Three Books of Occult Philosophy
Three Books of Occult Philosophy (De Occulta Philosophia libri III) is Heinrich Cornelius Agrippa's study of occult philosophy, acknowledged as a significant contribution to the Renaissance philosophical discussion concerning the powers of ritual magic, and its relationship with religion.
The first book was printed in 1531 in Paris, Cologne, and Antwerp, while the full three volumes first appeared in Cologne in 1533.
Content
The three books deal with elemental, celestial and intellectual magic. The books outline the four elements, astrology, Kabbalah, numerology, angels, names of God, the virtues and relationships with each other as well as methods of utilizing these relationships and laws in medicine, scrying, alchemy, ceremonial magic, origins of what are from the Hebrew, Greek and Chaldean context.
These arguments were common amongst other hermetic philosophers at the time and before. In fact, Agrippa's interpretation of magic is similar to the authors Marsilio Ficino, Pico della Mirandola and Johann Reuchlin's synthesis of magic and religion, and emphasizes an exploration of nature.
Despite being an old and venerated source, the book does contain errors, including an incorrect spelling of the Hebrew names of God in the section devoted to the Archangels of the Zodiac.
