Three‐dimensional (3D) imaging is now extensively used for studying ancient human and animal bones. This method has been consensually adopted by palaeoanthropologists, but its interest in palaeopathology has been challenged. The aim of this paper is to illustrate the contribution of 3D reconstructions to retrospective diagnosis in palaeopathology. We selected six palaeopathological cases among our research corpus representing three nosographic categories (trauma, infection and neoplasia) from various periods ranging from the Middle Palaeolithic to the beginning of the Modern Era. For each case, we compared the diagnostic value of plain X‐ray, computed tomography (CT) slices, and 3D reconstructions. The latter were performed using TIVMI program, a free software for research use developed by one of us. Reconstructions are obtained by surface extraction that follows a segmentation process. We showed that this 3D method allowed reconstructing/quantifying pathological processes on ancient bones, usefully supplementing conventional radiological analyses and clearly bringing an added value to retrospective diagnosis in palaeopathology. 相似文献

The 15th‐century IJsselcog was lifted in 2016 from the river IJssel near Kampen (the Netherlands). From stern to bow and from starboard to portside about 70% of the original wooden hull is preserved. The combined approach of analogue documentation and photogrammetry enabled the research team to reconstruct the original ship in 2D and 3D, followed by a comprehensive study of its nautical characteristics. The hull volume and height were maximized by the shipbuilders using previously unknown construction elements in cogs, such as wales and vertical riders; shipbuilding traits that are generally applied to 16th‐ and 17th‐century carvel‐built cargo ships. 相似文献

ABSTRACTThis paper engages with repeated calls within archaeology for a re-envisioning of the excavation report, contextualized by the transformation of scholarly communication taking place across the humanities and social sciences. This widespread transformation is rooted in a growing interest in showing data together with synthesis and argument, the importance afforded to public engagement, and the proliferation of digital platforms that enable creative presentations of scholarly work. In this context, we discuss our experience producing an excavation report that attempts to integrate several forms of scholarly and public-facing communication on a digital platform, and aims to engage audiences at multiple levels, while simultaneously facilitating data reuse and laying out the authors’ current interpretations. We consider the benefits and challenges of producing work in this way through the example of producing the Gabii Project’s first volume, A Mid-Republican House from Gabii, developed through a collaboration between the Gabii Project team and the University of Michigan Press. This experience is contextualized within the broader discourse surrounding changing expectations about open access, authorship and credit, and sustainability of digital scholarship in academic publishing. 相似文献

Remarkably little is known about the earliest surviving separate-sheet medieval map of Britain that takes its name from its former owner, Richard Gough (1735–1809), and that has been variously dated to between 1300 and 1400, and later. It presents a sophisticated cartographical image at a time when detailed maps of individual regions were almost unknown in Europe, yet nothing is agreed about its possible origins, context (ecclesiastical or secular), or why and how it was compiled. In the belief that historical interpretation has to stem from an intimate knowledge of the map as artefact—the state of the parchment, nature of the inks, palaeography—as well as image, an informal study group of historians and scientists (the Gough Map Panel) was convened in 2012 to examine the map through high resolution digital reproduction, hyperspectral analysis, three-dimensional analysis and Raman pigment analysis. Although the study is still ongoing, much that is new has been discovered, notably about the way features were marked on the map, Gough’s application to the map of a damaging reagent to render place-names readable, and the extent to which the original map (now dated to c.1400), although never completed, was nonetheless reworked on two different occasions in the fifteenth century, effectively creating two further maps. These and other findings are summarized here to encourage the further study of the map’s features that is needed before it can be fully understood. 相似文献

The results of geophysical survey carried out at the archaeological site of Tindari, located 70 km west-north-west of Messina (Sicily, Italy), are presented and discussed. The site is one of the most important archaeological sites, about 90 ha large, on the north-eastern side of Sicily and it was one of the last Greek settlements in Sicily. Keeping in mind the vastness of the site, according to the archaeologists an area, of about 1200 m2 was selected, for a geophysical survey. Electrical resistivity tomography (ERT), including induced polarization (IP) measurements, and seismic refraction tomography were applied in the course of geophysical exploration in the area. The objective of this preliminary geophysical investigation was to verify the effectiveness of the technique for a spatial definition of the buried archaeological structures (mostly walls, columns, etc.) to determine their characteristics and to study the presence of collapsed columns within the zone of archaeological interest, in view of their application in the rest of the site, that, for obvious reasons, could not be entirely excavated in brief times. The geophysical data, visualized in 3D space, revealed a distribution of low-contrast shallow anomalies that indicate the presence of different types of buried structures in the surveyed area. Also, the probable accumulations of collapsed columns could be determined. These results confirm the hypothesis of a large northern extension of the archaeological site and provide useful information to design a more efficient excavation plan. 相似文献

A geophysical survey was carried out at the ruins of Occhiolà Castle (Sicily, Italy), a medieval village located at the north-western part of a hill named “Terravecchia” at 491 m asl. In order to map the archaeological structures (such as walls and burrows), Electrical resistivity tomography (ERT) and seismic-refraction tomography methods were used. The resistivity variations are known to correlate quite well with the lithology, thus providing important information for identifying the buried archaeological remains. On the other hand, seismic velocity variations provide information about the geometrical features of the remains. The two geophysical methods are used in an enjoined way to better aid the interpretation and evaluate the significance and reliability of the results obtained with each single method. The electrical and seismic data are displayed in three dimensions by using the iso-resistivity and iso-velocity surfaces, respectively. This allows us to effectively define the location of the anomalies present in the single electrical and seismic sections. The results obtained in the survey highlight the presence of structures of regular shape, probably due to features of archaeological interest. 相似文献

In the present study a simple method is described for obtaining 3D digital models of petroglyphs of different sizes and characteristics and its usefulness, in the study of this cultural heritage, is evaluated. For this research we used low-cost photogrammetric software and consumer-grade digital cameras, without any other surveying techniques. In order to test this methodology, three field research studies were carried out in Galicia (Spain). 相似文献

This study seeks to add to the burgeoning literature on the relations between nationalism and environmentalism by examining the ideas of A. D. Gordon (1856–1922). Gordon is not well-known outside the realm of Zionist scholarship. Nonetheless, a close re-examination of his ideas reveals that Gordon offers a hybrid brand of deep eco-national theory that frames traditional deep ecological themes within a general theory of nationalism. Whereas Gordon's theory introduces the ‘nation’ as a central notion to deep ecology thought, at the same time, it adds an ecological dimension rarely taken into account in theories of nationalism. This analysis further shows that although Gordon's pioneering eco-national theory had high potential for bridging between the two disciplines, it eventually faded into obscurity like eco-national ideas elsewhere. As Jewish national independence came into view, Gordon's distinctive eco-nationalism was overshadowed by anthropocentric-based Zionist politics. 相似文献
