Detailed Scene-by-Scene Summary and Analysis

Scene 1: Banquo’s Soliloquy and Macbeth’s Deadly Plot

Summary Act 3 opens with Banquo alone in the palace courtyard, riding horse as day fades to dusk—a perfect symbol of encroaching moral darkness. In a soliloquy (lines 1-10), he reflects on the witches’ prophecies: Macbeth has gained “King, Cawdor, Glamis, all,” but Banquo ponders his own fate—”Thou shalt get kings, though thou be none.” His integrity shines; unlike Macbeth, he resists temptation.

Enter Macbeth and Lady Macbeth, exchanging pleasantries about an evening feast. Once alone, Macbeth reveals his paranoia in another soliloquy. Banquo’s “royalty of nature” threatens him, especially with the prophecy of Banquo’s descendants ruling. Macbeth summons two murderers he previously wronged, manipulating them with lies: “Both of you / Know Banquo was your enemy” (3.1.114-115). A third murderer—likely sent by Macbeth for reliability—joins later. They agree to kill Banquo and his son Fleance that night.

Key Quote: “Thou hast it now: King, Cawdor, Glamis, all, / As the weird women promised, and I fear / Thou played’st most foully for ‘t.” (3.1.1-3, Banquo)

Analysis

Study Tip: Contrast Banquo’s soliloquy with Macbeth’s—Banquo accepts fate morally, while Macbeth defies it through murder. Perfect for essays on “fate vs. free will in Macbeth.”

Scene 2: The Macbeths’ Fractured Marriage

Summary Lady Macbeth, alone, laments their hollow victory: “Nought’s had, all’s spent, / Where our desire is got without content” (3.2.4-5). She has pushed for Duncan’s murder, yet peace eludes them. Seeking her husband, she finds him brooding: “We have scotch’d the snake, not kill’d it” (3.2.13). Macbeth hints at “deeds” without specifics, rejecting her advice to “put on” cheer for the banquet. Instead, he vows to embrace darkness—”Come, seeling night… / And with thy bloody and invisible hand / Cancel and tear to pieces that great bond / Which keeps me pale!” (3.2.46-50). Messengers confirm the murderers’ readiness.

Key Quotes

Deep Dive: This shortest scene (46 lines) is psychologically pivotal. Lady Macbeth, once the “iron” director of crime, now plays second fiddle. Macbeth’s secrecy signals their marriage’s fracture—he acts alone, a lone wolf in moral wilderness.

Expert Insight: Shakespeare draws from Elizabethan psychology here. Renaissance thinkers like Robert Burton in Anatomy of Melancholy described ambition as a “humour” imbalance leading to melancholy. Macbeth’s isolation foreshadows Lady Macbeth’s sleepwalking in Act 5, where roles reverse.

Scene 3: The Murder of Banquo – Tension and Tragedy

Summary Under a moonlit grove near the palace, three murderers await Banquo and Fleance, torches flickering. Banquo arrives, sensing danger: “Who’s there?” (3.3.3). They attack; Banquo cries, “O treachery! Fly, good Fleance, fly, fly, fly!” (3.3.18), dying as his torch extinguishes—symbolizing conscience’s death. Fleance escapes into darkness. The murderers report partial success to Macbeth, who reacts with horror: “Then comes my fit again” (3.3.20, stage direction implied).

Key Quote: “Fly, good Fleance, fly, fly, fly!” (3.3.18, Banquo)

Analysis

• Dramatic Irony: We know the witches prophesied Banquo’s line would inherit the throne—Fleance’s escape dooms Macbeth.
• Symbolism: The snuff’d torch = failing moral light; darkness triumphs.
• Third Murderer Mystery: Scholars debate his identity (witch? Macbeth’s spy?). RSC productions often stage him as supernatural for menace.

Visual Aid: Assassination Timeline

1. Murderers hide (lines 1-6)
2. Banquo/Fleance arrive (7-17)
3. Attack; torch out (18-25)
4. Fleance flees (26-30)

Common Exam Question: Why does Fleance’s escape matter? Answer: It directly challenges the witches’ prophecy, fueling Macbeth’s paranoia and ensuring his tragedy’s irony—he murders to secure a throne he can’t pass on.

Scene 4: The Banquet Scene – Macbeth’s Public Breakdown

Summary The banquet’s midpoint: Lords toast Macbeth, who enters smiling. A murderer whispers Banquo’s death—but Fleance lives. Macbeth’s joy shatters as Banquo’s ghost enters, bloodied, sitting in his place. Only Macbeth sees it: “Thou canst not say I did it. Never shake / Thy gory locks at me” (3.4.49-50). He rants, drawing swords; Lady Macbeth covers, blaming “old ghosts.” The ghost vanishes; Macbeth recovers, only for it to reappear. Chaos peaks: “Avaunt! and quit my sight! Let the earth hide thee!” (3.4.108). Lords whisper rebellion; Macbeth vows more “deeds.”

Key Quotes (with Line-by-Line Breakdown)

Analysis Layers

Expert Insight: In Elizabethan England, ghosts signified unresolved sin (per Hamlet). Here, Banquo’s is Macbeth’s conscience externalized—unlike Lady Macbeth’s suppressed guilt. Modern productions (e.g., 2021 RSC) use projections for the ghost, amplifying psychological horror.

Study Tip: Memorize lines 40-108. They’re 90% of AP Lit quote IDs and perfect for “How does Shakespeare portray guilt?” essays.

Scenes 5-6: Witches, Hecate, and Lennox’s Subtle Rebellion

Summary Scene 5 (controversial, possibly non-Shakespearean): Witches meet Hecate, goddess of witchcraft, who scolds them for meddling without her: “And you all know, security / Is mortals’ chiefest enemy” (3.5.32-33). She plans Macbeth’s “irrevocable” doom.

Scene 6: Lennox converses with a lord, sarcastically praising Macbeth’s “good” reign—irony drips as he reveals Macduff’s flight to England and growing rebellion.

Key Quote: “And you all know, security / Is mortals’ chiefest enemy.” (3.5.32-33, Hecate)

Analysis

• Scene 5 Debate: First Folio includes it, but editors like Arden omit. It explains witches’ motives but feels didactic.
• Lennox’s Irony: “Men must not walk too late” (3.6.7)—subtle signal of resistance, contrasting Act 1 loyalty.

Debate: Include Scene 5 in productions? Yes for spectacle; no for pacing (per Globe Theatre notes).
