• Motif of alsep:


  The motif of sleep in the play becomes synonymous with the loss of innocence. As Macbeth grapples with guilt, he declares he"sleeps no more," echoing

  Lady Macbeth's somnambulant state.Intriguingly, Banquo retains the capacity to sleep but acknowledges his ability to "dream." This contrast illuminates Banquo's preservation of innocence, as he truthtully admits to being captivated by the supernatural without succumbing to guilt-induced insomnia like Macbeth and Lady Macbeth.
• Foll Maabeil:


  Banquo's sincerity operates as a foil to Macbeth's deceit, as Macbeth falsely asserts that he does not "think" of the prophecies. Banquo's moral characterisation is strategically employed to heighten the contrast with Macbeth's dishonesty and duplicity . This deliberate juxtaposition serves to accentuate the moral divergence between the two characters.
