The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.  相似文献

We use trace element discrimination diagrams to provide a geochemical fingerprint for Tufo Lionato, the volcanic rock most commonly used in the ancient Roman dimension stone technique. Based on the comparison of their geochemical signatures, we identify different rock facies of Tufo Lionato employed since the fourth to third centuries and through the second century bce in the construction of the temples of the Area Sacra di Largo Argentina. These rock facies correspond to two previously identified building stones: Aniene Tuff and Monteverde Tuff, named after their supposed source areas located in the Aniene River Valley and in the homonymous locality of the Tiber River Valley, respectively. However, the results of our study demonstrate previous misidentification of these volcanic rocks in the different construction phases of Temple C, providing a revision of the dating system currently accepted for the diffusion of Tufo Lionato architecture. We show that the Aniene facies has been exploited since the end of the fourth century bce and that it was employed along with Tufo Giallo della Via Tiberina in the podium and staircase of Temple C, whereas observations at Largo Argentina suggest that the ‘Monteverde Tuff’ was only sporadically used in the early phases of the dimension stone construction technique.  相似文献

A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases.  相似文献

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies.  相似文献

The last time texts were brought onto the general theoretical and methodological agenda of the human and social sciences, they were reintroduced into history in terms of an indefinite set of indefinitely complex contexts, which gave every text a specific date and location in a network of other texts and events. A couple of decades later, however, a more prominent feature of texts seems to be that they are permanently on the move: they circulate, have effects on other things, change and transform realities, and are at the same time themselves translated and modified. In the literature exploring the textuality of history, these dimensions have been under‐theorized and often ignored. To meet this challenge, we need to develop concepts and approaches that enable us to place the mobility of texts as well as their mobilizing force at the center of our current historical concerns. In this article we will explore what the consequences of this move could be, and what resources are already at hand in different scholarly traditions. Exploring the entanglements between actor‐network theory (ANT in the version of Bruno Latour), on the one hand, and literary criticism, linguistics, and book history, on the other, enables us to focus on how texts move and how they move others. We will proceed in this essay by identifying three decisive moments in twentieth‐ and twenty‐first‐century textual scholarship, often conceptualized as “turns,” which are linked to the works of three path‐breaking authors and which at the same time represent three different stages or forms of textuality: the linguistic turn (Saussure), the turn to writing (Derrida), and the turn to print (Eisenstein). Our discussions of these three moments and forms of textuality aim at uncovering how they also represent seminal moments in Bruno Latour's development of the theoretical and methodological complex now referred to as ANT.  相似文献

This study aims to analyse the problem of Vico’s religiosity, still a subject for debate, in the European tradition of universal historiography. Vico’s historical reconstruction has traditionally been considered as orthodox and apologetic. The Neapolitan philosopher, in his major work, New Science, tried to defend not only the historical veracity and authority of biblical narratives as the only source to reconstruct the initial phases of history, but also the temporal and spatial frame of historia salutis, confuting the thesis of a greater antiquity of pagan nations. Nonetheless, it is difficult to conclude that Vico’s historical reconstruction followed the same route of the apologists of his time. Vico demolished not the temporal and spatial sphere, but the unitary frame of historia salutis. In Vico’s setting, all nations formed their civilizations in an autochthonous way and developed them autonomously with diverse timetables. Vico introduced the concept of the plurality of history. In this way, the Neapolitan philosopher contributed to the process of secularization of universal history in a completely different way from his contemporaries.  相似文献

This article offers a re-contextualization of the Positivism Dispute between the Frankfurt School and advocates of empirical sociology in the German sociological profession between 1954 and 1970. Investigating the reasons why the German Sociological Association convened in Tübingen in October 1961, it assigns a more peripheral role to Karl Popper and this now famous seminar. Focusing instead on the debate among German sociologists from the mid-1950s which prompted the convention of the seminar and the invitation for Popper to speak, the article maintains that philosophy of history was the central concern of the Positivism Dispute. In this debate, members of the Frankfurt School emphasized contingency in history and society, while sociologists such as René König, Helmut Schelsky, Ralf Dahrendorf, and Arnold Gehlen advocated sociology as the empirical study of ‘given’ social facts. By doing so the article questions the narrative of the Positivism Dispute advanced by Karl Popper and some of his followers, as well as interpretations which have focused on debates during the aftermath of the Tübingen seminar in the 1960s.  相似文献

This paper examines the diversity of uses of Adam Smith’s ideas in nineteenth-century American debates about the tariff. Legislative debates about American trade policy ran almost uninterrupted from the 1820s to the end of the century; as a result, they provide an abundance of examples of the ways in which legislators marshaled economic ideas to shape political discourse and influence policy. Smith’s causal ideas about free trade and its effects were referenced in policymaking, and Smith’s intellectual authority was often invoked as a legitimating device for partisan ideology. These uses, I argue, contributed to the sloganizing of Smith as the ‘apostle of free trade’ and his enduring popularity as a political icon in American politics.  相似文献
