Due to their problematic stratigraphy, shell middens have traditionally been excavated by artificial stratigraphical cuts. This approach has often led to the obliteration of the original depositional sequence, removing important information regarding depositional and post-depositional processes, and human frequentation. Since the 1970s, an Argentinian team has been excavating archaeological shell middens in the Beagle Channel with a detailed stratigraphical approach, based on the excavation of actual depositional units (peeling), rather than artificial cuts. In the 1980s, Spanish archaeologists joined the Argentinean team and launched a series of new projects involving the excavation of ethnohistorical Yamana fisher-hunter-gatherer sites. The first excavated midden site was Tunel VII, from which two monolith columns of about 50 cm each (C11 and C12) that spanned the whole stratigraphy were extracted. The two columns were consolidated with resin, and two series of thin sections produced to corroborate stratigraphical observations made in the field, and to verify hypotheses related to the formation of archaeological shell midden sites. We present here the first results obtained from the microscopical observation of seven thin sections from column 11 (West column), extracted from a portion of the profile originally described as corresponding to the hut entrance and associated floor. The observation of microscopical features invisible in the field has provided supplemental information about the depositional and post-depositional processes affecting shell midden sites. We have also preliminarily defined a number of micromorphological characteristics identifying human activities such as discrete shell deposition events, phases of preparation of the hut floor, and compression by repeated trampling. Finally, we have explored the possibility of establishing some guidelines to characterise the length and character of frequentation phases of the site previous to its final abandonment at the beginning of the 20th century.  相似文献

The research concerns the Tiber delta area, about 3 km far from the present seacoast, where the remains of the ancient harbour of Rome are located. In 42 AD, Claudius started the construction of the harbour and Nero completed it in 64 AD. Then, the emperor Trajan went on to add a hexagonal basin to the former structure, which had gradually silted up. The imperial harbour was connected to the Tiber River and ultimately to the city of Rome through the Trajan channel. During the imperial period, most of the supplies imported from the Mediterranean provinces reached the city of Rome through Portus.  相似文献

“吃讲茶”:成都茶馆、袍哥与地方政治空间   总被引:1,自引:0,他引:1  
作为公共空间的茶馆成为袍哥的活动中心,他们在那里联络、聚集和开会,成为袍哥社会网络的一个重要部分。袍哥在茶馆里活动形成了他们独特的语言和行为,"摆茶碗阵"便是他们经常使用的联络方法。茶馆作为地方政治空间可以表现在很多方面,不过,"吃讲茶"仍然是最为典型和最具代表性的活动,这个实践显示了市民的相对自治状态,他们试图在没有官方介入的情况下解决冲突,说明一种国家之外社会力量的存在。  相似文献

Venice lagoon formed part of a network of inland waterways used for navigation in the northern Adriatic, an almost continuous system of lakes, river‐mouths and canals, at least partly pre‐Roman in origin. The fossae which cross the present lagoon are the continuation of a complex system of natural watercourses and artificial canals between Ravenna and Aquileia. Two Roman buildings discovered on the present San Felice canal could be interpreted as providing navigational assistance at points linking the sea and inland routes. © 2009 The Authors  相似文献

Before 1644, the Manchu rulers pursued a deliberate policy of alliances with the southern (later “Inner”) Mongol tribes. In the 1630s the system of treaties and alliances gave way to the creation of the League-Banner system, the jasaq system, and the Lifan Yuan. The new territorial and political organization meant that the southern Mongols, while retaining a degree of autonomy, became subjects of the Qing dynasty. This essay explores the historical circumstances of the transformation of the relationship between Manchus and Mongols from partnership to subordination. It also aims to explain the political principles deployed by the Manchus in the redefinition of their relationship with the Mongol elites. More specifically, the essay proposes that the new forms of administration of Inner Mongolia stemmed from a condition of “tutelage.” Tutelage was not simply imposed by the Manchus upon their erstwhile allies, but actively sought by Mongol aristocrats in the context of the intra-Mongol wars carried out by the Čaqar leader Ligdan Khan.  相似文献

This study discusses the existence of a variability recorded in lateralization indexes of proximal microburins, a by-product of the individual manufacture of microliths, in a sample of Sauveterrian sites from the Italian Eastern Alps. At first glance, such variability may appear to support the existence of customary handling, pertaining perhaps to an ensemble of normalized technical procedures accomplished by the members of the human group regardless of site type, context and economic activities. However, plotting the patterns in lateralization index against the regional Sauveterrian chrono-cultural sequence reveals a diverse correlation emerges and indicates how the early settlement phase involved greater functional differentiation among sites used by selected human groups compared with the successive phases, when this pattern vanishes. This trend may correspond to the decrease in lateralization observed on skeletal markers from the Upper Paleolithic to the Mesolithic, linked to the change in technological models and techniques employed in food gathering. The implications of this research at different levels are also discussed.  相似文献

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, 14C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.  相似文献
