Black Arts by Richard Cavendish
In The Black Arts, Richard Cavendish has not only gathered many fascinating facts from the past and from our own time; he has also presented the philosophy of the black magicians and gives many excellent interpretations of their symbols and rites. He has done all this in such a concise and readable style that the reader is hardly aware of how much effort has gone into this work and how original are many of its ideas and interpretations .
