Ramon Llull

Ramon Llull (1232–1316) was a Catalan philosopher and mystic. While not strictly a Hermeticist himself, his computational logic system, the Ars Magna, became deeply entangled with Hermeticism and Kabbalah during the Renaissance.

Lullism and Magic

Llull's Ars Magna used rotating concentric wheels containing divine attributes to compute all possible truths about God and nature. In the Renaissance, figures like Giordano Bruno and Cornelius Agrippa hybridized Lull's wheels with Hermetic astrology and Kabbalistic letter permutation (Tseruf). They transformed Llull's orthodox theological computer into an operative magical engine designed to attract celestial spiritus and map the hidden architecture of the universe.
