In the play "Oedipus Rex," by Sophocles (rpt. Place Literature: A reader for Freshman Composition ll, 2nd ed. [Boston: Pearson, 2012] 120-166) the Oracles had prophesied that Oedipus would kill his father and beget children by his mother. By the end of this terrific play the prophecy had become true and everyone knew it. But, the main arguing point is to decide whether or not Oedipus was the puppet of fate or the creator of his own fate. But what it really is conveyed as is a combination of both throughout the play.
As a baby, Oedipus' mother and father sent him away with a shepherd to put Oedipus in the mountains to die. This was all because they received a prophecy from the Oracles stating that their son will kill its father and beget children by his mother. But, when being brought into the mountains by the shepherd, the shepherd ran into a shepherd from another place called Corinth and gave the baby to him to bring back to Corinth as he could not let a little baby suffer like that. So, the shepherd of Corinth took the baby back to land and gave it to the king and queen to have as a child because they did not have one and wanted one for some time.
As time went on, Oedipus grew older and was out one night and heard a drunken man say that there was a prophecy saying that he was to kill his father and beget children by his mother. Oedipus obviously believed that the king and queen of Corinth were his real parents and so he did what he could do to not let the prophecy become true, he ran as far away from Corinth as he could. Oedipus heard this statement because it was all part of the plan to send him running away. Oedipus was being controlled by a greater force. But, little did he know he was going to encounter things to make the prophecy become true. Oedipus was sent in this way of direction by being a puppet of fate.
Oedipus was also the creator of his own fate because while running away from Corinth he came to a split road where he ran into a man in a carriage and men guarding around him.
