This work is one of a number of manuscripts crafted towards the end of the 1800s well into the 1920s containing material related to all aspects of the occult; mesmerism, ceremonial magic, the black arts, talismans, and more. What is interesting, here, is that all of the above and more are contained in one work, instead of separately.Speaking of everything from fortune telling to folk healing, the Book of Forbidden Knowledge is perhaps better classed as a modern grimoire than most contemporary works of similar origin; the paper covers of any of a number of competing Victorian and Edwardian era titles.
