Aeson in Jason: Later Adventures and Death
Aeson, King of Iolcus, is most famous for being the father of his famous son, Jason. He gets kicked off his throne by his half-brother, Pelias, and spends most of his time in a dungeon, where he grows old and decrepit. In some versions of the story, he kills himself while Jason is on his quest, while in others we see him made young again by Medea. We choose to believe that the latter is true. Hey, it's pretty much the only happy thing that happens in Jason's later years. Can't at least one person have a happy ending?
