3The angles thus pointing to staircases will be seven in number, the remaining five will mark certain points on the scene. That in the middle, for instance, will mark the situation of the royal doors, those on the right and left, the doors of guests, and those at the extremities, the points at which the road turns off. The seats (gradus) on which the spectators sit are not to be less than twenty inches in height, nor more than twenty-two. Their width must not be more than two feet and a half, nor less than two feet.
3The angles at the bottom, which give the directions for the flights of steps, will be seven in number (C, E, F, G, H, I, D); the other five angles will determine the arrangement of the scene: thus, the angle in the middle ought to have the “royal door” (K) opposite to it; the angles to the right and left (L, M) will designate the position of the doors for guest chambers; and the two outermost angles (A, B) will point to the passages in the wings. The steps for the spectators’ places, where the seats are arranged, should be not less than a foot and a palm in height, nor more than a foot and six fingers; their depth should be fixed at not more than two and a half feet, nor less than two feet.
