"Swung by Seraphim whose foot-falls tinkled on the tufted floor."
Explanation:
the narrator references the Bible by referencing Seraphim, six-foot tall winged creatures whose job in biblical lore was to fly around God’s throne and praise him by repeating “Holy” over and over. These Seraphim are similar to the raven in the fact that they can only say one word.
