One day when two of the monks were walking in the street, they chased Uccello and caught him. They asked him why he had never finished the job. Uccello told them that it was because of the cheese. The monks laughed and promised that he would get better food, if only he would promise to come back and finish what he had started. He came back to finish the frescoes, called "The Lives of the Church Fathers". They are painted in dull colours as a protest against the simple food. Vasari, who tells this story, says that Uccello never ate cheese again in his life.
