What are the motifs in The Frogs, and Other Plays. Translated with an Introd. by David Barrett by Aristophanes?

Poetry in society is a recurring idea. Most, if not all, of Aristophanes' comedies have a political point. This is partially because Aristophanes was deeply concerned with the direction of his city, especially under the rule of Cleon. When he is not directly railing against Cleon in his plays, he is attacking the war that Cleon is continuing. For that reason, Aristophanes is concerned not only with politics as such but also with the role o f poetry and drama in relation to politics. In the Frogs, Dionysus, standing at least partially in for Aristophanes himself begins by favoring Euripides because of his art but ends up favoring Aeschylus because of his political value. This leads us to suspect that Aristophanes believes poetry has a dual purpose in society.
