"Minos’ sons, they say, were Deucalion and Molus, and to Deucalion was born Idomeneus and to Molus was born Meriones. These two joined with Agamemnon in the expedition against Ilium with ninety ships..."[5]
Mythology
Theseus in Crete
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.
"And when Deucalion, his son [i.e. Minos], who was on hostile terms with the Athenians, sent to them a demand that they deliver up Daedalus to him, and threatened, if they refused, to put to death the youth whom Minos had received from them as hostages, Theseus made him a gentle reply, declining to surrender Daedalus, who was his kinsman and cousin.." "Then joining battle with them at the gate of the Labyrinth, he [i.e. Theseus] slew Deucalion and his body-guard.[6]
One source recounts a different relationship between Deucalion and Theseus:
While he [i.e. Deucalion] was ruler of Crete, formed an alliance with the Athenians and united his own sister Phaedra in marriage to Theseus.[5]
Odysseus' lie
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.
Notes
^Hyginus, Fabulae14 &
173, this was probably a misinterpretation of the author of a passage by
Valerius in his Argonautica 1.367: "...and from the sandy shores of Pella
Deucalion of the unerring javelin, and
Amphion renowned in the close fight, whom
Hypso at one birth brought forth...", this Deucalion was also called
Asterius in earlier myths like in
Apollonius of Rhodes, Argonautica 1.176: "... Asterius and Amphion, sons of
Hyperasius, came from Achaean Pellene...". This makes sense that this Deucalion who was killed by Theseus was never been encountered by the hero before his exploit in Crete.
