The true role of this splendid, tragic figure. Cagliostro, was a Mystic, Mason and adept at magic, alchemy, and psychic healing. He died at the hands of the Holy Roman Inquisition. Although much has been written against Cagliostro, Trowbridge, through his meticulous researching, comes up with an all together different picture. The object of this book is not so much an attempt to vindicate Cagliostro as to correct and revise, if possible, what I believe to be a false judgment of history. Contents: The Power of Prejudice; Giuseppe Balsamo; Cagliostro in London; Eighteenth Century Occultism; Masked and Unmasked; The Conquest of the Cardinal; Cagliostro in Paris; The Diamond Necklace Affair; Cagliostro Returns to London; Nature’s Unfortunate Child.
