The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga. 相似文献

The site of Kharaib al-Dasht, located on the northern coast of Failaka, is a late Islamic settlement with an extensive fishing infrastructure. It has been excavated since 2013 by the Kuwaiti-Polish Archaeological Mission. The ceramic assemblage collected so far exceeds 18,000 fragments. The sherds underwent technological and typological analyses, which demonstrated a wide diversity of local common kitchen wares, consistent with the needs of households specialised in fishing. A considerable percentage of imported vessels was brought to Failaka from the Arabian Gulf and Persia, though Far Eastern luxury tableware was also attested. This paper demonstrates the socioeconomic role of Kharaib al-Dasht in the context of trade exchange on the microregional (Kuwait) and macroregional (the Gulf, South and Eastern Asia) scales in the eighteenth and nineteenth centuries. 相似文献

Events such as Brexit and the Gilet Jaunes protests have highlighted the spatial nature of populism. In particular, there has been increasing political divergence between urban and rural areas, with rural areas apparently having lost faith in national governments. We investigate this divergence using data on over 125,000 EU citizens from the European Social Survey from 2008 to 2018. We show that people in rural areas have lower political trust than urban or peri-urban residents, with this difference clear for six different forms of political institutions, including politicians, political parties, and national parliaments. There has been divergence of political trust between urban and rural Europe since 2008, although this is primarily driven by Southern Europe. While these results can partly be explained by demographic differences between cities and the countryside, divergent economic experiences, differences in values, and perceptions that public services are less effective outside of urban areas, there is a residual ‘rural effect’ beyond this. We argue that the polarisation of urban-rural political trust has important implications for the functioning of European democracies. 相似文献

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time. 相似文献

ABSTRACTThis research report aims to give detailed information on the pottery from the 1999 and 2013-16 excavation campaigns taking place at the Tell Sufan site in Nablus, Palestine. These were conducted by the Department of Antiquities at An-Najah National University (ANU) in Nablus. It is of note that this ancient pottery has never previously been the subject of research nor has any literature been published on it. Our methodology consists in: analysing the pottery by identifying it, typifying it, and giving it a function; providing chronological information on the site; comparison of the pottery with that from other sites in Palestine, using archaeological information from the site; and contextualising our findings with other historical and archaeological studies. Examination of the functional use of the pottery allows us to demonstrate human activity at the Tell Sufan site, giving information on the most prosperous phases of occupation in regard to economic aspects, through the late Bronze Age, Iron Age and Byzantine-Early Islamic periods. 相似文献

Preliminary Characterization of Pottery by Cathodoluminescence and SEM–EDX Analyses: An Example from the Yeha Region (Ethiopia) 下载免费PDF全文
Yeha was a political and cultural centre of the Ethio‐Sabaean culture (D’MT) in northern Ethiopia and southern Eritrea. Part of the archaeological research deals with pottery of local, regional and imported origin. The research—investigations and examinations—tries to classify local pottery in two ways: first, by analysing the mineralogy of the temper using light microscopy and cathodoluminescence; and, second, by analysing the main element composition of the clay matrix using a scanning electron microscope with energy‐dispersive X‐ray detection (SEM–EDX). The cathodoluminescence shows that the temper material has differences in the colours of feldspars with a similar mineralogical composition. The results demonstrate that the pottery was produced by using local material that originates from various sources in the Yeha region and that the same raw materials were used in different types of pottery. 相似文献

Northeastern China is one of the centers of early development of agriculture and sedentary life, as well as of the subsequent development of social complexity and distinct cultural attributes. While the outlines of this trajectory are clear, its important details are still elusive. Like all other regions of northern China, there is little data on the all-important transition from nomad hunter-gatherers to sedentary agriculturalists. The Fuxin Regional Survey was designed as the first step in accumulating new data and addressing the geographic and ecological contexts of these socioeconomic processes. Among the most remarkable results of this survey is the identification of early ceramics, which possibly predate the transition to agriculture. The systematic collection and analysis of stone tools was done in a way never before done in this region. Analysis of our findings, using GIS and other methods, sheds new light on the local trajectory of human adaptation in this area. 相似文献

Ancient iron tie-rods are handcrafted elements with large geometric irregularities, due to production techniques (they are shaped by hammering and linked by hot-forging) and corrosion processes. In common practice, their cross section (that is one of the main parameter to assess their strength) is manually measured on site with a manual caliber. By analyzing a set of detailed three-dimensional (3D) digital surveys of real ancient tie-rods, this study provide an evaluation of the errors made by in-situ manual geometric measurements. In particular, it shows that, in some cases, manual on-site survey is sufficiently reliable and has errors that fall below 10%. Moreover, it shows that when tie-rods have high corrosion levels in hidden zones (typically those close or within the retaining walls) the on-site survey of visible parts only may produce far greater errors that exceed 100%, leading to a strong overestimation of the cross-section of the tie. The ongoing study is a first step toward the definition of correction coefficients to be applied to the on-site manual measurements of ancient tie-rods, with the final aim to improve the reliability of structural analyses. 相似文献

This paper evaluates chronological trends in the presence and absence of domestic animal bone (sheep, goat, and cattle) and pottery in Namaqualand, the proposed gateway to the rest of South Africa for early herders or hunter-gatherers with sheep and ceramics. We update date calibrations with local ΔR corrections and mixtures of recent calibration curves and include five previously unpublished dates. We use histograms of calibrated medians, sorted in 100-year bins, to assess sustained regional patterns with dates associated with domestic animal bone and pottery (n = 73). While too small to be useful as a population proxy, the current set of dates does reveal three pulses of occupation separated by two clear gaps, which we evaluate with a Bayesian model of three sequential phases. The model's boundaries are used as estimates of the dates of Early (AD 80–210), Middle (AD 490–790), and Late (AD 1180–1690) occupational phases separated by two substantial lapses of 280 and 380 years, respectively. The alternating phases of presence and absence are suggestively correlated with climate shifts, leading to a discussion of the idea that effective moisture was a crucial factor in choosing whether to occupy Namaqualand. The set of archaeological dates has greater temporal and spatial resolution than many regional climate data, so we suggest that these trends may more accurately reflect the variable conditions specific to Namaqualand, at least until they are refined by future climate research. 相似文献
