A further point in Puchstein’s theory concerns the height of the stage in the building which he assigns to the fifth century.[442] The only possible purpose of the deep side-wings was to enclose a stage. The analogy of later theatres of the same type, such as those of Tyndaris and Segesta, where traces of the stage still remain, render any other conclusion indefensible. No other hypothesis has any support from any monuments whatever. This stage may have been of wood, proscenium and all, and this would account for its disappearance; or it may have had slight stone supports, which might easily have left no trace. The height of this old stage at Athens may be determined approximately by a comparison with the almost contemporary stage-buildings at Eretria, where there is evidence to show that the stage must have been not less than nine or ten feet from the ground. But this does not mean that still earlier the stage was not, as previously contended,[443] a comparatively low one, such as would be suitable for the plays of Aeschylus and the earlier plays of Aristophanes. Nor is the existence of a high stage about 400 B.C. inconsistent with the presence of a chorus, as Dörpfeld thinks.[444] The decision depends not on the presence of a chorus, but on the intimacy of the connexion between the chorus and the actors. As long as they freely commingled together, the stage must have been moderately low. But when the chorus ceased to take any active part in the play, the raising of the stage would do no harm, and would be an advantage, as giving the audience a better view of the actors. Now it was precisely towards the end of the fifth century that the chorus began to lose its old significance, and to assume the functions of mere singers of interludes.[445] Hence there would be nothing surprising if it were proved, and not merely rendered likely, as by Puchstein, that at this date the stage began to be of a greater height than formerly. § 10. _The Stage-buildings in Roman Times._
