(active 1351-1364 in Florence)
Italian architect and sculptor perhaps of Lombard origin, active in Florence. His documented works are a Madonna and Child between two angels (1359-64) for the altar of the Oratory of the Bigallo, and a relief (Madonna and Child) in the lunette on the door of the same Oratory (1361). In the latter his manner shows great simplicity, partly derived from Andrea Pisano. The reliefs of the Seven Sacraments on the bell tower of the Santa Maria del Fiore are now also attributed to him, they are earlier than his documented works.
