Removal of natural organic dyes from wool–implications for ancient textile provenance studies

Ancient wool textiles recovered from archaeological sites are in many cases originally dyed with natural organic dyestuffs from vegetable sources. These include among others woad (Isatis tinctoria L.), weld (Reseda luteola L.), and madder (Rubia tinctorum L.). These dyestuffs could be a threat to the use of the strontium isotopic system as a tracer for provenance studies of ancient wool, because they could potentially contaminate the signature of the textile's raw material. We present a novel method which allows for efficient removal of organic dyestuffs in wool prior to strontium isotopic analysis. Our method is based on an oxidative release of the dyestuff constituents by ammonium peroxodisulfate [(NH₄)₂S₂O₈] solution, combined with hydrofluoric acid (HF) that has shown to effectively remove/dissolve adhering dust micro-particles. Our multi-analytical results show that such a pretreatment is capable of removing >98% of the originally present organic dyestuffs without significantly destroying the wool structure. The strontium isotopic ratios of the residual wool fraction after the application of the pretreatment are sensitive to the origin and, therefore, can be used as tracers for the provenance of the raw material. We propose to apply this method to ancient wool textiles in which positive identification of organic dyestuff constituents by High Performance Liquid Chromatography (HPLC) was made.     

The Huldremose Iron Age textiles,Denmark: an attempt to define their provenance applying the strontium isotope system

Archaeological textiles recovered on two occasions from the Huldremose bog, Denmark, represent some of the best preserved and complete garments from the Danish Iron Age (500 BC–AD 800). In order to address the question regarding the provenance of the textile's raw material, we applied a recently developed method based on strontium isotopes to wool and plant fibres from these ancient garments. Textile plant fibres from Huldremose I find are of non-local provenance, whereas the wool from which the garment was made stemmed from sheep grazing on glaciomoraine soils developed on Cretaceous–Tertiary carbonate platform sediments widely found in Denmark. The Huldremose II find consists of an unusually large and well preserved garment, which is composed of wool from at least three different provenances. One source is again local, whereas the other two sources, characterized by elevated ⁸⁷Sr/⁸⁶Sr ratios, are compatible with geologically older (Precambrian) terrains which are typical for Northern Scandinavia, e.g. Norway or Sweden. Our study suggests that wool and plant fibres were either traded or brought as raw materials for textiles more commonly and over longer distances than previously assumed.     

The Kingdom of Kush: An African Centre on the Periphery of the Bronze Age World System

The Kingdom of Kush flourished in northern Sudan between 2000 and 1500 BCE. During this period, the capital Kerma emerged as a major economic and political centre in the Nile Valley. After a short review of the application of world system theory and centre-periphery perspectives in archaeology, the author proceeds to a presentation of the Bronze Age societies in northern Sudan and their wide-reaching trade relations. A central argument is that an incentive for the rise of the Kingdom of Kush was its intermediate position in long-distance trade between the north and the south. The article concludes with a discussion of Kush as a centre on the periphery of the so-called Bronze Age World System in Afro-Eurasia.     

Le principe de circulation et l'échec de la mythologie transeuropéenne

We have sought to identify an aspect of the repression of Enlightenment cosmopolitanism complementary to the creation of national identities in XIX^th-century Europe and the intervening war period. The idea of a common civilization would be maintained by the reciprocal capacity of translating national languages, because of their Indo-European common origins. The utopia of the language would replace the material route of the Enlightenment. It is the failure of the construction of European Indianist myth and not its success which explains the ideological diverting of the relations between language and nation. The missed promotion of the Gypsy language in the academic world illustrates this failure perfectly. After the First World War, the transformation of the principle of nationalities in ethnopolitics removed even the memory of this common ambition.     

Changing recess geographies: children’s perceptions of a schoolyard renovation project promoting physical activity

ABSTRACT

Insights into children’s perceptions of their changing recess geographies are absent. The current paper provides qualitative evidence from 5 renewed schoolyards by investigating children’s perceptions of their new schoolyards. Ten focus groups (2 at each school) including go-along interviews were conducted, in total 57 4 to 8 graders (28 girls). The functional aspects of the altered child–environment relationship were assessed using Gibson’s concept of affordance, and changes in the meanings ascribed to the schoolyards by the children were studied by engaging a concept of place. Our findings reveal that schoolyards offering multiple potential affordances for physical activity seem more likely to engage a broader group of children in recess physical activity. The analysis, however, could point to a difference between places designed for children’s play and places where children actually play. To optimise actualisation of the potential affordances for recess physical activity, involving children throughout intervention planning and decision-making is crucial.
