Marriage was obviously an important institution to the late medieval aristocracy. Almost all of the peers between 1350 and 1500 married: all but seven did so at least once, and 144 of the 424 peers (or 34 percent) married two or more times. Since marriages were for political and economic reasons, as much or more than for personal ones, we find that many of them were contracted within the forbidden degrees of kinship and affinity, by dint of an ecclesiastical dispensation. Some dispensations were issued before the marriage, while others — usually carrying some sort of penance — came afterwards. Few proposed marriages were actually repressed or prevented by the Church. But there is also considerable evidence for affection and partnership within a marriage. Husbands who died first usually left considerable personal goods to their widows. They often made them executrixes and spoke of them in terms of trust and continuing responsibilities. Though there is no question that marriage at first was more business than pleasure, qualitative data show that it often became a satisfactory personal relationship and that it offered considerable scope for sentiment and cooperation.  相似文献

Empirical tests of resource-intensification models argue for diminishing foraging efficiency among hunter–gatherers in California over the past 2000 years (Basgall, 1987,Research in Economic Anthropology9,21–52; Broughton, 1994aJournal of Archaeological Science21,501–514; 1994bJournal of Anthropological Anthropology13, 371–401). The evidence for this long-term trajectory consists of decreases in the abundance of large, high-ranked prey in archaeofaunal assemblages. This paper presents faunal data from Fremont structural sites in the eastern Great Basin and Northern Colorado Plateau as an additional empirical test of resource intensification patterns and compares them to trends in California and the American Southwest. The measure of resource efficiency used is the artiodactyl index (following Broughton, 1994ab), a tool derived from prey choice models of optimal foraging. Faunal data from Fremont structural sites argue that (1) foraging efficiency declined during the Fremont period, and (2) this decline was due to population growth.  相似文献
