Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ All the history of the saint in brief, is here depicted, to his decapitation, after which his soul is borne to heaven: the last picture, showing the bones and relics of San Petito, when they are carried from Alexandria [35] to Pisa. The whole work, whether as regards invention or colouring, is the most perfectly executed, the most highly-finished, and the most beautiful of all that Spinello produced; the care with which it was done is made manifest by the fact, that it is so admirably preserved, as to astonish all who behold it by its freshness. ”
