Stanislas De Guaita (6 April 1861, Tarquimpol, Moselle – 19 December 1897, Tarquimpol) was a French poet based in Paris, an expert on esotericism and European mysticism, and an active member of the Rosicrucian Order. He was very celebrated and successful in his time. He had many disputes with other people who were involved with occultism and magic. Occultism and magic were part of his novels.
De Guaita came from a noble Italian family who had relocated to France, and as such his title was 'Marquis', or Marquess. 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. 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. In the 1880s, Guaita published two collections of poetry The Dark Muse (1883) and The Mystic Rose (1885), which became popular.
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. Eliphas Lévi was also initiated as a Freemason on 14 March 1861 in the Grand Orient de France Lodge La Rose du Parfait Silence at the Orient of Paris. De Guaita became further interested in occultism after reading a novel by Joséphin Péladan which was interwoven with Rosicrucian and occult themes. In Paris, de Guaita and Péladan became acquainted, and in 1884, the two decided to try to rebuild the Rosicrucian Brotherhood. They recruited Gérard Encausse to help rebuild the brotherhood. 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.
