We have now followed the development of the stage-buildings from the old wooden erections of the fifth century to the more solid and elaborate structures of the Hellenistic period. All that remains is to trace their history during the later ages of Roman supremacy. We have shown that at Athens the stage-buildings were practically reconstructed after the Roman fashion in the time of Nero. The same tendency had already become prevalent in other places at a much earlier period. After the middle of the first century B.C. most of the new theatres built by the Greeks were constructed in the Roman style. The majority of the old ones began about the same time to be altered and modified under Roman influence. This latter process, however, was never carried out universally. It was confined mainly to the more outlying parts of the Hellenic world, such as Sicily and Asia Minor. In Greece proper it was a comparatively rare occurrence. Athens and Argos are the only cities on the Greek mainland which are known to have Romanized their theatres. Still, looking at the Greek world as a whole, it may be said that from the time of the Christian era the great majority of Hellenic theatres were adapted to the Roman model. It was at this period that the stage-buildings began to be constructed on a more lofty scale, and their front adorned with the gorgeous architectural embellishments which we have previously described. Some idea of their magnificence may be obtained from the existing remains, and especially from those of the theatre at Aspendos, which is well preserved. A restoration of part of the interior of this theatre (Fig. 10) is here inserted.[446] The back-wall erected at Athens in the time of Nero was of the same type, though smaller in size. Façades of this imposing character may perhaps be thought too elaborate for the back-wall of a theatre. When dramas were being performed, and they were covered with painted scenery, their architectural beauty would be concealed from the eyes of the spectators. But ancient theatres were regularly used, not only for dramatic performances, but also for various other purposes, both artistic and political. On such occasions, when the stage was without scenic decoration, the architectural grandeur of the back-wall would add greatly to the beauty of the stage-buildings, and form a pleasing object to the eye. Probably, too, at many of the dramatic exhibitions, when the action was laid before a temple or palace, painted scenery was dispensed with, and the architectural façade supplied an appropriate background.
