While Uccello was still quite young he got an important job to do, all by himself. He was asked to paint some frescoes showing stories of different saints for the monks of a Church of San Miniato, on a mountain above Florence. It was a large beautiful church, but the monks at the monastery did not eat expensive food. They only ate bread and cheese. So, Uccello also ate nothing but bread and cheese for breakfast, lunch, and dinner, sometimes made into soup. After a few weeks he thought he was turning into a cheese! So he ran away from the monastery and went back to Florence, leaving his work unfinished.
