1 Steven M. Ortiz and Samuel R. Wolff GEZER 2014 REPORT (License No. G52-2014) Figure 1: Aerial (north at top) The Tel Gezer Excavation project is a long-term joint project addressing chronological reevaluations, ethnic and social boundaries, and state formation in the southern Levant. To date, the project has conducted seven summer field seasons. The seventh season of the renewed excavation of Tel Gezer took place between 23 June and 18 July 2014. The excavations were directed by Dr. Steven M. Ortiz of the Tandy Institute for Archaeology at Southwestern Baptist Theological Seminary and Dr. Sam Wolff of the Israel Antiquities Authority. The excavations were sponsored by the Tandy Institute for Archaeology at Southwestern Baptist Theological Seminary. The project also received financial support by a consortium of institutions: Andrews University (associate), Ashland Theological Seminary, Clear Creek Bible College, Emmaus Bible College, 2 Lycoming College, Marian Eakins Archaeological Museum, and Lancaster Bible College and Graduate School. The excavations were carried out within the Tel Gezer National Park and benefit from the cooperation of the National Parks Authority. The excavation project also received support from Kibbutz Gezer and the Karmei Yosef Community Association. The Project is affiliated with the American Schools of Oriental Research. Figure 2: 2014 Participants INTRODUCTION Just over 55 participants from the consortium schools as well as other students and volunteers from several countries (U.S., Israel, Palestinian Authority) participated in the project. The Tel Gezer expedition included: Gary Arbino (senior field archaeologist), Cameron Coyle (field archaeologist), Beth Ortiz (camp manager) Lin Pruitt (Material Culture Manager and Educational Coordinator), Julie Harrison (Pottery Lab Manager), and Shachar Stefanski, Kibbutz Hulda. Area supervisors were: M. Barbosa, J. Chatfield, J. Jewell, R. DeWitt-Knauth, K. Miller, G. Nagagreh, and A. Wegman; Assistant Area Supervisors were: Sirius Cheng, Steve Sanchez, Brian Stachowski, Philip Webb, and 3 Charles Wilson; zooarchaeology: L. Horowitz; architect/draftsman: J. Rosenberg, computer database designer: D. Pride. The research goal of the project is to investigate state formation and regional boundaries in the northern Shephelah by investigating the Iron Age cultural horizon at Tel Gezer. These broad research trends in Iron Age archaeology are being addressed by current research projects in the Shephelah and Southern Coastal Plain; specifically ethnic and political boundaries in the Judean Hills and the Philistine coastal plain. FIELD STRATEGY Work continued in the two major fields (E and W). Field E encompasses an area west of the Iron Age Gate Complex (Field III of the HUC excavations). The goals of this area are to investigate the urbanization process of the Iron Age City. Field W is located west of Field E. The goal of this field is to 1) investigate the several Iron Age occupation horizons of the tell, and 2) provide data from Iron Age domestic quarters to compare and contrast with the public buildings to the southeast in Field E. It also includes a northsouth sondage to investigate the relationship between the Iron Age wall and the “outer” wall. Field E was formerly called Field A. This field includes an east-west section of squares from the Iron Age gate to the west exposing the city fortification system and its relation to building activity built up against the city wall and an area north of the fortification wall where a series of large public buildings are located. Currently in Field E we have three strata that have been defined and are exposed. In the 2014 season, our goals were twofold, 1) remove unexcavated walls and surfaces of 9th and 8th century strata in the field, 2) start to excavate the 10th century stratum, particularly in the eastern part of the field to connect with the previous work of the HUC excavations. The 2014 goals for Field W were to continue excavations to the north, excavate expediently to the Late Bronze Age strata, and continue exploring the fortification systems in the sondage and searching for the wall line of the outer wall. 4 GOALS AND ISSUES FOR THE 2014 SEASON 1. One of the questions in Field W is how many strata and/or phases of the Iron Age I are in this area of the tel. It is clear that we have more than one phase based on surfaces, yet evidence of only one major destruction was discerned. One of the difficulties is the exposure of our Iron Age I destruction is limited to rooms adjacent to the city wall and these rooms only produced complete storejars that have a long life-span. They are similar to other storejars that are dated to the 11th and early 10th centuries BCE. In addition, Field W is located in the slope of the western hill where contemporary occupation levels have decreasing elevation levels from west to east. 2. The above question will be addressed by expanding the northern squares of Field W as well as to the east to get a more complete plan of the 10th century stratum and the Iron Age I plan. Perhaps beneath the 10th century plan will be undisturbed strata of the Iron Age I. 3. The continued excavation in Field E to the 10th century stratum in order to get a complete plan of the urbanization process west of the Iron Age Gate Complex. 4. The above goal can only be accomplished with the dismantling of the tripartite buildings of Stratum 6. This project was partially started at the beginning of the 2013 season. The work in both fields progressed slowly due to the following factors: 1) reinterpretation of the Iron Age II retention wall system as a reused Iron Age I city wall, 2) difficult stratigraphy of the various Iron Age walls in Field W necessitated slow and careful removal of various walls. In Field E, it was assumed that we would quickly be on our Stratum 7 (9th century BCE) levels immediately. In reality, the 8th century BCE tripartite Building A had very extensive foundations as well as disruption of this area by several Hellenistic structures (Wall 61023, Kilns 41010 and 61058) as well as pits and earlier excavations by Macalister. The discernment of two building phases of the 8th century BCE buildings (e.g. Stratum 6) also slowed the removal of the Stratum 6 building as we spent time documenting and excavating the rebuilding of Building A. The 9th century was only discerned in two squares with the possible remnants of wall lines in other squares (W61040 and W61043). 5 OVERVIEW— 2014 RESULTS Major results of the 2014 season were: 1. Phase 6: In areas A4/5 remnants of a building with a thick heavy plaster floor was excavated. This is either another building or the northern wall of Administrative Building B excavated in previous seasons. 2. Phase 7 (9th c. BCE): The Phase 7 destruction was revealed and excavated within a room unit north of previous excavations of this destruction (e.g. Square C8 and C7). This destruction was located in Area C6. 3. Phase 7 northern enclosing wall line. The northern wall line of the various units excavated in previous seasons was also established. It is now confirmed that the Phase 7 occupation reused walls of Phase 8 (10th c) [Wall 61059]. It was also confirmed that Wall 31041 dates to this phase. 4. Phase 8 (10th c. BCE). About 200 square meters were exposed of Phase 8 in Field E. This wide exposure united elements of the 1984 HUC excavations (e.g. Basin and walls). In addition we were able to correct the original schematic plan of “Palace 10000” of the HUC excavations. 5. We have a tentative plan of the 10th c Building Complex directly to the west of Palace 10000. This complex consists of an open courtyard abutting the north face of the casemate wall with two rooms on the north end of this courtyard. Massive ashlar stones were also excavated (exposed in 1984 HUC excavations and our 2012 excavation season). It is now clear that what we thought was just rock tumble is actually the north-south wall line between Palace 10000 and our Building Complex. 6. We have an overall plan developing of Phase 8. We have defined five major building complexes (including HUC Palace 10,000). 7. In addition, we have defined at least two phases of Phase 8. Our interpretation can only be tentative as to whether this represents a new stratum or if it is just a rebuild of the same stratum. These two phases were only found in Building 1 in Field W. The second phase of this building consists of a more robust rebuild (e.g. walls with two courses instead of one). This is a similar location to a second phase of our Phase 6 (8th century BCE). 1) Perhaps Field W allowed for a better discernment of these phases, 2) this is where the slope is steep (buildings are 6 constructed on the eastern slope of the western hill) and there needed to be rebuilds due to stability or erosion), 3) preservation of this phase was due to its location on the slope and did not get removed by later building activities and/or excavations (e.g. Macalister). 8. We have added to the plan of our Iron Age I Strata. We have nearly 500 square meters of horizontal exposure. We can discern five units and a courtyard or street. In four of these units we have at least two complete storejars in each building unit. In the fifth unit we have the remains of a tabun. 9. The addition of a wall stub (W 72038) was exposed in Area A8. It is in line with the northern wall line of the Late Bronze Age building of Stratum 11. If this is the continuation of the wall line, then the building is at least 20 m in length. 7 Tel Gezer Master Stratigraphic Chart 2006-2014 Preliminary Strata Field E (formerly A) Field W (formerly A-sondage and B) 1 Topsoil, Modern Excavation Dumps HUC dump Trenches, rock piles HUC Dump (V, W, Y) 2 Bergheim Estate, Abu Shusheh, Macalister Backfill Backfill Hellenistic Wall corner, pottery kilns, reused IA walls(?)

This was stratigraphically below the Iron Age glacis in Field W. In 2013 with the attempted excavation and removal of Iron Age walls, the continuation of this LB destruction layer was discovered. This is isolated on the southern edge of Field W, south of the Iron Age I wall. This allowed for a more thorough investigation of the Late Bronze Age destruction. Several vessels (cooking pot, krater, store jars) were found in the destruction; as well as a scarab of Amenhotep III and three cylinder seals. In previous seasons, elements of this LB destruction layer were also found in probes beneath the Iron Age glacis. Several fragments of Cypriot and Mycenaean pottery were found in these exposures. With this major exposure, all components of this LB destruction are able to be coalesced and a date to the 14th c. BCE can be established. This 14th c. BCE destruction matches other LB IIB destructions in the region (e.g. Beth Shemesh, Timnah- Batash, Azekah, and Jaffa). Fig 3: Late Bronze Age (Stratum 11) [in green] Our 2014 goals were to excavate the squares to the north to get a complete Iron Age I plan of the field, not anticipating to reveal anymore of our Late Bronze Age stratum. In 9 the process of excavating our Iron Age I strata (Strata 9 and 10), we found another part of the Late Bronze Age Building. This was added to our plan (Fig 4). This wall line was found in Area A8. Figs. 4: Late Bronze Age Building (Stratum 11) This limited exposure has revealed more components of a pillared building or complex of rooms. While we have a tentative plan of the building or complex, the function of this building is still unclear. The large pillar base found in previous seasons allows us to postulate that this was a public building or the home of a prominent resident. Some of the finds included a roof roller and large grinders. Previous publications noted that the Late Bronze Age Stratum is found on the edge of the slope with the southern extent eroded down the slope. It was built directly on the Middle Bronze Age glacis. Based on this data, we proposed that there was no LB city wall (at least in this area) and that the LB did not reuse the MB fortifications. Excavations this season continued to support this pattern. Sometime in the Iron Age I, a city wall was built directly over the Late Bronze Age destruction and occupation. An Iron Age II glacis was built over the Iron Age I wall and provides evidence for the extent of the slope during this period. While our investigations into the Late Bronze Age is still in its initial stages, 10 perhaps this destruction is indicative of the unrest between the Canaanite city-states as reflected in the Amarna correspondence. IRON AGE I WALL AND DESTRUCTION Last season we exposed an Iron Age I city wall beneath our Iron Age II Wall. In addition we started to discern various units. The plan of the Iron Age I stratum was a major goal this season in Field W. Part of the issue is the topography of Field W as this field sits on the eastern slope of the western hill; and 2) walls of Iron Age II (e.g. Stratum 7 and 8) remained from the 2013 season, thus separating stratigraphic connections between building components in Field W and E. A senior staff member (Arbino) postulated that some of the walls in Field E that were tentatively attributed to Stratum 7 actually belong to Stratum 9. Hence one of the major goals was to remove all later stratigraphic elements and connect the walls between both fields to get a complete stratigraphic plan of the Iron age I city. While this slowed down the progress, the focus on the tight stratigraphy as walls and balks were removed proved Arbino’s stratigraphic postulates. We now have an accurate spatial analysis of the various building units of our Stratum 9 and further defined the layout of the city (see Fig. 5 and G. Arbino, 2014 Field W Report). Each of these building units is constructed of a single course of unhewn stone. Those units against the city wall, had their southern wall line incorporated into the city wall (Units A, B, and C). Some of the walls we thought were Iron Age II we now have to redate to the Iron Age I City (W51117, W51009, W51119). We now have to change the plan of our 9th century city. We knew this terracing of the Iron Age I city existed from last season, as each unit (where we found complete vessels-mostly store jars) sloped in elevation from the NW to the SE. Finds from this Iron Age I city include: Philistine pottery and an Ashdoda Head (Philistine Figurine of a goddess). These finds hint at the Philistine and coastal influence on this Canaanite city. In addition we have a spearhead, arrowheads, and balistae. 11 Figure 5: Iron Age I (Stratum 9-10) We found several restorable storejars within these units. Unit A (yellow) consists of three rooms. Its southern wall is integrated into the city wall. The western end of the building is unexcavated. The excavated area of this unit is 10 x 8 m. Two of the rooms each contained a complete storejar. To the east of this unit is Unit B, which appears to be a cellar or basement as the surface level was nearly ½ meter lower. This Unit is a single rectangular room, 3 x 6 m. Unit B had nearly half a meter of an ashy fill. Within this unit were two storage jars up against the northern wall. In the middle of the room was a multihandled krater. Within the ashy destruction debris were several mushroom-shaped clay stoppers. One of these stoppers contained the stamp seal which according to Stefan 12 Munger, belongs to a type referred as Early Iron Age Mass-produced seals, which date to the Iron Age I or slightly later. Munger has proposed that these seals reflect a small campaign by Siamun. Unit C, possibly connected with the subterranean Unit B because their southern walls were built as a single wall-line, which is also the line of the city-wall. Unit C, 8 x 4 m, contains two rooms. Each room contained a storage jar. To the north of Unit C was one of the largest units, possibly 12 x 10 m. This unit contained a tabun with a white plastered or phytolith surface. To the west of this unit was Unit D. This unit, 10 x 8 m, contained several rooms. It also had two complete storage jars, iron implement, bronze spear butt, and a fragment of a unique vessel. Unit E was highly disturbed by later activity; only a beaten earth surface and tabun were discerned. This unit is about 12 x 12 m in area. All of these units were constructed with singe row walls constructed of unhewn stones. The exception are Units A-C where the southern wall was the city wall. These were domestic units. None of these units with the exception of Unit E were the typical courtyard house (Gilboa, Sharon, and Zorn, 2014). The HUC excavations uncovered two Iron Age I courtyard houses on the acropolis (Field VI). When the Field W Iron Age domestic units are compared to the two on the acropolis, it is clear that these are of a poorer quality. It is possible that the Iron Age Courtyard houses on the acropolis were elite compared to this quarter found next to the southern city wall. The Iron Age I destruction and city wall were a surprise. While we knew that the HUC excavations revealed Iron Age I occupation, it was only found in Field VI on the acropolis, with minor ceramic evidence on the southern end of the tel. We now have evidence for at least two domestic quarters of the Iron Age City. Unlike the courtyard houses on the acropolis, we found minimal Philistine bichrome pottery in the fills and debris of the Iron Age I. IRON AGE II This season we finally exposed architectural features and clean, undisturbed occupation associated with the earliest phase of the six-chambered gate. This is our Stratum 8 (HUC VIII). In previous seasons, not much has been exposed of the Iron Age IIA occupation 13 (10th c. BCE). In Field W, only the remnants of a cobbled surface and the outlines of buildings were left by Macalister. Earlier excavations of HUC and Dever have exposed the 10th century structures near the gate (his Palace 10000). We have now defined at least Figure 6: Stratum 8A (phase destroyed by Shishak) five architectural units of the Stratum 8 Iron Age city plan. Four of these units are built against the north face of the casemate wall and are west of the six-chambered gate (see Fig 6). Three of these units (I-III) were already excavated in previous seasons. Unit II has evidence of two phases (see below). Unit V was also previously excavated by HUC in 1984. Unit IV was partially excavated this season (see below). Field W: Stratum 8 In the process of removing walls of later phases to obtain a complete stratigraphic plan of the Iron Age I plan in Field W (see Fig. 5), evidence of rebuilds and building alterations were discerned. Most of the surfaces have been removed or destroyed by later Hellenistic building activity and Macalister excavations; nevertheless, it became apparent that there is evidence of another earlier phase (see Fig 7). It appears that Stratum 8 reused wall 14 lines of the Iron Age I (e.g. Stratum 9 and 10). These walls continued to be constructed as single row unhewn stone foundations with a mudbrick superstructure. Later, one of the units was remodeled and used stone walls with two rows of unhewn pillars (see walls 21074 and 11101, 11100, and 31016 in Figure 6 [located in the west in Areas Y7 and Z 7/8]). Figure 7: Stratum 8B Field E: Stratum 8A In regards to Stratum 8, we had our most productive season this past summer. One of our major goals was to excavate components of Stratum 8 in Field E. We now have a 10th century BCE city plan emerging (see Fig. 6). We have tentatively identified two complexes. To the east are the remnants of the HUC excavations; this is what Dever called Palace 10000 and Soldier’s Barracks (Unit V). To the west of this complex is a second set of structures. We have isolated a courtyard abutting the casemate wall with two rooms. These complexes are built with large rough field stones. What is unique is that the corner of the buildings have ashlar stones. There is a major wall separating these two complexes built mostly of ashlar blocks. These were tipped over from the east to the 15 west. We are tentatively associating this with the Shishak destruction that was postulated by the HUC excavations. This wall was already identified by Dever.1 The rooms are not fully excavated; we are about 20 cm to ½ a meter above the surface levels. This past season, we uncovered a game board. This game board features the standard layout of the Game of Twenty Squares. This board features three parallel rows of squares, laid out in groups of four, twelve, and four, with rosettes marking five of the twenty squares. The quality of the game board suggests its identification as a prestige object, and perhaps indicates an elite usage of Room A. Hopefully, the completed excavation of this room in the 2015 season will provide additional data to consider in this interpretation. Retrieved from these rooms were olive pits, pounding stones, gaming pieces (3), a spindle whorl, slings stones, and projectile points. A number of large bones were recovered, including a well-preserved (sheep?) horn, and bovine mandible from two different animals. To the south of these rooms was a courtyard with a tabun, vat, post holes, remnants of charred wooden beams, plastered surfaces. Small finds from the courtyard found in close proximity to this installation include an Egyptian-style faience Bastet bead (B71490) and fragments of a bull figurine (B71457) with a unique circular appliqué on the forehead. IRON AGE II: 9TH CENTURY Our Stratum 7 occupation was excavated in previous seasons. We found four principle units with evidence for destruction in several of the rooms. We only have a plan for one of the three complexes. Each unit averaged about 10 x 10 m. in area with 8-10 rooms. Most of the walls were constructed of a single row of stones. We assumed that most of the remnants of the Stratum 7 destruction were excavated. We were surprised to find that a complete room (pillared building) was still preserved. Leading to this assumption was the line of Stratum 8 walls exposed at the end of last season. It is now clear that Stratum 7 reused some of these Stratum 8 walls in their phase. While the excavation of this William G. Dever, “Gezer Revisited: New Excavations of the Solomonic and Assyrian Period Defenses.” The Biblical Archaeologist 47 (1984): 216. 1 16 destruction hindered the goal to expose our Stratum 8 city plan, we were pleased to add a robust ceramic database and distribution of finds to Unit B. Figure 8: Stratum 7 (9th century BCE) In what is typically an administrative quarter of an Iron Age city, these units appear to be domestic. It is clear that Stratum 7 (9th c.) reused the earlier fortifications and casemate wall line. The 10th c. monumental architecture (e.g. pillars, ashlars, walls) that is found in Stratum 8 is missing from this stratum as the area adjacent to the city gate became a domestic quarter. CONCLUSION Our results can be highlighted by the definition and refinement of three major strata. First off, the Iron Age I city in Field W is starting to come into focus. The removal of the Iron Age II wall and the eastern expansion of Field W has allowed for a broad exposure. The project has isolated a domestic quarter with at least five building complexes. This quarter was built up against, and the southern rooms formed the perimeter city wall. These buildings are constructed of single row walls. These domestic units are very different than the buildings found on the acropolis (Field VI) that were excavated by the 17 HUC excavations. When the results of the two excavations are coalesced, it appears that Gezer had two domestic quarters, 1) on the acropolis are large residencies while 2) on the southern slope of the western hill are poorer constructed buildings. This stratum was destroyed sometime during the Iron Age I/II transition. The dating is based on storage jars and a stopper with a Siamun seal. A second stratum was the excavation of a pillared room of Stratum 7 (9th century BCE). This room had a thick layer of destruction with several pottery vessels. This destruction debris was excavated in previous seasons. We are now able to complete the architectural plan of the city of Stratum 7. One of the main goals this season was to start to excavate Stratum 8 (10th c BCE). One of the goals was to connect the architectural components in the Tandy excavation area (e.g. Field E) with Dever’s ‘Palace 10,000’ and his ‘Soldier Barracks.’ This stratum consisted of large boulders from the superstructure of buildings. Naturally the excavation and removal of these stones slowed down our progress. We removed most of the stones, with the exception of several ashlar blocks. The surfaces were left unexcavated in order to systematically excavated the rooms. We initially postulated that the 10th c. BCE city contained a belt of administrative bldgs.; just like what we had in the 8th century BCE. The 9th century (excavated 2 seasons ago) had domestic units built up against the casemate. Based on the work this season, we now know that the 9th century domestic units originate from the 10th century and were reused in the 9th century. We have to rethink our Iron Age IIA (e.g. 10th c. BCE/Solomon) city planning and note that the administrative buildings were isolated west of the gate up to our excavation area (e.g. “Solomon’s bathtub”). We found evidence of massive ashlar construction up to our excavation area; this ashlar wall was tipped over. The building north of the courtyard (Areas D/E 6) was also probably administrative or elite building. We have two rooms that open out into the courtyard to the south. One room contained the ivory game inlay and the other room had a bin with bones of calves. DATING We are now accumulating four major strata with pottery. 1) We have an 8th century destruction (Four Room House from previous seasons), 18 2) a more robust 9th century destruction (2011 season + Philip’s square), 3) some 10th century (Jerry and Brian’s squares)—with the assumption that next year we will uncover pottery in the two rooms; 4) and an Iron Age I destruction (adding the pottery that we excavated this season with pottery from previous seasons). This is going to provide an excellent ceramic database for this region.
