Chemical Alteration of Lithic Artefacts: an Experimental Case Study on the effect of Guano on Stone Flakes and Its Contextualization in the Archaeological Assemblage of Azokh Cave (Southern Caucasus)

Chemical weathering of archaeological material is well known; however, while there have been a number of experimental studies demonstrating different types and degrees of chemical alteration on faunal remains, little attention has been paid to stone tools, and the few studies that exist relate mainly to siliceous materials and water‐induced chemical alteration. Azokh Cave, located in the South Caucasus, contains a Middle Pleistocene to Holocene infill, and detailed macro‐ and microscopic examination of the lithic assemblages recovered there indicates potential chemical weathering of the stone artefacts. The cave is also currently home to one of the largest bat colonies in the region, and their guano forms a significant component of the infill of the inner galleries. Based on these two factors, an experimental pilot study was set up to artificially chemically alter a range of stone flakes produced specifically for the task, in order to determine the nature and likely cause of weathering. The experimental flakes, produced from different raw materials, were buried in fresh bat guano for up to two years. The results reported herein demonstrate that in a relatively short time, the highly acidic composition of bat guano strongly affects calcium‐bearing rocks (e.g., limestone, basalt) altering their entire surface. Similar comparisons may be made with chemical alteration evident on archaeological lithics from Azokh Cave, suggesting that bat guano has played a significant role in diagenetic alteration.     

The Bagpipe Player in the Cradle,an Irish Changeling Motif

This study investigates the motif of music, and particularly of bagpipe-playing, in Irish changeling folk narratives, an aspect which has seldom so far been researched. After an overview of its corpus, this article will detail the characteristics of ‘Changeling Piper’ tales to then look at the symbolism of the bagpipe in this context. A final analysis of the dissemination of the sources on changelings playing the pipes suggests that this motif is particular to Ireland.     

LOCAL FOOD,URBANIZATION, AND TRANSPORT‐RELATED GREENHOUSE GAS EMISSIONS

We argue that “buying local” does not necessarily reduce transport‐related greenhouse gas emissions, even if production technologies and yields are homogeneous in space. We develop a partial‐equilibrium model of rural‐urban systems where the spatial distribution of food production within and between regions is endogenous. We exhibit cases where locating some food production in the least‐urbanized regions results in lower emissions and higher welfare than if all regions are self‐sufficient. The optimal spatial allocation of food production does not exclude the possibility that some regions should be self‐sufficient, provided that their urban population sizes are neither too large nor too small.     

Embroidery as a Means of Diplomacy: The Artisans’ Part in a Royal Marriage Proposal, 1560–1561

The use of fashionable dress played an important part in early modern dynastic politics. In this paper, the diplomatic efforts to engineer a marriage between Erik XIV of Sweden and Elizabeth I of England are used as an example of the interrelations of textiles and diplomacy. Parallel to their negotiations in London, the Swedes organised the production of luxury goods and set up temporary workshops on the spot. The study looks at the Swedish embroidery workshop in London, using written records to investigate its organisation and production, and to discuss artisanal skills and the transnational element in employment in a royal workshop. It is suggested that the entire enterprise was a diplomatic practice, designed to enable the Swedes to draw attention to their presence in London and make their consumption visible on all possible levels.     

Feasting and Building an Urban Society at Cerro Jazmín,Oaxaca, Mexico

Here we present new excavation data from the urban site of Cerro Jazmín, Oaxaca, Mexico. Based on a comparative analysis of ceramic, faunal, botanical, and architectural evidence collected from a prominent city sector and a contemporary residence, we argue that feasting took place in the Sunken Patio Sector in the Late and Terminal Formative periods. Feasting strategies in an earlier occupation of the city sector employed a largely exclusionary strategy, giving way to a more corporate strategy in a later occupation. We take the findings from the Sunken Patio feasting complex as evidence of the formalization of Cerro Jazmin’s urban, regional role as a site of civic-ceremonial activity. Participation in this meaningful act of food consumption may have served to cement communal ties in a nascent urban society.     

The Holocene fluvial history of the Tremithos river (south central Cyprus) and its linkage to archaeological records

This study aims to reconstruct the Holocene fluvial history of the Tremithos river, south central Cyprus and examine linkages to regional and local archaeological records. Three stratigraphic profiles (Sp1, Sp2 and Sp3) located in the lower valley have been investigated using sedimentology and magnetic parameters. The ¹⁴C dating of 10 samples reveals mid-Holocene ages for Sp1 and Sp2, while the upper most part of Sp3 can be attributed to the early to mid-Holocene. Two main phases of vertical accretion have been recognised: the first, recorded in the lower most part of Sp3, could not be dated but might relate to the late Glacial period. It is not associated with any archaeological artefacts. The second, recorded in all profiles, dating from ca. 5000 to ca. cal 2800 BC, spans the Late Neolithic Sotira (cal 4800/4000 BC) and Late Chalcolithic (cal 2900–2500 BC) cultures. The sediments of Sp1 and Sp2 are up to 8–10 m thick and mainly composed of fine material. However, an intercalated phase of coarse sediment has been identified at the beginning of the third millennium BC, indicating a sudden change in river dynamics, potentially associated with the 5.2 ka rapid climate change regional event. Typical mid-Chalcolithic (ca. cal 3300–3050 BC) ceramics found in a palaeosol in Sp2 indicate for the first time human occupation of the Tremithos river terraces. Two other palaeosols have also been recognised in Sp3 and radiocarbon dated to ca. cal 5600–4100 BC and ca. cal 2900–2600 BC, respectively. These results make it possible to propose a palaeogeographic reconstruction of the Holocene evolution in the Tremithos valley and to make a preliminary assessment of the relative roles of tectonics, climate and anthropogenic forcing.
