This is from the story of Oedipus, in which the prophecy is that the son of the king will kill his father and marry his mother.
The oracle told Queen Jocasta and King Laius of Thebes while she was heavily pregnant with Oedipus, that the child was destined to kill his father.
He was born in Thebes, the son of Laius, King of Thebes, and Queen Jocasta
King Lauis, and Queen Jocasta of Thebes.
An oracle had a prophecy that Oedipus would kill his father, king of Thebes, and marry his mother.
His birth parents are the king and queen of Thebes, King Laius and Queen Jacosta. His adopted parents (who he thought were his real parents) are the king and queen of Corinth, King Polybus and Queen Merope.
The plague would be lifted when the murderer of old king Laius was found.
he wanted the people to drive out the killer of the former king
Laius and Jocasta are king and queen of Thebes at the time of Oedipus' birth in "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).Specifically, Jocasta is not a king's daughter. But she becomes queen as a direct descendant of Thebes' founding King Cadmus and through her marriage to her cousin Laius. Laius is king because he too is descended from Cadmus and because he is Theban King Labdacus' son.
Creon returns with a message from the oracle: the plague will end when the murderer of Laius, former king of Thebes, is caught and expelled; the murderer is within the city.
Her father is Oedipus, who is the son of Jocasta and Laius, the king and queen of Thebes.
The Queen of Thebes and mother of Oedipus is Jocasta. She unknowingly married her own son, Oedipus, fulfilling a prophecy that was foretold to her husband, King Laius. Upon learning the truth, Jocasta tragically takes her own life.
Theban King Oedipus fears Corinthian King Polybus because of the prophecy of the Delphic Oracle. The Oracle identifies Oedipus' fate as the unenviable one of killing his own father and marrying his own mother. Oedipus is afraid that he somehow will end up a father and king killer if he remains in Polybus' presence. So he flees what he thinks is his hometown of Corinth and tries to start life afresh in Thebes. But unbeknownst to him, Oedipus actually is a hometown boy of Thebes. Additionally, he actually is the son of Theban King Laius, whom he kills in self defense; and of Theban Queen Jocasta, whom he unknowingly marries as the reward for ridding Thebes of the Sphinx.
