Next, having been appointed on account of his abilities, and because he was much beloved by the citizens, as architect to S. Maria del Fiore, Baccio gave the design for constructing the gallery that encircles the cupola. This part of the work Filippo Brunelleschi, being overtaken by death, had not been able to execute; and although he had made designs even for this, they had been lost or destroyed through the negligence of those in charge of the building. Baccio, then, having made the design and model for this gallery, carried into execution all the part that is to be seen facing the Canto de' Bischeri. But Michelagnolo Buonarroti, on his return from Rome, perceiving that in carrying out this work they were cutting away the toothings that Filippo Brunelleschi, not without a purpose, had left projecting, made such a clamour that the work was stopped; saying that it seemed to him that Baccio had made a cage for crickets, that a pile so vast required something grander and executed with more design, art, and grace than appeared to him to be displayed by Baccio's design, and that he himself would show how it should be done. Michelagnolo having therefore made a model, the matter was disputed at great length before Cardinal Giulio de' Medici by many craftsmen and competent citizens; and in the end neither the one model nor the other was carried into execution. Baccio's design was censured in many respects, not that it was not a well-proportioned work of its kind, but because it was too insignificant in comparison with the size of the structure; and for these reasons that gallery has never been brought to completion. Baccio afterwards gave his attention to executing the pavement of S. Maria del Fiore, and to his other buildings, which were not a few, for he had under his particular charge all the principal monasteries and convents of Florence, and many houses of citizens, both within and without the city. Finally, when near the age of eighty-three, but still of good and sound judgment, he passed to a better life in 1543, leaving three sons, Giuliano, Filippo, and Domenico, who had him buried in S. Lorenzo.
