Which culture first proposed the concept of a lost city called Atlantis?

The concept of a lost city called Atlantis originates from ancient Greek culture. This idea was first introduced by the philosopher Plato in his dialogues "Timaeus" and "Critias," written around 360 BC. Plato described Atlantis as a powerful and advanced civilization that existed approximately 9,000 years before his time, located beyond the "Pillars of Hercules" (what is now known as the Strait of Gibraltar).

Plato's accounts of Atlantis have fueled numerous theories and myths about lost civilizations throughout history, contributing significantly to Western literature and philosophy. His vivid descriptions and philosophical implications have made Atlantis not just a geographical concept but also a symbol of idealism and caution regarding human civilization's potential downfall.

Other cultures mentioned in the options do not have a historical foundation for the concept of Atlantis in the same way that the Greeks do. While there may be legends from other cultures that feature lost cities or civilizations, they are distinct from Plato's specific narrative of Atlantis. Thus, the Greek attribution is essential for understanding the origin of the idea.
