Eliphas Levi (1810-1875) The pseudonym for Alphonse Louis Constant, a French occultist who is credited for reviving interest in magic in the 19th century. Although Levi studied magic, he was considered to be more of a commentator on the subject than an adept even though he professed to have practiced necromancy several times.
