Telamon and his brother Peleus killed their half-brother Phocus, and had to flee Aegina. Telamon went to Salamis, where King Cychreus befriended him and eventually bequeathed him the kingdom. Telamon married Periboea, and had a son, Ajax, by her. He also accompanied Heracles when that hero sacked the city of Troy and killed its king, Laomedon. Telamon received Laomedon's daughter, Hesione, as a battle-prize; by her he had another son, Teucer. Ajax and Teucer were among the Greek heroes who later beseiged and destroyed Troy in the Trojan War.
Telamon was the son of Aeacus, King of Aegina. He was one of the Argonauts who accompanied Jason on the quest for the Golden Fleece, and was present at the hunt for the Calydonian boar.
