Answer:
The theme represented in this script is the inevitability of fate. It is made clear for the reader through the dialogue between Oedipus and the priest, where they discuss the plague that has befallen Thebes. Oedipus mentions that he understands the terrible fate of Thebes, which foreshadows what is to come. The arrival of Creon and the oracular message emphasizes further the theme of fate. The words spoken by Apollo through the oracle also reveal to the reader that Oedipus is destined to kill his father and marry his mother, therefore fulfilling the prophecy. The audience is left with a sense of foreboding as they realize that Oedipus cannot avoid his destiny, despite his efforts to do so. The theme of fate is reinforced throughout the play, culminating in the tragic end for Oedipus and his family.
