In Greek mythology, Telamon was the son of King Aeacus of Aegina, and Endeïs, a mountain nymph. The elder brother of Peleus, Telamon sailed alongside Jason as one of his Argonauts, and was present at the hunt for the Calydonian Boar. In the Iliad, he was the father of Greek heroes Ajax the Great and Teucer by different mothers. Some accounts mention a third son of his, Trambelus. He and Peleus were also close friends of Heracles, assisting him on his expeditions against the Amazons and his assault on Troy.

Aeacus was a mythological king of the island of Aegina in the Saronic Gulf. He was a son of Zeus and the nymph Aegina, and the father of the heroes Peleus and Telamon. According to legend, he was famous for his justice, and after he died he became one of the three judges in Hades alongside Minos and Rhadamanthos. In another story, he assisted Poseidon and Apollo in building the walls of Troy.
