Oedipus (or Odipus, sometimes spelled Oidipous) is a typical tragic figure of fate in the history of European literature. He was the son of King Laius and Queen Jocasta of Thebe in Greek mythology, who unknowingly killed his father and married his mother. Homer, the master of dramatic art, and Sophocles, the master of tragic fate, enriched his tragic fate in the ancient Greek drama "King Oedipus".

Origin of Curse
Laios was the son of King Rabdakos of Thebes. He lost his father in his youth, and his guardian was killed by political enemies, deprived of all power as King of Thebes. Later, he defected to Pelops and worked as a governess for Pelops' son, Chrysippus. But Laius fell in love with the beautiful young man Chrysippus, abducted him and caused his death.
Peropus believed that Laius betrayed and killed his own son, so he cursed Laius with the curse of being killed by his own son.
Subsequently, Laius became the King of Thebes and married Iocaste, which was once again confirmed by the curse from Pelopos - the oracle of 'to be killed by his son'. Laios, who was deeply afraid of this prophecy and oracle, had been avoiding intercourse with his wife Iocaste in order to avoid the birth of his offspring.

Growth experience
After getting drunk one day, Laios had a night of sexual intercourse with his wife Iocaste, which led to the birth of the protagonist Oedipus. That is to say, Iocaste's pregnancy was the result of a male partner's unwilling sexual intercourse, while Oedipus passed away on the premise of violating the will of his father, Laius.
Laios threw the newborn baby into the barren mountains of Catalon, with the apparent intention of killing his son, whom he had not named after him. He just didn't do it himself, but abandoned the baby in an environment where it couldn't survive alone and caused it to naturally die.
But the baby was rescued by the shepherd and named "swollen feet" due to the injured feet, known as Oedipus.
Subsequently, Oedipus became the adopted son of King Polibos and Queen Melobe, who had no descendants in the neighboring country of Thebes, the Kingdom of Corinthus. Raised as a biological son in the palace and designated as the heir to the throne.
After Oedipus grew up, he left Corinth and swore never to return, knowing that the king and queen of Corinth were not his biological parents, because the oracle in the Delphi temple said he would kill his father and marry his mother.

The oracle fulfilled
At this moment, in the city of Thebes, in order to punish the crimes committed by Laius against Chrysippas, the Queen of the Greek Divine Realm, Hera, brought the sphinx, the female demon with a lion's body and human face, and the whole city was in extreme panic. As is well known, Sphinx asked passersby to answer the riddle "What are animals that walk on four feet in the morning, two feet in the afternoon, and three feet in the evening. No one could solve the riddle, so she devoured the citizens of Thebes.
King Laius of Thebes hoped to find a way to repel Sphinx through the oracle, and on his way to the Temple of Delphi, he met Oedipus, who was walking towards the city of Thebes. Because the narrow road could only accommodate one person, and the two people did not know each other, King Laius roughly ordered Oedipus to make way. Oedipus was furious and fought with Laius, ultimately killing him. Of course, he didn't know that he had killed his own father.
After Oedipus entered the city of Thebes, he solved the riddle of Sphinx. The answer to the riddle was human, with morning=infancy (crawling), noon=youth (walking), and evening=old age (using a cane), causing the banshee to commit suicide in shame.
Oedipus, who saved the city of Thebes, was revered by the people and elected as the king. According to custom, he married the queen Iocaste, who had lost her husband Laius, and also fulfilled his oracle to "kill his father and marry his mother".
Oedipus and his mother Iocaste gave birth to two sons named Polynychus and Eteocles, as well as two daughters named Antigone and Ismene.
Due to Oedipus' unwittingly committing the great crime of "killing his father and marrying his mother," the plague and famine descended on the city of Thebes. Later, the countries ruled by Oedipus experienced constant disasters and plagues. While searching for the cause of the disaster, King Oedipus sought guidance from the gods to understand why the disaster had occurred. Finally, under the revelation of the prophet Teiresias, Oedipus realized that he was the son of Laios, and ultimately fulfilled his unfortunate fate of killing his father and marrying his mother.

Shocked, Iocaste hung himself in shame, while Oedipus, equally indignant, cursed himself for seeing such a scene in his eyes. He blinded himself with a brooch and walked up to the citizens to admit that he was the murderer of his father, the husband who married his mother, a villain cursed by the gods, and a demon of the earth.
But the Thebes did not despise the king they had once loved and respected. But he was unwilling to forgive himself and chose to leave the country after building a tomb for his unfortunate mother. He said that he should have been burned to death on the mountaintop of Catalon, where his parents abandoned him. Whether it's life or death, it's all up to God. Oedipus' eldest son Eteocles inherited the throne after his departure, while his second son Polynychus and his brother sacrificed their lives in the struggle for the throne. In the end, their uncle Kryon, the brother of Iocaste, became king.
Afterwards, Oedipus drifted around under the guidance of Antigone, and was later protected by Theseus, who had repelled the monster Minotaurus. He ultimately died in the holy land of the goddesses.
