Dreamtime: Concerning the boundary between wilderness and civilization

Dreamtime: Concerning the Boundary between Wilderness and Civilization is an anthropological and philosophical study of the altered states of consciousness found in shamanism and European witchcraft written by German anthropologist Hans Peter Duerr. Dreamtime opens with the premise that many of those accused of witchcraft in early modern Christendom had been undergoing visionary journeys with the aid of a hallucinogenic salve which was suppressed by the Christian authorities. Duerr argues that this salve had been a part of the nocturnal visionary traditions associated with the goddess Diana, and he attempts to trace their origins back to the ancient world, before looking at goddesses associated with the wilderness and arguing that in various goddess-centred cultures, the cave represented a symbolic vagina and was used for birth rituals.
