The Grimoire Encyclopaedia is a work of unparalleled magical scholarship which expands the field of grimoire study far beyond its previous boundaries. Including one hundred chapters on individual grimoires and important books, a table of the spirits found in those books, and fourteen appendixes, these two volumes provide a fresh panoramic view and the most extensive collection of resources ever collected on the grimoire tradition.

Volume 1 offers information on the period before the grimoires as well as a timeline of the books discussed, the spirit hierarchies found in the grimoires, the methods and best practice of conjuring spirits, an extensive table of spirits, and the encyclopaedic entries themselves. Stephen Skinner calls The Grimoire Encyclopaedia 'a work of incredible scholarship by someone who truly understands his subject...' that 'deserves to be on the bookshelves of all magicians and scholars of grimoire studies.'

David Rankine offers a comprehensive system of exploring the grimoires, from the intensive spirit list to a detailed look at magical tools, magic circles, and more. Spanning hundreds of years and including texts both familiar and strange, this resource will become an instant classic in the field of grimoire studies.
