Father.
Biologically, Oedipus real parents are King Laius and Queen Jocasta. Non-biologically, King Polybus and his wife raised Oedipus in the city of Corinth. Luv April4Rain ♥ PS ~ Oedipus was unaware of whom his real parents were, creating the central subject of the story.
Laius was the father of Oedipus who Oedipus killed.
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.
It is after asking Jocasta about Laius' death that Oedipus learns that Polybus is not his father in "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).Specifically, Theban Queen Jocasta and her second husband Oedipus compare notes about her first husband's death. While they await the arrival of the eyewitness to Theban King Laius' murder, the royal couple receive the news that Corinthian King Polybus is dead. The Corinthian messenger subsequently reveals that Polybus and Oedipus are not biologically father and son.
Oedipus killed Laius years ago at the crossroads. He did not know Laius was his biological father and the king of Thebes.
