Textiles and Ethnicity: Tiwanaku in San Pedro de Atacama, North Chile

Examining textiles and other usually perishable artifacts, this paper focuses on textile style as an indicator of ethnicity in archaeological textiles excavated in the cemetery of Coyo Oriental, San Pedro de Atacama, Chile. The Coyo Oriental cemetery was occupied during a period of strong Tiwanaku influence in San Pedro de Atacama (A. D. 500-1000) recognized in artifacts decorated with Tiwanaku images. The analysis presented here identifies at least two distinct textile styles recognized in tunic striping, embroidered selvage treatments, and headgear, a fact that possibly indicates a multiethnic use of the cemetery and oasis of Coyo Oriental. Associated textiles and artifacts suggest that one group represents a local style and ethnic group and the other is a different ethnic group closely related to Tiwanaku. Instead of only minor Tiwanaku influence, I suggest that the oasis was home to a foreign altiplano population who maintained for centuries an ethnic identity visible in a distinct textile style.
