The western pediment, which is more conservative in type, represents the earlier expedition of Heracles and Telamon against Troy; the eastern, which is bolder and more advanced, probably refers to episodes in the Trojan war.
His chief exploits during the war were his defence of the wounded Sarpedon, his fight with Ajax, son of Telamon (his particular enemy), and the storming of the Greek ramparts.
By his wife Endeis he was the father of Telamon and Peleus.
The thoroughly national character of Heracles is shown by his being the mythical ancestor of the Dorian dynastic tribe, while revered by Ionian Athens, Lelegian Opus and Aeolo-Phoenician Thebes, and closely associated with the Achaean heroes Peleus and Telamon.
He then, with Telamon, Peleus and Theseus, took Troy.
