[enters with a taper]

• [taper] provides light which is emblematic of how Lady Macbeth is seeking light, hope and solace in her eternal mental darkness.
• in christian symbolism, light often represents hope and divine guidance.
• Thus entering with it can be seen as a desperate grasping for solace and perhaps even a subconscious plea for god's redemption from the sins that torment her.
• her need for light is the antithesis to her earlier presentation in Act 1 when she calls upon the night, wanting darkness to help fuel her violent and malevolent plans ("come thick night")
• The motif of dark and light reinforces how Lady Macbeth's depraved and dark wants for violence consequently cause her desperation to see the light and seek redemption.
