Key Takeaways on the Lost City of Atlantis: 

  • Atlantis did not exist. The philosopher Plato likely invented the nation to demonstrate the dangers of imperialism. 

  • It’s a landmass large enough that, if it really existed somewhere underwater in the Atlantic, it would certainly appear on sonar maps of the ocean floor.

  • Ignatius Donnelly published Atlantis: The Antediluvian World, which laid out 13 hypotheses, centered on the idea that Atlantis had truly existed, and indeed represented a place, and is why the myth continues today.


Atlantis: the legendary island that sank beneath the waves in the distant past, taking down with it an advanced civilization. Is it possible that we will ever find it? Or, more importantly: Did it even exist?
