Energy dispersive X-ray fluorescence analysis of 1st millennium ad glass from Britain

A series of energy dispersive X-ray fluorescence analyses has been undertaken in response to archaeological problems relating to 1st millennium AD glass excavated in Britain. The aim of the work was to furnish a set of comparable analytical results to be used in assessing hypotheses concerning the general state and development of glass technology through this period. Within this framework, however, it has also been possible to attempt answers to specific archaeological questions relating to material from particular sites. The paper discusses the background to, and the interpretation of such results, particulars of the analytical technique used, a general overview of approximately 200 analyses and three examples of the use of this data in relation to specific archaeological problems.     

Spinoza's counter-aesthetics

ABSTRACT

Spinoza says very little about art or literature in his work; a fact which partly explains the absence of references to him by the German initiators of aesthetics in the eighteenth century, including Baumgarten, Kant and Hegel. Spinoza's resolute opposition to teleology, however, provides an even more compelling reason for his absence, given the teleological conception of literary and artistic form common to the notion of aesthetics at the time of its emergence. Is it possible to fashion a counter-aesthetics from the materials provided by Spinoza's philosophy? I argue that his reading of the great Spanish Baroque writers, especially Luis de Góngora and Baltasar Gracián (whose works were found in his library), provided him with an alternative conception of literary form based on a rejection of formal coherence and closure in favor of constitutive incompleteness and an opening to the infinite.     

The distribution and provenance of archaeological obsidian in central and eastern Europe

The sources of archaeological obsidian in central and eastern Europe are briefly described and analyses of 48 samples from 10 of these sources in northeast Hungary and southeast Slovakia are reported. Instrumental Neutron Activation Analysis was used to determine 16 trace elements and two major elements. Principal Components Analysis supported by Discriminant Analysis showed seven analytical groups in these data. A total of 270 pieces of archaeological obsidian were assigned by Discriminant Analysis to three of the Carpathian source groups defined, the remaining four source groups not being represented in the archaeological record. The three source groups used are: (1) Szöllöske and Málá Toron?a in Slovakia (designated group Carpathian 1); (2) Csepegö Forrás, Tolcsva area, Olaszliszka and Erdöbénye in Hungary (Carpathian 2a); and (3) Erdöbénye (Carpathian 2b). Carpathian 2a and 2b type obsidians are both found at the re-deposited source of Erdöbénye. Carpathian obsidian was used most widely in Hungary, Slovakia and Romania, and also reached south to the Danube in Yugoslavia, west to Moravia, Austria and to the Adriatic near Trieste, and north to Poland. Carpathian 2a obsidian was used in the Aurignacian period, Carpathian 1 in the Gravettian and Mesolithic, and Carpathian 1, 2a and 2b in the Neolithic, when Carpathian 1 predominated and obsidian use was at its most intensive. Only Carpathian I type has been identified in the Copper and Bronze Ages. There is no evidence at present for any overlap between the Carpathian obsidian distribution and the distributions of the Near Eastern or Aegean sources, but there is an overlap with Mediterranean obsidian at the Neolithic site of Grotta Tartaruga in northeast Italy where Liparian and Carpathian 1 material were identified. The distribution of obsidian from the Carpathian sources is considered in terms of linear supply routes. Based on limited available evidence the supply zone is significantly smaller and the rate of fall-off with distance slightly lower than that reported for Near Eastern obsidians.     

The distribution and sources of archaeological obsidian from southern France

One-hundred-and-sixty-two pieces of obsidian have been found at 50 archaeological localities in southern France. The distribution is concentrated in the Rhône Valley, but includes sites in Drôme and in southwest France. The obsidian is mainly from sites of the Chassey culture (4th and 3rd millennium Neolithic), but there is one Impressed Ware site (Early Neolithic) and four Copper Age sites with obsidian. Only a small proportion of the obsidian (31 pieces) consists of waste pieces, providing little evidence for on-site working. 10 pieces of obsidian were analysed by instrumental neutron activation analysis to determine their geological provenance. Seven pieces proved to be from the Sardinian SA source, one from Lipari, and two from Pantelleria. Chronologically there is some division between sources used: all three pieces of Liparian obsidian so far identified from southern France, in this work and by earlier researchers, belong to Early Chassey contexts, and the two Pantellerian pieces are from a Copper Age dolmen. Sardinian and Liparian obsidian probably reached France by way of northern Italy. where both types were in use in contemporary cultures. The two Pantellerian pieces are evidence of some type of contact between France and the southern Mediterranean in the Copper Age, despite earlier suggestions of a very restricted distribution for the Pantellerian source. Obsidian was probably imported to southern France with other goods since the small amounts used would not warrant a separate trading network for obsidian alone.
