Idas (son of Aphareus)

[9] Poseidon consented to his use of the chariot, and Idas stole Marpessa away from a band of dancers and fled to Pleuron in Aetolia.

[10] Her father, after chasing the couple for a long time and realizing he could not catch up to them, killed his horses and then drowned himself in a nearby river Lycormas and became immortal.

[12]As the two fought for the girl's hand, Zeus eventually intervened and commanded Marpessa to choose between her mortal lover and the god.

Trying to recover their lost brides-to-be, the two Messenian princes, took to arms and joined the celebrated fight between them and their rival suitors.

When they reported this to Pollux, he rushed up and overcame Idas in a single fight, recovered the body of his brother, and buried it.

In revenge, the divine father of Pollux, Zeus, smote Idas with a thunderbolt and carried up his son to the heavens above where he shared his immortality with his mortal brother.

[18] On their journey to fetch the Golden Fleece, Idas avenged the death of Idmon, son of Apollo by slaying the wild boar that wounded and killed the seer.
