He did not do so. Earth was well-known to be a globe for at least two hundred years before Eratosthenes' time. What Eratosthenes did was to measure the earth's circumference for the first time. He did that at some time between 236 BC and 195 BC.
The sieve of Eratosthenes was discovered in 223 BC.
The idea that the Earth is not flat was first proposed by ancient Greek philosopher Pythagoras in the 6th century BC. Later, the concept was further developed by other ancient Greek scholars such as Aristotle and Eratosthenes.
He postulated the circumference of the earth.
Eratosthenes is known for several significant contributions, and three notable things named after him include the "Eratosthenes sieve," an ancient algorithm for finding prime numbers, the "Eratosthenes measure," which refers to his method of calculating the Earth's circumference, and the "Eratosthenes crater," a large impact crater on the Moon named in his honor. His work laid foundational principles in mathematics, geography, and astronomy.
Eratosthenes is a Greek Philosopher whom ideas were way out of his time. He discovered two important things about the earth, one in which is that the world is shape like a sphere in which we know today because of satellite imagery but in that time they did not have the the thought nor the technology.The next thing he discovered is the Earth's circumference which was only off by 185 miles. Another important fact is that Eratosthenes was in charge of the library in the city of Alexandria.
