From whom did the messenger from Corinth receive the baby Oedipus?

The messenger from Corinth received the baby Oedipus from a shepherd. This shepherd played a crucial role in the backstory of Oedipus’s life. He was the one who found the infant Oedipus abandoned on the mountainside, where his biological parents had left him to prevent the fulfillment of a prophecy that foretold Oedipus would kill his father and marry his mother. The shepherd's decision to save the child and give him to the messenger ultimately set off the chain of events that led to the tragic unfolding of Oedipus’s fate.

This connection emphasizes the themes of fate and free will in the play, portraying how a simple act of kindness by the shepherd inadvertently contributed to Oedipus's tragic destiny. The other choices do not accurately reflect the source of the baby Oedipus in the myth; it was specifically the shepherd's actions that held significant importance in the narrative.
