Plato's Atlantis

Plato's Atlantis is a legendary island described in his dialogues, primarily "Timaeus" and "Critias." He portrays it as a powerful, advanced civilization that existed around 9,000 years before his time, said to have drifted beyond the Pillars of Hercules (the Strait of Gibraltar). According to Plato, Atlantis was a prosperous society with impressive technology and architecture, but its people became corrupt and arrogant. As a result, the gods punished Atlantis by sinking it beneath the ocean in a single day and night. The story serves as a moral allegory about hubris and the decline of moral virtue.
