Archaeological understandings of the Iron Age societies that developed on the East African coast and its hinterland have been transformed by exploration of locally produced ceramics. During the late first millennium, c. AD 600–900, sites across eastern Africa are characterized by ceramics known as early Tana Tradition or Triangular-Incised Ware, containing necked jars with incised decoration and a series of other jar and bowl forms in varying quantities. The recognition of this pan-regional tradition of pottery, known from an ever-growing number of sites, has been crucial in the reorientation of Swahili research to recognize the indigenous roots of the cosmopolitan coastal culture. This paper reports on the results of a ceramics project that has revisited excavated collections from a series of key ETT/TIW sites, analyzing sherds according to a single system and allowing true cross-site comparison for the first time. The results show regional diversity, in both form and decoration, particularly in the relative importance of the necked jar types that have come to stand for the early Tana Tradition more generally. While previous studies have hinted at regional diversity, such conclusions have been subsumed in discussion by the evident similarities between assemblages. Comparative results are here discussed against the background of previous research at the sites, and a series of conclusions about overlapping spheres of commonality are presented. Rather than critiquing previous work that has recognized this ceramic type, we seek to understand the remarkable distribution better by exploring its context and content.  相似文献

Domestication is an ongoing co-evolutionary process rather than an event or invention. Recent zooarchaeological and animal genetics research has prompted a thorough revision of our perspectives on the history of domestic animals in Africa. Genetic analyses of domestic animal species have revealed that domestic donkeys are descended from African ancestors, opened a debate over the contribution of indigenous aurochs to African domestic cattle, revealed an earlier and possibly exogenous origin of the domestic cat, and reframed our vision of African dogs. Genetic diversity studies and mapping of unique traits in African cattle, sheep, goats, pigs and chickens indicate adaptations to regional environmental challenges and suggest hitherto unknown and complex patterns of interactions both among Africans and with Southwest Asia and other Asian regions on the Indian Ocean. This article argues against the static perspective on domestication as invention and for viewing it as a dynamic, locally based and continuing process.  相似文献

The deposits of the Toruń Basin are dominated by a few-metre thick sand series which fill up buried valley-like depressions. In many cases they underlie the Weichselian till which builds up the ice marginal streamway (pradolina) terraces or they are exposed at the basin slopes. As the results of the geological and sedimentological studies, as well as of the dating of the deposits at the sites in the Toruń Basin indicate, the deposits include two fluvial series accumulated before the advancement of the Leszno Phase ice sheet, i.e. in Middle Weichselian and at the beginning of Late Weichselian. The oldest fluvial series connected with the Saalian Glaciation was found at the mouth section of the Drwęca Valley. The fluvial system of the Toruń Basin during Middle Weichselian and at the beginning of Late Weichselian developed in two phases of the sand-bed braided river. During the first one the river channel were dominated by large mid-riverbed sandbars, while during the second phase the water flow was smaller and, as a result, low transverse sandbars and two-dimensional dunes developed. Other active river channel also showed low-energy flows, more intensive meandering than in the case of the braided rivers, as well as sandy side-bars. Analysis of the rounding and frosting of the quartz grains indicate that the studied series of the Weichselian sandy deposits represent alluvia of a river which were fed from two diverse sources. The first one might have represented the alluvia of a warm river which transformed its load, while the other one might have mainly carried the underlying Quaternary deposits.  相似文献

Copper kettles, in high demand among indigenous communities of the Northeast/Great Lakes, became prominent items in the exchange repertoires of early Basque, French and Dutch traders. Kettles’ origin with these “Others” and its connection to a medium (copper) that had held symbolic significance for millennia led them to be used in an indigenous ‘metaphorical’ value regime influencing trade during the late sixteenth/early seventeenth century. An artisan living on the threshold of colonial encounter in Northern Michigan between 1470 and 1660 CE—having seen European goods but not having access to them—harnessed the mimetic faculty to make a small, miniature, ceramic imitation or skeuomorph of a European trade kettle. Rather than the sincerest form of flattery, I suggest this imitation was made to acquire the power of the original to fend off the colonial danger and to connect to this symbolic value regime. I suggest the “magic” of mimesis offered personal and organizational power in the indigenous Northeast/Great Lakes during early contact. This specific case speaks more broadly to how mimesis can provide a robust framework for exploring the material cultures of colonial encounter.  相似文献

There are many examples of buried rock surfaces whose age is of interest to geologists and archaeologists. Luminescence dating is a potential method which can be applied to dating such surfaces; as part of a research project which aims to develop such an approach, the degree of resetting of OSL signals in grains and slices from five different cobbles/boulders collected from a modern beach is investigated. All the rock surfaces are presumed to have been exposed to daylight for a prolonged period of time (weeks to years). Feldspar was identified as the preferred dosimeter because quartz extracts were insensitive. Dose recovery tests using solar simulator and IR diodes on both K-feldspar grains and solid slices taken from the inner parts of the rocks are discussed. Preheat plateau results using surface grains and slices show that significant thermal transfer in naturally bleached samples can be avoided by keeping preheat temperatures low. Equivalent doses from surface K-feldspar grains were highly scattered and much larger than expected (0.02 Gy to >100 Gy), while solid surface slices gave more reproducible small doses (mean = 0.17±0.02 Gy, n = 32). Neither crushing nor partial bleaching were found to be responsible for the large scattered doses from grains, nor did the inevitable contribution from Na-feldspar to the signal from solid slices explain the improved reproducibility in the slices. By modelling the increase of luminescence signal with distance into the rock surface, attenuation factors were derived for two samples. These indicate that, for instance, bleaching at a depth of 2 mm into these samples occurs at about ∼28% of the rate at the surface. We conclude that it should be possible to derive meaningful burial doses of >1 Gy from such cobbles; younger samples would probably require a correction for incomplete bleaching.  相似文献

Stable isotope analysis is increasingly used to gain insight in the configuration of Pleistocene ecosystems. The application of isotope analysis to Neanderthal and cave hyena bone assemblages has led to hypotheses about the niche differentiation between these species. Comparing isotopic data with archaeozoology analyses shows discrepancies between the results of both analytical methods. Here, the results of all northwest European stable isotope studies on Neanderthals are reviewed. The emphasis of the analysis is on a sample of sites from MIS 4-3 in southwest France. Causes of the discrepancy between archaeozoological and stable isotope results are discussed and hypotheses reconciling the data are proposed. Recommendations for further research will allow testing of the hypotheses and increase our understanding of the functioning of Pleistocene ecosystems.  相似文献
