Othello- Minor Characters

Othello, the Moor of Venice
William Shakespeare

Though Iago is truthfully the main focus of the play, and Othello is obviously important, hence the title, the minor characters also play an important role. Roderigo is introduced as, basically, Iago's puppet. Desdemona is Brabantio's daughter and Othello's wife, and is involved with other people, including Iago's wife Emilia.
Roderigo does whatever Iago says, even selling his land for money that Iago told him to get. Roderigo follows Iago's advice, even when Iago is only using him.
Iago and Desdemona have a conversation about women that characterizes both of them. Iago is misogynistic and critical, and Desdemona is out spoken and clever. Desdemona might be a force to be reckoned with in Iago's unfolding plans.
One character that was specifically characterized in Acts II and III was Iago's wife, Emilia. Iago says she is nagging and loud. But, Emilia barely even spoke in Act II. But soon, Emilia is characterized by her actions she takes in reference to Desdemona's cherished handkerchief. "Emilia: I am glad I have found this napkin. This was her first remembrance from the Moor. My wayward husband hath a hundred times wooed me to steal it..." (III.iii.291-294) Even though her husband isn't very nice to her, she still obeys his wishes, even though they might hurt her friend Desdemona. I am interested to see how the minor characters continue to add to the complexity of the work, and also how Iago will find a way to use these minor characters to his benefit.
