God of revelry. Milton represents him as a male Circe. (Greek, komos, carousal.)
This nymph [Circe], that gazed upon his [Bacchus's] clustering locks, ... Had by him, ere he parted thence, a son, Much like his father, but his mother more, Whom therefore she brought up, and Comus named.
Milton: Comus, 54-58.
