This one is another of my most favorite from him. Brilliant romantic--someone who definitely have meaning in his paintings. This piece is actually sarcasm; poking fun at hysteria and 'caprices'/ignorance of his day (in fact he had a famous sketch entitled 'Caprichos'--which poked fun at superstition). It's his way of saying "the devil is none other than your tyrant and fear itself".
