The brightness of her cheek would shame those stars,
As daylight doth a lamp; her eyes in heaven
Would through the airy region stream so bright
That birds would sing and think it were not night.

– William Shakespeare

Romeo and Juliet, Act 2, Scene 2. Romeo uses light imagery to tell us how glorious Juliet is to him in the play’s most famous scene, commonly known as the balcony scene. Hiding in Capulet’s orchard after the ball, he sees Juliet leaning out of her balcony window overhead. Using a simile, he says that the radiance of her cheeks overpowers the stars, just as daylight does a lamp. The brightness of her eyes would make the birds sing, thinking it was day and not night.
