In Shakespeare's "Romeo and Juliet," the beauty of Juliet is likened to celestial bodies, emphasizing her radiant charm. The quote suggests that her cheeks outshine the stars, and during the day, they are as bright as a lamp. This comparison highlights how her physical attributes surpass even the brightest lights of the night sky.

Furthermore, the imagery of her eyes being so luminous that birds sing, mistaking it for daytime, captures the enchanting effect she has on the world around her. This illustrates not only her beauty but also the profound impact she has on nature and those who see her, reinforcing the theme of love and admiration in the play.
