Using her own considerable influence and wealth, Regilla erected a great nymphaeum (a monumental fountain) at Olympia. Her husband constructed an aqueduct that fed the nymphaeum. The fountain that Regilla built made the cool refreshing water available to the people in this hot, dusty area. In the centre of the nymphaeum stood a life-sized statue of a bull. On that bull there is an honorific inscription dedicated to Regilla stating: “Regilla, priestess of Demeter, dedicated the water and the things around the water to Zeus”. At Olympia, bulls were sacrificed at the Temple of Zeus, the chief divinity of Olympia.
