This work is quite simply titled- a compilation of various lore coming in the form of stories related by the (in)famous Elliot O'Donnell, related to various cultures as wide reaching as France, Denmark, and Siberia.The concept of lycanthropy here finds a somewhat sympathetic mind- for the material is presented in loose connection with theories about existence popularized by the author- of spirits of various sorts, and of the literal existence of sorcery able to produce werewolves, among other things. This work contains recipes for literally becoming a lycanthrope, all of which are drastically psychoactive.
