He was born in the castle of Alteville in the commune of Tarquimpol, Moselle, and went to school at the lyceum in Nancy, where he studied chemistry, metaphysics and Cabala.
[1] As a young man, he moved to Paris, and his luxurious apartment became a meeting place for poets, artists, and writers who were interested in esotericism and mysticism.
De Guaita was influenced by the writings of l'Abbé Alphonse-Louis Constant, alias Eliphas Lévi, a prominent French occultist who was initiated in London to rosicrucianism by Edward Bulwer-Lytton in 1854.
Encausse, who went by the pseudonym “Papus”, was a Spanish-born French physician and occultist who had written books on magic, Cabalah and the Tarot.
In the late 1880s, the Abbé Boullan, a defrocked Catholic Priest and the head of a schismatic branch called the “Church of the Carmel” led a “magical war” against de Guaita.
French-Belgian novelist Joris K. Huysmans, a supporter of Boullan, portrayed De Guaita as a Satanic sorcerer in the novel La Bas.
