Leonardo da Vinci (1452-1519) stands as a supreme icon in the history of Western civilization. With much of his work lost or unfinished, the key to his legacy is without doubt to be found in the enormous body of his extant drawings and accompanying manuscript notes. Famous for their beauty and technical virtuosity, Leonardo's drawings were avidly sought by collectors even during his lifetime. This handsome book offers a unified and fascinating portrait of Leonardo as a draftsman, integrating his diverse roles as an artist, scientist, inventor, theorist, and teacher. A chronological framework is also provided in order to shed light on his extraordinary life and career. The essays and entries-written by the world's leading Leonardo scholars-survey the wide variety of drawing types that Leonardo used and also examine a small group of works by artists critical to his artistic development in Florence and to his multifaceted activity in Milan.
