In his youth, Leonardo da Vinci wrote confidently, "I wish to work miracles." By the time of his death in 1519, when he was sixty-seven and famed throughout Europe, it seemed that he had accomplished wonders aplenty as an artist, engineer, inventor, and scientist. Here, from author Jay Williams, is the moving story of the man behind the Renaissance myth.

The little party came through the air lock bearing a limp figure on an improvised litter. "Who was it this time?" Fenner asked. Gorsline pulled off the transparent hood that covered his head and face, and unzipped his suit. He dug his fingers wearily into his eyes. "Bodkin," he said. "Same as the others." He turned back to the group. "Get him right to the infirmary. Not that it'll do much good," he added, in an undertone, to Fenner. Fenner sighed, glancing at Bodkin on the litter. Behind t...
