With this book a number of magical spells and treatises from a variety of obscure sources have been assembled. The result is a great overview of magic from one of the most important figures in Western occultism. Although critical of Eliphas Levi and his former associate, S. L. MacGregor Mathers, he is being honest with his views on magic. 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. Contains 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. Considered one of the best reference books on ritual magic that exist today.
