Forty: “A Treatise on Terrene Traverse”

Mehrdad Afsari

Where these two lines begin is a point and there is no distance between them, but between the ends of these two lines the distance is one cubit. If you extend the two lines you have drawn to the earth out to the sphere, the distance between them will be two cubits where the sun is. We 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 light.*
