In the area of plastic art, there was far more continuity between the 15th century and the preceding 14th century or trecento. This was largely because Gothic sculpture was more advanced than Gothic painting. A brief look at the reliefs and column statues on the facades and doorways of 12th century cathedrals will testify to the exceptional three-dimensional realism which was being created centuries before Michelangelo. For their part, quattrocento Renaissance sculptors improved on Gothic works by adding new emotion, energy and thought to their statues, borrowed in large part from Classical sculpture. The four greatest figures of Italian Renaissance sculpture were Lorenzo Ghiberti (1378-1455), Donatello (1386-1466), Andrea del Verrocchio (1435-88), and of course Michelangelo. In Siena, the leading sculptor was Jacopo della Quercia (1374-1438).
