The Arbatel of Magic
Arbatel de Magia Veterum
The Arbatel of Magic is unique among grimoires: it is a Christian magical text. Published openly in Basel in 1575, it describes not demonic conjuration but communication with seven Olympian spirits — planetary governors of the cosmic order who are willing to work with sincere practitioners. The book opens not with threats and bindings but with exhortations to virtue, prayer, and trust in God.
