THE DISCOVERY OF ANOMALOUSLY HIGH SILVER ABUNDANCES IN POTTERY FROM EARLY ROMAN EXCAVATION CONTEXTS IN JERUSALEM*

This is the first study on the differential distribution and concentrations of silver in ceramics recovered from archaeological excavations. The chemical compositions of 1174 pottery vessels from 38 Roman‐period sites in Israel have been determined. Unusually high and variable abundances of silver were discovered in pottery samples of all vessel types and chemical compositions from four distinct archaeological contexts dating to late first century bce to 70 ce Jerusalem. The large majority of the Jerusalem vessels could be distinguished by their silver abundances from all analysed pottery pieces recovered at rural sites outside Jerusalem, even when the pottery types and chemical compositions, except for silver, of pottery found within and outside Jerusalem were indistinguishable. The evidence is suggestive of a human origin for the high and variable silver abundances, and dispersion of the silver by aqueous transport. The differential silver concentrations found in excavated pottery from Jerusalem and other urban and rural sites suggest that attention to the distribution of silver in pottery from excavated contexts may be helpful for evaluating the nature and function of archaeological remains and patterns of urban contamination.     

BLACK AND RED GRANITES IN THE EGYPTIAN ANTIQUITY MUSEUM OF TURIN: A MINERO‐PETROGRAPHIC AND PROVENANCE STUDY

A recent project to investigate the stone artefacts preserved in the Egyptian Antiquity Museum of Turin has been undertaken, with the aim of supplying their systematic classification and suggesting the provenance site of the original raw materials. This paper focuses on seven sculptures dating back to the New Kingdom (18th–19th Dynasties): the statue of Ramses II, three of the 21 sculptures of the goddess Sekhmet, the statue of the goddess Hathor, the Ram‐headed Sphinx and the sarcophagus lid of Nefertari. Petrographic observations have shown that all the sculptures are made of granitoid rocks, with variable composition from granite to granodiorite and tonalite. The observation of strong macroscopic analogies with the so‐called black and red granites outcropping in the Aswan area has suggested a common origin of all the raw materials used for their manufacture. In order to verify this provenance hypothesis, several samples were collected in the Aswan quarry districts. According to results of a minero‐petrographic and geochemical comparison between the statues and the Aswan quarry samples, it was possible to identify the source area of the stone sculptures and finally to highlight the importance of an archaeometric approach to the solution of archaeological problems.     

A GREEK METROLOGICAL KOINE: A LEAD WEIGHT FROM THE WESTERN BLACK SEA REGION IN THE ASHMOLEAN MUSEUM, OXFORD

Summary. A unique commercial lead weight from the western Black Sea region is examined in its metrological and historical context. The style and combination of relief symbols on the object (Athenian owl and Kyzikene tunny) suggest a quarter mina in a market weight system used equivalently at Athens and Kyzikos by the last quarter of the fifth century BC, and developed within a long-term process of broad commercial integration of the Aegean and Black Seas in Classical times. The authors consider such a process to have been caused by the economic motivations of individual city-states, not the direct Athenian imperialism expressed in the so-called Standards Decree.

The history and accomplishments of that laboratory are presented. Endeavours to preserve unpublished results are described. Results on Cypriote pottery are presented.     

ARCHAEOMETRIC INVESTIGATIONS OF SGRAFFITO CERAMIC TILES (FIFTEENTH‐SIXTEENTH CENTURIES) RECOVERED FROM EXCAVATIONS IN UDINE (NORTH‐EAST ITALY)*

Most of the Renaissance sgraffito tiles excavated in Udine (Italy) constitute a homogeous group, the tile body having a CaO/MgO molar ratio ?= 3:2. They were produced using a dolomite‐ and calcite‐containing clay fired at 900–950°C. A small group of samples, with a lower firing temperature and a CaO/MgO ratio ?= 2:3, was probably produced in a different factory. Slip and transparent glaze, characterized by optical microscopy and inductively coupled plasma atomic emission spectrometry, are an illite‐rich clay and a lead silicate, respectively.     

ANALYSIS OF THE FATTY DEBRIS FROM THE WRECK OF A BASQUE WHALING SHIP AT RED BAY,LABRADOR

Analysis of fatty material from barrels in a submerged wreck of a whaler in Labrador water showed it to contain free fatty acids, including some higher fatty acid, consistent with whale oil and certainly of marine origin. Conversion to adipocere was extensive but not complete.     

THE ANALYSIS OF DYESTUFFS FROM FIRST‐ TO SECOND‐CENTURY TEXTILE ARTEFACTS FOUND IN THE MARTRES‐DE‐VEYRE (FRANCE) EXCAVATIONS*

A series of Gallo‐Roman clothes and miscellaneous textile fragments from the first and second centuries from the Martres‐de‐Veyre necropolis (Puy‐de‐Dôme, France) was investigated. The objects studied were excavated between 1851 and 1923, during successive rounds of archaeological work. Since that time, they have been conserved in the Barguin Museum at Clermont‐Ferrand. The target of our research was dye identification, as it gives very interesting and useful information regarding the ancient technology. This approach has until now not been considered to be relevant and, unfortunately, is not systematic. The analysis was carried out by high‐performance liquid chromatography with photodiode array detection (HPLC–PDA). The small samples (threads up to 0.6 mg, less than 1 cm long) of coloured textile fibres were submitted to this technique. In one case, X‐ray fluorescence (XRF) analysis was applied. According to the analysis, the dyeing sources proposed are the Rubiaceae family for red, a luteolin ‘base’ for yellow, ellagitannins for brown and indigo for blue colours. Several samples did not seem to contain any dye. We point out possible factors for the partial dye source determination: instrumental limits, sample size, low dyestuff content in analysed samples and the dyes’ decomposition during ageing. Some improvements of dye analysis in archaeological samples by separation techniques based on recent analytical instrumentation and combined approaches are proposed.

FROM RESOURCE TO MARKET: POSTWAR SPATIAL CHANGES IN A SWEDISH FOREST COMPANY

Despite the wealth of empirical and theoretical literature on transnational corporations, little has been written about the spatial consequences of changes in the ownership of forest-based industries. These types of tnc embrace a broad range of activities, formerly based solely upon forest raw material, comprising sawmilling and pulp and paper manufacturing. In Sweden, these industries were mostly located near raw material supplies and concentrated on export production for the European market. During recent decades forest companies such as sca (Svenska Cellulosa Aktiebolaget) have invested in or acquired production and sales units in most of the traditional market countries. This has involved a substantial increase in the numbers of foreign employees, new commodities and raw materials, and a shift in the centre of gravity of production and employment. The aim of this article is to investigate and model the locational changes in sca 's ownership (of production, sales, and administrative units) and in its organizational structure within and outside Sweden, from the 1950s to the present.

URANIUM VARIATIONS IN A DATED FOSSIL BONE SERIES FROM OLDUVAI GORGE,TANZANIA

Of twelve elements analyzed in a series of bovid teeth from the Olduvai Gorge, uranium is the only element which varies appreciably with the ages of the samples. Uranium concentrations increase at first, then decrease with increasing age, and therefore cannot be used by themselves to obtain absolute or even relative ages of the samples. A model accounting for the behaviour of uranium is proposed in which uranium is absorbed in the samples during the decay of organic material and is lost after this decay ceases. If one accounts for uranium losses, the concentrations of uranium and its decay products may be used to accurately date skeletal material from the Olduvai gorge.     

THE PLACE OF CHRONOLOGICAL STUDIES IN ARCHAEOLOGY A VIEW FROM THE OLD WORLD*

This article deals with the univeral problem of chronological versus social change and discusses the methodological foundations and the scientific functions of chronological studies, exemplified by the Nordic Bronze Age, a classic example of the development of a chronological system. First the universal validity of the premises of typology and seriation are questioned. Secondly, there is a discussion of the chronological implications of the many possible relationships between the period of production, the period of use and the period of deposition of artefacts. Thirdly the foundations of chronological change is analysed and finally the place of chronological studies in the research process is discussed.     

THERMOLUMINESCENCE DATING OF A CRUCIBLE FRAGMENT FROM AN EARLY TIN PROCESSING SITE IN TURKEY

Archaeological exploration in the Taurus mountains at Göltepe in south-central Turkey has uncovered a site indicating the presence of extensive tin ore mining and smelling operations The most recent find of smelting crucible fragments allowed for a thermoluminescence-hased age determination spanning a late fifth to early third millennium BC date. This result is consistent with a number of radiocarbon dates derived for charcoal also found at the site. The importance of this site relates to the possible tin production and subsequent trade with southwestern Asia which would have provided this otherwise scarce ingredient to bronze technology in that area. This date is directly for crucible material and thus confirms the antiquity of tin smelting at Göltepe.
