(b Siena, 1447; d Siena, 1500).
Sienese painter and sculptor. He was probably a pupil of Vecchietta and worked in partnership with Francesco di Giorgio in the early 1470s. Most of his paintings are representations of the Virgin and Child with Saints, but one of his finest works is a Portrait of a Lady (c.1490, NG, Washington). He continued the elegant and refined Sienese tradition that stretched back to Duccio and his work is particularly noted for its delicate colouring. His work as a sculptor included a number of commissions for Siena Cathedral.
