Note 364 — Chapter IV · THE WORKS OF SOPHOCLES
Reading edition
The arrangement of the parts is not certain. But the important fact seems clear that a fourth actor was here used not tentatively (as in other cases) but in a very remarkable degree. Jebb gives: protagonist, Œdipus; deuteragonist, Antigone; tritagonist, Ismene and Creon; fourth actor, “Stranger,” Theseus, Polynices, messenger. Croiset: protagonist, Œdipus; deuteragonist, Antigone; fourth actor, Theseus; all the other parts to the tritagonist.
