Verrocchio, Andrea del (ändrĕˈä dĕl vār-rôkˈkyō) [key], 1435–88, Florentine sculptor and painter, whose real name was Andrea di Michele di Francesco di Cioni. He was a leading figure in the early Renaissance, and his workshop was a center for the training of young artists in Florence. A virtuoso metalworker, Verrocchio was primarily concerned with the spirited rendering of movement and the elaboration of detail. Many of his paintings are lost. Of the remaining panels, his hand is evident in the Baptism of Christ (Uffizi), assisted by Leonardo da Vinci. In the Pistoia altarpiece he was aided by Lorenzo di Credi. Other attributions are Tobias and the Angel (National Gall., London), two paintings of the Madonna and Child (National Gall., London; Berlin), and a Crucifixion with Saints (Argiano). Most of Verrocchio's achievements in sculpture have survived. His earlier work includes the bold group Incredulity of St. Thomas (Orsanmichele). In 1472 he designed the tombs of Piero and Giovanni de' Medici (San Lorenzo). In the same period he created the graceful Boy with a Dolphin and a lithe portrayal of David (Bargello). He went to Venice (c.1480) to work on the equestrian monument of the condottiere Bartolomeo Colleoni. Verrocchio designed a massive figure of the commander, which was not cast until after the sculptor's death. Examples of his bronze work are in the Metropolitan Museum, and there are two portrait busts of Giuliano and Lorenzo de' Medici in the National Gallery of Art, Washington, D.C.
