This book contains extremely valuable and interesting information regarding the Cultus Sabbati and its publications. This book is not a "book of power" by any means, and you should not expect it to provide you with anything of that sort. But the information this book has is well worth it for anyone deeply interested the ideas and sorcerous practices found in the books published by Xoanon and it's ancillaries. This book contains excerpts of private correspondences between Andrew Chumbley and others, influences of Kenneth Grant's Typhonian Currents, information about interior and private publications of the Cultus Sabbati, never before (or elsewhere) published pictures and artwork of rare works, excerpts from the most of the works that are described; and most importantly a history of the process that informed the manifesting and creation of each of Xoanon's published works, both in the psycho-spiritual process of the author's drawing them forth and the physical artistic process of it's creation and binding. Much of the information in this book will also work as an excellent supplement to anyone working with any of the texts whose history is revealed in this work. The book ends with a brief essay by Daniel Schulke titled "Trajectories of Magical Text in Charming Traditions" whether they emanate from oral culture, popular folk works, or grimoires.
