He loved his mother

Jocasta bade her husband come to bed
and toss aside  his burdens 'til the morn.
Let sextons wash and bury the plague's dead;
gravedigging's not for one so noble born.
Teiresias advised him toss aside
rash vows to nail his predecessor's bane.
And not to look too closely at his bride
but grew defensive rather than explain.
His parents tossed their child out, long ago
but Fate's decrees are not so lightly ducked.
Unknowingly, he'd laid his father low;
The queen discovers she's been doubly fucked.
He fled from Corinth to evade this thing
but Thebes was destined for its sightless king.
