He left behind him both sons and daughters, who were the heirs to his many possessions in lands, houses, and money, which he bequeathed to them; and to the world he left the works in sculpture described by us, and designs in great numbers, which are in the possession of his family, and in our book there are some executed with the pen and with chalk, than which it is certain that nothing better could be done. The marble for the giant was left more in dispute than ever, because Benvenuto was always about the Duke, and wished, in virtue of a little model that he had made, that the Duke should give it to him. On the other hand, Ammanati, being a sculptor of marbles and more experienced in such works than Benvenuto, considered for many reasons that this work belonged to him. Now it happened that Giorgio Vasari had to go to Rome with the Cardinal, the son of the Duke, when he went to receive his hat, and Ammanati gave to Vasari a little model of wax showing the shape in which he desired to carve that figure from the marble, and a piece of wood reproducing the exact proportions--the length, breadth, thickness, and inclination from the straight--of the marble, to the end that Giorgio might show them in Rome to Michelagnolo Buonarroti and persuade him to declare his opinion in the matter, and so move the Duke to give him the marble. All this Giorgio did most willingly, and it was the reason that the Duke gave orders that an arch should be partitioned off in the Loggia of the Piazza, and that Ammanati should make a great model as large as the giant was to be. Having heard this. Benvenuto rode in a great fury to Pisa, where the Duke was, and said to him that he could not suffer that his genius should be trampled underfoot by one who was inferior to himself, and that he desired to make a great model in competition with Ammanati, in the same place; and the Duke, wishing to pacify him, granted him leave to have another arch of the Loggia partitioned off, and caused to be given to him materials for making, as he desired, a large model in competition with Ammanati.
