SALVATOR ROSA'S OPINION OF HIS OWN WORKS.
While a Roman nobleman was one day endeavoring to drive a hard bargain with Salvator Rosa, he coolly interrupted him, saying that, till the picture was finished, he himself did not know its value; "I never bargain, sir, with my pencil; for it knows not the value of its own labor before the work is finished. When the picture is done, I will let you know what it costs, and you may then take it or not as you please."
