Isotopic anthropology of rural German medieval diet: intra- and inter-population variability

This study investigates the diet of an eleventh century CE parish community located in northwestern Germany. We assessed the isotopic compositions of human (n = 24) and faunal (n = 17) bone collagen (δ ¹³C_col, δ ¹⁵N_col) and human structural carbonate (δ ¹³C_sc) using skeletal material recovered from the Dalheim cemetery. Traditional interpretation of the isotopic data indicates that Dalheim residents likely relied on a C₃ plant-based diet and consumed some terrestrial animal products without evidence of marine resource input in the diet. Bivariate and multivariate models used as an additional means to assess diet indicate minor consumption of C₄ plant foods in this community. The multivariate-isotope model identified regional similarities and differences in C₄ plant/marine food consumption and in dietary protein sources by comparing data from Dalheim with those of other medieval sites from the published literature. We did not observe sex differences in this population but differences in δ ¹⁵N_col suggest that juveniles consumed the lowest trophic level protein.     

Route persistence. Modelling and quantifying historical route-network stability from the Roman period to early-modern times (AD 100–1600): a case study from the Netherlands

Research on route-network stability is rare. In time, due to cultural and/or natural causes, settlement locations and route orientation shift. The nature of these spatial changes sheds light on the complex interaction between settlements and surrounding natural landscape conditions. This study investigates the stability of route networks in the Netherlands during the past two millennia by determining their persistence through time. Environmental, archaeological and historical data are used to reconstruct and compare route networks. By using network friction, archaeological data on settlement patterns and route networks in combination with historical data (e.g. old maps), we were able to model route-network persistence (not necessarily continuity) from the Roman to early medieval periods (AD 100–800) and from the Early Middle Ages to the Early Modern Times (AD 800–1600). Results show that around 67.6% of the modelled early-medieval routes in the Netherlands are persistent with routes in the Roman period. Covering a much larger surface area of the Netherlands, 24.5% of the early-modern routes show a clear persistence with their early-medieval counterparts. Besides the differences in surface area, this downfall can largely be explained by cultural dynamics, with 71.4% of the early-modern route network following modelled movement corridors already in existence during the Early Middle Ages.     

The Lake Krasnoe obsidian source in Chukotka (Northeastern Siberia): geological and geochemical frameworks for provenance studies in Beringia

Basic data on the geology and geochemistry of obsidian from the Lake Krasnoe source in Chukotka (Northeastern Siberia) are reported for the first time. The data are based on 2009 fieldwork and analytical studies of igneous rock samples. The lake shore and surrounding parts of the Rarytkin Range were thoroughly examined. Two geochemical types of rhyolitic obsidian were recognized for the first time: (1) metaluminous obsidian related to the fine-grained crystalline rocks and (2) peralkaline obsidian corresponding to ignimbrite ash-flows or lapilli-tuffs composition. Both types are related to the final phase of acidic volcanism in the Western Kamchatkan-Koryak Volcanic Belt. Based on the results obtained, we conclude that accumulation of obsidian pebbles in the lake’s modern beach deposits is related to silicic melts that erupted during the late Eocene-early Oligocene in the form of extrusive domes or pyroclastic flows, which are now either covered by Quaternary sediments or located below the water level. The Lake Krasnoe obsidian was intensively used by the ancient populations of Chukotka as a raw material for making stone tools. It was also occasionally transported to Alaska across the Bering Strait in later prehistory. The distances between source and utilization sites are up to 700–1100 km. Geochemical data for Lake Krasnoe obsidian, based on neutron activation analysis and X-ray fluorescence that are presented here, can now be used for provenance studies in the Northeastern Siberia and adjacent regions of northern North America.     

Carnivores as zoonotic parasite reservoirs in ancient times: the case of the Epullán Chica archaeological cave (Late Holocene,northwestern Patagonia,Argentina)

Zoonoses are currently considered as one of the most important threats for Public Health worldwide. Numerous zoonoses known today have occurred since antiquity. Carnivores act as definitive hosts for many intestinal parasites; some of them are responsible for several zoonotic diseases. The aim of this work was to study the parasite remains found in coprolites assigned to carnivores from the archaeological site Epullán Chica (ECh) and to discuss the results from a zoonotic point of view. ECh is located in northwestern Patagonia, Argentina and was occupied since the end of the Late Holocene (～2200 years B.P.). Nine coprolites were examined for parasites. Samples were processed by rehydration in a 0.5 % water solution of trissodium phosphate, followed by homogenization, filtered and processed by spontaneous sedimentation. The macroscopic remains were separated and dried at room temperature and were examined for diet analysis. Six out of 9 coprolites examined were positive for parasites. Representatives of at least 10 parasite taxa were registered. Results are in line with the reconstruction of the scenario of zoonoses in the past and the diseases that the human populations and animals from Patagonia could be exposed. The present study provides the first palaeoparasitological report of carnivore coprolites recovered from the archaeological site Ech and reflects contamination of the cave used by hunter-gatherers with different parasites causative of zoonotic diseases.     

Weak Ties and Expertise: Crossing Technological Boundaries

In this article, we question how new technological traits can penetrate cohesive social groups and spread. Based on ethnographic narratives and following studies in sociology, the hypothesis is that not only weak ties are important for linking otherwise unconnected groups and introducing new techniques but also that expertise is required. In order to test this hypothesis, we carried out a set of field experiments in northern India where the kiln has been adopted recently. Our goal was to measure the degree of expertise of the potters distributed between early and late adopters of the kiln. Our results are discussed in the light of oral interviews. Our conclusions suggest that expertise is a necessary, albeit not sufficient, condition for weak ties to act as bridges and thereby for new techniques to spread. As an example, they explain how turntables could have been adopted by potters from the northern Levant during the third millennium BC.     

“This is Proof”? Forensic Evidence and Ambiguous Material Culture at Treblinka Extermination Camp

In recent years, a forensic archaeological project at Treblinka extermination camp has uncovered significant evidence relating to the mass murder that took place there. A number of questions emerged regarding the provenance and origins of objects discovered as part of this work, and why they had remained undiscovered for over 70 years. These discoveries led to an opportunity to confirm and challenge the history of the extermination camp, and demands (from the public) to view the objects. This paper will outline how archaeologists and artists came together to reflect on these issues, whilst simultaneously providing access to the new findings.     

When Bereaved of Everything: Objects from the Concentration Camp of Ravensbrück as Expressions of Resistance,Memory, and Identity

When survivors from the Ravensbrück concentration camp arrived in Sweden in spring 1945, some of the objects they brought with them from the camp were collected and preserved. These are modest in appearance, but were – as oral testimonies show – invaluable in camp. The concentration camp context of obliteration stretches the limits of interpretation of material culture to its extreme. In this article the objects are discussed as expressions of resistance, memory, and identity. These immaterial values were among the most vital coping strategies used by the prisoners against the dehumanization laid upon them by the camp administration. The material culture was central in enabling, upholding, and realizing these.     

The Small Things of Life and Death: An Exploration of Value and Meaning in the Material Culture of Nazi Camps

The theft of mundane items of material culture from the ground of Auschwitz-Birkenau in 2015 by English schoolboys raises a number of questions about the value of similar items at this and other Nazi camps. This paper explores questions of value, interpretation, and the categorization of objects from such camps, before examining the case study of Lager Wick, a forced labor camp in Jersey. Here, the value of such objects was perceived locally according to criteria very different to those which are commonly applied by archaeologists and people who work in the sphere of heritage and Holocaust education.     

Modeling and Seismic Response Analysis of Italian Code-Conforming Reinforced Concrete Buildings

ABSTRACT

This study investigates the seismic response of reinforced concrete buildings designed according to the current Italian building code. Number of stories, site hazard, presence and distribution of masonry infill panels, and type of lateral resisting system are the key investigated parameters. The main issues related to design and modeling are discussed. Two Limit States are considered, namely Global Collapse and Usability-Preventing Damage. The main aim of the study is a comparison between the seismic response of the buildings, investigated through nonlinear static and dynamic analyses. Irregularity in the distribution of infill panels and site hazard emerge as the most influential parameters.     

The Knife’s Edge of the Present: Archaeology in Turkey from the Nineteenth Century to the 1940s

This paper investigates how archaeology functioned in Turkey from the nineteenth century until the end of the 1940s. In the nineteenth-century Ottoman world, an awareness was raised to acknowledge the power of patrimony. Amidst intense reforms to Westernize the empire, archaeological artifacts were used as a means of Europeanness. The Greek, Roman, and Byzantine pasts of the Ottoman lands were the focus of this era. The foundation of the Turkish Republic in 1923 marked the start of a new project to create a modern nation-state out of a centuries’ old Islamic dynasty. This project rewrote the history of Turkish nation in relation to prehistoric civilizations such as the Hittites and the Sumerians. Archaeology became the primary tool of the Republic to validate the renewed history.
