Éliphas Lévi Zahed, born Alphonse Louis Constant (8 February 1810 – 31 May 1875), was a French esotericist, poet, and writer. Initially pursuing an ecclesiastical career in the Catholic Church, he abandoned the priesthood in his mid-twenties and became a ceremonial magician. At the age of 40, he began professing knowledge of the occult. He wrote over 20 books on magic, Kabbalah, alchemical studies, and occultism.
The pen name "Éliphas Lévi" was an adaptation of his given names "Alphonse Louis" into Hebrew. Levi gained renown as an original thinker and writer, his works attracting attention in Paris and London among esotericists and artists of romantic or symbolist inspiration. He left the Grand Orient de France (the French Masonic organization that originated Continental Freemasonry) in the belief that the original meanings of its symbols and rituals had been lost. "I ceased being a freemason, at once, because the Freemasons, excommunicated by the Pope, did not believe in tolerating Catholicism ... [and] the essence of Freemasonry is the tolerance of all beliefs."
