Flat Earth

The flat earth is a scientifically false hypothesis that the surface of the Earth is not roughly a sphere, but rather flat (a plane). Belief in a flat Earth is found in writings predating around 500 BC. Early Mesopotamian maps showed the world as a flat disk floating in the ocean.

This was a common belief until the Classical Greeks began to discuss the Earth's shape about the 4th century BC. One of the "giveaways" is that ships' masts disappear last as they move away from shore.

Eratosthenes (276 BC–194 BC) calculated the circumference of the Earth quite well.^[1] From then on, few educated people ever believed in its being flat, though the idea of a flat earth was still common among the less educated.^[2] Aristotle knew the Earth was round, that is to say, roughly spherical. (330 BC).

The large-scale shape of the Earth only matters when considering large distances, as it is hard to see the Earth's curve from the ground. Therefore in the Ancient world only sailors, astronomers, philosophers, and theologians would have cared about the Earth's large-scale shape.

The following authors argued for a spherical or ball-shaped earth: King Alfred of the Anglo-Saxons, Hildegard von Bingen, Thomas Aquinas, Snorri Sturluson, Marco Polo, Dante Alighieri, Christopher Columbus

Portuguese people explored Africa and Asia, Columbus sailed to the Americas (1492) and Ferdinand Magellan circumnavigated (sailed all round) the earth (1519-21). This proved finally, and in a practical way, that the Earth is a globe.

During the 19th century, the Romantic ideas about a European "Dark Age" made the Flat Earth model look more important than it ever had been in history.

In 1849, the Flat Earth movement was revived by Samuel Rowbotham, who wrote the book Zetetic Astronomy, which says that the results of his Bedford level experiment proved that the earth was flat.^[3]

The widely circulated woodcut is of a man poking his head through the firmament of a flat Earth to see the machines working the spheres. It was made in 16th century style but cannot be traced to an earlier time than Camille Flammarion's L'Atmosphère: Météorologie Populaire (Paris, 1888, p. 163). The woodcut illustrates the statement in the text that a missionary in the middle Ages claimed that "he reached the horizon where the Earth and the heavens met". That story may be traced back to Voltaire, but not to any known source in the Middle ages. The original woodcut had a decorative border that places it in the 19th century; in later publications, some claimed that the woodcut dated from the 16th century and the border was removed. According to an unproved story Flammarion ordered the woodcut himself; certainly no source of the image earlier than Flammarion's book is known.

An early mention in literature was Ludvig Holberg's comedy Erasmus Montanus (1723). A great many people disagree with Erasmus Montanus when he claims the Earth is round, since all the peasants believe it is flat. He is not allowed to marry his fiancée until he cries "The earth is flat as a pancake". In Rudyard Kipling's The Village that Voted the Earth was Flat, the main characters spread the rumor that a Parish Council meeting had voted in favor of a flat Earth.
