In the present study, the fragments of wall painting found in the Roman Temple Complex at Horvat Omrit were analysed for the first time using the non‐destructive techniques of X‐ray diffraction (XRD) and scanning electron microscopy (ESEM) equipped with energy‐dispersive X‐ray spectroscopy (EDS). The application of these methods enabled unambiguous identifications of the pigments and plaster components of the samples. Quantitative information on mineral composition, crystallite size and elemental composition of each studied paint layer and plaster was collected. Based on the results of the XRD and EDS analyses, the green pigment was identified as celadonite. It was revealed that the Egyptian blue pigment does not contain impurities of tin and lead, and this excludes the use of bronze scrap in its synthesis. Comparison of the mineral composition of the paint layers indicates that a wider palette of colours was obtained by mixing the available mineral pigments. The study of cross‐sections of painted specimens revealed the usage of slaked lime for plastering. The obtained results give a new insight into the wall painting technique employed by ancient artists at Horvat Omrit, in northern Israel.  相似文献

Voltammetry of microparticles using a paraffin‐impregnated graphite electrode (VMP/PIGE) was applied as a very local and non‐invasive analytical technique in order to investigate the presence of remains of metallic plating on two ferrous and one cuprous artefact from the medieval period. The analyses have been performed locally and selectively on regions presenting particular features, such as texture, cohesion and colour differences. The results confirm local differences in chemical composition, leading to conclusions about the presence of metallic plating on these artefacts.  相似文献

The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.  相似文献

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world.  相似文献

This paper examines some of the emerging critical civil society debates in relation to the one‐state solution being the most appropriate geo‐political arrangement for the articulation of freedom, justice and equality in Palestine‐Israel. This is done with reference to the Israeli Committee Against House Demolitions’ 2012 statement in support of a bi‐national state and the ensuing critiques it attracted from Palestinian supporters of the one‐state position. Drawing on these debates which have largely revolved around Jewish Israeli rights to political self‐determination in Palestine‐Israel, this paper proposes that alternative versions of self‐determination as cultural rights for the established Hebrew‐speaking national community represent a more inclusive form of self‐determination in the eventuality of decolonisation.  相似文献

It is widely acknowledged in the literature that the study of blame avoidance behavior (BAB) exhibited by public officials is scattered and unconcentrated, and that, for the most part, it neglects both contextual factors and comparative research. These deficits inhibit the production of the kind of generalized findings necessary to better understand potential consequences for the policy process and the workings of political systems. We address these deficits by developing a framework that takes stock of blame avoidance research, clarifies the explanatory potential of contextual factors, and allows for a systematic context‐sensitive cross‐case analysis. For illustrative purposes, the framework is applied to the Home Insulation Program in Australia as a critical case. This case reveals the explanatory potential of contextual factors for the understanding of BAB and the consequences thereof. We conclude by stating the advantages of our framework and explain how it can be used for comparative research.  相似文献

Within Iran, there is little archaeological evidence for relationships between newly arrived Early Trans-Caucasian (ETC) or Kura-Araxes settlers and earlier inhabitants and contact with neighbouring cultures, or for their apparently abrupt end. Based on the evidence, the Iranian Kura-Araxes was not a simple ‘copy' of the Caucasian Kura-Araxes package. Ceramic traditions show local peculiarities, and all are elements suggesting that the Kura-Araxes traditions went through processes of adaptation, change and re-elaboration according to local tastes and technologies. In this study, an archaeometric approach to ceramics in the Kolyaei Plain of central Zagros contributes to the discussion of contact and exchange between indigenous communities and several cultural spheres of influence on the Early Bronze Age (beginning in the fourth millennium bce ). Morphological data, as well as the mineralogical and chemical composition of ceramics, were applied to determine the major and trace elements of the pottery shards. Based on the trace element profiles, it can be suggested that all the pottery shards are in the same group and they strongly are local products. The ceramic provenance indicates the same patterns of material interactions during the ETC or Kura-Araxes in all the sites within the Kolyaei Plain.  相似文献

In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km.  相似文献

This article contributes to the emerging literature on the role of constitutional courts in consociational democracies. While most works have approached the topic from the perspective of regime dynamics, this analysis focuses on how courts relate to the constitutions they are mandated to enforce. Beyond addressing the empirical question of what choices courts make in their balancing between universal values and stability, this article also investigates how courts do this balancing. Through the analysis of seven cases from two consociations, Bosnia and Herzegovina and Northern Ireland, I argue that courts embrace specific interpretive approaches (proportionality analysis, purposive interpretation, and the political question doctrine) to reconcile the ideas of constitutional supremacy and respect for political agreements. The analysis also demonstrates how—by their nature political—framework agreements establishing consociational settlements become primary reference points for interpreting constitutional documents.  相似文献
