Stefano, Painter of Florence, and Ugolino of Siena.
Stefano, painter of Florence and pupil of Giotto, was so excellent that not only did he surpass all the artists who had studied the arts before him, but he so far surpassed his master himself that he was deservedly considered the best of the painters up to that time, as his works clearly prove. He painted the Madonna in fresco for the Campo Santo at Pisa, and it is somewhat superior in design and colouring to the work of Giotto. In the cloister of S. Spirito at Florence he painted three arches in fresco, in the first of which, containing the Transfiguration with Moses and Elias, he represented the three disciples in fine and striking attitudes. He has formed a fine conception of the dazzling splendour which astonished them, their clothes being in disorder, and falling in new folds, a thing first seen in this picture, as he tried to base his work upon the nude figures, an idea which had not occurred to anyone before, no not even to Giotto himself. Under that arch, in which he made a Christ releasing a demoniac, he drew an edifice in perspective, perfectly, in a style then little known, displaying improved form and more science. He further executed it in the modern manner with great judgment, and displayed such art and such invention and proportion in the columns, doors, windows and cornices, and such different methods from the other masters that it seemed as if he had begun to see some glimpses of the light of the good and perfect manner of the moderns. Among other ingenious things he contrived a very difficult flight of steps, which are shown both in painting and in relief, and possess such design, variety, and invention, and are so useful and convenient that Lorenzo de' Medici, the Magnificent, the elder, made use of the design for the steps outside the palace of Poggio a Caiano, now the principal villa of the Most Illustrious Duke. In the other arch is a representation of Christ saving St Peter from the fury of the waters, so well done that one seems to hear the voice of Peter saying: Domine, salva nos, perimus. This work is considered much finer than the other, because, besides the grace of the draperies, there is a sweetness in the bearing of the heads, a fear of the fortunes of the sea, while the terror of the apostles at various motions and appearances of the water, are represented in very suitable attitudes and with great beauty. And although time has partly destroyed the labour expended by Stefano on this work, one may still discern confusedly that the apostles are defending themselves with spirit from the fury of the winds and waves. This work, which has been highly praised by the moderns, must certainly have appeared a miracle in all Tuscany at the time when it was produced, Stefano then painted in the first cloister of S. Maria Novella a St Thomas Aquinas, next a door, where he also made a crucifix which has since been much damaged by other painters in restoring it. He also left unfinished a chapel in the church, which he began, now much damaged by time. In it may be seen the fall of the angels through the pride of Lucifer, in divers forms. Here it is noteworthy that the foreshortening of the arms, busts, and legs of the figures is much better done than ever before, and this shows us that Stefano began to recognise and had partially overcome the difficulties which stand in the way of the highest excellence, the mastery of which by his successors, by means of unremitting study, has rendered their works so remarkable. For this cause artists have well named him the ape of nature.
