^{page 55 note 1} There is much uncertainty as regards Epigenes; but I do not follow the Professor's argument on p. 68, that non-Dionysiac tragedy existed before the introduction of Dionysiac worship, because Epigenes was the fifteenth tragic poet before Thespis, who must have begun to perform about 570 B.C., whereas Dionysiac worship (according to the Professor) was not introduced into Sicyon before 600 B.C. There is plenty of room for fifteen poets in thirty years, as the Attic inscriptional evidence shows, even if the dates given are correct.

^{page 57 note 1} Prof. Ridgeway, p. 57, states that Aristotle ignored Thespis. He does not mention him in in the Poetics; but Themistius' reference shows that Aristotle attached some importance to him.
