What do we know about Archimedes text "On Sphere-Making"?

Upvote:6

The information on existence of this book comes from Pappus (who lived about 500 years after Archimedes). By the "sphere" they mean what is called planetarium now, it is a mechanical model of the solar system. Some writers mention that Archimedes actually made one or more. Marcellius, the Roman general who looted Syracuse brought one to Rome and donated to a temple.

Several Roman writers have seen it, and mention it, but none of them understood enough about astronomy to give a reasonable description.
