What are some metaphors and similes in the first act of Romeo and Juliet?

There are many metaphors and similes in the first act of this play. While both are examples of figurative language, a simile is when the writer compares one thing to another using "like" or "as" while a metaphor is a means of describing something by applying a description of something else to it. For example, when Romeo says "love is a smoke raised with the fume of sighs," he is using a metaphor to better convey his opinion through imagery. Later, in discussing Paris as a marriage prospect for Juliet, Lady Capulet and the Nurse describe him as "a flower," another metaphor.
Benvolio uses an example of simile when he describes a Cupid "scaring the ladies like a crow-keeper." More romantically, when Romeo first sees Juliet, he says that she "hangs upon the cheek of night / Like a rich jewel in an Ethiope's ear." The use of metaphor and simile is a means of illuminating a character's language by providing the audience with a visual image for comparison; here, Romeo is suggesting that Juliet glows and stands out among her peers in a way he cannot help but notice.
