Calliope is the muse of epic poetry, and the daughter of Mnemosyne and Zeus. She is believed to be Homer's muse, the inspiration of the Iliad and Odyssey. 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. She taught Orpheus verses for singing. According to Hesiod, she 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, she is depicted as carrying a roll of paper or a book or as wearing a gold crown.
