Heinrich Cornelius Agrippa von Nettesheim was a German Renaissance polymath, physician, legal scholar, soldier, knight, theologian, and occult writer. Agrippa's Three Books of Occult Philosophy published in 1533 drew heavily upon Kabbalah, Hermeticism, and Neoplatonism. His book was widely influential among esotericists of the early modern period, and was condemned as heretical by the inquisitor of Cologne.[1]
