The two facts already mentioned—first, the fact that Vitruvius tells us that every Greek theatre should possess a stage of a certain height, and secondly, the fact that all Greek theatres after about 300 B.C. are found to possess a stage corresponding to his description—these two facts appear sufficient in themselves to decide the whole question. But there is no lack of further evidence. Various ancient writers may be cited as witnesses. Pollux, in his description of the Greek theatre, says that ‘the stage is appropriated to the actors, the orchestra to the chorus’.[466] Later on he says that the actors, when they ‘enter by the orchestra, ascend the stage by means of steps’.[467] The scholiasts to the extant dramas often speak of the performance in a Greek theatre as being partly in the orchestra and partly on the stage. The commentator on the Frogs asserts that the scene with Charon and the ferry-boat must be ‘either upon the logeion, or in the orchestra’. Later on he says that Dionysus here appears ‘not on the logeion, but in the orchestra’. The scholiast on the Knights discusses the question why the sausage-seller should ‘ascend from the parodos on to the logeion’. There are other scholia to the same effect, which it would be tedious to quote.[468] In these passages from the scholiasts and from Pollux the point to notice is the following. They do not merely say that there was a stage in Greek theatres, but they describe the performance as one partly on the stage, and partly in the orchestra. Dörpfeld says they are all mistaken; that they lived after the Christian era, and were confusing the Greek theatre with the Roman. But this would not account for their mistake, if mistake there were. In Roman theatres all performances were confined to the stage; the orchestra was occupied by senators and other distinguished persons. How then can Pollux and the scholiasts have got this notion of a performance in which stage and orchestra were used at the same time? There was nothing in the Roman practice to suggest it. It can only have been derived from the Greek theatre. But apart from this, the suggestion that Pollux and the scholiasts were misled by their recollection of Roman customs is not a fortunate one. It implies that their writings were the result of personal observation. But no one can read a page of them without perceiving that they were merely compilations from Alexandrian sources. The scholiasts in many cases mention their authorities, and these authorities often go back as far as Aristophanes and Aristarchus, and even beyond. They do indeed confuse the evidence a good deal, when they try to reconcile different statements, or when they misapply statements of earlier authorities to particular passages, and explain the passages wrongly; but the statements themselves are due to Alexandrian tradition, not to their own observations. When they say that Greek dramas were performed partly on the stage and partly in the orchestra, it is
