This chapter shows that the Earth is at the center of the cosmos. It establishes that the Earth occupies the exact center of the cosmos, by which it is enclosed, by again starting out from the procedure based on the fifth undemonstrated [argument constructed] through multiple [disjuncts]. If the Earth were higher than the center, then the half of the heavens above the Earth would not be visible, nor would the six zodiacal signs, nor half of the equinoctial circle, but less than all these [would be visible]. It has been illustrated that the Earth is not in any of the four regions. Therefore, it is necessary that it occupies the exact center of the cosmos.

Keywords:   cosmos, Earth, heavens, zodiacal signs, equinoctial circle
