With this book the author has assembled together a number of magical spells and treatises from a variety of obscure sources. The result is a great overview of magic from one of the most important figures in Western occultism. When critical at times of Eliphas Levi and Waite's former associate, S. L. MacGregor Mathers, it shows an attempt at being honest with his views on magic. He also covers many of the original early grimoires, sometimes quoting them, and points out flaws in the more recent translations of his time. This is an expanded, updated version of his previous work, The Book of Black Magic. The book is a gold-mine of smaller magical pamphlets published in France in the nineteenth century, which were reproductions of earlier eighteenth-century works, now preserved in this book and valued for their content. All inall this is not so much a book of rituals to perform, which are plentiful and easy to find. It is instead a great reference book on ritual magic, of which only a few good ones exist today. Inthis regard, it is considered one of the best.
