Ochres were the most common source materials for pigments used in Palaeolithic rock art paintings. This work analyses the petrographic and geochemical signatures of different ochre samples from outcrops inside Tito Bustillo Cave and the Monte Castillo Caves using the most common techniques (petrography, XRD, SEM–EDS and ICP–MS) in archaeological pigment characterization studies. The results obtained permit the identification and characterization of the different source ochre types and, furthermore, allow the establishment of mineralogical and geochemical proxies for the study of questions related to ochre characterization, formation processes and provenance.  相似文献

In 1935, as Europe witnessed the rise of fascism, Paul Valéry tried to identify the origins of the crisis in a lecture titled “Le bilan de l'intelligence.” Things were better, he claimed, when people were able to understand their present moment as the result of past events—that is, when “continuity reigned in the minds.” In this article, I discuss why that sense of continuity with the past is, in fact, indispensable for individuals and societies alike; using instances from great works of fiction, ranging from Don Quixote to the novels of Toni Morrison and Abdulrazak Gurnah, I suggest that fiction—the literary imagination of the historical past—might be uniquely adept at restoring continuity when it is broken.  相似文献

Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated? Can cut marks made with different types of the same raw material type be characterized and differentiated? The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra‐sample and inter‐sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts.  相似文献

Historians have often considered the international veterans’ organizations which came into being after World War I as proof of the pacifist, internationalist orientation of the majority of the Great War ex-combatants. However, veterans active in these organizations were often inspired by specifically national and partisan objectives that belie any simplistic equation between altruistic transnational activism, international cooperation and pacifism. Conceiving of war veterans as transnational actors, this article explores the origins and decline of the veterans’ transnational sphere in the interwar period. It singles out four shades of competing veterans’ internationalism and describes the crucial differences that separated actors such as Henri Barbusse, René Cassin, Henri Pichot and Carlo Delcroix, among others. The article argues that both the veterans’ organizations and their protagonists, while reaching out across national borders, remained embedded in specific constellations of personal trajectories, political partisanship, nation-state interests and inter-state alliances. Their political and social activities also tried to reshape, and were subjected to, existing or emerging spatial configurations such as Great Power alliances and wider internationalist projects. Thus, the article shows that there was no homogeneous transnational sphere in international veteran politics; it was rather the competition between different internationalist practices and projects which shaped veterans’ transnational activities.  相似文献

This study aims to simulate the long-term deterioration of architectural glazes exposed to open air in a highly polluted urban environment. A laboratory experiment—a 14-day long accelerated weathering test—on glazed roof tiles has been performed to reveal the damaging influence of contacting acid solutions originating from dissolved gaseous pollutants, mainly SO2. The studied tiles are made by the Hungarian Zsolnay factory and applied on two buildings in Budapest in the 19th and 20th century. The ceramics were covered mainly by lead glazes in the construction and lead-bearing alkali glazes in the renovation periods.

The solution of pH2 induced a greater dissolution, especially of alkali and alkaline earth metals (up to 2886 ppm), but less lead (up to 21 ppm) from the lead glazes of the construction periods. Newly formed lead sulphate (anglesite) on the corroded glaze parts precipitated on some lead-bearing alkali glazes, with moderate dissolution of alkali and alkaline earth metals (up to 396 ppm) accompanied by higher amount of lead (28–39 ppm). Based on the results, the main determining factor in the durability of glazes is mostly their chemical composition and less their preliminary degradation state.  相似文献

Quartzite was the second most‐often used lithic raw material in Europe in the Palaeolithic. However, this rock has not been characterized fully from the geo‐archaeological point of view. This study characterizes, defines and determines types of quartzite in northern Spain through a methodology that integrates petrography, digital image processing and X‐ray fluorescence. As a methodological foundation for the characterization of the material, it aims to open the possibility of discovering mechanisms of mobility, selection and management of quartzite by prehistoric societies. The types determined, based on the petrogenesis of the material, enable a better understanding of the archaeological sites of El Arteu and El Habario in the context of northern Spain in the Middle Palaeolithic.  相似文献

Studies on the mobility of past populations are useful in the interpretation of trade and lifestyle. Preservation of ancient paths is uncommon. In Tenerife, a volcanic island of the Canary Archipelago, ancient paths are still preserved, due to the dry climatic conditions and the presence of extensive lava fields in inhospitable areas of the Island. The Guanches who inhabited this island before the Spanish conquest, those surviving in the highlands after the conquest, and modern goatherders, utilised a still identifiable net of paths to access the central mountains. Clasts in the beds of these paths have suffered variable abrasion, depending on the time during which the path was used and on the number of people and/or animals that have walked on it. We estimated roundness of 1819 clasts collected at different parts of the net of paths crossing different lava fields of known antiquity. Significant differences in roundness of clasts among different parts of the paths allowed an inference about the relative importance of each of the paths constituting the net. Therefore, assessment of roundness of the clasts of the beds of paths may aid in the understanding of the migrations of people.  相似文献

ABSTRACT. In this study the authors analyse Czech national identity after the break‐up of Czechoslovakia and before accession to the European Union. National identity is understood here as a construct consisting of several elements, four of which the authors analyse: territorial identity (localism, regionalism, patriotism, and Europeanism), the image of the nation – the cultural nation (ethno‐nation) and the political nation (state‐nation), national pride (in general, and in cultural performance and in the performance of the state), and love for the nation – nationalism (or more precisely, chauvinism) and patriotism. To create a more complex picture of Czech national identity the authors compare it with national identities in eleven other European countries. To conclude, the authors analyse the attitudes of Czechs toward the European Union, and national identity is used as an important explanatory element of the support for EU governance.  相似文献
