Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ I am of opinion that Raffaello would have produced more and better performances in art, if he had undertaken works of more importance, as he very well might have done; but he was too gentle and diffident; he had a great aversion to all conflict, and contenting himself with the little which fate had provided for him, he suffered many opportunities for securing works by wbicb he might have distinguished himself, to escape his hands. Raffaello drew very skilfully, and had a much clearer intelligence of all things pertaining to art, than was evinced by his father, Baccio da Monte Lupo. ”
