Introduction
The Late Bronze Age (c. 1600–1100 BC) is a period of major political developments across Anatolia and the Aegean. A growing body of scholarship is transforming our understanding of central Anatolia and the southern Aegean during this period, but the region between them—western Anatolia—has received less attention. Research in this region has primarily focused on historical evidence for the configurations of Arzawa, an enigmatic geographic and political entity that existed in various forms for more than 200 years. Arzawa appears in several Hittite records as a confederacy of kingdoms in conflict with Hatti (home of the Hittites in central Anatolia) that notably invaded a territory subject to the empire in the early to mid-fourteenth century BC (Bryce Reference Bryce2005: 146–57). The Arzawa confederacy was ultimately quashed and split into vassal kingdoms under the Hittite king Mursili II (Beckman Reference Beckman1999: 63–93), after which one of these kingdoms, Mira, re-emerged as a major power in the thirteenth century BC (Bryce Reference Bryce2005: 306–8).
While ceramic studies are providing insights into regionalism and exchange across western Anatolia (e.g. Pavúk & Horejs Reference Pavúk and Horejs2018), the limited number of well-excavated settlements means that evidence for social, political and economic structures is limited. Systems of agricultural production, in particular, are poorly understood, with archaeobotanical reports available for only four sites: Troy (Riehl Reference Riehl1999); Kaymakçı (Shin et al. Reference Shin, Marston, Luke, Roosevelt and Riehl2021); Beycesultan (Helbaek Reference Helbaek1961); and Perge (Kroll Reference Kroll, Martini and Eschbach2017). This represents a crucial gap in research given the importance of farming in understanding prehistoric lifeways and the major roles that the production and mobilisation of agricultural resources played in the neighbouring political economies of Late Bronze Age central Anatolia and the Aegean (Jakar Reference Jakar2000: 266; Halstead Reference Halstead, Voutsaki and Killen2001).
Here, we begin to address this lacuna through the analysis of archaeobotanical remains recovered from the citadel of Çine-Tepecik, western Anatolia. This first in-depth analysis of plant remains from central storage contexts in the region provides unique insights into the role of farming within the political economy of the lands of Arzawa. In addition, we assess the range of crops cultivated at the site and the implications of this diversity for the existence of a regional suite of agricultural practices. We also assess the significance of the presence of broomcorn millet for our understanding of the spread of the species across Anatolia.
Çine-Tepecik
Çine-Tepecik lies at the centre of a fertile alluvial plain, south of the Büyük Menderes River (ancient Meander) in western Anatolia (Figure 1). Occupation of the site spanned from the Chalcolithic (c. 5450 BC) until the end of the Late Bronze Age (Günel Reference Günel, Weeden and Ullman2017). During the Late Bronze Age the site included a citadel surrounded by a robust fortification wall (Figure 2). Within this, a storage magazine, measuring 16.5 × 4.5m, contained large numbers of pithos vessels (storage containers), both complete and fragmented (Günel Reference Günel, Weeden and Ullman2017). Two large pithoi were also built into a stone-paved platform constructed next to a section of the fortification system that has since been destroyed (Figures 2 & 3). Imported and locally produced Mycenaean pottery date the use of these structures to the Late Helladic III B2 and III C (c. 1350/1300–1240/1100 BC; Günel Reference Günel, Weeden and Ullman2017), while radiocarbon dates obtained from charred wheat found among the pithos fragments (sample 7, see below) date to 1415–1125 BC (Günel Reference Günel, Henry and Belgin-Henry2020: 36). Two seal impressions were recovered from the magazine, one identifying the owner of the seal as a Hittite prince called ‘Tamipiya’ and the other bearing a name similar in form to Tarkasnawa, the thirteenth-century king of Mira (Günel & Herbodt Reference Günel and Herbordt2010, Reference Günel and Herbordt2014). These finds align Çine-Tepecik with the vassal kingdom of Mira, thought to have had its capital at Ephesus and to have spanned the Küçük and Büyük Menderes River valleys (Hawkins Reference Hawkins1998: 23–25, 31).
The presence of large pithoi and a dedicated storage magazine in the excavated area of the citadel attest to concerns with the storage of farming products within institutional contexts, likely under some form of central authority. Archaeobotanical remains recovered from these contexts therefore provide the rare opportunity to investigate the political economy of farming within a Late Bronze Age settlement in western Anatolia.
Methods
Detailed methods for the recovery and analysis of archaeobotanical remains are reported in the online supplementary material (OSM). Sediment was sampled from visibly burnt contexts and from inside pithoi and other ceramic vessels (i.e. using a ‘judgemental’ sampling strategy; Figueiral & Willcox Reference Figueiral, Willcox, Jones and Rowe1999). In some cases, archaeobotanical remains were hand-picked from sediment during excavation. Soil samples were processed by water flotation using an Ankara-type flotation tank (French Reference French1971). Remains that floated were collected in a 300μm mesh and the remaining material was retained in a 1mm mesh. Archaeobotanical samples were assessed using a low-power stereo microscope (7–45× magnification). Plant taxa were identified through comparison with modern seeds from a personal reference collection and published sources (e.g. Nesbitt Reference Nesbitt2017). Thirty Late Bronze Age sediment samples were found to contain crop remains and were included in this study.
Archaeobotanical results
Crops and economic taxa
A broad range of potential crop taxa were identified (Figure 4; Table 1). Shown in Table 1, free-threshing wheat (Triticum turgidum/durum) and hulled barley (Hordeum vulgare L.) dominated the assemblage by counts. Hulled barley was by far the most ubiquitous taxa, present in 21 of 30 samples. Cereal species recovered in smaller quantities from fewer samples were broomcorn millet (Panicum miliaceum L.), emmer wheat (Triticum turgidum L. subsp. dicoccum (Schrank) Thell.) and einkorn wheat (Triticum monococcum L. subsp. monococcum).
Pulses were relatively poorly represented in the assemblage. A significant number of seeds were also heavily fragmented, preventing further taxonomic identification. The pulse assemblage was dominated by lentil (Lens culinaris Medik. subsp. culinaris) and bitter vetch (Vicia ervilia (L.) Willd.). Small quantities of flax (Linum usitatissimum L.), grape (Vitis sp.) and fig (Ficus carica L.) seeds were also recovered.
Compositional and contextual analysis
While the overall density of archaeobotanical remains within the 30 sediment samples was low (approximately one item per litre), 10 samples were rich enough to warrant further analysis. Figure 5 shows the proportions of different crops and arable weed/wild taxa of different size categories within samples that contained 20 or more crop seeds. The contexts from which the samples were recovered are listed in Table 2 and their locations shown in Figure 6.
The size of weed/wild seeds can be used to make basic inferences about the processes by which they became deposited in the archaeological record. By sampling the residues of free-threshing cereal processing conducted by modern farmers on the island of Amorgos, Greece, Jones (Reference Jones1983) found that the by-products of various processing stages (e.g. winnowing and sieving) tended to be dominated by small-seeded arable weeds. Large-seeded weeds were able to pass through processing and remained abundant contaminants of semi-clean grain. These seeds are often removed by hand piecemeal prior to consumption and are therefore found in semi-clean crop stores (Hillman Reference Hillman1984: 132–33). Seeds of weed/wild taxa may also enter the archaeological record within animal dung burnt as fuel. Experimental work conducted by Wallace and Charles (Reference Wallace and Charles2013) found a bias towards the presence of small and hard-seeded taxa within animal dung due to their greater likelihood of surviving digestion.
Figure 5 shows that samples 3–6, 9 and 10 contained significant quantities of small-seeded weed/wild taxa (such as small grasses and legumes, see Table S1) and are therefore likely to contain material derived from crop processing waste and/or animal dung burnt as fuel. This suggests that they are unlikely to represent the original stored contents of the pithoi and rather derive from refuse material disposed of in fires and then dumped in the vessels after they fell out of use. While no dung fragments were visible, dung itself may not survive charring or may become highly fragmented, hindering its recognition in the archaeological record (Charles Reference Charles1998). In contrast, samples that contained near pure concentrations of free-threshing wheat or barley (samples 1, 2, 7 and 8) contained no weed/wild seeds or were dominated by those over 1mm in size (such as darnel ryegrass (Lolium temulentum) type). This suggests that these samples derive from semi-clean crop stores. A caveat to this interpretation, in the case of samples 2 and 7, is that recovery by hand during excavation, as opposed to processing by water flotation, may have influenced sample composition. It is possible that hand recovery created a bias against small seeds, mimicking the composition of semi-clean crop stores, but this caveat does not apply to the remaining near pure samples, suggesting sampling methods are unlikely to be responsible for the overall patterning within the dataset.
While recovered from pithoi and likely derived from semi-clean crop stores, a lack of evidence for burning in situ suggests that samples 1 and 2 may also represent secondary deposits of refuse rather than the original stored contents of the vessels. Samples 7 and 8 were recovered from burnt sediment among pithos fragments that may represent in situ destruction and burning, but this cannot be said with certainty. Despite this, the exclusive association of semi-clean crop stores with cereals, and their overall dominance within the archaeobotanical assemblage from this part of the settlement, points to a link between cereals and institutional contexts of storage.
Regional farming systems in Late Bronze Age western Anatolia
Crop choice
While the small size of the archaeobotanical assemblage from Çine-Tepecik means that the presence/absence of individual crops must be treated with caution, several notable patterns emerge when it is compared with those from other Late Bronze Age sites in western Anatolia. The comparable abundance of barley and free-threshing wheat at Çine-Tepecik is primarily due to a single rich sample that contained 370 grains of free-threshing wheat (sample 7, see Table S1). The much greater ubiquity of barley reflects its more consistent presence within the overall assemblage. This is consistent with the dominance of barley within cereal assemblages at both Kaymakçı (Shin et al. Reference Shin, Marston, Luke, Roosevelt and Riehl2021) and Troy (Riehl Reference Riehl1999), although free-threshing wheat was also recovered in significant quantities from Kaymakçı. Broomcorn millet was also recovered from Troy (Riehl Reference Riehl1999: 46) and Perge (Kroll Reference Kroll, Martini and Eschbach2017). The pulse assemblage from Çine-Tepecik diverges from Kaymakçı, Troy and Perge, where bitter vetch was recovered in greater quantities than lentil. Numerous finds of chickpea are also known from Kaymakçı and Troy but very few were found at Çine-Tepecik and they are absent from Perge. The absence of olive at Çine-Tepecik is comparable with Kaymakçı but contrasts with Troy and Perge. Elsewhere in western Anatolia, remains of barley, free-threshing wheat, glume wheats, lentil and bitter vetch were recovered from Late Bronze Age Beycesultan (Helbaek Reference Helbaek1961). This variability attests to the absence of a singular farming tradition across western Anatolia, aligning with historical and archaeological evidence for distinct local identities across the region (Mac Sweeney Reference Mac Sweeney2010).
Despite differences in the relative abundance of taxa, the spectrum of crops at Çine-Tepecik does correspond with evidence from Kaymakçı reflecting a hybrid suite of farming practices that combines elements from central Anatolia and the Aegean (Marston et al. Reference Marston, Çakırlar, Luke, Kováčik, Slim, Shin and Roosevelt2021; Shin et al. Reference Shin, Marston, Luke, Roosevelt and Riehl2021). As at Çine-Tepecik and Kaymakçı, free-threshing wheat was recovered in significant quantities at Kuşaklı (Pasternak Reference Pasternak1998), Kaman-Kalehöyük (Fairbairn & Omura Reference Fairbairn and Omura2005) and Oymaağaç Höyük (Czichon et al. Reference Czichon2016) in central Anatolia. Riehl and Nesbitt (Reference Riehl, Nesbitt, Fischer, Genz, Jean and Köroğlu2003) suggest that the use of free-threshing wheats in central Anatolia distinguishes crop spectra in this region from those in the Aegean, where glume wheats were more important. More recent finds of free-threshing wheat from Midea (Margaritis et al. Reference Margaritis, Demakopoulou, Schallin, Touchais, Laffineur and Rougemont2014), Ayios Vassileios (Karathanou Reference Karathanou2019) and Ourania (Sarpaki Reference Sarpaki and Kopaka2009) in the southern Aegean and large deposits of glume wheats from Hattusha (Diffey et al. Reference Diffey, Neef, Seeher and Bogaard2020) and Kuşaklı (Pasternak Reference Pasternak1998) in central Anatolia suggest that this distinction may be less divisive than previously thought. Clearer regional differences are visible in the ubiquity of olive in the Aegean and its absence from central Anatolia, where winter frost hinders its cultivation, as well as in the more limited presence of millet in central Anatolia than the Aegean in the Late Bronze Age. As noted by Shin and colleagues (Reference Shin, Marston, Luke, Roosevelt and Riehl2021), olive grows wild in the environs of Kaymakçı and Çine-Tepecik today, suggesting that its absence from Late Bronze Age assemblages at the sites reflects a regional practice that links communities of inland western Anatolia to the traditions of central Anatolia. In contrast, the presence of millet at Çine-Tepecik, Troy and Perge provides a link with the Late Bronze Age Aegean. Again, this is consistent with evidence from historical and archaeological records, with Hittite texts attesting to both Hittite and Mycenaean political influence in western Anatolia (Bryce Reference Bryce2005: 193) and locally produced artefacts combining traditions from both neighbouring regions (Günel Reference Günel, Weeden and Ullman2017; Roosevelt & Luke Reference Roosevelt and Luke2017).
Farming and the political economy
Archaeobotanical remains from refuse deposits at Çine-Tepecik attest to a broad range of crops that may have been grown at the site. The cultivation of diverse suites of cereals and pulses was common practice for recent pre-mechanised farmers in the Mediterranean engaged in domestic production (Halstead Reference Halstead2014: 283) and characterises archaeobotanical assemblages from domestic contexts at Late Bronze Age Troy (Riehl Reference Riehl1999: 33–36) and Beycesultan (Helbaek Reference Helbaek1961). The refuse deposits from Çine-Tepecik may therefore represent household waste and the by-products of crops processed within the context of domestic production and/or consumption. In contrast, residues of barley and free-threshing wheat stores associated with central storage contexts suggests that institutional involvement with the staple economy may have focused on cereals.
A similar contrast in crop species between domestic and institutional contexts is apparent in both central Anatolia and the southern Aegean. Cereals dominate samples taken from large stores of taxed grain in the Hittite capital of Hattusha and the provincial capital of Kuşaklı (Pasternak Reference Pasternak1998; Diffey et al. Reference Diffey, Neef, Seeher and Bogaard2020). At the smaller settlement of Kaman-Kalehöyük, large storage pits were found to contain staining in the shape of charred wheat grains, contrasting with the diverse range of crops recovered from refuse deposits (Fairbairn & Omura Reference Fairbairn and Omura2005). In the southern Aegean, Linear B texts reveal a palatial focus on a narrow range of cereals—wheat and barley—(Halstead Reference Halstead1995), while domestic and refuse contexts from Tiryns (Kroll Reference Kroll1982), Tsoungiza (Allen & Forste Reference Allen, Forste, Wright and Dabney2020), Mycenae (Hillman Reference Hillman, Hillman, French and Sherratt2011) and Midea (Margaritis et al. Reference Margaritis, Demakopoulou, Schallin, Touchais, Laffineur and Rougemont2014) contained a diversity of cereals and pulses.
These contrasts plausibly reflect the different aims of arable farming within domestic and institutional contexts. Recent farmers in the Mediterranean producing for domestic consumption cultivated a wide range of crops to spread the risk of failure across species with differing ecological requirements and the labour requirements of harvesting across the season (Halstead Reference Halstead2014: 283–84). In contrast, the difficulty of reaping scrambling pulses on a large scale meant that farmers aiming at overproduction relied on a narrow range of cereals that were easier to harvest and transport. This facilitated the use of ‘extensive’ farming systems in which draught animals enabled cultivation on scales sufficient to produce significant arable surplus (Halstead Reference Halstead2014: 36, 104–5). Such systems would be consistent with the large scales of storage within institutional contexts in both the southern Aegean (Christakis Reference Christakis2008: 120–21) and central Anatolia (Pasternak Reference Pasternak1998; Diffey et al. Reference Diffey, Neef, Seeher and Bogaard2020), reflecting top-down concerns with the mass production and mobilisation of farming products.
While more evidence is needed, our proposed link between cereals and institutional storage at Çine-Tepecik therefore suggests that the production and mobilisation of arable surplus may have formed a major part of the regional political economy. Elsewhere in western Anatolia, large storage pithoi were also found within dedicated magazines in the citadel of Troy, the proposed capital of the kingdom of Wilusha (Jablonka Reference Jablonka, McMahon and Steadman2011), similarly indicating the centralisation of farming products within institutional contexts (Thumm-Doğrayan et al. Reference Thumm-Doğrayan, Pavúk, Pieniążek, Garcia, Orgeolet, Pomadère and Zurbach2019). In contrast, storage in the inner citadel of Kaymakçı, thought to have been the capital of the Seha River Land (Roosevelt & Luke Reference Roosevelt and Luke2017), was dominated by semi-subterranean circular features associated with routine residential activities (Roosevelt et al. Reference Roosevelt2018). This points to limited top-down integration of agricultural production within the political economy, although further excavations may reveal institutional contexts of storage. As with farming strategies themselves, therefore, the political economy of farming also varied across Late Bronze Age western Anatolia, hinting at diverse forms of political organisation across the region. Once more, the archaeobotanical evidence aligns with historical records.
The spread of millet in Anatolia and Europe
The timing and direction of the spread of broomcorn millet following its domestication in northern China has been a major focus of recent archaeobotanical research. The grains from Çine-Tepecik contribute to a growing number of finds from prehistoric Anatolia. Despite its potential role as a conduit between Asia and Europe, however, the distribution of millet across the region has received little attention. Here, we synthesise reports of millet from Bronze and Iron Age Anatolia and assess their implications for its spread. The locations of the sites discussed are shown in Figure 7.
By radiocarbon dating early finds of millet across Europe, Filipović and colleagues (Reference Filipović2020) found that cultivation began on the continent as early as the sixteenth century BC. The earliest finds are from modern-day Ukraine, consistent with the spread of millet into Europe through central Asia (Miller et al. Reference Miller, Spengler and Frachetti2016; Martin et al. Reference Martin2021), but Filipović and colleagues also highlight a possible route into the Aegean from Anatolia. Large deposits of millet grain have been recovered from Late Bronze Age contexts at sites in the northern Aegean (Valamoti Reference Valamoti2016). While finds have also been reported from Neolithic and Early Bronze Age contexts, significant quantities of grain have been recovered from only one site and these have not been directly dated. Earlier finds may therefore represent later intrusions. The earliest directly dated grains from the northern Aegean belong to the first half of the fifteenth century BC (Valamoti Reference Valamoti2023: 54). Finds from the southern Aegean are more limited and are largely restricted to Late Bronze Age contexts (Kroll Reference Kroll1982; Livarda & Kotzamani Reference Livarda and Kotzamani2013).
The only directly dated millet grains from Anatolia are from the east, with grains from Sos Höyük, Erzurum, dated to 1270–1040 cal BC (Longford et al. Reference Longford, Drinnan, Sagona, Fairbairn, O'Connor and Marwick2009; Martin et al. Reference Martin2021). Elsewhere in eastern Anatolia, millet was recovered from Middle Bronze Age (c. 2000–1600 BC) contexts at Ziyaret Tepe in Diyarbakır (Rosenzweig Reference Rosenzweig2014: 160, tab. 5). Four grains were also recovered from Late Bronze Age levels from this site. On the eastern central plateau, six grains of foxtail millet (Setaria italica (L.) P. Beauvois) are reported from Late Bronze Age and Early Iron Age contexts at Kuşaklı, Sivas (Pasternak Reference Pasternak1998). These finds point to the expansion of millet into eastern Anatolia from north-east Mesopotamia/Iran and/or the Caucasus, where grains have been directly dated to the sixteenth century BC (Martin et al. Reference Martin2021).
In central Anatolia, broomcorn millet was recovered in large quantities from Middle Bronze Age Kültepe and as sporadic single grains from Late Bronze Age Kaman-Kalehöyük (Fairbairn pers. comm.). Further north, a small number of grains identified as belonging to the grass subfamily Panicoideae (which contains numerous species including broomcorn millet) have been recovered from contexts dating to the mid-thirteenth to the early twelfth centuries BC at Oymaağaç Höyük (C. Rössner pers. comm.). Grains of broomcorn millet were also found in significant quantities in contexts dating to the twelfth century BC at Kınık Höyük, southern Cappadocia (Castellano et al. Reference Castellano, Campana, Crabtree, Gürel, Kuzucuoğlu, Matessi, d'Alfonso, Marchetti, Campeggi, Cavaliere, D'Orazio, Giacosa and Mariana2023) and in smaller quantities at Kilise Tepe, Mersin (Bending & Colledge Reference Bending, Colledge, Postgate and Thomas2007: 588, tab. 34, 593). Nine grains of foxtail millet are reported from Early Iron Age (c. twelfth century–950 BC) Gordion, Ankara, in addition to 161 grains from Late Phrygian (540–330 BC) levels (Miller Reference Miller2010: 57, tab. 5.13). In western Anatolia, in addition to Çine-Tepecik, grains of broomcorn millet have been recovered from Troy, Çanakkale, from an occupation phase dating to the eighteenth to fourteenth centuries BC (Riehl Reference Riehl1999: 46), alongside two grains from Late Bronze Age Perge, Antalya (Kroll Reference Kroll, Martini and Eschbach2017).
Recent redating projects have revealed numerous instances where directly dated millet grains belong to significantly later periods than the archaeological contexts in which they were found (Filipović et al. Reference Filipović2020; Martin et al. Reference Martin2021). This highlights the tendency of millet to intrude into earlier contexts and, therefore, the limitations in interpreting the temporal distribution of finds that have not been directly dated. Despite this, the finds of millet from Anatolia offer some interesting possibilities. It is likely that the crop first entered the region from the east, with the direct dating of grains from neighbouring regions broadly consistent with the Bronze Age contexts of grains from eastern Anatolia. Broadly contemporary and later finds from central Anatolia suggest that the crop spread west and could have entered the Aegean from western Anatolia. In the absence of direct dating, the lack of Iron Age occupation at Çine-Tepecik provides relatively strong evidence for the presence of millet in western Anatolia during the Late Bronze Age, aligning the site with directly dated finds from the northern Aegean. Current evidence suggests that, in this scenario, millet would have spread from Anatolia to Greece only after it had entered Europe from central Asia (as the Ukrainian finds pre-date grains from the Aegean). Alternatively, however, it is notable that the earliest contexts containing millet across west-central and western Anatolia come from Troy on the western coast. The broad contemporaneity of these contexts with those elsewhere in the Aegean could point to the eastward spread of millet into western Anatolia, potentially as part of an influx of Aegean imports during the Late Bronze Age (cf. Pieniążek et al. Reference Pieniążek, Pavúk, Kozal, Nessel, Neumann and Bartelheim2018). Both more finds and the direct dating of millet grains from Anatolia are needed to clarify this picture further.
Conclusion
Archaeobotanical remains from Çine-Tepecik have provided insights into the nature and political economy of arable farming within Late Bronze Age western Anatolia. Grains of millet provide strong evidence for the presence of this crop in the Late Bronze Age which, with further finds and analysis, may shed light on the timing and direction of the spread of millet between Anatolia and the Aegean. The range of crops at Çine-Tepecik contributes to a variable picture of crop choice across western Anatolia, but, while based on a small dataset, the discovery also supports the suggestion that farming practices within the region constituted a hybrid between those of central Anatolia and the Aegean. Compositional analysis of archaeobotanical remains suggests that domestic consumption utilised a range of cereal and pulse crops but that institutional involvement in agriculture may have focused on cereals. This resembles the elite agro-economies of Late Bronze Age central Anatolia and the southern Aegean and suggests that arable farming may also have played a key role in the political economy of Çine-Tepecik. Variability in the political economies of farming across western Anatolia aligns with textual and archaeological evidence suggesting that Arzawa constituted a loose alliance of autonomous kingdoms with distinct regional identities.
