Best Answer

Pythagoras first proposed that the Earth must be a sphere in 570 BC. In the third and fourth centuries B.C., Plato and Aristotle agreed based on the curved horizon at sea and the shadow on the moon during an eclipse. In the third century B.C., Eratosthenes calculated the circumference by measuring shadows at the summer solstice at different locations. His estimate was within 10% of today's accepted value.
