Calliope

One of the nine Muses, Calliope was the Muse of epic poetry, and was pictured with a tablet and stylus, or with a scroll.
She had many children by different gods: Carybantes by Zeus, Hymen, Ialemus and Linus by Apollo, Rhesus by the river Strymon, the Sirens, Orpheus and Oeagrus. All of these children, except Rhesus, had to do with music or poetry.
Calliope had a special weakness for Achilles, and taught him how o entertain and enhance the morals of his friends by singing at their feasts.
When Aphrodite and Persephone argued who would get Adonis, Calliope was called in by Zeus as mediator. Her decision was that each goddess would be with him a certain part of the year.
