Jocasta and Laius has a baby ( Oedipus ). Jocasta wanted to keep her baby but Laius wanted to take the baby to the woods and leave him for the wolves to feast on. The prophecy said that the baby would grow up to kill his father and take place as king , and marry his mother. A Shepard found this baby in the woods and soon adopted him as his own.
When Oedipus grew up , he found himself in a argument with Laius because he was in his way , not knowing this man was his father , he carelessly killed him , had 4 kids and married the woman who he would soon figure out is his mother.
Antigone , still grieving buried her
At this point , the jig is up ! This family is now dealing with the horrible tragedy of finding out the incest running through the family. It became a burden. Oedipus decided to puncture both of his eyes. His 2 sons fought to the death over their fathers position as king. This was just too much for Jocasta to handle ,
