The reason which Dörpfeld gives for the lowness of the proscenium—the background, as he calls it—is as follows. He says that such proscenia were first erected at Athens in the fifth century, and were intended to represent an ordinary house of that period. But the ordinary Athenian house of the fifth century was, he asserts, about twelve feet high.[476] To this theory there are several answers. In the first place, as we have seen, some proscenia were only about eight or nine feet in height; which is far lower than any ordinary Greek house, either at Athens or elsewhere. In the second place there is no clear evidence to show that the Athenian house of the fifth century was twelve feet high. From the remains lately discovered at Delos it appears that in the better class of houses there even the first story was more than twelve feet.[477] But granting, for the sake of argument, that an Athenian house of the fifth century was of the size which Dörpfeld supposes, it is difficult to see what this has got to do with the height of the scenic background. The Athenian theatre, we should remember, was developed originally as a place for tragedy rather than as a place for comedy. The background therefore must have been intended to represent, in most cases, a palace or a temple. But why should this palace or temple have been made the same height as an ordinary house? Moreover, the proportions must have appeared extraordinary. A structure about fifty feet long, and twelve feet high, would be altogether unlike any palace or temple. Dörpfeld replies to this that it is impossible on the stage to represent buildings as large as they really are; that in modern scene-paintings the representations of palaces and temples are much reduced in size as compared with the originals.[478] This is quite true. But they are reduced to scale, and in a proper proportion. A modern scene-painter, in representing St. Paul’s, would no doubt have to make his representation much smaller than the actual St. Paul’s. But in diminishing the height he would diminish the width at the same time. No modern scene-painter would produce a temple fifty feet long and twelve feet high; nor can we suppose that the ancients would have put up with a similar disproportion.
