Note 570 — Chapter IV · THE SCENERY
Reading edition
Reisch (Griech. Theater, pp. 194, 200) thinks the actors’ booth was originally in the side-entrance to the orchestra. He thinks the first stage-buildings were erected about 465, when scenery was introduced; and that these buildings were henceforth used for actors’ rooms. But it is much simpler to suppose that the actors’ booth stood fronting the spectators from the first, and that it was gradually converted into a stage-building.
