Archaeomagnetic Dating of Pyrotechnological Contexts: a Case Study for Copper Smelting Sites in the Central Timna Valley,Israel

This study is focused on establishing age constraints for several copper slag deposits at the centre of the Timna Valley (Israel) via reconstruction of their ancient geomagnetic intensities as recorded by the individual slag samples at the time of their formation. The results show a correlation between the location of the slag deposits (labelled as individual ‘mounds’ in our survey) and their inferred ages, reflecting varying socio‐economic and political dynamics in the region. While the slag mounds found at the unprotected foothills represent a variety of dates (mostly Early Islamic), the slag mounds on the hilltops are chronologically constrained to the early Iron Age (late 11th to 10th centuries bce ), supporting the idea for a need for protection during this period. Furthermore, in comparing the new data with previous archaeomagnetic studies from Timna, we can assert the existence of simultaneous copper production at the archaeological Sites 30, 30a and 34. This gives further support to the claim of intense smelting in the central Timna Valley during the early Iron Age. Finally, this project demonstrates the potential of archaeomagnetic experiments to provide chronological insights, and their particular advantage in addressing pyrotechnology‐related cases.     

Dietary reconstruction in Migration Period Central Germany: a carbon and nitrogen isotope study

This study presents bone collagen carbon and nitrogen isotope data from the Migration Period cemeteries (fifth/sixth century AD) of Obermöllern and Rathewitz in Central Germany. The human average δ ¹³C ratios of ?19.8?±?0.3 ‰ and δ ¹⁵N ratios of 9.6?±?0.9 ‰ (n?=?43) reflect a mixed diet in a temperate C3-based ecosystem without significant difference between the two sites. The average offset between human and faunal δ ¹³C and δ ¹⁵N values indicates a significant contribution of plant food to the human diet that has different isotope ratios from the forage of the animals. It furthermore suggests the influence of land management on the δ ¹⁵N values. One adult male from Obermöllern stands out due to his elevated nitrogen isotope ratio, body height, grave goods, and burial position. The collagen isotope data of this study are comparable with data from other central European sites and confirm rather stable communities with moderate variation in the environmental conditions of arable land.     

Two Traditions of Bronze Age Burial in the Stonehenge Landscape

A study of the size of round barrows in relation to their position in the Stonehenge landscape allows us to define two types of mound, here termed 'Conspicuous' and 'Inconspicuous'. Conspicuous barrows are large and prominently located, whilst inconspicuous barrows are smaller and less strikingly placed. Inconspicuous barrows were associated mainly with funerary urns and were constructed throughout the Early and Middle Bronze Ages. Conspicuous barrows contain a wider range of grave goods and were mainly built in the later part of the Early Bronze Age. The Conspicuous barrows were impressive features of the prehistoric landscape and may have been built there because of the long-established significance of some of the local monuments, including Stonehenge itself. They contain exotic grave goods and could have been the burial places of a wider population. By contrast, the Inconspicuous barrows appear to be associated with settlement areas. They contain a range of ceramic grave goods which extend throughout the Early and Middle Bronze Ages and may have been built by the people who were living in the area. The latter tradition is the longer lived and retained its importance into the Middle Bronze Age when more conspicuous mounds were no longer built.
