When the Pope had seen these works he was so enchanted by Giotto's style that he commissioned him to surround the walls of St Peter's with scenes from the Old and New Testaments. Giotto therefore began these, and painted the fresco of the angle, seven braccia high, which is above the organ, and many other paintings, of which some have been restored by other artists in our own day, and some have been either destroyed or carried away from the old building of St Peter's during the founding of the new walls and set under the organ. Among these was a representation of Our Lady on a wall. In order that it might not be thrown down with the rest, it was cut out, supported by beams and iron, and so taken away. On account of its great beauty, it was afterwards built into a place selected by the devotion of M. Niccolo Acciancoli, a Florentine doctor enthusiastic over the excellent things of art, who has richly adorned it with stucco and other modern paintings. Giotto is also the author of the mosaic known as the Navicella, which is over the three doors of the portico in the courtyard of St Peter's. This is a truly marvellous work, well deserving its high reputation among all persons of taste. In addition to its excellent design, the apostles are admirably disposed, toiling in different ways in the midst of the tempest, while the winds fill the sail, which bellies out exactly like a real one; and yet it is a difficult task so to unite those pieces of glass to form the light and shade of so real a sail, which, even with the brush, could only be equalled by a great effort. Besides all this, there is a fisherman who is standing on a rock and fishing with a line, whose attitude is expressive of the extreme patience proper to that art, while his face betrays his hope and desire to catch something. Beneath the Navicella are three small arches painted in fresco, but as they are almost entirely effaced, I will say no more about them. All artists, however, unite in praise of these works.
