Oedipus the King (Jocasta)

Jocasta says

Then thou mayest ease thy conscience on that score.
Listen and I’ll convince thee that no man
Hath scot or lot in the prophetic art.
Here is the proof in brief. An oracle
Once came to Laius (I will not say
‘Twas from the Delphic god himself, but from
His ministers) declaring he was doomed
To perish the hand of his own son,
A child that should be born to him me.
Now Laius -so at least report affirmed –
Was murdered on a day highwaymen,
No natives, at a spot where three roads meet.
As for the child, it was but three days old,
When Laius, its ankles pierced and pinned
Together, gave it to be cast away
others on the trackless mountain side.
So then Apollo brought it not to pass
The child should be his father’s murderer,
Or the dread terror find accomplishment,
And Laius be slain his own son.
Such was the prophet’s horoscope. O king,
Regard it not. Whate’er the god deems fit
To search, himself unaided will reveal.
