In Greek mythology, Calliope (Greek: Καλλιoπε, beautiful-voiced) was the muse for epic poetry. She had two sons, Orpheus and Linus with Apollo. She was the oldest and wisest of the Muses. She was the judge in the argument over Adonis between Aphrodite and Persephone. She was represented by a stylus and wax tablets.
