Identification of the volcanic material (pozzolan) stored in a Roman ship of the fourth to third century bce , wrecked in the ancient harbour of Pisa (central Italy), was based on ratios of selected trace elements. The compositions of the major volcanic products erupted by the volcanoes of the Roman province, including the volcanic districts of Latium (Vulsini, Vico, Monti Sabatini and the Alban Hills) and Campania (Roccamonfina, the Phlegraean Fields, Ischia, Procida and Vesuvius) are compared with the pozzolan from the Pisa ship. Superposition of the Zr/Y, Nb/Y and Nb/Zr ratios of the pyroclastic material from the wrecked ship (computed from the published literature) allows correlation with the products of the Onano eruption from the Vulsini Volcanic District. The Vulsini rocks outcrop extensively in a sector drained by the hydrographic network of the Fiora River, which has been a well‐developed commercial water trade route since Etruscan times, with a river port and a sea port connected to the important town of Vulci, and, since 273 bce , part of the larger Roman harbour system of Cosa.  相似文献

Addressing the recent call to rethink history as a form of presence, the essay works toward a recovery of a space in which such presence of history is encoded. I argue that history as a form of active perception is akin to virtual witnessing of the past in the moment of our encounter with historical artifacts, be they texts, photographs, or buildings. To this end, I engage with the conceptual and material aspects of historical perception, deriving a model of history as “inhabited ruins,” the way it emerges together with historical consciousness and finds an especially dynamic expression in Georg Simmel's philosophy of culture. Throughout, I work with the notion of distance and trans‐dimensional presence as the forces that shape and reshape historical awareness. Ruins, intimately connected to the modern historical imagination, are approached not as sites of commemoration or nostalgia, but as spaces of active exchange between presence and disappearance. As such, they are taken to be the models for the transitive character of history itself, blurring the division between perception and thought. In other words, ruins are taken as structures that evoke and summon the past to an encounter with contemporary reality—a type of co‐appearance that opens the possibility of virtually witnessing the past. I conclude that the logic of “inhabited ruins” constitutes the event‐horizon of modern identity, always placing history right at the threshold of fragmentation.  相似文献

In 1503, the canons of Ripon Minster initiated a building campaign to replace the church’s nave. Through a careful study of the documentary evidence, including sources that have not previously been considered, this article investigates how Ripon’s clergy organised and funded the project. It offers a more precise chronology of the works and an assessment of their impact on the use of the church by its parishioners. The article also considers the clergy’s motives for rebuilding, proving that the renovation was not a reaction to the old nave’s deterioration so much as an initiative to create a grander architectural setting for processions and more space for burial within the church.  相似文献

The ruins of an ancient Greek temple on a Cycladic island form part of an Orthodox Christian shrine. To local people and returning migrants, the site is that of their patron saint; its pre‐Christian past is irrelevant except in so far as it establishes their specific link with the ancient world, and thus with national claims of unbroken continuity between modern and ancient Greece. To early travellers and antiquarians, and to today’s archaeologists, it has been primarily the ancient site which is of interest, while tourists are more concerned in finding “an unspoilt island”. A historical survey of information about the ancient and the Christian site reveals ambiguities and confusions about both. These multiple meanings for locals and scholars are discussed.  相似文献

In the present work we attempt to recover endogenous ancient DNA from cereal grains preserved under different conditions: charred, partially charred and waterlogged. A total of 126 grains from naked wheat and 18 from barley from different sites on the Eastern Iberian Peninsula ranging from the beginning of agriculture in the region to the turn of the Common Era, were studied. Two different extraction protocols were used, a standard phenol–chloroform method and a silica-based DNA extraction procedure implemented for artificially charred seeds. Amplifications were directed to three markers: the large subunit of ribulose 1,5 biphosphate carboxylase (rbcL) and the microsatellite WCT12 in the chloroplast genome and the x and y subunits of the high molecular weight glutenin gene (Glu-1) in the nucleus. The first two were used to assess the preservation status of the samples, while with the third we tried to identify the wheat grains at species level. It was possible to obtain eleven positive amplifications in 8 partially charred seeds but only two amplifications of the Glu-1 gene from a single sample of the Early Bronze age were genome-specific. Different contamination sources were identified and reported. Cloning and alignment of sequenced clones showed a correspondence of the amplified fragment to modern wheat D genome haplotypes. This result suggests that the sample corresponds to hexaploid wheat (Triticum aestivum L.), thus being the first ancient DNA evidence to date for the cultivation of hexaploid wheat in the prehistoric agriculture of the Iberian Peninsula. Moreover, obtained results highlight contamination problems associated to the study of ancient archaeobotanical charred seeds suggest that the combination of a silica-based extraction method together with the amplification of specific targets is a good strategy for recovering endogenous ancient DNA from this kind of material.  相似文献

Radial systems of spoke-like pathways, often termed “hollow ways,” are frequently found surrounding mounded tell sites in northern Mesopotamia and have been explained as the product of a particular set of land use practices involving dry-farming agriculture and intensive ovicaprid pastoralism. Yet while similar subsistence strategies were very common across the Near East throughout much of the Holocene, classic hollow ways have only been previously documented in a small region and articulate almost exclusively with sites of the third millennium BC. This paper presents newly discovered hollow ways in western Syria and southwestern Iran, made possible through analysis of an online database of declassified, Cold War-era CORONA satellite imagery. The association of these previously undocumented ancient roads with archaeological sites dating to the Iron Age, Roman/late Roman and early medieval periods, suggests that the land use practices which produced radial route systems may have been quite widespread. Taking into account the wide geographic and temporal distribution of hollow ways, analysis explores various aspects of the agro-pastoral systems that disparate communities may have shared. Results confirm some aspects existing models of hollow way formation, while offering some refinements in terms of the roles that settlement organization, agricultural land use and pastoral strategies play.  相似文献

Archaeological studies including stable carbon and nitrogen isotope analyses of bone collagen from human remains have suggested their heavy dependence on terrestrial foods during the Jomon period in the inland central region in Japan. However, it is not easy to quantitatively evaluate the extent of carnivory for archaeological human remains based on the bulk collagen chemistry, because of variable 15N-enrichment factor along the trophic step and background isotopic variations in ecosystems. In order to overcome these problems and more precisely evaluate diets of prehistoric humans who strongly adapted to terrestrial environment, in this study we applied nitrogen isotope analysis of individual amino acids in bone collagen to two inland human populations in the Jomon period. Our results suggest that the two populations were predominantly dependent on the C3-plant-based terrestrial ecosystem and consumed little aquatic resources. Furthermore, their mean trophic positions (2.7 for both cases) are closer to that of the fox (2.8–3.0) rather than those of pure herbivores (2.0–2.2), and show little change over time. These results are the first evidence that inland Jomon populations may have had more carnivorous diets than is traditionally considered.  相似文献

Recent lidar and pedestrian surface surveys have remapped the well-known Mesoamerican site of Izapa and the surrounding Soconusco piedmont. These data document: 1) occupation from the surrounding piedmont environment, 2) significantly larger estimates of the site's size during both the Formative and Classic periods as well as 3) new architectural features from the monumental site core. Methodological issues are outlined for combining high precision lidar mapping with ground truthing and pedestrian survey that focuses on surface collection of temporally diagnostic artifacts. Results are presented for 670 mounds documented in an area of 43.1 sq km in and around the ancient capital of Izapa.  相似文献
