Under the influence of the liquor Cassio resents the taunts of Roderigo, instigated by Iago. Montano tries to quiet him. Cassio draws. There follows the fight in which Montano is wounded. The tumult, swelled by alarums and the ringing of bells, brings Othello with Desdemona to the scene. Cassio is dismissed from the Moor's service. Iago has scored his first triumph.
The people disperse. Quiet settles upon the scene. Othello and Desdemona are alone. The act closes with their love duet, which Desdemona begins with "Quando narravi" (When thou dids't speak).

Act II. A hall on the ground floor of the castle. Iago, planning to make Othello jealous of Desdemona, counsels Cassio to induce the Moor's wife to plead for his reinstatement. Cassio goes into a large garden at the back. Iago sings his famous "Credo in un Dio che m'ha creato" (I believe in a God, who has created me in his image). This is justly regarded as a masterpiece of invective. It does not appear in Shakespeare, so that the lines are as original with Boïto as the music is with Verdi. Trumpets, employed in what may be termed a declamatory manner, are conspicuous in the accompaniment.
Iago, seeing Othello approach, leans against a column and looks fixedly in the direction of Desdemona and Cassio, exclaiming, as Othello enters, "I like not that!" As in the corresponding scene in the play, this leads up to the questioning of him by Othello and to Iago's crafty answers, which not only apply the match to, but also fan the flame of Othello's jealousy, as he watches his wife with Cassio.
Children, women, and Cypriot and Albanian sailors now are seen with Desdemona. They bring her flowers and other gifts. Accompanying themselves on the cornemuse, and small harps, they sing a mandolinata, "Dove guardi splendono" (Wheresoe'er thy glances fall). This is followed by a graceful chorus for the sailors, who bring shells and corals.
The scene and Desdemona's beauty deeply move the Moor. He cannot believe her other than innocent. But, unwittingly, she plays into Iago's hand. For her first words on joining Othello are a plea for Cassio. All the Moor's jealousy is re-aroused. When she would apply her handkerchief to his heated brow, he tears it from her hand, and throws it to the ground. Emilia picks it up, but Iago takes it from her. The scene is brought to a close by a quartet for Desdemona, Othello, Iago, and Emilia.
Othello and Iago are left together again. Othello voices the grief that shakes his whole being, in what Mr. Upton happily describes as "a pathetic but stirring melody." In it he bids farewell, not only to love and trust, but to the glories of war and battle. The trumpet is effectively employed in the accompaniment to this outburst of grief, which begins, "Addio sante memorie" (Farewell, O sacred memories).
