The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.  相似文献

What can professional land managers gain by consulting with local communities? Scientific knowledge provides valuable insights into the causes of environmental change and the processes by which it occurs but often lacks a historical dimension. Recollections of local people can supplement both historical records and scientific understandings of cause and process to achieve a more comprehensive picture of change over time. However, the process of memory is tied to life experience and is highly selective. Any attempt to use oral accounts in constructing a picture of environmental change over time must also include an analysis of the process of memory itself. Drawing on oral histories with long term residents of the Tumut region of NSW, this paper explores the nature of local environmental knowledge and evaluates oral history as a source of information for understanding environmental history and the impact of changing patterns of land use.  相似文献

The management of archaeological heritage is complex and problematic for site identity and local culture. Inattention to the array of values of heritage sites leads to the supremacy of a number of them and provides a controversy story of the archaeological site in question. Any heritage management and interpretation effort should correctly identify the different values of the site. Indeed, there is a need to manage and interpret the sites in a way to address the connection between the sites-based values and the associated and surrounding features. In current heritage management practice, values and values-based management are considered to be one of the most important approaches for the management of archaeological heritage. This study aims to understand how the values of the archaeological site of Umm Qais in northern Jordan can be adequately managed as both a natural and cultural landscape. At issue are conflicting views over the different values, their meaning and their uses by the different stakeholders. This research focuses on the ways in which these values are managed and interpreted to the public and whether it is done properly and in a fair manner. The fieldwork study led to a more complex understanding of how conflicting perceptions of values of Umm Qais as a national heritage site by the different stakeholders have affected implementation of management and interpretation projects. The results presented here indicate that the heritage management approach from the case study of Umm Qais focuses specifically on values associated with the physical archaeological aspect of the site, while those associated with the historic neighborhood of the site are neglected. The interpretation of the site has frequently focused on certain aspects of values at the expense of others. Information and insights gained from this study and specific suggestions for changing approaches are considered with regard to potential impacts on the management of the archaeological site and with regard to the public in general.  相似文献

This article explores the extent to which formal network analysis can be used to study aspects of entanglement, the latter referring to the collective sets of dependencies between humans and things. The data used were derived from the Neolithic sites of Boncuklu and Çatalhöyük in central Turkey. The first part of the analysis involves using formal network methods to chart the changing interactions between humans and things at these sites through time. The values of betweenness and centrality vary through time in ways that illuminate the known transformations at the site as, for example, domestic cattle are introduced. The ego networks for houses across four time periods at the two sites are also patterned in ways that contribute to an understanding of social and economic trends. In a second set of analyses, formal network methods are applied to intersecting operational chains, or chainworks. Finally, the dependencies between humans and things are evaluated by exploring the costs and benefits of particular material choices relative to larger entanglements. In conclusion, it is argued that three types of entanglement can be represented and explored using methods taken from the network sciences. The first type concerns the large number of relations that surround any particular human or thing. The second concerns the ways in which entanglements are organized. The third type of entanglement concerns the dialectic between dependence (potential through reliance) and dependency (constraint through reliance).  相似文献

In an attempt to introduce concerns with social identities into the discussion and understanding of the making of what we call Paleolithic art, this article considers issues of gender, skill, apprenticeship, and tradition. We note that, as in every period of history, Paleolithic art can be seen as embedded in the society that studies it. Over the last 20 years, the research attention given to women in Paleolithic societies has grown considerably, leading us to ask what could have been the roles of women in Paleolithic art. On what criteria could we base a determination of those roles or of other social identities that were likely part of the making and viewing of Paleolithic art?Thanks to our microscopic analysis of engravings, it is possible to identify the skill level and expertise of the artists and thus to address the question of apprenticeship and how these techniques were transmitted. We observe many similarities that allow us to group together various works of art, sometimes from very distant sites, which indicate a movement of ideas, objects, and people. Are we talking about “imitation”? How can we define an “invention” within a social context strongly bound by traditions?  相似文献

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.  相似文献

The gender structures of the communities of the Late Neolithic and Copper Age in South East Europe have been firmly placed in a binary system by past archaeological analysis. The analysis of cemetery remains has indicated that binaries are expressed through differences in body position and the types of artefacts placed in the grave. However, re-evaluation of evidence from Durankulak cemetery on the Bulgarian Black Sea coast demonstrates that such interpretations may result from the imposition of a modern Western understanding of gender as binary based on sex; these assumptions can lead to the exclusion of data which points to more complex and varied gender relationships. This paper briefly discusses the problems in starting archaeological analyses from an assumed binary in both sex and gender. It is argued that any approach that starts with this binary is likely to be misleading, and that large-scale data sets, such as cemeteries, should be investigated using multivariate statistical techniques to uncover a variety of horizontal and vertical social categories and roles, of which gender may be a part. It demonstrates that in the case of Durankulak, while there are gender differences, there was a great deal of more complexity than a simple male/female division. Some artefacts are exclusively associated with male burials, while female graves have less variety in their assemblages.  相似文献

This article considers ways that representations of anthropomorphic imagery in the form of figurines from prehistoric village communities have been interpreted and provides a new framework for analyzing figurines. It has been long suggested that prehistoric figurines should be interpreted as representations of female gendered qualities related to ritual, fertility, and motherhood combined into a concept called “mother goddess.” The impetus for the adoption of this interpretation and evidential association with prehistoric figurine assemblages and bound to binary gender is briefly critiqued. The methodology for studying figurine assemblages presented here utilizes typological, archaeological, and comparative analysis and is cognizant of inherent ambiguities in the object biographies of the full assemblage. This study applies this methodology to a corpus of figurines excavated from sixth millennium settlements associated with the Halaf material culture. This approach is then operationalized with case studies of figurines excavated from Domuztepe (Turkey) and Chagar Bazar (Syria) as examples of engagement with those who conceived, made, used, and discarded them. The Halaf figurine corpus is shown as nuanced, displaying sexual difference and humanness on a spectrum from overt to ambiguous. Considered as a whole, the Halaf corpus is shown to have had mundane and mutable use lives related to embodied identities entangled with culture and community, unconnected to gender binaries, ritual, fertility, or motherhood.  相似文献
