"Satan unavoidably reminds us of Prometheus, and although there are essential differences, we are not made to feel them essential. His very situation as the fearless antagonist of Omnipotence makes him either a fool or a hero, and Milton is far indeed from permitting us to think him a fool. The nobility and greatness of his bearing are brought home to us in some half-dozen of the finest poetic passages in the world."
