This is a particularly straightforward poem about love and sleep. It has certain elements of the Gothic, such as the description of his love’s “smooth skinned…bare throat need to bite.” This line brings about images of vampires, hence the reference to the Gothic. The rest of the poem, however, does not rely on any Gothic images and instead focuses on details of the woman’s face. Delight is capitalized but not personified. I think it is capitalized for emphasis, in order to give the word more weight.
