"When the works of the chapel before mentioned, were completed, the bishop ordered Buonamico--either for a jest, or for some other cause--to paint, on one of the walls of his palace, an eagle on the back of a lion, which the bird had killed. The crafty painter, having promised to do all that the bishop desired, caused a stout scaffolding and screen of wood-work to be made before the building, saying that he could not be seen to paint such a thing. Thus prepared, and shut up alone within his screen, Buonamico painted the direct contrary of what the bishop had required--a lion, namely, tearing an eagle to pieces; and, having painted the picture, he requested permission from the bishop to repair to Florence, for the purpose of seeking certain colors needful to his work. He then locked up the scaffold, and departed to Florence, resolving to return no more to the bishop. But the latter, after waiting some time, and finding that the painter did not reappear, caused the scaffolding to be taken down, and discovered that Buonamico had been making a jest of him. Furious at this affront, Guido condemned the artist to banishment for life from his dominions; which, when Buonamico learnt, he sent word to the bishop that he might do his worst, whereupon the bishop threatened him with fearful consequences. Yet considering afterwards that he had been tricked, only because he had intended to put an affront upon the painter, Bishop Guido forgave him, and even rewarded him liberally for his labors. Nay, Buffalmacco was again invited to Arezzo, no long time after, by the same prelate, who always treated him as a valued servant and familiar friend, confiding many works in the old cathedral to his care, all of which, unhappily, are now destroyed. Buonamico also painted the apsis of the principal chapel in the church of San Giustino in Arezzo." In the notes of the Roman and other earlier editions of Vasari, we are told that the lion being the insignia of Florence, and the eagle, that of Arezzo, the bishop designed to assert his own superiority over the former city, he being lord of Arezzo; but later commentators affirm, that Guido, being a furious Ghibelline, intended rather to offer an affront to the Guelfs, by exalting the eagle, which was the emblem of his party, over the lion, that of the Guelfs.
