King on Crete who was Deucalion's son and Minos's grandson. He was one of Helen's suitors and fought bravely with the Greeks in the Trojan War. On his journey back from the war a storm threatened to sink his fleet, and he promised Poseidon to make the first living thing he met at home a sacrifice to the god if he would only return safely. Since it was his son who first greeted him, Idomeneus denied Poseidon his sacrifice, and so Crete was stuck with plague. Idomeneus people then exiled their king, who ended his days in Calabria in Asia Minor, where he built a temple to Athena.
