The cosmology of the Syntaxis includes five main points, each of which is the subject of a chapter in Book I. What follows is a close paraphrase of Ptolemy's own words from Toomer's translation.[4]

>The celestial realm is spherical, and moves as a sphere.
>The Earth is a sphere.
>The Earth is at the center of the cosmos.
>The Earth, in relation to the distance of the fixed stars, has no appreciable size and must be treated as a mathematical point.[5]
>The Earth does not move.

So did Ptolemy not realize that the existence of mountains disproved his cosmology?
>mfw Greek "astronomers" didn't know what a sphere is
