(extract from the museum explanatory note) - On the left, Demeter (Ceres), the Goddess of agricultural abundance, clad in a peplos and himation (cloak) and holding a scepter. On the right is Persephone (Proserpina), her daughter and the wife of Hades, the God of the underworld. She is dressed in a chiton and himation. Each Goddess extends her right hand toward the nude youth. The boy is thought to be Triptolemos, who was sent by Ceres (Demeter) to teach men how to cultivate grain. The Eleusinian mysteries were a secret cult to honor Ceres.
