Which themes are addressed in this stanza from "the raven" by edgar allan poe?

then, methought, the air grew denser, perfumed from an unseen censer
swung by seraphim whose foot-falls tinkled on the tufted floor.

quaff, oh quaff this kind nepenthe and forget this lost lenore! "
quoth the raven, "nevermore."
