they may appear rather crude than otherwise to modern eyes, yet they serve to show to what an extent the art of design profited by his labours. Arnolfo di Lapo, Florentine Architect. In the preface to these lives I have spoken of some edifices in the old but not antique style, and I was silent respecting the names of the artists who executed the work, because I did not know them. In the introduction to the present life I propose to mention some other buildings made in Arnolfo's time, or shortly before, the authors of which are equally unknown, and then to speak of those which were erected during his lifetime, the architects of which are known, either because they may be recognised through the style of the buildings, or because there is some notice of them in the writings and memorials left by them in the works done. This will not be beside the point, for although the buildings are neither beautiful nor in good style, but only very large and magnificent, yet they are none the less worthy of some consideration. In the time of Lapo, and of Arnolfo his son, many buildings of importance were erected in Italy and outside, of which I have not been able to find the names of the architects. Among these are the abbey of Monreale in Sicily, the Piscopio of Naples, the Certosa of Pavia, the Duomo of Milan, S. Pietro and S. Petrodio of Bologna, and many others, which may be seen in all parts of Italy, erected at incredible cost. I have seen and examined all these buildings, as well as many sculptures of these times, particularly at Ravenna, but I have never found any memorial of the masters, and frequently not even the date when they were erected, so that I cannot but marvel at the simplicity and indifference to fame exhibited by the men of that age. But to return to our subject. After the buildings just enumerated there arose some persons of a more exalted temper, who, if they did not succeed in lighting upon the good, at least made the attempt.
