"According to legend, Atlantis is a lost island in the Atlantic Ocean that Plato claimed was swallowed by an earthquake."
A mythical country said to have sunk into the Atlantic Ocean.
"Legends describe Atlantis as a magnificent civilization that once existed before sinking beneath the waves of the Atlantic Ocean."
The name Atlantis comes from the Ancient Greek word for Atlas, a figure known in mythology as holding up the sky. The original meaning suggests that this giant was named because he bore an immense weight, though some scholars believe the root may have come from before the Greeks spoke their language.
