Of this Arnolfo we have written the Life, with the greatest brevity that has been possible, for the reason that, although his works do not approach by a great measure the perfection of the things of to-day, he deserves, none the less, to be celebrated with loving memory, having shown amid so great darkness, to those who lived after him, the way to walk to perfection. The portrait of Arnolfo, by the hand of Giotto, is to be seen in S. Croce, beside the principal chapel, at the beginning of the story, where the friars are weeping for the death of S. Francis, in one of two men that are talking together. And the picture of the Church of S. Maria del Fiore--namely, of the outer side with the cupola--by the hand of Simone Sanese, is to be seen in the Chapter-house of S. Maria Novella, copied from the original in wood that Arnolfo made; wherein it is noticeable that he had thought to raise the dome immediately over the walls, at the edge of the first cornice, whereas Filippo di Ser Brunellesco, in order to relieve them of weight and to make it more graceful, added thereto, before he began to raise it, all that height wherein to-day are the round windows; which circumstance would be even clearer than it is, if the little care and diligence of those who have directed the Works of S. Maria del Fiore in the years past had not left the very model that Arnolfo made to go to ruin, and afterwards those of Brunellesco and of the others. FOOTNOTES: [Footnote 6: The braccio is a very variable standard of measurement. As used by Vasari, it may be taken to denote about 23 inches.] [Footnote 7: Vescovado includes both the Cathedral and the Episcopal buildings of Arezzo. Vasari generally uses it to denote the Cathedral.] NICCOLA AND GIOVANNI OF PISA LIFE OF NICCOLA AND GIOVANNI OF PISA, [_NICCOLA PISANO AND GIOVANNI PISANO_], SCULPTORS AND ARCHITECTS Having discoursed of design and of painting in the Life of Cimabue and of architecture in that of Arnolfo di Lapo, in this one concerning Niccola and Giovanni of Pisa we will treat of sculpture, and also of the most important buildings that they made, for the reason that their works in sculpture and in architecture truly deserve to be celebrated, not only as being large and magnificent but also well enough conceived, since both in working marble and in building they swept away in great part that old Greek manner, rude and void of proportion, showing better invention in their stories and giving better attitudes to their figures.
