a summary of act 2, scene i

A terrible storm has struck Cyprus, just as the Turks were about to approach. This might mean that the Turkish attack will not happen; but it also bodes badly for Othello's ship. A messenger enters, and confirms that the Turkish fleet was broken apart by the storm, and that Cassio has arrived, though Othello is still at sea. They spot a ship coming forth; but Iago, Desdemona, and Emilia are on it, not Othello. Cassio greets them all, especially praising Desdemona; somehow, Iago and Desdemona enter into an argument about what women are, and Iago shows how little praise he believes women deserve. Othello arrives at last, and is very glad to see his wife arrived, much earlier than expected; he and Desdemona make public signs of their love, and then depart. Iago speaks to Roderigo, convincing him that Desdemona will stray from Othello, as she has already done with Cassio. He convinces Roderigo to attack Cassio that night, as he plans to visit mischief on both Othello and Cassio.
