Eight ithyphallic satyrs, alternately playing the double aulos and the syrinx with their legs bent, appear to take part in a procession, alternating with the eight sirens. Like the sirens, their hybrid nature symbolizes the connection between the world of the living and that of the dead. In particular, the erect phallus alludes to the concept of rebirth. They belong to the celestial dimension, as they are represented in the constellation that replaces Sagittarius.
