In Greek mythology, Calliope (pron.: /kəˈlaɪ.əpiː/ kə-ly-ə-pee; Ancient Greek: Καλλιόπη Kalliopē "beautiful-voiced") was the muse of epic poetry, daughter of Zeus and Mnemosyne, and is believed to be Homer's muse, the inspiration for the Odyssey and the Iliad.
One account says Calliope was the lover of the war god Ares, and bore him several sons: Mygdon, Edonus, Biston, and Odomantus (or Odomas), respectively the founders of Thracian tribes known as the Mygdones, Edones, Bistones, and Odomantes.
Calliope also had two famous sons, Orpheus and Linus, by either Apollo or the king Oeagrus of Thrace. Calliope taught Orpheus verses for singing. According to Hesiod, Calliope was also the wisest of the Muses, as well as the most assertive. Calliope married Oeagrus close to Pimpleia, Olympus.
Calliope is always seen with a writing tablet in her hand. At times, Calliope is depicted as carrying a roll of paper or a book or as wearing a gold crown.
