Answer:
The metaphor for romance encourages the "contemplation of the beautiful" that Poe explains.
Step-by-step explanation:
The poem "Romance" by Edgar Allen Poe is about love and how finding it is a task which he does not have time for. And though he did not have time for love, he admits he could not stop his heart from trembling.
His essay "The Poetic Principle" argues why he thinks that art must be written for arts’ sake. It is a criticism, sort of, for any artistic work.
And in the given excerpt from the poem "Romance", Poe's metaphor of romance encourages the "contemplation of the beautiful" that he explains in the essay.
