Regarding this, what did the ancient Greek astronomers believe was the Earth's shape?
Pythagoras is credited as the first Greek to think the earth spherical, but this idea was probably founded on mystic reasons rather than scientific. The earth's shadow on the moon's surface suggested that the shape of our planet was spherical.
Beside above, who supported the geocentric model? The most highly developed geocentric model was that of Ptolemy of Alexandria (2nd century ce). It was generally accepted until the 16th century, after which it was superseded by heliocentric models such as that of Nicolaus Copernicus.
Beside above, what discoveries did Greek astronomers make?
Pythagoras is generally regarded as the earliest proponent of a spherical Earth, although apparently not its size. Eratosthenes' famous and yet simple method relied on measuring the different lengths of shadows cast by poles stuck vertically into the ground, at midday on the summer solstice, at different latitudes.
Why was Aristarchus's model not accepted?
Why was Aristarchus of Samos' model not accepted at the time he proposed it? It was not accepted because at the time it was believed that the earth was at the center of the universe.
