No, perhaps not so much a fine quote, but more of a fine passage; illustrating the necessity of thinking critically whenever we experience a work of art . . .
“I’ll lay a bet,” said Sancho, “that before long there won’t be a tavern, roadside inn, hostelry, or barber’s shop where the story of our doings won’t be painted up; but I’d like it painted by the hand of a better painter than painted these.”
“Thou art right, Sancho,” said Don Quixote, “for this painter is like Orbaneja, a painter there was at Ubeda, who when they asked him what he was painting, used to say, ‘Whatever it may turn out; and if he chanced to paint a cock he would write under it, ‘This is a cock,’ for fear they might think it was a fox.
– Miguel de Cervantes, from Don Quixote
True Dat. We must always remain vigilant against artists who mangle cocks into foxes . . .
