"Othello, the Moor of Venice"

Unlike many of Shakespeare's plays, Othello, the Venice of Moor lacks many changes in setting and scenes of action.  The story is presented primarily through dialogue,  more specifically intimate dialogue rarely among more than three characters.  This projects a tone that makes the play seem as if it was acted out in secretive whispers.  Iago knows many of the other characters' secrets and often uses them against them.  For example, in Act III, Iago knows that Cassio approached Desdemona asking her to put in a good word for him with Othello.  Iago urged Cassio to do this.  Yet, he uses Desdemona's praising of Cassio to promote his case that she is cheating on Othello with Cassio.  "Look to your wife. Observe her well with Cassio.  Wear your eye thus, not jealous nor secure.  I would not have your free and noble nature Out of self-bounty be abused" (Act III.iii.198-201).  Iago uses the information he has on other characters in such a way that makes him appear sweet and innocent.  Additionally, Iago is very clever in his ways.  He gives his counterpart characters all the tools so that they may come to the assumption on their own rather than Iago blatantly telling them which only elevates his innocent appearance.
