Papus (Gerard Encausse)'s book originally published in French in 1889 as Le Tarot des Bohémiens: Le plus ancien Livre du monde, was translated into English in 1910 as The Tarot of the Bohemians: The Absolute Key to Occult Science.
Gérard Anaclet Vincent Encausse (July 13, 1865 - 25 October 1916), whose esoteric pseudonym was Papus, was the Spanish-born French physician, hypnotist, and popularizer of occultism, who founded the modern Martinist Order. His nom de plume: "Papus" means "physician."
In 1888, he co-founded his own group, the Kabbalistic Order of the Rose-Croix. Encausse was also a member of the Hermetic Brotherhood of Light and the Hermetic Order of the Golden Dawn temple in Paris.
Encausse visited Russia three times, in 1901, 1905, and 1906, serving Tsar Nicholas II and Tsarina Alexandra both as physician and occult consultant.
