As far back as the time of Leo X there had been quarried at Carrara, together with the marbles for the facade of S. Lorenzo in Florence, another block of marble nine braccia and a half high and five braccia wide at the foot. With this block of marble Michelagnolo Buonarroti had thought of making a giant in the person of Hercules slaying Cacus, intending to place it in the Piazza beside the colossal figure of David formerly made by him, since both the one and the other, David and Hercules, were emblems of the Palace. He had made several designs and various models for it, and had sought to gain the favour of Pope Leo and of Cardinal Giulio de' Medici, saying that the David had many defects caused by the sculptor Maestro Andrea, who had first blocked it out and spoiled it. But by reason of the death of Leo the facade of S. Lorenzo was for a time abandoned, and also this block of marble. Now afterwards, Pope Clement having conceived a desire to avail himself of Michelagnolo for the tombs of the heroes of the house of Medici, which he wished to have constructed in the Sacristy of S. Lorenzo, it became once more necessary to quarry marbles; and the head of these works, keeping the accounts of the expenses, was Domenico Buoninsegni. This man tried to tempt Michelagnolo to make a secret partnership with him in the matter of the stone-work for the facade of S. Lorenzo; but Michelagnolo refused, not consenting that his genius should be employed in defrauding the Pope, and Domenico conceived such hatred against him that he went about ever afterwards opposing his undertakings, in order to annoy and humiliate him, but this he did covertly. He thus contrived to have the facade discontinued and the sacristy pushed forward, which two works, he said, were enough to keep Michelagnolo occupied for many years. And as for the marble for the making of the giant, he urged the Pope that it should be given to Baccio, who at that time had nothing to do; saying that through the emulation of two men so eminent his Holiness would be served better and with more diligence and promptitude, rivalry stimulating both the one and the other in his work. The counsel of Domenico pleased the Pope, and he acted in accordance with it. Baccio, having obtained the marble, made a great model in wax, which was a Hercules who, having fixed the head of Cacus between two stones with one knee, was constraining him with great force with the left arm, holding him crouching under his legs in a distorted attitude, wherein Cacus revealed his suffering and the strain of the weight of Hercules upon him, which was rending asunder every least muscle in his whole body. Hercules, likewise, with his head bent down close against his enemy, grinding and gnashing his teeth, was raising the right arm and with great vehemence giving him another blow with his club, in order to dash his head to pieces.
