1 Perceptual organization in visual art Jan
Perceptual organization in visual art Jan Koenderink To appear in: Oxford Handbook of Perceptual Organization Oxford University Press Edited by Johan Wagemans 1. Introduction 1.1. Definition of “visual art” “Art” is not necessarily defined by an aesthetic dimension. A sunset may evoke aesthetic experiences, so may flowers, or butterflies, but natural phenomena are not art. One might suppose that art is necessarily of human manufacture. But if someone points out a sunset to you, what is the difference with pointing at a urinal, as Duchamp famously did [1]? The sunset was certainly not manufactured, but merely pointed out. So was the urinal. If the urinal is appreciated as an objet trouvé [2] admitted as an objet d’art), then why not the sunset, the flower, or the butterfly? The single common factor appears to be that art is intentional [3], it implies an “artist” who may, but need not be a manufacturer. This is indeed a necessary requirement, but it is not sufficient (see below). I first introduce a few important distinctions. “Visual art” is art that is meant to be looked at, instead of being heard, felt, etc. But consider that a copy of The Brothers Karamazov is meant to be looked at too (you are supposed to read it), but is generally not reckoned “visual art”. Yet Fyodor Dostoyevsky *4+ was certainly an artist, and his novel is ART. Likewise the famous Fountain (Figure 1: actually a “found” urinal) displayed by Marcel Duchamp in 1917, is art, but not “visual art”. It appeals to cognition and reflective thought, rather than immediate visual awareness. Today, conceptual art [5] holds the floor. This is indeed the politically correct thing to do in a democracy, because most people “see with their ears” as my artist friends say. However, this chapter is focused singularly on visual art, ignoring conceptual art. Note: Square brackets like “*123+” refer to supplementary notes. These notes contain useful additional material and explanation. They are available on the Internet. 1 Figure 1. Left: Marcel Duchamp in front of his Fountain. The fountain dates from 1917 submitted to the exhibition of the Society of Independent Artists. It is an intentionally scandalous “work”, signed “R.Mutt” (German: Armut, meaning “poverty”). The “original” has been lost, but it can easily be “replaced” (some “copies” authorized by the artist) as the numerous museum copies show. The work has been hailed as a summit of twentieth century art. Right: Picasso's Tete de taureau from 1943. According to Picasso: Guess how I made the bull's head? One day, in a pile of objects all jumbled up together, I found an old bicycle seat right next to a rusty set of handlebars. In a flash, they joined together in my head. The idea of the Bull's Head came to me before I had a chance to think. All I did was weld them together … [but] if you were only to see the bull's head and not the bicycle seat and handlebars that form it, the sculpture would lose some of its impact. (Brassai, George (1999). Conversations with Picasso. University of Chicago (from original published 1964), page 61.) The bull's head was displayed at the 1944 Salon d'Automne (see http://en.wikipedia.org/wiki/Salon_d%27Automne) in Paris, catalogued as “Bicycle Seat”. It was removed because of negative reactions of visitors. Although one should not fail to distinguish sharply between “visual art” and “conceptual art”, this may not always be easy, because many paintings from Western art are both. Raphael’s Sistine Madonna (*6+ (Figure 2: La Madonna di San Sisto, 1513/4) is meant to be looked at, and manages to strike an immediate visual impression. Yet it was commissioned as an altarpiece, and has obvious religious connotations. It is art, both visual and conceptual. To someone coming from a non-Western culture the conceptual part may be nonexistent, to such an observer the painting is pure visual art. The same applies to the Western appreciation for African tribal art as visual art, whereas it was intended as conceptual. Figure 2. La Madonna di San Sisto, or the Sistine Madonna by Raphael (Raffaello Sanzio da Urbino 1483-1520). It was finished only a few years before his death, ca. 1513-1514, as a commissioned altarpiece. It was his last painting. A good way to obtain an understanding of the difference between conceptual and visual art is to mindfully consider Duchamp’s Fountain, as compared to Picasso’s Bull [7](Figure 1). Consider the nature of the intention of the artist, and the impact on the observer. These instances are as far apart as can be, although both consist of pieces of junk, with hardly any workmanship on the part of the artist. Yet a more evident contrast is hardly possible: the artist’s intentions were categorically different. 2 As everyone knows from the newspapers, art has an important economic dimension, and indeed one pragmatic definition of art is that it has a value on the art market. When a tin of shit (Piero Manzoni’s Merda d’artista [8](Figure 3, 1961) sold for £97,250 at Sotheby’s in October 2008 (tin #83 of 90; the cans were originally to be valued according to their weight in gold - $37 each in 1961) this thus marked it as a piece of Art. The value on the art market is important for both visual and conceptual art. It is often considered a metric on artistic value, comparable to the citation count in the case of scientific contributions, and making similar sense. This definition places works of art in a single category with rare coins and postage stamps, evidently unfortunate. What is lacking here is an “observer”. The investor is not an observer, in fact, is likely to store the artwork in a vault. Here we identify another necessary condition for designating some objects “art”. Figure 3. Piero Manzoni (1933-1963; http://en.wikipedia.org/wiki/Piero_Manzoni), Merda d'artista, N4, 1961, Diameter 6,5 cm. This is perhaps best explained with an example, I use the case of pictures. What exactly is a “picture”, a painting say? It was famously discovered by Maurice Denis [9] that a painting is (among more) a physical object: “It is well to remember that a picture before being a battle horse, a nude woman, or some anecdote, is essentially a flat surface covered with colours assembled in a certain order.” However, used as a tea tray, such an object is certainly not a picture. In order to be a picture, there should exist a double-sided intentionality, namely – the picture was intended by an artist to be looked at as a picture; – the picture is looked at as a picture, by an “observer”. “Looked at as a picture” implies looking “into”, and entering a “pictorial world” *10+. Consider some examples. An ancient stained wall is not a picture, even though it might beat a Jackson Pollock [11] in attracting visual interest. It is not, since the artist is lacking. No work of art comes into existence as a cosmic accident. Designating the wall an objet trouvé [2](Figure 4) might provide an artist's intention [3], although this in no way changes the wall as a physical object. People have discovered striking renderings of the face of Jesus in trees, old rags, cookies, and the wood grain of toilet doors [12](Figure 4). These are not to be counted as works of art, since the artist’s intention is lacking. 3 Figure 4. Left: Mold on an old wall. Right: “Jesus's face” spotted on the toilet door in Ikea Glasgow. The Face of Jesus has been spotted in the most unlikely places. These portraits are evidently “painted in the mind”, although they often give rise to rumors (media attention, by newspaper, radio, TV, …) of miraculous events. The observer's intention is just as necessary. In a hilarious painting by Mark Tansey [13], a cow is forced to look at a painting by Paulus Potter by several earnest looking men (Figure 5). The cow remains apparently unaware of the explicit erotic overtones of this work, thus one concludes that in the bovine universe the painting is just another object, despite its lifelike size and color. The observer is lacking, because the cow is looking “at” instead of “into” the painting. In this setting Potter’s work is just an object. Figure 5. Left: Mark Tansey’s (born 1949) The Innocent Eye Test, 1981. The cow is looking at Paulus Potter's (1625-1654) Right: The Young Bull, 1647 The cow remains apparently unaware of the explicit erotic overtones of this work. One concludes that in the bovine universe the painting is just another irrelevant object, despite its life size and lifelike color. (Keep in mind that this figure reproduces a painting, rather than a “documentary photograph”!) Depending on the art-form, the physical object matters. Although no mere physical object is a “work of art”, it may provide “a link” to it. Examples are roman marble copies (mere pieces of stone handiwork) of original Greek bronzes [14]. Without such a link, the work of art (in the intention of the Greek authors) doesn't exist anymore. Without the double-intentional significance [15], the physical object is just junk. The double-sided intentional nature thus explains the ontological status of “pictures”. The value on the market is irrelevant. There is much that might well be considered “art” that is either not marketable, or would 4 bring merely some value typical of used goods. Examples are tattoos, ornaments on teacups or weapons, facial makeup, and so forth. In this chapter I take a broad view and consider “art” (used as short for visual art) to be any object, change applied to an object, happening or expression, when it has the double-sided intentionality [15]. Art is designed to affect immediate visual awareness in some specific way. A work of art presupposes a certain “visual literacy” in order to be “read”. It is a hermeneutical task *16+, in George Steiner’s *17+ terms “not a science, but an exact art”. Steiner’s “four movements” indeed apply to art appreciation: First there is the blind trust to find something there, a step into the dark, for better or for worse. To find nothing is experienced as a painful breach of trust. Then there is an act of aggression, as the observer “conquers” the work, followed by incorporation, as the observer makes the work its own. Finally, there is retribution, wherein the observer (as indeed with the initial trust) honors the artist’s intentions. The work is recreated in the observer, albeit in novel form, for “to understand is to decipher; to see [orig.: hear] significance is to translate”. Exact recreation is impossible, the artist’s meaning is always lost. Each observer sees only itself. My central interest will be modern Western art (which involves the art of Western Europe of the late middle ages till the present, the art of the U.S. since the sixteenth century, etc.), especially painting, sculpture, and architecture. I will also occasionally touch on non-Western art, and other fields of endeavor such as photography, cinema, fashion, graphics design, and so forth. Of course, the interest is merely visual organization, I ignore the conceptual, magical, religious, and so forth, connotations, even though these are often the very reason for the being of the art. I focus on Gestalt properties, that is on the nature of the organization of the work, to the extent that it may be considered “visual” *18+. Although there are certainly works of art whose organization is almost completely visual, in many cases there exists organization on many simultaneous levels. I start with making some (minimal) distinctions. 1.2. The stratified structure of works of art I again use the case of pictures as an example. Pictures sometimes carry ideal meanings, not unlike poems, although this is not necessarily the case. Here I am mainly concerned with an “anatomical” analysis. Pictures may be analyzed as composed of mutually heterogeneous levels of “being” *19+, of which I identify four major (from the perspective of visual organization) ones (Figure 6). Figure 6. Three drawings by Salvador Dali (1904-1989), all representing human figures. These drawings have significant structure on all four ontic strata. At level 1. Smallest relevant constituents we find a mixture of short strokes and blobs in the left, flowing, curved strokes on the center, and blobs in the right drawing. 5 At level 2. Simple meaningful units we find outlined, convex, “shaded” figures, volleys of vertical hatching, and a pencil of concurrent straight lines in the left, repeated curved “trial” outlines, and oblique hatching in the center, related blobs and horizontal hatched shading in the right image. At level 3. Salient Gestalts we encounter mutually aligned “stones”, and a deep floor in the left, ovoid, related volumes in the center, and parts of human figures (torsos, heads) and floor in the right drawing. At level 4. Represented entities we find human figures in all three drawings, the left and right one evidently located on a groundplane. The left figure has a complicated spatiotemporal “story”, the center drawing is striking because of the dynamic pose of the figure, the right one represent a “mother and child” scene, with a clear emphatic relation between the two. Level #1. Smallest relevant constituents These are the strokes of a drawing, the touches of a painting, and so forth, as they are visually evident. These are essential infima, the structure of the paper or canvas often being noticeable, but seen as part of the physical object, rather than the double-intentional picture. If the maker intentionally chooses a physical texture (rough paper, film grain) such that it becomes part of the work, it is considered an objet trouvé. Level #2. Simple meaningful units Here one thinks of mutually dependent pairs of strokes, sets of touches making up an edge, and so forth. “Meaningful” involves a spontaneously felt relation in immediate awareness. A single stroke may well be a meaningful unit, but sometimes the simplest units contain many strokes. Level #3. Salient Gestalts Any number of simple meaningful units may cohere in Gestalts. These do not necessarily stand for nameable parts. If they do, the naming comes afterwards, as cognition kicks in. They appear in awareness as significant geometrical configurations, or even volumetric entities. These Gestalts often fluctuate on prolonged observation, as microgenesis organizes the presentations. The work may actually prevent microgenesis from ever reaching a “fixed point”. Level #4. Represented entities These are perceived objects, events, states of affairs, in some cases plots or stories. The spectrum is huge, this merges into the domain of reflective thought. None of these strata is necessarily present in any given instance, although they may all be simultaneously relevant. The profile of weights that might be placed on the strata is a useful indicator of style. It varies widely, as one notices in mutually comparing works by Mondrian [20], Pollock [11], Malevich [21], Rubens [22], and Botticelli [23], for instance. One may associate different aesthetic values, either positive or negative, with the strata. But what is more important, is that the strata are never seen in isolation, except for special cases, like art restoration work – but then the work is not a “picture” in the sense used by me. Pictures are organic wholes, implying that the strata are mutually interdependent [24] (Figure 7). There appears to be a two-way causal flow [25]. A superstratum contributes context to objects or processes in a substratum, whereas a substratum contributes substantial qualities to objects of the superstratum. In this way, paintings may be comparable to polyphonic harmonies. Notice that there is room for both harmony and disharmony, a crucial point in aesthetic appreciation. Of course, this may be more easily noticeable in a Rubens painting than in a work by Malevich, simply because of their very different structural complexities. 6 Figure 7. Paul Klee (1879-1940) Brother and sister, 1930. Notice that the siblings hold a single heart in common! The drawing has a very tight structure, only a supersurgeon might separate these Siamese twins successfully. This drawing is an amazing example of an organic whole with the various ontic strata intimately interconnected. It will repay close study. 2. Some illustrative instances 2.1. Ornamental patterns Perhaps the purest examples of visual art are ornamental patterns [26]. These range from very simple, like an intentional scar, tattoo, or war paint, to extremely complicated, like the ornamental tessellations of the Alhambra [27]. The simplest ornamental patterns are found in all cultures worldwide. They almost invariably include spirals, used in scarification, tattoos, amulets, and ornamentation. In the West they are perhaps best known as the Celtic symbols [28], found on many Dolmans and grave sites. The Celtic spirals mostly rotate clockwise. One finds both dense (Archimedean) and open (logarithmic) varieties [29]. They also occur in connected pairs and triples (triskele). In modern Western culture one finds these designs in church windows, mosaic floors, emblems, jewelry, and so forth [30]. Very similar designs occur in facial tattoos of the Maori [31] (Figure 8), African scarifications [32] (Figure 9) and jewelry (earrings), Navaho sand paintings [33], Australian aboriginal art [34], and Japanese family emblems [35]. 7 Figure 8. A Maori man by Parkinson, Sydney (1745-1771). Parkinson was the artist on Captain Cook's 1st voyage to New Zealand in 1769. From: Parkinson, Sydney. A journal of a voyage to the South Seas. London, 1784, plate 16, opposite page 90. See http://en.wikipedia.org/wiki/File:MaoriChief1784.jpg. Figure 9. Example of traditional African scarification. See http://www.ezakwantu.com/Gallery\%20Scarification.htm. Although this example only shows the face, scarifications often cover the whole body. The spiral has a very simple organization, not much more complicated than a line. However, it manages to cover an arbitrarily large area in a manner that is immediately visually evident. One might say spirals render an area visible. Other ways to render areas is by (usually regular) stippling, or (usually regular) hatching, also common, and visually evident patterns. The double and triple spirals are composite patterns, yet immediately recognized as unified designs. They cannot be arbitrarily extended, like the single spiral. Thus, they naturally fit within a circular outline. Concentric circles, ornamental knots, mazes and labyrinths fit into the same overall family of visual organization. They are found as ornamentation on bodies, weapons, pottery, jewelry, floors and walls. They serve as family emblems, powerful symbols (the swastika of the Third Reich falls in this class), and so forth. Another important class of ornamentation that often has strong perceptual organization is that of the band patterns. It occurs in Europe from the stone age on [36], and is found worldwide in virtually all cultures. It naturally occurs at the boundaries of disks, and as “bracelets” on rotationally symmetric objects like arms, pots, and sticks. In the simplest cases one finds parallel lines, often zig-zag, or wavy. In more complicated cases one finds repeated localized configurations. The repetition is often “with variations”, usually regular ones. Most typical are simple alternations, like in the “egg and dart” pattern *37+ already found at the Erechtheion (ca. 421 BCE [38]). Formally, the organization is defined by the “frieze groups” *39+, which is the class of infinite discrete symmetry groups for patterns on a strip. There are seven different frieze groups. The groups are built on translations and glide reflections, one may find additional reflections along the translation axis, and half-turns. These basic organizations are found in ornamental borders of the most diverse origin (painted, or scratched in pottery, in basketry, in “barbed wire” tattoos, in tile borders, and so forth), all over the world, in the most diverse cultures. Although the repetition with variation is indeed visually salient, there is little indication that the taxonomy of the frieze groups plays an important role in visual organization [40]. It is apparently not part of a “visual grammar”. The patterns that are being repeated are necessarily “local”. They are often abstract geometrical forms, like circles or crosses, that may also be used for their own sake. Indeed, starburst patterns, circles (concentric, or 8 intertwined pairs or triples), and especially crosses, are found in all cultures. Crosses are especially common, even in non-Christian (due to distance in space or time) civilizations. These simple configurations have frequently been given meaningful interpretations (circles and starbursts standing for the sun, crosses for human copulation, and so forth), but it would seem that the visual salience preceded such meanings (which indeed can vary). The basic forms are also found in the colorations of animals and plants, think of the “eyes” found on butterfly wings. The “releasers” that evoke standard action patterns in birds and fishes are often based on similar patterns. In more advanced cultures one often encounters stylized images of floral motives, animals and man. Such stylizations are frequently based upon one of the basic forms though, that appears to give them their impact. It would seem that these forms are indeed part of the “visual grammar”. Their common property appears to be simplicity (minimal structural information content), combined with high non-accidentalness (see also van der Helm on simplicity, this volume, chapter 57). In two dimensions one obtains the “wallpaper patterns” *41+. Again, their organization can be fully formalized through the symmetry groups in the plane. There are seventeen distinct groups, as has been known since 1891 [42]. All were already used by the ancient Egyptian craftsmen! Indeed, these groups have been invented by many cultures, worldwide. Fabulous examples are found in the tilings of the Islam. The Alhambra is the paradigmatic example (Figure 10). I know of no comprehensive accounts on the visual perception of these patterns. It seems unlikely that naive observers would spontaneously differentiate between the various types. As with the frieze groups, there is little indication that the taxonomy of the wallpaper groups plays an important role in visual organization. It is not a part of “visual grammar”. Figure 10. Example of a sophisticated tiling pattern from the Alhambra. See http://en.wikipedia.org/wiki/. The Alhambra is a treasure trove of such tesselations of the plane. The reason is, no doubt, that the Islam forbids the depiction of reality. Thus the artists either design all kinds of abstractions of Koran writings, or they move towards ornamental patterns. Of course, mural tile work is perfectly suited for that. A particularly simple manner to induce perceptually salient organization is by bilateral symmetry about a vertical axis [43] (see also van der Helm on symmetry, this volume chapter 17). This works with virtually any pattern, witness the Rorschach inkblot figures [44] (Figure 11). Such patterns are localized and are easily fitted into various bilaterally symmetrical regions (coins, round emblems, square tiles, heraldic patterns, vases, …). Although heraldic symmetry is often very strict, e.g., spread eagles getting two heads, one looking left, one looking right, heraldic trees are often not quite bilaterally symmetric. They don’t need to be, because they “simply look it” anyway (Figure 11). With some degree of scrutiny you can make out the difference, but this has no relevance to the Gestalt. “Just looking” reveals a “visual symmetry”, even if it (strictly speaking) isn’t there. 9 Figure 11. Left: Card 2 of the Rorschach test. Some popular responses are “two humans”, “four-legged animal”, “animal: dog, elephant, bear”. The website adds: “The red details of card II are often seen as blood, and are the most distinctive features. Responses to them can provide indications about how a subject is likely to manage feelings of anger or physical harm. This card can induce a variety of sexual responses”. See http://en.wikipedia.org/wiki/Rorschach_test. Right: A drawing by Alphonse Mucha (1860-1939). Notice the apparent symmetry. This “symmetry” does not survive scrutiny, or even a good look. Yet the symmetry is obvious at first glance! Perhaps unfortunately, we don’t have much of a “psychophysics of the cursory glance” today. Bilateral symmetry about a vertical axis again combines minimization of structural information content (a mere “etcetera” suffices) with remarkable non-accidentalness. Faces (as seen en face) are the most important instances of bilateral symmetry from a (human) biological perspective. Given almost any bilaterally symmetric blob, human observers are likely to “see” a face in it *45+. This fact (though rarely acknowledged explicitly) is of the utmost importance to the visual arts. Especially the female gender of Homo Sapiens specializes in optimizing the ideal “face” configuration (see also Behrmann et al., this volume, chapter 30). Ideal faces are perfectly bilaterally symmetric of course, whereas no actual face really is. Bilateral symmetry is a visual organization that readily arises in vision, even when the actual patterns are far from “ideal”. Apparently it has a marked template character (see also Koenderink on Gestalts as ecological templates, this volume, chapter 59). Humbert de Superville *46+, in his “Essai sur les signes inconditionnels dans l'art” (Leiden, 1827) lists the most important visual organizations of the generic face. This is perhaps one of the more interesting treatises from the perspective of experimental phenomenology. 2.2. Fashion Human figures are easily the most important objects for the human observer. Virtually all humans are “artists” in that they intentionally shape and decorate their bodies such as to evoke certain gut level visual responses in others. Methods may aim at eternity (witness mummified Maori heads), a lifetime (scarification, tattoo, skull deformation, …), a short period (seasonal fashion), a mere occasion (makeup), or just a fleeting moment (intentional smile, slightly bending the arm in order to de-emphasize the elbow joint by Victorian ladies, articulating the finger pattern, …). Most of these methods immediately address the momentary visual awareness of others. Both faces and bodies yield strong Gestalts. Paintings and sculptures can be seen as 10 carrying on body display “by other means”. Most facial “make up” is aimed at evoking emotional responses, often of a sexual nature, in others. This generally implies the accentuation of desirable “releaser” patterns *47] (Figure 12), that is to say, accentuations of the natural countenance. Comparatively rare exceptions include the make-up used by the military to visually merge in the environment (camouflage *48+), and tribal “war paints” that are supposed to induce fear in opponents, or, perhaps, promote courage, or recklessness, in the wearer. The camouflage techniques reverse the usual make-up techniques, by deemphasizing eye and mouth, and even optically defragment the face. The dark eye-stripes [49] encountered with many prey animals similarly deemphasize the eyes, which are otherwise salient indicators of animal presence. Apparently the laws of visual organization rule throughout the animal kingdom (see also Cuthill & Osorio, this volume, chapter 45). Figure 12. Make up scheme (Yauheniya Piatkevich-Hauss #11865306). Such “face charts” (for various complexes) can be found all over the web. This one is at http://depositphotos.com/11865306/stock-photo-Make-up-scheme.html. Such charts clearly reveal the releaser function of make up. Niko Tinbergen (the ethologist) made similar schemes for various bird heads. A steady component of female make up is the accentuation of the eyes, usually by darkening, or coloring the eye sockets, evidently with the intention to draw attention to them. It is known from ancient Egyptian, Greek and Roman remains. This sometimes includes taking drugs (Atropa Belladonna [50]) in order to dilate the pupils. Another steady component is overall face color (white in the Japanese geisha, brownish in modern Western women), hairline (shaving in the middle ages), hair silhouette (cutting, braiding, binding, …), and hair color (tinting). Usually the mouth receives a strong accent (much like the eyes), involving lip color, shape and size. These components define the overall first impression. They cause the face to “read” clearly, even at a cursory glance. They also introduce a “style” (e.g., compare the classical geisha, the ancient Egyptian women, the modern Western young urban professional, …), thus they intentionally set out to trigger specific visual organizations. More volatile fashions aim at the shape of the face (false shading to accentuate bony structure, rouge to raise the cheeks, powder to kill a highlight on the nose, and so forth). In some cases actual ornamentation may be added. All this is carefully orchestrated so as to evoke a highly organized perception in immediate visual awareness. That these facial Gestalts are to a large extent conventional becomes evident by widening the scope beyond one’s daily social environment. Different cultures often use fully different methods, even your own culture changes over time, both on the short and on the long term. As one compares painted portraits over the centuries one encounters remarkable uniformity over an era, but great diversity over longer time spans. In more recent times we have photography and cinema, yielding detailed and veridical data. Of course, one has to “correct” for various photographic techniques here, the cameramen typically adding their own job of “make up” in a purely optical way. With only moderate experience you will be able to date a face accurately, hardly being off by a decade, usually getting it right within a few years. The such-and-so-decade look [51] can be picked up at a glance, and is mostly a matter of visual organization. 11 Theatrical make up uses the same techniques [52], but in a highly condensed manner. The face should “read” in the intended manner even from a great distance, and in all light. Despite their differences, the methods of stage make-up and glamour make-up are only quantitatively different. Both aim at creating a strong visual Gestalt of some desired kind, say of age, character, or profession. What goes for the face ipso facto holds for the body [53]. A person may control the visual impression of the body through assuming certain (studied) poses, moving in particular ways, and so forth, and by accentuating or hiding various features by way of appropriately chosen dress. If there is an ample layer of fat, “foundation” (corsetry, bras, …) may work wonders “behind the scene” (optically, that is). These are deployed so as to influence the immediate visual impression of others. Again, going through Western painting throughout the centuries (not to speak of non-Western cultures!) reveals an amazing variety over time, especially as concerns the female gender of the species. The male gender appears to vary predominantly through different conventional clothing, whereas the female actually appears to vary in body shape, as is evident from the rendering of humans in the nude. Yet this is evidently nonsense! From a biological perspective, it is evident that the female Homo Sapiens has (anatomically and physiologically) not changed that much during historical time. Going through a selection of paintings forcefully shows that the body image is a conventional Gestalt. It is of vital importance in society, and it also pervades the visual arts, both in sculpture and in painting. One might say (as is the case with the ornaments discussed above) that the body image is a meme [54]. It is not different from (and closely related to) “fashion” in clothes. Memes are comparatively stable “mental images” (or schemes), that are somehow “contagious”. They apparently spread from person to person within a time-slice of culture, and soon become traditionalized. One witnesses changes that seem comparatively fast as compared to the lifetime of an established meme. Almost by definition, all memes of interest to the present quest are especially good Gestalts. Here is a striking example of such a sudden “transition”. The female body image throughout (visually) recorded history is roughly characterized as a vertical column with some conventional modulation of the silhouette (accentuated belly and short legs in the Western middle ages, flat belly, narrow waist, and wide hips (“36-24-36”) in contemporary times) with a structured upper part (breasts, shoulders and head). The columnar nature is emphasized in Egyptian, Greek (kore), and Roman art, to be continued in the Western middle ages all the way up to the twentieth century. The long robe is the dress that highly accentuates this by hiding the legs, thus delineating the column rising from the floor. Trousers came only recently. In 1961 Marilyn Monroe [55] wears jeans [56] (and even a bikini - invented by Louis Réard in 1946 [57]) in The Misfits [58]. Her penultimate act is an emotional solo performance. She intentionally keeps her legs together, although she goes through emotional contortions, mainly bending in hips and knees. Michelangelo Antonioni’s Blow-Up [59] dates from 1966, only five years later. One notices that the photographer’s models are instructed to pose with legs widely apart, poses that are orthogonal to the classical ideal. Jean Shrimpton [60] (“the shrimp”) and Lesley Lawson *61+ (“Twiggy”) set the scene in the fashion world of that period, and introduced a novel model of the modern female. The poses became angular, emphasizing knee and elbow joints, which tended to be played down in the past. Fashion accentuated the effect through strategically constructed sleeves, and stockings, striving for an androgynous effect. Designers often forced the models to wear caps, causing them to look like young boys in the awkward age. Remarkably, this changeover occurred in just a few years. Pre-sixties and post-sixties photographs of women are impossible to confuse. The fashion (graphics) artists immediately followed suit. Soon modern visual artists did the same. The particular revolution described above gave rise to major changes in the composition of fashion photographs. This can be nicely monitored from Antonioni’s Blow-up photo sessions [59]. Instead of the composition involving the single figure (essentially a Greek sculpture), or the small group (say the Three Graces *62+), the composition involves an arbitrary number of models that repeat (or play upon each other’s) awkward poses. In case a single model is photographed the angular pose is usually related to the picture 12 frame, or suitably arranged props. In this way one obtains again a well organized perceptual organization, albeit of a completely different kind than the generic perceptual organizations from before the transition. This illustrates that strong compositions are possible in any “style”. No photographer could avoid the change, as a study of the work of the well known fashion photographers reveals (study Richard Avedon [63] (Figure 13) as an example). Figure 13. Left: Richard Avedon (1923-2004), Vogue 1957. Right: Richard Avedon, Vogue 1967 (the model is Veruschka, Vera Gräfin von Lehndorff-Steinort or Veruschka von Lehndorff, born 1939) Richard Avedon was a major, very creative photographer, not someone slavishly following the mainstream. He tended to set the fashion. He did not invent the sixties “twiggy” look. Yet, comparing the photographs, the left one is obviously “fifties”, the right one equally obviously “sixties”. Apparently, Avedon too, fell prey to a powerful meme. The figure at left rises from the ground as a Greek kore, except for the position of the arms (which do in no way “stick out”, but harmoniously continue the flow of the thorax), whereas Veruschka is in a dynamic pose, with her extremities stuck out in opposition to the trunk. The latter feature is equally visible in static poses of the sixties (some poses were no doubt hard to “hold”), it was a major aspect of the “sixties look”. 2.3. Sculpture Sculpture is the art of composition in three dimensions. Here we mainly focus on the classical bronze, stone and wood sculptures, although the realm of “sculpture” has been greatly expanded in recent times. Moreover we concentrate on simple works (busts, figures, putti, single animals, …), and ignore most groups (like Rodin’s Burghers of Calais *64+), or extended scenes (like Bernini’s St. Theresa [65]). Some dyadic and even triadic topics are readily regarded as “simple” though, think of “the three graces” *62+, “mother and child” (e.g., Isis with Horus, Mary with Child Jesus, …), or “woman with male corpse” (e.g., Pieta, …), in one of the conventional poses. Sculpture is all about perceptual organization. Although one may display the plaster cast of an object as a “sculpture” (not uncommon in our era), this is evidently conceptual art, not different from displaying a urinal. Sculpture proper is “architectonic”, it is about the composition of volumes and surfaces. The (late) nineteenth century German sculptor Adolf von Hildebrand [66] published a theory in 1893, that was ridiculed (and acclaimed by others) at the time. He is only interested in “naturalistic” work. He distinguishes sharply between the Daseinsform and the Wirkungsform of volumetric objects. The Daseinsform is what might be called the physical presence of an object. It enters awareness through movements of the vantage point (binocular vision, moving around the object, or looking at the manipulated object). Thus, it is not a thing of immediate visual awareness, but a cognitive construction on the basis of many successive awarenesses. The Wirkungsform is an artistic construction that works from a single viewpoint, immediately. This involves architectonic thinking on the part of the artist. The artist has to understand microgenesis. The observer should appreciate the view as 13 “natural”, and be able to capture it in immediate visual awareness. As Hildebrand observes, children’s drawings work immediately. He concludes that the Wirkungsform should include what makes the children’s drawings work. Thus, sculpting is not about copying nature. It is about affecting human visual awareness. He mentions the “Grecian nose” *67+ as an example (“… it is not as if the Greeks had noses like that …”). Most Western sculpture made before WW-I is “volumetric”, and can be largely understood in terms of an overall composition based on a small number of simple (ovoid, cubical, or cylindrical) major forms, smoothed together and elaborated by way of surface relief. Here “surface” should be understood in a very broad sense. Thus – for visual purposes – a cube can be understood as essentially a sphere (a compact volumetric object with aspect ratios roughly 1:1:1), with a superficial “dressing” of corners and edges. The overall composition is due to the mutual relation of the major forms, and is retained when the sculpture suffers through weathering, and so forth, as is often seen in old (non-restored) works. Even the overall configuration usually yields a strong cylindrical, ovoid, or block-like impression [68] (Figure 14). Exceptions (e.g., horse rider, boy with dolphin, etc.) are usually seen as “groups” of pieces that might exist as individuals. The relations between group members are of a higher order than the relations between the sub-volumes of a single member. Figure 14. Left: The Egyptian piece at left is almost a cubical chunk of stone (man called Ay Second Prophet of Amun and High Priest of the Goddess Mut at Thebes, Limestone, XVIII Dynasty, 1336-1327 B.C.E., Brooklyn Museum). Center: Peplos Kore from Paros (c. 530 BCE, Acropolis Museum). Right: The Venus de Milo, Greek Hellenistic, ca. 100 BCE, Louvre. Notice that so called “abstraction” comes first, so called “naturalism” only in later stages. This is entirely typical. Art does not arise from a need for mimesis, it derived from an urge to create something that should hold itself against nature. Naturalism only becomes possible when the artist has “conquered nature”. An interesting instance of variations on a single basic shape are the “character heads” made by the Austrian sculptor Franz Xavier Messerschmidt [69] (Figure 15). By all counts Messerschmidt might be denoted mentally ill, when he produced sixty-four studies of his own head, assuming the most incredible grimaces. There is no doubt a system in this madness, although we remain in the dark as to Messerschmidt’s formal design. What is of interest here is that the basic form, Messerschmidt’s skull, remains constant over the series, whereas the muscular/fatty/skinny cladding varies widely. The set is well documented, and makes a fascinating corpus of work for the study of (sculptural) form. 14 Figure 15. Four “character heads” by Franz Xaver Messerschmidt (1736-1787). At one point of his career Messerschmidt became mentally ill, and started on a project of sixty-four representations of his own head in various states of grimace. The set (most have been kept) is worth close study because these (mutually very different) shapes are all based on a single template, namely the sculptor’s own skull. Later developments in mainstream Western sculpture involve extreme non-convexities. These may take the form of holes (see also Bertamini & Casati, this volume, chapter 10), or are due to the bending of elongated volumes. Such work still retains the overall volumetric character though. Constructivism changed that by introducing non-volumetric elements like wires, rods, and plates. Such work may lead to completely different perceptual organizations, in which the overall, mostly empty space, dominates over volumetric, filled space. If the classical organization is like a rock, the new one is like an empty tree in the winter. The introduction of non-rigidly connected parts in arbitrary movements then destroyed even this static spatial organization. The perceptual organization may be similar to that of a flock of birds. The visual organization changes when you walk around a work, very differently for open and closed sculpture, the reason being that you look through open structures (Figure 16). The constructivists introduced transparent material for much the same reasons. Figure 16. Left: Naum Gabo (1890-1977) Constructed Head No. 2 (1916, original lost). Center: Henri Moore (1898-1986) Helmet No 2 (1950, Staatsgalerie Stuttgart). Right: Alexander Calder (1898-1976) Rouge Triomphant (1959-1963, Gagosian Gallery). The Gabo is constructed from planar sheets, the Moore has been cut through, and the Calder has hardly any “bulk” appearance. Compare the Eyptian piece at 14 left, which is compact, as a pebble. 2.4. Painting With “painting” I refer to any type of essentially “planar” art, be it drawing, embroidery, map making, intarsia, sand painting, you name it. I mainly limit the discussion to works of human, or slightly subhuman, size, and mainly confined to some visually obvious “frame”. The frame may be implicitly defined through paper size, or 15 explicitly as with an actual frame around a canvas, and so forth. In most cases the frame, in whatever form, is an important part of the composition. Paintings as physical objects are arrangements of colors on a planar surface of limited extent. Paintings as artworks may or may not succeed in evoking varieties of visual awareness in observers that suit the intention of the artist. Success or failure depends upon the distribution of colors, at least if the group of observers are in the artist’s intended target group. Thus “composition” is everything [70]. Of course, the range of possible visual awarenesses that the artist might want to evoke is virtually unlimited. To complicate matters, artists had, and have, often secret agendas. Apart from the urge to evoke visual awareness in their intended audience, they often have pedagogic, or idealistic objectives (this includes propaganda and advertisement). Here we only consider visual awareness proper. The best illustrators, propagandists, and so forth, are invariably good artists. They have to be, otherwise their “messages” would not be driven home. For all we care, “pure art” is a nonentity. I simply concentrate on the perceptual organization, and ignore the “message”. This may be hard if the cognitive message is very loud. A thoroughly detached attitude is of the foremost importance. Experimental phenomenology should proceed as a physician performing an autopsy. In studying visual awareness one should be “all eye”. The first impact upon the eye is the composition. The composition is often not noticed by the observer in a conscious fashion, it is always an important part of the artist’s trade though. The composition is why certain images are remembered forever, and others forgotten after so much as a glance. Example of a memorable image is the photograph taken by Joe Rosenthal on the 23rd of February 1945 on Iwo Jima, generally known as Raising the Flag on Iwo Jima [71] (Figure 17). It depicts five Marines and a U.S. Navy corpsman raising the flag of the U.S. atop Mount Suribachi. Three of the five did not survive the battle. The photograph won a Pulitzer Prize in the same year, in 1954 it was used as the topic of the Marine Corps War Memorial (by Felix de Weldon) at Arlington National Cemetery. By public demand it was printed on a postage stamp five months after the event, selling over 137 million (biggest sell of the US Post Office). The photograph has been reenacted, published, painted, sculpted, cartooned, tattooed and so forth, countless times. It is a true public image. Figure 17. Left: original photograph of the raising of the flag at Iwo Jima. Center: the first stamp. Right: a doujinshi (Dōjinshi (同人誌), transliterated as doujinshi, is the Japanese term for self-published works, usually magazines, manga or novels) of the Strike Witches (a mixed-media project originally created by Humikane Shimada via a series of magazine illustration columns; see http://en.wikipedia.org/wiki/Strike_Witches) entitled “Witches No Panties”. Another example is the painting American Gothic [72] (Figure 18) by Grant Wood (1930). Whereas initially the painting raised huge controversy, it soon became a public image. There exist numerous copies (including sculptures), and countless parodies. A postage stamp was issued in 1998. 16 Figure 18. Left: Grant Wood’s (1891-1942) American Gothic (1930, Art Institute of Chicago). Center: a Department of Agriculture Food Bank Debit Card. Right: one of the many parodies (the Web message said: “Paris Hilton, left, and Nicole Richie pose with Tinkerbelle in this undated publicity photo. The friends star in Fox’s new reality series “The Simple Life”, in which Hilton and Richie try to survive on a far. The show airs Wednesday, Aug. 13, 2003 (AP Photo/Fox, Sam Jones)”). Notice how such parodies can (pictorially) be far off (e.g., the left figure is higher than the right one, both figures are female, much younger, the clothes are very different, also in color, the background is fully different, and so forth), yet are immediately recognized for what they are. There seems to be no explicit “reasoning” involved. Apparently the “gist” is very generic in such cases. Why do these images command such public interest, even among people with scant interest in the arts, and even many years after the first publication? It is not just their conceptual meaning, although that evidently plays a role too. It is their immediate visual impact, as the many parodies, many of which are just visual puns, only roughly reflecting the gist of the image, show. Apparently these images “have something” that other pictures lack. The “something” evidently has to do with the perceptual organization evoked by them. The images have a Gestalt quality that easily survives reduction to postage stamp size. The first visual impression is largely based upon the overall “gist” *73+. This gist is retained even in a thumbnail reduction to a dozen by a dozen pixels. Art directors [74] that have to select pictures for magazines often look at reduced images (by printing proof sheets, using a reducing glass, and so forth). It is generally agreed that if an image doesn’t survive such minified viewing it will certainly fail to have “impact”, even when printed large at high resolution in some glossy magazine. Of course, in cases of iconic images, for use in signs, and so forth, the gist may be all there is (Figure 19). Figure 19. Isotypes (International System of Typographic Picture Education) were pushed by Otto Neurath (1882-1945; Austrian philosopher, member of the Wiener Kreis) about 1935 (see 17 http://en.wikipedia.org/wiki/Isotype_%28picture_language%29, and Otto Neurath, International picture language. London: Kegan Paul, 1936. Facsimile reprint: Department of Typography & Graphic Communication, University of Reading, 1980). They were designed by an artist, Gerd Arntz (German-Dutch, 1900-1988; see http://www.gerdarntz.org/). Such pictograms are still widely used all over the world. Most can be “read” at a glance, without any prior instruction. Artists use various kinds of preliminary depictions [75]. The croquis is a gestural drawing of the live model. It is done fast, and captures the essential. The croquis (usually a number of croquis) are used by the artist to design the final composition. The croquis is sought for by the connaisseur because of its sprezzatura [76]. The esquisse [75] is a first sketch. The esquisse is intended to be used by the artist, and is sought for by the connaisseur because it allows a rare insight in the artist’s mind set. The esquisse is often a stronger statement than the finished work. Several (or many) may be made, in order to explore the realm of possibilities of a project. The croquis and esquisse are usually of small size. The ébauche [75] is the underpainting for a painting, it is not intended to be seen, or used as such, since its fate is to be overpainted. It is the size of the final painting. Since it is painted in a much broader style, the ébauche may well be more indicative of the artist’s intentions than the final work though. Famously, the impressionists were accused of passing off their ébauches as final paintings. Thus, the exploration of the gist is usually an important part of the evolution of a work. All these exploratory, or summary statements are of considerable interest to the study of visual organization as it applies to the visual arts. In many cases they may be of more immediate interest than the study of completed works. It is hard to say to what extent artistic development of a work parallels microgenesis of visual perception [77]. Both cases where it apparently does, and cases where it clearly does not, are not hard to find. The impact of an image starts with the gist, but most images, except perhaps gestural sketches, esquisses made in preparation for final works, and so forth, have relevant structures at other scales, that will be revealed under continued observation. Even comparatively simple paintings usually require a “good glance” involving a dozen fixations in order to obtain a preliminary impression. This is not yet full scrutiny, but it certainly moves part of the way to visual cognition. Many of the parts will still be in mere visual awareness though. Their impact on the whole is pre-cognitive and depends upon Gestalt factors rather than cognitive factors. Most images one sees have many layers of scale, and even after scrutiny there is usually quite a bit of “mystery” left, that are structural elements that remain on the pre-cognitive level although one is well aware of them. An understanding of this spectrum that ranges from pure awareness, over cognitive stages to pure reflective thought, is largely lacking. A fact that is often forgotten, or certainly highly underestimated, is that virtually all images are instances from an extremely huge space of possibilities. Consider a low quality image from the internet, it is likely to have a file size of 4kb, implying that it is one of a set of 84000, a huge number. The image is a member of a set of more than 2 103612 possible images. No one has an intuition for numbers like that. You have at most 10 5 hairs on your head. The number of particles in the universe is estimated at 1080, again, much smaller. Remember that is for just a low quality image! Thus, the number of possible images is for all practical purposes infinite. Of course, most of these images “look like nothing”, that is to say are look-alike “noise patterns”. The ones that “look like something” are only a tiny fraction, though still an essentially infinite set. No way you could ever see them all. The “space of images” as explored here is merely the space of physical images, Maurice Denis’ “essentially a flat surface covered with colors assembled in a certain order”. What is really of interest in the present investigation is, of course, the space of visual presentations of a human observer. This is much more difficult to describe, it is a virtual space. This is the space of real interest. The discussion below focuses on this visual space, although I will use the space of physical images to indicate rough ballparks. You identify the style of a painting at a glance, you identify artists from works you never saw before at a 18 glance, you spot a “fake van Gogh” on first sight, and so forth. It is a priori likely that the set of images that are striking on first sight is also huge, but no doubt you haven’t encountered more than a vanishingly small fraction yet, no matter your age. There is still ample room for further development in the arts, so to speak. Perhaps the amazing thing is that “visual organization’’ works as well as it apparently does. However, it seems quite possible, perhaps even likely, that the ability of human observers to deal with images enables them to deal with only a small, singular subset. From the perspective of experimental phenomenology, it is evidently of interest to attempt to attain an overview of the boundaries of human visual microgenesis. This is far more difficult a problem than one might expect. Throughout the history of Western art there have been “paradigm shifts”, not only of a mild character (a style change), but also of a cataclysmic nature. Although hardly imaginable now, the paintings of the early impressionists were considered dangerous enough that pregnant women were kept away from the salon des refusés for fear of miscarriages *78+. The cubist movement, and the work of “Jack the Dripper” *79+, perhaps fall in a similar category. Such occasions can be seen as the conquest of a novel area, previously terra incognita, of the space of images. In the case of the globe one at least had a notion that there was a “white area” somewhere, it could be marked hic sunt dracones [80]. This is not really possible with the space of images. The new area discovered by Jackson Pollock must have felt more like the fear of early seamen to fall off the edge of the (then flat) earth. Many of the cataclysmic changes had to do with attacks on our trust in the structure of the generic terrestrial environment. This involves the ground plane, the existence of mutually disjunct solid bodies, optical properties like the opaqueness and diffuse scattering of material surfaces, and so forth. Impressionism [81] destroyed part of that by dissolving the picture of the environment into a chromatic, misty space. Cubism [82] merged the solid bodies with the background, and started their fragmentation. Pollock completely sacrificed solid bodies (Figure 20). The observer finally lost the ground under the feet. Meanwhile, movements like surrealism and dada attacked from the other side, so to speak, and destroyed the relations an observer silently expects to find in the generic terrestrial scene [83]. Figure 20. Left: Ingres (1780-1867) La source (begun 1820, completed 1856, Musée d’Orsay). Center: Picasso (1881-1973) Girl with mandolin (Fanny Telier) (1910, The Museum of Modern Art, New York). Right: Pollock (1912-1956) Echo No. 25 (1951, Pollock-Krasner Foundation / Artists Rights Society (ARS), New York). Compare the spatial structure. The figure in the Ingres is a solid form that stands in front of a background, there is space behind the body. The woman in the Picasso is easy enough to recognize as such, but is not solid, and seems to become part of the “background” (which therefore doubles as foreground). In the Pollock there is only a faint, fleeting and changing impression of objects and environment. The pictorial surface dominates over any classical “pictorial space.” 19 An analysis in terms of experimental phenomenology suggests a first rough inventory of the part of the space of images that might be open to the human visual observer. One criterion is whether microgenesis arrives at some fixed point after prolonged looking. Such fixed points appear to occur in one of the following three cases – a more or less uniform image; – a highly structured image, that is statistically uniform even in its small parts; – a “classical” scene. In the first case one sees nothing remarkable, whereas it is evident that this will never change, for want of structure. The blue sky is an instance, so are many modern minimalist paintings [84]. In the second case microgenesis “gives up” in face of complexity. The image is summarized as “texture”. The film grain in the sky of a fifties monochrome photograph is an example [85] (Figure 21). One doesn’t even try to “see anything” in such a sky, although the texture is noted. The third case is that of the nineteenth century still life, landscape, or genre painting. One simply sees what is there, and that is it. The proviso here is that images are rarely exhausted at one ontic level. The genre scene may well offer interesting “mystery” in the background, in the rendering of structure, and so forth. After all, no painter is going to paint all the leaves of grass, yet the image of a meadow can hardly be painted a uniform (dead) green. Figure 21. The effect of film grain. Such photographs work best at large size, when the grain is very evident. Notice that the grain, although an obvious texture, does not represent any property of the girl’s cheek, except - mirabile dictu - perfect smoothness. (Photo from http://purple-underground.blogspot.nl/2010/11/numero-goes-60s.html. The text reads “this editorial of NUMERO makes me think of the ones in the 1960’s TWEN magazine issues. It’s a perfect replication of the past. I love the high black and white contrast. very twiggy”.) NUMERO is an international fashion magazine (http://www.numero-magazine.com/). These three categories serve for a first parcellation of the space of images, a bit like the distinction between oceans and continents of the globe. Of course, the boundaries cannot be sharp. Given any image, it is always possible to construct a huge number of images that are essentially look-alikes. Thus, an image is not like a point, but like an open environment [86] in image space. Such open environments will be different for a glance, a good look, or under scrutiny. Under a glance the environment of look-alikes may well have a complicated structure, since the observer is likely to “miss” parts that would be easily “got” at another glance. Perhaps more interesting are the images for which microgenesis fails to immediately arrive at a (single) fixed point. One may distinguish (at least) – spontaneous jumps from one fixed point to another; – spontaneous fluctuations between a limited number of fixed points; – endless, chaotic fluctuations of visual presentation. In the first case the observer notices that visual awareness suddenly changes, whereas it is hard to regain the 20 previous presentation. An example is the well known “Dalmatian dog” picture *87+. At first blush it looks like a pattern of blotches. Once you’ve seen the dog, it will stubbornly stay. In the second case the presentations jump back and forth between a number of fairly obvious presentations. A well known case is Jastrow’s duck-rabbit *88+: you never see anything like a “duck-rabbit”, but either a duck or a rabbit. Moreover, these presentations spontaneously flip. The third case is perhaps the most interesting, both from an artistic, and from a scientific perspective. It is the case famously described by Leonardo da Vinci, in which the observer never stops to “hallucinate” in the presence of an image *89+. The first one who did an analysis in the style of experimental phenomenology on the topic was John Ruskin [90]. The effect was used in Western art mainly in informal drawings, or the background of “official” paintings, until the surrealists claimed it as one of their main devices. Leonardo writes: “look at walls splashed with a number of stains or stones of various mixed colors. If you have to invent some scene, you can see their resemblances (similitudine) to a number of landscapes, adorned in various ways with mountains, rivers, rocks, trees, plains, wide valleys and hills. Moreover, you can see various battles, the rapid actions of figures, strange expressions on faces, costumes, and an infinite number of things, which you can reduce to good, integrated form. This happens thus on walls and varicolored stones, as in the sound of bells, in whose pealing you can find every word and name you can imagine”. Of course, the same thing happens when you look at (or into) a painting. John Ruskin is special because he saw that one doesn’t need any ancient stained wall. Every vision suffices, if you only tune in to the presence of “mystery” in everything. Nothing is absolutely clear. You cannot count the grains of sand beneath your feet, nor the leaves on the tree before you. What the painter paints is not the leaves, but a leafy, “mysterious” texture [91]. Therein lies the art. There is a huge realm of the visual arts that exploits the pleasure experienced by observers due to Ruskin’s mystery. It has merely come bluntly to the surface in modern times. Like all pictorial structure, mystery occurs at all ontic levels. Much of surrealism occurred at the level of the represented entities. This is the level where René Magritte *92+ worked. In a sense, it is the least “visual” of these manifestations. The level of the “leafy texture” is the level of the smallest relevant constituents. It is purely visual, and interesting, although only mildly so. It is to be expected in virtually any serious painting (Magritte intentionally tried to avoid it). The most interesting levels from a conceptual point of view are the levels of the simple meaningful units and the salient Gestalts. Some of the more interesting work of Salvador Dali [93] plays on the latter level, but the former is perhaps the more interesting from the viewpoint of experimental phenomenology. Artists who address this level (for instance, Robert Pepperell [94], or Suzanna Unrein [95]) play on the sentiments described by Leonardo (Figure 22). Figure 22. Left: Suzanne Unrein Rapid East (2010; http://www.suzanneunrein.com). Right: Robert Pepperell Succulus (2005; http://www.robertpepperell.com). Notice how Unrein paints in a “post-neo-baroque”-style. She writes “I started with Rubens, Correggio and Raphael, then branched out to less likely combinations of Poussin and 21 Bougereau. Now it’s the animaliers of the 17th & 18th centuries, the boar hunts and dogfights. By combining the hounds from these genres with the figures from more epic scenes the dogs become a dysfunctional Greek chorus further confusing the summarizing of a scene. I am less interested in the narrative than the elements and forms that inspire the abstraction, and movement, with a larger range of color combinations. By combining figures from a variety of artists in a range of eras, I want to transport them from their original meaning into the contemporary domain and the challenge of newer interpretations”. Pepperell’s painting is ambiguous on purpose, he writes “… paintings and drawings are the result of intensive experimentation in materials and methods designed to evoke a very specific, though elusive, state of mind. The works induce a disrupted perceptual condition in which what we see cannot be matched with what we know. Instead of a recognisable depiction the viewer is presented with — what the art historian Dario Gamboni has called — a ‘potential image’, that is, a complex multiplicity of possible images, none of which ever finally resolves”. 22 3. Conclusion The topic is virtually boundless. I have only touched on a few conceptually interesting issues here, fully ignoring extensive fields of endeavor like architecture, photography, cinema, or mime. Moreover, I did not touch on the tangencies with music, poetry, and so forth. Each subtopic could easily be extended into a book, or a life of research. My main objective in this chapter has been to offer some general background for thought, and to show the way to potentially profitable openings for future research in the experimental phenomenology of the visual arts. 23 4. Notes (on the Web) Supplementary notes (Internet addresses as per January 2013). 1. Duchamp's Fountain is one of the landmark objects of twentieth century art. Virtually any book on “modern art” will have a section on it. A place to start is http://en.wikipedia.org/wiki/Fountain_%28Duchamp%29. On the person Marcel Duchamp see http://en.wikipedia.org/wiki/Marcel_Duchamp. 2. Objet trouvé is French for “found object”. It has become a standard term in art circles. In English one more often uses “ready made”. A place to start is http://en.wikipedia.org/wiki/Found_object. 3. “Intentionality” is a philosophic term meaning something akin to “pointing to something (usually something in the world)”. For instance a thought is necessarily about something, you cannot have a thought that is about nothing, although you may have thoughts about NOTHING. The term is usually traced to the teachings of Franz Brentano (see also Albertazzi, this volume, chapter 2). Notice that “intention” has nothing to do with the intentions of anybody. A starting point is http://en.wikipedia.org/wiki/Intentionality. On Franz Brentano see http://en.wikipedia.org/wiki/Franz_Brentano. 4. Fyodor Mikhailovich Dostoyevsky (1821-1881, was a Russian writer of novels, short stories and essays. See http://en.wikipedia.org/wiki/Fyodor_Dostoyevsky. The Brothers Karamazov is his final novel. See http://en.wikipedia.org/wiki/The_Brothers_Karamazov. 5. In our times “conceptual art” is almost synonymous with art period. This is a fact, whatever thoughts one may have on it. A starting point is http://en.wikipedia.org/wiki/Conceptual_art. The number of popular books on the topic approaches infinity. 6. Raphael is the short name of Raffaello Sanzio da Urbino (1483-1520). Raphael was one of the best known Italian painters and architects of the High Renaissance. There are many books on the man and his work, a convenient starting point is http://en.wikipedia.org/wiki/Raphael. Raphael’s Sistine Madonna (La Madonna di San Sisto, 1513/4) is the last painting he personally finished. It was completed ca. 1513-1514, as a commissioned altarpiece. See http://en.wikipedia.org/wiki/Sistine_Madonna. 7. Picasso's Bull's head is a work the artist did during WW-II. It is an amazing work, that could be seen as a simple child's play, or (equally well) as an extremely sophisticated creation. At the time, the work was not particularly appreciated by the public, it was removed from an exhibition for that reason. See http://en.wikipedia.org/wiki/Bull%27s_Head. 8. I use Piero Manzoni’s Merda d’artista to illustrate what I think of “conceptual art”. Maybe you (the reader) thinks it is a work of genius. That is fine, as long as my point that conceptual art is not visual art comes across. (Who cares for visual art anyway? It is the concept that counts!) My (mis-)use of Manzoni is perhaps unfair. Read up on this on http://en.wikipedia.org/wiki/Artist%27s_shit and http://en.wikipedia.org/wiki/Piero_Manzoni. 9. Maurice Denis (1870-1943) was a French painter, a member of the Symbolist and Les Nabis movements. He was something of a theorist too, and did quite a bit of writing. On his life see http://en.wikipedia.org/wiki/Maurice_Denis. The quotation is from a Symbolist Manifesto of 1890.

See J.Koenderink, A.J.van Doorn, and J.Wagemans, Depth, i-Perception 2(6), 541-564. 24 11. Paul Jackson Pollock (1912-1956), known as Jackson Pollock, was an influential American painter and a major figure in the abstract expressionist movement. He became extremely influential. Jackson Pollock was best known for his unique drip painting, and was sometimes known as “Jack the Dripper”. See http://en.wikipedia.org/wiki/Jackson_Pollock. (In case you fail to get the nickname see http://en.wikipedia.org/wiki/Jack_the_Ripper.) 12. The Holy Face of Jesus is one of the acheiropoieta relating to Christ. These have been reported throughout the centuries. Especially devotions to the face of Jesus have been practiced throughout the ages. Devotions to the Holy Face were approved by Pope Leo XIII in 1895 and Pope Pius XII in 1958. The shroud of Turin is the best known example. See http://en.wikipedia.org/wiki/Holy_Face_of_Jesus. On the face in the toilet door see http://www.telegraph.co.uk/news/religion/6373674/Jesuss-face spotted-on-the-toilet-door-in-Ikea-Glasgow.html. Another recent example is the face in a tree stump at Belfast cemetery (http://www.belfasttelegraph.co.uk/news/local-national/northern-ireland/face-of-jesus-christ-appears-on-tre e-stump-at-belfast-cemetery-16195735.html), drawing crowds of visitors. 13. Mark Tansey (born 1949) is an American painter born in San Jose, California. The Innocent Eye Test dates from 1981. According to Tansey ( quoted in Mark Tansey: Visions and Revisions, by Arthur C. Danto), see http://www.101bananas.com/art/innocent.html: “I think of the painted picture as an embodiment of the very problem that we face with the notion ‘reality’. The problem or question is, which reality? In a painted picture, is it the depicted reality, or the reality of the picture plane, or the multidimensional reality the artist and viewer exist in? That all three are involved points to the fact that pictures are inherently problematic. This problem is not one that can or ought to be eradicated by reductionist or purist solutions. We know that to successfully achieve the real is to destroy the medium; there is more to be achieved by using it than through its destruction”. 14. Roman marble copies of original Greek bronzes: a well known example is the famous Discobolus. See http://en.wikipedia.org/wiki/Discobolus. The Greek original was completed towards the end of the Severe period, circa 460-450bc, but the original Greek bronze is lost. However, there exist numerous Roman copies, including full-scale ones in marble. The first one found (in 1781) is the Palombara Discobolus. It was famously bought by Adolf Hitler in 1937 (put in the Munich Glyptothek), but was returned to Rome in 1948. 15. Edmund Husserl has a notion of “double-intentionality” that is quite different from my meaning here. In order to avoid problems I will speak of a “double-sided intentionality” associated with works of art. In Husserl's view the Langsintentionalität runs along protention and retention in the living present, whereas the Querintentionalität runs from the living-present to the object of which consciousness is aware. See http://www.iep.utm.edu/phe-time/#SH1e. On Husserl (Edmund Gustav Albrecht Husserl, 1859 -1938) see http://en.wikipedia.org/wiki/Edmund_Husserl. 16. Hermeneutics is (roughly speaking) the art and science of text interpretation. See http://en.wikipedia.org/wiki/Hermeneutics. 17. Francis George Steiner (born 1929), is an influential European-born American literary critic, essayist, philosopher, novelist, translator, and educator. See http://en.wikipedia.org/wiki/George_Steiner. Here I am mainly referring to his influential book After Babel (1975), on translation, for which see http://en.wikipedia.org/wiki/After_Babel. 18. Classic authors on the topic are Rudolf Arnheim (1904-2007; see http://en.wikipedia.org/wiki/Rudolf_Arnheim), and José Ortegay Gasset (1883-1955; see http://plato.stanford.edu/entries/gasset/). 19. Roman Ingarden’s ontological thoughts are particularly relevant here. See 25 http://plato.stanford.edu/entries/ingarden/. 20.

Sir Peter Paul Rubens (1577-1640), was a Flemish Baroque painter, and a proponent of an extravagant Baroque style that emphasized movement, color, and sensuality. See http://en.wikipedia.org/wiki/Peter_Paul_Rubens. 23. Alessandro di Mariano di Vanni Filipepi, better known as Sandro Botticelli (1445-1510) was an Italian painter of the Early Renaissance.
