This article examines the motivations, institutions and processes involved in colonial knowledge formation through a study of the missionary William Burton. It considers Burton’s work on the Luba of Katanga in relation to the practices of Belgian colonial science and Anglo‐Saxon social anthropology. The essay discusses why missionaries engaged in ethnographic research when they were so intent on changing the customs and beliefs they described and why Burton in particular did not get the recognition he deserved as an authority on his subject. The article charts Burton’s shifting attitude toward the Luba, showing how he moved from an aggressive intrusive mode of research to a position of greater sympathy as he came to consider their cultural riches through study of language, proverb and folklore. Consideration of the second phase of Burton’s research opens up discussion of the missionary origins of the disciplines of African theology and African religious studies.  相似文献

The role of coastal resources in the subsistence strategies of Palaeolithic human populations has only recently become an important topic in Old World archaeology. Information on the exploitation of these resources, both as foodstuffs and symbolic elements, can be used to infer the emergence of modern human behaviour as well as to track the diversification and intensification of human diet over time. The excavations carried out at El Cuco rockshelter, located in northern Spain have provided evidence for the exploitation of marine resources during the Early Upper Palaeolithic. The accumulation of Patella shells at El Cuco provides the largest accumulation and the first clear evidence of collection and consumption of molluscs during the Aurignacian on the Atlantic Façade of Europe. A deposit of ornamental shells appeared in a very homogeneous context dated to the Gravettian, suggesting that the shells belonged to the same item. The analysis of this evidence has allowed us to conclude that marine resources were systematically used at least from the beginning of the Upper Palaeolithic in the region. However, a comparison with the Mesolithic shows that intensive shellfish gathering did not occur until the end of the Upper Palaeolithic. Regarding the ornaments, it is interpreted that the identified shell beads were used as social or personal status markers.  相似文献

The “North Atlantic Ice-Edge Corridor” hypothesis proposes that sometime during the Last Glacial Maximum, roughly 26,500–19,000 years ago, human populations from southern France and the Iberian Peninsula made their way across the North Atlantic and colonized North America. A key element of that hypothesis is the apparent similarity between stone-tool-production techniques of Solutrean peoples of Western Europe and Clovis and purportedly pre-Clovis peoples of eastern North America, most especially the supposed intentional use of “controlled overshot flaking,” a technique for thinning a bifacial stone tool during manufacture. Overshot flakes, struck from prepared edges of the tool, travel across the face and remove part of the opposite margin. Experimental and archaeological data demonstrate, however, that the most parsimonious explanation for the production of overshot flakes is that they are accidental products created incidentally and inconsistently as knappers attempt to thin bifaces. Thus, instead of representing historical divergence, overshot flakes in Clovis and Solutrean assemblages mark convergence in the use of the same simple solution for thinning bifaces that produced analogous detritus.  相似文献

Australia contains some of the world's richest and apparently longest traditions of rock pictographs. Dating this art, however, has been problematic, with few ‘direct’ and reliable dates of Pleistocene or early Holocene age having been obtained from visible, representational imagery. This paper critically reviews the evidence for the antiquity of pigment rock art in Australia by examining the various dating techniques employed. The accurate and reliable dating of rock art worldwide is crucial to understanding the evolution of modern human symbolism and whether cognitive modernism came about after, rather than with, the first signs of full biological modernism; understanding the pitfalls and devising proper methods are crucial prerequisites. Towards these ends, this paper reviews the results and techniques that have been employed to date the apparently earliest known pictographs in Australia.  相似文献

India has one of the world's largest and most significant bodies of rock paintings and engravings, yet not a single rock art site or image has been directly and accurately dated using radiometric techniques. Here we report on results from the Billasurgam Cave complex near Kurnool in southern India. Although this cave complex has been investigated archaeologically since the late 1800s, it was not until 2008 that a large petroglyph, consisting of the remains of three nested diamond designs on a stalactite, was noted. In order to determine if this petroglyph had been made recently, flowstone was sampled from on top of and below the engraving. Radiocarbon dating revealed a mid-Holocene age of about 5000 cal BP for the petroglyph, but we cannot rule out the possibility that the engraving is several centuries younger. Similar nested diamond designs at some rock painting sites and on a chert core elsewhere in India have been assumed to be Mesolithic. Our result is consistent with this hypothesis, although we note that it also consistent with the creation of the petroglyph in the early Neolithic. We conclude that the Billasurgam engraved diamond design was probably made by Mesolithic foragers of the Kurnool region and is the oldest surviving form of rock art yet directly dated in southern India.  相似文献

Explaining how the monumental statues (moai) of Easter Island were transported has remained open to debate and speculation, including their resource expenditures and role in deforestation. Archaeological evidence including analysis of moai variability, particularly those abandoned along ancient roads, indicates transport was achieved in a vertical position. To test this proposition we constructed a precise three-dimensional 4.35 metric ton replica of an actual statue and demonstrate how positioning the center of mass allowed it to fall forward and rock from side to side causing it to ‘walk.’ Our experiments reveal how the statue form was engineered for efficient transport by a small number of individuals.  相似文献

Dame Margery Perham, acclaimed as the foremost academic expert on British colonial administration, also gained much experience and showed much interest in its French counterpart. Her thoughts on this, however, were never published in her lifetime. This article, based her diaries (published posthumously under the editorship of the article's author) and other previously little-known material, reconstructs her views on French colonial rule and how she felt the two colonial services compared with one another. It also summarises the author's own perspectives on the latter issue.  相似文献
