As his assistant, Uccello was involved in the creation of the great scuptured and gilded bronze doors of the Baptister of the Duomo in Florence, in 1415 he was accepted in to the guild of Medici e Speziali, He is known to have been in Venice from 1425-1431, working with other artists on the mosaics in San Marco. Afterward he settled in Florence, where he painted two large frescoes with scenes from Genesis in the cloister of Santa Maria Novella. Under the influence of Masaccio and Donatello, Uccello became the greatest master of perspective of his generation, and he is one of the most important fore runners of the Florentine Ranaissance.
