"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 it? 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
1855
The Faultless painter
