The physical appearance of the Merovingian villa has been ignored by most archaeologists and historians, largely because of the paucity of information. Three radically different images can be found in the sparse literature; something akin to a Roman villa, a forerunner of the medieval castle, or a village settlement such as the excavated site of Warendorf, Germany, to which a number of analogous sites have been found in the recent past. This article argues for the continuity of Roman traditions, if not the actual physical buildings. In particular the absence of fortification is discussed. Traditionally, violence and the development of castles are accepted as cause and effect, yet endemic insecurity did not give rise to a Merovingian castle. The common enclosures of Merovingian villas, far from being defensive, are seen as having symbolic meaning which was actively employed to define propriety, legal rights, and social relations. The maintenance of peace and personal safety depended on the adequate understanding by individuals of local politics and the ordering of their social world; an understanding expressed in the physical world of architecture.  相似文献

Ground-edged artifacts were an important part of the Australian Aboriginal toolkit. They had practical day-to-day uses, but some had symbolic and social values that led to their movement across great distances. Australian provenance studies document long-distance Aboriginal exchange systems extending over hundreds of kilometers. The size and complexity of exchange systems and social networks were contingent upon resources and the productivity of a region's environment. Along the fertile, well-watered lands east of the Great Dividing Range, movement of objects may have been geographically more circumscribed than in drier areas to the west. One hundred and twenty-one mafic, ground-edged artifacts from the New South Wales (NSW) Central Coast and 368 geological specimens from potential sources were non-destructively analyzed by portable X-Ray fluorescence spectrometry. Results indicate the existence of a well-used basalt source within the region at Peats Ridge-Popran Creek as well as multiple local and non-local sources up to 430?km from Mangrove Mountain on the NSW Central Coast.  相似文献

Abstract

In France and Europe today, claims arise defining so-called Muslim and European ‘worlds’ and labelling them irreconcilable. These claims ignore the intertwined history of France and North Africa. When the six founding members of the European Economic Community (EEC) signed the Treaty of Rome, French administrators still considered Algeria to be a constituent part of France, despite the ongoing war. The Algerian question was central to negotiations for the Treaty of Rome and during them, French officials attempted to inscribe Algeria within the founding documents of the European project through a policy of ‘Eurafrique’. Their partners, eager for France’s signature on the Treaty, accepted a vision of integrated Europe with borders crossing the Mediterranean. This decision raised thorny issues in the months and years to come, first in debates of how or even if the Treaty could be implemented overseas, then when independent Algeria attempted to define its relationship with the EEC. These episodes of negotiation and interaction reveal the centrality of the question of empire to the foundations of integrated Europe.  相似文献

Abstract

Using complementary behavioural and population ecological models, we explore the role of production risk, normal surplus and inter-annual food storage in the adaptations of societies dependent on seasonal agriculture. We find that (a) household-level, risk-sensitive adaption to unpredictable environmental variation in annual agricultural yields is a sufficient explanation for the origins of normal agrarian surplus and, consequently, of household-level incentives for inter-annual food storage; and, (b) at the population level, density-dependent Malthusian processes tightly constrain the circumstances under which this same mechanism can be effective in smoothing inter-annual fluctuations in household food availability. Greater environmental variation and higher levels of fixed set-asides such as seed requirements or transfer obligations to political authorities lead to more severe, periodic famines; however, outside of famine events, these same factors improve average population welfare by suppressing population density to levels at which Malthusian constraints have lessened impact. The combination of behavioural and population ecological modelling methods has broad and complementary potential for illustrating the dynamic properties of complex, coupled human–natural systems.  相似文献
