Gaspar, chief surgeon to the great duke of Tuscany, was born at Bononia in Italy in 1553. He wrote a Latin treatise entitled Chirurgia Nota de Curtis Membris, in which he teaches the art of engrafting nose, ears, lips, &c. giving representations of the instruments and proper bandages; many, however, are of opinion that he never put his art in practice. But his doctrine is not singular; for Alexander Benedictus, a famous chirurgical writer, has described a similar operation.
