Iago tells Rodrigo to "poison [Brabantio's] pleasure... to praise [Desdemona's] parents, and although he may live in a fertile climate, the torment with flies” (1.1). This sensory imagery shows how Iago thinks this news will affect Desdemona's father. He also says “with as little web as that, I could trap a big fly like Cassio” (2.1). Through this comparison, Shakespeare creates the image of Iago as a spider and Cassio as a fly who is about to become prey to the spider. By stating that Cassio is a big fly, Iago shows how great he is. Othello cries “farewell to the neighboring steed and the shrill trumpet, to the drum that vibrates the spirits, to the piercing fife, to the royal banner and to all quality” (3.3). In describing some of the things related to war and the military, Shakespeare emphasizes that Othello can no longer worry about these things, because hurting Cassio and Desdemona is his main concern.
