Leonardo da Vinci by Sherwin B. Nulandrtist, anatomist, architect, mathematician, military engineer-few have been as protean as Leonardo. Sir Kenneth Clark called him "the most relentlessly curious man in history." To Nuland, "he is also the historical figure about whom we are most relentlessly curious." In this brief life, Nuland summarizes Leonardo's achievements skillfully. Being a physician (clinical professor of surgery at Yale University), he is particularly interested in Leonardo's pioneering anatomical dissections and drawings. But to him as to other biographers, Leonardo remains essentially elusive. As the English critic Walter Pater said, "he seemed to those about him as one listening to a voice, silent for other men."
