What to read after Women of Trachis?

The least developed of all Sophocles' tragedies in terms of structure and action, Women of Trachis dramatizes the unfortunate and accidental death of Ancient Greece’s greatest hero, Heracles. The play is set before the royal palace at Trachis, fifteen months since the region’s king, Heracles, has left his home to go on one of his adventures. His queen, Deianira, is worried due to the lack of news, so she sends her son Hyllus to find out what has become of Heracles. Hyllus, however, already knows this much: after serving as a slave for a year at the court of queen Omphale, Heracles is currently fighting in Oechalia against King Eurytas, the author of his previous demise. Determined to help him, Hyllus leaves for Oechalia. Soon after, Heracles' herald Lichas arrives at the court of Trachis with a few female captives, one of whom is none other than Iole, King Eurytas' daughter. After some inquiring, Deianira learns from Lichas that Heracles has conquered Oechalia not because of Eurytas’ offense, but because he wanted the country’s princess for himself. Disheartened, Deianira sends Heracles a festal robe anointed with the blood of the centaur Nessus, who had told her, years before and with his dying breath, that his blood is a love charm which has such power to make Heracles never look upon any other woman. That is precisely what happens, but not in line with Deianira’s expectations. Namely, as Hyllus soon reports, the robe has poisoned Heracles, and he is in such pain and agony that he is better off dead. Upon realizing what she has done, Deianira kills herself. After being brought home to Trachis, Heracles asks his son Hyllus to marry Iole and then orders him to light a funeral pyre that will put an end to his suffering.
