Thalia
tha-li'a, in Greek mythology, the muse of comedy. She was called at an earlier period the Joyful Muse, for she was supposed to inspire gaiety and rural pleasures. She presided at banquets where music and song accompanied the festivities. Later she became the muse of comedy. She was the mother, by Apollo, of the Corybantes, priests of Cybele, who worshiped that goddess with dancing, to the accompaniment of drum and cymbal. Thalia is represented in art crowned with ivy. She carries a shepherd's crook and has a comic mask in one hand. See Muses
