Bioarchaeological studies have found that, in general, the adoption of agriculture is associated with deteriorating oral health, most frequently manifested as an increase in the prevalence of dental caries. However, compared to other regions of the world, bioarchaeological studies focusing on prehistoric Europe have produced more variable results, with different populations experiencing deteriorations, improvements, and stasis in oral health. This study assesses the oral health of individuals of the Tripolye culture buried in Verteba Cave, Ukraine, within the context of the transition to agriculture in Eastern Europe. We compare the rates of dental caries between Tripolye farmers with earlier hunter-fisher-gatherers from Ukraine. The Tripolye were found to have carious lesions on 9.5 per cent of teeth, while the hunter-fisher-gatherers were found to be universally free of carious lesions. A Fisher's exact test demonstrates that this difference is statistically significant, supporting the model that the transition to agriculture was detrimental to oral health in prehistoric Ukraine. This could be related to the manner in which grain was processed by the Tripolye and the needs of their relatively population-dense society.

One hundred and sixty hypogea have been discovered in the Paris Basin, concentrated in the south-west part of the Marne department. Radiocarbon dates and archaeological artefacts indicate their construction and use were a phenomenon limited to the Late Neolithic 2, currently estimated as 3350–3000 cal BC. Re-examination of the human skeletal remains, notably those from Les Mournouards II, enables us to improve our understanding of the practices involved in these collective burials, particularly aspects of individual selection and distribution. Age, sex, and social status determined the burial location between and within the artificial caves. Burial positions characterized two groups of hypogea. However, in both groups, most female individuals were buried along the left wall of the monuments, on the same side as the collective grave goods and carved female figures sometimes discovered in the anterooms. The nature and distribution of personal material reflect the existence of particular statuses for some individuals. The burial principles reveal a relative conservatism guaranteeing distinction between individuals of different lifetime statuses. Several competing strategies sought to preserve, in death, this social order. The mortuary practices, then, reflect a codified social organization for a Paris Basin group of the later fourth millennium BC and a burial practice that was less ‘collective’ than might have been imagined.

This paper considers the early copper and copper-alloy metallurgy of the entire Alpine region. It introduces a new approach to the interpretation of chemical composition data sets, which has been applied to a comprehensive regional database for the first time. The Alpine Chalcolithic and Early Bronze Age each have distinctive patterns of metal use, which can be interpreted through changes in mining, social choice, and major landscape features such as watersheds and river systems. Interestingly, the Alpine range does not act as a north-south barrier, as major differences in composition tend to appear on an east-west axis. Central among these is the prevalence of tin-bronze in the western Alps compared to the east. This ‘tin-line’ is discussed in terms of metal flow through the region and evidence for a deeply rooted geographical division that runs through much of Alpine prehistory.

In the second millennium cal BC, a new metal conquered Europe: the alloy of copper and tin that improved the quality of tools and weapons. This development, we argue, initiated a framework for a new political economy. We explore how a political economy approach may help understand the European Bronze Age by focussing on regional comparative advantages in long-distance trade and resulting bottlenecks in commodity flows. Links existed in commodity chains, where obligated labour and ownership of resources helped mobilize surpluses, thus creating potential for social segments to control the production and flows of critical goods. The political economy of Bronze Age Europe would thus represent a transformation in how would-be leaders mobilized resources to support their political ends. The long-distance trade in metals and other commodities created a shift from local group ownership towards increasingly individual strategies to obtain wealth from macro-regional trade. We construct our argument to make sense of available data, but recognize that our model's primary purpose is to structure future research to test the model.

In Roman imperial times, metallurgy reached a high degree of specialization and complexity. The use of iron extended even to building technology, leading to some very particular results, achieving a sophisticated mastery of the technology with a complete understanding of metal properties, in a social and economic context characterized by large financial resources and a high level of creativity applied to architectural projects. A still unpublished device was found in the construction of several floors in the Villa of Giulia, Augustus' daughter, in Ventotene (Italy). In the thermal area, the concrete floors of the bath tubs are supported by an iron grid held in place by vertical iron posts strongly fixed in the underfloor, allowing both widespread hot air circulation and support for superimposed loads. A curvilinear metal grid supported by metal hooks was also used to obtain a tile-line vault, creating an interspace for the circulation of hot air in calidaria; a careful analysis of the remains of two vaulted systems in Villa Adriana, Tivoli (Italy), allows a clear reconstruction of this device. The building process was difficult and complex, requiring careful planning and great accuracy in execution. However, after nearly a century of experimentation, it is possible to propose the hanging ceiling built over the calidarium of the Baths of Caracalla in Rome as the most imposing example of the grid system ever realized.

This paper presents the results of the use of a minimally destructive biomolecular technique to explore the resource networks behind one of the first specialized urban crafts in early mediaeval northern Europe: the manufacture of composite combs of deer antler. The research incorporates the largest application of species identification by peptide mass fingerprinting (ZooMS) to a mediaeval artefact assemblage: specifically to collections of antler combs, comb manufacturing waste, and raw antler from Ribe, Aarhus, and Aggersborg. It documents the early use of reindeer (Rangifer tarandus) antler, from the 780s AD at the latest, presenting the earliest unambiguous evidence for exchange-links between urban markets in the southern North Sea region and the Scandinavian Peninsula. The results demonstrate that the common conceptual distinction between urban hinterlands and long-distance trade conceals a vital continuity. Long-range networks were vital to urban activities from the first appearance of towns in this part of the world, preceding the historically documented maritime expansion of the Viking Age. We consequently suggest that urbanism is more appropriately defined and researched in terms of network dynamics than as a function of circumscribed catchment areas or hinterlands.
