About Anthos

Anthos or Antheus is a play by the 5th-century BCE Athenian dramatist Agathon. The play has been lost in its entirety. The play is mentioned by Aristotle in his Poetics (1451b) as an example of a tragedy with a plot which gives pleasure despite the incidents and characters being entirely made up. Anthos is thus the only known Greek tragedy play whose plot was entirely invented by the poet. Other 5th-century tragedies were based on myths, or less frequently on actual history.
