Pope Leo had allotted the work of the ornamentation in marble that surrounds the Chamber of Our Lady at Loreto, with the statues and scenes, to Maestro Andrea Contucci of Monte Sansovino, who had already executed some of these with great credit to himself, and was then engaged on others. Now at this time Baccio took to Rome, for the Pope, a very beautiful model of a nude David who was holding Goliath under him and was cutting off his head; which model he intended to execute in bronze or in marble for that very spot in the court of the house of the Medici in Florence where there once stood the David of Donato, which, at the spoiling of the Medici Palace, was taken to the Palace that then belonged to the Signori. The Pope, having praised Baccio, but not thinking that the time had come to execute the David, sent him to Loreto to Maestro Andrea, to the end that Andrea might give him one of those scenes to do. Having arrived in Loreto, he was received lovingly by Maestro Andrea and shown much kindness, both on account of his fame and because the Pope had recommended him, and a piece of marble was assigned to him from which he should carve the Nativity of Our Lady. Baccio, after making the model, began the work; but, being a person who was not able to endure a colleague or an equal, and had little praise for the works of others, he also began to speak hardly before the other sculptors who were there of the works of Maestro Andrea, saying that he had no design, and he said the same of the others, insomuch that in a short time he made himself disliked by them all. Whereupon, all that Baccio had said of Maestro Andrea having come to his ears, he, like a wise man, answered him lovingly, saying that works are done with the hands and not with the tongue, that good design is to be looked for not in drawings but in the perfection of the work finished in stone, and, finally, that in future Baccio should speak of him in a different tone. But Baccio answering him arrogantly with many abusive words, Maestro Andrea could endure no more, and rushed upon him in order to kill him; but Bandinelli was torn away from him by some who intervened between them. Being therefore forced to depart from Loreto, Baccio had his scene carried to Ancona; but he grew weary of it, although it was near completion, and he went away leaving it unfinished. This work was finished afterwards by Raffaello da Montelupo, and placed together with the others of Maestro Andrea; but it is by no means equal to them in excellence, although even so it is worthy of praise.
