In Act III, Scene ii, Macbeth says that he and his wife must make their faces vizards, or masks, to their hearts. The Tragedy of Macbeth contains many instances in which the characters mask their thoughts, feelings, or desires. Write an essay about the theme of “masks”—betrayal, falsehood, and concealment—in Act III of the play. Which characters use them? What do they conceal and why? Are the masks necessarily evil? Use examples from the text to illustrate your points.
