A painted monolith, as important as the Aztec Calendar or the Coyolxauhqui, has been discovered in the ritual Aztec center of Mexico City. It represents Tlaltecuhtli, the bisexual manifestation of the Earth from whom all life comes. Still, pigments, which have lost their conglomerating resins, have to be retained. In this study, the consolidation of ochre pigment on original fragments from the Aztec sculpture is presented. Several compounds were tested as consolidants, on the one hand natural polysaccharides, Funori and Slobber of Nopal exudate, on the other derivatives of cellulose, Methocel® and Klucel®, and also commercial consolidants as KSE 300® and Paraloid B72®. To simulate the ageing of consolidated samples, they were treated in an Accelerated Weathering Tester. Then, both sets of samples, fresh and aged, were characterized structural, morphological and texturally by using X-ray diffraction, electronic microscopy and nitrogen adsorption, respectively. A leaching test was performed on consolidated samples to evaluate the consolidant efficiency.  相似文献

To date, limited numbers of dental calculus samples have been analyzed by researchers in diverse parts of the world. The combined analyses of these have provided some general guidelines for the analysis of calculus that is non-destructive to archaeological teeth. There is still a need for a quantitative study of large numbers of calculus samples to establish protocols, assess the level of contamination, evaluate the quantity of microfossils in dental calculus, and to compare analysis results with the literature concerning the biology of calculus formation. We analyzed dental calculus from 53 teeth from four Brazilian sambaquis. Sambaquis are the shell-mounds that were established prehistorically along the Brazilian coast. The analysis of sambaqui dental calculi shows that there are relatively high concentrations of microfossils (phytoliths and starch), mineral fragments, and charcoal in dental calculus. Mineral fragments and charcoal are possibly contaminants. The largest dental calculi have the lowest concentrations of microfossils. Biologically, this is explained by individual variation in calculus formation between people. Importantly, starch is ubiquitous in dental calculus. The starch and phytoliths show that certainly Dioscorea (yam) and Araucaria angustifolia (Paraná pine) were eaten by sambaqui people. Araceae (arum family), Ipomoea batatas (sweet potato) and Zea mays (maize) were probably in their diet.  相似文献

The origin of Romita pottery has been a controversial topic during the last three decades of Colonial Mexico archaeological studies. Lead isotopic analyses of glaze coatings of Spanish and Mexican pottery, and Romita ceramics unearthed from the archaeological site of the Metropolitan Cathedral in Mexico City provide evidence that support a Mexican origin.  相似文献

Using instrumental neutron activation analysis (INAA) of prehistoric pottery, daub, and modern clay samples from Valencia, Spain, we tested expectations on changes in raw material use with socio-economic shifts during the Neolithic (ca. 5600–2800 BC). Elemental analysis identified three distinctive clay source groups used by Neolithic potters. Contrary to expectations, a shift in raw material use was identified between the Early and Middle Neolithic despite general similarities in technological practices. In the Late Neolithic, pottery production became more specialized, but potters used the same range of clay sources documented earlier. This study illustrates the utility of INAA for testing hypotheses of prehistoric craft production.  相似文献

This article analyses the Women's International League for Peace and Freedom's (WILPF) and Women's International Democratic Federation's (WIDF) fact-finding missions sent to Chile in 1974. It explains how women's international organisations presented reports and information about human rights abuses during Genera Augusto Pinochet's dictatorship (1973–1990). By using their publications, oral interviews, memoirs and press reports, the study sheds light on the extensive efforts deployed by the WILPF and WIDF to disseminate knowledge and promote actions designed to improve the lives of Chilean women. The article shows that women's international organisations promoted inclusive ideas of rights, including women's particular experiences under military rule, and that such efforts built in the organisations' previous experiences of human rights activism.  相似文献

The first attempts to identify amorphous organic substances in archaeology date to the end of the 19th century and the beginning of the 20th century. The 1960s saw the development of infrared spectrometry, and then separative and mass spectrometry analyses were implemented in the 1980s. But it is only since the 1990s that extended and systematic research programmes were devoted to these substances. The number of publications has not stopped growing and is becoming exponential. To get an overview of the lipid studies in archaeology, we conceived the ARchaeological Organic residues Literature Database (AROLD) as a first structured and collaborative research tool. This paper describes the challenges of setting up such a database, details its architecture, presents the choices involved in its implementation, and discusses the possibilities of sharing and evolving this tool.  相似文献

Extant research has analysed the impact of security policies, truces and informal agreements on both the dynamics and traits of organized violence in El Salvador. However, less is understood about variation in the levels of lethal violence across subnational units. This article contributes to filling this gap. Based on a case study of the municipality of Chalatenango, the analysis shows that community organization and translocal dynamics are crucial to explaining violence containment. Local communities have managed to control the levels of lethal violence and deter criminal actors amid a national context characterized by state neglect and chronic violence. Community organization is not territorially bound but extends across transnational networks. Migrants are a source of livelihoods for the local population; they also contribute to providing public goods and participate in local forms of organization. Transnational networks have forged a migration corridor that enables immigration to the United States. In addition, community organization informally contributes to the capacity of the local state to perform its functions, thereby shaping cooperative state–society relations. This analysis sheds new light on the conditions shaping the variation in levels of violence at the subnational level and local governance dynamics.  相似文献

This article reflects on Hayden White's understanding of the subject and explores how best to move forward discussions in theory of history after his arguments about narrativity. To do so, I reconsider his arguments in light of more recent feminist and queer theorizations. Through a reconstruction of the current international new wave of feminism and LGBTQ+ activism as a rich and complex social movement that involves a narration of its own (practical) past, I will recontextualize and revaluate White's insight from the perspective of Judith Butler's theory of subject formation. The argument will unfold in four parts. First, I will recall White's ironic and existential stance on language and narrativity in the representation of reality and in relation to social beliefs. Second, I will again raise the question of the value of narrativity, as framed by White, in the context of the publication of a recent feminist manifesto. It is here that another issue will emerge as crucial: the relationship between the limits of linguistic self-consciousness and the question of the subject. In the third part, my argument will take a partial turn “against White” and toward Butler's subject formation theory. My claim will be that there is a residue of the belief in the sovereign individual in White's insistence on self-consciousness. However, I will also show that his suspicion regarding the psychological impulse toward narrative closure can be re-elaborated as the challenge Butler is facing with their theory of subject formation: that of critically resisting the belief in our being coherent and self-sufficient individuals. In the fourth part, I will present Butler's refiguration of the thesis of the subject's opacity in terms of the primary relationality that binds human beings to one another, and I will offer a new understanding of the individual, norms, agency, infancy, and ethics. Finally, I will conclude that we are bodies in history and that theory of history can find a promising line of research through this conception of the subject, a conception that reframes how we understand the intimate links between political consciousness, historicity, and embodiment. I also claim that this line of research constitutes an ethics for our historical undoing.  相似文献
