Question

What figure of speech is used in these lines from William Shakespeare’s Romeo and Juliet? But all so soon as the all-cheering sun Should in the furthest east begin to draw The shady curtains from Aurora's bed, Away from the light steals home my heavy son, And private in his chamber pens himself, Shuts up his windows, locks far daylight out And makes himself an artificial night: Black and portentous must this humour prove, Unless good counsel may the cause remove.
A. simile
b. Allusion
c. Oxymoron
d. pun

Answer 1

I would say that Shakespeare uses allusion in this excerpt from Romeo and Juliet. He is alluding, or making a reference to Aurora, who is a character/person outside of Romeo and Juliet.

Answer 2

The answer is allusion because

allusion : an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference.

b. Allusion
