Early Olmec obsidian trade and economic organization at San Lorenzo

The Olmec were the first complex society to develop in Mesoamerica between 1800 and 600 cal B.C. The earliest large Olmec center during this period was the archaeological site of San Lorenzo which emerged as Mesoamerica's first large ritual and political center between 1400 and 1000 cal B.C. San Lorenzo's growth as a prominent center included the development of long distance trade relationships with adjacent areas of Guatemala and highland Mexico. High precision chemical analysis of obsidian imported for use in the fabrication of cutting tools is used to reconstruct the growth, size and extent of San Lorenzo's interregional exchange networks with areas of Mexico and Guatemala where obsidian occurs as raw material. A total of 852 obsidian artifacts were analyzed to reconstruct changes in obsidian procurement between 1800 and 800 cal B.C. This represents one of the largest samples of sourced obsidian from a Mesoamerican site and it provides a comprehensive picture for the development of interregional trade networks for Mesoamerica's first large Olmec center.     

Estonian Swedish Ethnic Survival – Examples from Nuckö in the Interwar Period

Abstract

A long-term perspective is important in studies of ethnic groups and their opportunities for survival. This case study deals with the Swedish population in Nuckö (Noarootsi), Estonia, during the interwar period. Even though the Swedish population declined as a whole, some villages succeeded in maintaining their Swedish affiliation. Settlement patterns and varying opportunities to own land are important factors behind these differences. The Estonian–Swedish cultural awakening in the interwar period made it easier for people to show their Swedish ethnic identity more openly. Inhabitants in villages that already at the end of the nineteenth century had a large proportion of Estonians in their population, reacted more positively to the state's request that people change their surname as part of the assimilation policy of the 1930s. Even though people in some villages chose to register a change in ethnic status, a change of surname, and even changed their use of language, they may nonetheless have remained committed to their former Swedish ethnicity on a private level. It is crucial to combine different kinds of data, such as church records, censuses and interviews, in order to illustrate the complexities of ethnic identity from a variety of different angles.     

Calcium oxalate AMS C dating and chronology of post-Palaeolithic rock paintings in the Iberian Peninsula. Two dates from Abrigo de los Oculados (Henarejos,Cuenca, Spain)

Since 2005 we have been utilizing accelerator mass spectrometry (AMS) ¹⁴C dating in research on calcium oxalate crusts associated with open air rock art of the Iberian Peninsula. In this paper we present two dates linked with three eye-idol pictographs at Abrigo de los Oculados (Henarejos, Cuenca, Spain). Radiocarbon ages for these motifs agree with the expected iconography-based archaeological chronology. Such oxalate dates could provide an independent basis for evaluating chronological theories for post-Palaeolithic sites, designated in the UNESCO World Heritage List as Rock Art of the Mediterranean Basin on the Iberian Peninsula.     

Māori Textiles from Puketoi Station,Otago, New Zealand

Abstract

A group of Māori textile artefacts were discovered in a rock shelter in the southern South Island of New Zealand in 1895. The assemblage comprised a significant number of textile and textile-related artefacts including large and small bags, footwear and prepared leaf and fibre for textile production. The artefacts were privately owned until the 1920s when they were acquired by the Otago Museum, remaining there until new techniques made further investigation possible. This paper presents information from an interdisciplinary investigation of the Puketoi Station assemblage of textile artefacts, which examined artefact structure, form and function, and materials of construction. Interpretation of these artefacts using contemporary textile analysis methods, traditional weaving knowledge, and recent archaeological research, turns them from static objects into dynamic components of culture. The Puketoi Station artefacts embody and illustrate a unique material culture associated with the late prehistoric southern New Zealand Māori lifestyle.
