Calliope was the muse of heroic poetry, daughter of Zeus and Mnemosyne, and is now best known as Homer's muse, the inspiration for the Iliad and the Odyssey. One account says Calliope was the lover of the war god Ares, and bore him several sons: Mygdon, Edonus, Biston, and Odomantus - 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.
