Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth. Macbeth has just seen the ghost of Banquo take a seat at Macbeth’s celebratory coronation banquet. Lady Macbeth takes Macbeth aside to find out what is wrong.

Lady Macbeth. [Privately, to MACBETH.] Are you a man?

Macbeth. Ay, and a bold one, that dare look on that
Which might appal the devil.

How does Macbeth’s allusion to the devil help create an eerie mood?

by suggesting that even the devil would be afraid
by explaining that he and Lady Macbeth are the devil
by explaining that Banquo has turned into the devil
by suggesting that the devil is welcome at the banquet
