Heinrich Cornelius Agrippa
Heinrich Cornelius Agrippa von Nettesheim (1486-1535) was a German polymath, physician, legal scholar, soldier, theologian, astrologer, alchemist, and occult writer. He is considered one of the most influential occultists of the early modern period. His book on the occult Three Books of Occult Philosophy was published in 1533, but was condemned as heretical by the inquisitor of Cologne. His work drew heavily upon the influences of Kabbalah, Hermeticism and Neo-Platonism.
