By Cleopatra,[2][3] Deucalion fathered Idomeneus who succeeded him and led the kingdom into the Trojan War.
[4] In Diodorus' account, Deucalion and Molus were brothers and their sons Idomeneus and Meriones led the Cretans to Troy.
It is said that when Theseus was about to leave Crete, he joined battle with the Cretans at the gate of the Labyrinth where he slew Deucalion and his bodyguard.
One source recounts a different relationship between Deucalion and Theseus: Odysseus pretends to be his second son Aethon when he speaks to his wife while in disguise.
It is unclear whether Aethon is a real son of Deucalion, left by Idomeneus to act as regent during the war, or invented by Odysseus.
