The work in this chapel finished, the Bishop, either in jest or for some other reason known only to himself, commanded that Buffalmacco should paint him, on one wall of his palace, an eagle on the back of a lion which it had killed. The crafty painter, having promised to do all that the Bishop wished, had a good scaffolding made of planks, saying that he refused to be seen painting such a thing. This made, shutting himself up alone inside it, he painted, contrary to what the Bishop wished, a lion that was tearing to pieces an eagle; and, the work finished, he sought leave from the Bishop to go to Florence in order to get some colours that he was wanting. And so, locking the scaffolding with a key, he went off to Florence, in mind to return no more to the Bishop, who, seeing the business dragging on and the painter not returning, had the scaffolding opened, and discovered that Buonamico had been too much for him. Wherefore, moved by very great displeasure, he had him banished on pain of death, and Buonamico, hearing this, sent to tell him to do his worst; whereupon the Bishop threatened him to a fearful tune. But finally, remembering that he had begun the playing of tricks and that it served him right to be tricked himself, he pardoned Buonamico for his insult and rewarded him liberally for his labours. Nay, what is more, summoning him again no long time after to Arezzo, he caused him to make many works in the Duomo Vecchio, which are now destroyed, treating him ever as his familiar friend and very faithful servant. The same man painted the niche of the principal chapel in the Church of S. Giustino, also in Arezzo. Some writers tell that Buonamico being in Florence and often frequenting the shop of Maso del Saggio with his friends and companions, he was there, with many others, arranging the festival which the men of the Borgo San Friano held on May 1 in certain boats on the Arno; and that when the Ponte alla Carraia, which was then of wood, collapsed by reason of the too great weight of the people who had flocked to that spectacle, he did not die there, as many others did, because, precisely at the moment when the bridge collapsed on to the structure that was representing Hell on the boats in the Arno, he had gone to get some things that were wanting for the festival.
