Sculptor, active from 1543 in Venice. There he was pupil of Jacopo Sansovino whom he succeeded as the leading monumental sculptor in the city, continuing his master's style but giving it a more Mannerist character.
He worked extensively in the Doges' Palace both before and after the fire of 1577, executing, for example, the stuccoed ceiling of the Scala d'Oro (1555-59) and three statues in the Sala delle Quattro Porte (1587). Other examples of his work are in many Venetian churches. He also produced small elongated bronze figures of great elegance and realistic portrait busts of Venetian personalities.
