The Shamans of Prehistory
The good folks at Erowid have posted my review of The Shamans of Prehistory by Jean Clottes & David Lewis-Williams, two prominent authorities on paleolithic cave painting. I am sympathetic to the book’s central argument that many painted caves served a ritual function related to archaic forms of shamanism, but I found their specific cognitive-archaeological model to be under-developed.
Clottes and Lewis-Williams ground their theoretical framework in an altered states model of shamanism and speculate that early shamans may have utilized visionary plants to induce trance states.
