In this paper we explore the potential use of ergosterol (5, 7, 22-ergostatrien-3β-ol) as a possible biomarker for yeast and alcohol fermentation, applying the analytical technique previously used routinely in Swedish archaeology for the analysis of lipid residue in prehistoric pottery. Taking note on the connection between brewing, baking and agriculture the frequency of vessels showing gas chromatography mass spectrometry traces of this compound in lipid residues from a clearly agricultural Bronze Age/Early Iron Age population was compared with the same signal in a clearly non-agricultural Neolithic foragers pottery population. The result shows a small but statistically significant difference between the two populations, indicating a connection between the presence of ergosterol in lipid residues from pottery and agriculture. The results are also discussed in terms of varying cleanliness, degradation, deposition conditions and contamination. Suggestions for future research include the use of a more sensitive analytical protocol in order to improve detection limits and to include materials from clear agricultural Neolithic vessel populations. 相似文献

A growing recognition of the vital role that built space plays in social reproduction has created a need for analytical methods and interpretive frameworks with which to investigate this relationship in archaeological datasets. I address this by developing an integrative approach that emphasizes the role of the built environment as the context for interactions through which social structures are created, transformed and reproduced. This approach uses access analysis to examine how buildings structure patterns of movement and encounter that allow social actors to engage in or avoid particular forms of interaction. With its focus on the topological properties of built space, however, access analysis does not take adequate account of a building’s symbolic aspects, especially architectural characteristics and furnishings that social actors mobilize in the creation of meaningful contexts for interaction. I therefore integrate access analysis with an examination of how built environments encode meanings and nonverbally communicate them to inhabitants and visitors, potentially influencing their actions and interactions. The integrative approach allows determination of probable contexts for various types of social interactions during which social identities could be displayed, negotiated and reified. I conclude by demonstrating the potential of this approach with an analysis of the monumental Ashlar Building from the Late Bronze Age (c. 1650–1100 BC) site of Enkomi, Cyprus. 相似文献

The origins of raw glass used to fashion Mycenaean beads were explored using trace elements analyzed by laser ablation ICP-TOFMS. The use of this minimally destructive technique for the in-situ analysis of these beads was ideal given that the material is exceedingly rare and thus too sensitive to make use of traditional micro-sampling (e.g., by scalpel). A wide range of trace elements were measured to compare these Greek glasses to other Late Bronze Age glass coming from Egypt and Mesopotamia. Of the eleven beads analyzed, four blue glasses colored with cobalt and two blue/green glasses colored with copper have trace element compositions consistent with an Egyptian origin of manufacture. The other five of the glasses, all colored with copper, were found to conform to the composition of Mesopotamian glass. These data are the first to demonstrate direct and clear evidence for the trade of raw glass to the Mycenaean states. 相似文献

In this paper, analyses of some unusual slag samples from the prehistoric site of Tepe Hissar in northeastern Iran are presented. These slags are the remains of a five-thousand-year-old pyrotechnological process that produced speiss, a quasi-metallic material usually formed as an accidental by-product of copper or lead smelting. We argue that the “speiss slags” from Tepe Hissar suggest the intentional production of iron–arsenic alloy (“speiss”) in prehistory. Why the Tepe Hissar metalworkers produced speiss is a question that requires further investigation, but our preliminary assessment suggests that it was to provide arsenic as an alloying component for arsenical copper, the preferred copper alloy during much of the Early Bronze Age in Iran, and widely used across the ancient world. This recognition significantly advances our understanding of the early stages of metallurgy in the Old World. 相似文献

Neutron diffraction (ND) analyses of ancient metals show that this method is capable of detecting differences in the inner composition and microstructure of ancient metal objects. Here, ND measurements were conducted on two ‘eye shaped’ axes from the end of the 3rd-beginning of the 2nd millennium BC. The objects were excavated from the ancient cemetery of ‘Enot Shuni' Israel; one is made of bronze and the other of silver. Both artefacts are rare finds, with the silver axe unique in the archaeology of Israel, and therefore had to be analysed locally. For that purpose, a newly assembled diffractometer (KARL) at the IRR-1 of the Nuclear Research Centre (Soreq, Israel) was used. ND measurement on the bronze axe revealed the existence of an α-phase with a range of Cu/Sn ratios (Cu–Sn solid solutions) and some amount of a δ-phase (intermetallic compound of Cu and Sn). The silver axe ND pattern shows the existence of an α-phase (Ag–Cu solid solution) and some amount of copper metal. Our ND data are discussed in comparison with XRF surface measurements and thermal neutron radiography. The results are shedding more light on the in-depth material composition profile, as well as on the objects’ structural and compositional affinities, and help to better understand the production processes and assist in conservation decisions. 相似文献

Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is applied to the study of four samples of opaque glass of Late Bronze Age date. The technique is uniquely capable of identifying compositional heterogeneity at a sub-micron resolution within the crystalline opacifiers dispersed through homogeneous glass matrices. It is shown that this provides crucial information on the possible raw ingredients of the opacifying inclusions used, and has the potential for highlighting regional variations in the production technology involved in creating different colours of opaque glass. 相似文献

Excavations at Cladh Hallan, a Bronze Age-Iron Age settlement on South Uist in the Outer Hebrides off the west coast of Scotland, revealed the skeletons of two adults, a sub-adult and a child buried beneath the foundations of three roundhouses. Osteological and isotopic evidence has shown that the male adult skeleton is a composite made up of parts of at least three different individuals. To test the hypothesis that the female skeleton was also a composite we examined ancient DNA from four of its components: the skull, mandible, right humerus and right femur. Seven polymerase chain reactions (PCRs) were attempted, these covering positions 15,996–16,420, 16–132 and 232–368 of the mitochondrial DNA hypervariable I and II regions. Three PCRs were successful for each sample and a total of 55 sequences were obtained from the cloned products. After exclusion of possible contaminating sequences, the remaining 34 were compared. It was concluded that the mandible, humerus and femur come from different individuals. Insufficient data were obtained to draw conclusions regarding the origin of the skull. The presence of two composite skeletons at Cladh Hallan indicates that the merging of identities may have been a deliberate act, perhaps designed to amalgamate different ancestries into a single lineage. 相似文献
