Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ It is related of Luca Signorelli that he had a son killed in Cortona, a youth of singular beauty in face and person, whom he had tenderly loved. In his deep grief, the father caused his child to be despoiled of his clothing, and, with extraordinary constancy of soul, uttering no complaint and shedding no tear, he painted the portrait of his dead child, to the end that he might still have the power of contemplating, by means of the work of his own hands, that which nature had given him, but which an adverse fortune had taken away. ”
