In Greek mythology, Peleus was a hero, king of Phthia, husband of Thetis and the father of their son Achilles. This myth was already known to the hearers of Homer in the late 8th century BC.

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.
