who said the earth was round ?

Pinpointing a single person who definitively “said the Earth was round” is a bit tricky. The concept emerged gradually through the observations of several ancient Greek philosophers. Here’s a breakdown:

• Early Ideas (5th century BC): Around this time, Greek philosophers like Pythagoras began proposing a spherical Earth.

• Strong Evidence (3rd century BC): Aristotle provided strong arguments for a spherical Earth based on his observations of lunar eclipses and the way stars appeared different from various locations.

• Measurement (3rd century BC): Eratosthenes is sometimes credited as the first person to calculate the Earth’s circumference with remarkable accuracy.

So, while there wasn’t a single “Eureka!” moment, the idea of a round Earth gained traction through the work of these Greek scholars.

19 oct. 2023It is said that Socrates, the legendary Greek philosopher, first popularized the idea that the Earth was round instead of flat. He observed a lunar eclipse and realized that the shadow on the moon due to the earth was curved, which prompted him to deduce that the earth must be round if it were to cast a curved shadow. Additionally, the shape of …

The earth from space. When the ancient Greek philosopher Pythagoras first suggested that the Earth was round in 500 BC, his claim was dismissed as unreasonable. Decades later, Greek philosopher Aristotle proved Pythagoras correct when he concluded that the Earth was spherical by observing celestial bodies from different locations across the planet.

June, ca. 240 B.C. Eratosthenes Measures the Earth. By around 500 B.C., most ancient Greeks believed that Earth was round, not flat. But they had no idea how big the planet is until about 240 B.C., when Eratosthenes devised a clever method of estimating its circumference. It was around 500 B.C. that Pythagoras first proposed a spherical …
