O perjured woman! thou dost stone my heart,
And makest me call what I intend to do
A murder, which I thought a sacrifice.
– William Shakespeare
Othello, Act 5, Scene 2. Othello accuses Desdemona of perjury after she denies giving her handkerchief to Cassio, explaining that Cassio must have found it. Othello prefers to believe that she was unfaithful because he saw the handkerchief in Cassio’s hand. He dismisses his wife’s plea to send for Cassio to find out the truth. The blinded Othello proceeds to act as judge, jury and executioner. He believes that he is not a murderer but a deliverer of justice. Metaphors play a big part in the play, with Othello using one to say that his wife has turned his heart to stone.
