Éliphas Lévi was a 19th-century French occultist and writer, born in 1810 as Alphonse Louis Constant. He is best known for his influential works on magic, mysticism, and the esoteric traditions of Kabbalah and Hermeticism. Lévi's writings helped popularize the concept of modern occultism and inspired many later thinkers and practitioners. Lévi is particularly recognized for his book, "Dogme et Rituel de la Haute Magie," which outlines his theories on magic and the spiritual world. He introduced the idea of the Tarot as a tool for divination and self-discovery, linking it to ancient wisdom and symbolism. His ideas continue to impact contemporary esoteric practices.
