The book reveals to the reader the widest range of names and phenomena significant in esotericism of the last three centuries. Here is Montfaucon de Villars, stabbed by unknown persons on the Lyon road for divulging secrets about contacts between people and the spirits of the elements - gnomes, undins, sylphs and salamanders. And Gerard de Nerval, who discovered the secrets of the powerful Zion Priory. Both Gustav Meyrink and Rene Guenon, the founder of a special trend in esotericism, traditionalism, are dedicated to "high rank." And warlock Claude Seignol, Howard Philips Lovecraft, Mircea Eliade, Georgy Gurdjieff, Louis Povel... In short, Yuri Stefanov's book is certainly a milestone in the history of Russian esotericism.
