1. IN the theatres of the Greeks, these same rules of construction are not to be followed in all respects. First, in the circle at the bottom where the Roman has four triangles, the Greek has three squares with their angles touching the line of circumference. The square whose side is nearest to the “scaena,” and cuts off a segment of the circle, determines by this line the limits of the “proscaenium” (A, B). Parallel to this line and tangent to the outer circumference of the segment, a line is drawn which fixes the front of the “scaena” (C-D). Through the centre of the orchestra and parallel to the direction of the “proscaenium,” a lineis laid off, and centres are marked where itcuts the circumference to the right and left (E, F) at the ends of the half-circle. Then, with the compasses fixed at the right, an arc is described from the horizontal distance at the left to the left hand side of the “proscaenium” (F, G); again with the centre at the left end, an arc is described from the horizontal distance at the right to the right hand side of the “proscaenium” (E, H).
