Multi-scale tribological analysis of the technique of manufacture of an obsidian bracelet from Asikli Hoyuk (Aceramic Neolithic, Central Anatolia)

摘要

Tribological analysis is employed in a pilot study of the technological steps involved in the manufacture of a polished obsidian bracelet from Asikli Hoyuk, an Aceramic Neolithic site in Central Anatolia (8300 e7500 cal. B.C.). The study includes morphological analysis of the bracelet, based on profile measurements, and identifications of wear variations indicated by surface topographic features and parameters. The manufacturing skill that is revealed suggests early appearance of a regional tradition of obsidian working, which reached its full development in the 6th millennium cal. B.C. with the production of various ornamental objects, including mirrors and vessels. The cultural record and location of Asikli Hoyuk make the site important for our understanding of the technological developments during the early Neolithic in Anatolia.
