What it is

A translation of and commentary on Aristotle for the king of France, arguing at length that nothing observable rules out the earth turning daily on its axis — and then declining to believe it.

Why it lasted

The most searching pre-Copernican discussion of the earth's rotation, written in French so that a layman could follow it.

Where to read it

Public domain and free to read in full, though not held here. The archives below have it.

These open a search on each archive rather than a direct link, which is the honest way to point at an edition nobody here has checked line by line.
