Oggestorp, near J. onk. oping in southern Sweden. The sediment filling the interstices between stones in a wall and a clearance cairn is assumed to have been light exposed during or before construction, and we anticipated that these fill samples were likely to be incompletely bleached, so that the smallest doses would be the most relevant. However, any reworking of the structures, or even later aeolian events, could emplace a small fraction of younger materials, and so there were also likely to be some grains with substantially smaller doses. The dose distributions from such fill samples have been studied using both small aliquots and individual grains of quartz. We present preliminary construction ages for a stone wall and cairn based on these dose distributions, and compare these with independent age constraints derived from OSL ages of associated heated stones and aeolian sand, and from the other archaeological evidence.

In this article a model of how knives can be analysed is presented. The model is based upon characteristics that are important when discussing the use value of the knife as well as its symbolic value. Certain characteristics have been identified as important on basis of practical forging and knifemakery. Physical characteristics such as the design of the tang, the knives length and how its edge is designed is important information when discussing to what purpose the knife was manufactured. The material of the blade gives information about both the smith and how the knife might have been used. Two different materials can be used, these are iron and steel. Steel is iron with a carbon content of 0,3-2%. Steel has different use values than iron. It may be tempered and therefore an edge made out of steel remains sharp longer than a similar edge made out of iron. Iron and steel can also be combined. The social meaning of a k...

In this article we discuss the dating and interpretation of a field wall in Öggestorp, situated on the northern rim of the southern Swedish uplands in the province of Småland. Öggestorp is a complex archaeological site dating from the early Iron Age (500 BC to AD 550). The site was also used for various forms of agriculture during the Middle Ages and in early modern times, a fact which complicates the dating and the interpretation of the agrarian features. We discuss the possibility and practical issue of dating agrarian sediments by optically stimulated luminescence (OSL). By combining OSL and other methods, a reliable estimation of age can be established. The paper also deals with the possible implications of the OSL-method in relation to the current state of knowledge of agrarian structures. We show that a serious dating of agricultural remains must be based upon a criticall...

Looting and trade in cultural artefacts inside and outside Sweden.) Fornvännen 94. Stockholm. The illicit removal of artefacts, through lhe plundering of archaeological sites, monuments and museums, is today probably the most serious threat to the world's cultural heritage. The incentive to the plunder derives from the international antiquities märket where dealers and collectors ask no questions about provenance. The flow of cultural objects in this trade is from "source" to "märket" countries. The "sources" are, usually, impoverished countries with a rich cultural heritage. The "märkets" are countries in the Western world. International treaties designed to halt the illicit trade in cultural artefacts, such as the 1970 UNESCO and 1995 UNIDROIT Conventions, are ignored by the "märket" countries in Western Europé, nor are they supported by Western scholars. Sweden participates, albeit to a limited extent, in the international trade in artefacts and has shown little respect for the 1970 UNESCO and 1995 UNIDROIT Conventions. The artide condudes that Swedish scholars should take a stånd against the looting and the illicit/immoral trade in cultural artefacts.
