Short answers, pulled from the story.
Oedipus was born to King Laius and Queen Jocasta of Thebes. He was given up as an infant to avoid a prophecy and was raised by King Polybus and Queen Merope of Corinth, who adopted him as their own.
The Sphinx asked: "What walks on four feet in the morning, two in the afternoon, and three at night?" Oedipus answered that it was man, who crawls on all fours as an infant, walks on two legs as an adult, and uses a walking stick in old age. He was the first to answer correctly.
The three Theban plays by Sophocles are Oedipus Rex, Oedipus at Colonus, and Antigone. They were written for separate festival competitions many years apart and were not originally intended as a continuous trilogy.
In Sophocles's version, Oedipus blinded himself after discovering that Jocasta had hanged herself and that all the prophecies had been fulfilled. He used the pin from a brooch he tore off Jocasta's gown to blind himself. The blinding does not appear in sources earlier than Aeschylus.
Sigmund Freud used the name of the myth to define the Oedipus complex, describing a male child's unconscious desire for the exclusive love of his mother alongside jealousy toward and an unconscious wish for the death of his father. Freud argued the myth's persistent retelling reflected a shared cultural preoccupation with these themes.
Oedipus's sons Eteocles and Polynices killed each other in battle over the throne of Thebes. Creon then forbade the burial of Polynices. Antigone defied that order, and in Sophocles's Antigone she hanged herself after being placed in a stone cavern as punishment, which also led to the deaths of Creon's son Haemon and wife Eurydice.
