Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ13C values surprisingly similar to those seen in marine fish. We propose a model, based on δ13C and δ15N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.  相似文献

In Guatemala local perspectives on heritage often remain unheard. In this paper a case study is presented to show the complex relationship between the highland site of Iximche’ and Tecpán, an Indigenous community nearby. Although Iximche’ is of little importance to the local economy, its significance is derived from its role as a field for different kinds of social and religious interactions. Traces of a spiritual relationship to this place can be dated back to the colonial period and today Maya from all over Guatemala go there to perform ceremonies. The place has also become a focal point of identity constructions for locals, Pan Mayan activists and the nation itself. The ruins of Iximche’ play an important role in the construction of collective memory which also includes ideas coming from external players such as Christian churches, the national government, Mayan activists, and archaeologists as well.  相似文献

During the past decade research into the German Final Paleolithic and Mesolithic has experienced an important revival. One clear sign of this renewed interest in the periods are the annual meetings of the Arbeitsgruppe Mesolithikum (Mesolithic Working Group) which have taken place every spring since 1992. At these meetings, which take place at changing venues, topical themes of Final Paleolithic and Mesolithic interest are presented by informal lectures and it is also possible to study regional collections (artifacts, raw materials) at first hand. Numerous contributions were subsequently published together in one volume (Conard and Kind (1998) Aktuelle Forschungen zum Mesolithikum/Current Mesolithic Research, Mo Vince, Tübingen). The present paper intends to complement that collection of papers with a synthesis of developments and perspectives and to present recent research highlights in the German Final Paleolithic and Mesolithic, together with a comprehensive bibliography, to a wider international audience.  相似文献

Beginning with the first travelogues of the late 1890s, the film and tourism industries collaborated both directly and indirectly to shape representations of North America’s western landscape and its people. These non-narrative motion pictures intersected with the rise of mass consumerism, modern tourism, the forces of imperialism and colonialism, as well as industrialized forms of transportation. In particular, railroad travel films from the Canadian Pacific Railway Company and the Northern Pacific Railway Company transformed motion-picture goers into armchair tourists, exposing audiences to the scenic wonders of the West. These transcontinental railroads, themselves products of nation-building initiatives, competed against one another to increase passenger traffic by marketing the sublime and often overlapping landscapes of the American and Canadian Wests as potent nationalist and unifying symbols that heralded each country’s uniqueness.  相似文献
