Multispectral documentation and image processing analysis of the papyrus of tomb II at Daphne,Greece

This paper refers to the study of an ancient papyrus, dated ca. 420/430 BC, found in 1981 during an excavation at Daphne, Athens, Greece, using multispectral imaging combined with image processing analysis. It was assumed that the papyrus contained ancient Greek musical notation but the condition of the object hindered the drawing of any conclusion based only on visual examination. This fact, combined with the significance of the object itself, as it is the oldest papyrus which carries Greek text, pointed to the application of non-invasive techniques to enhance its readability. The multispectral imaging carried out in the range of 420–1000 nm enabled the detection of more letters on surface layers, at various places and orientations. False colour imaging proved to yield better results in distinguishing the letters compared to single wavelength recording. In some cases, letters from several layers underneath are revealed in the infrared. The letters present different greylevels according to the layer they belong. An interesting result coming from a simple subtraction of the infrared image at 1000 nm from the visible one at 660 nm is that different layers of the papyrus can be distinguished. The Application of Principal Component Analysis (PCA) showed that the best results, as far as the extraction of the letters from the background is concerned, are obtained when the second and the third images are merged. The automatic extraction of the letters is feasible to some extent but there is a certain amount of noise with similar characteristics that cannot be removed.     

The rediscovery of ‘the national’ in the 1990s – contexts,new cultural forms and practices in reunified Germany

This article examines how and in which societal and political contexts nationhood is expressed and symbolised in reunified Germany. This ‘rediscovery’ of nationhood since the 1990s mixes new and old motifs of the cultural repertoire of ‘the national’ for different purposes. Three main contexts triggered a rediscovery of ‘the national’ after 1989: reunification, immigration and the retrenchment of the social state. I argue, by analysing ethnographic material and political discourses, that these contexts, on the one hand, rearticulate old forms of ethnic and cultural nationalism and, on the other hand, create new images and symbols of an open civic society and immigration country. There are ‘playful’ forms, such as campaigns of nation branding, that symbolically include the ‘productive’ and ‘useful’ immigrant into the national project. Moreover, such campaigns serve to legitimatise the downsizing of the national state that – according to a neoliberal attitude – relies on a new community spirit of entrepreneurial, ‘activated’ citizens who ‘help themselves’. Thus, focusing on these pluralised renationalisation processes makes evident how polyvalent ‘the national’ still is. It can be employed by those who attempt to ‘reunite’ the East and West Germans, by businesses to sell their goods and ideas and by almost any political orientation, be it right‐wing or left‐wing.     

Opencast mines in South Brandenburg (Germany)—archives of Late Quaternary landscape development and human-induced land use changes

This study outlines the opportunities for geoarchaeological research in active opencast lignite mines in southern Brandenburg (Germany). Studies on extensive outcrops that address both archaeology and soil geomorphology, combined with a geographical information system (GIS) approach, provide unique insights into human-induced environmental changes in Lower Lusatia and generally improve our understanding of landscape dynamics. We present the most recent results from three case studies and review important findings from the last several years. Studies conducted in opencast mines of Cottbus-Nord and Jänschwalde focus on (i) Late Quaternary geomorphodynamics and soil development and (ii) past land use and the legacy of agriculture and woodland use. Our results are similar to those in other regions in Central Europe, but we also observe regional differences caused by the local setting, e.g. intensification of soil erosion coinciding with the expansion of farming of cultivated lands in the Slavic Middle Ages. Our research reveals the largest archaeologically investigated area of historical charcoal production in the Northern European Lowland (NEL). We are clearly only beginning to understand the massive dimensions of charcoal production in the region.     

Social stratigraphy in Late Iron Age Switzerland: stable carbon,nitrogen and sulphur isotope analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them, C₃ plants were found to be the staple food. There are significant differences between males and females in δ¹³C and δ¹⁵N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ¹⁵N values were also observed for different age classes. δ³⁴S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ³⁴S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society.     

Boundary spanning in social and cultural geography

This article situates interactions between German- and English-language social and cultural geographies since the mid-twentieth century within their wider intellectual, political and socio-economic contexts. Based on case study examples, we outline main challenges of international knowledge transfer due to nationally and linguistically structured publication cultures, differing academic paradigms and varying promotion criteria. We argue that such transfer requires formal and informal platforms for academic debate, the commitment of boundary spanners and supportive peer groups. In German-language social and cultural geography, these three aspects induced a shift from a prevalent applied research tradition in the context of the modern welfare state towards a deeper engagement with Anglophone debates about critical and post-structuralist approaches that have helped to critique the rise of neoliberal governance since the 1990s. Anglophone and especially British social and cultural geography, firmly grounded in critical and post-structuralist thought since the 1980s, are increasingly pressurized through the neoliberal corporatization of the university to develop more applied features such as research impact and students’ employability.     

Pigments, dyes, and black enamel—the colorants of reverse paintings on glass

Nondestructive analyses of medieval reverse paintings on glass revealed the same dyes and pigments customarily used in panel paintings. However, there is one exception: the black colorant is not a carbon-based pigment, but black enamel. In this respect, the stylistic as well as the technical influence of stained glass artwork can clearly be seen on reverse paintings on glass. However, there is a crucial difference: in reverse paintings, the black enamel is not fired onto the glass but painted (cold painting). Additional analyses confirmed these findings. Based on these results, the art form “reverse painting on glass” has technically to be characterized as a mixture of “stained glass” and “panel painting” that nonetheless develops into a genre of its own.
