CHARACTERIZING THE DIET OF INDIVIDUALS AT THE NEOLITHIC CHAMBERED TOMB OF HAZLETON NORTH,GLOUCESTERSHIRE, ENGLAND,USING STABLE ISOTOPIC ANALYSIS*

Stable carbon and nitrogen isotope compositions were measured on human and faunal bones, sampled from the Neolithic chambered tomb of Hazleton North, Gloucestershire, UK. The values were used to characterize the diet of the burial community as a whole. Humans were higher in δ¹⁵N by 4.5–5.0‰ relative to animal δ¹⁵N, from which we conclude that, based on currently accepted interpretations of isotopic data, the humans consumed a diet that was very high in meat or animal products (75% by weight of protein). Comparison was also possible between cortical and cancellous femoral collagen, with the results showing no significant difference for the adult humans. The sample of human isotopic values showed little variability, in contrast to that found in the domestic and wild animals from the site (including cattle, pigs, sheep and deer). We suggest that this is due to local environmental differences, rather than to environmental change over time or physiological differences between individual animals, and that this pattern is likely to hold for many other archaeological sites when analysed with sufficient statistical weight.     

COINS,ARTEFACTS AND ISOTOPES—ARCHAEOMETALLURGY AND ARCHAEOMETRY*

Archaeometallurgy is one of the earliest manifestations of archaeometric research, using science‐based approaches to address cultural–historical questions. This review first outlines the extent of the field, defining in some detail the main branches of archaeometallurgy, and their specific methodological approaches. It then looks at some of the early publications pioneering archaeometallurgical research, to set the scene for the publication pattern of archaeometallurgy in general, and the role that Archaeometry played in publishing archaeometallurgical research. The analysis of archaeometallurgy‐themed publications in Archaeometry, their change over time and their relationship to the total range of work done in the field indicates that there is a rather narrowly defined and specific type of archaeometallurgy that gets published in Archaeometry, initially with a strong focus on coin and object analysis, often combined with method developments. The more recent developments in isotope‐based studies in archaeometallurgy find only a limited representation in the journal, despite the leading role that the Isotrace Laboratory played in this discipline, for some considerable length of time. More recently, this Archaeometry‐specific ‘flavour’ of archaeometallurgy seems to weaken, with an increase of papers on iron and on primary production in general, subjects still much under‐represented.     

TRACING THE RESOURCES OF IRON WORKING AT ANCIENT SAGALASSOS (SOUTH‐WEST TURKEY): A COMBINED LEAD AND STRONTIUM ISOTOPE STUDY ON IRON ARTEFACTS AND ORES*

Lead and strontium isotope analyses were performed by thermal ionization mass spectrometry (TIMS) on Roman to Byzantine iron artefacts and iron ores from the territory of ancient Sagalassos (south‐west Turkey), to evaluate Pb and Sr isotopes for provenance determination of ores for local iron production. It can be demonstrated that for early Roman artefacts and hematite iron ore processed in early Roman times from Sagalassos proper, as well as for magnetite placer sands and early Byzantine raw iron from the territory of the city, Sr isotopes are much less ambiguous than Pb isotopes in providing clearly coherent signatures for ore and related iron objects. Late Roman iron objects were produced from iron ores that as yet remain unidentified. Early Byzantine iron artefacts display more scatter in both their Pb and Sr isotope signatures, indicating that many different ore sources may have been used. Our study demonstrates that iron objects can be precisely analysed for their Sr isotopic composition, which, compared to Pb isotopes, appears to be a much more powerful tool for distinguishing between chronological groups and determining the provenance of raw materials.     

COMPLEMENTARY COMPOSITIONAL ANALYSIS OF FORMATIVE PERIOD CERAMICS FROM THE TEOTIHUACAN VALLEY

During the Classic Period, Teotihuacan was an economic centre of central Mexico, but little is known about the development of this system. This paper presents a pilot study in multi‐method analysis of Formative Period (1500/1400 bc –ad 150) ceramics from the Teotihuacan Valley. Pottery was characterized by instrumental neutron activation analysis, laser ablation inductively coupled plasma mass spectrometry, thermal ionization mass spectrometry and petrography. It appears that most pottery was made from local raw materials that differ from later Postclassic materials. Some inter‐village interaction is suggested by stylistic choices, and one settlement had a group of ceramics made from unequivocally distinct raw materials. The study demonstrates how complementary methods can be used to draw greater anthropological meaning from compositional differences.     

A SCULPTURAL MARBLE OF PRIME QUALITY IN ANTIQUITY—THE DOLOMITIC MARBLE OF THE SIVEC MOUNTAINS IN MACEDONIA

This paper presents analytical data on a major occurrence of fine‐grained dolomitic marble in the Sivec Mountains, close to the city of Prilep in today's former Yugoslavian Republic of Macedonia. This is the first presentation of an analytical database of a large‐scale source of fine‐grained dolomitic marble, whose ancient use can be demonstrated by tool marks and archaeological evidence. Many traces of ancient mining have fallen victim to a big modern quarrying operation in this area, which for decades has produced high‐quality blocks of marble (‘Macedonian Carrara’) and exported them all over the world. A combination of different analytical methods is used to characterize the marbles and to present a database for investigating ancient artefacts made of fine‐grained dolomites. Petrographic investigations revealed the very homogeneous micro‐fabric of this marble, which is of high purity with very low silicate contamination and has a maximum grain‐size of 1 mm. In addition to analysis of the stable isotopes, trace element analyses of carbonate lattice elements (Mg, Fe, Mn and Sr) were performed. An alternative method, the analysis of the chemical composition of the inclusion fluids, was also employed. On the basis of these techniques, a multivariate discrimination analysis was performed, and a clear separation of the different dolomitic marbles (Thasos, Ephesos, Proconnesos and Karacasu) was obtained. Finds of artefacts of high artistic quality made from this dolomite prove the existence of a significant workshop in the neighbourhood of the Sivec quarries. Because of its vulnerability to weathering, this fine‐grained dolomitic marble was used preferentially for indoor applications. Sculptures of prime artistic quality made of Sivec marble have so far been found in several locations of the Republic of Macedonia.     

Evidence for long-term averaging of strontium in bovine enamel using TIMS and LA-MC-ICP-MS strontium isotope intra-molar profiles

Abstract

High spatial resolution micro-sampling of tooth enamel offers the possibility of high temporal resolution isotope data to reconstruct climate, environment, diet and mobility. Questions remain about the duration and pattern of the maturation phase of enamel and the existence and direction of chronological 'time-lines'. LA-MC-ICP-MS measurements of c. 400 μm craters and TIMS analyses of transverse enamel sections of an archaeological bovine third molar were undertaken to investigate the long-term averaging of incorporated strontium. The same gradually increasing isotope profile was obtained from both approaches, indicating that the large increase in spatial resolution did not change the response profile obtained. The results suggest that even at the microscopic scale, strontium is incorporated over a period in excess of 12 months. Averaging of the input signal may result from both long-term retention of strontium in the skeleton and recirculation in the body pool, or long-term maturation of enamel on a microscopic scale. Whichever mechanism is responsible, it may not be possible to recover strontium isotope ratios with a high time resolution from cattle molar enamel unless there is a large imbalance in the amount of strontium supplied by different sources. Consequently, strontium isotope profiles may not be synchronous with those of lighter isotope systems.     

LEAD ISOTOPIC ANALYSIS FOR THE IDENTIFICATION OF LATE BRONZE AGE POTTERY FROM HALA SULTAN TEKKE (CYPRUS)

Lead isotopic compositions were measured for 65 sherds from five pottery wares (Plain White, Coarse, Canaanite, White Slip and Base‐ring) excavated from the Late Bronze Age site of Hala Sultan Tekke (Cyprus). The elemental composition and isotopic signature of the sherds were compared with those of 65 clay samples collected in south‐east Cyprus, mainly in the surroundings (<20 km) of Hala Sultan Tekke. This work shows the effectiveness of using lead isotopic analysis in provenance studies, along with other analytical techniques, such as X‐ray diffraction (XRD) and a scanning electron microscope (SEM) equipped with an energy dispersive X‐ray detection (EDX) facility, to identify the composition of pottery wares and the clay sources used for pottery ware production.     

MARBLE PROVENANCE INVESTIGATION OF ROMAN SARCOPHAGI FROM THESSALONIKI*

The provenance question of the marbles used for making the sarcophagi of local production of Thessaloniki in the Roman period had been posed by archaeologists in the past. The hypothesis was that the material came mainly from the quarries of Thassos Island. This paper presents the scientific analysis of 23 characteristic samples from selected sarcophagi at the Museum of Thessaloniki, using three different techniques: electron paramagnetic resonance (EPR) spectroscopy, stable isotope analysis and maximum grain size measurements, plus in-situ examination. New combinations of parameters were used in order to resolve fully the provenance of all samples. The results showed that the vast majority of the objects were indeed made in Thassian marble but from three different quarries, namely Vathy/Saliara (dolomitic marble), Aliki (calcitic marble) and Acropolis/Phanari (calcitic marble). The calcitic marbles from Aliki and to a lesser degree from Acropolis/Phanari are met in all the basic types of sarcophagi (framed type, plain type, garland sarcophagi). The use of the better quality and snow-white dolomitic marble from Vathy/Saliara quarries is relatively restricted and is often found in works that are above the average regarding the quality of their workmanship. In addition, two sarcophagi were made in Pentlelic marble and one in Proconnesian. The scientific analysis results provide a good confirmation of the archaeological estimates and, furthermore, the conclusions constitute henceforth a secure basis for the study of the entire sculptured works of Thessaloniki.     

SCIENTIFIC CHARACTERIZATION OF THE POHORJE MARBLES,SLOVENIA

As a former part of the great Roman Empire, Slovenia has many archaeological sites featuring buildings and objects entirely or partly constructed from marble whose provenance is doubtful. In Slovenia, the most probable source of such marble is the Pohorje Mountains. For the purpose of supporting further provenance studies, these marbles are fully scientifically characterized. The techniques used are petrographic and geochemical analysis, stable isotope ratio analysis and EPR spectroscopy. The results show that the Pohorje marbles are highly heterogeneous in both their isotopic and geochemical parameters as well as grain sizes. The parameters of the different Pohorje marble outcrops are compared between themselves and with the parameters of known ancient quarries in the Mediterranean and Austria. The use of a multi‐technique approach with combined parameters allows the best possible discrimination.     

MINERO‐PETROGRAPHIC AND GEOCHEMICAL CHARACTERIZATION OF ‘GRECO SCRITTO’ MARBLE FROM CAP DE GARDE,NEAR HIPPO REGIUS (ANNABA,ALGERIA)*

This work presents the results of the first mineralogical, petrographical and geochemical characterization of the marble quarried from the Cap de Garde headland, not far from Annaba (Algeria). This site is traditionally held by archaeologists to be the main source of supply of the so‐called ‘greco scritto’ marble, which was much used by the Romans for architectural and decorative–ornamental purposes, locally from the first century bc , and in Rome and central and southern Italy from the late Flavian period until the fourth century ad . The databank relating to the quarried material, created here for the first time, is used to establish the origin of ‘greco scritto’ found in six important Roman cities of North Africa: Hippo Regius and Cuicul (Djemila), in Algeria; Volubilis, in Morocco; Cyrene, in Libya; and Carthage and Utica in Tunisia. The results of this archaeometric study support the hypothesis (already put forward by authors) that the ‘greco scritto’used in the Roman Mediterranean originated from different sites, and suggest the existence of a number of North African quarries, also in the vicinity of Annaba.
