Eliphas Lévi, born Alphonse Louis Constant in 1810, was a French occultist and writer known for his influential works on magic and the esoteric. He is best known for his books, such as Dogme et Rituel de la Haute Magie, which helped popularize the study of Kabbalah and Hermeticism in the 19th century. Lévi's ideas contributed to the revival of interest in the occult during this period. Lévi is often associated with the development of modern Western esotericism and is credited with introducing the concept of the Tarot as a tool for divination. His writings emphasized the importance of symbolism and the interconnectedness of various mystical traditions, influencing later figures in the occult, including Aleister Crowley and the Golden Dawn.
