So fully were the labours and abilities of the Prior recognized by the Aretines, what with praises, favours, and rewards, and so satisfied and contented was he by this result, that he resolved to adopt that city as his home, and to change himself from a Frenchman into an Aretine. Afterwards, reflecting in his own mind that the art of glass-painting, on account of the destruction that takes place every moment in such works, was no lasting one, there came to him a desire to devote himself to painting, and he therefore undertook to execute for the Wardens of Works of the Vescovado in that city three very large vaults in fresco, thinking thus to leave a memorial of himself behind him. The Aretines, in return for this, presented to him a farm that belonged to the Confraternity of S. Maria della Misericordia, near their city, with some excellent houses, for his enjoyment during his lifetime. And they ordained that when the work was finished, its value should be estimated by some distinguished craftsman, and that the Wardens should make this good to him in full. Whereupon he made up his mind to show his worth in this undertaking, and he made his figures very large on account of the height, after the manner of the works in Michelagnolo's chapel. And so mightily did his wish to become excellent in such an art avail in him, that although he was fifty years of age, he improved little by little in such a manner, that he showed that his knowledge and comprehension of the beautiful were not less than his delight in imitating the good in the execution of his work. He went on to represent the earlier events of the New Testament, even as in the three large works he had depicted the beginning of the Old. For this reason, therefore, I am inclined to believe that any man of genius who has the desire to attain to perfection, is able, if he will but take the pains, to make naught of the limits of any science. At the beginning of those works, indeed, he was alarmed by their size, and because he had never executed any before; which was the reason that he sent to Rome for Maestro Giovanni, a French miniaturist, who, coming to Arezzo, painted over S. Antonio an arch with a Christ in fresco, and for that Company the banner that is carried in processions, which he executed with great diligence, having received the commission for them from the Prior.
