Note 318 — Chapter V · THE INFLUENCE OF PHYSICAL CONDITIONS[308]
Reading edition
The Ajax is one of the earliest among Sophocles’ extant plays, but its exact date is not known. I have assumed that it preceded the introduction of a proscenium about 430 B.C. (see p. 235, above). If it was written after that innovation, the statement in the text would have to be altered accordingly, but the general method of procedure remains the same in either case.
