The last few years have been prolific in new theories on the subject of the stage. Most of them may be regarded as developments or modifications of Dörpfeld’s views. Before leaving this subject it may be well to give a brief account of the more important of them. Bethe considers that there can no longer be any doubt as to the existence of the Hellenistic stage. He also agrees that the passages in Aristophanes prove the use of a low stage at the time when Aristophanes wrote. But for the greater part of the fifth century he denies its existence. He considers that the first Greek stage was erected in 427 or in 426, and that this date was an important epoch in the development of the theatre. He founds his belief on the fact that after this date there is no further instance of the use of the ekkyklema, while before this date there is no example of the use of the mechane, the theologeion, and the drop-scene.[534] But, in the first place, it is by no means clear why the presence or absence of these contrivances should involve the existence or non-existence of a stage. In the second place, his dates are open to question. There is no proof, as we shall see later on, that the machinery which he mentions was introduced or discontinued at the time specified. Another theory has been put forward by Weissmann. He, too, accepts the Hellenistic stage, but agrees with Dörpfeld that in the fifth century actors and chorus performed on the same level. However, he thinks that the passages in which old men complain of the steepness of the road prove that there must have been a raised platform which they had to ascend. As one of these passages—that in the Hercules Furens—is spoken by the chorus, he comes to the conclusion that there was a large platform for actors and chorus combined. This platform extended from the back-scene over a considerable part of the orchestra, and on it stood the actors and chorus, both on the same level.[535] To this it may be answered, that the evidence on which he relies is far too slight a justification for such a sweeping hypothesis. Also on general grounds it is inconceivable that the Greeks, when they already possessed an orchestra which was admirably adapted for choral performances, should have taken the trouble to erect a huge platform on the top of it. Christ agrees in the main with Weissmann. He accepts the Hellenistic stage for the later period, and also the platform for the chorus in the orchestra during the fifth century. But he thinks the passages in Aristophanes prove that the actors even then stood higher than the chorus. He therefore supposes two stages: one immediately before the back-scene, for the actors; and another larger and lower one in the orchestra, for the use of the chorus.[536] He thus eventually comes round to the same conclusion as Wieseler, though by a very different process. His theory, however, is open to the same objections as that of Weissmann. This orchestral platform is utterly improbable in itself, and
