King Priam of Troy's father who had built the city's walls by employing Poseidon and Apollo. The two gods had tried to revolt against Zeus, and as a punishment they had been sent to work for wages at Laomedon's court. Poseidon built the Trojan walls and Apollo watched the Oxes at Mt Ida.When Laomedon refused to pay the two gods, Apollo sent a plague and Poseidon a sea moster to torment the country. An oracle then said that the Gods would be appeased if Laomedon sacrificed his daughter Hesione to the sea serpent.He then asked Heracles to save her, and in return the hero would get his immortal horses. After Hesione had been saved, Laomenon refused to pay Heracles, who killed him after destroying Troy.
