 Studying Macbeth? Here's how you can analyse Act 2, Scene 1. Shakespeare uses pathetic fallacy when Banco and his son, Fleance, are patrolling in order to create a really dark mood. Banco senses someone else and he asks who's there and Macbeth says a friend. This is dramatic irony because Macbeth is an enemy, he's literally about to kill the king. Banco tells Macbeth that King Duncan is asleep, however he has been an unusual pleasure, in other words he's really happy, and alliteration here emphasises how King Duncan thinks that Macbeth and Lady Macbeth are the perfect hosts. Banco then confesses to Macbeth, I dreamt last night of the three weird sisters, in other words he dreamt of the witches, and the alliteration pathetic fallacy shows that he's haunted by their prediction. Yet Macbeth lies and says, I think not of them, this declarative sentence shows he's being deceptive, he's lying to Banco. Yet even if Banco is thinking of the witches he still keeps my bosom, franchise and allegiance clear. Assenance has used her to show that Banco is still really loyal to the king.
