Banquo

Banquo is a Scottish general of unquestioned battlefield courage who opens the play as Macbeth's equal and closest companion. Captain's report and Duncan's own gratitude confirm that both men fought with extraordinary valour against the Norwegian invaders in Act I, Scene ii. What sets Banquo apart from his friend, however, is not military ability but moral temperament. Where Macbeth is a man of explosive imagination and appetite, Banquo is measured, observant, and suspicious of easy promises. He is never naïve—he knows the Witches may be agents of hell—yet he is no saint either. His refusal to expose Macbeth after Duncan's murder reveals a man capable of self-interested silence, a flaw Shakespeare embeds in an otherwise admirable character to keep him human rather than merely symbolic.

Banquo's arc is defined less by action than by deliberate inaction, and the tragedy lies precisely there. In Act I he is a warrior-peer, co-recipient of supernatural prophecy, and trusted counsellor to a king. The Witches tell him he will be "lesser than Macbeth, and greater," and that though he will never reign, he will father a line of kings. He receives this with measured curiosity rather than hunger.

The pivot comes after Duncan's murder. Banquo confesses in Act II, Scene i that the Witches' words have been weighing on his sleep, and in Act III, Scene i he privately acknowledges his suspicion that Macbeth has "played'st most foully" for the crown—yet he chooses silence. His motivation here is ambiguous and troubling: the prophecy that his descendants will rule may make him reluctant to tear down a regime that, however corrupt, keeps that dynastic possibility alive. This moral compromise costs him his life and, in a grim irony, illustrates that the Witches ensnare even those who think themselves immune to their temptations.

The heath (Act I, Scene iii): Banquo's first response to the Witches is to question their reality—"Are ye fantastical, or that indeed / Which outwardly ye show?"—and later to warn that "the instruments of darkness tell us truths / Win us with honest trifles, to betray's / In deepest consequence." This is the play's clearest early statement of its central moral theme, delivered by a man who will nonetheless be destroyed by the prophecy he mistrusts.

The sleepless soliloquy (Act II, Scene i): Just before Macbeth's dagger hallucination, Banquo confides to Fleance that "merciful powers" must restrain the "cursèd thoughts that nature / Gives way to in repose." The admission that dark temptation visits him too makes his subsequent restraint a genuine choice rather than a default, elevating him above simple foil status.

The banquet ghost (Act III, Scene iv): Dead, Banquo is more powerful than he ever was alive. His ghost—visible only to Macbeth—occupies the king's seat and drives him to incoherent public raving, exposing his guilt to every assembled noble. The ghost speaks no words; its mute, blood-boltered presence is enough to unravel Macbeth's authority in a single evening.

The procession of kings (Act IV, Scene i): Eight monarchs descending from Banquo parade before Macbeth in the Witches' vision, the last holding a mirror "which shows me many more." The image confirms that every crime Macbeth has committed has secured nothing—Banquo's line will inherit Scotland regardless.

With Macbeth: Their fraternal bond—forged in shared danger and mutual respect—makes Macbeth's decision to have him murdered the clearest marker of his complete corruption. Banquo's ghost at the banquet is therefore not just supernatural guilt but the literalisation of destroyed friendship; Macbeth cannot look at the seat Banquo should rightfully occupy without confronting what he has obliterated.

With the Witches: Banquo engages the Witches intellectually rather than emotionally, demanding they speak to him too—"Speak then to me, who neither beg nor fear / Your favours nor your hate." His prophecy is no less powerful for his scepticism, however; it makes him a target for Macbeth's paranoia just as surely as if he had welcomed it with open arms.

With Duncan: Banquo's loyalty to Duncan mirrors Macbeth's outward loyalty while being genuine. When Duncan is murdered, Banquo calls for God's help against "treasonous malice," a cry of sincere grief that implicitly judges the silence he later keeps about his suspicions.

With Fleance: His relationship with his son is the play's quiet counter-symbol to Macbeth's childless tyranny. Banquo's final act before the ambush is to urge Fleance to run, ensuring the dynastic promise survives. Fleance escapes into darkness and into history—Shakespeare's audience would have recognised him as the legendary ancestor of the Stuart kings.
