Cranial vault modification as a cultural artifact: a comparison of the Eurasian steppes and the Andes

This paper details the practice of intentional cranial vault modification in the Eurasian steppes as well as in the pre-Columbian Andes focusing on the similarities and differences in how the practice was used to respond to changes in society. The appearance of vault modification in the steppes and the forms seen in the cemeteries of the Syr Darya and Amu Darya River deltas are discussed. Temporal changes in the pattern of modification are also investigated, especially the dramatic homogenization of the custom resulting from the conquests of the Huns. This is contrasted with incidences of cranial modification in the south-central Andes, including the appearance of deliberate head shaping as well as shifts in the practice during the expansion of the Bolivian Altiplano state of Tiwanaku. Similarities in the use of cranial vault modification between these unrelated areas and in the alterations of the practice resulting from foreign contact are considered in light of vault modification's role as a malleable cultural artifact.
