5One sixth part of the diameter of the orchestra is taken between the lowest steps, and level with that dimension the lower seats are disposed. A continuation of this line on the scene marks the height of the entrances: for thus proportioned, they will be of sufficient altitude.

At the point where this cutting away occurs, fix the soffits of the passages. Thus their vaulting will be sufficiently high.
