You’re writing as if CRT were a set of policies instead of an academic discipline—that’s why everyone is asking you to clarify what you think it is before they reply. It’s like trying to respond to someone criticizing “quantum theory” whose argument is based on the economic effects of nuclear power plants.

I checked, and it looks like I oversimplified: Anaxagoras estimated that the moon was the size of the Peloponnesus and the sun was somewhat larger—but how much larger depended on how much further away it was, which he had no means of guessing.

His estimate of the moon’s size was derived from observations of a solar eclipse, in which the path of totality was about the size of the Peloponnesus—but he probably missed a lot of places that experienced a partial eclipse and didn’t make note of it.

The Greeks thought the sun was the same size as the Peloponnese peninsula.
