Book excerpt: The Mandaeans are a Gnostic sect that arose in the middle east around the same time as Christianity. What little study of the religion there has been has focused on the ancient Mandaeans and their relation to early Christianity. Buckley examines the lives and religion of contemporary Mandaeans, who live mainly in Iran and Iraq but also in New York and San Diego. She provides a comprehensive introduction to the religion and shows how its ancient texts inform the living religion, and vice versa.
