Othello then appoints Iago to the lieutenancy. Othello is convinced by this “proof” and vows to kill Desdemona Iago agrees to kill Cassio. Iago alleges that Cassio one night talked in his sleep about making love to Desdemona and that Cassio once wiped his beard with the lost handkerchief. Othello reenters and, now tormented by jealousy, threatens Iago with death unless he provides proof of Desdemona’s infidelity. Emilia picks it up and gives it to Iago, who has often asked for it. As they exit, the handkerchief drops unnoticed by either of them. When Desdemona enters and Othello complains of an aching head, Desdemona offers to bind his head with her handkerchief. He warns Othello against becoming jealous of Desdemona. When she exits, Iago says that Cassio’s avoidance of Othello is suspicious and that Cassio may not be honorable, all the while insinuating that he, Iago, knows more than he is willing to say. Desdemona pleads to Othello on Cassio’s behalf. Lodovico and Graziano enter and hear Cassio’s and Roderigo’s cries. He vows to destroy Othello and Desdemona’s happiness in revenge. Once Othello promotes Cassio to a prominent military role over Iago, Iago feels slighted. Inspired by what he believes to be Iago’s successful vengeance, Othello returns to his bedroom to kill Desdemona. The moor Othello (a military general from North Africa) and Desdemona, the white daughter of a Venetian nobleman, fall in love and marry in secret. Cassio leaves hastily in order to avoid speaking with Othello. Hearing Cassio’s cries of murder, Othello believes that Iago has killed him. Iago knows that Desdemona, the daughter of nobleman Brabantio, has run off to. Iago tells Roderigo that he serves Othello, the Moor who is the armys general, only in order to serve himself. Iago, an ensign in the Venetian army, is bitter about being passed over for lieutenant in favor of Cassio. Desdemona’s interview with Cassio is cut short by the arrival of Othello. Othello begins in the city of Venice, at night.
