In this book, the exhaustive history of secret societies is adjacent to the legends that excite the imagination about Christians Rosenkreuz and John Dee, about Paracelsus and Saint-Germain, about the Holy Grail and the treasures of the Templars. What is the mission of the semi-legendary brotherhood, which has chosen as its symbol the mystical Rose ascended to the Cross? Did this brotherhood really keep the secrets of the deepest antiquity, or did it arise only in the 17th century, becoming a failed attempt to spiritualize materialistic science and influence the fate of mankind?
