The Theban plays consist of three plays: Antigone, Oedipus the King and Oedipus at Colonus. All three plays concern the fate of Thebes during and after the reign of King Oedipus. They have often been published under a single cover. Sophocles, however, wrote the three plays for separate festival competitions, many years apart. Not only are the Theban plays not a true trilogy (three plays presented as a continuous narrative) but they are not even an intentional series and contain some inconsistencies between them. He also wrote other plays having to do with Thebes, such as The Progeny, of which only fragments have survived.
