About the author
Erin Pettigrew is the author of Invoking the Invisible in the Sahara, published by Cambridge University Press. The book is a history that examines how esoteric knowledge, spirits, and other unseen forces have shaped social structures, religious norms, and political power in the Sahara region, treating divination and spirit belief as historical evidence rather than folklore. It draws on archival and ethnographic material to trace how claims about an invisible world intersected with governance, authority, and everyday life over time. Published within an academic history list rather than a popular esoteric imprint, the book is aimed at readers interested in African and Islamic history, the anthropology of religion, and the political uses of unseen knowledge, more than at practitioners of divination.
