Here Sophocles says that he has completed a stage of Aeschylus' work, meaning that he went through a phase of imitating Aeschylus' style but is finished with that. Sophocles' opinion of Aeschylus was mixed. He certainly respected him enough to imitate his work early on in his career, but he had reservations about Aeschylus' style, and thus did not keep his imitation up. Sophocles' first stage, in which he imitated Aeschylus, is marked by "Aeschylean pomp in the language". Sophocles' second stage was entirely his own. He introduced new ways of evoking feeling out of an audience, as in his "Ajax", when Ajax is mocked by Athene, then the stage is emptied so that he may commit suicide alone. Sophocles mentions a third stage, distinct from the other two, in his discussion of his development. The third stage pays more heed to diction. His characters spoke in a way that was more natural to them and more expressive of their individual character feelings.
