The use of red pigments linked to burial practices is widely documented in the Iberian prehistoric record and very often it has been traditionally interpreted as a ritual practice entailing the utilisation of local raw materials (iron oxides). Some research works, nevertheless, have also detected the use of red pigments which can only be interpreted as allochthonous. The red pigments spread over a single inhumation in a monumental Megalithic tomb surrounding Valencina de la Concepción Copper Age settlement was studied by means of X-ray diffraction, field emission scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray microfluorescence, micro-Raman and Fourier transform infrared spectroscopies. This approach allowed characterising the red pigments as cinnabar, mixed with tiny amounts of iron oxides. The presence of cinnabar, a product that was necessarily imported, in a context of an exceptional set of grave goods, suggests that the use of cinnabar was linked not only to ritual but also to practices related to the display of social status.  相似文献

Numerous reports of successful radiocarbon dating of cremated bones have emerged during the last decade. The success of radiocarbon dating cremated bones depends on the temperature during burning and the degree of recrystallisation of the inorganic bone matrix. During cremation bones undergo major morphological and mineralogical changes which have raised some interesting questions and discussion on the origin of the carbon source in archaeologically cremated bones. Recent laboratory experiments reveal that the properties of the combustion atmosphere play a significant role regarding the source carbon in cremated bones. Thus radiocarbon dating cremated bones is potentially dating the wood used for the cremation fire. Here we compare a high precision radiocarbon dated human bone with an associated dendrochronological age from an oak coffin. We find that the age discrepancy between the dendrochronological age and the cremated bone of 73 ± 26 14C yr is best accounted for by the so called ‘old wood’ effect.  相似文献

The technological organization and lithic raw material procurement of Holocene hunter–gatherers have been topics of considerable interest in northern Tierra del Fuego Island. Ongoing archaeological investigations indicate that most of the rocks employed by native human populations came from secondary deposits of fluvio-glacial and marine origin. However, a primary geological source for two distinctive lithologies has been recently discovered near the Chorrillo Miraflores Valley (Tierra del Fuego, Chile). These raw materials became the focus of further research since one of them (a silicified tuff) has been identified in several archaeological sites of Tierra del Fuego. Some of these sites are located more than a hundred kilometers away from the source. A regional survey of potential lithic sources along with petrographic and geochemical analyses confirmed that the silicified tuff is only available at Chorrillo Miraflores. Here we present the technological analysis of artifacts manufactured on Miraflores silicified tuff that were recovered from the Argentine portion of northern Tierra del Fuego composed of Espíritu Santo and San Sebastian Capes. The role of utilitarian currencies in the prehistoric use of this lithology is assessed through the application of the Metcalfe and Barlow (1992) field processing model. The results show that this raw material may not have been exclusively selected for its flaking quality, although an alternative functional efficiency hypothesis is also introduced. Finally, its spatially restricted availability as well as unique macroscopic aspect suggests its selection and use may have been mainly influenced by social factors.  相似文献

Abstract: The “Middle East” is a readily accepted geographical category throughout much of the world. However, within this ambiguous geographic entity, both the term and the idea of the “Middle East” are often rejected as western‐imperialist constructs. Through a critical examination of an extensive sample of maps produced within several Arab states of the “Middle East”, I found that the regional designation “Middle East” is nearly nonexistent, while the Arab Homeland is unequivocally a more common regional category. However, the “Middle East” did occasionally appear in a few maps. This paper provides an explanatory examination of the normative cartographic discourses in this region, and more focused analysis of the atypical maps of the “Middle East”. My analyses render unique insights into how the “Middle East” is both contested and re‐created from within a western‐imperialist defined region.  相似文献

In this paper we trace one pervasive expression of hegemonic New Zealand national identity that developed around the sport of mountaineering from the 1880s, culminating in Sir Edmund Hillary's historic first climb of Mount Everest in 1953. The image of the masculine mountaineering hero, developed on and around New Zealand's highest peak, Mount Cook, is, however, inherently unstable, and we focus on two sites of potential disruption. First, we examine the experiences of white mountaineering women on Mount Cook. These women both embraced the masculinist identity of hero and destabilized it. Women's mountaineering points to the active and complex construction (rather than simple reproduction) of imperialisms, nationalisms and masculinities. Second, we examine the role played by the Hermitage Lodge situated at the base of Mount Cook. Narratives about mountaineering too often ignore the huts, lodges, the places of staying behind. The roles performed by women (and some men) who never had the opportunity and/or the desire to climb but instead 'kept the home fires burning' and supported the efforts of others can be examined as a way of productively challenging the entrenchment of national identity around the masculine mountaineering hero.  相似文献

Zooarchaeological analyses often rely on bone fragmentation, cut marks, and other taphonomic indicators to bolster interpretations of resource intensification that are based on observed changes in prey types and frequencies. While these taphonomic indicators are assumed to be good proxy measures of processing effort, this assumption is based on inadequate actualistic data and analysts often conflate one or more taphonomic indicators as manifestations of the same process. In this paper, we present zooarchaeological data from two villages occupied by Central African forest foragers with very different foraging efficiencies. These data provide the first case where known disparities in diet breadth and foraging efficiency are matched with prey assemblages and taphonomic attributes. Observational and quantitative data show differences between the villages in diet breadth and access to high-ranked prey, but specific taphonomic indicators such as cut mark distribution and intensity do not match predictions generated from models of resource intensification. We propose that linking different taphonomic processes to resource scarcity and intensification can provide powerful adjunctive information. However, because different processing outcomes may be associated with different kinds of resource intensification in response to different kinds of scarcity, we need to strengthen the validity of purported taphonomic indicators with more rigorous independent studies.  相似文献
