Don't know if anybody cares. Did some petty research in science history.
Around the middle of the first millenium BC astronomers had realized that earth is curved. Curved, not necessarily spherical.
The "astronomers", not the "Greeks"! And the main reason was the observation that the height of stars and of the sun altered with latitude, which otherwise could not be explained. Since Babylonia was still the center of astronomy then, not Greece, the curvedness of earth's surface was much likely a Babylonian ("Chaldaean") discovery. As late as 500 AD Cosmas Indicopleustes noted, that the Chaldaeans conceived earth as having the shape of a shield, that means a disc but with a bulge.
In the time of Plato and Aristotle this was the main model taught by natural philosophers like Anaxagoras and Democrit, while the progression to a spherical model was initially rather a philosophical, even mystical thing. The first who taught like that were the Pythagoreans, because they considered the sphere as the most perfect shape. For Plato earth was a sphere, but his conception was weird, because for him the material world was something like a valley in a huge sphere-shaped thing that constituted the real "ideal" world from which the world we conceive is just a shadow. It's understandable that more sober minds prefered to hold to the shield model. With the likes of Aristotle everything changed, he formed the spherical earth model into a scientific theory which explained phenomena at best. Later on all philosophical schools in Greece had earth as a sphere exept the Epicureans, the most materialistic school, who retained the shield model.
So FEs are right when they say, "Globularism" comes from philosophy, not from science. But they are only partial right, because the discovery of the curvedness of earth predates globularism and did not originate from speculation but from evidence.
