James I and Banquo
In Shakespeare's Macbeth Banquo is often presented as a character of great virtue and nobility contrasting sharply with Macbeth's ambition and ruthlessness.
Banquo is not depicted as a perfect virtuous character but rather as a complex figure who struggles with the temptations of fate and the lure of power.
Resisting Temptation
Despite being tempted by the witches' prophecies Banquo ultimately resists succumbing to their influence and remains steadfast in his loyalty to Duncan.
Loyalty and Honesty
Banquo is portrayed as a loyal friend to Macbeth and a loyal servant to King Duncan resisting Macbeth's attempts to involve him in the murder plot.
Why is Banquo Portrayed Like This
The reason Banquo is set as a character of virtue is because King James I believed he was related to Banquo even though there is over 500 years between their lives.
Remember Banquo is the foil or virtuous antithesis to Macbeth who's son (Fleance) escapes to begin a family line leading all the way to King James I.
To help remember that Banquo is related to King James I see the following mnemonic:
