 Theseus is disappointed to learn, however, that Hippolytus has taken a vow of chastity as part of his devotion to the god of medicine and that he is not interested in being the heir of Theseus to the throne of Athens.Theseus therefore reluctantly decides that his less kingly son by Phaedra, Akamas, should come to Athens to begin to learn how to be king.Theseus is not eager to include Phaedra, who is living in Crete, but decides that he might dishonor her if he did not invite her to Athens.
