Luca della Robbia (1399/1400–1482) was an Italian sculptor from Florence, noted for his glazed terracotta roundels, in a technique he apparently developed himself. Though a leading sculptor in stone, after developing his technique in the early 1440s, he mainly produced terracotta thereafter, and passed the technique on to his nephew Andrea della Robbia and great-nephew Giovanni della Robbia. His large workshop produced both cheaper works cast from moulds in multiple versions, and more expensive one-off individually modelled pieces.
The glaze made his creations more durable in the outdoors and thus suitable for use on the exterior of buildings. His work is noted for its charm rather than the drama of the work of some of his contemporaries. Two of his famous works are The Nativity, c. 1460 and Madonna and Child, c. 1475. In stone his most famous work is also his first major commission, the choir gallery or "cantoria" in Florence Cathedral (1431–1438).
Della Robbia was praised by his compatriot Leon Battista Alberti for genius comparable to that of the sculptors Donatello and Lorenzo Ghiberti, the architect Filippo Brunelleschi, and the painter Masaccio. By ranking him with contemporary artists of this stature, Alberti reminds us of the interest and strength of Luca's work in marble and bronze, as well as in the terra-cottas always associated with his name.
The details of Luca della Robbia's youth, training, or early sculpture come mainly from Vasari and other early writers and are somewhat contradictory. He was born in Florence, the son of a member of the Arte de Lana or wool-workers guild. He may have trained as a goldsmith, and then worked with Ghiberti on the famous doors of the Florence Baptistry. He was heavily influenced by Donatello, and in the 1420s was used by the architect Filippo Brunelleschi for sculpture on his buildings. His important commission for the Cantoria of Florence Cathedral came before he joined the sculptor's guild (Arte dei Maestri di Pietra e Legname, for workers in stone and wood) in 1432. According to Vasari, the Medici family were responsible for getting him the commission.
