The use of SEM-EDS,PIXE and EDXRF for obsidian provenance studies in the Near East: a case study from Neolithic Çatalhöyük (central Anatolia)

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies.     

SOURCING OBSIDIAN FROM NEOLITHIC ÇATALHÖYÜK (TURKEY) USING ENERGY DISPERSIVE X‐RAY FLUORESCENCE*

This paper details the chemical sourcing of 42 obsidian artefacts from a single Neolithic structure at Çatalhöyük (central Anatolia), using Energy Dispersive X‐Ray Fluorescence (EDXRF). The chemical signatures of the samples match those of two geological sources in southern Cappadocia: East Göllü Da? and Nenezi Da?. The data provide a counterpoint for previous analyses at the site, and suggest possible intra‐community distinctions with regard to shifts in raw material procurement and technical change.     

Networks and Neolithisation: sourcing obsidian from Körtik Tepe (SE Anatolia)

This paper details the use of obsidian sourcing to reconstruct networks of interaction (or ‘communities of practice’) amongst populations of south-eastern Anatolia and the Near East in the context of ‘Neolithisation’ during the late 11th–early 10th millennia BC. EDXRF was used to elementally characterise 120 artefacts of Epi-Palaeolithic – Pre-Pottery Neolithic A date from Körtik Tepe in south-eastern Anatolia. Four eastern Anatolian sources are represented, mainly Bingöl A/B and Nemrut Da?, plus the first evidence for the use of Mu? obsidian. When the source data is integrated with the artefacts' techno-typological attributes it is possible to locate the assemblage within an Upper Tigris tradition (with some interesting local differences), which stands in stark contrast to contemporary practices in northern Mesopotamia and the Levant. These local and regional distinctions support recent views of the Neolithic being much more heterogeneous, with a ‘mosaic’ of community-specific/local traditions of subsistence practices, raw material choices and lithic technologies during the Younger Dryas–Early Holocene.     

Non-destructive PXRF analysis of museum-curated obsidian from the Near East

Non-destructive pXRF has the potential to expand sample populations of archaeological provenancing studies by facilitating access to museum collections of artefacts. In this study, we use museum-curated obsidian for the sites of Tell Brak, Mersin-Yümüktepe and Tell Arpachiyah and geological obsidian samples from central Turkey to demonstrate that non-destructive pXRF is comparable to other techniques in differentiating between Near Eastern obsidian sources. Secondly, we use multivariate analysis to evaluate whether non-destructive pXRF is sufficiently accurate and precise to enable comparison with legacy datasets from previous analysis using PIXE and ICP-MS. Multivariate analyses show that instrumental offsets between the results from pXRF and other analytic techniques are less than source-to-source variation typical for most Anatolian obsidian outcrops and pXRF-identified geochemical groups are directly comparable to legacy datasets. Non-destructive pXRF analysis indicates that during the Chalcolithic, East Göllü da? and Nenezi da? continued to be the major sources of obsidian to communities in central Anatolia and the Bingöl range and mountains surrounding Lake Van supplied sites east of the Levant. Variations in the analysed assemblages suggest a number of obsidian exchange networks existed during this period.     

Remodeled human skulls in Köşk Höyük (Neolithic age,Anatolia): a new appraisal in view of recent discoveries

Between 1985 and 2007 overall nineteen human skulls dating to the Late Neolithic period were recovered at Kö?k Höyük, which lies within the borders of Bor, a district of the Ni?de Province in Central Anatolia. One of these skulls belongs to a child and the remainder to adult males and females. The plastered skulls may have been laid on or wrapped in mats and exposed either singly or in groups on a plaster surface inside the house. Among thirteen of these skulls the mouths, noses, eyes and ears were depicted with clay and painted with red ochre, while the remaining six were untreated. Two headless skeletons were also found in situ underneath the floor inside the house. One of these skeletons belongs to a child aged approximately 15–16 years old and the other belongs to an adult female. The modeled human skulls were encountered in the second and third cultural levels of the Late Neolithic period indicating that this characteristic mortuary practice lasted for quite a long time and likely disappeared by the Chalcolithic at Kö?k Höyük.     

Modern and early-middle Holocene shells of the freshwater mollusc Unio, from Çatalhöyük in the Konya Basin, Turkey: preliminary palaeoclimatic implications from molluscan isotope data

Carbon and oxygen isotope ratios in the shells of the freshwater Unio mollusc yield information on the isotopic composition of the water in which the shell was formed, which in turn relates to climatic conditions prevailing during the bivalves’ life span. Here we analysed shells from one modern Unio, from a modern lake shore in Anatolia, and 4 subfossil Unio shells from Çatalhöyük (dated between 7200 BC and 5000 BC, Neolithic and Chalcolithic periods). Sequential carbon and oxygen isotope analysis along the surface of the shells provides information on seasonal or shorter-term variability of lake waters during the lifetime of the organisms. δ¹⁸O values of the modern shell are consistent with it being collected from a dammed portion of the Seyhan River that does not undergo intensive summer evaporation. This is in contrast to many of the surface water bodies in Anatolia which suffer extensive evaporation in the arid summers. δ¹⁸O values of the subfossil shells from the Çatalhöyük middens indicate that the bivalves came from lakes which evaporated extensively during the summer months but were replenished by high winter rainfall, suggesting that the subfossil shells lived in relatively small lakes or ponds. Stable isotope analysis along the growth of freshwater bivalves is one of the few methods for investigating seasonal water fluctuations in the past. These results may alter current interpretations on the environment of Çatalhöyük during the Neolithic, although more work is needed to confirm these initial findings.     

Distinguishing Nemrut Dağ and Bingöl A obsidians: geochemical and landscape differences and the archaeological implications

Distinguishing the geochemically similar Bingöl A and Nemrut Da? peralkaline obsidians is a major challenge in Near Eastern obsidian sourcing. Despite abundant claims in the literature otherwise, this study reveals that Bingöl A and Nemrut Da? obsidians are distinguishable with adequate source sampling and highly accurate and repeatable data for geochemically important elements. Earlier research has endeavored to link a simple geochemical trend (peralkalinity) to specific locations at Nemrut Da?, but existing schemes to distinguish Bingöl A and Nemrut Da? obsidians cannot validly link compositional clusters to the landscape. This study demonstrates that additional elements are required to attribute artifacts to specific obsidian-bearing lava flows at the volcano. Limitations of this newly analyzed collection of geo-referenced Nemrut Da? and Bingöl specimens suggests caution is still warranted in sourcing peralkaline obsidians, but a few archaeological implications are clear. New sourcing results from Tell Mozan in northeastern Syria refute a widespread assumption that one can use maximal efficiency to deduce whether peralkaline obsidian artifacts originated from Nemrut Da? or Bingöl A. The ability to discern among these sources also enables inquiries into issues of cultural and technological preferences regarding these obsidians.     

Food and social complexity at Çayönü Tepesi,southeastern Anatolia: Stable isotope evidence of differentiation in diet according to burial practice and sex in the early Neolithic

The identification of early social complexity and differentiation in early village societies has been approached in the past most notably through the evaluation of rituals and architectural layouts. Such studies could be complemented by an approach that provides data about everyday behaviours of individuals. We took 540 human and animal bone samples for stable carbon and nitrogen isotope analysis from the Neolithic site of Çayönü Tepesi in southeastern Anatolia. The inhabitants at this site chose to bury their dead in two different ways at different times during its occupation: beneath the floors of their houses, but also inside a public mortuary building known as the Skull Building. This variation provides an opportunity using isotope methods to test whether there was evidence for structuring of daily activities (diet in this case) that might serve to reinforce this change in burial practice. We show that when the inhabitants of Çayönü Tepesi changed their architecture and operated different burial practices in conjunction, this coincided with other aspects of behaviour including socially-constituted food consumption practices, which served to reinforce social identities.     

An investigation of cortical bone loss and fracture patterns in the neolithic community of Çatalhöyük,Turkey using metacarpal radiogrammetry

Bioarchaeologists have conducted numerous studies on human skeletal remains using metacarpal cortical bone radiogrammetry. This method allows cortical thickness of the second metacarpal to be quantified. As a sensitive index of bone health metacarpal cortical thickness is evaluated in the context of functional adaptations, growth, ageing and bone loss in osteoporosis, as well as used as a reliable indicator of fracture risk. The focus of this study is an examination of the widely used calculation that expresses second metacarpal cortical bone values, followed by an examination of age and sex-related patterns of cortical bone loss and skeletal fragility fracture in a Neolithic archaeological skeletal sample from Çatalhöyük, Turkey. Using metacarpal radiogrammetry, 49 adult metacarpals (f = 27 m = 22) were examined. Data were collected for size variables, length (L) and total bone width (TW) as well as quantity variables, medullary width (MW) and cortical thickness (CT). These parameters were then used to calculate the widely used cortical index (CI) and two new indices expressing medullary width and cortical bone thickness in relation to length (medullary width index, MWI and cortical thickness index, CTI). The ratios were then used to explore age- and sex-related cortical bone loss and fragility fracture patterns amongst the inhabitants of Çatalhöyük. Çatalhöyük males and females demonstrate an inverse relationship where CTI decreases as age and MWI increase. Analyses indicate statistically significant age-related change in MWI amongst the oldest females. Despite age-related loss of bone, no typical fragility fractures are observed. We discuss the role of ageing and lifestyle factors at Çatalhöyük that may have been beneficial to skeletal health and a reduction in the risk of fragility fracture.     

Neutron Activation Analysis of Obsidian From Kalavasos-Tenta

Abstract

The small quantity of obsidian used by the Aceramic Neolithic occupants of Cyprus was imported, there being no source on the island.

The chemical composition, determined by neutron activation analysis, of six samples of obsidian from Kalavasos-Tenta indicates that they were derived from the central Anatolian, Göllü Da? (çiftlik: Group 2b) source. On the basis of chemical composition, obsidian from five Cypriot Aceramnic Neolithic sites has the same provenance. Our data suggest that the fragments we analyzed were not derived from a single core and, because obsidian occurs throughout the Aceramic period of occupation of kalavasos-Tenta, it appears unlikely that the 36 artifacts recovered from the site represent a one-time transfer of material. This suggests an enduring supply, and implies to us that the inhabitants of Kalavasos-Tenta were never completely isolated from the mainland.     

Origins of Specialization: The Ceramic Chaîne Opératoire and Technological Take‐Off at Vinča‐Belo Brdo,Serbia

This paper presents scientific analyses of Neolithic pottery from Miloje Vasi?’s 1930 –34 excavations at Vin?a‐Belo Brdo, which has long been a key site in south‐eastern European prehistory. Results show a series of changes in the chaîne opératoire of pottery production, both between the early Neolithic Star?evo and middle–late Neolithic Vin?a periods, and between Vin?a A and Vin?a B phases. Unlike in Star?evo assemblages, Vin?a pottery fabrics probably served specific functions, but cult objects (an anthropomorphic figurine and several prosopomorphic lids) were made locally using the same raw materials and technology used to make Vin?a fine ware. In contrast to the uniformity of Star?evo pottery technology, Vin?a pottery production was geographically diverse and evolved over time. Higher firing temperatures of Vin?a pottery apparently preceded the development of metallurgy by more than a century.     

Corporate kin-groups,social memory,and “history houses”? A quantitative test of recent reconstructions of social organization and building function at Çatalhöyük during the PPNB

It has been argued that the corporate kin-group was the main form of socioeconomic organization at the Turkish site of Çatalhöyük during the Pre-Pottery Neolithic B (PPNB). This hypothesis is linked to a claim of long-term repetitive patterning in the use of household space. Çatalhöyük's corporate kin-groups, it is suggested, would have been maintained by social memory, and social memory would have been created by the repeated rebuilding of houses with the same floor plan and by the burial of important members of the corporate kin-groups under house floors. This hypothesis been taken up by a number of authors in recent years. However, it is not clear how much confidence should be invested in the hypothesis as the use of household space at Çatalhöyük during the PPNB has not been subject to formal evaluation. With this in mind, we carried out a study in which we examined the relationship between continuity in house floor plans and the percentage of houses that contain burials. To assess the co-variation between these variables, we developed a GIS-based method of quantifying house wall continuity, and then subjected the resulting index and a number of other variables, including the percentage of houses that contain burials, to factor analysis. The results of the analyses do not support the hypothesis. The house-wall continuity index and the percentage of houses that contains burials load on different factors, which indicates that they do not co-vary through time. This is contrary to the predictions of the corporate kin-group hypothesis. Thus, claims that during the PPNB Çatalhöyük's occupants formed corporate kin groups that were maintained by social memory and “history houses” should be curtailed and interpretations built on this hypothesis should be viewed with suspicion.     

Regionale Wirtschaftsförderung und E-Commerce—Ergebnisse einer Untersuchung in Baden-Württemberg

Die Auswirkungen des Einsatzes moderner Informationsund Kommunikationstechnologien (IuK) werden oftmals unter dem Schlagwort der Globalisierung zusammengefaßt. IuK-Technologien stellen die technischen Voraussetzungen beispielsweise für die weitgehende Vernetzung von Unternehmen, für neue Formen der Arbeitsteilung und -kooperation.Im Fokus der wissenschaftlichen Diskussion um E-Commerce stehen Veränderungen auf globaler Ebene, die Frage nach den möglichen, raumwirksamen Veränderungen in den Regionen wird dagegen nur wenig diskutiert. Was aber bedeutet der Einsatz von E-Commerce konkret für Absatzmärkte, Kunden- und Lieferantenbeziehungen auf der regionalen Ebene? Besteht die Gefahr einer Schwächung insbesondere der mittelständischen, meist regional verankerten Betriebe oder bietet E-Commerce gerade für die kleineren und mittleren Unternehmen (KMU) die Chance eines Innovationsschubs? Ein Blick auf die regionale Ebene zeigt, daß hier zahlreiche Förderaktivitäten unternommen werden. Dies wirft Fragen auf: Welche Strategien sind bei dieser Förderung erkennbar? Wie geht die traditionelle Wirtschaftsförderung mit diesem für sie neuen Thema um?

Plants as material culture in the Near Eastern Neolithic: Perspectives from the silica skeleton artifactual remains at Çatalhöyük

Investigating plants used for building and craft activities is important for understanding how environments surrounding archaeological settlements were exploited, as well as for considering the social practices involved in the creation and use of plant objects. Evidence for such plant uses has been observed at many Near Eastern Neolithic sites but not widely discussed. Survival may occur in a number of ways, including as impressions in clay, and as charred or desiccated macroremains. Another, less well-known, way in which plant artifacts can be found is as silica skeletons (phytoliths). Formed by the in situ decay of plants, their analysis may tell us about taxa exploited, and locations in which plant artifacts were used or discarded. At Çatalhöyük, an abundance of silicified traces of plants used in building materials and for craft activities survive, and are found in domestic and burial contexts. Their analysis demonstrates the routine use of wild plants, especially from wetland areas, for basketry (mats, baskets and cordage) and construction, as well as the secondary use of cereal husk chaff in certain types of building materials. The numerous finds suggest that plant-based containers played an important role as an artifactual class, even after the adoption of early pottery.     

Petrographic and geochemical investigations of the late prehistoric ceramics from Sos Höyük,Erzurum (Eastern Anatolia)

Ceramics from the late prehistoric periods at Sos Höyük, in Eastern Anatolia, located along a thoroughfare that connects the Trans-Caucasus, Iran and central Anatolia, were subjected to petrographic and X-ray fluorescence analysis in order to characterise the clay groups, with a view to determining provenance and production patterns. Dominated by Kura-Araxes Ware, the data from the sequence at Sos Höyük were compared with the previous studies from the neighbouring regions to understand commonalities in pottery production. The analyses reveal a local production of vessels, most probably for household use. Although Sos Höyük potters shared similarities in the procurement pattern of raw clays and production technique with their neighbours, differences can be also recognized.     

The combined use of oxygen isotopes and microwear in sheep teeth to elucidate seasonal management of domestic herds: the case study of Çatalhöyük,central Anatolia

This paper presents and tests a model designed to investigate how off-site herd management developed in settled pre-historic societies. The model is constructed from data collected from traditionally raised local sheep, acting as an interpretive link to published data. The modern comparator was small, but plausible results allow modelling of the archaeological data to be explored. Birth seasonality and herding location are identified through modelled patterns in oxygen isotope data in tooth enamel, and diet just before death by microwear in the same tooth. In combination, these allow aspects of seasonal management of breeding, fallow and slaughter herd sections to be interpreted. Novel practices are discussed in comparison local wild sheep ethology. The case study is Neolithic Çatalhöyük (7400–6200 cal BC) in central Anatolia. Its location provided the opportunity for different parts of the landscape to be used for herding, although choice might have been socially constrained. Data are taken from 72 specimens; the results suggest settlement-wide preference for a suite of practices that kept herds within a day of the settlement and that maintained breeding cycle synchrony with optimal resource availability. Chronological analysis suggests birth season manipulation was tried but rejected, whilst hay or cereal fodder was introduced and became increasingly important. It is argued that herding was probably on dedicated pasture on the arable fringes rather than in closer integration on ‘garden plots’, as there is no evidence of field-edge weed diets and little evidence of adjusting the birth season to accommodate the crop cycle.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.     

Wild at heart: Approaching Pitted Ware identity,economy and cosmology through stable isotopes in skeletal material from the Neolithic site Korsnäs in Eastern Central Sweden

The Middle Neolithic Pitted Ware Culture on the Baltic Sea islands comprised a common identity distinguished, in part, by an almost exclusively marine diet. Based on evidence from the first stable isotope analysis on Pitted Ware skeletal material from the Eastern Central Swedish mainland, we suggest that this identity was shared by PWC groups in the archipelago of the west side of the Baltic. Fifty-six faunal and 26 human bone and dentine samples originating from the Pitted Ware site Korsnäs in Södermanland, Sweden were analysed, and the data clearly shows that the diet of the Korsnäs people was marine, predominantly based on seal. The isotope data further indicate that the pig bones found in large quantities on the site emanate from wild boar rather than domestic pigs. The large representation of pig on several Pitted Ware sites, which cannot be explained in terms of economy, is interpreted as the results of occasional hunting of and ritual feasting on wild boar, indicating that the animal held a prominent position, alongside seal, in the hunting identity and cosmology of the Pitted Ware people. Further, eleven new radiocarbon dates are presented, placing the Korsnäs site, with a large probability, within Middle Neolithic A.     

Continuity and change in pottery manufacture between the early and middle Neolithic of Romania

This paper provides the first scientific comparison between pottery production in the early Neolithic Star?evo-Cri? and middle Neolithic Vin?a cultures of south-eastern Europe. The author investigates whether Star?evo-Cri? pottery technology was transmitted to the succeeding Vin?a culture, which in other respects was more complex and technologically advanced. The study compares pottery production at two sites, in different regions of Romania, which were occupied in both periods. Samples of 102 pots from the Star?evo-Cri? and Vin?a phases at Par?a, located in Romanian Banat, and Miercurea Sibiului Petri? in Transylvania, were analysed petrographically and geochemically. There are only minor differences found in the pottery technology between the two sites within each phase, but there were significant changes in pottery technology between the Star?evo-Cri? and Vin?a cultures. These changes are more subtle than might have been expected, however, given the rapid developments in other aspects of material culture.     

DIGGING PITS AND MAKING PLACES AT UĞURLU DURING THE SIXTH MILLENNIUM BC

The site of U?urlu on the island of Gökçeada (Imbros) is the earliest known Neolithic settlement within the Aegean Islands (c.6800–4500 cal. BC). In total, 37 pits, associated with a rich variety of artefacts as well as human and animal bones were excavated in the Late Neolithic and Early Chalcolithic levels of the site (c.5900–4500 BC). The pits belonging to the early sixth millennium BC levels of U?urlu were small and located within the houses that seem to have gone through multiple episodes of house destruction and renovation rituals. During the late sixth millennium BC, this area became the focus of extensive pit‐digging activity, when large pits involving rich variety of artefacts were set within the courtyard of a special building (Building 4). Among the pits, a collective human burial pit (P188) incorporating the remains of 11 individuals and another pit (P52) involving a partial human skeleton were also found. From a comparative point of view, the construction techniques of these pits, their spatio‐temporal relations as well as their associated archaeological artefacts resemble the Anatolian and Near Eastern Neolithic practices of house destruction and renovation cycles, which are activities related to the ancestor cults of the region. We argue that all of these practices reflect public events during which social relations were negotiated through the agency of place. The differences observed during the sixth millennium BC at U?urlu reflect the changing concepts of place and society in the immediate aftermath of the Neolithic Process, when interactions with the Balkans as well as the Aegean intensified in this region.
