thoroughly studied by several scholars. However, the results of these studies have not yet been incorporated in a model of the genesis of urnfields. In this chapter I will do this by answering the last set of research questions of this study: what developments occurred in Middle and Late Bronze Age social structure and ideology, material conditions, demography and population structure, communication channels and power relations? Through answering these questions the building blocks for a Darwinian model of cultural change will be formed: the life history of the carriers of cultural variants, the relevant transmission processes, the cultural, social and material constraints, and the population structure. 5.2 Data & Methodology As said, the Middle and Late Bronze Age socio-cultural context has been extensively studied by several scholars. Only, the results of these have not yet been brought together to provide a comprehensive picture of the Middle and Late Bronze Age societies. This is what I will do in this chapter. No new evidence will therefore be presented here; rather the original part will be the assembling of different, already existing strands of information in a new framework. 5.3 Cultural Constraints: The Value System In chapter 2 we discussed the premises of coevolutionary theory of culture change. Several hypothesis of this theory were formulated by William H. Durham, the first and most important being that: the selection of ideas and beliefs on the basis of the cultural values individuals hold is the main force of culture change (1991, 204). Foreign ideas and beliefs might be misunderstood, disliked and neglected because of a mismatch of values between cultures or subcultures. In this way options may be blocked by cultural constraints, such as preconceptions, prejudices, and 93 technological capabilities (Durham 1991, fig. 4.5). In this paragraph we will therefore try to gain a thorough understanding of the value systems of Middle and Late Bronze Age societies in the Meuse-Demer-Scheldt area. The main sources for such knowledge are settlements, burial grounds and ritual deposits. These three site types have all a long research history and have recently been thoroughly studied by several scholars (Fontijn 2002; Gerritsen 2001; Arnoldussen 2008). An overview of the insights gained in these studies on Bronze Age value systems will be given here. Fig. 5. 1 Reconstruction drawing of Middle Bronze Age farmhouse. (Schinkel 1998, fig. 22) 94 5.3.1 Settlements The first site type to be discussed is the Bronze Age settlement. From the southern Netherlands 32 Bronze Age house plans are known, of which 26 date to the Middle Bronze Age (Arnoldussen 2008, 202-204). The Middle Bronze Age B, that is, as no Dutch house plan can be securely dated before the 15th century BC (Bourgeois & Arnoldussen 2006). The farm houses of the southern Netherlands have a three-aisled appearance, with each rafter being supported at its base and at about one third of the length by upright posts (fig. 5.1). The wall was probably located outside the outer posts and the entrances were situated opposite each other on the long sides. The houses are between 14 and 32 m in length, with an average of c. 20,5 m. The width between the outer posts ranges from 7,5 tot 4,5 m, with a mean of 6,6 m (Arnoldussen 2008, 202-4; Gerritsen 2001, 4951). What appears to be characteristic for these longhouses is not their length nor the possible indoor byre-section that is unconvincingly inferred by several scholars (Arnoldussen & Fokkens 2008, 31). In fact, it is the apparent regularity with which the roof-bearing posts were placed. A survey of 179 Bronze Age houses from the Netherlands has shown that these posts were placed at a standardised distance of 2,0-2,3 m throughout the entire house (Arnoldussen & Fontijn 2006, 295-6). This standardisation cannot be related to possible stall-boxes as it is maintained in the supposed non-byre section. Neither can structural considerations be the reason, as both large and small houses display this regularity. Apparently it was regularity itself that mattered. The care and attention paid to the structures indicate that the average Middle Bronze Age dwelling – and with it probably the household and domestic activities in general – had come to possess a social and ideological significance that in previous periods appear to have been reserved for special, ‘ceremonial’ buildings (cf. Arnoldussen & Fontijn 2006, 295-6). The ideas behind the observed regularity elude us, however. Perhaps it is simply the result of an applied measurement system based on bodily portion or it might have to do with the embedment of the house in a proper cosmological scheme (Arnoldussen 2008, 219-22). What is clear, though, is that the regularity and elaboration of Middle Bronze Age houses is part of a tradition that is shared at a supraregional level and across many generations. According to Arnoldussen and Fontijn, this suggests a “sense of traditionality, an idea of cyclicity and of repeating ancestral acts” (2006, 307). Something which is reflected in the attitude towards the Bronze Age landscape in general, as indicated by the clustering and frequent re-use of barrows and a structured system of metal deposition in natural places (Arnoldussen & Fontijn 2006). In many areas of the Netherlands the Middle Bronze Age longhouses continue to be built in the Late Bronze Age. However, for the southern Netherlands no longhouses can be dated to the 95 Late Bronze Age. Only six houses can tentatively be dated to the Late Bronze Age and they appear to belong to the second century and a half of this period (Arnoldussen 2008, 223; Arnoldussen & Fokkens 2008, 33). This is a diverse group of rather short houses. The regular spacing of roof-bearing posts as found in the Middle Bronze is no longer adhered to so rigidly and some houses do not even appear to be three-aisled (Arnoldussen 2008, 222-9). The sizes of these houses are more in line with the later Early Iron Age houses, which again show standardized three- or four aisled ground plans. The diminishing size of houses has been correlated with the appearance of urnfields by Fokkens (1997) as being part of the same socio-ideological change, namely a process of individualization that resulted from the opening up of bronze exchange networks. According to Fokkens, the decreasing farmhouse size is a reflection of the splitting of extended families into nuclear families. However, determining the household size from the surface area of ground plans, as done by Fokkens, may be a tricky enterprise (cf. Arnoldussen 2008, 85-8). Especially for Middle Bronze Age houses, for which it is not certain whether a part of the house was used as a byre section (Arnoldussen & Fokkens 2008, 31). Nonetheless, even if only a weak correlation between surface area and number of occupants exist and if only part of Middle Bronze Age houses was used as living area, I think it is still fair to assume a decrease in household size from the Middle Bronze Age to the Early Iron Age, as the average size of the supposed non-byre sections of Dutch Middle Bronze Age houses is 60 m², while the total surface area of Iron Age houses is 20 m² (Fokkens 2003, 14). However, the situation is not so clear cut when we compare Middle Bronze Age houses with Late Bronze Age houses, as the surface area of Late Bronze Age houses often only slightly differs from that of the supposed non-byre section of Middle Bronze Age houses (Arnoldussen 2008, 227). So whether the diminishing house size reflects a change in household size depends on whether or not the Middle Bronze Age house contained a byre section. Also, all the smaller house plans date to second half of the Late Bronze Age. So, if diminishing house lengths indeed indicate a process of individualization it is a change that might have come about only at the very end of the Bronze Age. Of course, the Bronze Age houses were part of a settlement. However, settlement is not a straightforward term to use when describing Bronze Age communities from the southern Netherlands. Generally, when one speaks of settlements, a conglomeration of farmsteads and farmyards comes to mind. Yet, during the Bronze Age in the Netherlands and surrounding regions, settlements consisted of one or two isolated houses that lied dispersed within a certain area. The farmsteads appear to have been single-phased and were relocated regularly over some distance (see Arnoldussen 2008 and Fokkens & Arnoldussen 2008 for an overview of Bronze 96 Age settlement-system models). However, there are certain knowledge gaps when it comes to the Bronze Age settlements, namely the length of time between instances of house relocation, the distances over which houses were relocated, the number of houses that constituted a settlements (and therefore the size of a settlement), and, most importantly, the cause for the frequent house relocation. Wood durability (structural instability), soil depletion of accompanying fields, and household lifecycle are put forward as possible causes, but none are convincing (Arnoldussen 2008, 85-96). What is clear, though, is that a communal sense found no clear physical expression in the settlement during this period. Rather, the community must have been a symbolic construction and the interaction with the natural and man-made landscape must have been vital in the definition of a community (Gerritsen 2001, 109-17). This brings us to the second site type, the burial grounds. 5.3.2 Burial Grounds According to Fokke Gerritsen cemeteries were vital for the construction of the identity of local communities during the Late Bronze Age (Gerritsen 2001, 251-8). He explains that during the preceding Middle Bronze Age practices of social reproduction were grounded in unstable patterns of land use. Population density was low and farmsteads were periodically relocated. Also, burial locations were instable – barrows were either relocated with the farmsteads or farmsteads were located near existing barrows. All in all, this suggests a fluid and dynamic territorial organisation of the Middle Bronze Age landscape, in which “social identity (…) was based as much on differentiated relationships with the ancestors represented by the barrow landscape, as on the more dynamic social relationships that came about through patterns of residence” (Gerritsen 2001, 254). Through time, however, the number and density of barrows increased, and thus a mythical geography was created in which the funerary monuments served as markers of the history of habitation and ancestral presence. Consequently, dwelling would have increasingly involved interacting with the historical and mythical dimensions of the land. Through time this would have led to a closer association of social groups with particular parts of the landscape. Together with rising population levels this would have led to a more restricted residential mobility. Local communities would thus become more fixed in space and the establishment of stable local communities and fixed burial places at the beginning of the Late Bronze Age can be seen as a logical effect of this. At urnfields the communal sense is expressed through the uniform burial ritual and these collective identities are expressed more often than before as each individual now received its own barrow burial. 97 There are, however, several problems with this model. Let us start with the supposed increase in population level. This is mainly based on an argument made by Roymans and Kortlang (1999, 37-8; Gerritsen 2001, 233-4). They argue that a difference in the number of known Middle Bronze Age versus Late Bronze Age burial places reflects a rise in population, as they inventoried 55 barrow groups against 85 urnfields. A first problem with this interpretation, concerns the manner in which barrow groups are defined. This may significantly change the number of groups. Theunissen (1999, 47), who maintains a different definition, discerns 77 barrow groups – just 8 less than the number of urnfields. A second problem concerns differential survival of the two site types. On the one hand, the rather large Middle Bronze Age monuments are more easily recognized than urnfields and therefore possibly less often destroyed, but on the other hand urnfields are much easier to recognize during excavations because of the large numbers of surrounding features and the many urns. It is therefore hard to say how representative the known number of each of these site types is. Thirdly, the known barrow groups are not evenly distributed over the southern Netherlands: apparent clusters exist in the Kempen and in the border-area south of Tilburg, while other areas are conspicuously empty (Theunissen 1999, 52). This patterning is possibly the result of post-depositional processes (Theunissen 1999, 52), which means that we should not compare the overall number of barrows with that of urnfields from the entire southern Netherlands. Rather only the numbers of those regions in which a substantial number of barrows is known should be compared. Also, we must take into account the fact that most barrows were constructed in a 500-year period between 1900 and 1400 BC (Bourgeois & Arnoldussen 2006), instead of an 800-year period as assumed by Roymans and Kortlang. And the first urnfields probably already originated at the beginning of Ha A (see chapter 3), so urnfields were built during a 400-year period, rather than over 250 years. And as most barrows were built during the Middle Bronze Age A, they effectively only give information on the population level during that period, not during Middle Bronze Age B. So all in all, the number of Middle Bronze Age barrow erected per century need not have been that much smaller than the number of Late Bronze Age urnfields erected. And what is more, barrows actually only give information on the population level of the period 1900-1400 BC, not of the period immediately preceding the Late Bronze Age. In fact, if we compare the settlements traces from the Middle Bronze Age B and the Late Bronze Age, we see that the evidence from the latter period is extremely poor compared to that from the previous period (cf. Fontijn & Fokkens 2008, 359). So there appear to be no strong indications for a considerable rise in population level until the beginning of the Early Iron Age, when both the number of urnfields and settlements appear to be considerably higher than before. 98 A second problem with Gerritsen’s model concerns the supposed relocation patterns of farmsteads and accompanying fields. According to Gerritsen the pattern of residential mobility became spatially more restricted through time (2001, 202-3, 254). However, it is unclear on what evidence Gerritsen bases himself when he characterises the Middle Bronze Age settlement pattern as being very flexible. And the same goes for Roymans and Kortlang (1999), on which Gerritsen appears to base himself again (2001, 202-3). For the Middle Bronze Age it is basically unknown at what time-interval farmsteads were relocated, over what distance they moved and how they spatially related to agricultural fields (Arnoldussen 2008). And neither is this known for Late Bronze Age farmsteads, as only a few of these are known (see paragraph 5.3.1). In fact, these aspects are not even known with any certainty for the Iron Age. The development of the Celtic field agricultural system in the Late Bronze Age appears to be part of Gerritsen’s argument for a decreased spatial range of patterns of residential and agricultural mobility in the Late Bronze Age (2001, 256). Celtic fields are co-axial field systems that mostly take the form of extended clusters of square and rectangular fields separated by low earthen banks. For the Iron Age it is known from excavations that farmsteads were located in or near these field systems. These would have shifted periodically within these arable lands, resulting in a system in which the fields near the farmstead were in use while other parts of the Celtic field complex lay fallow for long periods of time (Gerritsen 2001, 180-93). According to Gerritsen (2001, 256), such a system would have resulted in a spatially more restricted residential pattern compared to that of the Middle Bronze Age. However, our knowledge of the Celtic field system is very meagre. We know almost nothing of the residential patterns within the arable complex, we also do not known how the clusters of fields were formed and, of course, we do not know how (much) it differed from Middle Bronze Age field systems (Gerritsen 2001, 180-93). More importantly, we do not even know when the celtic field system first came into existence. Usually the rise of the systems is associated with a supposed demographic increase and therefore a Late Bronze Age date is proposed – but as we have seen there is no conclusive evidence for such a rise in population level in the southern Netherlands. And this date is never confirmed by evidence from Celtic field research (Gerritsen 2001, 180). So the system might also have originated during the Early Iron Age (or perhaps even later). All in all, the development of the Celtic field systems is not a valid indicator of a more spatially restricted residential pattern in the Late Bronze Age. Combined with the lack of knowledge on Middle Bronze Age residential model, suggestions on developments of residential mobility from the Middle to Late Bronze Age can only be tentative. 99 The third problem of Gerritsen’s model of the genesis of urnfields concerns the development of a mythical geography. According to Gerritsen (2001, 254) the infill of the landscape with barrows through time would have resulted in an increased interaction with the historical and mythical dimensions of the land which through time led to a closer association of social groups with particular parts of the landscape. However, Bourgeois and Arnoldussen (2006) have shown that most barrows were constructed before 1400 BC and so the majority of the historical and ancestral markers of the mythical geography would already have been present at the beginning of the Middle Bronze Age B. But it is not until the end of the Middle Bronze Age that social groups became associated with parts of the land so strongly that this relationship found expression in fixed burial places, the urnfields. How does one explain this time lag of several centuries between the formation of the mythical geography and the sudden large scale expression of the relation between people and the land? Summarizing, there is no firm evidence for a rise in population level and an accompanying infill of the landscape, neither is there for significant changes in residential mobility from the Middle to Late Bronze Age, and the elements for a mythical geography with which communities could be associated were already present several centuries before the start of the urnfield period. So obviously there are no indications for a process leading to a more sharply defined territorial organisation and an increased social integration at the end of the Middle Bronze Age, as there does appear to be for the Early Iron Age. Rather than being the outcome of such a process, urnfields, as the first fixed symbols of the identity of a local communities, might just as well been instrumental in such a process, that would then have started with the coming of the first urnfields and culminated in the Early Iron Age. So a supposed increased desire to express collectivity need not have existed at the start of the Late Bronze Age. Nonetheless, I do agree with Gerritsen that above all urnfields do seem to express such collectivity (2001, 255). Fokkens stresses a process of individualisation as reflected by each person receiving its own barrow burial in urnfields. However, as explained in chapter 4, the dense layout of small barrows and the uniformity in burial practices and monument form to my opinion mostly express a sense of communality (cf. Gerritsen 2001, 255). But how does this differ from the values expressed through Middle Bronze Age barrow rituals? Of course a major difference is the inclusiveness of the burial rite. While urnfields appear to contain the remains of almost all members of a society, only a selection of the Middle Bronze Age population (10-15%) was buried in barrows (Gerritsen 2001, 150-1). And whereas for urnfields it is reasonable to assume that the burial community consists mainly of the members of the local community living in territory around the cemetery, the composition of the burial 100 community of barrows is unknown. For long it was thought that Middle Bronze Age barrows were erected in the vicinity of a house for the burial of a family head of the household and his descendents (Fokkens 2003). They were supposed to be ‘family barrows’. However, a survey of published burial mounds by Bourgeois and Fontijn (2008) has shown that most barrow contain far fewer burials than there would be members of a household. Also, there is no indication for the Southern Netherlands that the selection of the person interred in the primary barrow grave was based on age, sex or a high social status (Fontijn & Cuijpers 2002, 176). And neither does there appear to be such a selection criteria for secondary burials (Fontijn & Cuijpers 2002, 174; Theunissen 1999, 98-100). So apparently selection for a barrow burials is based on other criteria than ‘status’: like with urnfield burials it is not the identity of the individual that seems to be stressed during the barrow ritual. Rather barrows contained the remains of people from all age groups and all sexes. It might therefore very well be that the Middle Bronze Age barrow, as a collective grave, symbolized a social entity like a household (cf. Fontijn & Cuijpers 2002, 174; Bourgeois & Fontijn 2008, 43). Often Middle Bronze Age barrows were re-used, so there appear to have existed a preference for continually burying the deceased at a fixed place: apparently “the barrow and the dead buried in it, was itself seen as an important entity with which people could identify. In the continual re-use of the barrow, ties between the burial community, the deceased person and the world of the ancestors, represented by the older graves, were reaffirmed. In it a group defined itself as a collective, rooted in an ancestral past” (Fontijn & Cuijpers 2002, 177). The notion of a burial ground as a symbol of the collective, however this collective was defined and the link between this community and the burial ground was conceptualised, may therefore have been nothing new when the first urnfields came about. 5.3.3 Bronze Depositions The notion of collectivity, as we found it being expressed at burial grounds, also appears to have been significant at the ritual deposition of bronzes in the Middle and Late Bronze Age. The practice of bronze deposition is widespread in Bronze Age Europe. For the southern Netherlands it has recently been extensively studied by David Fontijn (2002). The insights gained in his study on the value system of Bronze Age communities in this region will be summarized here (also Fontijn 2008). Let us start with a general overview of the characteristics of the system of bronze deposition as practiced in the southern Netherlands. The most salient feature of this system is that it is a form of selective deposition: specific kinds of objects were deposited in specific kinds of places. In general, the deposition of metalwork that was intended to be permanent involved 101 placing a bronze object in an unaltered, watery location. Certain distinct patterns can be discerned: 1. Axes, sickles and weapons were not deposited in graves, but elsewhere. 2. Swords were deposited predominantly in major rivers. 3. Metalwork deposition on farmyards or in houses occasionally took place, particularly of sickles. 4. Lavish ornament and dress items of a supra-regional style were deposited in wet or semi-dry location, while local or inconspicuous items tend also to be deposited in graves. The most common kind of deposition is that of a single item; multi-object hoards are rather rare. The deposited objects in general show signs of having been used and were imported items. Apparently the life-path of the objects mattered, and a life in exchange networks seems to have been important. These objects were generally deposited in a well-preserved state, some weapons even being sharpened before deposition. An important aspect of these depositional practices is that they are highly conservative. The patterns observed seem to have been maintained in more or less the same way from the beginning of the Middle Bronze Age to the end of the Late Bronze Age: a period of a thousand years. What did change was the frequency in which deposition occurred. After being a rare practice in the Early Bronze Age, bronze deposition became more regular in the Middle Bronze Age A, gradually increasing throughout the Bronze Age to finally conspicuously peak in the Late Bronze Age. Let us now see what the implications are of such a system of selective deposition. The fact that specific kinds of objects were deposited in specific kinds of places suggests that these items were considered not comparable because they carry specific and different meanings. Such meanings come about through the life-path of the object. And indeed, the deposited objects show signs of such a use-life and a life of circulation. This suggests that the objects did not carry special meanings from the beginning but that these resulted from their biographies. Many of the deposited items are objects that are instrumental in marking the life stages of individuals and signal social roles and statuses. The biography of items as body ornaments, dress fittings and weaponry should therefore be seen as related to the construction of personal identities. Significant in this regard is a distinction between two kinds of depositional contexts: burials and unaltered places. Although the items are all related to a personal identity, the nature of this relation differs between burials and unaltered places. In burials the deceased is decorated and equipped with bronze items and thus a particular kind of person is created. However, deliberately removing the 102 same kind of objects by sacrificing them at unaltered implies the de-construction of a kind of identity. So what kinds of items were deposited in burials, then, and what kinds of item at unaltered places? A first category of bronze objects found at unaltered places is weaponry. A second category consists of ornaments of a non-local style. Both categories of exotic items represent values that were probably considered ambiguous, namely martial identity, warfare and the supraregional. Weaponry can be considered ambiguous because from a socio-political perspective it implicates the unequal distribution of power and authority, while from a moral perspective the use weapons can be considered a polluting act as it involves the transgression of the boundary between life and death. This conflicts with the collectivity that is expresses at barrow groups and urnfields (see chapter 4). Also, the weapons depict a kind of imagery that was shared over several regions, as do the ornaments in supra-regional style. It suggests a reality in which a local group is part of much wider, social whole. A reality that might be ambiguous as it represents the dependency of the local group on factors beyond their control. It is these categories of bronze objects – and the values they represent – that are kept from burials. In Middle Bronze Age burials metals are almost absent, while during the Late Bronze Age only simple ornaments were deposited according idiosyncratic norms and ideas, thus stressing above all a local identity. So apparently different, conflicting values were expressed at different places: martiality and membership of supra-regional exchange networks at one context, and localism and collectivity at another. So what does such a system of selective deposition bring about then? As explained, all the items deposited at unaltered places are of an ambiguous nature. They contest the collectivity and egalitarity of the local community. Such ambiguity should be dealt with. As so many of these items end up at unaltered places deposition apparently is a means to align these ambiguous, foreign items with the moral order of the local community. Through the deposition ritual the meaning acquired by the items is celebrated for the last times, and then de-constructed by exchanging them with the local landscape from which the communities derived the important sense of belonging. Thus the items are recontextualised. 5.3.4 Conclusion Fokkens (1997) has suggested that the genesis of the urnfield burial ritual in the Southern Netherlands is a logical outcome of a process of individualisation that must have started at the end of the Middle Bronze Age, as indicated by evidence on settlements, bronze exchange and burial ritual. However, I have shown that evidence for the splitting of extended into nuclear 103 families, as indicated by diminishing farmstead lengths, does date earlier than the end of the Late Bronze Age. The bronze exchange network might indeed have opened up to a larger group of people at the end of the Middle Bronze Age, as the significantly increased amount of bronze deposited during the Late Bronze Age suggests (Fontijn 2002, 257). However, we have seen that patterns in bronze deposition suggest that the personal identities acquired through these exchanges, such as martial identities and belonging to a supra-regional community, were socially and morally circumscribed. Especially during the burial ritual they found no expression. Also, I have suggested that individualism as reflected in urnfields by each person receiving its own barrow burial in urnfields is outdone by the collectivity as expressed through the uniformity of the ritual. So instead of individualism it rather appears to be collectivity that was a central value, at least when it comes to the burial rite. And this sense of collectivity was not restricted to the uniform urnfield rituals, but also the Middle Bronze Age barrow ritual seem to have given little expression to the person as an individual, as age, sex or high status appear not to have been selection criteria for inclusion in the barrow burial community. However, indications for an increasing sense of communality or a desire to give expression thereof at the end of the Middle Bronze Age, as suggested by Gerritsen (2001), appear to be absent. There is no conclusive evidence for a rise in population level, a decreasing residential mobility or a closer association of local communities with parts of a historical landscape. Besides the collective other values were evident in the Bronze Age society of the Southern Netherlands. The regularity and monumentality found in Middle Bronze Age houses denounce the social and ideological significance of the household. This regularity of the house is part of a wider sense of traditionalism that appears to characterise the Middle Bronze Age B cultural landscape, as shown by the clustering and frequent re-use of barrows and a structured system of metal deposition at natural places (Arnoldussen & Fontijn 2006). One can easily see how the spatially fixed urnfields are in accordance with this regularity and order of the late Middle Bronze Age landscape. 5.4 Material Constraints: Subsistence & Ecology The subsistence strategy of the Bronze Age communities of the southern Netherlands is characterized by a system of true mixed-farming as defined by Louwe Kooijmans (1993), that is, a system of combined and interdependent crop cultivation and livestock rearing. Amongst this livestock cattle dominates (60-80%), with sheep and pig following in smaller quantities (Arnoldussen & Fontijn 2006, fig. 8). The main staple was cereal crops, with barley and emmer 104 wheat being the most common species, supplemented by bread wheat and millet. From the Late Bronze Age onwards spelt and flax were also part of the staple (De Hingh 2000; Van Wijngaarden-Bakker & Brinkkemper 2005). This will incidentally have been supplemented by wild game, fish, fowl and collected natural sources (Arnoldussen & Fontijn 2006, fig. 8). Of the latter charred acorns are often retrieved and incidentally sloe prunes, raspberries and wild apples. There are no indications for significant changes occurring in the diet from the Middle to the Late Bronze Age. So let us take a look at the conditions of the land that provided this diet. The Bronze Age landscape of the Southern Netherlands (and Northern Belgium) is characterized by gently undulating cover sand ridges, crosscut by streams and marshes. These streams and marshes divide the cover sand area into numerous small and large plateaus. The cover sand ridges are mostly low and elongated, following a general southwesterly to northeasterly direction. The flow of the streams is mainly determined by the orientation of the ridges. Due to minor differences in elevation of the area and the barriers formed by some cover sand ridges, some areas are poorly drained leading to the formation of marsh and peat areas. Beneath the 0,5 to 1,5 m thick cover sands the subsoil consists of coarse sediments of precursors of the rivers Meuse and Rhine. In the Peel area these sediments surface as the result of tectonic processes. Drainage is thereby hindered and an extensive peat area had formed in this area in the Bronze Age, forming an inhabited zone between the Meuse valley in the east and the western cover sand plateaus. In the northern and northwestern border area of the study area peat and marine clays dominate. All in all, the Bronze Age landscape of the Southern Netherlands was a differentiated whole consisting of wet and dry zones with slight differences in elevation (Gerritsen 2001, 27-9). Mineralogically the sandy soils of the south are rather poor with limited natural fertility, while precipitation surplus contributes to the eluviation of minerals from the top soil. The result is vulnerability for soil degradation as it is a situation in which podzolisation can take place: the process of humus elements and iron oxides leaching from the top soil and being deposited at a lower level. Podzolisation on sandy soils is affected by the loam content of the soil, the vegetation cover and human activities. When the loam content of the sandy soil does not exceed 10% podzols will be formed notwithstanding the type of vegetation cover. The soils thus formed are so-called ‘primary podzols’. Whether soils with a loam content between 10 and 20-25% will or will not podzolise, does depend on vegetation cover, hydrological conditions and the amount and type of humus entering the ground. Human activities like crop cultivation and forest clearing can have a profound impact on these latter conditions and in the long run cause accelerated podzolisation. This might result in ‘secondary podzols’. In soils with a loam content higher than 105 20-25% podzols are unlikely to develop. The most common type of soil type now current on the sandy soils of the southern Netherlands is the humus podzol, which consists of both primary and secondary podzols. However, these soils have, of course, developed through time and it is unclear to what extent the present situation compares with that of the Bronze or Iron Age (Gerritsen 2001, 214-5). It is probably fair to assume that by the beginning of the Bronze Age most primary podzols had already formed in the sandy soils, as the conditions of a climate with precipitation surplus had already existed since the early Holocene. The question is therefore to what extent secondary podzolisation had taken place by the beginning of the urnfield period. Palynological investigation of barrows from the Late Neolithic and Bronze Age have shown that from the beginning of the Bronze Age onwards gradual heath land expansion took place in the sandy areas of the southern Netherlands. Such acid heather vegetation is typical for humuspodzols. Forest generation did take place, however, and the heath lands probably remained limited in size. Palynological evidence from urnfields, on the other hand, show that these cemeteries were laid out in an increasingly more open landscape (Gerritsen 2001, 242). It is generally assumed that during the urnfield period an acceleration of soil degradation occurred as the result of the mentioned forest clearance (leading to increased water flow and secondary podzolisation), the intensive Celtic field agricultural system, and a rising population level (Gerritsen 2001, 243). In time this degradation process led to the reaching of a threshold at the end of the Early Iron Age and the beginning of the Middle Iron Age, after which habitation on the sandy soils had to be given up. (Gerritsen 2001, 243). However, in the last paragraph I have explained that there is no conclusive evidence for an increasing population level or an intensifying agricultural regime from the Middle to Late Bronze Age. So we only have palynological evidence indicating a gradual opening of the landscape during the Bronze Age and especially during the urnfield period. But to what extent this have led to significant material constraints during the Middle and Late Bronze Age is for now impossible to assess. As forest clearance apparently still took place during the Middle Bronze Age the effects of soil degradation would probably have been limited. 5.5 Demography & Population Structure In this paragraph I will reconstruct the demography of Middle and Late Bronze Age southern Netherlands at different levels and see how the population is structured in different social groups and communities. At the smallest social scale we have the household. Many authors have tried to estimate the number occupants of Bronze Age houses. Three methods have been used to come at 106 educated guesses of household size: using correlations between living floor area and number of occupants based on cross-cultural comparisons, using historical analogues and census numbers, or establishing the maximum nutritional capacity of fields or live stock. The estimated household sizes range between 5 and 20 people, but, of course, none of these methods provide us with conclusive numbers (Arnoldussen 2008, 86). Besides, for the Middle Bronze Age the correctness of these numbers depends on whether or not a part of the house was in use as a byre-section. At a larger scale we have the settlement or local community. For the Middle Bronze Age estimates of local group sizes are as tentative as those of household sizes, as they are often nothing more than fair guesses or multiplications of the assumed number of households that make up a local community. In general, the estimated sizes range between 10 and 30 persons (Arnoldussen 2008, 86-7, table 3.6). For the urnfield period, however, we have a more firm base for estimating the size of local communities: the urnfields. When the total number of burials, the average live expectancy of the population, and the period of use of a burial ground is known, one can calculate the approximate size of the local community. An important requisite is, however, that the entire community is buried at the same cemetery. For the Dutch urnfields this is assumed to be the case, as the cemeteries consists of many burials in which all age classes and sexes are represented. Only the youngest children, those younger than 2 years old, appear to be underrepresented. However, this can be corrected in the calculation by adjusting the average live expectancy of the burial community (Hessing & Kooi 2005, 647-8). Also, not all urnfield burials appear to have contained one individual (see Theuws & Roymans 1999). However, for most excavated urnfields physical-anthropological analyses of the human remains has not been carried out, so the estimations of community size based on these urnfields will be a bit low (cf. Fokkens 1997, 363). On average the estimated size of local communities in the urnfield period ranges between 5 and 25 people (Hessing & Kooi 2005, 648-9). This roughly corresponds with the community size estimated for the Middle Bronze Age. Such a community would then consist of 1 to 2 households in the Bronze Age or of about 4 Early Iron Age households. If we have an estimate for community size we can also estimate the general population size of the southern Netherlands if we know how many communities existed at a time. Estimating the number of communities during Middle Bronze Age is hard, however. As settlements are hard to define and relatively little traces of them are known, we have to use the distribution of barrows and barrow groups to infer the density of habitation. But as we have seen earlier (paragraph 5.3.2) it is hard to evaluate the representativity of the current barrow distribution. And more importantly, we do not know how barrows spatially relate to settlement territories and 107 conceptually relate to local communities. Estimating population size from barrow distribution is therefore impossible. For the Late Bronze Age (and Early Iron Age) it is generally assumed that each urnfield is the burial ground of a local community inhabiting a territory marked by this urnfield (Gerritsen 2001; Hessing & Kooi 2005, 649). The approximate size of these local communities have been estimated, so all that is needed is to know the total number of urnfields in order to calculate the population level for the Late Bronze Age. In chapter 3 it was shown that I have inventoried a total of 23 urnfields with conclusive evidence for Late Bronze Age activity, while Gerritsen (2001, appendix 2) has dated another 39 Dutch urnfields to the Late Bronze Age on slightly different, less strict criteria. His catalogue also contains 76 sites that could not be dated more precisely than the entire urnfield period (these numbers exclude the sites from the Belgian part of Gerritsen’s research area). Gerritsen (2001, 233-7) also estimates that in the total Meuse-Demer-Scheldt area about 200 urnfields have been destroyed without documentation or still lie beneath essen soils. As with the known urnfields, most will have lain on Dutch soil. Let us say 125. So in total we have about 240 urnfields that might date to the Late Bronze Age. But what fraction of these really do date to this period? Of the 188 urnfield in Gerritsen’s inventory that could be dated, I dated 23 to the Late Bronze Age while Gerritsen dated 62 to this period - that is 12 to 33%. Early Iron Age burials are, however, more easily recognized than Late Bronze Age interments, as amongst pottery from this period there are two very distinct types: the Schräghalsurne and the pottery in Harpstedt style. So I guess it is a fair estimate to say that of the 240 undated urnfields perhaps as much as 40% or 96 urnfields belong to the Late Bronze Age. With the 23 urnfields that could be conclusively dated to this period, this comes to a total of 119 Late Bronze Age urnfields (mind that this number applies to the Dutch part of the Meuse-Demer-Scheldt area only). If we assume that to each urnfield belongs a community of 5 to 25 people, the total population of Late Bronze Age southern Netherlands ranges between 595 and 2975 persons. Now let us see how this Bronze Age population was structured. As explained in chapter 2, singling out different kinds of groups and communities is important, because it is to be expected that cultural evolution is driven by different forces and/or proceeds in different directions within each of the subpopulations present. We already came across two communities, that of the household and that of the settlement or local community, but many more communities probably existed. The constellation of communities was probably fluid and dynamic: a person could belong to several communities, such as a household, a local community, a sacrificial community, a kin group, an age group, etc. and such relations probably shifted depending on, 108 amongst other things, context, time, and condition of the individual. But, of course, what we are really interested in is the nature of the burial community. We already saw that during the urnfield period the people being buried at a cemetery were probably the members of a single local community. For the Middle Bronze Age the physical and conceptual link between barrows and the local community is less clear. But a burial community is, of course, made up of more people than the buried – there are of course also the buriers. And establishing who these buriers, or mourners, are is even more difficult than establishing who the buried are, as the former leave virtually no archaeological traces. Nonetheless, it is essential for the current study to get a general idea of who the mourners are, as it are these people that spread the cultural ideas on burial rites. Theoretically the group of mourners can consist of three kinds of persons: people guiding the burial ritual, people executing it, and onlookers. During different stages of the ritual the composition of this group might change, with people switching roles and perhaps leaving or entering the community of mourners. Stages of the ritual of which we have direct of indirect evidence from Bronze Age burial grounds (and therefore those of which we can study the spread of associated variants) are: -producing and selecting objects that act in the burial rite; -selecting location for burial; -choosing between inhumation and cremation; -building pyre; -laying out body and items on pyre; -burning of body; -collecting remains from the burned pyre; -selection and creation of burial structure (pit, tree-coffin, etc.); -depositing remains and grave goods; -constructing mound body; -selecting and creating peripheral structure of barrow; -ceremonies conducted after burial. One can imagine how the composition of the group of mourners differs between these stages. The selection of grave goods, burial location and body treatment (inhumation vs. cremation) may, for instance, have been done by the direct relatives of the deceased together with a ritual authority like chief or shaman, possibly without any onlookers. The building of the pyre and the construction of the mound and its peripheral structure may perhaps have been done by the 109 (representatives of the) different households of the local community to which the deceased belongs, under the eye of a large group of spectators. Interring the remains and grave gifts may, on the other hand, have been a rather intimate act, of which the details were perhaps only visible to those directly involved. These are of course mere speculations and the exact details of who did what will probably never be known and do, in fact, not concern us here. What is important to realize, is that there are three groups with their own ‘cultural fitness’, their own abilities to affect the type and frequency of ideas or cultural variants present in a population. First, there are the onlookers. During the burial ritual these have least influence on the cultural variant as they can only observe the ritual and not affect its execution. Whether onlookers were present during Bronze Age burial rituals is at present unknown, as evidence in the form of, for instance, large feasts have not been found. It is therefore possible that burials were a private affair. However, it is likely that spectators were present, as they are at burials in most present-day societies. Also the location of both barrows and urnfields suggest that burials were a public affair, since they are often located at fairly accessible or sometimes even conspicuous places. For both it has even been suggested that they are located along roads (Drenth & Lohof 2005, 433; Hessing & Kooi 2005, 645). This in contrast to the inaccessible, unaltered places where bronzes were deposited (Fontijn 2002). The presence of onlookers is also to be expected if the Bronze Age burial rite had the social function of expressing the ancestral relation between a community and the land, as is often assumed (Gerritsen 2001). Such a message would clearly be less potent without spectators. So spectators are likely to have been present and this group would probably have consisted at least of most members of the household and local community to which the deceased belonged. Also present were probably certain members of wider communities, such as the exchange or trade network to which the deceased (or his near relatives) belonged, the wider religious community (Gerritsen 2001, 175-9) and wider kinship relations. The second group consists of the people executing the burial rituals. In contrast to the onlookers, people from this group do have the ability to alter the cultural variant. One can imagine how people during the execution of ritual might have options. While the course of certain parts of the ritual might be strictly stipulated by tradition and religious consideration, others parts may allow more room for personal infill. Sometimes the executioners might even have altered the course of the highly traditional aspects out of personal considerations. Those people executing the ritual were probably those nearest to deceased, the members of the household, kin group and the local community. These are the same people that at other funerals were the onlookers. Members of society that were deemed important, such as kin group elders, probably figured most promptly 110 during these rituals. This means that for most part the transmission of ideas on the right conduct of a burial rite took place amongst a small group of persons. Some parts of the ritual were perhaps carried out by a particular specialized group of people. For instance, in modern-day Hindoe societies of India, the burning and handling of the corpse is done by people from a particular caste, as it is considered an impure act. The persons with the highest cultural fitness are those guiding the ritual: the religious authority. As these people create or at least proclaim the right course and traits of the ritual, one can imagine that they, knowingly or unknowingly, have considerable opportunities to maintain or alter it. I will discuss the nature of authority in the Bronze Age in the next paragraph. 5.6 Social Constraints: Authority & Influence For many areas in Bronze Age Europe evidence for the existence of a social stratification is thought to be present. For instance, in Southern Scandinavia Earle (1997; 2002; 2004) and Kristiansen (1984; 1998; 2001; Kristiansen & Larsson 2005), see the presence of chiefs attested in burial and settlement evidence. Several arguments are presented by these authors. First, the burial evidence indicates the existence of two social classes: chiefs who were buried with fragile, lavishly decorated, unused flange-hilted swords, and warriors that were buried with more solid, battered solid-hilted swords. Secondly, the settlement evidence shows the existence of farm houses of unusual size – supposed chiefly halls. Thirdly, it is assumed that the intensification of life stock rearing would have led to a tradable surplus that allowed chiefs to access and control the exchange and production of bronzes, the redistribution of which sustained warrior retinues. Lastly, the burial ritual displayed social stratification by chiefs being buried in large barrows with more and more lavish grave goods than warriors. These arguments have recently been assessed by Arnoldussen (2008, 433-7) and considered whether they also apply to Dutch Bronze Age societies. I shall shortly repeat his conclusions. Notwithstanding the apparent presence of two types of persona being constructed during mortuary rituals – that of the warrior and the chief – Arnoldussen (2008, 433-4), to my opinion correctly, doubts whether this indeed reflects two social roles. Starting from the dictum that the dead do not bury themselves, he explains that grave goods might not be a direct reflection of personal ownership and social categories, but rather of an identity (real or ascribed) communicated by the bereaved. The traditionality found in the grave good set could therefore indicate a long-term tradition of stressing a specific identity. Solid evidence for martiallity being a full-time affair in the Bronze Age is, in fact, absent. Fontijn (2003) has explained that weaponry, or rather the values it represents, such as martiallity and belonging to a supra-regional 111 community, might, in fact, have been considered ambiguous as it contests the moral order (see paragraph 5.3.3). Warriorhood might therefore, at least in the Netherlands, have been a temporary identity that was ritually and socially circumscribed. In the southern Netherlands burials containing weaponry and/or lavish bronzes are in fact absent, as we saw in our discussion on bronze deposition (paragraph 5.3.3). Here weaponry is known from ritual deposits at unaltered places. Fontijn (2003, 230) interprets these as deposits made at transitions of social roles, which took place for instance at a certain age of the bearer or after weapons had been used during a battle or raid. Depositing the weapons at unaltered places deconstructed the identity and recontextualised the items and the values they stand for with the moral order (see paragraph 5.3.3). So obviously it is not the martial values expressed through weaponry that should be doubted – armed violence was a part of the Dutch Bronze Age society as attested by mass-burials and use-wear on weapons – but rather the notion of warriorhood as a full-time affair. The second strand of evidence to consider is that from settlement sites. In southern Scandinavia several houses have been found that fall beyond the normal size distribution (Arnoldussen 2008, 435). These have been interpreted as the residences of chiefs. However, as Arnoldussen (2008, 435-7) notes, the houses are indeed of abnormal size, but it is unclear whether they are extremes of a continuous distribution or indeed represent a different class of house. Their large size may have been the result of a compartmentalized construction history and the presence of hearth, pits and stalls in large houses from Swedish sites suggests that the function of these houses did not differ from smaller examples. Indeed, other than their size, there is no evidence to suggest that the occupants have been of higher social rank. And neither is there for the Dutch longhouses of which also several large examples are known. Also, like the Scandinavian houses, the Dutch examples do not show a bimodal but a continuous distribution in size. Neither is it evident that these houses sheltered a larger livestock; the supposed surplus with which the chief could enter exchange networks. Indeed there is no evidence that livestock size or composition differed significantly between Dutch Bronze Age settlements. So, while houses may indeed have communicated messages about the social status of its residents, there is no conclusive evidence to suggest that they are or are not the residence of chiefs. In conclusion we can say that neither evidence from settlements nor that from burial sites provides conclusive indications for the presence of a social class of chiefs or warriors. This, of course, does not mean that the Bronze Age society of the southern Netherlands was an egalitarian one. Social stratification was probably present, but it is the basis, duration, extent and exclusivity of this authority that is unknown. For the moment, any suggestions on these matters would be 112 mere speculation. One kind of authority does need some further discussion, though, as it is vital for this study: the religious authority. As explained in the last paragraph, the religious authority guiding the Bronze Age burial rituals is the kind of person with the highest cultural fitness and therefore a vital part of the process of culture change. However, evidence on the nature of such an authority in Bronze Age Netherlands is lacking. In fact, we do not even know whether any religious authority existed. But as in most societies a religious authority in the person of a priest or shaman does exist (Hicks 2010), it is to be expected that it also did in the Bronze Age. And in fact, for the Nordic world Kristiansen and Larsson (2005) have formulated very specific ideas on the nature of such an authority. They are, actually, one of the very few who have given thought to the nature of religious authority in Bronze Age Europe. In Scandinavia they see evidence in burials, settlements, bronze deposits and iconography for the presence of a priestly chief. What they have found is paraphernalia and symbolism known from Near Eastern and eastern Mediterranean cultures. In the cultures paraphernalia and symbols signal a chief who is also a ritual leader. This priestly chief is part of an institution of dual leadership, with a warrior chief as its political counterpart – a socio-political implementation of a wider religious structure of Twin Gods. As it goes too far to assess the correctness of this interpretation for the Nordic world, it may suffice to say here that we have no evidence that indicates a similar institution existed in the southern Netherlands during the Bronze Age. It is to be expected that an intimate relation existed between religion and politics, as it generally does in ‘primitive’ societies: “If by politics we denote those behavioural processes of resolution of conflict between the common good and the interests of groups by the use of or struggle for power, then religion in [primitive] societies is pragmatically connected with the maintenance of those values and norms expressing the common good and preventing the undue exercise of power.” (Turner 2010, 147-8). Both ritual and political leaders have a major stake in how society is constituted and the action of both affect the moral and cosmological order. However, the nature of this relation between political and religious authority remains unknown for the Bronze Age of the southern Netherlands. So what kind of religious functionaries can we expect to have been present in this society? In anthropology and sociology a distinction is generally made between priests and shamans. The main difference between these is that shamans acquire their status through personal communication with super-natural beings, whereas priests have competence in conducting ritual without necessarily having a face-to-face relationship with the spirits. The institution of the ritual intervenes between the priest and the deity (Turner 2010, 140-1). This distinction results in two different kinds of operation. “The priests preside over a rite; the shaman or medium conducts a 113 seance. Symbolic forms associated with these occasions differ correlatively: the symbols of a rite are sensorily perceptible to a congregation, while those of a seance are mostly in the mind of the entranced functionary as elements in his visions or fantasies and are often generated by and limited to the unique occasion.” (Turner, 141). Although the distinction between chief and shamans may perhaps not always have been as easy and clear-cut as present here, it is important to make this distinction for prehistoric societies – something which is almost never explicitly done for Bronze Age Europe (see for example, Kristiansen & Larsson 2005 – because the sociocultural correlates of these two types of religious functionaries differs significantly. Priests are mainly concerned with the conservation and maintenance of a deposit of beliefs and practices that were handed down from the founders of the social or religious system. They can be seen as actors in a culturally “scripted” drama. Only rarely do they radically innovate in religion. If a priest does so, (s)he likely becomes a prophet to followers and a heretic to former peers. So a priest actually keeps cultural change and individual deviation within narrow limits. The shaman and prophet, on the other hand, are less bound up with the maintenance of the total cultural system. They are more sensitive and responsive to the private and personal. This type of functionary is likely to be found in loosely structured cultures, dealing individually with specific occasions of trouble, or during period of social turbulence and change, when societal consensus about values is sharply declining and large classes of people are becoming alienated from the current social order (Turner 2010, 141-2). What is more, ethnographic examples show that during funerals shamans have little concern for the proper conduct of the ritual – mostly they are centred on the welfare and proper passage of the spirit of the deceased (Hicks 2010). So did the religious authority in Bronze Age southern Netherlands lie with institutional or inspirational functionaries? Unfortunately, we have no direct evidence to distinguish between one or the other. We can, however, try to deduce it from the kind of society present in Bronze Age and the kind or rituals performed in it. Cross-cultural studies show that often where there is a priest the shaman is absent, and the other way around. Shamans tend to predominate in loosely structured, food-gathering societies, where they perform rites for the benefits of one or a few individuals and within the context of an extended family group. Priests are mostly found in structurally elaborated food-producing societies – usually agrarian societies – performing public rites for the benefit of a whole community (Turner 2010, 140). As we saw, these rites were highly traditional and involved conspicuous symbolism and acts perceptible by a congregation. Bronze Age society can probably be best characterised as the latter. Rituals in many parts of Europe appear to have been public (Bradley 1998) and highly traditional, with a widespread and perspicuous symbolism (Kristiansen & Larsson 2005). And although the nature of the structure of 114 European Bronze Age societies remains a matter of debate, a rather elaborate structure is apparent (Kristiansen 1998). So the presence of an institutional religious functionary – a priest – seems to be the most likely for Bronze Age societies. In terms of social constraints, the priest, together with the political leader, has several advantages over the commoner. Firstly, they are figures of authority. This gives them the means to force their ideas on others, by force, threat, persuasiveness, etc. Especially the role of religious authority will have been important in the spread of ideas on burial rites, as such rites belong mainly to the sphere of influence of this authority. Secondly, the political and religious leaders are often public figures with personal charisma. However this charisma is defined (the individuals could be deemed successful, prestigious), it brings about a predisposition amongst commoners to imitate them. Amongst the religious and political leaders there have probably also been differences - priests have more authority during rituals than political leaders, and some political leaders are more charismatic and have more power than others. 5.7 Communication: Modes of Transmission In the last two paragraphs we have determined which groups were involved in the transmission of the ideas behind Bronze Age burial rites. In this paragraph we will look at the routes of transmission – who communicated with whom on these notions – and the means of transmission – through what media did people communicate. As there is virtually no evidence on these matters, a theoretical model will be created in the following. 5.7.1 Routes of Transmission We established that during a burial three groups were present: onlookers, practitioners and religious functionaries. These are also the people involved in the transmission of the ideas, or cultural variants, behind the ritual practices. In terms of cultural transmission the onlookers and practitioners belong to the same group. While a person may be an onlooker at one funeral, he or she may be a practitioner at another funeral. And this already shows the main route of transmission amongst this part of the burial community: at one occasion a person observes an example of proper conduct (he or she is the transmittee), while at another occasion that same person sets the example (he or she is the transmitter). So people learn by observing others. Another way to transmit ideas on proper conduct and associated values is through the teaching of younger members of a society by an elder generation (parent, grand-parents and/or other elders of the kin group or community) and/or a priest. 115 So it appears that within the group of onlookers/practitioners there are several modes of transmission (table 2.1). People learn by teachings from one or a few elder relatives (vertical transmission) and by observing peers during multiple rituals (horizontal transmission). However, it is likely that most members of the burial community insist on the proper, traditional conduct of respectful practices. So here we have a large group of people (onlookers, leaders and religious functionaries) uniformly affecting the practice of the individual practitioner. In effect, this is a form of concerted or many-to-one transmission. In this kind of transmission innovation is accepted with much difficulty and variation between individuals and groups is low. People also learn trough the teachings, preaching and rituals of religious functionaries. In these cases it is a single individual or a few individuals who disseminate ideas to an audience or a group of pupils: one-to-many transmission. Technically it is impossible to have one-to-many transmission in a situation where people also learn from elders and peers, because this form of transmission presupposes only one teacher. Strictly, the religious functionary is just one of several peers from which a person learns during rituals. However, because of the prominent role the functionary plays during ritual and because of his ritual authority, this functionary is probably much more influential than other peers. And as most members of the burial community probably only know one are a few priests during their life, I think we can speak of a one-to-many relation between the priest and the burial community. A similar relation probably also exists between the most influential political leaders and the community. With this kind of transmission, like with the many-to-one transmission, cultural variation is generally low between individuals. Innovations are, however, much easier accepted with this kind of transmission, as innovation by the teacher means almost instantly means innovation by a large group (Shennan 2002, 48-51). Yet, when information is transmitted by a priest such easy acceptance of innovations will only happen when the innovation concerns less traditional elements of the ritual or when a priest becomes a prophet in a situation of social change or turbulence (see paragraph 5.6). The other group that make up the burial community, besides the onlookers and those conducting the ritual, are the religious functionaries. We already saw how these leaders of rituals disseminated their knowledge to others. However, we also need to consider how these functionaries obtained their knowledge. They probably did so through teachings as a novice and through meetings with fellow priests (Helms 1988). The former is a case of one-to-many transmission. The latter is a case of horizontal or contagious transmission, but as most peers probably insist on the conservation of beliefs and practices it is, in effect, a case of many-to-one transmission. 116 So, the routes of transmission appear to create a highly conservative situation. An individual can induce variation through vertical transmission from elder to child and through horizontal transmission from practitioner to onlookers. However, as most members of the burial community probably insist on a uniform, proper conduct, the conservative many-to-one mode of transmission dominates. These ideas on proper conduct are probably mainly disseminated by a priest to audiences and/or pupils in a one-to-many relation. Although such a relation allows for easy spread of innovations and creation of variation between individuals, innovations are not likely to occur as the religious functionary him- or herself also belongs to a community of priests that is taught by a few individuals and consists of peers that insist the long-term maintenance of set of practices and beliefs. Having established the modes of transmission, let us now take a look at the geographical aspects of communication. Since long it is known that the genesis urnfield phenomenon is not an indigenous development, but that it must have come about under influence of central European cultures. The main region(s) of influence is not exactly known and neither is the route along which the practice and values of the urnfield burial rite spread. It is clear, however, that in general influences come from southern Germany/north-alpine region and the western European urnfield group (Rhine-Swiss-France Group), and that the practice must have spread over the main waterways such as the Rhine and the Meuse (Desittere 1968; De Mulder et al. 2008). Knowing the exact region of origin of the urnfield phenomenon or the route over which it spread need not concern us here, however. What is of interest is how the cultural variants spread from their region of origins to the Southern Netherlands. Two kinds of individuals are probably vital in the spread of the urnfield phenomenon from region to region: priests and (highly influential) political leaders. We already discussed the important role or religious functionaries during burial rites. In the last paragraph it was also noted that amongst the practitioners, high status individuals, such as kin group elders, probably figured most promptly during burial rites and therefore have most opportunity to affect the burial community. I also noted that there probably existed an intimate relation between the political and functional leader; in fact, they might have been the same person or have been part of an institution of dual leadership. What the two have in common is the long distance travels they likely undertook in Bronze Age Europe. Although the geographical extent of these travel are a matter of debate, it is highly probable that not only metal objects covered large distances but that people accompanied them (Kristiansen 1998; Kristiansen & Larsson 2005). Ethnography shows that it are often political and religious leaders that travel long distances either to receive religious 117 training, to exchange items or trade goods, or simply to conquer the unknown. With these travels often comes power and fame for these travelers, the leaders, as space and distance in non-modern societies is often perceived as sacred and supernatural (Helms 1988; 1998). So with these travelling priests and political leaders (or perhaps priestly chiefs) we have the main route through which information on burial rites disseminates on a supra-local level. We can picture now three modes of transmission. Firstly, there are the priests. They obtain their knowledge on the rituals from a supra-local community of religious functionaries in which they have a one-to-many relation with a teacher and a many-to-one with their peers. The priests communicate this knowledge in a one-to-many fashion with audiences of ritual and with pupils in a local community. As both the priest himself, the community of religious functionaries, and the audiences of rituals insist on the maintenance of respected practices, cultural evolution through this route of transmission will in general be very conservative. However, in the case of culture change innovations will probably spread the easiest and geographically furthest through this route, because the priest maintains long distance contacts and a one-to-many relation with the local community. Secondly, there are the political leaders. These are part of the onlooker/practitioner group of the burial community. As onlookers they probably attend more funerals than other members of the local community and attend funerals that are further away. Whereas most members of the local community will probably only attend burials of members of their own community and of nearby communities, political leaders will, because of their contacts through exchanges and travels, will also attend funerals further away. As practitioners they figure more often and more promptly in rituals than other members of the local community and therefore are more likely to influence the onlookers. Even more, because they appear as role models (see paragraph 5.8) However, only the most influential political leaders will probably have a one-to-many relation with the community. The less influential leaders will have a horizontal relation with followers and fellow leaders. In the latter case variation can be high and cultural evolution can be rather rapid. However, like with priests, information will spread the easiest and geographically furthest via the most influential political leaders. However, this route of transmission will likely be conservative when innovations introduced by the political leader are not accepted by the priest. Lastly, there are the members of the burial community that are neither religious nor political leaders. Their geographical span is limited and so is their ability to influence peers as they only figure in the burials of their closest relatives while the insistence of the audience on tradition is likely to be stronger than their predisposition to imitate the individual. These members of the community probably also transmit information through a vertical one-to-one relation, such 118 as a parent-child relation, but in general cultural evolution by this route of transmission is slow (Shennan 2002, 48-51), slower than in horizontal and one-to-many relations. 5.7.2 Means of Transmission Now that we have created a model for the routes of information transmission we will take a look at the media through which this information is spread. We already saw that communication probably mostly took place during ritual or during teaching by a priest or elder. Such ritual communication is of a very distinct nature. Bloch (1974; 1977; 1985; 1986; Bradley 1998, 89) has studied this kind of communication. He found that public rituals communicate through very specialized media. They follow a strict, formalized course with little room for modification. That is why media such as song and dance are used. Texts are usually performed in a prescribed manner, for instance accompanied by certain gestures and uttered in a special manner. By these features the ritual becomes memorised and transmitted between generations with no modification. This accurate preservation is what is most important and archaic forms of language are therefore often used. Bloch explains that the effect of all this is that the contents of the ritual are protected from challenge or evaluation. Through it a distinct conception of time is created, and the basic beliefs expressed through ritual lie outside the passage of time and are therefore not to be challenged (Bradley 1998, 89). So the media used in transmitting information during a ritual bring about conservatism. 5.8 Conclusion In this chapter we set out to get an overview of the cultural, social and ecological context in which the Bronze Age burial rites took place. A description was given of the value system, ecology and subsistence strategies, demography and populations structure, political and religious authority, the routes and means of communication, and the changes occurring in these areas during the period. What we found was that the Bronze Age value system was characterized by conflicting values. For resolving this conflict a system of selective deposition was at place, in which items referring to different, morally conflicting realities were deposited at separate locations in the landscape. Items referring to martiallity and supra-regionality were deposited at unaltered, natural places, while localism and collectivity was stressed during the burial ritual. This sense of collectivity was not something new to be expressed at urnfields, but was probably already a value stressed during the Middle Bronze Age funerary rite as the person as individual did not seem to find much expression in barrow burials. Indications for a growing need to stress this collectivity at the end of the Middle Bronze Age, as suggested by some scholars, are not 119 evidently present, though. There is no evidence for a growing population, a more restricted settlement pattern, nor a closer relation between local communities and elements of the land. Next to collectivity, regularity and traditionalism appear to have been important values for the Bronze Age dweller in his or her dealing with the land. In the Middle Bronze Age B this finds expression in the existence of groups of barrow, fences around settlement terrains, repeatedly used bronze deposition zones and a regular house building tradition. The urnfield as a geographically fixed burial location is in line with such a structured use and conceptualization of the landscape. Indications for major material constraints coming into existence at the end of the Middle Bronze Age are absent. Palynological evidence indicates that the landscape opens up, but evidence for a changing or intensifying agricultural system or a rise in population level is inconclusive. Evidence for changes in the way the population was structured is also absent. The approximate size of communities at different scales was determined. Of most importance was, however, establishing the structure of the burial community, those people that transmit the cultural variants of burial rites. As evidence on this matter is virtually absent, a theoretical model was created, based on ethnographic examples and logic. The Bronze Age burial community probably consisted of three groups: a religious functionary guiding the ritual, a group of people conducting the ritual, and a group of onlookers. The latter two group consists of the same people changing roles between different (stages of) rituals. The group of people conducting the ritual can be divided in two kinds of persons: political leaders (household heads, kin group elders, etc.) and commoners. The type of society existing in the Bronze Age and the nature of the rituals conducted during this period suggest that the religious functionary was a priest. Different routes of transmission were present between the different members of the burial community. The main route of transmission was horizontal transmission: a person watches his or her peers perform at burials and subsequently copies this behaviour when conducting a ritual himor herself. However, amongst these peers not everyone is equally influential. Political leaders will figure more promptly during funerals and attend more funerals than commoners, as they are part of more extensive networks. The priest as an authoritive and charismatic figure will be even more influential, as are the few political leaders of very high status. As per community only one or two of such highly influential figures exist they maintain a one-to-many relation with the audience of rituals, a mode of transmission with the potential of rapid cultural evolution. The priests and political leaders are also the persons who travel furthest and therefore spread information on new burial rites the quickest on a supra-local scale. At the same time there also exists a many-to-one transmission route as the priest and most members of the burial community will likely insist on 120 the maintenance of sacred knowledge and respected practices, thereby sending uniform information to the individual and enhancing conservatism. Equally conservative is the network in which the priest obtains his knowledge. As a novice he and his peers likely obtained information in a one-to-many mode from one or a few teachers. Next to that he has a many-to-one relation with his peers. Also, the specialized media of ritual communication creates a distinct conception of time, evoking that the basic beliefs expressed through ritual lie outside the passage of time and are therefore not to be challenged. 121 122 6. Discussion: Modelling Culture Change 6.1 Introduction In the previous three chapters we have gathered all the building blocks needed to build a model of culture change. In chapter 3 I described the patterns of change in burial rituals from the Middle to the Late Bronze Age. It was shown what changed, when it changed and at what frequency the changes occurred. In chapter 4 we took a look at the ideas and values behind these changing behaviours. Lastly, in chapter 5, we characterized the social and cultural context in which the changes took place. In this chapter I will turn to the main goal of this study: explaining the genesis of urnfields in the southern Netherlands. Now that we know what the cultural constraints, social constraints, mode of transmission, material constraints, and life history of the transmitters are, we can start with formulating a hypothesis to explain the witnessed changes in funerary ritual. This and earlier created hypotheses will be evaluated mathematically, resulting in expected patterns of culture change. These patterns will subsequently be compared with the actual patterns described in chapter 3 to generate a best fit. 6.2 A Darwinian Model of Culture Change The theoretical model to be developed in this paragraph will be a Darwinian model of culture change. In chapter 2 the premises of such a model were discussed. The basic steps of creating such a model were also explained. These are (Richerson & Boyd 2005, 97): -draw up a model of the life history of an individual; -fit an individual-level model of the cultural (and genetic, if relevant) transmission processes to the life history; -decide which cultural (and genetic) variants to consider; -fit an individual-level model of the ecological effects to the life history and to the variants; -scale up by embedding the individual-level processes in a population; and -extend over time by iterating the one-generation model generation after generation. I explained that a model created according these steps consists of several building blocks: a model of life history, cultural constraints, social constraints, material constraints, transmission processes and the population structure of a society. In the last three chapters a description of these 123 building blocks were given. In the following I will consider in an individual-level mode how each of these building blocks might have shaped the process of culture change in single generation. We will start with a model of the life history of the individuals involved in the transmission of cultural variants of burial practices. According to life history theory the schedule and duration of key events in a lifetime of an organism are shaped by natural selection to produce the largest possible number of surviving offspring (Shennan 2002, 102-113). Those individuals that come up with the best allocation of limited resources will be most successful in terms of natural selection. Life history theory is developed in the context of the study of organic evolution. However, in the case of cultural evolution other forces of transformation than natural selection may be at play and the nature of the trade-offs and sources to be allocated may be different. Whereas, for instance, in organic evolution a relevant trade-off is between producing a large litter with little parental investment and a small litter with much parental investment, a trade-off in cultural evolution may be between investing in offspring (private sphere with little influence on peers) and investing in social life (public sphere with much influence on peers). Since information on burial rites is mainly transmitted in the public sphere (see chapter 5.7), the amount of time and energy invested by individuals in obtaining a public role is crucial in the process of the genesis of urnfields. In this regard there exists an important difference between those people carrying the cultural variants of the urnfield phenomenon and those that carry the variants of the Middle Bronze Age barrow burial ritual. As most members of the community were buried in the urnfield period while only a selection of the Middle Bronze Age population was buried in barrows, the urnfield burial ritual took place considerably more often than barrow rituals. In terms of cultural evolution this would mean that when the two variant were present simultaneously, the cultural variant of the urnfield ritual would be transmitted considerably more often than that of the barrow ritual. It is estimated that in the Middle Bronze Age about 15% of the population was buried in barrow (Theunissen 1993, 40), while during the Late Bronze Age almost the entire population was buried in small barrow (see paragraph 5.5). So the chance for people to witness a urnfield burial would be 6 to 7 times greater than the chance to see a barrow burial. And this is without taking into consideration the fact that after 1400 BC barrows were only rarely constructed (Bourgeois & Arnoldussen 2006). This means that in a situation in which there were no cultural, material or structural constraints and information on the two variants was transmitted in similar ways and in a similar population - a neutral situation - the urnfield phenomenon would automatically become the dominant funerary rite. So in terms of natural 124 Fig. 6. 1 Assumed life cycle of transmission selection, holding the cultural variant of the urnfield ritual significantly increases ones cultural fitness. Secondly, let us consider how the transmission processes might have shaped the genesis of the urnfield burial ritual on an individual level. In the last chapter a theoretical model was created of the modes of transmission current in Middle and Late Bronze Age southern Netherlands. Three kinds of individuals were involved in the transfer of ideas on burial practices: commoners, political leaders and priests. The commoners spread variants through horizontal transmission at rituals and through vertical transmission in parent-child relations. The political leaders spread information in a similar manner, with the difference that they are more salient than others as they 125 figure more promptly and more often at funerals. They are also more influential because of their authority and personal charisma. As a religious authority the priest is even more salient and influential, spreading variants during rituals and perhaps as a teacher to pupils. At the same time a conservative many-to-one mode of transmission is at place in society, as the priest and most members of society insist on the maintenance of traditional practices and beliefs. A summary of the individual-level model of transmission modes is given in figure 6.1. This is, of course, a very general model and changes in peculiarities of the system from the Middle to the Late Bronze Age cannot be inferred from the archaeological record. We do know, however, that there were changes in the northwest European networks. Throughout the Middle Bronze Age and the Late Bronze there is an increase in the number of imported an deposited bronzes in the southern Netherlands (Fontijn 2002, 213-5). Apparently the exchange network had opened up to a greater number of people (cf. Fokkens 1997). As it were the political and religious leaders that maintained long-distance contacts (with other priests and leaders) they were the ones involved in the transmission of information on a supra-local level (Kristiansen & Larsson 2005). These are also the individuals that have a one-to-many relation with the local community. When innovations are accepted by a local community, for instance during a period of social change or turbulence, variants spread fast through one-to-many relations. Faster than through the vertical and horizontal relations existing amongst commoners and less influential political leaders. So the routes of transmission are so constellated that - all things being equal new, exotic variants spread by priests and high status political leaders will out compete the existing variants spread by commoners and less influential leaders. And as more and more people entered the supra-local contact networks towards the Late Bronze Age the frequency of exotic variants entering local populations will have been even higher. So it appears that, like the life history of the transmitters, the existing transmission processes would, all things being equal, promote the variant of the urnfield ritual over the barrow ritual. That is, when this new variant is transmitted by highly influential priests and political leaders as would be the case with exotic practices and beliefs. And I believe it is fair to assume that the elements that make up the urnfield phenomenon are exotic variants. In chapter 3 we noted that the burial rite changed in several ways from the Middle to the Late Bronze Age (table 3.12). Most elements of the Late Bronze Age rite were already present in the Middle Bronze Age, such as the cremation rite, barrow groups, ring ditches, urn burials, etc, but they occurred far more often or even came to dominate in the urnfield rite. Also some new elements appeared such as an elaborate repertoire of pottery types. These changes, however, do 126 not seem to be gradual ones. It appears that they occurred rather sudden somewhere during the Ha A period (see chapter 3) and had completed almost instantly: there are no indication that the proportion of barrows with surrounding ditches increased throughout the Middle Bronze Age and there are no urnfields where some barrows still have surrounding features other than ditches; neither are there indications for the proportion of burials in small pits increasing throughout the Middle Bronze Age and there are no urnfields where some barrows still have burials structures other than small pits; there is no apparent gradual decrease in barrow size during the Middle Bronze Age and barrows with a diameter over 10 m (the average size of Middle Bronze Age barrows) are extremely rare at urnfields; after a period in which almost no barrows were constructed there is a sudden increase in the amount of barrows constructed; barrow groups are known from the Middle Bronze Age but these are still significantly smaller than the average urnfield and there are no known examples of barrow groups that are continuously used from the Middle Bronze Age to the Late Bronze Age (Gerritsen 2001, 152-7); there is no apparent typological continuity between Middle and Late Bronze Age pottery types and there are no Middle Bronze Age examples of pottery being used other than as urn; there is no gradual increase in the number of burials with metals throughout the Middle Bronze Age. Only the rite of cremation may have gradually increased in frequency throughout the Bronze Age, but this cannot be ascertained (see paragraph 3.4). In the northern Netherlands there is an upsurge in inhumation burials in the north-eastern Netherlands, though (Lohof 1994). Long barrows appeared for the first time already before Ha A, but appear to have diversified suddenly during this period. So, apparently most elements of the Late Bronze Age burial rite did not gradually change throughout the Middle Bronze Age or even the Ha A period. What is more, the characteristics of urnfields always occur together, never in isolation. For instance, there are no examples of isolated Middle Bronze Age type barrows containing burials with urnfield pottery. Nor are there urnfields consisting mainly of barrows with post circles or of large barrows. It seems that the elements came about as a package. Just as one would expect if the burial rite would be an exotic phenomenon. Was the burial rite to be a local development, one would expect an experimental phase in which the elements changed gradually and occurred in differing compositions in different communities. Rather the elements entered the southern Netherlands fully developed and as a package, probably introduced from regions Rhine upwards where the same elements appeared earlier and did developed gradually (Ruppel 1990; Desittere 1968; Müller-Karpe 1959). Thus far we have established that the urnfield ritual consisted of a set of exotic variants and that such exotic variants were to be promoted over the existing, local variants due to the life history of 127 the carriers and the modes of transmission. Let us now look at the socio-cultural and ecological effects on the individual-model. Were there any cultural or material constraints on the spread of the phenomenon in our region? In chapter 4 and 5 an overview was given of the values and beliefs expressed during the urnfield ritual and of the nature of the value-system at large. We found that the value system of the Bronze Age in the southern Netherlands was riddled with conflict, as becomes clear from the system of selective deposition of bronzes. Values as martiality and belonging to a supra-regional community were physically and ideologically kept apart from values like collectivity and localism, by depositing the bronzes that expressed these values at different places. Exotic items and weaponry were deposited at natural places. The sense of collectivity and localism found expression at urnfields, where almost the entire community was buried in an uniform manner with only local items. For Middle Bronze Age barrows it had long been assumed that the burial rite was less egalitarian. The barrows were supposed to be 'family barrows' built near farm houses and used for the burial of the there residing family head and his (male) relatives (Fokkens 2003). However, it has been shown that the idea of a family barrow for the head of a family is hard to maintain as barrows were only rarely erected near a farm house and most of the time contain to few interments to be the burial ground of a family (Bourgeois & Fontijn 2008). Neither do sex, age or status appear to have been criteria for the selection of individuals for primary or secondary burial (see paragraph 5.3). In both primary and secondary burials individuals of all sexes and age groups can be found without any obvious indication of social status - apparently a representation of a community. So like the urnfield, the barrow seems to be a representation of the collective, albeit a symbolic one. The conceptual and spatial relation between a community and the burial ground is, however, less clear for barrows than for urnfields. As urnfields are fixed burial grounds that contain the deceased of a group of people the size of a local community, it is general assumed that the urnfield symbolizes this local community and is located as a marker on the territory of the community (Gerritsen 2001). For Middle Bronze Age barrows it is unknown to which kind of communities they belonged and how they spatially related to the locality of communities. What is clear, is that through time barrows were increasingly more often erected near older barrows, so apparently the presence of older barrows were important in the location of new barrows (Fontijn & Bourgeois 2008). This is in line with the general attitude Middle Bronze Age B people towards the land. The repeated use of the same unaltered places for bronze deposition, the building of new barrows 128 near old ones, the increasing reuse of these barrows for secondary burials, the traditionality and regularity in house building, and the fencing of the area around farmyards indicate that the interaction with the Middle Bronze Age B landscape was characterized by regularity, traditionality and structuring. So like that of the urnfield barrow, the placement of the Middle Bronze Age barrow was more preset than often thought. In earlier models the genesis of urnfields is often explained as the result of a cultural preference for the new ritual, because of a growing need to express individuality (Fokkens 1997) or collectivity (Gerritsen 2001). In paragraph 5.3 it was explained that there are no indications for either a growing sense of individuality or collectivity during the Middle Bronze Age. Rather it appears that there were no significant changes in either the value-system or the beliefs behind the different rituals: there were no cultural constraints on excepting the urnfield phenomenon. Already in the Middle Bronze Age B burial grounds were part of a structured landscape and were a symbolic representation of a community. The new burial rite arriving at the start of the Late Bronze Age was completely in line with the already existing practices and believes: they were spatially fixed burial places that functioned as symbol of a local community. And most of the practices, such as the building of barrows, digging of ring ditches and cremating the deceased were already well-known. So, although specific notions may have changed from the Middle Bronze Age to the Late Bronze Age, such as the kind of community represented by the burial ground, the general beliefs of barrow cemeteries being the burial ground of a community in specific part of the structured landscape remained unchanged. It is therefore that the new variants could be easily excepted, even though rituals are in general conservative. It is not only the value system, however, that can encourage or discourage change. People do not change or maintain beliefs and behaviour at random, but on the basis of expected or perceived consequences of behaviour in a particular natural environment. These environments are unstable and thus provide the external stimuli for change. In chapter 5 it was explained, however, that there are no apparent changes occurring in the material and ecological conditions from the Middle to the Late Bronze Age. It is therefore unlikely that material constraints have influenced the evolution of the burial rite. By now we have drawn up an individual-level model of the process of culture change in which life history and social constraints are the main forces of change, while cultural and material constraints are deemed unimprtant. On the basis of the assessment of the nature of the cultural variants under consideration and of the socio-cultural context I made several assumptions, which I will now make explicit: 129 As the elements that make up the urnfield phenomenon do not appear to have evolved gradually and always appear together as a package, we can consider this phenomenon a qualitative rather than a quantitative variant. Meaning that it is a state rather than a position on a continuum (Richerson & Boyd 1985, 75-6). As the urnfield phenomenon is practiced considerably more often than the barrow ritual, the cultural fitness of the former is considerably higher than that of the latter when the variant is displayed by transmitters with equal weight. Variants of burial rites are mainly acquired through vertical and/or oblique transmission in pre-adult life and through horizontal transmission in horizontal life. Amongst peers, political leaders (of an undefined nature) and religious functionaries (in the form of priests) have more weight than other people, because of personal charisma and authorative position. This is a first social constraint. Political leaders and religious functionaries are more salient as they figure more often and more prominently at funerals, resulting in a non-random selection of cultural parents. This is a second social constraint. As the changes in burial rite were abrupt rather than gradual the urnfield phenomenon is an exotic variant coming from areas Rhine upwards, where burial practices developed earlier and gradual. The exotic variant is introduced in local communities of the southern Netherlands by political leaders and religious functionaries. As there is no conclusive evidence for significant changes in either value-system, material conditions or the values and beliefs expressed in the burial ritual from the Middle Bronze Age B to Late Bronze Age, a content-based (or direct) bias on the basis of primary or secondary values did not occur. Neither did cultural constraints exist. In the case of institutional rituals, priests and most members of society will insist on the maintenance of respected beliefs and practices. This conservatism is reinforced by the nature of the media employed in rituals. A situation of social change or turbulence therefore needs to be assumed for a change in rituals to take place. In the case of the changes in burial rite under study these social changes need not have been disruptive and indeed there are no indications for disruptive social change - as the changes were mainly transformations of practices rather than belief. The population structure is characterized by a dynamic whole of overlapping and shifting communities of different nature. This means that the burial community in broadest sense (the buried and the mourners) does not overlap with the local community. The social 130 structure therefore allows cultural variants to spread gradually through the entire community, and not from pocket (Kulturkammer) to pocket. We are now ready to implement this individual-level model in a population and scale it up over time. However, before we do this I first want to discuss several alternative models. 6.3 Alternative Models In the previous chapters the earlier models of the genesis of urnfields formulated by Fokkens (1997), Roymans and Kortlang (1999) and Gerritsen (2001) were discussed at several occasions. It has been shown that these models are not valid, as new evidence proves assumptions on social and ecological context untenable (chapter 1.2 & 5.4). Nonetheless, it is interesting to test the theoretical plausibility of the models. In order to do this we must first reformulate them in Darwinian terms. The models can be subdivided in two types. Content-based bias models The first group of models contains those that explain cultural evolution mainly as the result of content-based (or direct) bias. These are the models of Fokkens (1997) and Gerritsen (2001). According to them the selection of ideas and beliefs was based on the cultural values individuals held. Fokkens suggested that the genesis of the urnfields was a logical outcome of a process of individualisation that must have started at the end of the Middle Bronze Age, as indicated by evidence on settlements, bronze exchange and burial ritual. To formulate this in evolutionary terms, there existed a preference based on secondary values for variants that stress the importance of the individual. Gerritsen, on the other hand, suggests a preference for variants that express the importance of the community, as there was a growing need to express collectivity. In both models, ideas or assumptions on life history, modes of transmission, social constraints and population structure are not made explicit. Group selection models Roymans and Kortlang (1999, 36-42) have put forward the hypothesis that changes witnessed in burial rites are the result of the way society coped with problems resulting from continued demographic expansion and growing pressure on land. In a period in which the control over land, rather than over labour, was vital to the reproduction of local domestic groups, urnfields functioned as territorial markers. In this model the human behaviour is explained in terms of group-level function. It is a functionalist argument that explains the existence of the burial rite by 131 showing that it contributes to the welfare of the group. Like most functionalists, Kortlang and Roymans do no explain the mechanisms for generating and maintaining the adaptation, but phrases like 'the reproduction of the local group' (Roymans & Kortlang, 1999, 40) suggest that as in most functional explanations - cultural group selection is considered the main mechanism. The general reasoning is that groups that do not posses the functional behaviour become extinct, leaving the groups that do posses the behaviour as survivors. 6.4 Testing Models We now have three types of models for culture change: a model in which natural selection and social constraints are the main force of cultural evolution; models in which content-based bias is the main force of change; and the group-selectionist or functionalist models. Up till now the presumed processes that led to the genesis of urnfields have been worked out intuitively and verbally. To see whether any of these models have validity we need to formulate them mathematically, so that we can see what the effects of the assumed forces of evolution are when they are embedded in a population and extended over multiple generations. The patterns resulting from these models can then be compared to the patterns observed in the archaeological record of the southern Netherlands. These patterns were described in chapter 3. I explained there that due to the rather coarse chronological resolution it is impossible to determine the frequency of cultural variants for a period shorter than 150-200 years. It was established, though, that the cultural variant that is the urnfield phenomenon came to dominate during Ha A, that is in a period of 200 years. So what we need is a model of cultural evolution that allows for culture change to happen in such a short period. Let us start with examining the theoretical probability of the group-selectionist model of Roymans and Kortlang. In chapter 2 it was explained that group adaptation is not in line with the methodological individualism maintained by evolutionary biologists, i.e. the view that largerscale entities merge from interactions between individuals (Shennan 2002, 212). Evolutionary biologists explain that humans are self-interested organisms that should adopt only beneficial behaviour and beliefs, and that those individuals that do not so would loose out to individuals who prioritize their own reproductive success. Group selection can counteract this process only when groups are very small and migration among group is very limited. Also, group extinction does not occur often enough for group selection to eliminate deleterious practices (Shennan 2002, 28-9; Soltis et al. 2005, 204-6). 132 Cultural variation can, however, be more prone to group selection than genetic variation. Group selection can be an important force when differences among groups are maintained. Such different equilibria can be obtained through biased transmission, for instance when it has advantages for the individual to obtain the common-type variant (for example, in the case of punishment-enforced norms) or when individuals prefer to adopt the most common variant (conformist bias). In these cases strong individual-level forces maintain differences among groups, even when groups are very large. And unlike many genetic models, this form of group selection does not need the extinction of groups by members dying, but only that members disperse throughout the metapopulation (Soltis et al. 206-7). Mathematical models analyzed by Boyd & Richerson (1985, chapter 7 & 8) show that group selection will indeed work when certain criteria are met. So it appears that theoretically the model of Roymans and Kortlang does have merits in the case of cultural evolution. What we need to know is the timeframe in which group selection can give rise to a phenomenon like the urnfield burial rite. Soltis et al. (2005) have used empirical, ethnographic data from Papua New Guinea and Irian Jaya to underpin the assumptions of the group selectionist model. They explored the rate of group extinction, the manner of group formation, and the effect of persistent cultural differences on group growth and survival. The empirical data allowed them to estimate an upper bound on the rate of adaptation that could result from group selection. They found that extinction rates per generation of the studied groups ranged between 2 and 31 percent, which allowed them to calculate the rate (or time) of culture change, t, for different initial and final fractions of the favourable trait and different extinction rate, using (1.1) where e is the fraction of groups in which the deleterious variant is common and q is the fraction of groups where the advantageous trait is common (Soltis et al. 2005, appendix A). This showed that group selection is unlikely to lead to significant culture change in less than 500 to 1000 years. More often it would have taken significantly longer (Soltis et al. 2005, 218-221). A timeframe which considerably exceeds that in which the urnfield phenomenon came to be the most common burial practice in the southern Netherlands. It has to be noted, however, 133 that this is just one model of group selection - competition among small, heterogeneous groups. But this type seems to be most likely for the Dutch Bronze Age groups, compared to a situation of, for instance, an encroaching cultural frontier (Soltis et al. 2005, 221). So I think it is safe to say that the model of Roymans and Kortlang is untenable on both empirical - there is no evidence for population pressure or significant territorial reorganisation at the start of the Late Bronze Age (chapter 5.3) - and theoretical grounds. The second group of models to be tested theoretically are those in which the main force of cultural evolution is a direct bias; the models by Fokkens and Gerritsen. Although each scholar defined the preference trait - the criteria by which the value of the variant under consideration is determined by an individual - differently, the mathematical model for both models can be similar as long as the urnfield phenomenon is the preferred trait. Such a model has been analyzed by Richerson and Boyd (1985, 137-41) for the linear evolution of qualitative variants. In this model for the distribution of a behavioural trait within a population the trait can take on two states, c or d, of which c is the preferred trait (in our case the urnfield phenomenon). We only want to assess the force of direct bias, so we suppose that all cultural parents have equal weight (there are no social constraints). This is a simple case in which the effect of a direct bias can be shown as follows (2.1) in which p and p' are the frequency of the preferred variant before and after transmission respectively and B is the strength of the bias (Boyd & Richerson 1985, 138). This model shows that each generation the bias moves the frequency of the variant in a population by an increment, Bp(1 - p), from the initial frequency. So directly biased transmission creates a force that increases the frequency of the culturally preferred variant. It is important to note, however, that the increment that needs to be moved from the initial value by the bias, p(1 p), is the (binomial) variance for populations that consist of dichotomous characters. This means that the magnitude of the force depends not only on the strength of the bias, but also on the variance of the character in the population. In other words, if one variant is very common, the direct bias would have little effect as most sets of parents would contain the same variant, while the offspring needs to be exposed to different variants in order to express its preference. Statistically put, this means that when the frequency of a trait approaches zero (or one), the 134 increment to be moved by the variant, p(1 - p), approaches zero (Boyd & Richerson 1985, 138; Bettinger 1991, 189). Of course, this has implications for the validity of the models developed by Gerritsen and Fokkens. In the case of a low initial frequency and/or a weak bias it takes several tens of generations for a variant to increase to a high frequency (fig. 6.2). In chapter 3 we saw that the urnfield phenomenon rose to a high frequency during Ha A in less than 200 years or about 10 generations. For this to happen when direct bias is the only force of change, either the bias has to be very strong and/or the initial frequency has to be high. Neither Fokkens nor Gerritsen specify these conditions. In chapter 5 I showed that there is no empirical evidence for either a growing sense of individualism or collectivism at the end of the Middle Bronze Age and the Late Bronze Age. Such evidence is only apparent for the Early Iron Age. This means that if the preferences existed during earlier periods, they were likely to be still developing and therefore did not yet provide a strong bias. A rather high initial influx is therefore needed in order to arrive at a large frequency of the urnfield variant in less than 10 generations. So a direct bias alone is not enough to explain the genesis of urnfields. Fig. 6. 2 Time path of the frequency of a cultural variant favoured by directly biased transmission. The initial frequency of the favoured variant is 0.1 and the bias parameter, B¸ is also 0.1. (Richerson & Boyd, fig. 5.1). 135 So this leaves us with the last model, in which natural selection and social constraints are the main forces of cultural evolution. Earlier I developed an individual-level model of cultural transmission for the variants of funerary rites, based on several assumptions on the nature of the variants under consideration and the context in which they were transmitted. I will now embed this model in a population and see what effects on the frequency of the variants are over several generations. I will start by discussing the effects of the social constraints. To do this I will start by giving a simple 'recursion' - a rule that allows us to predict the frequency of a variant, q, in the next generation, given the value of q in this generation - for haploid sexual organisms. In the case of genetic transmission by haploid organism there are sets of two parents, each parent has the same weight (1/2), and there are two variants (alleles). We denote the frequency of variant a after transmission q'. For large populations (where cultural drift has no effect) the following recursion can be formulated (Boyd & Richerson 1985, 62) (3.1) when mating occurs at random this becomes (Boyd & Richerson 1985, 62) (3.2) and after some algebra (3.3) q' = q In the case of cultural transmission there are of course in most cases more than two parents and the weight of these cultural parents might differ, for instance, because of the social role of the 136 parent. Equation 3.1 can easily be adjusted to allow for this. For instance in the case of linear transmission by three randomly selected cultural parents with a distinct weight, Ai, and two variants, c and d, the formula for the frequency of c after transmission, p', becomes (Richerson & Boyd 1985, 65) (3.4) In this formula the probability that a set of models with ccd is formed is labelled Prob(ccd) and so on. The equation says that the probability that a randomly chosen individual in the population of naive individuals holds variant c is equal to the product of probability that a particular cultural "mating" results in c (for example, A1 + A2) and the probability that that particular mating occurs (for example, Prob(ccd), summed over all possible matings. The probability of each set of cultural parents with I (I = 0, ... , 3) models with variant c and 3 - I models with variant d is pI(1 p)3 - I. To evaluate equation 3.4 the probability distribution of the sets of models needs to specified. This results in (Boyd & Richerson 1985, 65) (3.5) and as A1 + A2 + A3 = 1, this can be simplified to (3.6) or (3.7) p' = p 137 By using algebra these recursions can be formulated economical for sets consisting of n number of models as (3.8) where (3.9) This equation defines the probability that a naive individual acquires cultural variant c given that the n cultural parents form the particular set of values X1, ..., Xn. Here Xi is the numerical value (for instance, c=1 and d=0) of the cultural variant of the ith model, in a particular set of models. The importance of the ith parent in the transmission is defined as Ai. For all varieties of n, that is for sets of models of all sizes, it can be shown that transmission leaves the frequency of the different variants unchanged, as long as the models are randomly selected and transmission is linear (Boyd & Richerson 1985, 67, box 3.1) - no matter the weight of the different models. This is counter to the intuitively expected effects of social constraints mentioned in the previous paragraphs, but only at first sight. It was expected that the variants held by political leaders and priests would grow in frequency because: 1. these models have more weight (it was explained that their personal charisma and authority makes them more influential); 2. the models are more salient (it was explained that they perform more prominently and more often at funerals). And these expected effects will indeed occur as long as the sets of models are not formed at random, or "nonselectively" - and this was the case in the southern Netherlands in the Bronze Age. First of all, the probability that the ith model has cultural variant Xi, defined as Mi(xi), was different for the Bronze Age population than in the evaluation of equation 3.8. In the evaluation Mi(xi) had the following property: (3.10) Mi(1) = p Mi(0) = 1 - p 138 saying that the frequency of c amongst each of the models is the same as the frequency of c in the population as a whole. This leads to the frequency of the variant being unchanged after transmission. However, as some individuals are more salient than others in the Bronze Age population they have a bigger chance of being selected as a model, with the result that the selection of models is no longer random: the chance that a model with variant c is selected, u, is larger than the frequency of the variant in the population, p. The property of Mi(xi) then becomes (3.11) Mi(1) = u Mi(0) = 1 - u with the result that frequency of the variant after transmission is now (3.12) p' = u This means that the higher salience of priests and political leaders can lead to higher frequency of a variant if the frequency of the variant in the population of salient models, p*, is characterized as p* > 1 - p* and the weight of all models is kept equal (the inclusion of an individual in the set of models does not depend on the social role of the individual). Secondly, equation 3.10 does not hold when the frequency of a variant in a population of individuals with a certain social role differs from the frequency of the variant in the metapopulation and the weight of the models with different roles differs. Something which we could expect for the Bronze Age when the most influential models, the priest and travelling political leaders, adopt exotic variants from a supra-regional community of priests and political leaders. In this case, the probability that an influential model has cultural variant Xi does not depend on the frequency of Xi in the meta-population of possible models, but the frequency of the variant in the population of influential individuals, p*. This has the result that the weight of the models now does influence the frequency of the variant after transmission, meaning that the frequency of the variant can increase when p* > 1 - p* and the weight of the social role is high enough. We can illustrate this by considering a case of two cultural parents with different social roles, for instance a parent and a teacher, and a dichotomous cultural trait with two variants, again 139 c and d. The frequency of c after transmission in the next generation, p", would be (Boyd & Richerson 1985, 184) (3.13) where p* is the frequency of a variant in a population of teachers and p' is the frequency of a variant in a population of parents. Equation 3.13 can be evaluated as (Boyd & Richerson 1985, 184) (3.14) where A is the weight of parents. This equation can be simplified to (Boyd & Richerson 1985, 184) (3.15) This equation says that the frequency of the cultural variant c after transmission is the weighted average of the frequencies of c among parents and teachers, where the weights are the relative importances of parents and teachers in the transmission of the cultural trait under consideration (Boyd & Richerson 1985, 184). It has to be noted that in equation 3.13 the presence of a model with social role a is a given. In contrast to what was said earlier, this means that the salience of individuals does not have any effect on the probability that a model with variant c is selected, as the probability depends only on p* or p'. However, the situation of equation 3.13 is probably to stylized (cf. 140 Richerson & Boyd 1985, 186). When acquiring a variant of burial rites during the Bronze Age different naive individuals will have been exposed to different numbers and kinds of cultural parents. To allow for this in the model, we must assume that a given naive individual is only exposed to a subset τj of all possible roles (Richerson & Boyd 1985, 186-9), with Prob(τj) being the probability that a naive individual is exposed to subset τj. This probability depends, amongst other things, on the salience of the individuals holding a certain social role. So in reality salience of the models did have influence. So mathematically it can be shown that social constraints in the form of the salience and influence (weight) of models with a certain social role can result in a higher frequency of a variant after transmission, if the weight of the models is high (enough) and the frequency of the variant in the population of models, p* is characterized as p* > 1 - p*. But are these requirements met? In chapter 5 a theoretical models was created in which the influential models in the Middle and Late Bronze Age were the priests and the travelling political leaders. It was assumed that the weight of these models was high - probably high enough to increase the frequency of a cultural variant. The second condition, p* > 1 - p*, requires that there was a readiness amongst political leaders and priests to adopt variants coming from central Europe - most of them should adopt the urnfield variant when they were exposed to it in supra-local community of priests and political leaders. Why would this be? Unfortunately, I am not able to give a conclusive answer on this question. A few suggestions can be given, though. Roymans (1991) has suggested that the exchange networks of which the political leaders of the southern Netherlands were part can be characterized as a prestige good economy. In such an economy the control over prestigious items and knowledge of rituals is politically significant to establish and maintain power by elites. The elites of the southern Netherlands will in such a network maintain a core-periphery relationship with the elites residing in the upper Rhine areas and bring in exotic items and knowledge out of socio-political necessity. Although this is a possible explanation, there are several problems with it. First of all, as I explained in paragraph 5.6, the exact nature and basis for authority in the southern Netherlands is unknown. Although it is most probable that it were political leaders who were involved in the exchange of items and knowledge, it is by no means certain that the exchanged prestige goods and knowledge were the basis of their authority. Secondly, the prestigious nature of these exotic items and knowledge is assumed, while in reality their ideological and social weight might be circumscribed (see paragraph 5.3.3). Another reason for the rapid adoption of exotic variants by priest and leaders could be higher population densities Rhine upwards. In such a situation a unidirectional spread would be 141 caused by a statistical effect of influential models residing down the Rhine receiving information more often from models living in the upper parts of the Rhine than the other way around. If by each transmission the chance of accepting the variants is similar, than the chance of people not accepting a new variant would be smallest down the Rhine. Another possibility is that the higher population densities motivated pioneers or that the larger communities compelled the smaller ones in adopting practices through pressure or sway. Such a crucial role for demographic differences has been proposed for the expansion of the Rhine-Suisse-France Group (Brun 1984; 1988). However, to see whether this was also the case in the spread of the urnfield phenomenon to the southern Netherlands a detailed knowledge of the demographics of the Rhineland communities needs to be created. Something which is outside the scope of this study. In conclusion, it can be stated that for a high salience of priests and political leaders to be a force of change during the Bronze Age we must assume that: 1. amongst priests and political leaders the urnfield variant is readily adopted, leading quickly to p* > 1 - p*. For high influence to be a force of change we must also assume that: 2. priests and political leaders have a high enough weight. On theoretical grounds assumption 2 appears plausible (see chapter 5). A validation of the first assumption is not possible within the bounds of this study, but is certainly not impossible given the proper socio-cultural dynamics on a supra-regional scale and a sufficiently high value for p*. If these requirements are met social constraints can be a force of change that is strong enough to allow for the full adoption of a new burial rite within a period of 200 years, if the salience and weight of the priests and political leaders is high enough. Social constraints were, however, not the only possible force of change highlighted in the individual-level model. It was suspected that the life history of the carriers of the urnfield variant might give the carriers a selective advantage, as the urnfield rite was executed 6 to 7 times more often than the barrow rite. We can evaluate this mathematically by adding an episode of natural selection to the simple recursions of linear transmission defined earlier. These recursions showed that 'p = p when models are randomly selected. Now if we suppose that individuals characterized by different cultural variants differ in the probability that they become cultural parents, we can define the probability that an individual with variant c becomes a cultural parent Wc and that for individuals with variant d Wd. To arrive at the frequency of variant c during one generation, p", as a function of the frequency of c among parents of the previous generation, p, we can use the simple formula (Boyd & Richerson 1985, 182) (4.1) 142 This recursion tells us that the change in frequency of c over one generation, ∆p = p" - p, is positive for all values of p when Wc/Wd > 1. Meaning that the cultural variant with the highest cultural fitness increases. It must also be noted that ∆p is largest for p = 0,5 and approaches zero as p approaches zero or one.3 So like with equation 2.1 of direct bias, the strength of the force depends on the variability in the population. However, this dependency is not as strong as for the direct bias - as the probability for carriers of the urnfield variant to become cultural parents is 6-7 times as high as for the carriers of the barrow variant, the frequency of the urnfield variant can become dominant in just a few generations, all other things being equal. With such a process we have a situation of high initial influx needed for social constraints (or direct bias) to be a significant force of culture change. With the effects of natural selection and social constraints combined we have a model that can explain the genesis of the urnfield phenomenon within 200 years. 6.5 Conclusion In this chapter we have created a model to explain the increasing frequency at the end of the Middle Bronze Age of the cultural variant that is the urnfield phenomenon. On the basis of the assessment of the socio-cultural context in the previous chapter an individual-level model was created in which life history and social constraints were posed as the main forces of culture change. Cultural and material constraints were deemed unimportant as there are no indications for significant changes in value system or ecological conditions respectively. Cultural constraints in the form of a direct bias or preference for the urnfield phenomenon were the main force of culture change in earlier models created by Fokkens (1997) and Gerritsen (2001). In a model created by Roymans and Kortlang (1999) changes in material conditions led to group selection processes in which urnfields were beneficial to groups as territorial markers. These tree types of models were evaluated by embedding the supposed forces of change mathematically in a population and extend them over multiple generations. The results of the mathematical models could be used to validate the intuitively expected outcomes of the different models. For the models to be valid the supposed forces of change would have been able to increase the frequency of the urnfield variant to a near maximum level in less than 200 years - the pattern established in chapter 3. It was shown that if the main force was 3 This recursion can be modified to analyze the effects of holding a variant that changes the probability of obtaining a certain social role in a set of n models (Boyd & Richerson 1985, 182-9). Here it is assumed, however, that holding either the urnfield or the barrow variant does not changes ones chances for obtaining a social role. 143 group selection as the result of competition amongst small, culturally heterogeneous groups, it would have taken at least 500 to 1000 years for the urnfield phenomenon to become dominant. A direct bias in the form of a cultural preference could increase the frequency of the urnfield variant in less than 10 generations, but only if the initial frequency of the variant is high enough. So group selection and cultural preference alone are not enough to explain the rise of the urnfield phenomenon. In chapter 3 a theoretical model of the modes of transmission was created. This model showed that social constraints existed in the form of priests and (far-travelling) political leaders being more salient and influential. It was shown through several mathematical models that such constraints can indeed lead to significant cultural change in less than 200 years, if the initial frequency of the urnfield variant in the population of influential individuals is higher than the frequency of the barrow variant and if the weight of these individuals is high enough. On theoretical grounds it is likely that the latter requirement was met in the Bronze Age. Conclusive empirical or theoretical evidence to suspect that the former requirement was met is lacking, however. There is one force of change, though, that could create such a high initial influx: the selective advantage of holding the urnfield phenomenon. As almost the entire community was buried in an urnfield, while only a small selection was buried in a barrow, the urnfield ritual took place significantly more often than the barrow ritual - 6 to 7 times as often. This means that the carriers of the urnfield variant are significantly more likely to become a cultural parent than the carriers of the barrow variant. This allows natural selection on cultural variants to be such a potent force that the urnfield phenomenon can become dominant in just a few generations. Combined with the effect of the social constraints (and perhaps a direct bias) this allows the genesis of the urnfield phenomenon to take place in a period as short as the Ha A. 144 7. Concluding Remarks: The Genesis of Urnfields 7.1 Introduction This study set out with noting several problems with current explanations of the spread of the urnfield phenomenon throughout Europe. Usually the changes in burial rituals taking place in the Late Bronze Age are characterised as a marked reorientation in spiritual life in large parts of Europe, where urnfields are thought to represent a new era of “cultural homogeneity” and “uniformity of beliefs” across the continent. Indications that in several regions the changes in burial rites were gradual and that the practices and beliefs of the funerary rituals differed between places was reason, however, to reconsider current explanations of the genesis of urnfields. The southern Netherlands was chosen as a case-study, because of the availability of many excavated urnfields and 14C dates in this region and because the socio-cultural context is well-studied. Several models of the genesis of urnfields were already created for the southern Netherlands. There are, however, several practical and theoretical problems with these models, such as a poor understanding of the material culture, traditions and beliefs of the Middle Bronze Age B and Late Bronze Age and the focus on only a single element or aspect of the burial rite. The main theoretical problem is the inability to get from short-term, individual-centred scenarios to long-term, structural changes. To overcome this problem a different theoretical framework was adopted in which long-term processes can be analyzed by using Darwinian, mathematical models of culture change. Three research questions needed to be answered to find out when, how and, most importantly, why the urnfield phenomenon was adopted in the Southern Netherlands. The first question concerned when, where and in what form the elements of the urnfield phenomenon were introduced in the Southern Netherlands. An inventory was made of graves from the Middle Bronze Age B and Late Bronze Age. On the basis of this inventory a description was given in chapter 3 of the material culture and traditions of these two periods. Contrary to what was done in earlier models, changes in all aspects of the burial ritual were considered: burial monuments, burial practices, ceramics and metals. It was found that, except for new pottery types, all elements of the urnfield rite were already present in the Middle Bronze Age. Nonetheless, twelve changes were noted in the frequency and dimensions of these elements (table 3.12). An important finding is that these changes were rather abrupt, contrary to what is generally thought. There is no gradual change from the dimensions and frequencies characteristic for the Middle Bronze Age barrow ritual to those characteristic for the Late Bronze Age urnfield ritual. For instance, there is no gradual increase in the number of barrows with ring ditches or a gradual 145 decrease in the size of barrows. Also, there are no examples of urnfields that contain elements in both Middle Bronze Age and Late Bronze Age frequencies and dimensions. For instance, there are no Late Bronze Age urnfields that contain both barrows with post circles and ring ditches. So it appears that the changes in burial rites were instant and came about as a package, probably introduced from areas Rhine upwards. As the first examples of urnfield burials date to the beginning of Ha A and the last convincing examples of typical Middle Bronze Age barrow burials date to the end of Ha A, the urnfield phenomenon must have become dominant in less than 200 years. The second question concerned the ideas and beliefs behind the different elements of the urnfield phenomenon. In chapter 4 the kinds of personal and communal identities expressed at the burial grounds were examined. To see how personal identities were constituted the meaning of grave goods was traced by reconstructing the biography of the items. Fontijn (2002) had previously noted that the simple metals from urnfields display a local identity. Pottery seem to express similar values. Although pots vary in quality and type, a very few even being of a distinct supra-regional style, people were generally interred in or with vessels of a local style, signalling no apparent major distinctions in social role or status - differences are expressed in a local, egalitarian idiom. Similar concerns become apparent in the lay-out and monument forms of urnfields. Two types of barrows were constructed at the burial grounds: long barrows and round barrows of different sizes. It does not appear that the kind of objects deposited in the two kind of monuments are different, given no indication for major differences in the kinds of person being buried in them. This concurs with the uniformity in the lay-out of urnfields: within an urnfield most monuments are of similar dimensions, have a similar orientation and are part of a continuous conglomerate. So, like the personal identities, the external appearance of urnfields appears to be characterized by similarity and equality. The collective rather than the individual seems to be stressed at urnfields. The third question concerned the nature of the wider social, cultural and ecological context and the changes therein. This context has been extensively studied the last decade by several scholars, but the results of these studies were never incorporated in a model of the genesis of urnfields. They were therefore summarized and assessed in chapter 5 to create the building blocks needed for generating a Darwinian model of culture change. These building blocks are a model of life history, cultural constraints, social constraints, material constraints, transmission processes and the population structure of a society. The most important findings were that there were no radical changes in the value system and ecological conditions from the Middle to Late Bronze Age. Cultural and material constraints are therefore unlikely to have been a significant 146 force of culture change. A theoretical model was created of the modes of transmission of the cultural variants behind burial practices. In this model the variants were obtained by an individual through vertical and/or oblique transmission by parents and elders in pre-adult life and through horizontal transmission by peers in horizontal life. The group of peers consists of commoners, political leaders and priests. Amongst these peers, political leaders (of an undefined nature) and religious functionaries are the most influential and salient. Priests and political leaders, which are part of a supra-regional community, are likely to be the ones that introduced the exotic variants in the southern Netherlands. By answering the three research questions I was able to create a Darwinian model of culture change that could be checked against the patterns of culture change observed in the archaeological record. 7.2 A Model of Culture Change On the basis of the analyses of the socio-cultural context and the nature of the urnfield phenomenon an individual-level model could be created of the transmission of cultural variants related to burial rituals. In this model the main forces of change were expected to be social constraints in the form of a higher salience and influence of a small group consisting of priests and the most powerful political leaders. Another force are the differences in life history of the carriers of the urnfield variant and the carriers of the barrow ritual variant, giving the former a significant advantage in terms of natural selection as they perform the ritual more often and therefore act more often as a model. Cultural preferences and material constraints were deemed unimportant as there is no evidence for either of them. Cultural preferences - which in evolutionary terms can be called a direct or content-based bias - were, however, the main forces of change in the models of Fokkens (1997) and Gerritsen (2001). Material conditions were considered the cause for change in the group selectionist model of Roymans and Kortlang (1999). The theoretical validity of all three kinds of models was assessed in chapter 6 by embedding the forces of change in a population and extend their effects mathematically over more than one generation. If this is done for the group selection model it becomes clear that culture change as the result of competition among small heterogeneous groups is unlikely to have been the main cause for the adoption of the urnfield burial rite. Although group selection can indeed be a force of cultural change, it takes at least 500 to 1000 years for a cultural variant to rise to high frequency as the result of this process. Similarly, a direct bias cannot have led to the dominance of the urnfield rite in less than 10 generations, unless a different process had caused a 147 high enough initial frequency. So, the earlier models in which either group selection or cultural preferences were considered the single forces of change appear to be theoretically invalid. This leaves us with social constraints and natural selection as forces of culture change. Two types of social constraints were discerned: the higher salience of priests and most important political leaders and the stronger influence of these persons compared to peers. Both kinds of social constraint can be potent forces of change, but only under the following conditions: the weight of the religious and political leaders need to be high enough and the initial frequency of the urnfield variant in the population of leaders has to be higher than that of the barrow variant. Although it is certainly not implausible that these requirements were met in the Bronze Age, there are no empirical or theoretical arguments to suggest they were. And nor need they have been, as natural selection alone provides a potent enough force of change. As the urnfield phenomenon was practiced 6 to 7 times more often than the Middle Bronze Age barrow ritual, the chances of the carriers of the urnfield variant to become a cultural parent are equally as high. As a result the urnfield variant can increase to a high frequency in just a few generations. Only when the frequency moves toward maximum will this process slow down, but then other forces, such as social constraints and direct bias, can contribute. 7.3 Epilogue The finding that natural selection was the main force of culture change may perhaps be counterintuitive for most archaeologists, as we tend to assign much weight to socio-cultural explanations. However, this is an outcome in line with my intentions. This thesis was not intended as only a study of the genesis of urnfields, but also as an experiment. First of all, research in the last two decades in the Netherlands can be characterised mainly by a focus on the local and short-term, with socio-ideology as important subject. The studies of Gerritsen (2001) and Fontijn (2002) are good examples of this. Although the long term is certainly not forgotten in these studies, it is not the main focus and when chronological patterns are discussed it is mainly as a series of synchronical snapshots. So in this study I wanted to assess the value of these studies for analyses of long-term processes. Secondly, I wanted to find a theoretical framework that allowed archaeologists to analyse long-term processes without having to rely on intuition and verbal reasoning. The mathematics of Darwinian models of culture change provided a means to do this. To create such models a proper understanding of social and cultural context is needed, however, which instantly gave me the opportunity to assess value of the previous mentioned studies of the local and short-term, which have just these contexts as their subject. 148 In this regard the study has generated several useful results. Most importantly, it has been shown that mathematics can significantly aid our understandings, as long as our models are based on a proper understanding of how culture changes. Many archaeologists hesitate to use mathematical models, because they remind us of the often faulty systemic models of the New Archaeology (see for instance Johnson 1999 for an overview of the critiques on systemsthinking). In these models culture change is always the result of group adaptation, while the postprocessual critique has taught us that change originates with the individual (see chapter 2). A mathematical model therefore has to start with such methodological individualism. When it does, it can provide invaluable insights on long-term processes that are simply to complex to work out intuitively. Insights that might seem counterintuitive, as in our case of the genesis of urnfields. The use of Darwinian models has also showed that the contextual studies done in the Netherlands the last two decades are indeed invaluable. They provide us with a needed understanding of the socio-ideological context. However, they do appear to be a bit one-sided. Because of a focus on socio-ideology, a developed politics and demographic is lacking. This is in fact a critique on post-processual studies in general (see chapter 2). When it comes to an understanding of socio-political structures we therefore still have to resort to prestige-good models and world system theories, as interpretative archaeologists are eager to critique these models, but reluctant to come up with a new one. So as an experiment I consider this study successful. As an answer to the main research question - why was the urnfield phenomenon adopted in the southern Netherlands? - there are points of improvement, as is to be expected for an experimental study of a subject as complex as the genesis of urnfields. In this thesis the model of the socio-cultural structure and the used equations were purposely kept simple and stylized, in order to get a clear idea of the effects of just a small set of significant variables. However, in order to easily test and improve the models and equations presented in this study I have tried to make most assumptions explicit. Obvious points of improvement are the model of routes of transmission, the dynamics between supraregional and local communities, and the relations between individuals with different social roles in the process of cultural transmission. Subjects that deserve to be studied in their own right. 149 150 Summary At the end of the Middle Bronze Age significant changes occur in the burial rite throughout north-western Europe: the rite of burial in solitary barrows gives way to extensive cemeteries called urnfields. This change is usually characterised as a marked reorientation in spiritual life, thought to represent a new era of “spiritual revolution” and “uniformity of beliefs” across the continent. Indications that in several regions the changes in burial rites were gradual and that the practices and beliefs of the funerary rituals differed between places, is reason, however, for a reconsideration of current explanations of the genesis of urnfields. To do this the southern Netherlands is chosen as a case-study for this thesis, because of the availability of many excavated urnfields and 14C dates from this region and its well-studied socio-cultural context. Models have been put forward to explain changes in burial ritual in this region, but a serious theoretical problem is their inability to get from short-term, individual-centred scenarios to longterm, structural changes. To overcome this problem a different theoretical framework was adopted in this study, in which long-term processes can be analyzed by Darwinian, mathematical models of culture change. Three research questions needed to be answered to find out when, how and, most importantly, why the urnfield phenomenon was adopted in the Southern Netherlands. The first question concerned when, where and in what form the elements of the urnfield phenomenon were introduced in the Southern Netherlands.

Also the changes came about as a package, probably introduced from areas Rhine upwards. As the first examples of urnfield burials date to the beginning of Ha A and the last convincing examples of typical Middle Bronze Age barrow burials date to the end of Ha A, the urnfield phenomenon must have become dominant in less than 200 years. The second question concerned the ideas and beliefs behind the different elements of the urnfield phenomenon. The kinds of personal and communal identities expressed at the burial grounds were examined. To see how personal identities were constituted the meaning of grave 151 goods were traced by reconstructing the biography of the items. It appears that both metals and ceramic vessels were of a local style, signalling no apparent major distinctions in social role or status - differences are expressed in a local, egalitarian idiom.

It was found that social constraint can be potent forces of change, but only under the following conditions: the weight of the religious and political leaders need to be high enough and the initial frequency of the urnfield variant in the population of leaders has to be higher than that of the barrow variant. Although it is certainly not implausible that these requirements were met in the Bronze Age, there are no empirical or theoretical arguments to suggest they were. And nor need they have been, as natural selection alone provides a potent enough force of change. As the urnfield phenomenon was practiced 6 to 7 times more often than the Middle Bronze Age barrow ritual, the chances of the carriers of the urnfield variant to become a cultural parent are equally as high. As a result the urnfield variant can increase to a high frequency within 200 years – the period of time in which urnfields became dominant. Mathematics shows that the forces of change suggested in earlier models, like group selection or cultural preference, require too much time, unless other forces are at work simultaneously. 153 154 Bibliography Anscher, T.J. ten 1990.
