Three Books of Occult Philosophy (Book I)

Book I of Agrippa’s "Three Books of Occult Philosophy" lays out the theoretical foundations of Renaissance magic, especially the correspondences among the divine, celestial, and elemental realms. Published in the 1530s, it became one of the most influential texts in Western esotericism; readers will find discussions of natural qualities, elements, planets, numbers, and the metaphysical structure that underlies magical action.

Heinrich Cornelius Agrippa von Nettesheim (1486–1535) was a German polymath, physician, lawyer, and esoteric philosopher whose De occulta philosophia became one of the foundational texts of Renaissance occult thought. His synthesis of natural magic, astrology, Kabbalah, and Neoplatonic ideas deeply influenced later Western esoteric traditions.
