HISTORY

The Claim

During the Middle Ages, scholars thought the Earth was round.

The Short Version

Historical evidence shows medieval scholars generally regarded Earth as spherical. Primary texts and standard scholastic teaching support that conclusion, especially in Latin Christian and university contexts. The common idea that medieval thinkers believed in a flat Earth is largely a later myth and often confuses popular belief with learned scholarship.

Caveats

  • This applies to scholars and educated traditions, not necessarily to all medieval people.
  • The evidence is strongest for Latin European and university-centered scholarship, not every region of the medieval world.
  • A few obscure writers disagreed, but they were exceptions rather than the scholarly norm.
