Where these two lines begin is a point with distance between them; but between the ends of these two lines the distance is one cubit. If the two lines that you have drawn to the earth would be extended to the sphere, the distance between them will be two cubits, which is where the sun is. We have established that the sun was four cubits in diameter. Therefore, two cubits of the sun’s body are outside of the lines, one cubit on each side. If at the distance of one cubit there were sunbeams headed down to the first point on the moon, the light would meet on both sides of where the earth is in shadow, which is night. What lies between these lines from the earth to the remaining points is in the light.1
