(b Florence, c.1418; d ?Perugia, c.1481).
Florentine sculptor and architect. He was an artist of distinction and originality—the only 15th-century sculptor born in Florence who owed little to Donatello or Ghiberti. His fresh and lively style was linear and graceful, with attractive swirling draperies. Agostino led a peripatetic life, working in various places in north Italy. He is first recorded as a sculptor in 1442, in Modena, and nothing is known of his training or career before this. In 1446 he fled from Florence to Venice after being accused of stealing silver from a church, and from 1449 to 1456 he worked in Rimini on his masterpiece—the sculptural decoration of the Tempio Malatestiano (see Malatesta). His other major surviving work is the series of reliefs, partly in terracotta, on the façade of the Oratory of S. Bernadino at Perugia, on which he worked 1457–61, as architect as well as sculptor. Agostino also executed several delightful reliefs of the Virgin and Child. In 1464 he began a large marble sculpture for Florence Cathedral but abandoned the work; the block was later used by Michelangelo for his David.
