Elemental characterisation of Barbar ceramics from Tell Abraq

The early second millennium levels at Tell Abraq have yielded over 600 fragments of friable, red-ridged pottery with exploding lime grits which is superficially indistinguishable from contemporary, so-called 'Barbar'pottery on Bahrain (1). The Bahraini origin of the Tell Abraq Barbar sherds has been demonstrated by means of proton-induced x-ray and gamma-ray emission (PIXE/PIGME) analysis. In addition, the results of x-ray fluorescence (XRF) of Barbar pottery from Saar on Bahrain (2) have been re-examined, showing that the subgroups which characterise the Tell Abraq material correspond to those found in the Saar corpus. The techniques used on the Tell Abraq and Saar material – PIXE/PIGME and XRF – are compared.     

A Provenance Study of Early Bronze Age Artefacts Found in Asturias (Spain) by Means of Metal Impurities and Lead,Copper and Antimony Isotopic Compositions

We describe here the first combined isotopic and impurities study on 27 copper artefacts found in the north‐west of Spain. This study follows previous studies on the lead isotopic composition of copper ores in three local mines that were exploited during the Bronze Age. The levels of impurities found were clearly different from ingots and axes, with ingots having much higher levels of impurities. It was not possible to differentiate the origin of the artefacts only by the impurities present. On the other hand, the lead isotopic composition indicated that all artefacts were prepared from local ores, the ‘La Profunda’ mine being the most probable source for most artefacts that carried out a clear radiogenic lead signature. The copper isotopic composition seemed to be able to differentiate artefacts from the ‘El Aramo’ mine from those from the ‘El Milagro’ and ‘La Profunda’ mines. On the other hand, the antimony isotopic signature was not useful for source allocation.     

Atacamite pigment at Tell Abraq in the early Iron Age

X-ray powder diffraction analysis identified a concentration of green pigment in a shell from Tell Abraq as the copper mineral atacamite. The use of atacamite as a pigment in the ancient world is discussed.     

The Chronology of the Southeast Arabian Iron Age

Drawing on the results of the Australian Archaeological Expedition's excavation of Tell Abraq, a three-fold division of the southeast Arabian Iron Age is suggested. A re-analysis of ¹⁴C data in line with the latest agreed calibration curve together with an analysis of the foreign parallels of southeast Arabian Iron Age pottery permits the construction of a complete Iron Age sequence. The results argue for a lower chronology for the Iron II and III periods than has, up until now, been suggested.     

Asimah: Neue 14C-Datierungen zum späten 3. vorchristlichen Jahrtausend auf der Halbinsel Oman

The third millennium BC domestic sites of Asimah (Emirate of Ras al-Khaimah, U. A. E.), excavated in 1988 and published in 1994, produced a common Umm an-Nar inventory, but with a high percentage of imported Indus Valley pottery. A comparison of finds with the well-stratified Hili-8 sequence is contrasted with five new radiocarbon dates which, together with the artefacts recovered, place Asimah in the late third millennium BC chronological and cultural context of Tell Abraq.     

An examination of metal objects from Tell Abraq, U.A.E.

Four metal objects excavated at Tell Abraq in 1989 and dating to the Bronze Age and Iron Age were analyzed at the Technical University of Copenhagen. The results are reported here and the implications of the work are discussed.     

Multi-disciplinary research on the past human ecology of the east Arabian coast: excavations at Hamriya and Tell Abraq (Emirate of Sharjah, United Arab Emirates)

The results of two seasons of research at Hamriya and Tell Abraq (Sharjah, UAE) by an international team of researchers are presented. The research has revealed extensive evidence for occupation from c. 5000 BC to the recent past adjoining lagoon areas that face the Arabian Gulf. C¹⁴ analysis of shells has contributed to understanding the chronology of settlement and also assisted our understanding of species-specific deviation from the global reservoir effect.     

ON THE COMPOSITION AND PROVENANCE OF METAL ARTEFACTS FROM POLIOCHNI ON LEMNOS

Summary. The majority of the well-stratified Early Bronze Age metal objects from Poliochni, with the exclusion of one hoard find, was analyzed for their chemical and lead isotope composition. The results show that a major change occurred in the metal used at Poliochni during periods contemporary with Troy I and Troy II. Unalloyed or arsenical copper with relatively high lead contents during the earliest two periods 'azzurro' and 'verde' is gradually replaced and supplemented by tin bronze which, during period 'giallo', i.e., by the end of Troy II, becomes the dominant metal type. Lead isotope abundance ratios in the earlier artefacts are consistent with a derivation of the metal from regional ore sources but the trace element abundance pattern is not. Concurrent with the appearance of tin bronzes is an increase in the diversity of ore deposits exploited; for about one third of the artefacts from period 'giallo' there is as yet no matching ore source in all Anatolia and the Eastern Mediterranean. It is argued that the tin bronzes have been imported as such but that the lead isotope signature does not provide any direct clues to the origin of the tin.     

Empires and resources: Central Anatolian obsidian at Urkesh (Tell Mozan,Syria) during the Akkadian period

Almost all of the obsidian used to craft stone tools in the Near East from the Palaeolithic onward originated from volcanoes in two geographic regions: Central Anatolia and Eastern Anatolia. Five decades of obsidian sourcing has led to the view that Central Anatolian obsidians largely followed the Mediterranean coast and rarely reached farther east than the Middle Euphrates, whereas Eastern Anatolian sources almost exclusively supplied sites east of the Euphrates. This paper discusses the identification of Central Anatolian obsidian artefacts at the Bronze-Age site of Tell Mozan (Urkesh) in northeastern Syria. Most of the obsidians at Tell Mozan (97%) came from the Eastern Anatolian sources, as expected from established distribution models. Artefacts of Central Anatolian obsidian, however, were excavated from one well-constrained context: the deposits on a palace courtyard that date to the height of the Akkadian empire's influence at this third-millennium Hurrian religious and political centre. In particular, the obsidian came from the Kömürcü source of Göllü Da?. Potential explanations for this exotic obsidian are discussed. This obsidian might have “piggybacked” on the distribution of Central Anatolian metals or arrived at this city as royal gifts or prestige items. Other discussed mechanisms include Akkadian-linked changes in either territoriality involving pastoral nomads responsible for the arrival of Eastern Anatolian obsidians or identity construction of elites based on involvement in Central Anatolian economic and political networks.     

Residential mobility and social identity in the periphery: strontium isotope analysis of archaeological tooth enamel from southeastern Arabia

Strontium isotope analysis represents an effective means of assessing mobility and reconstructing geographic residence patterns in archaeological populations. This biogeochemical technique was utilized to test the hypothesis that burgeoning interregional exchange networks and the occurrence of exotic grave goods in local tombs would correspond with a highly mobile population and a considerable immigrant presence during the Umm an-Nar (2700–2000 BC) period in the UAE. This region has been considered peripheral relative to larger civilizations in Mesopotamia and the Indus Valley, but played an important role as a major supplier of copper for the Persian Gulf. Individuals (n = 100) from six monumental Umm an-Nar tombs (Mowaihat; Tell Abraq; Umm an-Nar Island I, II, V; Unar 1) were selected to evaluate the geographic origins of tomb members. Mean ⁸⁷Sr/⁸⁶Sr ratios from local individuals interred at Mowaihat (0.708863 ± 0.000014; 1σ, n = 12), Tell Abraq (0.708873 ± 0.000020; 1σ, n = 27), Umm an-Nar Island (0.708902 ± 0.000079; 1σ, n = 33), and Unar 1 (0.708805 ± 0.000065; 1σ, n = 25) all display little isotopic variability, indicative of a population that was not highly mobile. However, coupled with archaeological evidence, three immigrants from Tell Abraq (n = 2) and Mowaihat (n = 1) identified by deviant strontium values suggest that this region was actively engaged in interregional interaction. Despite claims that these tombs acted as visible markers of territoriality legitimized by local ancestors buried within them, the presence of non-locals suggests that as commerce became increasingly important, definitions of kinship and social identity may have become more flexible to better meet the needs of the local community and those with whom they interacted.     

Preliminary report on the archaeobotanical investigations at Tell Abraq with special attention to chaff impressions in mud brick

Examination of impressions from chaff-tempered mud brick proved rewarding, given the poor preservation of carbonised seed and grain material at Tell Abraq. Individual chaff elements were found to be recognisable from the impressions and it was shown that naked wheat and barley chaff were used as a tempering medium. Charcoal samples indicate that two species of mangrove were present, one of which is no longer found in the area. Tamarisk and Ziziphus were also present. Date charcoal was common. This study remains preliminary, and further sampling and analyses have been planned for the future.     

Attempting to Identify Activities in the Past: Preliminary Investigations of the Third Millennium BC Population at Tell Abraq

This paper reviews attempts by osteologists to identify activities in the past through examination of particular alterations to skeletal remains. Following an outline of the history of interest in occupational pathology, the physiology of bone is briefly summarised in order better to understand the potential of investigating occupation in the past. A history of archaeological research and interpretations in this field is then provided, followed by a discussion of a particular case study in which the human skeletal remains and material culture from the site of Tell Abraq were examined by the author in an attempt to identify bone alterations which may be attributed to certain activities.     

Building Pâris’ Beden Seyad: a replica of the Omani 19th‐century sewn fishing vessel

The beden seyad is a simple yet elegant Omani sewn fishing craft documented by the French naval officer François‐Edmond Pâris during his visit in Oman in 1838–1839. A 10m‐long scaled‐down replica of the vessel was built by a team of experts in a traditional boatyard in Qantab, the Sultanate of Oman, and is displayed in the Maritime History Gallery at the National Museum of Oman. This article describes different aspects of the building process of the vessel, from the material used to the method of construction. It compares the different versions of the beden drawing provided by Pâris and discusses the decision‐making and problem‐solving procedures carried out by the construction team.     

The medieval iron market in Ariège (France). Multidisciplinary analytical approach and multivariate analyses

The medieval iron market in Ariège (French Pyrenees) is characterised by its complexity leading to many questions regarding the ore used in relation to the artefacts encountered in archaeological settings. Despite the conclusive study of the treaty that regulated iron vs. coal exchanges from the 14th to the 19th c. by Verna et al., many questions remain unanswered concerning provenance and circulation of ores and products. Based on a combination of trace elemental analysis and multivariate statistical methods (discriminant analysis, hierarchical clustering analysis), we propose to follow an elemental-based signature from ore to artefacts, suited to the direct iron process, to clarify provenance hypotheses. We define the chemical signature of the Ariège area and compare it to that of slag inclusions in artefacts uncovered in several main archaeological sites from the Ariège area but also outside of this region. The results from this study are consistent with prior knowledge from historical sources. In the Ariège region, results highlight the multiple origins of products encountered at Montréal-de-Sos, a site close to known trade routes, whereas the isolated Castel-Minier site primarily contained objects from local ores and most objects retrieved from the Mirabat castle (Couserans) are coming from outside Ariège, possibly an indirect consequence from the exchange treaty. The presence of pins made of Ariegean ores is also demonstrated in the far more distant Capestang collegiate (near Narbonne, outside Ariège). This opens the way to finer studies in the politico-economical control of the iron supply for the building of medieval monuments in Southern France.     

About two seal-impressed jars from Tell Abraq (Emirate of Umm al-Quwain). New evidence for intercultural networks in the lower Arabian Gulf in the late 2nd – beginning of the 1st millennium BC

Ongoing excavations at Tell Abraq (Emirate of Umm al-Quwain, U.A.E.) are revealing new aspects of this multiperiod site, which was occupied from c. 2500 BC to 300 AD. Together with substantial architecture dated to the 2nd and 1st millennia BC, relevant assemblages of archaeological materials are being collected and dated to different phases of the site’s life. Among this material, exceptional is the discovery of two jars bearing the impression of two different cylinder seals, which will be presented here. Seal impressions on any media are extremely rare in the whole of south-eastern Arabia and strongly indicate a foreign provenance for the jars. Their iconographic study, the fabric and morphological parallels for the jars, and probable chronology will be discussed, as this can highlight transmarine connections during the late 2nd-first half of the 1st millennium BC, as well as provide new data to address chronological issues in south-eastern Iran itself.     

Tell Abraq during the second and first millennia BC: site layout,spatial organisation,and economy

Research recommenced at Tell Abraq in 2007, carried out by Bryn Mawr College with an international team in co‐operation with the Sharjah Archaeology Authority. Between 2007 and 2010 fieldwork was limited to documenting sections of the previous excavations and one small sounding while our attention focused mainly on the nearby shell‐midden site of Hamriya and the fortified Iron Age settlement site of Muweilah. Since 2010, large‐scale excavations have been conducted which have fundamentally altered our understanding of the layout of the settlement and its economic relations during the second and first millennia BC. In this report, we detail the results of this work and present preliminary interpretations.     

Moving metals or indigenous mining? Provenancing Scandinavian Bronze Age artefacts by lead isotopes and trace elements

The aim of this study is to further the discussion as to whether copper was extracted locally or imported to Sweden during the Bronze Age or if both of these practices could have coexisted. For this purpose, we have carried out lead isotope and chemical analyses of 33 bronze items, dated between 1600BC and 700BC. Among these are the famous Fröslunda shields and the large scrap hoard from Bräckan and other items from three regions in southern Sweden which are also renowned for their richness in copper ores. It is obvious from a comparison that the element and lead isotope compositions of the studied bronze items diverge greatly from those of spatially associated copper ores. Nor is there any good resemblance with other ores from Scandinavia, and it is concluded that the copper in these items must have been imported from elsewhere. The results furthermore indicate that there are variations in metal supply that are related to chronology, in agreement with other artefacts from Scandinavia as well as from other parts of Europe. Altogether these circumstances open up for a discussion regarding Scandinavia’s role in the maritime networks during the Bronze Age.     

Copper quality and provenance in Middle Bronze Age I Byblos and Tell Arqa (Lebanon)

Forty-four Middle Bronze Age I weapons discovered at the sites of Byblos and Tell Arqa in Lebanon were investigated in order to study their copper quality and provenance. The evaluation of copper qualities is based on quantifying permanent inclusions such as copper sulfide and lead globules. The provenance of copper was studied using lead isotope analyses. For further discrimination between copper groups and sources elemental analyses by PIXE were performed on some of the weapons investigated. The results revealed two copper groups that could be qualified as “dirty” copper and “clean” copper. The former was used in most of the weapon types whereas the latter was reserved for items made of high-tin bronzes (>11 wt%) which underwent heavy hammering during the manufacturing process. Even though several potential copper sources were identified, the data point to Iran and Oman as the most probable areas of origin for the metal used in these weapons. These results contribute to the study of inter-regional exchange networks in the ancient Near East.     

Environment and collapse: Eastern Anatolian obsidians at Urkesh (Tell Mozan,Syria) and the third-millennium Mesopotamian urban crisis

The Early to Middle Bronze Age transition in Northern Mesopotamia has received great attention for the apparent concurrence of aridification, deurbanisation, and the end of the Akkadian empire around 2200 BCE. Our understanding of the “crisis” has been almost exclusively shaped by ceramics, demography, and subsistence. Exchange and the associated social networks have been largely neglected. Here we report our sourcing results for 97 obsidian artefacts from Urkesh, a large urban settlement inhabited throughout the crisis. Before the crisis, six obsidian sources located in Eastern Anatolia are represented among the artefacts. Such a diversity of Eastern Anatolian obsidians at one site is hitherto unknown in Mesopotamia. It implies Urkesh was a cosmopolitan city with diverse visitors or visitors with diverse itineraries. During this crisis, however, obsidians came from only two of the closest sources. Two to three centuries passed before varied obsidians reappeared. Even when an obsidian source reappears, the raw material seems to have come from a different collection spot. We discuss the likely exchange mechanisms and related social networks responsible for the arrival of obsidians at Urkesh and how they might have changed in response to climatic perturbations and regional government collapse.
