None of his plays survive intact, but the titles of thirty of them are known, including a Hyperbolus (c. 420–416 BC), Victories (after 421), Cleophon (in 405), and Phaon (probably in 391).
In 410 BC, one of his plays took first prize at the City Dionysia.
Phaon included a scene (quoted in the Deipnosophistae of Athenaeus) in which a character sits down to study a poem about gastronomy (in fact mostly about aphrodisiacs) and reads some of it aloud: "In ashes first your onions roast, Till they are brown as toast, Then with sauce and gravy cover; Eat them, you'll be strong all over."
It has been suggested by Ida Soldini that, contrary to the persuasion of contemporary scholars, Plato the comic poet and Plato the philosopher, the founder of the old Athenian Academy could very well be one and the same person.
Of Plato's plays only the following thirty titles have come down to us, along with 292 associated fragments.
