You can argue semantics on this, but "wasn’t known to the Greeks of the first century BCE" is basically accurate, or certainly "accurate enough" for this context. All of the heliocentric writers were basically little more than "this idea some guy had", and geocentric views as described by e.g. Aristotle were dominant.
- globnomulous 2y agoIf that's true, then by the same reasoning you're also saying that heliocentrism wasn't known to the Europe of (insert any time before the mid 1600s), because it was little more than an idea some guy had, not dominant or accepted. But nobody would characterize the history of the science that way, because it simply isn't true. "Wasn't known to the Greeks" is inaccurate, particularly in its historical context, since science and philosophy were often "little more than 'this idea some guy had.'"
- noncoml 2y agoDoes geocentric go hand in hand with flat earth? Because it was pretty common scientific knowledge that earth was round back then. A knowledge that got lost during the dark ages. For example: In the third century BCE , Eratosthenes, a Greek librarian in Alexandria , Egypt , determined the earth's circumference to be 40,250 to 45,900 kilometers (25,000 to 28,500 miles) by comparing the Sun's relative position at two different locations on the earth's surface.

- zardo 2y agoI meant specifically that the Earth is roughly ball shaped.
- ithkuil 2y agoI suggest you read about it again. It was about geo-centric vs helio-centric models. It was not about flat vs globe. The geo-centric model assumed the earth was spherical but it didn't rotate or otherwise move.
- atmosx 2y agoTrue, I didn't follow the thread closely, my bad.
