such a manner that, where there was formerly water, many tracts of land and villas have sprung up, to the great benefit of the city of Venice. Wherefore it is the opinion of many persons, and in particular of the Magnificent Messer Luigi Cornaro, a Venetian gentleman of ripe wisdom gained both by learning and by long experience, that, if it had not been for the warning of Fra Giocondo, all the silting up that took place in the lagoons of Chioggia would have happened, and perhaps on a greater scale, in those of Venice, inflicting incredible damage and almost ruin on that city. The same Messer Luigi, who was very much the friend of Fra Giocondo, as he is and always has been of all men of talent, declares that his native city of Venice owes an eternal debt of gratitude for this to the memory of Fra Giocondo, who on this account, he says, might reasonably be called the second founder of Venice; and that he almost deserves more praise for having preserved by that expedient the grandeur and nobility of that marvellous and puissant city, than do those who built it at the beginning in such a weak and ill-considered fashion, seeing that the benefit received from him will be to all eternity, as it has been hitherto, of incalculable utility and advantage to Venice. Not many years after Fra Giocondo had executed this divine work, the Venetians suffered a great loss in the burning of the Rialto, the place in which are the magazines of their most precious merchandise--the treasure, as it were, of that city. This happened at the very time when that Republic had been reduced by long-continued wars and by the loss of the greater part, or rather almost the whole, of her dominions on the mainland to a desperate condition; and the Signori then governing were full of doubt and hesitation as to what they should do. However, the rebuilding of that place being a matter of the greatest importance, they resolved that it should be reconstructed at all costs. And wishing to give it all possible grandeur, in keeping with the greatness and magnificence of that Republic, and having already recognized the talent of Fra Giocondo and his great ability in architecture, they gave him the commission to make a design for that structure; whereupon he drew one in the following manner. He proposed to occupy all the space that lies between the Canale delle Beccherie,[1] in the Rialto, and the Rio del Fondaco delle Farine,[2] taking as much ground between one canal and the other as would make a perfect square--that is, the length of the sides of this fabric was to be as great as the space which one covers at the present day in walking from the debouchure of one of those canals into the Grand Canal to that of the other. He intended, also, that the same two canals should debouch on the other side into a common canal, which was to run from the one to the other, so that the fabric might be left entirely surrounded by water, having the Grand Canal on one side, the
