Othello, the Moor of Venice
(Auto-generated)

I ran it through, even from my boyish days To the very moment that he bade me tell it: Wherein I spake of most disastrous chances, Of moving accidents by flood and field; Of hair-breadth scapes i' the imminent deadly breach; Of being taken by the insolent foe, And sold to slavery; of my redemption thence, And portance in my travels' history: Wherein of antres vast and deserts idle, Rough quarries, rocks, and hills whose heads touch heaven, It was my hint to speak,—such was the process; And of the Cannibals that each other eat, The Anthropophagi, and men whose heads Do grow beneath their shoulders.†
Scene 1.3

breach = break or penetrate
