surpass him, in these others; and he devoted himself, therefore, not to imitating the manner of that master, but to the attainment of a catholic excellence in the other fields of art that have been described. And if the same had been done by many craftsmen of our own age, who, having determined to pursue the study of Michelagnolo's works alone, have failed to imitate him and have not been able to reach his extraordinary perfection, they would not have laboured in vain nor acquired a manner so hard, so full of difficulty, wanting in beauty and colouring, and poor in invention, but would have been able, by aiming at catholicity and at imitation in the other fields of art, to render service both to themselves and to the world. Raffaello, then, having made this resolution, and having recognized that Fra Bartolommeo di San Marco had a passing good method of painting, well-grounded draughtsmanship, and a pleasing manner of colouring, although at times, in order to obtain stronger relief, he made too much use of darks, took from him what appeared to him to suit his need and his fancy--namely, a middle course, both in drawing and in colouring; and mingling with that method certain others selected from the best work of other masters, out of many manners he made one, which was looked upon ever afterwards as his own, and which was and always will be vastly esteemed by all craftsmen. This was then seen perfected in the Sibyls and Prophets of the work that he executed, as has been related, in S. Maria della Pace; in the carrying out of which work he was greatly assisted by having seen the paintings of Michelagnolo in the Chapel of the Pope. And if Raffaello had remained content with this same manner, and had not sought to give it more grandeur and variety in order to prove that he had as good a knowledge of the nude as Michelagnolo, he would not have lost a part of the good name that he had acquired; but the nudes that he made in that apartment of the Borgia Tower where there is the Burning of the Borgo, although they are fine, are not in every way excellent. In like manner, those that were painted likewise by him on the ceiling of the Palace of Agostino Chigi in the Trastevere did not give complete satisfaction, for they are wanting in that grace and sweetness which were peculiar to Raffaello; the reason of which, in great part, was the circumstance that he had them coloured by others after his design. However, repenting of this error, like a man of judgment, he resolved afterwards to execute by himself, without assistance from others, the panel-picture of the Transfiguration of Christ that is in S. Pietro a Montorio, wherein are all those qualities which, as has already been described, are looked for and required in a good picture. And if he had not employed in this work, as it were from caprice, printer's smoke-black, the nature of which, as has been remarked many times, is to become ever darker with time, to the
