The Mysteries of Free Masonry

The Mysteries of Free Masonry is a book about this infamous secret society, written by the New York businessman William Morgan, who was a mason himself, but turned against them. Morgan claimed to have been made a Master Mason while he was living in Canada, and he appears to have briefly attended a lodge in Rochester. After he was denied participation by members in Batavia, New York, he decided to publically expose secrets of Freemasonry. The book reveals and explains all the degrees conferred in the Royal Arch Chapter and Grand Encampment of Knights Templars-Knights of the Red Cross-of the Christian Mark-and of the Holy Sepulchre.

William Morgan (1774-c. 1826) was a New York businessman whose disappearance and presumed murder in 1826 ignited a powerful movement against the Freemasons, a fraternal society that had become influential in the United States. After Morgan announced his intention to publish a book exposing Freemasonry's secrets, he was arrested on trumped-up charges. He disappeared soon after, and was believed to have been kidnapped and killed by Masons from western New York.
