background
As is the case in most climactic drama, much of what constitutes the myth of Oedipus takes place before the opening scene of the play. In his youth,Laius was a guest of King Pelops of Elis, and became the tutor ofChrysippus, youngest of the king's sons, in chariot racing. He then violated the sacred laws of hospitality by abducting and raping Chrysippus, who according to some versions, killed himself in shame. This murder cast a doom over Laius, his son Oedipus, and all of his other descendants. However, most scholars are in agreement that the seduction or rape of Chrysippus was a late addition to the Theban myth.
A son is born to King Laius and Queen Jocasta of Thebes. After Laius learns from an oracle that "he is doomed/To perish by the hand of his own son", he tightly binds the feet of the infant together with a pin and orders Jocasta to kill the infant. Hesitant to do so, she orders a servant to commit the act for her. Instead, the servant takes the baby to a mountain top to die from exposure. A shepherd rescues the infant and names him Oedipus (or "swollen feet"). (The servant directly hands the infant to the shepherd in most versions.) The shepherd carries the baby with him to Corinth, where Oedipus is taken in and raised in the court of the childless King Polybus of Corinth as if he were his own.
