I have written the life of Arnolfo with the greatest possible brevity because, although his works do not nearly approach the perfection of those of the present time, yet he none the less deserves to be remembered with affection, since, in the midst of so great darkness, he pointed out the road to perfection to those who came after him. The portrait of Arnolfo, by the hand of Giotto, may be seen in S. Croce, next to the principal chapel, where the friars are mourning the death of St Francis. He is represented in the foreground as one of the two men who are talking together. A representation of the exterior of the church of S. Maria del Fiore, with the dome, by the hand of Simon of Siena, may be seen in the chapter-house of S. Maria Novella. It was taken from the actual model of wood which Arnolfo made. From this representation it is clear that Arnolfo proposed to begin to vault his space, starting immediately above the first cornice, whilst Filippo di Ser Brunellesco, desiring to lighten the weight and make the appearance of the structure more graceful, added above this the whole of the space which contains the round windows before he began his vaulting. This matter would be even more obvious than it is had not the negligence and carelessness of those who had charge of the works of S. Maria del Fiore in past years allowed Arnolfo's own model, as well as those of Brunellesco and others, to be lost. Niccola and Giovanni Pisani, Sculptors and Architects. Having discussed the arts of design and painting in dealing with Cimabue, and that of architecture in the life of Arnolfo Lapo, we now propose to treat of sculpture, and of the very important architectural works of Niccola and Giovanni Pisani. Their achievements in both sculpture and architecture are alike remarkable for the manner in which they have been conceived as well as for the style in which they are executed, since to a great extent they emancipated themselves from the clumsy and ill-proportioned Byzantine style in both arts, showing more originality in the treatment of their subjects and arranging their figures in better postures. Niccola Pisani was originally associated with some Greek sculptors who were engaged upon the figures and other ornaments in relief for the Duomo at Pisa and the church of San Giovanni there. Among the spoils brought home by the Pisan fleet was a very fine sarcophagus on which was an admirable representation of the chase of Meleager, hunting the Calydonian boar. Both the nude and the draped figures of this composition are executed with much skill, while the design is perfect. This sarcophagus, on account of its beauty, was afterwards placed by the Pisans in the facade of the Duomo opposite S, Rocco, against the principal door on that side. It originally served as a tombstone for the mother of the Countess Matilda, if we may credit the inscription cut in the marble:
