The so-called "Book of Black Magic" is more or less a compendium of some of the more infamous medieval grimoires such as the Red Dragon, the Grimoire of Honorius, etc. The book is worth the price for the sheer ammount of knowledge contained within. The general occult public is sometimes hardpressed to gain access to medieval manuscripts and grimoires or is not willing to pay an exorbitant fee for copies form the Bristish Museum. Even then, one must contend with the Middle English dialect (although a company called IGOS sells translated copies of many noteworthy grimoires) and the occaisional swear, crack, or scorch mark on the document. It is for this reason that the "Book of Black Magic" is a worthy addition to your shelf. Although the information is presented lucidly and translated the reader must still contend with the horrible illustrations of Waite (a true disgrace to produce a book with such poorly drawn sigils and seals), not to mention his sheer verbosity. In effect it is a trade-off......we gain this pure compendium knowledge at the high price of reading the pompous (and often inane) outpourings of A.E. Waite. Had this book been written as a sheer compilation without the annoying commentaries by Mr. Waite it would have been a 10. If you can filter his footnotes (which are longer than the book) it is a most worthwhile experience.
