Iago advises Othello, "She did deceive her father, marrying you; and when she seem'd to shake and fear your looks, she loved them most. She that, so young, could give out such a seeming, to steal her father's eyes up close as oak- his thought 'twas witchcraft..." (III.3.40-43) and then convinces him "...I may fear her will, recoiling to her better judgment, may fall to match you with her country forms and happily repent" (III.3.51-52). Othello is obviously convinced by this, thinking, "And yet, how nature erring from itself,--" (III.3.50)
