How the supernatural works in Macbeth
The supernatural is where the play begins, with three witches on a heath, and its shadow falls over everything that follows. But Shakespeare is careful. The witches never tell Macbeth to kill anyone. They simply plant a prophecy and let his own ambition do the rest. The supernatural in this play works by temptation and suggestion, not command, which raises the play's central question: is Macbeth fated to fall, or does he choose it?
The witches also introduce the idea of equivocation, of truths that deceive. Their prophecies are all technically true and yet lead Macbeth to disaster, because he hears what he wants to hear. Around them, Shakespeare builds a whole atmosphere of the unnatural: a dagger that floats in the air, a murdered friend who returns as a ghost, a night when the natural world convulses. The supernatural is the outward sign that Macbeth has broken the God-given order.
Key supernatural quotes in Macbeth
“Fair is foul, and foul is fair”
Where: Act 1 Scene 1The witches' opening chant, and the moral key to the play. Good and evil, fair and foul, have been turned upside down. Argue that this inversion spreads through the whole play, and note that Macbeth unknowingly echoes it in his first line, linking him to the witches from the start.
“All hail, Macbeth, that shalt be king hereafter!”
Where: Act 1 Scene 3The prophecy that lights the fuse. The witches name Macbeth's deepest desire aloud. Notably, they only predict, they do not instruct. Use it to argue that the supernatural tempts rather than commands, leaving Macbeth's choice, and his guilt, his own.
“By the pricking of my thumbs, / Something wicked this way comes”
Where: Act 4 Scene 1A witch senses Macbeth approaching and calls him 'wicked'. Chilling because it shows Macbeth is now the evil the supernatural recognises as its own. Argue that he has crossed fully into their world by this point in the play.
“none of woman born / Shall harm Macbeth”
Where: Act 4 Scene 1The apparition's prophecy that makes Macbeth feel invincible. It is equivocation, a truth that deceives, since Macduff was born by caesarean. Use it for the theme of the supernatural misleading through half-truths, and for how it feeds Macbeth's fatal overconfidence.
“Macbeth shall never vanquished be until / Great Birnam Wood to high Dunsinane Hill / Shall come against him”
Where: Act 4 Scene 1The second deceptive prophecy. Impossible on the surface, it comes true when soldiers carry branches from Birnam Wood. Argue that the witches trap Macbeth with truths he misreads, so the supernatural does not force his fall, it lures him into it.
“Double, double toil and trouble; / Fire burn, and cauldron bubble”
Where: Act 4 Scene 1The witches' incantation as they brew their charm. The hypnotic rhythm and grotesque ingredients build an atmosphere of dark, chaotic power. Use it to show how Shakespeare makes the supernatural vivid and threatening on stage, and how far Macbeth has sunk to seek it out.
How the supernatural develops across the play
The supernatural frames the entire play. It opens the action, with the witches deciding to meet Macbeth, and it drives the plot at every turn. In Act 1 they plant the prophecy that tempts him. In Act 2 the dagger floating before the murder shows the supernatural leaking into Macbeth's own mind, and Lady Macbeth has already called on 'spirits' to make her cruel.
As Macbeth's guilt grows, so does the supernatural: Banquo's ghost invades the banquet in Act 3, a visitor from beyond that only Macbeth can see. By Act 4 he actively seeks the witches out, and they deceive him with the equivocating apparitions that make him feel untouchable. The supernatural then turns on him in Act 5, as the impossible prophecies come true and Birnam Wood 'moves'. Across the play, the supernatural shifts from tempter, to reflection of his guilt, to the trap that destroys him.
Using the supernatural in the exam
The sharpest point you can make is that the witches tempt but never command. They predict Macbeth will be king; they never tell him to murder Duncan. That lets you argue about fate versus free will, which is exactly the debate Shakespeare wants, and it stops your answer from letting Macbeth off the hook. Use 'All hail, Macbeth' for the temptation and the equivocating prophecies for the deception.
For context, remember that King James I was fascinated by witchcraft and even wrote a book on it, so the witches would have gripped a Jacobean audience who genuinely feared such powers. The supernatural also signals the breaking of the natural order.
