Answer:
Oedipus ran to Thebes to prevent the oracle from happening.
Step-by-step explanation:
When Oedipus was called a child with no father by some person, he became determined to learn about his origin. This led to his sojourn to the oracle of Apollo. At the oracle, Oedipus was told that he would kill his father and sleep with his mother.
To prevent the prophecy from coming true, Oedipus went to Thebes and on his way he killed a man named Laius who unbeknownst to him was his father. He married his mother, Jocasta, the queen and widow of Thebes who bore him four children. In that way, he fulfilled the prophecy.
