Show Summary Details


This chapter illustrates that the shape of the Earth is spherical. It also demonstrates that both the whole cosmos, and its most significant parts, do have the Earth's shape. It then shows that the the Earth is neither flat, nor concave, nor square, nor pyramidal. It reports that it is absolutely necessary that the Earth be spherical. It is necessary that the air enclosing the Earth also be a sphere, since exhalations from the whole of the Earth rise and flow together and thus fashion the same shape for the air too. The cosmos is the most complete of all bodies, while the sphere is the most complete of all shapes.
