have been much later. In 494 Aeschylus was only thirty-one; he had been only about fourteen or fifteen when Phrynichus began to exhibit, and when, therefore, there was still only one actor. The first tragic victory of Aeschylus was not gained till 484 B.C., though he is said to have competed as early as 500 B.C. It is very probable, then, that in the "Capture of Miletus" there was only one actor. If so, we have to imagine a narrative of the capture, diversified by the choral expressions of anxiety or sorrow; such a play as the Persae of Aeschylus would be, if, in addition to the Chorus of Persian elders, the only person in it were the messenger who describes the battle of Salamis and the retreat of Xerxes.
(3) The third step in the development was taken when Aeschylus added the second actor, and so made it possible to have a properly dramatic action. The date of the change is uncertain; but it was not later than 472 B.C., and probably some years earlier than 484 B.C. This change evidently required that the audience should be placed in the manner known from later times. While there was only one actor, the spectators could still stand round in a complete circle, as of old; the actor could address himself to different points at different moments. But with two actors it became necessary that the acting should be turned, as a rule, towards some one quarter; and therefore that the spectators should be arranged in something like a semicircle. We do not know how early this was done; but at any rate the old legend
