Selene (moon) in chariot and Nyx (night) fight giants
The relief shows two giants, one young and one old, and two goddesses. The goddess Selene is identified by the crescent moon around her head. She rides in a chariot pulled by two bulls and driven by a winged putto, who represents Hesperos. Hesperos , the evening-star, is a standard escort of Selene in the same way that Phosphoros, the morning-star, announces the arrival of Helios. In the background, behind the team, is the bust of a goddess who is veiled; she is probably Nyx or Night. This relief shows the onset of night that terminated the battle. The relief is the best preserved of this series found at the Propylon of Diogenes. The destruction of the faces of the divinities was probably due to intentional defacing in the Christian period.
