"The Greek magical papyri" is the name given by scholars to a collection of magical spells and formulas, hymns, and rituals from Greco-Roman Egypt. Dating from the second century B.C. to the fifth century A.D., these fascinating papyri have survived not only the forces of nature but the systematic efforts of ancient official cults to destroy such documents. They provide a rare glimpse into the vast religious “underworld” of late classical and early Christian times. This new translation has been brought up to date and is now the most comprehensive collection of this literature, and the first ever in English. It is an invaluable resource for scholars in a wide variety of fields, from the history of religions to the classical languages and literatures, and it will fascinate those with a general interest in the occult and the history of magic.
