Pope Paul had made a beginning with the fortifying of the Borgo, and had summoned many gentlemen, together with Antonio da San Gallo, to a conference; but he wished that Michelagnolo also should have a part in this, knowing that the fortifications about the hill of S. Miniato in Florence had been constructed under his direction. After much discussion, Michelagnolo was asked what he thought; and he, having opinions contrary to San Gallo and many others, declared them freely. Whereupon San Gallo said to him that his arts were sculpture and painting, and not fortification. Michelagnolo replied that of sculpture and painting he knew little, but of fortification, what with the thought that he had devoted to it for a long time, and his experience in what he had done, it appeared to him that he knew more than either Antonio or any of his family; showing him in the presence of the company that he had made many errors in that art. Words rising high on either side, the Pope had to command silence; but no long time passed before Michelagnolo brought a design for all the fortifications of the Borgo, which laid open the way for all that has since been ordained and executed; and this was the reason that the great gate of S. Spirito, which was approaching completion under the direction of San Gallo, was left unfinished. [Illustration: PIETÀ (_After =Michelagnolo=. Florence: Duomo_) _Alinari_] The spirit and genius of Michelagnolo could not rest without doing something; and, since he was not able to paint, he set to work on a piece of marble, intending to carve from it four figures in the round and larger than life, including a Dead Christ, for his own delight and to pass the time, and because, as he used to say, the exercise of the hammer kept him healthy in body. This Christ, taken down from the Cross, is supported by Our Lady, by Nicodemus, who bends down and assists her, planted firmly on his feet in a forceful attitude, and by one of the Maries, who also gives her aid, perceiving that the Mother, overcome by grief, is failing in strength and not able to uphold Him. Nor is there anywhere to be seen a dead form equal to that of Christ, who, sinking with the limbs hanging limp, lies in an attitude wholly different, not only from that of any other work by Michelagnolo, but from that of any other figure that was ever made. A laborious work is this, a rare achievement in a single stone, and truly divine; but, as will be related hereafter, it remained unfinished, and suffered many misfortunes, although Michelagnolo had intended that it should serve to adorn his own tomb, at the foot of that altar where he thought to place it.
