Without having the paragraph itself to read, I will make my best educated guess.
Since the definition of emphasis is "special importance, value, or prominence given to something," I would imagine the answer is importance since it is in the definition.
If this is incorrect please add the paragraph to the question so we can have some context.
Cupid, because he was used a lot in early English Poetry. And also, I remember in english talking about all the allusions relating to Cupid Shakespeare made. Hope this helped :)
