Peleus

Peleus was the son of Aeacus, king of the island of Aegina, and the nymph Endeïs. He was a friend of Heracles, serving in the latter's expedition against the Amazons and his war against King Laomedon. He and his brother Telamon accidentally killed their half-brother Phocus, and fled to Phthia to escape punishment. There, Peleus married King Eurytion's daughter Antigone, but was again forced to flee when he accidentally killed Eurytion during the hunt for the Calydonian Boar. After his first wife's death, he married the sea-nymph Thetis, and their wedding feast marked the beginning of the quarrel that led to the Judgement of Paris and eventually to the Trojan War. With Thetis, he fathered Achilles and, according to some sources, Thetis made Peleus immortal and he outlived both his son, Achilles, and his grandson, Neoptolemus.
