Iago and Roderigo are talking, and Iago
tells Cassio that Othello has passed him over for a promotion and Cassio, another soldier, has received
it. Iago decides to tell Brabantio, a Venice senator, that his daughter Desdemona has eloped with
Othello. Roderigo eagerly joins him, having been turned down as a suitor by Desdemona. They
wake Brabantio up in the middle of the night, and, very angrily, he forms an armed mob of family and
friends to find Othello and rescue his daughter.
