Sophocles's play "Oedipus Tyrannus," perhaps more commonly known as "Oedipus Rex" or "Oedipus the King," is a notable play which has been read and performed continuously since its writing in 429 B.C. One of the major reasons for this continued consumption of such an old text is its representation of dramatic concepts. Oedipus Tyrannus is both a classic example of a tragedy with an instantly recognizable tragic hero as well as an example of a play with a definite dramatic structure. The stasis of Oedipus Tyrannus begins with the city of Thebes been thrust into plague. Theban king, Oedipus, is willing to do anything to end the sickness that has been cast upon his city. In typical Greek fashion, he sends his brother-in-law, Creon, to consult the oracle of Delphi for advice from the gods. Creon's return from the oracle marks as the intrusion when he brings news that the plague will end when the murderer of Laius is caught. This scene signifies the intrusion because this information is what sets the entire plot of the play into motion. This also acts as the source of the main, external conflict because it gives Oedipus an outer purpose and something external to strive for. The moment of engagement comes from after Oedipus learns from Creon that Laius was killed by a group of thieves and Oedipus launches himself into action to find the murderer. The events of the rising action begin quickly after. The first major event of the rising action comes from when Oedipus sends for the blind prophet Tiresias who, after much threatening and accusations from Oedipus, reveals that Oedipus is the murderer. Before Tiresias leaves the stage, he makes a prophecy saying that the murderer of Laius will turn out to be both father and brother to his own children, and the son of his own wife. This is the second act of the rising action. The third event comes about when Oedipus's wife Jocasta enters and tells Oedipus that Laius was killed a three way crossroads
