Archaeological evidence as well as textual sources leave no doubt about Alwa's (Alodia's) intense transcultural connections, further corroborated by understudied overseas glass bead imports found there. This paper presents results of an analysis of 23 glass beads from Soba, the most prosperous capital of medieval Nubia. Compositional analyses using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) have identified glass belonging to a number of broad compositional groups. Three samples were made of soda lime low-alumina glass produced in the Middle East (v-Na-Ca) and Egypt (m/v-Na-Ca). The remaining beads were made of two types of mineral–soda high-alumina glass (m-Na-Al) North Indian in origin. The results of this study provide new evidence for the provenance and chronology of glass beads available in medieval Soba and Northeast Africa, and contribute new data to research on trade contacts of that time.  相似文献

Results of OSL dating and sedimentary studies from the profile of the low alluvial terrace of the middle Warta River are presented. The samples were dated using the single-aliquot regenera-tive method. Dating was used to establish a timing of the Weichselian Late Glacial events in the river valley environment. Stable conditions on the floodplain are expressed by the deposition of organic-rich series radiocarbon dated at 12 900-12 600 cal BP and 11 600-10 770 cal BP. Samples for OSL dating were collected from the mineral material deposited during the intensification of flood events during the Weichselian decline. The results obtained for the alluvia range from 12.78 ± 0.62 ka b2k to 14.33 ± 0.74 ka b2k. Sedimentological criteria allowed to distinguish between particular flood events. Overestimation of OSL ages is probably a result of rapidity of environmental changes in that time.  相似文献

ABSTRACT

The Ober-Ost administration instated in 1915 covered a fragment of the former Grand Duchy of Lithuania; a territory contested by Germany and Russia, inhabited by a nationally and religiously diverse society, with the Polish-Jewish city of Wilno as its central point. The German policies exploited the national aspirations of both the Lithuanians and the Belarusian leaders to dissolve the former Polish-Lithuanian Commonwealth. Contrary to the Belarusian leaders focused on short-term benefits, the Lithuanian politicians proved more resourceful in using the seemingly pro-Lithuanian and pro-Belarusian policies towards obtaining their own nation state. The Germans discriminated the Lithuanian Poles in terms of rights to political activity, even when conducted without subsidies from the occupier. The disunity with the local society progressed and benefited the supporters of Polish national policies, however few in Wilno in 1915. The German authorities successfully pushed the Lithuanian Poles, so far seeking consensus with other local communities, towards merging with the post-war Polish state announced by the Act of 5th November 1916. The Germans backed the creation of small, interdependent Lithuanian and Belarusian states. The Lithuanians however issued a second declaration of independence (16.02.1918), thus becoming the only ones to benefit from Germany's military defeat.  相似文献

In southern England, the end of the Early Bronze Age is marked by the appearance of archaeologically visible farmsteads and field systems. This paper explores and critiques the widespread idea that these changes are the direct result of a need to intensify agricultural production. Such discussions have implicitly drawn on evolutionist images of economic maximization and environmental exploitation that do not sit easily with our knowledge of other aspects of Bronze Age society. In this paper, I shall consider economic change as a consequence rather than the cause of wider changes to the social fabric at this time. A review of the Early and Middle Bronze Age settlement evidence provides insights into how society became transformed over the period and begins to hint at some of the reasons why subsistence practices changed so visibly.  相似文献

ABSTRACT

Differentiating between charred and uncharred plant remains may appear straightforward but for some taxa (here fat-hen, Chenopodium album type) can be very problematic. Recognition of the preservation state is obviously crucial for archaeobotanical data derived from dry, open-air sites. Fat-hen as a common weed, is also one of the most important components of a persistent soil seed bank. It is also a well-known food plant, gathered or cultivated. Numerous findings of fat-hen seeds in unclear states of preservation were noted in the Early Neolithic sites of the Linear Pottery culture in Kuyavia (N Europe). In previous studies such specimens were omitted as probably uncharred. Re-examination of Neolithic finds of fat-hen from that region showed the link of their abundancy with the earliest phases of the Neolithic occupation. The plant probably played an important role in the diet of the early Neolithic settlers there. It may indicate intensive use of local, open, fertile, probably alluvial areas. Distinguishing between ancient and modern specimens of that common weedy plant, producing large amounts of small, black, resistant seeds is thus very important, holding a great potential to shed new light on the origins of agricultural societies in this part of northern Europe.  相似文献
