Italian painter. He was influential in Florentine painting around the 1350s and his oeuvre is stylistically close to the works of Maso di Banco and the Master of San Lucchese, Allegretto Nuzi and Andrea da Firenze (Andrea di Bonaiuto.) Bonsi seems to have been well respected and as he was listed in the Libro dell'Estimo 1351-52 among the one hundred richest Florentines of his neighbourhood. In 1366, he was invited to become part - together with Taddeo Gaddi, Orcagna and Andrea da Firenze - of a commission appointed to form an opinion regarding the construction of the new cathedral. Several paintings in the Museo dell'Opera del Duomo in Prato, in the church of San Miniato al Monte and in Orsanmichele in Florence are also attributed to Bonsi. //
