(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.
