Alberti praises the painters of Florence
I used to marvel and at the same time to grieve that so many excellent and superior arts and sciences from our most vigorous antique past could now seem lacking and almost wholly lost. We know from [remaining] works and through references to them that they were once widespread. Painters, sculptors, architects, musicians, geometricians, rhetoricians, seers and similar noble and amazing intellects are very rarely found today and there are few to praise them. Thus I believed, as many said, that Nature, the mistress of things, had grown old and tired. She no longer produced either geniuses or giants which in her more youthful and more glorious days she had produced so marvelously and abundantly.
Since then, I have been brought back here [to Florence]—from the long exile in which we Alberti have grown old—into this our city, adorned above all others. I have come to understand that in many men, but especially in you, Filippo, and in our close friend Donato the sculptor and in others like Nencio, Luca and Masaccio, there is a genius for [accomplishing] every praiseworthy thing. For this they should not be slighted in favor of anyone famous in antiquity in these arts. Therefore, I believe the power of acquiring wide fame in any art or science lies in our industry and diligence more than in the times or in the gifts of nature. It must be admitted that it was less difficult for the Ancients—because they had models to imitate and from which they could learn—to come to a knowledge of those supreme arts which today are most difficult for us. Our fame ought to be much greater, then, if we discover unheard-of and never-before-seen arts and sciences without teachers or without any model whatsoever. Who could ever be hard or envious enough to fail to praise Pippo the architect on seeing here such a large structure, rising above the skies, ample to cover with its shadow all the Tuscan people, and constructed without the aid of centering or great quantity of wood? Since this work seems impossible of execution in our time, if I judge rightly, it was probably unknown and unthought of among the Ancients. But there will be other places, Filippo, to tell of your fame, of the virtues of our Donato, and of the others who are most pleasing to me by their deeds.
