A work by the same Antonio, likewise, was the principal church of Bergamo, which he built with no less diligence and judgment than he had shown in the above-named hospital. And because he also took delight in writing, the while that these works of his were in progress he wrote a book divided into three parts. In the first he treats of the measurements of all edifices, and of all that is necessary for the purpose of building. In the second he speaks of the methods of building, and of the manner wherein a most beautiful and most convenient city might be laid out. In the third he invents new forms of buildings, mingling the ancient with the modern. The whole work is divided into twenty-four books, illustrated throughout by drawings from his own hand; but, although there is something of the good to be found in it, it is nevertheless mostly ridiculous, and perhaps the most stupid book that was ever written. It was dedicated by him in the year 1464 to the Magnificent Piero di Cosimo de' Medici, and it is now in the collection of the most Illustrious Lord Duke Cosimo. And in truth, since he put himself to so great pains, the book might be commended in some sort, if he had at least made some records of the masters of his day and of their works; but as there are few to be found therein, and those few are scattered throughout the book without method and in the least suitable places, he has toiled only to beggar himself, as the saying goes, and to be thought a man of little judgment for meddling with something that he did not understand.
