Question

Which literary device does Dickinson begin with the phrase "setting sun"? alliteration metaphor personification sarcasm

Answer 1

A metaphor is comparing two unlike objects without the use of the words like or as.  Metaphors are usually symbolic.  An alliteration is a group of words that have similar letters or sounds.  Personification is giving an inanimate object the characteristics that a person would have.  Sarcasm is the use of irony to mock.  You must decide from here.
