indeed, that this tower has nothing else good in it, neither manner, nor ornament, nor, in short, anything that might be worthy of much praise. It was finished under Anastasius IV and Adrian IV, Pontiffs, in the year 1154. In architecture, likewise, Buono made the Church of S. Andrea in Pistoia, and in sculpture he made an architrave of marble that is over the door, full of figures made in the manner of the Goths, on which architrave his name is carved, with the date when this work was made by him, which was the year 1166. Next, being summoned to Florence, he gave the design for enlarging, as was done, the Church of S. Maria Maggiore, which was then without the city, and held in great veneration for the reason that Pope Pelagius had consecrated it many years before, and because, as to size and manner, it was a very fair body of a church. Being then summoned by the Aretines to their city, Buono built the old habitation of the Lords of Arezzo, namely, a palace in the manner of the Goths, and beside it a bell-tower. This edifice, which for that manner was good enough, was thrown to the ground, because it was opposite and very near to the fortress of that city, in the year 1533. Afterwards, the art making some little improvement through the works of one Guglielmo, German (I believe) in origin, there were built certain edifices of the greatest cost and in a slightly better manner; for this Guglielmo, so it is said, in the year 1174, together with Bonanno, a sculptor, founded in Pisa the Campanile of the Duomo, where there are certain words carved that say: A.D. MCLXXIV, CAMPANILE HOC FUIT FUNDATUM, MENSE AUG. But these two architects not having much practice of founding in Pisa and therefore not supporting the platform with piles, as they ought, before they had gone halfway with that building it inclined to one side and bent over to the weakest part, in a manner that the said campanile leans six and a half braccia[6] out of the straight, according as the foundation sank on this side; and although in the lower part this is not much, up above it shows clear enough to make men stand fast in a marvel how it can be that it has not fallen down and has not thrown out cracks. The reason is that this edifice is round both without and within and built in the shape of a hollow well, and bound together with the stones in a manner that it is well-nigh impossible that it should fall; and it is assisted, above all, by the foundations, which have an outwork three braccia wide outside the tower, made, as it is seen, after the sinking of the campanile, in order to support it. I am convinced that if it had been square it would not have been standing to-day, for the reason that the corner-stones of the square sides, as is often seen to happen, would have forced them out in a manner that it would have fallen down. And if the Garisenda, a tower in Bologna, although square, leans and does not fall, that comes to pass because it
