Oldest obsidian bracelet reveals amazing craftsmen's skills in the eighth millennium BC
Researchers from the Institut Français d'Etudes Anatoliennes in Istanbul and the Laboratoire de Tribologie et de Dynamiques des Systèmes have analyzed the oldest obsidian bracelet ever identified, discovered in the 1990s at the site of Aşıklı Höyük, Turkey. Using high-tech methods developed by LTDS to study the bracelet's surface and its micro-topographic features, the researchers have revealed the astounding technical expertise of craftsmen in the eighth millennium BC. Their skills were highly sophisticated for this period in late prehistory, and on a par with today's polishing techniques. This work is published in the December 2011 issue of Journal of Archaeological Science, and sheds new light on Neolithic societies, which remain highly mysterious.
