This article attempts to follow the tradition established by Hintze and Elias in comparing several aspects of representative institutions throughout medieval Europe. It uses numerous recent case studies and a new more detailed examination of the Low Country sources and it tries to take into account the criticisms levelled at the rather unsophisticated generalizations of earlier scholars. Attention is given to the structure of the institutions, their actual working and their functions.Comparisons are made whenever the available information permits, if possible by quantification, although our information is often too vague and incomplete to permit this. A number of ideal types are formulated as a working hypothesis for further investigation, based on the social structures within which these types of institutions functioned. The essential variables were the extent of urbanization in a particular territory, the form of government and the economic and juridical situation of the nobles and peasants.  相似文献

Biocultural patterns surrounding the emergence of agriculture from 11 sites in the central Tombigbee River valley (500–1200 AD), 50–100 km west of the emerging Moundville polity, suggest that while food production may have alleviated some ecological stress, it came at a cost. Markers of childhood arrest indicate earlier weaning, likely creating a cycle of rising fertility and competition, but surviving adults appear better off following intensification. Health disparities at farmsteads, including more prevalent anemia, growth defects, lower limb infections, and accidental trauma, are consistent with increasingly competing demands of domestic and corporate modes of production. Although these agricultural settlements in the hinterlands were not severely compromised as predicted by a strictly top down model of provisioning, health risks assumed by farmsteads may have resulted from provisioning to centers and/or corporate lineages while simultaneously mitigating larger risks (e.g., raiding). The greater health risks assumed by farmstead females suggest that they had less control over production and decision-making than women buried at centers, while height and upper body strength at mound centers, in addition to rare but extreme trauma, point to identities that were mapped not only onto the landscape, but onto the bodies of men and women occupying elite spaces.  相似文献

The problems of interpretation of many overlapping species lists of fossil assemblages are discussed using the example of insect faunas from a late medieval farm site in southern Iceland. Numerical techniques were employed, principally those available within the CLUSTAN package, and it was concluded that a considerable refinement in interpretation was achieved. Such quantitative procedures are suitable for groups other than fossil insects but their employment cannot be regarded as a substitute for, rather than an adjunct to, a sound ecological approach.  相似文献
