Flat Earth

• 1. Ancient Cosmological Models

  ›

  In the 6th century BC, Babylonian scribes carved a world map known as Imago Mundi onto clay. This artifact depicts a flat disk floating in an ocean called Bitter River. Surrounding this central landmass are distant regions labeled as foreign lands and mountains. The text describes the universe as a solid dome with stars embedded within it. Ancient Egyptian texts from the Pyramid Texts era describe Nun, the primeval ocean, encircling dry islands. These writings suggest that early Near Eastern cultures viewed the Earth as a disc surrounded by water. Homer's Iliad reinforces this view through the Shield of Achilles. The shield features Oceanus flowing around its circular edge. Poets like Hesiod and Stasinus of Cyprus also described a flat Earth model where the sun bathes at the edges of the surrounding sea. In ancient Greece, pre-Socratic philosophers debated these ideas. Thales believed the Earth floated on water like a log. Anaximander proposed a short cylinder shape with a flat top. Democritus and Leucippus supported the notion of a flat surface. By the 5th century BC, Anaxagoras agreed the Earth was flat. His pupil Archelaus suggested the middle depressed like a saucer to explain why the Sun rises and sets differently for everyone. Herodotus wrote about literal ends or edges of the Earth even while ridiculing the idea of water encircling the world. Norse cosmology placed Yggdrasil, the world tree, in the center of a flat disk. A massive snake called Jormungandr swam in the ocean surrounding the land. Chinese astronomers until the 17th century maintained that the heavens were round but the Earth was square. Zhang Heng used an egg analogy to describe the relative position of the flat Earth to the spherical heavens. Vedic texts from South Asia depicted the cosmos as a stack of flat disks. The Shatapatha Brahmana explicitly called the Earth circular. Later Puranas described a flat-bottomed disk surrounded by concentric oceans.

• 2. Medieval Sphericity Consensus

  ›

  By the early period of the Christian Church, the spherical view was widely held among theologians. Athenagoras wrote around 175 AD stating the Earth was spherical. Methodius argued against Chaldean and Egyptian theories by describing the universe as a globe. Arnobius described the world as neither right nor left with no upper or lower regions. Ambrose, Jerome, and Prudentius all supported the round Earth theory. Exceptions existed like Lactantius who ridiculed antipodes between 304 and 313 AD. Diodorus of Tarsus founded the School of Antioch which revived flat-Earth views in the East Syriac world. Cosmas Indicopleustes published Christian Topography in 547 claiming the Earth was a rectangle 400 days journey long. He dismissed spherical theory as pagan. However, most scholastic authors accepted sphericity during the High and Late Middle Ages. John of Sacrobosco taught this concept in standard university textbooks. Thomas Aquinas used the sphere as an example provable by two sciences. Bishop Isidore of Seville presented diverse views in his Etymologies encyclopedia from 560 to 636. His T and O map showed a disc but he also affirmed the sphere of the sky had Earth at its center. St Vergilius of Salzburg discussed geographical ideas that Pope Zachary found objectionable in 748. The imperial orb given to Henry II represented the earth with its rotundity. By the ninth century, Eratosthenes method for calculating sphericality appeared in Carolingian commentaries. Hermann of Reichenau included new methods using an astrolabe by 1013. Portuguese navigation down Africa in the latter half of the 1400s provided observational evidence. Ferdinand Magellan completed global circumnavigation in 1521 proving east-west curvature.

• 3. Islamic And Christian Debates

  ›

  Muslim scholars initially viewed the Earth as flat before Greek cosmology entered the Islamic world. Quranic verses describe the Earth as spread out which some interpret as flat. Fakhr al-Din al-Razi wrote Tafsir al-Kabir commentary in the 12th century arguing local regions are roughly flat while the whole is not. Ibn Hazm supported a ball-shaped Earth view. Beginning in the 10th century, traditionalists adopted spherical notions influenced by Ptolemaic astronomy. In early Christianity, Lactantius and Theophilus of Antioch held anti-Hellenistic views associating round-Earth theory with paganism. Chrysostom explicitly espoused that the Earth floats miraculously on water beneath the firmament based on scripture. Jacob of Serugh promoted these ideas through popular hexaemeral homilies. Severian Bishop of Gabala argued the Sun travels through northern parts hidden by a wall rather than passing under the Earth. Basil of Caesarea claimed the matter was theologically irrelevant. Cosmas Indicopleustes described four oceans surrounding a rectangular Earth enclosed by massive walls supporting the firmament. This view gained proponents like Ephrem the Syrian but had little influence on Latin West. Most medieval Christian writers felt little urge to assume flatness despite fuzzy impressions of Pliny. Eastern Roman Empire preserved Greek learning while Western Europe struggled intellectually after Rome fell. By the turn of the eleventh century, Hermann of Reichenau replicated Eratosthenes measurement using an astrolabe. Portuguese explorers found solar position moved northward further south giving evidence for crossing equator. Antonio Pigafetta recorded loss of a day during Magellan voyage proving east-west curvature.

• 4. Myth Of Medieval Ignorance

  ›

  A historical myth asserting medieval Europeans universally believed in a flat Earth emerged in the 17th century. American writer Washington Irving maintained Christopher Columbus faced church opposition to gain sponsorship. John William Draper and Andrew Dickson White used this narrative as element in their science versus religion conflict thesis. These advocates promoted the idea that scholars before Columbus thought the world was flat. Subsequent studies show most Middle Ages scholars including those read by Columbus maintained spherical Earth belief. The myth gained currency in the 19th century through popular literature. Early medieval writers often had fuzzy impressions of Ptolemy and Aristotle relying more on Pliny. They felt little urge to assume flatness except for specific theological objections. Jill Tattersall notes many vernacular works described Earth round like a table rather than apple. Language ambiguity existed but actual form suggested circle not sphere. No cartographical globe appeared before Martin Behaim Erdapfel from 1492. Imperial orbs representing rotundity were used since Henry II died in 1024. After eighth century Globe became part of medieval Christian picture without much debate. Discussion of Eratosthenes method appeared in Carolingian commentaries from ninth century. Most scientific treatises of classical antiquity unavailable leaving only simplified summaries. Eastern Roman Empire preserved learning while Western Europe entered Middle Ages with difficulties. Scholastics later helped by Arabic translators hardly needed struggle against flat-Earth legacy from early middle ages.

• 5. Modern Pseudoscientific Revival

  ›

  Pseudoscientific belief in flat Earth originated with English writer Samuel Rowbotham publishing Zetetic Astronomy pamphlet in 1849. Lady Elizabeth Blount established Universal Zetetic Society in 1893 which published journals. Samuel Shenton set up International Flat Earth Research Society known as Flat Earth Society in Dover England in 1956. This organization served as direct descendant of Universal Zetetic Society. Orlando Ferguson drew a Flat Earth map in 1893 containing biblical passages and refutations of Globe Theory. Modern believers face overwhelming publicly accessible evidence of Earth sphericity yet embrace conspiracy theories to maintain beliefs. They distrust observations they have not made themselves often accusing others of being in league with conspiracies. Governments media outlets schools scientists surveyors airlines accept spherical world creating tension for adherents. Believers tend to disagree with or accuse each other of complicity within the movement. The Flat Earth Society logo represents this modern revival. Membership increased alongside unaffiliated individuals using social media platforms since 2010s. A 2018 study reported by Scientific American found only 82 percent of 18 to 24 year old Americans agreed statement I have always believed world is round. Less than 2 percent acceptance exists across all age groups regarding firm belief in flat Earth.

• 6. Digital Age Dissemination

  ›

  Social media algorithms amplified flat Earth beliefs during the 21st century. YouTube Facebook and Twitter enabled individuals famous or not to spread disinformation easily. Online communities allowed rapid growth of membership in modern societies. Algorithms prioritize engagement over accuracy leading to wider reach for erroneous ideas. Digital platforms facilitate connection between previously isolated believers worldwide. Information flows faster than corrections from scientific institutions can respond. Conspiracy theories gain traction when governments and experts reject them. Social environment shapes child perception sometimes leading to false concept about shape beyond horizon. Education helps gradually change belief into realist one of spherical Earth. National Center for Science Education created site supporting teachers countering misinformation. Children often understand world is round confirmed by interviewing what pictures they draw actually mean. Yet digital echo chambers reinforce alternative cosmologies despite empirical evidence. Modern technology allows global coordination among disparate groups sharing similar doubts. The internet era transformed a niche movement into widespread phenomenon through networked communication tools. Believers use these platforms to challenge mainstream narratives without traditional gatekeepers filtering content. This shift marks evolution from physical pamphlets to viral videos and encrypted messaging apps.
