That takes the reason prisoner?
Banquo is a character in William Shakespeare's 1606 play Macbeth. In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches. After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be. Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes. Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.
Shakespeare borrowed the character of Banquo from Holinshed's Chronicles, a history of Britain published by Raphael Holinshed in 1587. In Chronicles Banquo is an accomplice to Macbeth in the murder of the king, rather than a loyal subject of the king who is seen as an enemy by Macbeth. Shakespeare may have changed this aspect of his character in order to please King James, who was thought at the time to be a descendant of the real Banquo. Critics often interpret Banquo's role in the play as being a foil to Macbeth, resisting evil where Macbeth embraces it. Sometimes, however, his motives are unclear, and some critics question his purity. He does nothing to accuse Macbeth of murdering the king, even though he has reason to believe Macbeth is responsible.
Shakespeare often used Raphael Holinshed's Chronicles of England, Scotland, and Ireland—commonly known as Holinshed's Chronicles—as a source for his plays, and in Macbeth he borrows from several of the tales in that work. Holinshed portrays Banquo as an historical figure: he is an accomplice in Mac Bethad mac Findlaích's (Macbeth's) murder of Donnchad mac Crínáin (King Duncan) and plays an important part in ensuring that Macbeth, not Máel Coluim mac Donnchada (Malcolm), takes the throne in the coup that follows. Holinshed in turn used an earlier work, the Scotorum Historiae (1526–7) by Hector Boece, as his source. Boece's work is the first known record of Banquo and his son Fleance; and scholars such as David Bevington generally consider them fictional characters invented by Boece. In Shakespeare's day, however, they were considered historical figures of great repute, and the king, James I, based his claim to the throne in part on a descent from Banquo. The House of Stuart was descended from Walter fitz Alan, the first High Steward of Scotland, and he was believed to have been the grandson of Fleance and Gruffydd ap Llywelyn's daughter, 
Unlike his sources, Shakespeare gives Banquo no role in the King's murder, making it a deed committed solely by Macbeth and his wife. Why Shakespeare's Banquo is so different from the character described by Holinshed and Boece is not known, though critics have proposed several possible explanations. First among them is the risk associated with portraying the king's ancestor as a murderer and conspirator in the plot to overthrow a rightful king, as well as the author's desire to flatter a powerful patron. But Shakespeare may also simply have altered Banquo's character because there was no dramatic need for another accomplice to the murder. There was, however, a need to provide a dramatic contrast to Macbeth; a role that many scholars argue is filled by Banquo. Similarly, when Jean de Schelandre wrote about Banquo in his 
Banquo's role in the coup that follows the murder is harder to explain. Banquo's loyalty to Macbeth, rather than Malcolm, after Duncan's death makes him a passive accomplice in the coup: Malcolm, as Prince of Cumberland, is the rightful heir to the throne and Macbeth a usurper. Daniel Amneus, however, argues that when Ross and Angus bring King Duncan's praise, and the news that Macbeth has been granted the title of Thane of Cawdor, the "greater honor" he ascribes to Macbeth is actually his title as Prince of Cumberland. If Macbeth, rather than Malcolm, is Prince of Cumberland then Macbeth would be next in line to the throne and no coup would be needed, effectively removing this ambiguity from Banquo's character.
Role in the play
Banquo is in a third of the play's scenes, as both a human and a ghost. As significant as he is to the plot, he has fewer lines than the relatively insignificant Ross, a Scottish nobleman who survives the play. In the second scene of the play, King Duncan describes the manner in which Macbeth, Thane of Glamis, and Banquo, Thane of Lochaber, bravely led his army against invaders, fighting side by side. In the next scene, Banquo and Macbeth, returning from the battle together, encounter the Three Witches, who predict that Macbeth will become Thane of Cawdor, and then king. Banquo, skeptical of the witches, challenges them to predict his own future, and they foretell that Banquo will never himself take the throne, but will beget a line of kings. Banquo remains skeptical after the encounter, wondering aloud if evil can ever speak the truth. He warns Macbeth that evil will offer men a small, hopeful truth only in order to catch them in a deadly trap.
When Macbeth kills the king and takes the throne, Banquo—the only one aware of this encounter with the witches—reserves judgment for God. He is unsure whether Macbeth committed regicide to gain the throne, but muses in a soliloquy that "I fear / Thou play'dst most foully for 't". He offers his respects to the new King Macbeth and pledges loyalty. Later, worried that Banquo's descendants and not his own will rule Scotland, Macbeth sends men to kill Banquo and his son Fleance. During the melee, Banquo holds off the assailants so that Fleance can escape, but is himself killed. The ghost of Banquo later returns to haunt Macbeth at the banquet in act three, scene four. A terrified Macbeth sees him, while the apparition is invisible to his guests. He appears again to Macbeth in a vision granted by the Three Witches, wherein Macbeth sees a long line of kings descended from Banquo.
Foil to Macbeth
Many scholars see Banquo as a foil and a contrast to Macbeth. Macbeth, for example, eagerly accepts the Three Witches' prophecy as true and seeks to help it along. Banquo, on the other hand, doubts the prophecies and the intentions of these seemingly evil creatures. Whereas Macbeth places his hope in the prediction that he will be king, Banquo argues that evil only offers gifts that lead to destruction. Banquo steadily resists the temptations of evil within the play, praying to heaven for help, while Macbeth seeks darkness, and prays that evil powers will aid him. This is visible in act two; after Banquo sees Duncan to bed, he says: "There's husbandry in heaven, / Their candles are all out". This premonition of the coming darkness in association with Macbeth's murders is repeated just before Banquo is killed: "it will be rain to-night", Banquo tells his son Fleance.
Banquo's status as a contrast to Macbeth makes for some tense moments in the play. In act two, scene one, Banquo meets his son Fleance and asks him to take both his sword and his dagger ("Hold, take my sword ... Take thee that too"). He also explains that he has been having trouble sleeping due to "cursed thoughts that nature / gives way to in repose!" On Macbeth's approach, he demands the sword returned to him quickly. Scholars have interpreted this to mean that Banquo has been dreaming of murdering the king as Macbeth's accomplice in order to take the throne for his own family, as the Three Witches prophesied to him. In this reading, his good nature is so revolted by these thoughts that he gives his sword and dagger to Fleance to be sure they do not come true, but is so nervous at Macbeth's approach that he demands them back. Other scholars have responded that Banquo's dreams have less to do with killing the king and more to do with Macbeth. They argue that Banquo is merely setting aside his sword for the night. Then, when Macbeth approaches, Banquo, having had dreams about Macbeth's deeds, takes back his sword as a precaution in this case.
Macbeth eventually sees that Banquo can no longer be trusted to aid him in his evil, and considers his friend a threat to his newly acquired throne. Thus he has him murdered. Banquo's ability to live on in different ways is another oppositional force, in this case to Macbeth's impending death. His spirit lives on in Fleance, his son, and in his ghostly presence at the banquet.
When Macbeth returns to the witches later in the play, they show him an apparition of the murdered Banquo, along with eight of his descendants. The scene carries deep significance: King James, on the throne when Macbeth was written, was believed to be separated from Banquo by nine generations. What Shakespeare writes here thus amounts to a strong support of James' right to the throne by lineage, and for audiences of Shakespeare's day, a very real fulfillment of the witches' prophecy to Banquo that his sons would take the throne. This apparition is also deeply unsettling to Macbeth, who not only wants the throne for himself, but also desires to father a line of kings.
Banquo's other appearance as a ghost during the banquet scene serves as an indicator of Macbeth's conscience returning to plague his thoughts. Banquo's triumph over death appears symbolically, insofar as he literally takes Macbeth's seat during the feast. Shocked, Macbeth uses words appropriate to the metaphor of usurpation, describing Banquo as "crowned" with wounds. The spirit drains Macbeth's manhood along with the blood from his cheeks; as soon as Banquo's form vanishes, Macbeth announces: "Why, so; being gone, / I am a man again."
Like the vision of Banquo's lineage, the banquet scene has also been the subject of criticism. Critics have questioned whether not one, but perhaps two ghosts appear in this scene: Banquo and Duncan. Scholars arguing that Duncan attends the banquet state that Macbeth's lines to the Ghost could apply equally well to the slain king. "Thou canst not say I did it", for example, can mean that Macbeth is not the man who actually killed Banquo, or it can mean that Duncan, who was asleep when Macbeth killed him, cannot claim to have seen his killer. To add to the confusion, some lines Macbeth directs to the ghost, such as "Thy bones are marrowless", cannot rightly be said of Banquo, who has only recently died.
Scholars debate whether Macbeth's vision of Banquo is real or a hallucination. Macbeth had already seen a hallucination before killing Duncan: a knife hovering in the air. Several performances of the play have even ignored the stage direction to have the Ghost of Banquo enter at all, heightening the sense that Macbeth is growing mad, since the audience cannot see what he claims to see. Scholars opposing this view claim that while the dagger is unusual, ghosts of murdered victims are more believable, having a basis in the audience's superstitions. Spirits in other Shakespeare plays—notably Hamlet and Midsummer Night's Dream—exist in ambiguous forms, occasionally even calling into question their own presence.
Performances and interpretations
Banquo's role, especially in the banquet ghost scene, has been subject to a variety of interpretations and mediums. Shakespeare's text states: "Enter Ghost of Banquo, and sits in Macbeth's place." Several television versions have altered this slightly, having Banquo appear suddenly in the chair, rather than walking onstage and into it. Special effects and camera tricks also allow producers to make the ghost disappear and reappear, highlighting the fact that only Macbeth can see it.
Stage directors, unaided by post-production effects and camera tricks, have used other methods to depict the ghost. In the late 19th century, elaborate productions of the play staged by Henry Irving employed a wide variety of approaches for this task. In 1877 a green silhouette was used to create a ghostlike image; ten years later a trick chair was used to allow an actor to appear in the middle of the scene, and then again from the midst of the audience. In 1895 a shaft of blue light served to indicate the presence of Banquo's spirit. In 1933 a Russian director named Theodore Komisarjevsky staged a modern retelling of the play (Banquo and Macbeth were told of their future through palmistry); he used Macbeth's shadow as the ghost.
Film adaptations have approached Banquo's character in a variety of ways. In 1936 Orson Welles helped produce an African-American cast of the play, including Canada Lee in the role of Banquo. Akira Kurosawa's 1957 adaptation Throne of Blood makes the character into Capitan Miki (played by Minoru Chiaki), slain by Macbeth's equivalent (Captain Washizu) when his wife explains that she is with child. News of Miki's death does not reach Washizu until after he has seen the ghost in the banquet scene. In Roman Polanski's 1971 adaptation, Banquo is played by acclaimed stage actor Martin Shaw, in a style reminiscent of earlier stage performances. Polanski's version also emphasises Banquo's objection to Macbeth's ascendency by showing him remaining silent as the other thanes around him hail Macbeth as king. in the 1990 telling of Macbeth in a New York Mafia crime family setting, Men of Respect, the character of Banquo is named "Bankie Como" and played by American actor Dennis Farina.
