Oresteia

Thyestes took his brother's wife to bed
and Atreus did not take that news well
he brought the curse of heaven on his head
and doomed his grandson to a living Hell
what could Orestes do in such a plight
he's next of kin and must avenge the king
in his dilemma, no decision's right
the best of actions consequences bring
the  cycle of revenge must be cut short
its logic would thud on in gory rhyme
some goddess must invent a sacred court
to stay the feud before the end of time
Athene contrived a ruse to harness Hate
by delegating justice to the state
