Athanasius Kircher's map of Atlantis, in the middle of the Atlantic Ocean. From Mundus Subterraneus 1669, published in Amsterdam. The map is oriented with south at the top.
Atlantis (Greek: Ἀτλαντὶς νῆσος, "Island of Atlas") is the name of a legendary island first mentioned in Plato's dialogues Timaeus and Critias.
In Plato's account, Atlantis, lying "beyond the pillars of Heracles", was a naval power that conquered many parts of western Europe and Africa, over 9,000 years before Plato's own time � approximately 9400 BC. After a failed attempt to invade Athens, Atlantis sank into the ocean "in a single day and night of misfortune".
As a story embedded in Plato's dialogues, Atlantis is generally seen as a myth created by Plato to illustrate his political theories. Although the function of the story of Atlantis seems clear to most scholars, they dispute whether and how much Plato's account was inspired by older traditions. Some scholars argue Plato drew upon memories of past events such as the Thera eruption or the Trojan War, while others insist that he took inspiration of contemporary events like the destruction of Helike in 373 BC or the failed Athenian invasion of Sicily in 415�413 BC.
The possible existence of a genuine Atlantis was actively discussed throughout the classical antiquity, but it was usually rejected and occasionally parodied. While basically unknown during the Middle Ages, the story of Atlantis was rediscovered by Humanists at the very beginning of modern times. Plato's description inspired the utopian works of several Renaissance writers, like Francis Bacon's "New Atlantis". To this day, Atlantis inspires today's literature, from science fiction to comic books and movies, its name having become a byword for any and all supposed prehistoric but advanced (and lost) civilizations.
Plato's Account
These works, written in the year 360 BC, contain the earliest known references to Atlantis. For unknown reasons, Plato never completed the dialogue Critias; however, the scholar Benjamin Jowett, among others, argues that Plato originally planned a third dialogue titled Hermocrates. John V. Luce assumes that Plato � after describing the origin of the world and mankind in Timaeus as well as the allegorical perfect society of ancient Athens and its successful defense against an antagonistic Atlantis in Critias � would have made the strategy of the Hellenic civilisation during their conflict with the barbarians a subject of discussion in the Hermocrates. Plato introduced Atlantis in Timaeus:
Many great and wonderful deeds are recorded of your state in our histories. But one of them exceeds all the rest in greatness and valour. For these histories tell of a mighty power which unprovoked made an expedition against the whole of Europe and Asia, and to which your city put an end. This power came forth out of the Atlantic Ocean, for in those days the Atlantic was navigable; and there was an island situated in front of the straits which are by you called the Pillars of Heracles; the island was larger than Libya and Asia put together, and was the way to other islands, and from these you might pass to the whole of the opposite continent which surrounded the true ocean; for this sea which is within the Straits of Heracles is only a harbour, having a narrow entrance, but that other is a real sea, and the surrounding land may be most truly called a boundless continent. Now in this island of Atlantis there was a great and wonderful empire... (from Timaeus)
The four persons appearing in those two dialogues are the politicians Critias and Hermocrates as well as the philosophers Socrates and Timaeus, although only Critias speaks of Atlantis. While most likely all of these people actually lived, these dialogues as recorded may have been the invention of Plato. In his written works, Plato makes extensive use of the Socratic dialogues in order to discuss contrary positions within the context of a supposition.
The Timaeus begins with an introduction, followed by an account of the creations and structure of the universe and ancient civilizations. In the introduction, Socrates muses about the perfect society, described in Plato's Republic, and wonders if he and his guests might recollect a story which exemplifies such a society. Critias mentions an allegedly historical tale that would make the perfect example, and follows by describing Atlantis as is recorded in the Critias. In his account, ancient Athens seems to represent the "perfect society" and Atlantis its opponent, representing the very antithesis of the "perfect" traits described in the Republic. Critias claims that his accounts of ancient Athens and Atlantis stem from a visit to Egypt by the Athenian lawgiver Solon in the 6th century BC. In Egypt, Solon met a priest of Sais, who translated the history of ancient Athens and Atlantis, recorded on papyri in Egyptian hieroglyphs, into Greek. According to Plutarch the priest was named Sonchis, but because of the temporal distance between Plutarch and the alleged event, this identification is unverified.
According to Critias, the Hellenic gods of old divided the land so that each god might own a lot; Poseidon was appropriately, and to his liking, bequeathed the island of Atlantis. The island was larger than Libya and Asia Minor combined, but it afterwards was sunk by an earthquake and became an impassable mud shoal, inhibiting travel to any part of the ocean. The Egyptians described Atlantis as an island approximately 700 kilometres (435 mi) across, comprising mostly mountains in the northern portions and along the shore, and encompassing a great plain of an oblong shape in the south "extending in one direction three thousand stadia [about 600 km; 375 mi], but across the center inland it was two thousand stadia [about 400 km; 250 mi]."
Fifty stadia inland from the coast was a "mountain not very high on any side." Here lived a native woman with whom Poseidon fell in love and who bore him five pairs of male twins. The eldest of these, Atlas, was made rightful king of the entire island and the ocean (called the Atlantic Ocean in honor of Atlas), and was given the mountain of his birth and the surrounding area as his fiefdom. Atlas's twin Gadeirus or Eumelus in Greek, was given the extremity of the island towards the Pillars of Heracles. The other four pairs of twins � Ampheres and Evaemon, Mneseus and Autochthon, Elasippus and Mestor, and Azaes and Diaprepes � were also given "rule over many men, and a large territory."
Poseidon carved the inland mountain where his love dwelt into a palace and enclosed it with three circular moats of increasing width, varying from one to three stadia and separated by rings of land proportional in size. The Atlanteans then built bridges northward from the mountain, making a route to the rest of the island. They dug a great canal to the sea, and alongside the bridges carved tunnels into the rings of rock so that ships could pass into the city around the mountain; they carved docks from the rock walls of the moats. Every passage to the city was guarded by gates and towers, and a wall surrounded each of the city's rings. The walls were constructed of red, white and black rock quarried from the moats, and were covered with brass, tin and orichalcum, respectively.
According to Critias, 9,000 years before his lifetime a war took place between those outside the Pillars of Hercules (generally thought to be the Strait of Gibraltar) and those who dwelt within them. On a side note, a new hypothesis states that this amount of time may have been "misinterpreted" by Solon. The Egyptians used a lunar calendar based on months, and the Greeks a solar one based on years. It is therefore possible that the measure of time interpreted as 9,000 years may actually have been 9,000 months. This would place the destruction of Atlantis within approximately 700 years beforehand, as there are 13 lunar months in a year. Returning to the story, the Atlanteans had conquered the parts of Libya within the columns of Heracles as far as Egypt and the European continent as far as Tyrrhenia, and subjected its people to slavery. The Athenians led an alliance of resistors against the Atlantean empire and as the alliance disintegrated, prevailed alone against the empire, liberating the occupied lands. "But later there occurred violent earthquakes and floods; and in a single day and night of misfortune all your warlike men in a body sank into the earth, and the island of Atlantis in like manner disappeared in the depths of the sea."
