Ojakly: A Late Bronze Age mobile pastoralist site in the Murghab Region,Turkmenistan

Abstract

Excavations at Ojakly (site 1744) in the Murghab alluvial fan in Turkmenistan mark the first systematic collection of archaeological materials related to Bronze Age mobile pastoralists in the region, and the earliest evidence to date of their occupation patterns, subsistence practices, and ceramic production activities. Because the appearance of mobile pastoral groups in the Murghab during the Late Bronze Age (ca. 1950–1500 b.c.) is traditionally associated with significant changes in regional sociopolitical structures, these data are important for establishing local strategies of and the relationship between sedentary agricultural and mobile pastoral populations. Here, we present ceramic, faunal, archaeobotanical, and lithic data that force us to reconsider the traditional sedentary-mobile dichotomy. Specifically, we find that while the subsistence economies are distinct at urban and non-urban sites, the ceramic production and trade interactions are significantly intertwined and more complex than previously acknowledged for this time period. Additionally, the presence of a ceramic kiln at Ojakly (Turkmen for “place with kiln”) containing unfired ceramics of a type typically associated with sedentary farmers in the Bronze Age Murghab suggests the transfer of technical knowledge between groups who nevertheless maintained distinct material cultural identities. Ojakly provides important new data about coexisting economies in the Late Bronze Age Murghab that can productively unsettle traditional notions of dominance, control, and polarization in sedentary-mobile interactions.     

Patterns of pastoralism in later Bronze Age Kazakhstan: new evidence from faunal and lipid residue analyses

Current research themes relating to prehistoric Central Asian pastoralism are discussed, and the Neolithic to Bronze archaeological sequence in Kazakhstan is briefly outlined. The results of new faunal analyses of six later Bronze Age sites in Central and Northern Kazakhstan are presented. These studies are based upon the analysis of 63,529 bone fragments, of which 27,023 were identifiable to species and element. These assemblages are compared with 16 other sites in Central and Northern Kazakhstan, and the Trans-Ural region. The herd structures at the final Bronze Age site of Kent are discussed in detail. Analyses of absorbed lipid residues from four sites are also presented. In total, 140 pottery sherds were analysed, of which 73 provided sufficient residues for stable isotope ratio determinations. It is concluded that species proportions are highly variable regionally. Cattle are most prevalent in the forest steppe zone, whilst caprines become more common in semi-arid steppe regions. Proportions of horse are particularly variable, even within environmentally similar areas. Lipid residue results indicate the high prevalence of ruminant dairy products in pottery vessels, whilst faunal data from Kent suggests that cattle husbandry might have been particularly focussed on milk, in comparison with sheep and goats. The significance of horses within prehistoric pastoralism is discussed.     

Stable isotope dietary analysis of prehistoric populations from the Minusinsk Basin,Southern Siberia,Russia: a new chronological framework for the introduction of millet to the eastern Eurasian steppe

We report the results of stable carbon and nitrogen isotope analysis of 354 human and faunal samples from five archaeological cultures of the Minusinsk Basin, Southern Siberia – Afanasyevo, Okunevo, Andronovo, Karasuk and Tagar (ca. 2700–1 BC) – a key location in Eurasia due to its position on a northern corridor linking China and central Eurasia. The results indicate that the diet of Eneolithic to Middle Bronze Age (Afanasyevo to Andronovo) populations was primarily C₃-based, with C₄ plants only becoming an important component of the diet in the Late Bronze Age Karasuk and Early Iron Age Tagar cultures. Freshwater fish seems to have been an important constituent of the diets in all groups. The findings constitute the earliest concrete evidence for the substantial use of millet in the eastern Eurasian steppe. We propose that it was probably introduced from Northwestern China during the Karasuk culture at the start of the Late Bronze Age, ca. 1500 BC. We conclude with a discussion of the implications for the nature of pastoralist economies on the steppes.     

Painted plaster from Bronze Age Thebes, Boeotia (Greece): a technological study

From the rather difficult excavations that have taken place in Thebes since the beginning of the last century, many fragmentary but often well-preserved paintings on plaster have been unearthed. These belong to several contexts and periods: House of Kadmos (Late Helladic IIIA), Treasury Room (Late Helladic IIIB1) and Oikopedon Spourli (Late Helladic III). Their iconography, style and technology fit well with other paintings from the Late Bronze Age sites found in the vicinity of Thebes (e.g. Gla and Orchomenos). This paper presents a technological study of the Bronze Age painted plaster from Thebes, Greece. The paintings were investigated by means of X-ray diffraction; stereo, reflected light and scanning electron microscopy; some by laser-induced breakdown spectrometry and by micro-Raman spectroscopy, in order to identify the pigments and the composition of the plaster layers, and to determine the painting technique(s) that the artisans may have employed. The plaster layer onto which the paint layer was applied was often the only layer and consisted mainly of calcite, while a clay plaster formed the backing between the lime plaster coat and the actual wall surface. The pigments identified were: yellow ochre, haematite (red), cuprorivaite (Egyptian blue), indigo and possibly riebeckite for blue, charcoal (black), calcite (white), and a combination of black and red for purple. A detailed macroscopic study of the painted surface revealed several features, which indicated that the technique of al fresco painting was employed extensively, a technique already in use since the start of the Late Minoan I phase on Crete. A generally lower level of quality in the appearance of the later paintings (Treasury Room and Oikopedon Spourli) was also noted, but this was not reflected in the materials used or in their overall manipulation.     

Characterization and textural analysis of Middle Bronze Age Transdanubian inlaid wares of the Encrusted Pottery Culture,Hungary: a preliminary study

Inlaid ceramics belonging to the Encrusted Pottery Culture and dated to the Middle Bronze Age (2000–1500 BC) are highly distinctive vessels with complex decorative motifs found in large numbers in the Transdanubia region of Hungary. Despite this considerable corpus of material there has been little systematic investigation of the composition of the inlays. Micro-analysis of Transdanubian inlaid wares by X-ray diffraction (XRD), micro-Fourier transform infrared microscopy (FT-IR), and scanning electron microscopy (SEM) provides new compositional, structural and textural information on the inlays. In contrast to common statements in the literature regarding the materials used to make inlays, these new data show that the majority of inlays are composed of hydroxyapatite (bone) that was previously ashed, although some of the inlays are composed of calcium carbonate. Additional compositional and textural variation in the bone inlays suggests that bone material from different skeletal elements and/or of different age may have been used, and that contrasting recipes for inlay preparation were employed during fabrication. These results suggest that the production of inlaid vessels of the Encrusted Pottery Culture was more complex than has hitherto been thought.     

Provenance study of early and middle bronze age pottery from Kaman-Kalehöyük,Turkey, by heavy mineral analysis and geochemical analysis of individual hornblende grains

The provenance of Early Bronze Age and early Middle Bronze Age pottery produced between 2100 and 1970 B.C. and excavated from Kaman-Kalehöyük, Turkey was studied using mineralogical methods, including heavy mineral analysis and geochemical study of individual hornblende grains. The relative abundances of heavy minerals in the fabrics of 20 Early Bronze Age (EBA) and early Middle Bronze Age (MBA) pottery sherds, together with 27 local sediments collected within a radius of 25 km of the site were studied. The heavy mineral distributions in the Kaman region were statistically analyzed for consistencies in their occurrence. Amphibole was found to be the most abundant heavy mineral in most of the analyzed samples, followed by titanite and epidote. The amounts of other minerals such as garnet, clinopyroxene, and zircon are subordinate. Different proportions of heavy minerals in the fabrics allow categorization of the EBA and early MBA potteries into 5 groups. Comparative study of heavy mineral assemblages of local sediments and pottery suggests that half of the EBA and most of the MBA potteries were produced from sediment near the excavation site, whereas the other half of the EBA potteries were produced from sediment occurring at 25 km east or more east of the site. The geochemistry of individual amphibole grains was studied by electron-microprobe analysis. Most of the studied amphibole grains are calcic and aluminous, corresponding to hornblende. They can be further characterized into four types based on their chemical composition. The combination of heavy mineral identity and hornblende geochemistry provides diagnostic evidence for the origins of Kaman-Kalehöyük pottery. These and analogous heavy mineral techniques are effective archaeometric tools for determining pottery provenance.     

Exchange patterns,boundary formation,and sociopolitical change in Late Bronze Age Southern Caucasia: preliminary results from a pottery provenance study in northwestern Armenia

In the South Caucasus—roughly the territory of today's Armenia, Georgia, and Azerbaijan—the transition from the Middle Bronze Age (MBA) to the Late Bronze Age (LBA) is equated with fundamental shifts in settlement patterns, subsistence economy, and political strategies. During the mid-2nd millennium BC, nomadic pastoral societies that had dominated the region began to settle down and construct stone fortresses along the foothills of the Lesser Caucasus; these fortifications largely replaced the expansive and often opulently adorned kurgan burials as the most prominent expression of political dominance on the landscape. After a decade of intensive archaeological study at various fortifications, very little remains known about the political and economic relationships among fortresses on a regional scale that might improve our understanding of the roots of these sociopolitical transformations. In this paper, we highlight the results of a recent neutron activation analysis (NAA) of ceramics from elite and non-elite contexts at a selection of LBA fortresses on the Tsaghkahovit Plain in northwestern Armenia, and offer some preliminary interpretations about political and economic organization and boundary formation. Most strikingly, the NAA data suggest that the fortresses on the Tsaghkahovit Plain appear to have isolated themselves economically from surrounding valleys, perhaps in an attempt to forge boundaries and legitimating ideologies attendant to new political formations that were quite distinct from their nomadic predecessors in the MBA.     

XRF analysis of glass beads from the Mycenaean palace of Nestor at Pylos,Peloponnesus, Greece: new insight into the LBA glass trade

In recent years there has been a growing interest in Mycenaean glass among archaeologists and scientists. Scholars have traditionally thought that all Mycenaean glass was imported either in finished form or as ingots and simply shaped or worked at the Mycenaean sites. Chemical studies of other Mycenaean glass (50 and 43) support the hypothesis that glass was imported into Mycenaean Greece, but there is also indication for glass production in mainland Greece at the palace of Thebes (Nikita and Henderson, 2006). There is no evidence for glass making or working at the Palace of Pylos, yet there is an abundance of glass beads there. The aim of this paper is to identify the technology and source for the glass of these beads and thus to ascertain how Pylos was connected to the broader Mycenaean and Mediterranean economies. The composition of the glasses was determined by means of portable XRF analysis and compared to that of other Late Bronze Age glasses from Egypt, Mesopotamia and mainland Greece. Four blue beads coloured with cobalt and one blue bead coloured with copper have Ti and Zr compositions consistent with an Egyptian origin of manufacture while five other beads show Ti and Zr concentrations consistent with a Mesopotamian origin (Shortland et al., 2007). Based on the dearth of Egyptian and Mesopotamian imports in Pylos, the presented data support the hypothesis that Pylos was receiving via internal Greek trade routes foreign-produced glass, which may have been worked abroad or in Greece.     

Bronze Age landscape dynamics: spatially detailed pollen analysis from a ceremonial complex

The late Neolithic and early Bronze Age are periods marked by the construction of conspicuous concentrations of ‘ritual’ complexes, used for funerary rituals, seasonal gatherings and communal activities. Understanding the environmental context of monuments may provide detailed insights into relationships between the physical environment and the activities undertaken at individual monuments. Raised burial mounds (barrows) are generally assumed to have been constructed in open landscapes (the so-called ‘landscape openness’ hypothesis) thus rendering them highly visible in the surrounding landscape. This paper seeks to test to what extent vegetation (and in particular openness) around a dense concentration of barrows was actively managed, using three pollen sequences in close spatial juxtaposition to the archaeology. The local vegetation histories, supported by radiocarbon dating, demonstrate spatial differences in vegetation pattern both during the time of monument construction and use (c. 2000–1500 cal BC) and during subsequent periods. They do not support the ‘landscape openness’ hypothesis. This suggests that there is no single ‘blueprint’ for vegetation structure on and around these types of monument complexes. There is no evidence for major restructuring of the landscape during the early Bronze Age. The data describe a major transformation of the vegetation around 1500 cal BC (the Middle Bronze Age) in an area not known for archaeology of this date. This serves to emphasize the role of palaeoecology in augmenting the archaeological record of landscape re-organisation and transformation in prehistory.     

Defining the Early Bronze Age landscape: a remote sensing‐based analysis of Hafit tomb distribution in Wadi Andam,Sultanate of Oman

High‐resolution, freely available Google Earth software was successfully utilised in a remote‐sensing survey to locate and map thousands of Hafit tombs in a study area centring on Wadi Andam in the Sultanate of Oman. This dataset was refined for reliability with ground‐based fieldwork, and was analysed in the landscape using GIS software. The tombs are not randomly distributed across the study area; rather, the hydrology of the area appears to have been a dominant determining factor in the location of the graves. The structures were constructed in elevated, highly visible locations, possibly in an attempt to mark ownership of the landscape. The distribution of Hafit tombs is likely to provide some insight into the utilisation of the landscape in this period, with the evidence from Wadi Andam tentatively suggesting the presence of a nomadic pastoralist population. The development of this rapid, accurate and cost‐effective methodology has the potential to greatly facilitate the survey and analysis of Hafit tombs across the Oman peninsula.     

Strontium isotope analysis and human mobility during the Neolithic and Copper Age: a case study from the Great Hungarian Plain

From the Late Neolithic to the Early Copper Age on the Great Hungarian Plain (4500 BC, calibrated) a transformation in many aspects of life has been inferred from the archaeological record. This transition is characterized by changes in settlements, subsistence, cultural assemblages, mortuary customs, and trade networks. Some researchers suggest that changes in material culture, particularly the replacement of long-occupied tells with smaller, more dispersed hamlets, indicates a shift from sedentary farming villages to a more mobile, agropastoral society that emphasized animal husbandry and perhaps secondary products of domestication. In a previous study (Giblin, 2009), preliminary radiogenic strontium (⁸⁷Sr/⁸⁶Sr) isotope data from human dental enamel showed that Copper Age individuals expressed more variable isotope values than their Neolithic predecessors. These data provided support for the idea that Copper Age inhabitants of the Plain were acquiring resources from a greater geographic area, findings that seemed consistent with a more mobile lifestyle. In this article a larger sample from human and animal skeletal material is used to re-evaluate earlier work and shed new light on the transition from the Neolithic to the Copper Age in eastern Hungary. The expanded sample of strontium isotopes from human dental enamel shows that ⁸⁷Sr/⁸⁶Sr values are more variable during the Copper Age, but the change is more pronounced in the Middle Copper Age than in the Early Copper Age. These results, along with recently published complementary research, indicate that the transition from the Late Neolithic tell cultures of the Plain to the more dispersed Copper Age hamlets was more gradual than previously thought, and that the emergence of an agropastoral economy does not explain changes in settlement and material culture.     

Insights from a tribological analysis of the tribulum

Since the 1980s, “strange” microwear traces were found to occur on flint blades from sites in the Near East from the late Neolithic and occurring in great abundance by the Early Bronze Age. Although these were considered by archaeologists to be sickles because they had visible gloss on their edges, their use-traces could not be reproduced in harvesting experiments carried out in the field. Subsequently, several lines of evidence were used to study the blades, including not only direct observation of microscopic wear traces, but also Near Eastern cuneiform texts from the third and second millennium BC describing agricultural instruments and analogy with ethnographic and experimental reference material. We found that these tools and their traces best matched traces on flint used to arm the underside of a tribulum (threshing sledge) for threshing grain and cutting straw. We built a replica of the tribulum described in cuneiform texts from the Bronze Age, using copies of the Bronze Age blades, and used this instrument in experiments.     

New light on old pumice: the origins of Mediterranean volcanic material from ancient Egypt

This paper presents and discusses the Neutron Activation Analysis (NAA) results newly obtained from pumice pieces found decades ago at the Egyptian sites of Maiyana, Sedment, Kahun, and Amarna – now in the collections of the Ashmolean Museum, Oxford, and the Petrie Museum of Egyptian Archaeology, London – which could be successfully related to several volcanic eruptions in the Mediterranean. The work contributes to the constant accumulation of knowledge concerning the first appearance of pumice from the so-called Minoan eruption of the Santorini volcano. In addition, it unexpectedly sheds more light on the long-distance trade of Mediterranean volcanic material in the Bronze Age world by disclosing another connection between Lipari and the Eastern Mediterranean.     

The development of animal husbandry from the Late Iron Age to the end of the Roman period: a case study from South-East Britain

In this paper zooarchaeological evidence from Iron Age and Roman sites in South-East Britain is presented and the results are applied to the continuing debate over culture contact and change following the Roman invasion. Evidence from Heybridge in Essex indicates that there were two stages of livestock development. These may reflect the import of new breeding stock into Britain. Differences between the rate of livestock development at this rural site and the nearby urban centre of Colchester indicate differing mechanisms of animal supply between the two sites. The appearance of very large cattle in Late Roman contexts at Boreham in Essex suggests that improvement of animals continued throughout the Roman occupation and was not merely an initial response to new economic and administrative demands. The biometrical evidence from these three sites is compared with evidence from elsewhere in Europe and the development of livestock during the Roman Period is shown to be complex and varied. The impetus and ideology behind the changes in animal husbandry following the Roman invasion in Britain are explored.     

Residential mobility and social identity in the periphery: strontium isotope analysis of archaeological tooth enamel from southeastern Arabia

Strontium isotope analysis represents an effective means of assessing mobility and reconstructing geographic residence patterns in archaeological populations. This biogeochemical technique was utilized to test the hypothesis that burgeoning interregional exchange networks and the occurrence of exotic grave goods in local tombs would correspond with a highly mobile population and a considerable immigrant presence during the Umm an-Nar (2700–2000 BC) period in the UAE. This region has been considered peripheral relative to larger civilizations in Mesopotamia and the Indus Valley, but played an important role as a major supplier of copper for the Persian Gulf. Individuals (n = 100) from six monumental Umm an-Nar tombs (Mowaihat; Tell Abraq; Umm an-Nar Island I, II, V; Unar 1) were selected to evaluate the geographic origins of tomb members. Mean ⁸⁷Sr/⁸⁶Sr ratios from local individuals interred at Mowaihat (0.708863 ± 0.000014; 1σ, n = 12), Tell Abraq (0.708873 ± 0.000020; 1σ, n = 27), Umm an-Nar Island (0.708902 ± 0.000079; 1σ, n = 33), and Unar 1 (0.708805 ± 0.000065; 1σ, n = 25) all display little isotopic variability, indicative of a population that was not highly mobile. However, coupled with archaeological evidence, three immigrants from Tell Abraq (n = 2) and Mowaihat (n = 1) identified by deviant strontium values suggest that this region was actively engaged in interregional interaction. Despite claims that these tombs acted as visible markers of territoriality legitimized by local ancestors buried within them, the presence of non-locals suggests that as commerce became increasingly important, definitions of kinship and social identity may have become more flexible to better meet the needs of the local community and those with whom they interacted.     

Middle Bronze Age metallurgy in the Levant: evidence from the weapons of Byblos

This paper constitutes a synthesis of a technological investigation on copper base alloy weapons from Byblos. Most of the weapons are typical of the Middle Bronze Age in the Levant. Methods such as metallographic examination and chemical analyses by EDS were used to identify the different stages of the chaîne opératoire used in the making of these weapons. The results reveal precise information regarding the production of several types of weapons such as the type and performance of the moulds used for casting and the deformation process. Furthermore, these results highlight the contribution of economic and cultural factors in the choice of components in a copper base alloy recipe. Finally, the use of silver–copper brazes for joining copper base alloy objects is recorded for the first time for the period and region concerned.     

Ancient DNA analysis of desiccated wheat grains excavated from a Bronze Age cemetery in Xinjiang

Wheat has been one of the most important crop in Eurasia since the Neolithic period. Understanding the spread of wheat cultivation is crucial to understanding the spread of agriculture as a whole and the interactions between prehistoric populations across the Eurasian continent. However, the routes by which wheat cultivation spread eastwards have been poorly understood to date, due to the scarcity of plant remains recovered from archaeological sites. Desiccated wheat grains excavated from the Xiaohe cemetery in Xinjiang, and dated to the early Bronze Age, show excellent DNA preservation. Here we present an ancient DNA (aDNA) analysis of wheat (Triticum sp.) grains excavated from Xiaohe and provide the first definitive evidence for bread wheat in China during the Bronze Age. The nuclear ribosomal DNA internal transcribed spacer regions (ITS1 and ITS2) and the intergenic spacer region (IGS) were amplified. The IGS region within the D genome of wheat has a 71 bp insertion that is absent from corresponding regions in the A and B genomes. The results showed that the Xiaohe wheat showed most sequence similarity to hexaploid bread wheat (Triticum aestivum), including the characteristic insertion into the D genome. The presence of bread wheat at the Xiaohe cemetery is discussed in relation to it having spread into Xinjiang by the Bronze Age, providing new insight into the origins of bread wheat in East Asia.     

An archaeological signature of multi-level social systems: The case of the Irish Bronze Age

Recent research suggests that contemporary human social groups are structured according to principles of fission and fusion that are also observed in some of our primate relatives, raising the possibility that such social systems have been a feature of hominin society throughout prehistory. The current paper examines the possibility of identifying archaeological signatures of multi-level social structures through the examination of site size distributions. Data on the sizes of Irish Bronze Age stone circles and predictions for the size of aggregations they could accommodate are compared with simulations parameterized using data on modern human groups. The results suggest that the presence of hierarchically inclusive, multi-level social structures provides a better explanation for the data than more traditional archaeological accounts based on the rank-size rule and related inferences concerning the emergence of political elites.
