The aim of the paper is to summarise the present state of knowledge concerning bitumen trade in the Near East from the Palaeolithic (70,000 BP) to the Early Islamic period. During the Palaeolithic and Early Neolithic period, bitumen utilisation was mostly concentrated in settlements close to oil seeps. From the Ubaid 3 period, bitumen from the Mosul area became more important and was traded as far as the southern Persian Gulf. The Uruk period is a turning point for Mesopotamian history as settlements evolved into city‐states. These cities had a great need for raw materials, and this marks the beginning of large‐scale exploitation of Hit bitumen. This bitumen was traded at settlements along the Euphrates, where a large trade network was established. Hit bitumen entered the Persian Gulf at the turn of the second millennium (Dilmun period). Bitumen from Iraq (Mosul and Hit) became predominantly used in most settlements along the southern coast of the Gulf. During this period Iranian bitumen was also exported and this supply tended to increase, especially during the Partho‐Sasanian period. Dead Sea bitumen had its own exchange network, which was concentrated across present‐day Israel and Egypt where it was extensively used for mummification.  相似文献

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.  相似文献

Stone boiling is one of the principal cooking methods used by hunter-gatherer societies. The present paper proposes behavioral and organizational inferences as to how stone boiling was incorporated into hunter-gatherer subsistence practices through an examination of a shallow-basin hearth in an Early Magdalenian level (c. 15,500 14C B.P.) of El Mirón Cave, Cantabria (northern Spain). Exploratory analysis of spatial patterns of archaeological remains (bones, lithic artifacts, and fire-cracked rocks) and use-life analysis of fire-cracked rocks demonstrate that the hearth was used and maintained during visits of humans who preyed mainly on ibex and red deer near the site. The relative accessibility of these ungulates and cost-induced technology of stone boiling suggest the implication that stone boiling was employed to maximize the energy and nutrition obtained from carcasses of these game taxa under the circumstance of resource intensification.  相似文献

The comparative study of sedimentary fabrics in relation to archaeological fabrics in various levels of the sites of Cova Gran de Santa Linya (Middle and Early Upper Palaeolithic) and the Roca dels Bous (Middle Palaeolithic) has made it possible to analyse the formation dynamics of the deposits and determine the extent of disturbance of the archaeological levels by natural processes. To achieve this, diagrams and two- and three-dimensional indices were calculated from the azimuth and dip angle of natural clasts and artefacts. The results indicate that the sedimentary levels were formed mainly by planar fabric shape gravitational processes (low depositional angles), which differ notably from the archaeological fabrics they contain, characterised by a greater degree of isotropy. This difference in the fabrics would reflect human activity and indicates that the archaeological levels both in Cova Gran and Roca dels Bous have not been subject to significant natural modifications, and are preserved in situ.  相似文献

Bilbao's Art Scene and the “Guggenheim effect” Revisited   总被引:1,自引:0,他引:1  
The article analyzes the effects of the Guggenheim Museum Bilbao (GMB), adopting a new research perspective and trying to pursue the links between the museum and Bilbao's art scene. Until now, the impact of the museum has been analyzed from two different perspectives. The first focused on the urban development and regeneration aspects and the success of the museum as a tourist magnet and an image-making device. The second perspective concentrated on the direct economic benefits of the museum, i.e. direct returns and effects on the economy. The missing lens in previous analyses, however, was the impact of the museum on the city's art landscape, including the art support activities. In this context, the article describes for the first time in a detailed way how the GMB has contributed to the shaping and propulsion of changes on commercial and non-profit art spaces in Bilbao. Although it is clear that other factors may play a role, it can be asserted that the effects of the museum are not only limited to an increase in tourism or fiscal return, but also contribute to the development and spatial articulation of the local art scene and public support of the arts.  相似文献

This paper examines a recent dispute generated by the Queensland State Government proposal to build the Traveston Crossing Dam on the Mary River in southeast Queensland, Australia. It is particularly concerned with the ways in which interrelated issues of belonging, community identity, and social diversity were negotiated during the anti‐dam campaign. As an unusual alliance of farmers, environmentalists, urban retirees, some Aboriginal people and others, it takes a view of the anti‐Traveston Crossing Dam campaign as a fluid network of people and approaches the notion of community identity as the symbolic construction of similarity. Locally specific, the paper describes pertinent aspects of community politics in the context of rural socioeconomic change, and the mobilisation of heritage. With regard to local senses of belonging, it also discusses the involvement of Aboriginal people during the campaign. More broadly then, this paper attempts to make an ethnographic contribution to the study of environmental disputes and the politics of alliance in peri‐urban areas of settler‐descendant societies such as Australia.  相似文献
