The overall subject of the west pediment was the struggle between Athena and Poseidon, by displaying their magic gifts to the people, for patronage over the region of Attica. Poseidon produced water from the ground, while Athena gave the people the first olive tree; she was victorious and Athens bears her name. The west pediment was the one that faced visitors and worshippers as they approached the Parthenon.
The pediment is in a poor state of survival, but drawings made by Jacques Carrey in 1674 show many of the figures now lost, including Athena and Poseidon who dominated the centre. We have casts of two figures from the sides of the pediment. The winged goddess Iris led Poseidon’s chariot and appears to hover above the ground in a striding pose and wearing a short fluttering tunic. The other figure (illustrated) is a youthful, reclining and naked local river god, perhaps Ilissos
