Andrea del Verrocchio (c. 1435 – 1488), born Andrea di Michele di Francesco de' Cioni, was an Italian painter, sculptor, and goldsmith who was master of an important workshop in Florence. He became known by his nickname "Verrocchio" which in Italian means "true eye" a tribute given to him for his artistic achievement. Few paintings are attributed to him with certainty, but a number of important painters were trained at his workshop. His pupils included Leonardo da Vinci, Pietro Perugino and Lorenzo di Credi. His greatest importance was as a sculptor and his last work, the equestrian statue of Bartolomeo Colleoni in Venice, is generally accepted as a masterpiece.
