Neolithic Hedgehogs (Erinaceus europaeus) from the Island of Gotland show early contacts with the Swedish mainland

Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts.Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animal’s origin.From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland.     

Madrid's Retiro Park as publicly-private space and the spatial problems of spatial theory

The scholarly focus on the production of space necessitates a thorough reassessment of the static categories employed in the analysis of spatial processes. Emphasizing space as a process, this essay calls attention to the recent implication of Madrid's Retiro Park in larger processes of capital accumulation. At the same time, it highlights the insufficiency of the tempting yet problematic distinction between public and private space that obtains in easy solutions to the struggles over city-space. As many critics have pointed out, there is design flaw in the idea of public space—it can never explain how a given space, such as a park, comes to be free of the ‘private’ (personal and structural) interests operating throughout its societal context. The story of the Retiro ultimately foregrounds the pivotal role of city-space in the drive for capitalist intercity-competition and suggests that the latter process is insufficiently confronted by idealized notions of the role truly ‘public’ spaces might play in radical democracy and citizenship.     

Context for a carnyx: excavation of a long-lived ritual site at Leitchestown,Deskford, Moray,north-east Scotland

Excavations at the findspot of the Deskford carnyx, a major piece of Iron Age decorated metalwork found in a bog in the early nineteenth century, revealed a special location with a long history. Early Neolithic activity on the adjacent ridge consisted of massive postholes and pits, suggesting a ceremonial site. An Early Bronze Age cremation became the focus for a feasting event in the Middle Bronze Age. Around this time, peat began to form in the valley, with vessels of pot and wood smashed and deposited there; these activities on ridge and bog may be connected. Activity in the bog intensified in the later Iron Age, when offerings included quartz pebbles, the dismantled carnyx head, and two unusual animal bone deposits. The ridge was cut off at this period by a complex enclosure system. This Iron Age activity is interpreted as communal rituals at a time of increasing social tension. The site’s significance in this period may stem from its unusual landscape character, with flowing water to one side and a bog to the other. The area saw occasional activity in the Early Medieval period, but its significance had waned.     

New models of North West European Holocene palaeogeography and inundation

This paper presents new 500 year interval palaeogeographic models for Britain, Ireland and the North West French coast from 11000 cal. BP to present. These models are used to calculate the varying rates of inundation for different geographical zones over the study period. This allows for consideration of the differential impact that Holocene sea-level rise had across space and time, and on past societies. In turn, consideration of the limitations of the models helps to foreground profitable areas for future research.     

The effect of charring and burial on the biochemical composition of cereal grains: investigating the integrity of archaeological plant material

Stable isotope analysis of charred archaeobotanical cereal grains has the potential to provide direct evidence of crop growing conditions in the past and to refine palaeodietary predictions. If isotope values of archaeobotanical material are to be considered robust, it is necessary to characterise the compositional changes associated with their charring and burial. This study used a suite of analytical techniques, including FT-IR and solid state ¹³C NMR, to characterise changes in the biochemical composition of modern einkorn grains with heating at 230 °C for 2 h, 4 h, 8 h and 24 h, encompassing conditions that replicate their undistorted ancient counterparts. The biochemical composition of archaeobotanical charred einkorn grains was also investigated by FT-IR and solid state ¹³C NMR in order to assess the changes in composition which occur during burial. Results of FT-IR and solid-state ¹³C NMR show that heating of modern einkorn grains resulted in Maillard reactions between cereal proteins and starch, forming high molecular weight melanoidins, which contain both alkyl and aromatic carbon. Loss of low molecular weight carbon and nitrogen-containing volatiles resulted in a slight but non-systematic increase in the δ¹³C values and a systematic increase of 0.8‰ in the δ¹⁵N values of the charred einkorn grains. Solid-state ¹³C NMR shows that the ancient charred einkorn grains consisted entirely of aromatic carbon and retained a similar proportion of nitrogen to their modern 24 h charred counterparts, despite a significantly lower concentration of amino acids. This indicates that the amino acid nitrogen in the ancient charred grains was retained in the stable melanoidins whose polymeric structure makes them resistant to subsequent degradation.
