THE ITALIAN RENAISSANCE 603 great Florentines, Donatello, Ghiberti, and Luca della Rob- bia. The last is especially famed for his terra-cottas ; Ghi- berti, for his bronze doors with their panels full of sculpture in relief in the baptistery at Florence, just across the square from Giotto's tower and Brunelleschi's dome. Donatello had begun his artistic career by 1406. For a score or more of years he worked in Florence on the sculp- tures of the cathedral and campanile and in com- Career and petition with Brunelleschi and Ghiberti.

His frieze of boys run- ning and laughing made Vasari regard him as the "greatest master of bas-relief." His David, depicted as a shepherd
