Research on the cargo of glass in the Roman ship Iulia Felix, wrecked off the town of Grado (province of Udine, North Italy) in the first half of the 3rd century AD and composed of recycling cullet carefully selected for colour and type, provided much information on Roman glass production technology. A combined approach, involving analytical, statistical, and archaeological evidence, included chemical analyses (X-ray fluorescence, electron microprobe), which indicated that the coloured samples were all soda-lime-silica in composition, with natron as flux, although cluster analysis identified many compositional groups. Comparisons among the compositional groups of the colourless glass, previously studied, and those of coloured glass showed that the production technologies of the colourless glass vessels constitute two well-defined technological end-members, also related to group types, into which those of the coloured glass samples fall. In particular, coloured glass samples—all bottles, low-status vessels—were produced with mainly beach siliceous-feldspar-calcareous sand. However, unlike the colourless type, strict control of raw materials and decolourising processes was not adopted, and recycling was also practised, as demonstrated by the Sb2O3, Cu and Pb patterns. In this context, a “recycling index” (RI)—[(Sb2O3)X/(Sb2O3)Ref] * 100—is proposed here for the first time, in order to quantify the extent of recycling of antimony colourless glass in the batch. RI is valid for glass containing abundant Sb from an end-member of colourless glass. In conclusion, although it cannot be stated unequivocally that the identified compositional trends are related to different production centres or different raw materials, the strong evidence of compositional variability among all the Iulia Felix glass samples, both colourless and coloured, supports the dispersed production model for Roman glassware and the common practice of recycling in Roman imperial times, especially for low-status vessels.  相似文献

An ethno-archaeological study of the people of Thongjao village considered to be one of the ancient pottery makers in Manipur provided a detailed account of the techniques and procedures of pottery making. The present study attempts to bridge the gap between the present ethnographic account and past archaeological account in respect of the ceramics of Manipur by drawing similarities between the Thongjao village and prehistoric ceramics of Manipur on the one hand and by making analogical interpretations of the latter on the basis of parallelism that exists between the two on the other. This study also highlighted the use of raw materials and their techniques used in making pottery and their prehistoric similarities in respect of their composition. The paper studies the different types of pottery found in this village and also reveals the socio-cultural association of the people, changes and continuity.  相似文献

Significant political and economic developments among the Chumash of southern California were catalyzed in part by the emergence of an intensive, specialist-driven shell-bead industry during the second millennium CE on the Santa Barbara Channel Islands. The production of millions of beads depended in turn on the availability of lithic microdrills of standardized form and materials. Channel Islanders quarried a particular stone type, a blocky Monterey Formation chert, from multiple outcrops situated close to the eastern shores of Santa Cruz Island. Rich archaeological assemblages document the lithic and shell byproducts of these intertwined production systems, each of which endured for several centuries (CE 1150–1819). Islanders invariably chose Island chert for making microdrills: hundreds of thousands of specimens recorded to date are of this material. Furthermore, nearly every microlith in all of Chumash territory (post CE 1150) was produced on the islands; the large populations on the mainland did not participate in microlith making or bead making after CE 1150–1200. We argue that this pattern had its roots not only in the patchiness of key resources and shifting regional social relationships, but also in the physical properties of available raw materials. Here we experimentally assess the properties of Santa Cruz Island chert alongside three important mainland raw materials—Grimes Canyon fused shale, Coso obsidian, and Vandenberg chert—that potentially could have been tapped to make microliths. We test the proposition that Island chert outperforms other lithic materials in drilling efficiency and drill use life. Our experimental results from 108 drilling trials reveal sharp distinctions in performance characteristics across the four materials. We infer that the process by which Islanders became the more-or-less exclusive manufacturers of shell-bead currency in southern California was facilitated by both the efficacy and physical properties of the Island cherts and the propitious locations of the outcrops.  相似文献

This paper presents a method for estimating edge length from flake dimensions. Comparison of estimated values with data from measured flake edges demonstrates the robusticity of the method. Building on the work of Braun (Braun, D.R., 2005. Examining flake production strategies: examples from the Middle Paleolithic of Southwest Asia. Lithic Technology 30, 107–125; Braun, D.R., Harris, J.W.K., 2003. Technological developments in the Oldowan of Koobi Fora: innovative techniques of artifact analysis and new interpretations of Oldowan behavior, in Mora, R., de la Torre, I. (Eds.), Oldowan: Rather More than Smashing Stones. Treballs d’ Arqueologia 9, pp. 132–144) this estimate is used to generate an edge length to mass value for complete flakes—taken to be a proxy for flaking efficiency. It is shown that this value is useful in tracking the onset, variability and decline of a well known technological phase—the Howiesons Poort of South Africa. The results suggest that the Howiesons Poort was a time in which flaking efficiency was emphasised. Furthermore, comparison of upper limits of edge to mass values for different raw materials may provide an insight into changes in raw material selection.  相似文献

The Women's National Basketball Association is a professional women's basketball league that is notable for constructing a heteronormative ‘family friendly’ self-image while maintaining a sizable following of lesbian fans. This article examines this apparent contradiction through two case studies: a kiss-in protest by a group of New York WNBA fans, Lesbians for Liberty, and experiences by Minnesota Lynx lesbian fans of the marketing tactics and daily practices that regulate WNBA game spaces. By highlighting the socio-spatiality of the WNBA venue, it becomes clear how heteronormativity is naturalized, as well as accepted and resisted by lesbian fans in both New York and Minnesota. An overt act of resistance, however, failed to encourage the WNBA to reconsider its policies: the Liberty kiss-in, by situating lesbians as a counterpublic, foreclosed the range of attitudes held by lesbian fans. Moreover, as Minnesota Lynx fans demonstrate, WNBA spaces feel ‘safe enough’ to many lesbian fans. As a result, there remains a contest over the meanings and practices that define WNBA landscapes. To date, however, normative heterosexuality has contained the presence and visibility of the lesbian fan.  相似文献

Summary.   At the Bronze Age tell of Százhalombatta, Hungary, techniques used for making pottery echo those used in other media. Pottery and architecture have a close relationship. Not only were both made of clay, but methods of making pots echo those used for building. Similarly, pottery and metalwork share common themes and technologies for working with clay and bronze. Since choices made by potters are not solely confined to the environment, raw materials and tools, but are also socially and culturally defined, by implication the transfer of know-how must be situated within social networks between people. This paper considers how the identification of technical relationships between different media at Százhalombatta can be used to explore social relations in Bronze Age society, thereby suggesting relationships that work on both technical and social levels.  相似文献

Large debris flows have destroyed the infrastructure and caused the death of people living in the Moxi Basin (Sichuan Province, Southwestern China). Inhabitants of the Moxi Basin live on the flat surfaces of debris-flow fans, which are also attractive for farming. During the monsoon season debris flows are being formed above the fans. Debris flows can destroy the houses of any people living within the fan surfaces. In order to prevent the adverse effects of flows, people plant alder trees (Alnus nepalensis) at the mouths of debris flow gullies running above debris flow fans. Alders are able to capture the debris transported during flow events. Trees are well adapted to surviving in conditions of environmental stress connected with abrupt transport and deposition of sediment from debris flows. Numerous wounds, tilting and bending of alder trees caused by debris flows only very rarely cause the death of trees. By dating scars and dating the time of alder tilting (through the analysis of annual rings), we have determined the frequency of debris flows occurring at the mouth of the Daozhao valley. In 1980–2012 within the studied debris-flow fan and the Daozhao gully, 2 large debris flow events occurred (1996, 2005) and some smaller events were probably recorded every 2–3 years.  相似文献

Wood exposed to a heat source can be transformed into charcoal if subject to conditions of carbonisation (in the absence of air) or charring (in restricted air). Charcoal recovered from archaeological sites can yield fundamental information to our understanding of human economic and cultural development over time and (ecological) setting. This work describes the morphological (anatomy, degree of shrinkage), physical (reflectance) and chemical (elemental, molecular composition) properties of charcoal in relation to heat source and wood variables. In this study charcoal and charcoal fuel were experimentally produced whereby temperature (160–1200 °C), time of exposure (2–1440 min), heating rate (high and low) and wood type (angiosperm and conifer) were varied. The results show that charcoal, often described as an inert, black material, has different chemical and physical properties in relation to the investigated variables. By using these different properties it is possible to distinguish between the different types of fires (domestic and industrial) exploited by humans in the past. Morphological analyses and reflectance measurements are effective tools for this purpose and can be used in wood exposed to temperatures of 300 °C and above—temperatures which are relevant to archaeological research. Angiosperm and conifer wood react in different ways when exposed to heat and thus the taxonomic identity of archaeological material needs to be known. Chemical analyses can be used for wood exposed to temperatures below 400 °C whereas elemental analyses of the carbon content can be used for wood exposed to temperatures up to a maximum of 650 °C.  相似文献

The plea rolls of the Exchequer of the Jews represent the single most important source for understanding the interrelations and interactions of Jewish and Christian women in thirteenth-century England. A uniquely voluminous series of documents pertaining to the bureaucracy that grew up around Jewish lending after 1190, the rolls reveal the many ways in which women of different faiths were brought into contact — both amicable and oppositional — through financial transactions, predominantly the borrowing and lending of money. It further considers the shared family interests, credit networks and daily necessities that such transactions signified. Finally, by examining specific cases — from large scale, national disputes played out in the Exchequer Court to small-scale disagreements in the locality — it seeks to demonstrate how Jewish and Christian women negotiated with one another for economic resources. It concludes that money-lending, complicated by the particularities of kinship and business structures, first brought women of different faiths together and then tore them apart.  相似文献

Satala is one of the last great military centers in the Roman East available for archaeological and historical investigations. This archaeological site is situated on the crossing of two singularly important routes in North-East Asia Minor. Only little archaeological fieldwork in and around Satala has so far been carried out, thus delimiting our knowledge of the site and its role within the Roman military structure of the East. In order to provide further data on the site, we carried out geophysical surveys including the application of magnetic and electrical resistivity techniques in an area north of the Sadak village. The geophysical surveys within this area (supposedly part of the Roman military camp) proceeded in two stages. The first stage saw magnetic gradiometer imaging studies being carried out on 2.1 ha, measured by a Geoscan FM-36 fluxgate gradiometer by using 0.5 × 1 m grid intervals. For the second stage a different geophysical technique was used—resistivity tomography. Resistivity data were collected using a number of combined 2D resistivity pseudosections in the eastern part of the area which contained very regular magnetic anomalies. The 3D data were obtained by the combination of all survey lines collected from 2D data sets, and thereafter the arranged data were processed by using the 3D robust inversion modified from the smoothness-constrained algorithm. Electrical resistivity tomography investigations revealed that the buried archaeological structures might be located near the surface, except for some structures found in the middle of the studied area. The archaeological structures were furthermore determined by realistic model sections and volumetric representations. Magnetic imaging and electrical resistivity tomography surveys show that the combined usage of these techniques advances the understanding of archaeological structures beneath the surface.  相似文献

Abstract

A group of Māori textile artefacts were discovered in a rock shelter in the southern South Island of New Zealand in 1895. The assemblage comprised a significant number of textile and textile-related artefacts including large and small bags, footwear and prepared leaf and fibre for textile production. The artefacts were privately owned until the 1920s when they were acquired by the Otago Museum, remaining there until new techniques made further investigation possible. This paper presents information from an interdisciplinary investigation of the Puketoi Station assemblage of textile artefacts, which examined artefact structure, form and function, and materials of construction. Interpretation of these artefacts using contemporary textile analysis methods, traditional weaving knowledge, and recent archaeological research, turns them from static objects into dynamic components of culture. The Puketoi Station artefacts embody and illustrate a unique material culture associated with the late prehistoric southern New Zealand Māori lifestyle.  相似文献

The Sepik coast of northern Papua New Guinea is one of the most linguistically diverse places on earth despite communities there currently being connected into wide-reaching social and economic networks that cross language boundaries. One possible explanation for observed human diversity is that social connections were substantially less intensive prior to colonial pacification. As a proxy for human interaction, we compositionally analyzed 287 ceramic sherds from archaeological contexts using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to determine their place of production. Our results indicate that ceramics produced on Tumleo Island—currently the most important regional ceramic producer—were transported to other places on the Sepik coast after ∼1000 BP, suggesting that linguistic diversity on the coast has been maintained in an interactive environment for at least a millennium.  相似文献

During Brazil's 2014 World Cup finals, Argentine fans popularized a chant that stated “Brazil, tell me how it feels”. The chant became viral, and produced a Brazilian response, “Argentina, me diz que se sente”: both discussed relationship of rivalry by joking at the other's expenses. But it was surprising that the chant was based on the melody of a very old song from the American rock band Creedence Clearwater Revival, recorded in 1969, possibly before the birth of those who sang the melody in Brazil (“Bad Moon Rising”, a very popular song recorded many times). This paper discusses several topics derived from that fact: the relationship between popular music and football chants; the uses of popular music and global pop at the World Cups from 1962 to our days; the self-presentation of the “local” (national) fans before a globalized media scene; and, last but not least, the role of sport icons and heroes for the fans but also for the construction of national epics (the icons and heroes invoked in the chants included, obviously, both Maradona and Messi, two of the most important football heroes from the ‘80s until today). The core idea is to show how contemporary football culture must be described and interpreted in the continuous intersection of local texts -and fans’ practices- and global events.  相似文献
