Iago offers to help the young Venetian gentleman Roderigo in his seduction of Otello's wife, Desdemona – Iago envies Otello his success and longs to destroy the Moor (Iago, Roderigo: Roderigo, ebben che pensi? / "Well, Roderigo, what are you thinking?"). Among his grievances, Iago is outraged that Otello has appointed Cassio to be the captain of the navy, a position that Iago hoped to have. The people of Cyprus celebrate the safe return of Otello and his men by lighting a bonfire and drinking (Chorus: Fuoco di gioia!/ "Fire of joy").
