Heinrich Cornelius Agrippa von Nettesheim (September 14, 1486 - February 18, 1535) was a German magician, occult writer, theologian, astrologer, and alchemist. Agrippa is perhaps best known for his books. An incomplete list: * De incertitudine et vanitate scientiarum atque artium declamatio invectiva (Declamation Attacking the Uncertainty and Vanity of the Sciences and the Arts, 1526; printed in Cologne 1527), a skeptical satire of the sad state of science. This book, a significant production of the revival of Pyrrhonic skepticism in its fideist mode, was to have a significant impact on such thinkers and writers as Montaigne, Rene Descartes, and Goethe. citation needed] * Declamatio de nobilitate et praecellentia foeminei sexus (Declamation on the Nobility and Preeminence of the Female Sex, 1529), a book pronouncing the theological and moral superiority of women. Edition with English translation, London 1670. * De occulta philosophia libri tres (Three Books Concerning Occult Philosophy, Book 1 printed Paris 1531; Books 1-3 in Cologne 1533). This summa of occult and magical thought, Agrippa's most important work in a number of respects, sought a solution to the skepticism proposed in De vanitate. In short, Agrippa argued for a synthetic vision of magic whereby the natural world combined with the celestial and the divine through Neoplatonic participation, such that ordinarily licit natural magic was in fact validated by a kind of demonic magic sourced ultimately from God. By this means Agrippa proposed a magic that could resolve all epistemological problems raised by skepticism in a total validation of Christian faith. One example of the text, not especially indicative of its broader contents, is Agrippa's analysis herbal treatments for malaria in numeric terms: "Rabanus also, a famous Doctor, composed an excellent book of the vertues of numbers: But now how great vertues numbers have in nature, is manifest in the hearb which is called Cinquefoil, i.e. five leaved Grass; for this resists poysons by vertue of the number of five; also drives away divells, conduceth to expiation; and one leafe of it taken twice in a day in wine, cures the Feaver of one day: three the tertian Feaver: foure the quartane. In like manner four grains of the seed of Turnisole being drunk, cures the quartane, but three the tertian. In like manner Vervin is said to cure Feavers, being drunk in wine, if in tertians it be cut from the third joynt, in quartans from the fourth."
