Juliet's physicality is an important theme when discussing this play, as she and Romeo fall in love at first sight and their chemistry is at least partially based upon their physical attraction. The famous balcony love scene finds Romeo comparing Juliet to the sun rising in the East: a symbol of new hope and new beginnings, significant for Romeo who has just come out of a failed relationship. "Arise, fair sun, and kill the envious moon" hints that Juliet's persona is bright and cheery, without the melancholy he has previously associated with his lovers. Juliet is often described by Romeo with imagery related to light and to birds.
In Act I, Scene 5, he describes her thus:
"Oh, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
Like a rich jewel in an Ethiope’s ear,
That runaway's eyes may wink and Romeo
Leap to these arms, untalk'd of and unseen."
For thou wilt lie upon the wings of night
Whiter than new snow on a raven's back.
Come, gentle night, come, loving, black-brow'd night,
Give me my Romeo; and, when he shall die,
Take him and cut him out in little stars,
And he will make the face of heaven so fine
That all the world will be in love with night
And pay no worship to the garish sun."
