Poseidon and Amymone
Danaos, a mythical king, had fifty daughters whom he sent out to find water during a great drought. One of them, Amymone, was accosted by a satyr but rescued by the sea god, Poseidon, who sought her favors for himself. In return, he struck the earth with his trident and created a spring. The vase shows Poseidon and Amymone seated on either side of Eros, the god of love, and a waterbird.
