This coincidence assures him he is on the right track, and with great enthusiasm and hope he "represents the earth's orbit by a sphere as the norm and measure of all"; round it he circumscribes a dodecahedron, and puts another sphere round that, which is approximately the orbit of Mars; round that, again, a tetrahedron, the corners of which mark the sphere of the orbit of Jupiter; round that sphere, again, he places a cube, which roughly gives the orbit of Saturn.

The earth is the sphere, the measure of all; round it describe a dodecahedron; the sphere including this will be Mars.

Iamblichus here refers to the dodecahedron inscribed in the sphere.
