In William Shakespeare’s Othello, the power of jealousy dominates the play; at first, it’s Iago who is stricken with jealousy, when Othello appoints Cassio as his new lieutenant. Iago states, “And I, of whom his eyes had seen the proof at Rhodes, at Cyprus, and on other grounds…must be beleed and calmed by debitor and creditor,”(I.i.29-32) after finding out he will be an ancient instead of a lieutenant.

He vows to retaliate against Othello by proceeding to manipulate his friends, enemies, and family into doing his bidding without any of them realizing. Iago implants his first evil thought into Othello’s mind about Desdemona, Othello’s wife. Iago questions Othello about the relationship between Cassio and Desdemona, to mess with his mind.

After a statement like this Othello, now, wanted to know why Iago was asking and what he is thinking. He goes on to tell Othello that he believes Cassio is sleeping with Othello’s wife. Now
