For other uses, see Iago (disambiguation). Iago is a fictional character in Shakespeare's Othello (c. 1601â1604). Iago is the play's main antagonist, and Othello's standard bearer. He is the husband of Emilia, who is in turn the attendant of Othello's wife Desdemona. Iago hates Othello and devises a plan to destroy him by making him believe that his wife is having an affair with his lieutenant, Michael Cassio.
Later, he claims to suspect that Othello is having an affair with his (Iago's) wife (Emilia): IAGO I hate the Moor, And it is thought abroad, that 'twixt my sheets'Has done my office. I know not if 't be true, But I, for mere suspicion in that kind, Will do as if for surety.oet Samuel Taylor Coleridge calls Iago a being next to the devil, only not quite the devil and goes on to call Iago's behavior motiveless malignity.. If we agree that Iago has no real motives for hurting Othello, we could also argue that Iago's character is a kind of Vice figure.
