Divination is any ritual and its associated tradition performed in order to ask a more-than-human intelligence for guidance. A universal human practice, it has received surprisingly little academic attention. This interdisciplinary collection by leading scholars in the field is dedicated to fascinating new insights into divination and oracles arising from recent work in anthropology, religious studies, history and classical studies. Central importance is given to the practical and theoretical perspectives of diviners as well as scholars of divination; several contributors are both. This book explores philosophical issues such as the nature of divinatory intelligence, the relationship between divinatory and metaphorical truth, the primacy of ontology over epistemology, the importance of reflexivity in scholarly studies of divination, and astrology as the principal Western form of divination. The ethnographic and historical examples range from contemporary Nigeria, urban Cuba, Mayan Guatemala and the shamanic cultures of the circumpolar Arctic to classical Greece and ancient Judea.
