This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili.  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

On occasions, archaeologists have to deal with serious difficulties to differentiate between processes that ultimately are responsible for the formation of stratigraphic units.Sometimes we face problems related with depositional units in multilayered deposits and other times, we ask for the character of some dark surface soils, very similar to natural paleosols and usually associated with archaeological findings. In both cases, the problems we must address concern the relative impact of human activities.The imbalance between anthropic and natural processes in the formation of archaeological deposits is crucial for a correct interpretation of the processes involved in the formation of archaeological sites, but also of their occupation-abandonment dynamics and the understanding of their spatial behaviors and relationship with the environment.In this paper we propose a new methodological approach for the identification of anthropogenic fingerprints in stratigraphic units through Rare Earth Elements (REE) soil analysis. The role of REE for the effective identification of sediment provenance due to their coherent behavior during weathering, erosion and fluvial transportation and their high resistance to chemical mobilization is well known in other areas of knowledge. We try to explore its potentiality in a challenging archaeological context. Our purpose was to identify human traces in stratigraphic units where archaeological materials are scarce or absent intertwined with others richer in archaeological remains by the determination of multiple elements and statistical studies. We believe that Rare Earth Elements (REE) soil analysis provides unique insights for a better characterization of natural and archaeological sediments but more importantly to recognize different stages of the gradient. We expect to discern between natural versus anthropic units and between primary versus secondary deposits (redeposition), using the case of the Neolithic site of Mas d'Is (Alicante, Spain) as an example. The application of the Principal Component Analysis (PCA) remarks differences in REE values, those analysis show differences between units of undoubtedly anthropogenic origin and control samples taken from natural sediments –including marls bedrock–, in their vicinity, but also we could notice finer nuances like the degree of human contributions to paleosols formation.  相似文献

A metallurgical study of platinum plating on a gold pendant of the La Tolita culture of northern Ecuador was carried out, using high‐magnification examination by scanning electron microscopy with analytical facilities. The plating layer was found to comprise a 25 µm thick foil of platinum grains sintered with a gold–silver alloy. The high silver content of this alloy suggests the deliberate selection of pale‐coloured, silver‐rich alluvial gold. The foil had been bonded on to the pre‐formed gold sheet by hammering and heating. It is postulated that a strip of gold sheet was plated by this method and that several pendants were cut from it.  相似文献

The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European contexts. The improvements allow: (1) faster analysis of a broad series of artefacts or those with large use‐surface areas likely to retain more pollen; and (2) a more thorough, deeper and precise cleaning method, allowing the study of smoother artefacts. Finally, the recovery of Trifolium‐group pollen from a macro‐lithic tool from Xicotó rock shelter (Montsec ranges, Spain) demonstrates that the pollen washes technique can reveal new insights into both the use and consumption of wild and domestic plants by prehistoric societies, and the functionality of archaeological objects whose interpretation is still problematic.  相似文献
