His best-known works include the bronze Christ and St Thomas (c.1465-83) at Orsanmichele, a bronze statue of David (c.1476) (modestly clad, in contrast to Donatello's provocative nude David), and the Colleoni monument (1479-88) in Venice, which is the first equestrian statue in stone to depict one of the horse's legs in a raised position. In other words, the entire weight of the statue is carried on three legs rather than four. The statue is also notable for the carefully-observed expression of stern command upon Colleoni's face.
