 As a result, Hippolytus's horses were frightened by a sea monster and dragged their rider to his death.In another version, after Phaedra told Theseus that Hippolytus had raped her, Theseus killed his son, and Phaedra then committed suicide out of guilt, for she had not intended Hippolytus to die.Artemis later told Theseus the truth.
