Donato di Niccolò di Betto Bardi (c. 1386 – 13 December 1466), better known as Donatello (English: Italian: [donaˈtɛllo]), was an Italian sculptor of the Renaissance. Born in Florence, he studied classical sculpture and used this to develop a complete Renaissance style in sculpture, whose periods in Rome, Padua and Siena introduced to other parts of Italy a long and productive career. Financed by Cosimo de' Medici, Donatello's David, was the first freestanding nude male sculpture since antiquity.
He worked with stone, bronze, wood, clay, stucco and wax, and had several assistants, with four perhaps being a typical number. Though his best-known works were mostly statues in the round, he developed a new, very shallow, type of bas-relief for small works, and a good deal of his output was larger architectural reliefs.
