ABSTRACT

This paper presents an overview of archaeological investigations conducted at Darien Bluff, McIntosh County, Georgia, over the past 75 years. The discovery of lost artifacts, missing excavation records, and several draft reports provided an opportunity to obtain a comprehensive overview of Spanish Mission period activity at the site of Mission Santo Domingo de Talaje, a primarily seventeenth-century mission that once stood on the banks of the Altamaha River. Included are archaeological and historical perspectives of the researchers who excavated the site and new interpretations by the authors that draw on recently relocated artifacts and excavation records.  相似文献

The negotiations between Norway and Russia, formerly the Soviet Union, in the maritime delimitation in the Barents Sea have been going on for more than 30 years. Despite a declared will on both sides to reach an agreement, the prospect of an early settlement seems remote. Formally the delimitation problem concerns the distribution of the important economic resources in the area, i.e. petroleum and fish. In practice, however, the strategic importance of the area and the impact of the international context on the bilateral relationship have played an important role in the negotiations. As a result, the parties clearly have different preferences for a solution. Because there is no practical need for a solution and because the parties do not see the boundary dispute as a strain on their mutual relations, the prospect of an early settlement is dependent on the political will of both sides to bring this long-standing conflict to and end.  相似文献

One of the characteristics of the cultural landscape of Svalbard is the abundance of remnants of Russian hunting stations, in the form of house ruins, graves, and large erected crosses. These are traces from Russian Pomors from the areas along the White Sea, who were hunting here over a long period of time - a period which the author will make an attempt to delimit in this article. It is known that the last Russian hunting expeditions to Svalbard were equipped from Archangel in 1851-1852. Far more controversial is the issue of the actual start of hunting by Pomors in Svalbard. This issue has been hotly debated among historians and archaeologists ever since the end of the nineteenth century.  相似文献

Abstract

This paper reports the discovery of the earliest evidence of domesticated wheat in the Crimean peninsula from the Ardych-Burun shell midden site, Ukraine. The Ardych-Burun site dates to middle of the 4th millennium cal b.c. For the first time, the chronology of a Ukrainian Chalcolithic period site has been established through direct radiocarbon dating of cereal grains retrieved from it. This discovery allows for a wider discussion of the chronology and geographical origins of domesticated plant species in Ukraine and the role the Caucasian corridor may have played in the spread of agriculture into eastern Europe. The presence of cereal crops in the southern Crimea enriches our understanding of the subsistence strategies of the coastal population, which was previously linked only with pastoralism, hunting, and the exploitation of marine resources.  相似文献

Abstract

Here we present a flexible, quantitative methodology for refitting handmade ceramics. Rather than analyzing the physical joins between sherds, we assess the likelihood that non-adjoining sherds of similar appearance are from the same vessel. The customary disregard of non-adjoining sherds in refitting experiments prompts us to address this issue. Using the Neolithic ceramic assemblage from Thirlings (Northumberland, U.K.) as a case study, we test several scoring systems for assessing the probability of two sherds pertaining to the same vessel. The utility of this approach is supported by the comparison of a set of percentage scores statistically verified using Spearman’s rank correlation coefficient. We conclude with a discussion of the contribution of the new method to post-excavation ceramic analyses, and its applicability to other assemblages.  相似文献

Obsidian has been noted at archaeological sites in the Midwest for over 160 years, although very few artifacts made from this material are recorded in archaeological contexts in Missouri. Background research revealed that only 16 obsidian artifacts from 13 sites had been documented from the state and that only 5 of the specimens had been geochemically analyzed and attributed to a source. Recent excavations at the Droste site (23PI1291), a Late Woodland period site in northeast Missouri, yielded two obsidian artifacts. The two specimens from the Droste site along with two previously unsourced obsidian artifacts from the Burkemper site (23LN104) and two from the Stapleton site (23HD110) were tested for trace element composition via X-ray fluorescence analysis. This article reports the results of these geochemical analyses, reviews the other obsidian artifacts reported from Missouri, and examines the cultural context and source of obsidian artifacts from other states in the upper Midwest.  相似文献

Eight prehistoric wells dug to a depth of ∼2 m below the modern ground surface were found in the alluvial sediments of McClellan Wash on Gila River Indian Community in southern Arizona. Charcoal from the sediments filling the wells yielded radiocarbon ages of ∼1000 B.C. The time in which wells were dug coincides with a period of general regional aridity and high ENSO activity in the American Southwest. Digging to access water may have occurred in response to period(s) of resource uncertainty, or as a logistical activity that engaged increasingly resource-tethered Late Archaic/Early Agricultural populations. These activities laid the foundation for agricultural practices that eventually became the dominant mode of subsistence in the low-lying areas of the Sonoran Desert.  相似文献

Abstract

This article concentrates on the ‘drug scare’ caused by the introduction of heroin to Greece in the inter-war period. It will first retrace the story of heroin’s introduction into the Greek drug scene and assess the reasons for its speedy diffusion among drug users. Following this, it will examine some central themes in the discourse on drugs and heroin in particular, such as the actual or projected harm caused to individuals, society, or the nation as a whole. Then the focus will shift to perceptions of heroin and its users, considering broader debates which circulated in Greek inter-war society, for example, the country’s identity and its position within two parallel and interrelated conceptual frameworks: traditional vs. modern and ‘East’ vs. ‘West’. The paper will conclude by addressing drug users’ self-representations that were influenced, to a certain degree, by the prevailing approaches to drug addiction.  相似文献
