Tracing the source of Late Neolithic Spondylus shell ornaments by stable isotope geochemistry and cathodoluminescence microscopy

Determination of the source of Spondylus objects is essential for the interpretation of Late Neolithic exchange systems and the social role of shell ornaments. We performed stable isotope analysis combined with cathodoluminescence microscopy study on ornaments (beads, bracelets) made of Spondylus shells excavated at the Aszód-Papi földek archaeological site in Hungary, to define their origin. For comparison Spondylus finds from Neolithic sites of Greece, modern Spondylus shells from the Aegean and the Adriatic, as well as fossil Spondylus and Ostrea shells from the Carpathian Basin were also examined. Oxygen isotope composition of Spondylus finds from Aszód ranges between ?1.9 and 2.1‰ and overlaps with the oxygen isotope range of shell objects from other Neolithic sites. Modern Spondylus shells from the Aegean and the Adriatic show overlapping δ¹⁸O values with one another and with the Neolithic objects; while recent shells of the Black Sea clearly are separate isotopically from the Mediterranean ones and most of archaeological artefacts. Spondylus shells from the Aszód site have Mediterranean origin; their source can be the Aegean or the Adriatic. Based on a former strontium isotope study the use of fossil Spondylus shells is excluded as raw material used for ornaments, however, in recent years the use of fossil shells was reintroduced. The shell ornaments from Aszód-Papi földek and the fossil oyster shells collected from the Carpathian Basin exhibit some overlapping oxygen isotope values; however, cathodoluminescence microscopy indicates that the Spondylus objects retained their original aragonite material. Diagenetic calcite, which occurs typically in the fossil shells, was not detected in the ornaments suggesting that the studied objects were made of recent shells. Calcitic parts observed in some Spondylus objects are not related to fossilisation.     

Archaeology,assistance, and aggression along the Euphrates: reflections from Raqqa

ABSTRACT

This paper traces the cultural missions and salvage archaeology programs along the Euphrates River around Raqqa from the 1950s onwards. We suggest that the varied investments from international expeditions, conservation programs, and technical assistance in Syria have an important, untold history that is relevant to recent developments and conflicts in northern Syria. We explore the intersecting practices of archaeology and assistance, illuminated by archives drawn from international agencies such as UNESCO, as well as companies, consultants, bureaucrats, and archaeologists. Our focus is upon foreign intervention around imperiled heritage, considering not only internal politics but also UNESCO’s 1960s shift from fully funded campaigns to global appeals reliant on foreign governments, corporations, and universities. The outsourcing of salvage allowed specific patrons – national and international – to privilege particular pasts; and it is these histories and legacies that further require us to reassess the place of Raqqa in the current civil war.     

Connecting global health interventions and lived experiences: suspending ‘normality’ at funerals in rural Tanzania

In this paper, we use the funeral space and its liminal nature as a milieu for exploring how a ‘modern’ health intervention, the mosquito bednet, is negotiated by its recipients in relation to its (non)-usage in such spaces. With a focus on sleeping arrangements at funerals and drawing on empirical data from participants living in rural southern Tanzania, we discuss how the bednet is linked to the notion of being unsympathetic to the death. Viewed as a symbol of modernity and a reflection of wealth and individual pride, the bednet becomes physically and symbolically inappropriate in the more sacred, ‘in-between’ site of the funeral. We also uncover how risk perceptions regarding malaria transmission are re-cast in funeral spaces, with socio-cultural practices and health-related behaviours being simultaneously ‘risky’ for individual mourners and reinforcing in terms of group social cohesion. As individual mourners' concerns about malaria risks are suspended, notions of pain and discomfort come to the fore as part of the mourning process and respect for the deceased.

Pottery politics: Late Classic Maya palace production at Motul de San José, Petén,Guatemala

Archeologists often rely heavily on stone monuments, architecture, settlement patterns, and written texts to reconstruct ancient political systems. In this paper we focus on the role of polychrome pottery as both a reflection of and critical component in the production of power relations. We present rare direct evidence of polychrome pottery production recovered from the Maya site of Motul de San José, the presumed Late Classic (ca. 600–900 AD) capital of the epigraphically-recognized Ik’ polity. Our contextual analysis of production debris and tools complement on-going polychrome vessel style and chemical analyses of Ik’ Style polychrome vessels to suggest that Motul de San José’s royal court was an important center in the manufacture of Ik’ Style polychrome pottery. These elaborate vessels indexed the political history, power, and networks of the Ik’ polity. By combining archeological, iconographic, and epigraphic data of polychrome pottery, we shed light on Motul de San José’s internal political-economic dynamics as well as its macro-political alliances and tensions with other polities.     

Ergosterol (5, 7, 22-ergostatrien-3β-ol) as a potential biomarker for alcohol fermentation in lipid residues from prehistoric pottery

In this paper we explore the potential use of ergosterol (5, 7, 22-ergostatrien-3β-ol) as a possible biomarker for yeast and alcohol fermentation, applying the analytical technique previously used routinely in Swedish archaeology for the analysis of lipid residue in prehistoric pottery. Taking note on the connection between brewing, baking and agriculture the frequency of vessels showing gas chromatography mass spectrometry traces of this compound in lipid residues from a clearly agricultural Bronze Age/Early Iron Age population was compared with the same signal in a clearly non-agricultural Neolithic foragers pottery population. The result shows a small but statistically significant difference between the two populations, indicating a connection between the presence of ergosterol in lipid residues from pottery and agriculture. The results are also discussed in terms of varying cleanliness, degradation, deposition conditions and contamination. Suggestions for future research include the use of a more sensitive analytical protocol in order to improve detection limits and to include materials from clear agricultural Neolithic vessel populations.
