Afterwards Duke Cosimo, for the marriage of Queen Joanna of Austria, his daughter-in-law, seven years after the death of Baccio, caused the audience-chamber in the Great Hall, begun by Baccio, of which we have spoken above, to be finished; and he chose that the head of this work of completion should be Giorgio Vasari, who has sought with all diligence to put right the many defects that would have been in it if it had been continued and finished after the original design followed in the beginning by Baccio. Thus that imperfect work has now been carried with the help of God to completion, and is enriched on its side faces by the addition of niches and pilasters, and statues set in their places. Moreover, since it was laid out awry and out of square, we have taken pains to make it even in so far as has been possible, and have raised it considerably with a corridor of Tuscan columns at the top; and as for the statue of Leo begun by Baccio, his pupil Vincenzio de' Rossi has finished it. Besides this, that work has been adorned with friezes full of stucco-work, with many figures large and small, and with devices and other ornaments of various kinds, and under the niches and in the partitions of the vaulting have been made many and various designs in stucco and many beautiful inventions in carving; all which things have enriched the work in such a manner, that it has changed its form and has gained not a little in beauty and grace. For whereas, according to the first design, the ceiling of the Hall being twenty-one braccia above the floor, the audience-chamber did not rise higher than eighteen braccia, so that between it and the old ceiling there was a space of only three braccia; now, after our design, the ceiling of the Hall has been raised so much that it has risen twelve braccia above the old ceiling and fifteen above the audience-chamber of Baccio and Giuliano, so that the ceiling is now thirty-three braccia above the floor of the Hall. And it certainly showed great spirit in his Excellency, that he should resolve to cause to be finished in the space of five months for the above-named nuptials the whole of a work of which more than a third still remained to do, although it had taken more than fifteen years to arrive at the condition in which it was at that time; so eager was he to carry it to completion. But it was not only Baccio's work that his Excellency caused to be completely finished, but also all the rest of what Giorgio Vasari had designed; beginning again from the base that runs over the whole of that work, with a border of balusters in the open spaces, which forms a corridor that passes above the work in the Hall, and commands a view on the outer side of the Piazza and on the inner side of the whole Hall. Thus the Princes and other lords will be able to see, without being seen, all the festivals that may be held there, with much pleasure and convenience for themselves, and then to retire to their apartments, passing by the private and public staircases through all the rooms in the Palace. Nevertheless, to many it has caused dissatisfaction that in a work of such beauty and grandeur that structure was not made square, and many would have liked to have it pulled down and then rebuilt true to square. But it has been judged to be better to continue the work in that way, in order not to appear presumptuous and malign towards Baccio, and also because otherwise we would have seemed not to have the power to correct the errors and defects found by us but committed by others.
