Thomas Aquinas (medieval Catholic philosopher) knew the Earth was round [1]. If your first point was to suggest that the roundness of the Earth disappeared with ancient Greece -- that didn't happen. Nor did the Renaissance rediscover that point, specifically. > The consensus at the time, among the learned (i.e. Catholic Church and a few scientists with royal patronage here and there) was that the Earth was probably round, and probably small enough that you could maybe sail all the way to China and India from the edge of Europe - but they had no idea that there was land in between. The first point is not probabilistic. The second, sure. It's only some Americans at this point who doubt the Earth is round.
