Anthos (play)
Anthos or Antheus is a play by the 5th century BCE Athenian dramatist Agathon. The play has been lost. The play is mentioned by Aristotle in his Poetics as an example of a tragedy with a plot which gives pleasure despite the incidents and characters being entirely made up. Anthos is the only known Greek tragedy play whose plot was entirely invented by the poet. Other 5th century tragedies were based on myth, or less frequently on actual history.
The play's plot is not clear; H. J. Rose claimed that Parthenius of Nicaea sourced the story of Antheus and Cleoboea from this Anthos, a typical Potiphar's wife tale where Antheus rejects the married Cleoboea's amorous advances, and she in revenge kills him by throwing a boulder on him after convincing him to go down into a well.
