Geochemical and Magnetic Provenancing of Roman Granite Columns from Andalucía and Extremadura, Spain

One hundred and fifty two granite columns were examined in eight towns and archaeological sites in Andalucía and Extremadura, Spain, in order to determine the geological provenance of the columns. Three non-destructive methods of characterization were used: mineralogical features, magnetic susceptibility, and concentrations of radioelements (K, U, Th) determined by portable gamma ray spectrometry. Columns were compared with potential sources within Spain and in the Mediterranean area using analogous data previously published and also new data obtained for this work. The majority of the columns are made of Spanish granites, some of which were probably quarried near Mérida. Different chemical types of Spanish granites were used in the northern part of the area studied (Extremadura) and in the southern part (Andalucía). Twenty five columns are not of Spanish granites, but were imported from other sources, namely the Troad and Kozak Dağ areas of western Turkey, the Italian islands of Elba and/or Giglio, and Sardinia (confirming a column previously identified in the literature). The imported columns are found in Itálica, Hispalis (Seville) and Astigi (Écija), and were probably carried along the River Guadalquivir and its tributaries.     

The Hungarian and Slovak sources of archaeological obsidian: an interim report on further fieldwork,with a note on tektites

This report describes the results of fieldwork carried out in the Zemplén Mountain area of north-eastern Hungary in 1975. The aim of this work was to locate and sample geological sources of obsidian which may have been used by prehistoric man. These sources are of increased importance since the work of Nandris (1975) showed that the Romanian “sources” do not produce workable obsidian. During the fieldwork three sources in Hungary were visited and sampled; one of these was the previously unlocated source of Csepegö Forräs. A number of other possible localities for geological obsidian are mentioned in 19th and 20th century geological and archaeological literature, and the present state of knowledge with regard to these is summarized. Further sources exist in central and in south-eastern Slovakia. These sources were not visited but material has been obtained from both areas. The central Slovak sources do not produce workable obsidian and are not therefore relevant to archaeological studies. Obsidian from three localities in south-eastern Slovakia is of good glassy quality and further fieldwork is now needed to check the validity of these localities as geological sources. Reference is made to obsidian sources in the western U.S.S.R., and the problem of the use of tektites in archaeological sites is discussed.The obsidian samples obtained during this work are currently being analyzed using neutron activation, in order to characterize the sources on the basis of their trace element analysis and thus to relate them to archaeological obsidian from central and eastern Europe.     

Staging the Interior: The Public and Private Intimacies of Thomas and Jane Welsh Carlyle's Domestic Lives

‘Home’ is one of the most evocative and comforting words in the English language. It produces, at least in its idealized form, notions of safety, comfort, privacy, individuality and communion with family and friends. The supposed autonomy or permanence of home, however, is undermined frequently throughout one's life course revealing instead spaces of interactionism, public disturbance, discomfort, conflict, labour, stress and even violence. Reading Thomas and Jane Welsh Carlyle's voluminous letters one reads the emotional and psychological importance of ‘home’ and the vital necessity of the ideal world apart. The middle-class home was meant to stage a domesticated and comfortable private haven, withdrawn from public view and distant from the imperatives of the economy and politics, however, the house was also the physical representation, the outward ‘sign’, of the Carlyles' public identity. How the House looked and functioned – externally and internally – represented the Carlyles to the outside world. Home was, as Walter Benjamin alluded, like a sheltered theater box from which the occupants looked at the stage of the outside world and also the stage upon which the outside world cast its own critical eye on the action within. The necessities of life and the public fascination with the interior signify that private and public are largely mutable concepts. Any clear distinction between inside and outside, private and public are complicated as we look at the intimacies of the Carlyles' lives.     

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 pitchstone in Britain

Pitchstone is a glassy volcanic rock, distinguishable from obsidian by having a higher water content. It forms lava flows and minor intrusions at several centres within the British Tertiary Volcanic Province (BTVP) in the west of Scotland and Ireland. Pitchstone artifacts and waste pieces have been recorded from 101 archaeological localities in Scotland and northern England, ranging in time from possibly Mesolithic to Bronze Age. To characterize the sources, 17 pitchstone samples from 11 sources within the BTVP were analysed for major elements by energy-dispersive X-ray fluorescence (EDXRF), and for trace elements by instrumental neutron activation analysis (INAA). 28 pitchstone pieces from 22 archaeological sites were analysed, mainly non-destructively, by INAA and interpreted as having originated from Arran sources. The Arran sources are divided into four petrographic types; the Corrygills, Tormore, Glen Shurig and Glen Cloy Types. Petrographic study of 15 archaeological samples indicated that three were of Corrygills type and two were of Tormore type. The remainder were less confidently attributed to the petrographic types distinguished. Arran pitchstone is found as far as 300 km from the Arran sources, at the chambered tomb of Ord North in Highland.     

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.
