Mummies and Mortuary Monuments: A Postprocessual Prehistory of Central Andean Social Organization

In this boldly revisionist book, however, William Isbell persuasively argues that the ayllu developed during the latter half of the Early Intermediate Period (around A.D. 200) as a means of resistance to the process of state formation. Drawing on archaeological evidence, as well as records of Inca life taken from the chroniclers, Isbell asserts that prehistoric ayllus were organized around the veneration of deceased ancestors, whose mummified bodies were housed in open sepulchers, or challups, where they could be visited by descendants seeking approval and favors. By charting the temporal and spatial distribution of chullpa ruins, Isbell offers a convincing new explanation of where, when, and why the ayllu developed.
