In Homer, Oedipus lives, dies, and is buried in Thebes. But post-Homeric legend, under the influence of the pollution doctrine, could not accept these facts. Even if the plea of quasi-involuntary homicide which Oedipus himself put forward had been accepted he would still have had to go into exile for at least a period of years, and even then he could not have returned to his domestic religion or have been buried in the tomb of his fathers. The duration of exile for extenuated or involuntary slaying in historical times, and therefore presumably[183] in the pollution era, depended on the will of the relatives of the slain. One single objector could have extended the exile period indefinitely, at least in theory, according to the law ‘let all consent to be appeased or let one objector hold the field.’[184] But in the post-Homeric story of Oedipus, as Sophocles gives it, the plea of Oedipus was not accepted. He was regarded as a voluntary homicide and sent into exile. It is true that when Polyneices himself was banished, for political reasons, from Thebes, he naturally relented, and in his altered mood he offered to restore Oedipus to his home.[185] But in order to restore Oedipus it was necessary that Kreon and Eteocles should be either killed or exiled, and this contingency had not been realised. In Euripides the unhappy king ultimately suffers the same fate. Kreon says to Oedipus[186]:
But to my words, O Oedipus, attend:
Eteocles, thy son, hath to these hands
Consigned the sceptre of the Theban realm, ...
I for this cause no longer can allow thee
Here to reside: for in the clearest terms
Teiresias has pronounced that, while thou dwell’st
In these domains, Thebes never can be blest.
Therefore depart. Nor through a wanton pride,
Nor any hate I bear thee, do I hold
