 In addition to Frogs with its face-off between Aeschylus and Euripides there is Women Celebrating the Thesmophoria, which calls mimêsis a disruption of life and opposes it to nature. It can also be argued that Women Celebrating the Thesmophoria finds an ambiguity in dramatic imitation that anticipates Plato; for in that play, as in the Republic, mimêsis combines composition and performance, the invention of characters and the portrayal of them (Pappas 1999).
