サン・ジョヴァンニ洗礼堂
Giovanni owned two wool workshops in Florence and was a member of two guilds: the "Arte della Lana" and the "Arte del Cambio". In 1402, he served as one of the judges on the panel that selected Lorenzo Ghiberti's design for the bronzes on the doors to the Florence Baptistery. Giovanni also funded the construction of the sacristy in the Church of San Lorenzo in the year 1418. He picked Brunelleschi to be the architect and chose Donatello to create the sculptures. These are just a few of the many contributions that Giovanni made to the art world.
