Source-derived summary

The myth of the flat Earth, or the flat-Earth error, is a modern historical misconception that European scholars and educated people during the Middle Ages believed the Earth to be flat.

According to Stephen Jay Gould, "there never was a period of 'flat Earth darkness' among scholars, regardless of how the public at large may have conceptualized our planet both then and now. Greek knowledge of sphericity never faded, and all major medieval scholars accepted the Earth's roundness as an established fact of cosmology." Historians of science David Lindberg and Ronald Numbers point out that "there was scarcely a Christian scholar of the Middle Ages who did not acknowledge [Earth's] sphericity and even know its approximate circumference".

Historian Jeffrey Burton Russell says the flat-Earth error flourished most between 1870 and 1920, and had to do with the ideological setting created by struggles over biological evolution. Russell claims "with extraordinary few exceptions no educated person in the history of Western Civilization from the third century B.C. onward believed that the Earth was flat", and ascribes popularization of the flat-Earth myth to histories by John William Draper, Andrew Dickson White, and Washington Irving.

The earliest clear documentation of the idea of a spherical Earth comes from the ancient Greeks (5th century BC). The belief was widespread in the Greek world when Eratosthenes calculated the circumference of Earth around 240 BC. This knowledge spread with Greek influence such that during the Early Middle Ages (c. 600 –1000 AD), most European and Middle Eastern scholars espoused Earth's sphericity. Belief in a flat Earth among educated Europeans was almost nonexistent from the Late Middle Ages (c. 1300 –1500 AD) onward, though fanciful depictions appear in art, such as the exterior panels of Hieronymus Bosch's famous triptych The Garden of Earthly Delights, in which a disc-shaped Earth is shown floating inside a transparent sphere.

History

In Inventing the Flat Earth: Columbus and Modern Historians, Jeffrey Russell describes the Flat Earth theory as a fable used to impugn pre-modern civilization and creationism.

James Hannam wrote:

The myth that people in the Middle Ages thought the Earth is flat appears to date from the 17th century as part of the campaign by Protestants against Catholic teaching.

The current lead gives the account dated anchors—1870, 1920, 1000, 1300—that can be checked directly. The selected authority fields contribute no independent date.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as misconception that Europeans in Middle Ages believed in flat Earth. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q3272686. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1870, 1920, 1000 and 1300.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
