The beginning of the Late Bronze Age in the Aegean has usually been thought to coincide with the start of the Eighteenth Dynasty in Egypt, and radiocarbon dates (which consistently suggest an earlier chronology) have been rejected by Aegean specialists because they do not agree with this view. Evidence from pottery is used to re-examine the links between the Aegean and Egypt, with the conclusion that the Aegean Late Bronze Age began during the Hyksos period.  相似文献

This article focuses on Finnish national identities because they expressed the shared experiences of newly established Finnish communities, and they were crucial in constructing a new nation. It also explores created images of the Finnish and Finland, as well as community construction in Republican China, especially after Finland gained independence in 1917. Another aim is to examine those Finnish political, cultural and economic activities that supported their identity construction in China. The specific emphasis will be on analysing the largest and sometimes cross-functioning Finnish groups in China: the governmental officials and the commercial community. By using qualitative methods, namely, discourse analysis and historical analysis, this study shows how the Finnish community created alternative, sometimes imaginative and frequently anti-imperialist national identities in the new Republican China. Indeed, by signing the Treaty Principles of Reciprocity and Equal Treatment, it was agreed that Finland and China ‘shall enjoy same rights, privileges, favours, immunities and exemptions which [might] be accorded to similar foreign agents in accordance with the principles of international law’. This article argues that Finnish aspirations were positively regarded by many Chinese, and they respected this quite unique national connection with Finland.  相似文献

In September 1968, one of the authors (P. Mayes), having been appointed Head of Mission by the British Ministry of Overseas Development to act as advisor to the Jamaica National Trust Commission, made recommendations which formed the basis for the establishment of the Port Royal Project. The Project is concerned with the excavation, conservation and presentation of 17th century Port Royal, which was founded in 1655 and destroyed by an earthquake in 1692 (see Fig. 1). For the purposes of archaeology the area was divided into three: the Archaeological-Historical Reserve, encompassing the protected underwater area and lands currently occupied by government facilities at the west end of Port Royal; the area in the centre of Port Royal which is protected archaeologically by modern housing and the area at the east end of Port Royal in which it was proposed that commercial expansion should be allowed on land held on lease from the Jamaican government. Work began early in 1969 in a section of this last area, which was threatened, at that time, by the construction of an hotel. This area was part of the shoal water section of sunken Port Royal (see below and Fig. 2). Since that date excavation headquarters and conservation laboratories have been established in the old naval hospital and the construction of a major museum, the first phase of the presentation programme, has begun.  相似文献

This paper is a statistical and geological study of the results of analysis of flint from British and West European flint mines, carried out by emission and atomic absorption spectroscopy. Groups of flint specimens were studied from each geographically separate flint mining area. Flints were analysed for a group of easily measured trace elements shown by previous work to be generally present. The ratios between the trace elements form a consistent pattern for each flint mine and statistically valid differences of pattern can be recognized between different flint mines. A geological investigation shows that the measured trace elements may be derived from clay minerals and explains geographical and statistical variation in the composition of flint in terms of its mode of origin in the chalk. An advanced statistical technique allows individual flint specimens of unknown origin to be attributed by their composition to one or other of the identified flint sources. The archaeological implications of this study are discussed.  相似文献
