 Studying Macbeth. Let's discuss key quotes relating to Macbeth's guilt when he sees hallucination of Banquo's ghost. When Banquo's ghost reappears Macbeth is panicked he says, avant inquite my sight, late the earth hide thee. Now these exclamatory sentences are a contrast to how Macbeth was at the beginning of the play. Here he seems really cowardly as opposed to how valiant and brave and noble he was at the beginning. He's horrified by what he sees he says thy bones are marrowless, thy blood is cold and the repetition of thy shows Macbeth is almost unable to behold what is the dead body of Banquo as a ghost even if he's the one that caused him to be killed. Macbeth notices thou hast no speculation in those eyes in other words Banquo's ghost the eyes seem lifeless. Now he speaks here in Iron Bit Pentameter again showing his horror at Banquo's ghost however bear in mind that he notices that Banquo's eyes even if they're lifeless they're glaring at him. Now the verb glare showed that he's feeling guilty that Banquo is so angry at him for betraying him and having him killed.
