by Jean-Pierre Chaumeil

Since 1971, Jean-Pierre CHAUMEIL, a French ethnologist, has spent several periods in the Peruvian Amazon, especially among the Yagua of the northeastern region, with whom he lived for more than three years together with his wife. His primary interest is the comparative study of shamanism and, more generally, everything surrounding the new forms of religiosity in the Amazon. He is the author of several books, among them “Voir, savoir, pouvoir” (Ed. de l’EHESS, Paris, 1983) and “Ñihamwo” (CAAAP, Lima, 1987). A research officer at the National Center for Scientific Research (CNRS), he belongs to its Amerindian Anthropology Research Team (France).
