Listen to this one as you watch this one.
"I, painting from myself and to myself,
Know what I do, am unmoved by men's blame
Or their praise either. Somebody remarks
Morello's outline there is wrongly traced,
His hue mistaken; what of that ? or else,
Rightly traced and well ordered; what of that ?
Speak as they please, what does the mountain care ?
Ah, but a man's reach should exceed his grasp,
Or what's a heaven for?" (Robert Browning, "Andrea Del Sarto", lines 90-98, 1855.)
