“"Will all great Neptune's ocean wash this blood clean from my hand?"”

Macbeth · Act 2, Scene 2

Focus: “blood”

Immediately after murdering Duncan, Macbeth recognises the permanence of his guilt — no amount of water can cleanse the stain of regicide.

Technique 1 — HYPERBOLIC CLASSICAL ALLUSION

AO2

The reference to Neptune elevates Macbeth's guilt to mythological proportions — even the entire ocean cannot cleanse his hands. This hyperbole reveals that Macbeth understands his crime is not merely legal but metaphysical — he has stained his soul, not just his hands.

The image creates a devastating scale contrast: the vastness of Neptune's ocean versus the smallness of a human hand. Yet the hand's guilt outweighs the ocean, inverting natural proportions and suggesting that moral corruption is more powerful than any natural force of purification.

Key Words

Neptune— The Roman god of the seaHyperbole— Deliberate exaggeration for emphasis or effectMetaphysical— Beyond the physical; relating to abstract concepts of existence and reality

RAD — REGRESS

AO2

Macbeth's regression deepens: he has crossed the irreversible threshold of murder. Yet paradoxically, his awareness of guilt demonstrates that his moral faculty has not been entirely destroyed — he can still recognise the enormity of his act. This creates tragic pathos: we witness a man who knows he has damned himself but cannot undo what he has done.

Key Words

Tragic pathos— A quality that evokes pity and sorrow in the audienceIrreversible— Unable to be undone or reversed

Technique 2 — MOTIF OF BLOOD / EXTENDED METAPHOR

AO2

Blood functions as an extended metaphor for guilt across the entire play. Here it begins as literal (Duncan's blood on Macbeth's hands) but transforms into symbolic — the blood represents moral contamination that cannot be removed. This motif later transfers to Lady Macbeth ('Out, damned spot!'), creating a structural parallel between the couple's psychological disintegration.

The answering line — 'this my hand will rather the multitudinous seas incarnadine, making the green one red' — extends the image: rather than the sea cleansing Macbeth, Macbeth will stain the sea. Incarnadine is a rare, Latinate word that slows the line, forcing the audience to absorb its horror before the brutal simplicity of 'making the green one red'.

Key Words

Extended metaphor— A metaphor that is sustained and developed throughout a passage or textIncarnadine— To turn something blood-red; to stain crimsonMultitudinous— Very numerous; vast in number

Context (AO3)

AO3

REGICIDE & DIVINE LAW

Under the Divine Right of Kings, murdering a monarch was not merely a crime against the state but against God. Macbeth's sense that no natural element can cleanse him reflects the Jacobean belief that regicide creates a spiritual stain that only divine forgiveness — which Macbeth never seeks — could remove.

LADY MACBETH'S CONTRASTING RESPONSE

'A little water clears us of this deed' — Lady Macbeth's dismissive response creates a dramatic contrast. Her inability to see the moral weight of the murder foreshadows her later psychological collapse, when the blood she dismissed returns to haunt her in the sleepwalking scene.

Key Words

Spiritual stain— A moral corruption believed to mark the soul permanentlyDismissive— Treating something as unworthy of serious considerationForeshadow— A warning or indication of a future event in a narrative

WOW — EXISTENTIAL GUILT (Kierkegaard)

AO1AO2

Søren Kierkegaard's concept of existential dread describes the anxiety that accompanies awareness of one's own freedom to choose evil. Macbeth's ocean image captures this perfectly: he has exercised his freedom (choosing to murder) and now confronts the irreversible consequence of that choice. The guilt is not merely emotional but ontological — it has changed what Macbeth IS, not just what he has done. This aligns with Aristotle's concept of hamartia: Macbeth's crime is not an accident but a choice that fundamentally alters his identity. Shakespeare presents guilt as existential transformation — the murderer is not the same person as the loyal thane; the act has created a new, damned self.

Key Words

Existential dread— Profound anxiety arising from awareness of one's freedom and responsibilityOntological— Relating to the nature of existence and beingHamartia— A tragic flaw or error in judgment that leads to a character's downfall
