Theban plays
The Theban plays consist of three plays: Oedipus the King (also called Oedipus Tyrannus or by its Latin title Oedipus Rex), Oedipus at Colonus and Antigone. 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 among them. He also wrote other plays having to do with Thebes, such as the Epigoni, of which only fragments have survived.
Subjects
Each of the plays relates to the tale of the mythological Oedipus, who killed his father and married his mother without knowledge that they were his parents. His family is fated to be doomed for three generations.
In Oedipus the King, Oedipus is the protagonist. Oedipus' infanticide is planned by his parents, Laius and Jocasta, to avert him fulfilling a prophecy; in truth, the servant entrusted with the infanticide passes the infant on through a series of intermediaries to a childless couple, who adopt him not knowing his history. Oedipus eventually learns of the Delphic Oracle's prophecy of him, that he would kill his father and marry his mother; Oedipus attempts to flee his fate without harming his parents (at this point, he does not know that he is adopted). Oedipus meets a man at a crossroads accompanied by servants; Oedipus and the man fought, and Oedipus killed the man. (This man was his father, Laius, not that anyone apart from the gods knew this at the time). He becomes the ruler of Thebes after solving the riddle of the sphinx and in the process, marries the widowed Queen, his mother Jocasta. Thus the stage is set for horror. When the truth comes out, following from another true but confusing prophecy from Delphi, Jocasta commits suicide, Oedipus blinds himself and leaves Thebes, and the children are left to sort out the consequences themselves (which provides the grounds for the later parts of the cycle of plays).
In Oedipus at Colonus, the banished Oedipus and his daughter Antigone arrive at the town of Colonus where they encounter Theseus, King of Athens. Oedipus dies and strife begins between his sons Polyneices and Eteocles.
In Antigone, the protagonist is Oedipus' daughter, Antigone. She is faced with the choice of allowing her brother Polyneices' body to remain unburied, outside the city walls, exposed to the ravages of wild animals, or to bury him and face death. The king of the land, Creon, has forbidden the burial of Polyneices for he was a traitor to the city. Antigone decides to bury his body and face the consequences of her actions. Creon sentences her to death. Eventually, Creon is convinced to free Antigone from her punishment, but his decision comes too late and Antigone commits suicide. Her suicide triggers the suicide of two others close to King Creon: his son, Haemon, who was to wed Antigone, and his wife, Eurydice, who commits suicide after losing her only surviving son.
