The fall of Lucifer, and that of the rebel angels who descended upon the daughters of men, comprise the foundation myth of the Western occult tradition. Lucifer: Princeps is a study of origins, a portrait of the first ancestor of witchcraft and magic. In tracing the genealogy of our patron and prince, the principles that underlie the ritual forms that have come down to us, through the grimoires and folk practices, are elucidated. The study draws on the extensive literature of history, religion and archaeology, engaging with the vital discoveries and advances of recent scholarship, which render previous works on Lucifer, however well intentioned, out of date. A concomitant exegesis of the core texts conjures the terrain and koine of the Ancient Near East, the cradle cultures and language of his nascence. Of critical importance are the effaced cultures and cults that lie behind the Old Testament polemics, viz. those of Assyria, Ugarit and Canaan, as well as Sumeria, Egypt and Greece; they provide the context that give meaning to what would otherwise be an isolated brooding figure, one who makes no sense without being encountered in the landscape.
