INCA "STONE ANCESTORS" IN CONTEXT AT A HIGH-ALTITUDE USNU PLATFORM

Recent investigations at mountaintop sites around the Ayacucho Basin in the central Andes have identified a distinctive category of isolated Inca stone-faced platforms. Test excavations of the three-tiered platform at one site, Incapirqa/Waminan, revealed a narrow vertical shrift penetrating from the original surface through the fills to a small basin cut into the underlying andesite bedrock. A carefully arranged deposit of three unusual stones was found in this basin. Early Spanish chroniclers give firsthand accounts of a variety of Inca solar rituals observed in Cuzco in which revered objects were deployed. including some sculpted in stone. The detailed descriptions of these stone objects are corroborated by the excavated finds at Incapirqa/Waminan and offer suggestive analogies for interpreting their context and significance.
