The Book of Forbidden Knowledge: Now Available!
The Book of Forbidden Knowledge should in no way be judged based on its era and type of manufacture. A simple paperback released at the dawn of the 20th century, it's really more of a modern grimoire influenced by the Oracle/Napoleonic tradition than it is a hand guide of trickery typical of that late Victorian age.
Covering charms, talismans, fortune telling, prognostication, physiognomy, mesmerism, seances, and more, it's similar to Hohman's Pow Wows in the 1800s or the Petit Albert of the 1700s. That is to say, a compilation of many types of lore from multiple backgrounds; indeed the similarity it shares with these two works leads me to believe that it borrows some of its content from each. It's an extremely good work; far better than I expected when I first saw the cover and presumed it to be silly.
