After these works Pietro went to Tuscany, in order to see the works of the other disciples of his master Giotto and those of Giotto himself; and with this occasion he painted many figures in S. Marco in Florence, which are not seen to-day, the church having been whitewashed, except the Annunciation, which stands covered beside the principal door of the church. In S. Basilio, also, in the Canto alla Macine, he made another Annunciation in fresco on a wall, so like to that which he had made before in S. Marco, and to another one that is in Florence, that some believe, and not without probability, that they are all by the hand of this Pietro; and in truth they could not be more like, one to another, than they are. Among the figures that he made in the said S. Marco in Florence was the portrait of Pope Urban V from the life, with the heads of S. Peter and S. Paul; from which portrait Fra Giovanni da Fiesole copied that one which is in a panel in S. Domenico, also of Fiesole; and that was no small good-fortune, seeing that the portrait which was in S. Marco and many other figures that were about the church in fresco were covered with whitewash, as it has been said, when that convent was taken from the monks who occupied it before and given to the Preaching Friars, the whole being whitewashed with little attention and consideration.
