2. As a result of this plan with three centres, the Greeks have a roomier orchestra, and a “scaena” set further back, as well as a stage of less depth. They call this the logei=on, for the reason that there the tragic and comic actors perform on the stage, while other artists give their performances in the entire orchestra; hence, from this fact they are given in Greek the distinct names “Scenic” and “Thymelic.” The height of this “logeum” ought to be not less than ten feet nor more than twelve. Let the ascending flights of steps between the wedges of seats, as far up as the first curved cross-aisle, be laid out on lines directly opposite to the angles of the squares. Above the cross-aisle, let other flights be laid out in the middle between the first; and at the top, as often as there is a new cross-aisle, the number of flights of steps is always increased to the same extent.
