content: I teach a course on the history of Witchcraft at a local esoteric shop, and this book was invaluable to my research. Wilmhurst assumes that the reader already has some background in Masonry, so I don't recommend this as a first-read to anyone just beginning to learn about either Masonry or the Mysteries. However, for any serious student of the occult, mysticism, magick, Witchcraft, Masonry or the Mystery traditions, this book is an excellent find. All of the bits and pieces of information I've picked up over the years concerning Masonry make a great deal more sense now.Concerning Wilmhurst's writing style: on a few occasions I had to go back and re-read a passage to catch the meaning, but didn't find the author's language problematic, as some reviewers have complained. However, this book is adapted from a series of lectures, so I will forewarn that it can be repetitive. Overall, I found that the content of the author's material far outweighed the somewhat unfamiliar writing style.
