We are now arrived at the age of Giotto, and the first who presents himself to us is Pietro Cavallini, who was instructed by Giotto, in Rome,[8] in the arts of painting and mosaic, both of which he followed with skill and intelligence. The Roman Guide makes mention of him, and that of Florence refers to a Nunziata at S. Mark; and there are others mentioned by Vasari as being in the chapels of that city; one of which is in the Loggia del Grano. The most remarkable of his works is to be seen in Assisi. It is a fresco, and occupies a large façade in one division of the church. It represents the crucifixion of our Saviour, surrounded by bands of soldiers, foot and horse, and a numerous crowd of spectators, all varying in their dress and the expression of their passions. In the sky is a band of angels, whose sympathizing sorrow is vividly depicted. In extent and spirit of design it partakes of the style of Memmi, and in one of the sufferers on the cross he has shewn that he justly appreciated and successfully followed his guide. The colours are well preserved, particularly the blue, which there, and in other parts of the church, presents to our admiring gaze, to use the language of our poets, a heaven of oriental sapphire. Vasari does not appear to have been acquainted with any scholar of Pietro Cavallini, except it be Giovanni da Pistoja; but Pietro, who lived in Rome the greater part of his life, which was extended to a period of eighty-five years, must have contributed his aid in no small degree to the advancement of art, in the capital, as well as in other places. However this may be, in that part of Italy, pictures of his school are still found; or at least memorials of art of the age in which he flourished. We have an Andrea of Velletri, of whom a specimen is preserved in the select collection of the Museo Borgia, with the Virgin surrounded by saints, a common subject at that period in the churches, as I have before observed. It has the name of the painter, with the year 1334, and in execution approaches nearer to the school of Siena than any other. In the year 1321 we find Ugolino Orvietano, Gio. Bonini di Assisi, Lello Perugino, and F. Giacomo da Camerino, noticed by us in another place, all employed in painting in the Cathedral of Orvieto. Mariotti, in his letters, mentions other artists of Perugia, and the memory of a very early painter of Fabriano is preserved by Ascevolini, the historian of that city, who informs us, that in the country church of S. Maria Maddalena, in his time, there was a picture in fresco, by Bocco, executed in 1306. A Francesco Tio da Fabriano, who in 1318 painted the tribune of the Conventuals at Mondaino, is mentioned by Colucci, (tom. xxv. p. 183). This work has perished; but the productions of a successor of his at Fabriano are to be seen in the oratory of S. Antonio Abate, the walls of which remain. Many histories of the saint are there to be found, divided into pictures, in the early style, and
