An overview introducing grimoires, those much-feared medieval and early modern instruction manuals  which circulated underground across Europe. They were prized by magicians and forbidden by the authorities.  At its most basic, a grimoire guides the practitioner step-by-step on how to summon angels, demons, spirits and astral powers such as spirits of the planets. Lecouteux talks the reader through this with clarity and authority. He also provides a concise history of the Western esoteric tradition  and explains the underpinning principles of this grimoire magic.  There is an appendix, too, of magical alphabets and scripts.
