dead, and that Oedipus is called back to Corinth to be King.

Oedipus is both
happy and grieved to learn that Polybus is dead. He's grieved because he believes that Polybus
is his father, and he mourns his father's death.

Oedipus is also happy and
relieved to learn that Polybus died of natural causes because Oedipus has escaped the fate that
the Oracle had prophesied for him: that he would kill his own father.

However, Oedipus is still anxious about returning to Corinth. His mother, Merope, the
wife of Polybus, is still alive, and the Oracle also prophesied that Oedipus would marry his
mother.

Hoping to allay Oedipus's fears, the Messenger reveals to Oedipus
that he is not the son of Polybus and Merope, but that he himself gave Oedipus to Polybus and
Merope as a baby.

The Messenger tells Oedipus that long ago he was a shepherd
tending his flock in the mountains when another shepherd who worked for Laius, the former King
of Thebes, gave Oedipus to him to care for him.

Oedipus's wife, , advises
Oedipus to leave the matter alone and not inquire further about it, but Oedipus sends for the
other shepherd to hear his story.

In episode 4, the oldis brought to Oedipus,
and he reluctantly tells the story of how he was commanded by King Laius's wife to take Oedipus
into the mountains to let him die there in order to avoid the Oracle's prophesy.

But the Herdsman took pity on Oedipus, and instead of leaving him in the mountains to
die, he gave Oedipus to another shepherd (now the messenger) to raise.

The
messenger took the baby back to Corinth, where he was adopted and raised by Polybus, his foster
father, and Merope, his foster mother.
