This case-study is the first attempt to examine a commercial outpost in the Crusader Levant within the context of the commercial and colonial expansion of its mother-city and in direct relation to its particular features. The Venetian quarter in Acre in the second half of the thirteenth century provided the physical setting for the exercise of authority by the state and a solid base for the expansion of its dominion. The Venetian administration there implemented the strict regulation of commerce and shipping enacted in Venice in this period, including several rules stemming from the particular needs of Acre. Various families of settlers from Venice, nobles as well as popolani, can be traced for several generations; the grant of Venetian status to natives of the Latin kingdom of Jerusalem, Latins oriental Christians, and Jews, enlarged the size of the Venetian population in Acre. The fate of the refugees who escaped from the city in 1291 is the last topic to be examined. 相似文献

This editorial anticipates the conference Anthropology in the World by reflecting upon the influence of anthropology, and its limits, arguing that it is only by knowing where these limits are that we can be sure where and how it can best be judged. It is too, a call for unity, suggesting that in seeking to influence the external world, anthropology should unite across its sub‐disciplines, and in doing so a mutually‐beneficial exchange of practice, ideas and methodology will emerge. 相似文献

In 1985 a Neanderthal skeleton was found in the cave of Kebara in southern Mt. Carmel. Electron spin resonance (ESR) dates have been obtained on tooth enamel of gazelles found in layer X, just overlying the layer in which the skeleton was found. Assuming early uptake of uranium by the teeth, they yield an age of 60 ± 6 ka; assuming gradual, linear uptake of uranium yields an age of 64 ± 6 ka. Both age estimates are consistent with a previous estimate for the skeleton, based on TL dating of burnt flint, of 60 ± 4 ka. 相似文献
