Michelagnolo, as soon as he had heard that the marble had been given to Baccio, was very much displeased; but, for all the efforts that he made in this matter, he was never able to turn the Pope from his purpose, so completely had he been satisfied by Baccio's model; to which reason were added his promises and boasts, for he boasted that he would surpass the David of Michelagnolo, and he was also assisted by Buoninsegni, who said that Michelagnolo desired everything for himself. Thus was the city deprived of a rare ornament, such as that marble would undoubtedly have been when shaped by the hand of Buonarroti. The above-mentioned model of Baccio is now to be found in the guardaroba of Duke Cosimo, by whom it is held very dear, and by the craftsmen as a rare work.
Baccio was sent to Carrara to see this marble, and the Overseers of the Works of S. Maria del Fiore were commissioned to transport it by water, along the River Arno, as far as Signa. The marble having been conveyed there, within a distance of eight miles from Florence, when they set about removing it from the river in order to transport it by land, the river being too low from Signa to Florence, it fell into the water, and on account of its great size sank so deep into the sand, that the Overseers, with all the contrivances that they used, were not able to drag it out. For which reason, the Pope wishing that the marble should be recovered at all costs, by order of the Wardens of Works Pietro Rosselli, an old builder of great ingenuity, went to work in such a manner that, having diverted the course of the water into another channel and cut away the bank of the river, with levers and windlasses he moved it, dragged it out of the Arno, and brought it to solid ground, for which he was greatly extolled. Tempted by this accident to the marble, certain persons wrote verses, both Tuscan and Latin, ingeniously ridiculing Baccio, who was detested for his loquacity and his evil-speaking against Michelagnolo and all the other craftsmen. One among them took for his verses the following subject, saying that the marble, after having been approved by the genius of Michelagnolo, learning that it was to be mangled by the hands of Baccio, had thrown itself into the river out of despair at such an evil fate.
