War Shields of the Torricelli Mountains,West Sepik Province,Papua New Guinea

ABSTRACT The usefulness of the term ‘ethnolinguistic group’, as a construct suggesting that ‘differences in language automatically translate into differences in culture’, has been questioned by Welsch, Terrel and Nadolski (1992). Not many researchers would insist on the term ‘automatically’, but would nevertheless support an argument for a strong correlation between material culture and language. As a contribution to this debate, we discuss two types of wood shields of the Torricelli Mountains (one of which is being identified for the first time) and pigskin shields to the south of the Torricellis, their use, and the details of the carved designs of the wood shields. The results of our analysis provide limited support for the correlation of material culture and language but highlight the need for analysis of material culture based on reliable data for a large number and wide range of artefacts, from defined regions, presently held in museums and private collections worldwide.     

Conservation of knife handles from the Elizabethan warship Makeshift

Knife handles from an Elizabethan Warship, probably the Makeshift (1592), have been conserved by a new technique, supercritical drying. Many of the knife handles are complex composites containing wood, cloth, leather, iron and copper alloys, and the technique has allowed these to be conserved as single units, where alternative techniques would have damaged or destroyed one or more of the component parts. A further advantage for using supercritical drying is that it is a minimum of four times faster than freeze-drying. A total of eleven knife handles have been conserved by the technique, with minimal loss of surface detail. The results compare favourably with those of waterlogged wood samples conserved by freeze-drying.     

A flock of sheep,goats and cattle: ancient DNA analysis reveals complexities of historical parchment manufacture

Parchments comprise one of the most common and valuable sources of archaeological and historical data. Previous studies have shown that parchment also preserves genetic data. These data could be valuable for population studies, to understand past animal husbandry, the development of breeds and varieties and to comment on the provenance of parchments. To improve our understanding of DNA contained in parchments, we analysed genetic data, including both mitochondrial and autosomal loci, from 18th to 19th century English parchments which stable isotope analysis had indicated were well-preserved. DNA results were unexpected. All but one of the parchments produced multiple sequences matching several different species. Ion beam analysis ruled out surface treatments of the parchments (including ink and animal glues) as the origin of these multiple sequences. Our results suggest that the DNA content of parchment is more complex than previous research has suggested and that multiple stages of parchment manufacture, treatment and storage are preserved in parchment DNA extracts.
