Persuasions of the Witches' Craft: Ritual Magic in Contemporary England is a study of several Wiccan and ceremonial magic groups that assembled in southern England during the 1980s. It was written by the American anthropologist Tanya M. Luhrmann of the University of California, San Diego, and first published in 1989. The work would be criticized by later academics working in the field of Pagan studies and western esotericism, who charged it with dealing with those it was studying in a derogatory manner.
