Atlantis
mythological large island in Plato's dialogues

Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, romanized: Atlantìs nêsos, lit. 'island of Atlas') is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. By describing Atlantis as a naval empire from the west that had conquered most of Europe and Libya, Plato purposely created a literary contrast with the Achaemenid Empire, the great land-based power that ruled the east (what the Greeks called Asia). In Plato's account, Atlantis loses divine favor after an ill-fated campaign against a fictionalized Athens, and subsequently submerges into the Atlantic Ocean. By portraying the victorious Athens in the image of his ideal state from the Republic, Plato intended the Atlantis story to bear witness to the superiority of his concept of a state.
Despite its minor importance in Plato's work, the Atlantis story has had a considerable impact on literature. The allegorical aspect of Atlantis was taken up in utopian works of several Renaissance writers, such as Francis Bacon's New Atlantis and Thomas More's Utopia. On the other hand, nineteenth-century amateur scholars misinterpreted Plato's narrative as historical tradition, most famously Ignatius L. Donnelly in his Atlantis: The Antediluvian World. Plato's vague indications of the time of the events (more than 9,000 years before his time) and the alleged location of Atlantis ("beyond the Pillars of Hercules") gave rise to much pseudoscientific speculation. As a consequence, Atlantis has become a byword for any and all supposed advanced prehistoric lost civilizations and continues to inspire contemporary fiction, from comic books to films.
While present-day philologists and classicists agree on the story's fictional nature, there is still debate on what served as its inspiration.

Why this record matters
“Atlantis” is worth following because a concise public description often conceals a longer documentary argument. Here, Atlantis, mythological and large provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q25373. The Library of Congress control number is sh85009219. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
