In literary legend, Faustus is the quintessential occult personality of early modern Europe. The historical Faustus, however, was something quite different: a magus--a learned magician fully embedded in the scholarly currents and public life of the Renaissance. And he was hardly the only one. Anthony Grafton argues that the magus in sixteenth-century Europe was a distinctive intellectual type, both different from and indebted to medieval counterparts as well as contemporaries like the engineer, the artist, the Christian humanist, and the religious reformer. Alongside these better-known figures, the magus had a transformative impact on his social world.

Magus details the arts and experiences of learned magicians including Marsilio Ficino, Pico della Mirandola, Johannes Trithemius, and Heinrich Cornelius Agrippa. Grafton explores their methods, the knowledge they produced, the services they provided, and the overlapping political and social milieus to which they aspired--often, the circles of kings and princes. During the late fifteenth and early sixteenth centuries, these erudite men anchored debates about licit and illicit magic, the divine and the diabolical, and the nature of "good" and "bad" magicians. Over time, they turned magic into a complex art, which drew on contemporary engineering as well as classical astrology, probed the limits of what was acceptable in a changing society, and promised new ways to explore the self and exploit the cosmos.

Resituating the magus in the social, cultural, and intellectual order of Renaissance Europe, Grafton sheds new light on both the recesses of the learned magician's mind and the many worlds he inhabited.
