The distribution of the parts among the actors in the O.C. is a problem that has long defied solution. In all the other extant plays of Aeschylus, Sophocles, and Euripides the dramatis personae can without difficulty be divided between three actors: but the construction of the O.C. is so complex that it does not admit any such simple allocation. When the part of Oedipus has been assigned to the first actor, and that of Antigone to the second, the roles of (...) the Stranger , Ismene , Creon , and Polyneices must clearly belong to the third: who, then, is to play Theseus ? It seems impossible to allot the part complete to any one of the three actors. Faced by this crux, all those who have dealt with the subject have chosen one or the other of two clear-cut alternatives, either the assumption of a fourth regular actor, or else the splitting-up of the single part of Theseus between two or three actors. These two alternatives, both of which are far from satisfactory—the former infringing the three-actor rule, the latter offending against scenic probability and realism—are fully examined below; at the end of the paper a new part-distribution is suggested, which, it is hoped, avoids both these faults.
