A large systematic dye investigation of prehistoric Danish and Norwegian bog textiles was carried out using high performance liquid chromatography with photo diode array detection. After the selection of the most suitable protocol for dye extraction and HPLC analysis for this specific group of archaeological samples, the second part included the characterisation of the dyes detected in the whole series of the Early Iron Age textiles and the interpretation of the dyeing technology. Natural organic dyes were found from the three main categories of natural dyes, hence throwing new light on the use of biological dye sources in Early Iron Age Scandinavia. The results clearly indicate that most Scandinavian peat bog textiles originally were dyed and that already during the 1st millennium BC, the populations in Scandinavia were familiar with the dyeing technology. 相似文献

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. 相似文献

Expressions connected to friendship and brotherhood were a prominent part of letter‐writing in the 16th century. They did not necessarily describe the true nature of a given relationship, but can rather be seen as a strategy, as a means to refer to shared values and norms related to friendship. Among noblemen, appealing to friendship was the main way of justifying requests. This reveals a connection between the rhetoric of friendship and power. Along with an emotional bond or a supporting network, friendship can be examined as a cultural ideal, which could be utilized rhetorically to produce and exercise power. 相似文献

This article argues that regional planning is dominated by two conflicting discourses that have different principles of involvement: the discourse of partnerships and the discourse of broad participation. These discourses and principles are not easy to reconcile in practice. On the basis of studies in the literature and a comprehensive case study, this article discusses how these conflicting discourses in regional planning challenge democratic norms, and how this problem is dealt with by the regional political leadership. The article shows that the use of meta-governance strategies and broad arenas of participation might be used in this respect, for example, by constantly having a focus on maintaining democratic anchorage when partnerships are used in regional planning processes. 相似文献

During archaeological excavations in central Tallinn, Estonia, many fish bones were collected among other archaeological finds. As these were salvage excavations conducted under limited time and cost restraints, only a very small part of the removed soil could be examined for fish bones. In such hasty conditions, the only option was to take soil samples from selected areas and carry out water sieving in the laboratory. This procedure resulted in the recovery of a variety of fish remains. Also, a previous conclusion that only large fish were captured is re-evaluated. This paper focuses on two recently excavated medieval sites in Tallinn: Tartu Road 1 and Vabaduse Square. In Vabaduse Square, a Late Neolithic settlement was also discovered under the medieval layers. The analysis of the three different assemblages of fish bones from the two sites, which were collected by somewhat different methods, contributes to our knowledge on fishing and fish consumption in Tallinn's past. 相似文献

The use of wool derived from sheep (Ovis aries) hair shafts is widespread in ancient and historic textiles. Given that hair can represent a valuable source of ancient DNA,
wool may represent a valuable genetic archive for studies on the domestication of the sheep. However, both the quality and
content of DNA in hair shafts are known to vary, and it is possible that common treatments of wool such as dyeing may negatively
impact the DNA. Using quantitative real-time polymerase chain reaction (PCR), we demonstrate that in general, short fragments
of both mitochondrial and single-copy nuclear DNA can be PCR-amplified from wool derived from a variety of breeds, regardless
of the body location or natural pigmentation. Furthermore, although DNA can be PCR-amplified from wool dyed with one of four
common plant dyes (tansy, woad, madder, weld), the use of mordants such as alum or iron leads to considerable DNA degradation.
Lastly, we demonstrate that mtDNA at least can be PCR-amplified, cloned and sequenced from a range of archaeological and historic
Danish, Flemmish and Greenlandic wool textile samples. In summary, our data suggest that wool offers a promising source for
future ancient mitochondrial DNA studies. 相似文献

Vrouw Maria, a merchant vessel sailing from Amsterdam to St Petersburg in 1771, ran aground in the northern Baltic Sea. Her cargo included Dutch works of art bought by Catherine the Great. The wreck was located in 1999, 41 m deep. This study aims to understand environmental factors and physical stresses affecting the wreck, using three different approaches—studying the wreck as an artificial reef; describing the conditions inside the wreck; and measuring the physical stresses caused by currents. The methods applied were biological, archaeological, hydrological, geological and physical. The data will be a basis for further monitoring. © 2010 The Authors 相似文献

This study presents the results of 44 new 14C analyses of Danish Early Iron Age textiles and skins. Of 52 Danish bog finds containing skin and textile items, 30 are associated with bog bodies. Until now, only 18 of these have been dated. In this paper we add dates to the remaining finds. The results demonstrate that the Danish custom of depositing clothed bodies in a bog is centred to the centuries immediately before and at the beginning of the Common Era. Most of these bodies are carefully placed in the bog – wrapped or dressed in various textile and/or skin garments. The care with which these people were placed in the bog indicates that they represent a hitherto unrecognised burial custom supplementing the more common burial pratice for this period. 相似文献
