Exploring the history and creation of a ?witch?s familiar,? also known as a spirit double or guardian spirit, Maja D?Aoust shows how there is much more to these supernatural servant spirits and guardians than meets the eye. She reveals how witches are not the only ones to lay claim to this magician?s ?assistant? and examines how the many forms of witch?s familiars are well known in folklore throughout Europe and America as well as in shamanic and magical traditions around the world, including Africa, India, and China.
