What is the setting of The Frogs, and Other Plays. Translated with an Introd. by David Barrett by Aristophanes?

The settings of these three plays vary dramatically. Wasps take place in Athens in and around the house of Philocleon. Mention is made of several other Athenian landmarks and there is also mention of a party at another person's house, though, the play only recounts the action from those places rather than actually showing us the action. This is no doubt due to some of the logistical restraints of the time, but it is worth noting that according to the standards of tragedy at the time, a play should take place in a uniform location over the course of one day. The play itself should only take place during the time that the actual play takes place. Of course, this is not true for all of Aristophanes' comedies, notably the Frogs. It takes place in several locations, namely Hades, the house of Heracles and on the river Styx. The Poet and the Women also takes place in several locations. It starts outside of Agathon's house and then moves to the Temple of Demeter. It is clear then that Aristophanes has no qualms about switching locales is the play demands it. His locations are never exotic for their own sake, however, and follow the necessity of the drama. Of course, Hades is an exiting setting and in Frogs, the location itself adds something to the themes of the play. This is primarily true only of Frogs, though, as the other settings are pretty prosaic.
