Ceremonial objects or household items? Non‐destructive μ‐XRD2 and μ‐XRF studies on three Neolithic hematite axes from Qatar

Three small stone axes were collected by the joint Qatari‐German South Qatar Survey Project (SQSP) at two places close to the eastern and western coast of Qatar in autumn 2012. Associated with settlement remains, flint artefacts and pieces of ?Ubaid pottery, the implements have been dated to the fifth millennium BCE. Non‐destructive μ‐XRD² and μ‐XRF analyses could, for the first time, prove the use of hematite as the raw material for the manufacture of these tools in Arabia. The absence of major hematite sources in the region and the special characteristics of hematite — a unique metallic shine of polished pieces and the blood‐red colour that appears during the manufacturing process — suggest the highly symbolic character of these objects.     

Between rocks and a hard place: prehistoric funerary practices at Wādī Ḍebayʿān,northern Qatar

Archaeological survey by the Qatar National Historic Environment Record Project (QNHER) in 2009, led to the discovery of a Neolithic flint scatter, a settlement and an ancient, raised shoreline associated with higher, mid‐Holocene sea levels at Wādī ?ebay?ān, north‐western Qatar (Al‐Naimi et al. 2010, 2011; Cuttler, Tetlow & Al‐Naimi 2011). The QNHER project is a collaboration between Qatar Museums and the University of Birmingham, which over the past five years has developed a national geospatial database for the recording of archaeological sites and historic monuments in Qatar. A significant aspect of the project involved archaeological survey and excavation in advance of major construction projects. Between 2012 and 2014 excavations at Wādī ?ebay?ān revealed a burial of a typology previously unknown in Qatar, the unmarked graves (Cuttler, Al‐Naimi & Tetlow 2013).     

A comparative geochemical study of bituminous boat remains from H3, As-Sabiyah (Kuwait), and RJ-2, Ra's al-Jinz (Oman)

This paper presents a geochemical analysis of fragments of bituminous amalgam from H3, As‐Sabiyah (Kuwait), and RJ‐2, Ra's al‐Jinz (Oman). The fragments bear barnacles on one side and reed impressions on the other, and are thought to have been part of the coating of reed‐bundle boats. The material from H3 dates to between 5300–4900 BC, while that of RJ‐2 dates to 2500–2100 BC. Samples from both sites were geochemically compared to archaeological and ethnographic material from Kosak Shamali (northern Syria, c.5000–4400 BC), RH‐5 (Oman, 4400–3500 BC) and Baghdad (central Iraq, 1900 AD). The composition of the bituminous amalgams was studied in detail. Rock‐Eval Pyrolysis gave a measure of Total Organic Carbon in the samples, and allowed an initial comparison of the data sets using various parameters. Examination of the proportions of soluble and insoluble organic matter allowed an assessment of the quantity of vegetal matter added to the bitumen to make the bituminous amalgam. The composition of the Ra's al‐Jinz material was studied using X‐Ray Diffraction analysis and thin‐section petrography, in order to assess the proportions of various minerals in the bituminous amalgams. It was concluded that the recipe for the bituminous mixture used to coat reed‐bundle and wooden boats did not differ significantly from that commonly used to make ‘mortar’ for architectural purposes in Mesopotamia. Traces of animal fats or fish oils were not found in the analysed Ra's al‐Jinz material, in contrast to previous hypotheses regarding the composition of the mixture. Comparison of the gross composition of extractable organic matter (the constituents of pure bitumen, soluble in chloroform or dichloromethane) showed the progressive effects of weathering on the samples. The isotopic composition of the bituminous material from H3 and the other sites was then compared to that of bitumen seeps and crude oils from Mesopotamia, Iran and Oman. The most significant result is that the material from As‐Sabiyah originated in Kuwait, at a surface seep at Burgan, while the material from Ra's al‐Jinz had a source in northern Mesopotamia.     

A characterisation study of Ubaid period ceramics from As-Sabbiya,Kuwait, using a non-destructive portable X-Ray fluorescence (pXRF) spectrometer and petrographic analyses

The Ubaid cultural phenomena (6500–4200 BC) of southern Mesopotamia has been used to characterise other archaeological sites in the Arabian Gulf region. The aim of this inquiry is to explore the nature of the interaction between the homeland of the Ubaid and the wider Gulf region. Through the use of a non-destructive portable X-ray fluorescence (pXRF) spectrometer, this study seeks to characterise and identify the chemical and mineralogical compositions of the ceramic assemblage from the Bahra 1 site of the As-Sabbiya region, Kuwait. The chemical results demonstrated that a combination of six trace elements [rubidium (Rb), strontium (Sr), yttrium (Y), zirconium (Zr), niobium (Nb) and barium (Ba)] occur significantly enough to delineate clay-based artifact groups—local red coarse from Ubaid, while the mineralogical analysis confirms the pXRF result and identifies the source of the raw materials and temper as well. Also, the comparison between the Ubaid and Bronze Age assemblage results suggests that potters used different clay resources within their own regions and/or production techniques.     

The Mesopotamian frontier of the Arabian Neolithic: A cultural borderland of the sixth–fifth millennia BC

The material culture of coastal Arabian Neolithic sites of the sixth–fifth millennia BC contains a range of small Mesopotamian-style objects, in addition to Ubaid pottery. There is a significant concentration of such objects at the Kuwaiti sites, H3 and Bahra 1, with lesser amounts in the Central Gulf region and virtually none in the Lower Gulf. The combination of material and symbolic culture at the Kuwaiti sites indicates that their inhabitants could communicate with both Ubaid and Neolithic peoples with equal facility, implying a key role in the region’s earliest experiments in maritime trade. Moreover, the presence in southern Iraq and at Susa of distinctive arrowheads, and possibly Arabian Coarse Ware ceramics, suggests that the range of eastern Arabian Neolithic peoples extended all along the ancient shoreline to the vicinity of the Mesopotamian Ubaid settlements, and even Susiana. The bifacial pressure-flaked arrowheads are of two different types that are well attested in eastern Arabia, though one type is more common in southern Iraq and Susiana, hinting at a local population related to the Arabian Neolithic. These finds are quantified and illustrated in this paper, and indicate a cultural borderland stretching for around 300 km north of Kuwait.     

Chalcolithic settlement of Bahra 1 and its possible functions

Excavations of the Kuwaiti–Polish Archaeological Mission at the site of Bahra 1 in Kuwait uncovered the remains of a large settlement from the sixth millennium BC, associated with the Mesopotamian Ubaid culture. This connection is made clear by the presence of Ubaid Ware from the Ubaid 2/3 phase that appears alongside Red Coarse Ware typical for the Arabian Neolithic. Architecture of the settlement resembled the Ubaid one with orthogonal, multi-chambered houses. In one part of the site they form a dense block with traits that indicate some degree of spatial planning. This type of spatial arrangement is absent in Arabian Neolithic settlements and is also unknown from Ubaid settlements in Mesopotamia. One of the buildings discovered at Bahra 1 has a ground plan reminiscent of a sanctuary from Eridu XVI and was probably associated with cultic activities, as was a circular stone enclosure (Unit 6), representing local building traditions. The character of Bahra 1 architecture and the presence of cultic buildings at the site suggest that the settlements served as a local ceremonial and/or cultic centre.     

The earliest settlement remains at the Ubaid-related site of Bahra 1 (Kuwait)

The settlement at Bahra 1 lies in the As-Sabbiya dessert, Kuwait. The site was preliminarily dated to the Ubaid 2/3 period, with four settlement phases distinguished so far. Phases A–C yielded remains of sturdy stone architecture, while the oldest Phase D was represented by a fire-pit horizon, as well as thin and low walls, perhaps serving as foundations for light and perishable superstructures. Even in the earliest phase, Mesopotamian influence is visible, evidenced by the structures’ orthogonal plan and the high percentage of Ubaid ware. Although the remains of the earliest phase were preserved very fragmentarily and over a limited area, they shed more light on the character of the earliest settlement activity in the region.     

Ceramic form and function in the Neolithic Gulf. A view from Bahra 1

This paper discusses the possible functions of ceramic vessels in the Neolithic Gulf, based on new data from the Ubaid-related settlement of Bahra 1 (Kuwait). Two pottery groups identified at the site—Ubaid Ware and Coarse Red Ware—are found in great numbers and variety of forms which provides grounds for a reconsideration of the role of pottery vessels in the societies of the Gulf. Analysis of this material reveals a more varied function of pottery vessels compared to that suggested in earlier studies. It was also possible to define the function of certain pottery vessels in more detail, both in their economic and social context.
