Frank Jewett Mather, A history of Italian painting (1923)
“ The vein is rare in Piero, who, aside from his mythological ironies and quite conventional religious pieces, is also a vivacious portraitist as the galleries of New Haven, Conn., the Hague, and London attest.Piero lived on till 1521, surviving both Leonardo and Raphael. The greatest artistic effort of modern times had spent itself before his eyes, and he had mostly been content to be witty. He represents at least a fine scorn of his flimsy training, and remains a consummate type of the artist who lives, like a bear in winter, on his own fat. ”
