Question

Throughout the Dark Ages Christians believed in a geocentric universe and such was taught as official Church doctrine, as seen in Dante's works, yet this view had come from a Greek (a pagan) who lived a long time ago. Name the Greek.

Answer 1

I think you're asking for the ancient Greek who believed we have a heliocentric universe. Check this site in the ancient Greco-Roman World section.

Answer 2

It was not until the times of Copernicus that heliocentrism was mathematically proven, of course. Although it was an interesting suggestion from the Greeks.
