According to legend, the Egyptian god Thoth gave the Book of Thoth to the people. With its help, the future can be predicted. The Greeks incorporated a version of the book into their culture, the Christians rejected it as pagan. In the 17th century it supposedly influenced Freemasons, in the 18th century tarot card readers. Finally, in the 20th century, the flower power movement of the 1960s was based on its content. But since the actual book has not yet been found, it is doubtful that it ever really existed.
