Fragments from a woman’s statue identified with Amphitrite. Preserved are parts of her left forearm and her right thigh. The woman drove her husband’s, Poseidon's, chariot. Albeit no traces of the chariot are retained, Amphitrite was most possibly depicted dismounting the chariot wearing a chiton that left her left leg bare.

The thigh fragment was recovered in 1932 during the excavation expeditions conducted in the Athenian Agora built in a modern house whereas the location that the forearm was found remains unknown. It is probable that both fragments fell off the pediment in 1687 during the bombardment of the Parthenon by the Venetians under general Francesco Morosini. The remaining torso of Amphitrite is a plaster cast of the original kept in the British Museum in London after it was removed by Thomas Bruce, lord of Elgin, who was in Greece between 1801-1804, when the country was still under Ottoman rule, and forcibly detached most of the sculptures of the pediment still in their original position.

The west pediment of the Parthenon portrays the dispute between Athena and Poseidon regarding who would become the divine protector of Athens. The contest was held on the Acropolis in the presence of the city’s mythical kings Kekrops and Erechtheus and other local heroes, who as judges decided the outcome in favour of Athena, preferring her gift, the olive tree, to the salty water offered by Poseidon. The centre of the scene is occupied by the two protagonists and their chariots whereas the pediments' corners contain the personifications of two rivers that flowed in ancient Athens, Ilissos and Kephissos. Due to the misadventures suffered by the monument over the following centuries many sculptures have been lost, some survive in mutilated form whereas others are represented only in small fragments.

The two Parthenon pediments are adorned with about fifty oversized statues. The sculptures, perfectly worked even on their unseen, rear sides, present scenes from the myths of the goddess Athena.
