A New Method For Combining Lead Isotope and Lead Abundance Data to Characterize Archaeological Copper Alloys*

We present a new methodology for interpreting lead isotope data from archaeological copper alloy objects. It is not based on the conventional isotope ratio biplots, which were originally devised to allow the calculation of the geological age of the lead mineralization, but is derived from isotope mixing models, more often used for presenting strontium isotope data. We illustrate the method by reworking published data on Sardinian Nuragic oxhide ingots and copper alloy artefacts. While we confirm the consensus assumption that the oxhide ingot fragments found on Sardinia are isotopically consistent with Cypriot copper ores (although we see no isotopic reason to favour only Apliki, as originally suggested), we also show that there is evidence for mixing between local and ingot copper in some objects, which was previously not detected. More broadly, we suspect that the apparent mismatch between some source allocations for copper drawn from isotope geochemistry and the rest of the archaeological data in some cases might be due to mixed isotopic signals being incorrectly assigned to a specific source, and suggest that the method presented here will reduce the chances of this happening.     

A little souvenir: the Marquess and the Mycenaean columns

This is a study of change over time, both in attitudes to objects, and in the manner of their collection. The example of a pair of columns from a Mycenaean tholos tomb, the so-called 'Treasury of Atreus' at Mycenae, serves as a point of departure for discussion of the value of material culture in the context of archaeology's emergence as a discipline.     

The Rise and Fall of ‘Internally Displaced People’ in the Central Peruvian Andes

This article analyses the possible effects of the introduction of the category of ‘internally displaced people’— IDP — in the context of violent conflict in central Peru. It gives an account of the ways in which the IDP category has been introduced and appropriated by local NGOs, people affected by violent conflict and displacement, and by the governmental organization, PAR, set up to facilitate return and repopulation after the declared end of the armed conflict. The category has facilitated and given leverage to a national organization of IDPs. However, the agencies and programmes that work in support of IDPs tend to regard existing mobile livelihood practices as an impediment for advocacy and longer‐term development strategies. This article suggests that, instead of considering displacement (and return) as an absolute break with the past, a focus on networks and mobile livelihoods may be a better way to help people affected by violent conflict to move beyond emergency relief.     

The maritime landscape of Kilwa Kisiwani and its region,Tanzania, 11th to 15th century AD

East African coastal archaeological research has traditionally concentrated on the stone towns. In contrast, this study adopts a maritime cultural landscape approach by examining one of those towns, Kilwa, in its wider setting towards the peak of its economic success. Using archaeological evidence derived from coastal and inter-tidal survey and excavation, it identifies the environmental advantages of Kilwa′s estuarine location and resources that are exploited by a series of settlements providing marine produce and construction materials. The maritime approaches to the town also provide the context for a cultural display of religious allegiance and power through the symbolism of conspicuously sited mosques and a more perplexing series of causeways. Knowledge of the wider integrated coastal environment is seen as key to understanding the culture and economy of the region.
