He gave his attention to colouring in oils, having seen some works of Leonardo's, executed with that gradation of colour, and finished with that extraordinary diligence, which Leonardo used to employ when he wished to display his art. And so Piero, being pleased with his method, sought to imitate it, although he was afterwards very distant from Leonardo, and worlds away from any other manner. It may be said, in truth, that he changed his manner almost for every work that he executed. If Piero had not been so solitary, and had taken more care of himself in his way of living than he did, he would have made known the greatness of his intellect in such a way that he would have been revered, whereas, by reason of his uncouth ways, he was rather held to be a madman, although in the end he did no harm save to himself alone, while his works were beneficial and useful to his art. For which reason every good intellect and every excellent craftsman should always be taught, from such an example, to keep his eyes on the end of life. Nor will I refrain from saying that Piero, in his youth, being fanciful and extravagant in invention, was much employed for the masquerades that are held during the Carnival; and he became very dear to the young noblemen of Florence, having improved their festivals much in invention, adornment, grandeur, and pomp. As to that kind of pastime, it is said that he was one of the first to contrive to marshal them in the form of triumphal processions; at least, he improved them greatly, by accompanying the invention of the story represented, not only with music and with words suited to the subject, but also with a train of incredible pomp, formed of men on foot and on horseback, with habits and ornaments in keeping with the story; which produced a very rich and beautiful effect, and had in it something both grand and ingenious. And it was certainly a very beautiful thing to see, by night, twenty-five or thirty pairs of horses, most richly caparisoned, with their riders in costume, according to the subject of the invention, and six or eight grooms to each rider, with torches in their hands, and all clothed in one and the same livery, sometimes more than four hundred in number; and then the chariot, or triumphal car, covered with ornaments, trophies, and most bizarre things of fancy; altogether, a thing which makes men's intellects more subtle, and gives great pleasure and satisfaction to the people.
