Allusion (2)

“Her face looked to me as if it were all disturbed by fiery air, like the faces I had seen rise out of the Witches’ cauldron.” (201)

Throughout Great Expectations, Dickens makes many references to Shakespeare. The reference to Macbeth is used so readers can make a connection to another and familiar piece of literature. In Macbeth, Lady Macbeth murders Duncan and then is forced to face serious guilt. This can be connected to Pip's feelings of guilt when he chooses to leave Joe and Biddy.
