with the sacred enclosure of the Eumenides in the centre. Finally, the Electra of Euripides is altogether exceptional in having its scene laid before a humble country cottage. On the whole, the evidence of the extant tragedies tends to confirm the statement of Vitruvius, and exemplifies the conventional character of Greek tragic scenery. In the great majority of instances the background would be an imposing pile of buildings, adorned with various architectural embellishments. As to the satyric drama, the Cyclops of Euripides is the only specimen of this class of composition which has been preserved. The scene there corresponds exactly to the descriptions of Vitruvius, and consists of a country region, with the cave of Polyphemus in the centre. There can be little doubt that in most satyric dramas the background was of much the same character. As the chorus always consisted of satyrs, whose dwelling was in the forest, the scene of the play would naturally be laid in some deserted country district. The scene in the New Comedy was almost invariably laid in front of an ordinary private house, as is proved by the adaptations of Plautus and Terence. As to the Old Comedy, in six out of the eleven comedies of Aristophanes, the background consists merely of a house, or of houses standing side by side.[575] In four others the principal part of the action takes place before a house. In the Thesmophoriazusae the scene consists of a house and a temple standing side by side. In the Lysistrata there is a private house, and near it the entrance to the Acropolis. In the Acharnians the opening scene takes place in the Pnyx; the rest of the action is carried on before the houses of Dicaeopolis, Euripides, and Lamachus. The scene in the Knights is laid partly before the house of Demos, and partly in the Pnyx. The only comedy in which the scenery is of an altogether exceptional character is the Birds, in which the background consists of a wild country region, filled with rocks, and trees, and bushes. It appears, therefore, that even in the Old Comedy there was not much variety in the scenery.
