Many ancient cultures subscribed to a flat-Earth. June 19, 1939: Dreaded ALS Gets a New Name - Lou Gehrig's Diseaseįeb. Flat Earth is an archaic and scientifically disproven conception of the Earths shape as a plane or disk. This knowledge spread with Greek influence. Columbus was one of the comparatively few people who at that time believed the earth to be round. One reason is that Eratosthenes' very own library of Alexandria had been destroyed, and there was no complete backup of its data. The belief was widespread in the Greek world when Eratosthenes calculated the circumference of Earth around 240 BC. But it was just not widely known among the masses in 15th-century Europe. The idea of the round Earth was more easily accepted by the navigators of the red seal ships, which were vessels authorized by the early Tokugawa government (1600-1635) to carry out trade in East and Southeast Asia.

Pretty darn good for a guy without modern measurement tools.Įratosthenes went further and computed the tilt of the Earth's axis to within a degree. The accepted figure for equatorial circumference today is 24,902 miles. Best Answer Copy Those who thought about it knew the Earth is round.

(We know he knew it was just a rough estimate, because he adjusted his initial number of 250,000 upward by 2,000 - or 0.8 percent - to make it divisible by 60 or 360 for easy computation.) And we don't know today the exact size of the measurement unit Eratosthenes was using when he came up with the final figure of 252,000 stades.
