William Michael Rossetti

“ His most extensive extant series of frescoes is in the choir of S. Francesco in Arezzo,—the “History of the Cross,” beginning with legendary subjects of the death and burial of Adam, and going on to the entry of Heraclius into Jerusalem after the overthrow of Chosroes. ”

“ Piero appears to have been much in his native town of Borgo San Sepolcro from about 1445, and more especially after 1454, when he finished the series in Arezzo. He grew rich there, and there he died, and in October 1492 was buried.
Two statements made by Vasari regarding “Piero della Francesca” are open to much controversy. He says that Piero became blind at the age of sixty, which cannot be true, as he continued painting some years later ”

“ He had more science than either Paolo Uccello or Mantegna, both of them his contemporaries, the former older and the latter younger. Skilful in linear perspective, he fixed rectangular planes in perfect order and measured them, and thus got his figures in true proportional height. ”
