Italian sculptor, son of Agostino di Giovanni, a sculptor in Siena. Like his father, he was continuously active in architecture as well as in sculpture. His documented career runs from 1332, when he was working in the Pieve at Arezzo, to a final mention in 1347. It includes a period as capomaestro, firstly of the Duomo of Orvieto, and secondly that of Siena (1340-45). His one surviving signed work is a small high relief of the Madonna and Child with Angels in the Oratory of S. Bernardino in Siena. The only other important work attributable to him is the hexagonal font for S. Maria del Pieve in Arezzo. //
