Setting the Scene: Witches, War and Prophecy
Act I opens with three witches meeting during a thunderstorm, immediately establishing the supernatural and eerie tone that runs throughout the play. They plan to meet Macbeth "when the battle's lost and won," setting up the theme of disorder and moral ambiguity.
King Duncan receives news of battle from a wounded captain, who praises Macbeth's bravery against rebel forces. Duncan decides to execute the traitorous Thane of Cawdor and give his title to Macbeth. At this point, Shakespeare presents Macbeth as a stereotypical hero and ideal warrior - giving him a noble status from which he can fall, a key element of tragic heroes.
In a pivotal scene, Macbeth and Banquo encounter the witches who address Macbeth with three prophecies: Thane of Glamis (his current title), Thane of Cawdor (which the audience knows is true but Macbeth doesn't), and "king hereafter." They also tell Banquo his children will become kings. When Ross arrives to inform Macbeth he's now Thane of Cawdor, Macbeth is amazed and begins to wonder if he really will become king.
Food for thought: Notice how Banquo warns Macbeth about the witches: "The instruments of darkness tell us truths, to win us to our harm." What does this suggest about how evil might operate in the play?
