Atlantis, a legendary island in the Atlantic Ocean, lying west of the Strait of Gibraltar. The principal sources for the legend are two of Plato’s dialogues, Timaeus and Critias.
In the former, Plato describes how Egyptian priests, in conversation with the Athenian lawgiver Solon, described Atlantis as an island larger than Asia Minor and Libya combined, and situated just beyond the Pillars of Hercules (the Strait of Gibraltar). About 9,000 years before the birth of Solon, the priests said, Atlantis was a rich island whose powerful princes conquered many of the lands of the Mediterranean until they were finally defeated by the Athenians and the latter’s allies. The Atlantians eventually became wicked and impious, and their island was swallowed up by the sea as a result of earthquakes. In the Critias, Plato supplied a history of the ideal commonwealth of the Atlantians.
Atlantis is probably a mere legend, but medieval European writers who received the tale from Arab geographers believed it to be true, and later writers tried to identify it with an actual country. After the Renaissance, for example, attempts were made to identify Atlantis with America, Scandinavia, and the Canary Islands. The story of Atlantis, if Plato did not invent it, may in fact reflect ancient Egyptian records of a volcanic eruption on the island of Thera about 1500 bce. This eruption, one of the most stupendous of historical times, was accompanied by a series of earthquakes and tsunamis that shattered civilization on Crete, thereby perhaps giving rise to the legend of Atlantis.
Greek mythology
Body of stories concerning the gods, heroes, and rituals of the ancient Greeks and Classical antiquity. That the myths contained a considerable element of fiction was recognized by the more critical Greeks, such as the philosopher Plato in the 5th–4th century bce. In general, however, in the popular piety of the Greeks, the myths were viewed as true accounts. Greek mythology has subsequently had extensive influence on the arts and literature of Western civilization, which fell heir to much of Greek culture. Although people of all countries, eras, and stages of civilization have developed myths that explain the existence and workings of natural phenomena, recount the deeds of gods or heroes, or seek to justify social or political institutions, the myths of the Greeks have remained unrivaled in the Western world as sources of imaginative and appealing ideas. Poets and artists from ancient times to the present have derived inspiration from Greek mythology and have discovered contemporary significance and relevance in Classical mythological themes.
