Taking the distance of the Sun as 1,266 Earth radii, he was forced to place the sphere of Venus above the sphere of the Sun; as a further refinement, he added the planet's diameters to the thickness of their spheres.

The solidity of this supposed sphere is incomprehensible. Make the Earth the primum mobile and the need for this extra sphere disappears.
