(i) The evidence of the extant dramas. This, already adduced by many to prove that a stage was used, is taken by Dörpfeld[163] as “showing unmistakably that no separation existed between chorus and actors, that on the contrary both played on the same area”. He refers to action where people pass between house and orchestra with no apparent difficulty or hesitation. The chorus enter from the “palace” in the _Choephorœ_, the _Eumenides_, and Euripides’ _Phaethon_; the chorus of huntsmen enter it in the _Hippolytus_. There are other probable or possible instances. Particularly noteworthy is the fact that in _Helena_ the chorus in the midst of the play enter the building, and later reappear from it. (ii) The tradition in later writers. It is true, says Dörpfeld, that we have no express assertion that there was no stage—it never occurred to the older writers to say so, for they knew of no such thing. The later writers imply that there was none. Timæus,[164] commenting on ὀκρίβας, says: “for there was not yet a _thymele_”. _Thymele_ there means “stage”. Several late writers tell us that the Roman _logeion_ (“speaking-place” or “stage”) was once called “orchestra”: this supports the view that the stage is part of the old orchestra, higher than the other portion (see below). The scholiast on _Prometheus Vinctus_, 128, remarks: “They (the chorus) say this as they hover in the air on the machine; for it would be absurd for them to converse from below [_i.e._ from the orchestra] to one aloft”. Now, the pro-stage theory makes all choruses do this. The scholiast on Aristophanes’ _Wasps_, 1342, writes: “The old man stands on a certain height (ἐπί τινος μετεώρου) as he summons the girl”. The word “certain” (τινός) implies that he knew nothing of a regular stage. Finally, if there was a definite and regular difference of position between actors and chorus, is it not astonishing (_a_) that there is in Greek literature no certain allusion to the fact, (_b_) that the older literature contains no word for the stage, the place where the acting was performed being referred to merely by reference to the _booth_ (ἐπὶ σκηνῆς and ἀπὸ σκηνῆς)?
