EURIPIDES comes difficult to speak with assurance of the formal nature of the play or to generalize from it to the formal definition of fifth-century satyr-drama. Indeed, even if we possessed the requisite information, the very distance which separates the tragedy of Euripides from that of Aeschylus and Sophocles would tend by analogy to preclude a generalization about satyr-plays. One ancient writer, it is true, speaks of satyr-drama as being "tragedy-at-play" or "joking tragedy." 2 But this is hardly helpful, since it may mean either that satyr-drama was mock tragedy, or tragedy buffa, or pure farce, or simply a sportive treatment of the subject matter of tragedy. All of these are possibilities applicable to the Cyclops, but we have no evidence which might allow us to decide among them. In point of origins the satyr-play, like both comedy and tragedy, was closely bound up with Dionysiac fertility ritual. Even in the fifth century satyr-drama in its frequent obscenity, its conventional use of Silenus as "nurse" and companion of Dionysus, and its chorus of satyrs with their phalloi preserves more vividly than tragedy the memory of its origins. What the original connection between tragedy and comedy and "satyr" may have been, we do not know, though Aristotle in a much disputed passage asserts that the satyr-play was one of the early stages of tragedy; 3 but the value of the testimony appears Cyclops should be assigned to a group of three tragedies of which the extant Hecuba was one. (The Hecuba is dated, on very good grounds, almost certainly to 425 B.C.) The assignment is strengthened not merely by topical considerations (cf. E. Delebecque, Euripide et la guerre du Peloponn&se) but by very close formal resemblances be- tween the two plays. Thus the blinding of Polyphemus parallels the blinding of Polymnestor, and Polyphemus' final appearance from the eave vividly recalls Polymnestor's emergence from the tent. In both plays again, the guiding idea is that of civilized brutality, and in both cases a barbaric vengeance is taken upon a barbarian (Polymnestor, Polyphemus) by a "civilized" person (Hecuba, Odysseus). The final prophecies again closely parallel each other, and the portrayal of Odysseus in the Hecuba is given a great deal of point if we have in mind the sequel in Cyclops. In the dovetailing of actions and the reversal of roles, the two plays are strikingly similar. 2. Demetrius of Phalerum De interp. 169; cf. Horace Ar$ poetica 231~3?' 3. Poetics i449a 9 ff. 244
