a skill that was difficult for many of his predecessors, so Uccello also began to acquire a reputation for painting landscapes. He followed this with Scenes from the Life of Noah, also for the Green Cloister. These scenes brought him great fame in Florence. In 1425, Uccello travelled to Venice, where he worked on the mosaics for the façade of San Marco, which have all since been lost. During this time, he also painted some frescoes in the Prato Cathedral and Bologna. Some suggest he visited Rome with his friend Donatello before returning to Florence in 1431. After he returned, Uccello remained in Florence for most of the rest of his life, executing works for various churches and patrons, most notably the Duomo. Despite his leave from Florence, interest in Uccello did not diminish. In 1432, the Office of Works asked the Florentine ambassador in Venice to enquire after Uccello's reputation as an artist. In 1436, he was given the commission for the monochromatic fresco of Sir John Hawkwood. This equestrian monument exemplified his keen interest in perspective. The condottiere and his horse are presented as if the fresco was a sculpture seen from below. It is widely thought that he is the author of the frescoes Stories of the Virgin and Story of Saint Stephen in the Cappella dell'Assunta, Florence, so he likely visited nearby Prato sometime between 1435 and 1440. Later, in 1443, he painted the figures on the clock of the Duomo. In that same year and continuing into 1444, he designed a few stained glass windows for the same church. In 1444 he was also at work in Padua, and he travelled to Padua again in 1445 at Donatello's invitation. Back in Florence in 1446, he painted the Green Stations of the Cross, again for the cloister of the church Santa Maria Novella. Around 1447–1454 he painted Scenes of Monastic Life for the church San Miniato al Monte, Florence. Battle of San Romano paintings Around the mid-1450s, he painted his three most famous paintings, the panels depicting The Battle of San Romano for the Palazzo Medici in Florence, commemorating the victory of the Florentine army over the Sienese in 1432. The extraordinarily foreshortened forms extending in many planes accentuate Uccello's virtuosity as a draftsman, and provides a controlled visual structure to the chaos of the battle scene. Later life By 1453, Uccello was married to Tommasa
