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. This book 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.
