In Act 2, scene 2, Romeo spies on Juliet from her garden as she stands on her balcony. The party has just ended and the lovers have realized each other's true identity. Smitten, Romeo has resorted to stalker tactics and Juliet has isolated herself to mourn her new crush.
Romeo begins Act 2, scene 2, by using light and dark imagery to compare Juliet's beauty to that of the sun's brilliance in the morning. He mentions the moon as a pale imitation to the sun and notes that others must be jealous of how beautiful Juliet is.
"But soft! What light through yonder window breaks?
It is the east, and Juliet is the sun.
Arise, fair sun, and kill the envious moon" (2, 2, 2-5)
He continues to use the light/dark imagery as he compares the twinkling of Juliet's eyes to the stars in the skies and how her cheek's brightness could shame the real stars to dim.
