Yes, Theban King Laius is Theban King Oedipus' rival. The life of the one demands the death of the other. The two meet at a crossroads between Delphi and Thebes. Neither one knows that their relationship is father to son. Yet each one knows that the father is fated to be killed by the son.
Despite the fate, Laius becomes Oedipus' rival over the right of way. He asserts his right by striking a stranger who's young enough to be his son and whom he resembles. In response, Oedipus kills a stranger who's old enough to be his father and whom he resembles.
Laius was the father of Oedipus who Oedipus killed.
Creon is Jocasta's brother.
Tiresias tells Oedipus he is the murderer of Laius.
Oedipus does not realize that he killed king Laius and that king Laius was his father.
Laius was father of Oedipus by Jocasta and the son of king Labdacus of Thebes.
At the time of Laius's murder, Oedipus was not king of Thebes; in fact he unknowingly killed Laius and was the son of Laius.
Oedipus did, but he didn't realize it was Laius. Also, no one knew it was Oedipus until towards the end.
Oedipus
The blind prophet Tiresias who is called by Oedipus to reveal who killed King Laius. When he is hesitant to do so however as the killer is Oedipus, Oedipus jumpsto conclusions assuming that it is he Tiresias who murdered Laius.
Oedipus kills him.
Oedipus killed Laius years ago at the crossroads. He did not know Laius was his biological father and the king of Thebes.
That Laius strikes the first blow, that it is donein an insulting manner and that it really hurts is why Oedipus strikes back in self-defense in "Oedipus Rex" by Sophocles (495 B.C.E. -- 405 B.C.E.).Specifically, Oedipus is traveling from Delphi to Thebes. Laius is traveling from Thebes to Delphi. The two meet at a crossroads in Phocis, and Oedipus has the right-of-way, which Laius refuses to respect. Laius hits Oedipus really hard on top of the head, and Oedipus' retaliation is powerful enough to kill Laius.
