Higino
A fable by Gaius Julius Hyginus is consistent with these vase paintings and was historically attributed to Euripides' play, but modern scholars believe that this too relates to Astydamas' play rather than Euripides'. Per Hyginus, Creon had delegated the task of executing Antigone to his son Haemon, not knowing that they were secretly betrothed. Haemon deceived Creon and spared Antigone, who later bore Haemon a son. The son came to Thebes as an adult, and Creon recognized him, realizing Haemon's deception. Creon refused Heracles' request to pardon Haemon, who then killed Antigone and himself.
