Acropolis is the name given to the central highest position in ancient Greek cities, occupied by the principal religious and civic buildings. The Athenian acropolis was crowned by the magnificent Parthenon, constructed between 447-432 BC. An interesting claim is that the Parthenon was once ‘a riot of colour’(d). Another remarkable feature of the building is that its breadth has been carefully measured at 101.34 feet, which is exactly a second of latitude at the equator(b). The acropolis of Athens is the best known and often erroneously referred to as ‘The’ Acropolis. It is worth noting that the general description of an acropolis is mirrored in Plato’s description of the central buildings of Atlantis that were also located on elevated ground. Writers such as Jürgen Spanuth, Rainer W. Kühne(a) as well as Papamarinopoulos(c) have concluded that the acropolis of Athens provides convincing evidence that the war between Atlantis and Athens took place around 1200 BC. Papamarinopoulos comments further that the “Athens of Critias, is proved a reality of the 12th century B.C., described only by Plato and not by historians, such as Herodotus, Thucydides and others. Analysts of the past have mixed Plato’s fabricated Athens presented in his dialogue Republic with the non-fabricated Athens of his dialogue Critias. This serious error has deflected researchers from their target to interpret Plato’s text efficiently.” (e)
Plato referred to dwellings for warriors (Crit. 112b) situated to the north of the Acropolis that were built in the 15th century BC and were not located again until the earlier part of our 20th century. He also refers to a spring (Critias 112d) that was destroyed during an earthquake. Kühne notes that this spring only existed for about 25 years but was found by the Swedish archaeologist, Oscar Broneer (1894-1992), who excavated there from 1959 to 1967. The destruction of the spring and barracks, by an earthquake, was confirmed as having occurring at the end of the 12th century BC. Plato describes how these catastrophes, of inundation and earthquake, that caused the destruction on the Acropolis, were only survived by those living inland, who were uneducated illiterate people, resulting in the knowledge of writing being lost.
J. Chadwick & Michael Ventris have shown that Linear B was written in an early Greek language and that in Greece it remained in use until around 1200 BC. Subsequently, the Greeks were without a script until the 8th century BC. This date of 1200 BC would appear to match the end of the war between Athens and Atlantis except for Plato’s reference to the earthquake being accompanied by a flood that was the third before the flood of Deucalion, usually dated to at least some centuries before 1200 BC, which implies an earlier date for the Atlantean war.
Collina-Girard in common with many others seems convinced that Atlantis was destroyed around 9500 BC but that Plato’s description of Atlantis is fictional. Collina-Girard’s theory of an Atlantis in the Gibraltar Strait inundated at the end of the Ice Age many thousands of years before the Acropolis existed, forced him to denounce Plato’s Bronze Age descriptions as fiction otherwise he could not justify the exploration of Spartel Island.
