Plato`s Atlantis

Well, whatever Plato's descriptions gave about "Atlantis" have to be viewed with a grain of salt. Even after Thucydides, Greeks felt there was nothing wrong with mythologizing history - especially when one was recording ancient oral accounts, since it was to be expected that they would contain mythology which should not simply be lost and the chronicler could not objectively sort fact from fiction without being a witness or at least a contemporary of the events in question. There was a very wide latitude in mixing the two, especially in such cases of historical hearsay. So, any specifics given have to be regarded as little better than suggestions or rumours, and it is only the core elements of the story - an advanced island civilization of great antiquity destroyed somehow - that really have any meaning. Its location and features as given by Plato are extremely dubious, but there could be an element of truth to its essential parts. Minoa is a very good candidate - simply because it is strange to think there wouldn't be some echo of its story passed down through the ages.

The story of Atlantis is not offered by Plato as any sort of historical account, or even recounting of oral legend, it is actually presented as some sort of allegory for ideas about his "ideal state" mostly in the Critias dialogue. Here, then, he has an even wider latitude in terms of the specifics and is very much free to invent as little or as much as he chooses, and the reader would be expected not to take it literally. Treating it literally would have a number of huge problems in any case; for instance, Athens was reckoned by Plato to have been a contemporary of his Atlantis, and a powerful challenger to its power, and eventually its conqueror. In Plato's version, Atlantis falls not to earthquake but to Athens. It is actually Athens that suffers some sort of calamity related to an earthquake.

• c. 2600 - Danubian tribes (Seine-Oise-Marne) invade Armorica. As reaction, the Aquitanian tribes are organized as Artenac culture. VNSP-Atlantis fortifications are built.
  
• c. 2400 - Indo-European tribes invade Scandinavia and other regions of Northern and Central Europe, displacing the Megalithic religion from those regions. Aquitanians conquer all France and Belgium up to the Rhin, that becomes a stable border with continental IEs for more than 1000 years)
• c. 2200 - The new merchant organization of the Beaker People (probably of IE origin) reaches the coasts of the Western peoples.
• c. 2100 - VNSP becomes for two centuries the world-wide center of this Bell-Beaker phenomenon. It's probably the apogee of Atlantis.
• c. 1900 - Bell-Beaker guild dissolves in several smaller groups in Iberia, while its center goes back to Bohemia
• c. 1800 - Friendly Los Millares civilization is destroyed by El Argar (of simmilar culture but with Bornze tech). The cities south of VNSP-Atlantis are invaded by an ill-known people (discussed above). The formerly megalithic tribes of the Plateau are reorganized as non-Megalithic in Cogotas I culture (with bronze)
  
• c. 1500 - El Argar, now under strong Greek influx (El Argar B), launches a major strategy to control the strategic tin routes bypassing rival VNSP-Atlantis: planifies a colonization of La Mancha, in order to have direct access to the routes to the Plateau, the NW and Atlantic Europe. As a reaction Megalithists of Occitanie absorb Corsica and Sardinia in the "Atlantean sphere".
• c. 1300 - Everything goes to Hell: possible tsunami, simultaneous with Celtic invasions in Occitanie and NE Iberia cause the abandonement of VNSP cities and the disintegration of the Argarian centralized state into city-states. Probably Greeks remained around, obtaining tin, until their own destruction one or two centuries later.
  

Maju

 [Crit119d]:" and thither they assembled every fifth year, and then alternately every sixth year--giving equal honor to both the even and the odd--and when thus assembled they took counsel about public affairs and inquired if any had in any way transgressed and gave judgement" (transl.Bury).

The topics of the assemblies were nearly the same as in the case of the Etruscans. Perhaps it was the old tradition of the Atlanteans which gave the pattern for the Etruscan meetings.

It will be indeed a serious task to find out the 10 different organized culture substrates from the megalithic time which could have been the 10 Atlantean kingdoms. Up to now you mentioned three: the VNSP, El Agar, England.  I think we can consider also the Guadalquivier delta/Bay of Cadiz region, where the catastrophe has abandoned most of the remnants.

But how is it with the region of Brittany/France? How with northern and central Germany where the very sophisticated cultures called "Roessen" (4900-4200 BC), "Michelsberg" (4200-3500 BC) and "Wartberg"(3500-2800 BC) existed? The "Bell Beaker People" are found in Germany between 2600 and 2000 BC, and an older Beaker Culture between 2900 and 2400 BC which already used copper tools beside the usual flint and stone tools. 

Herr leave ,out athens and it history all together and what story is there in 600 bc.?

I think the greeks borrow the story just as they did with Deucalion  making the story their own. 

Deucalion's parallels with Noah and with Utnapishtin.

Maju could be right of the ten tombs( they could be the frist kings)  their desendants for many generations ruled over the diver islands, the story says it took generations of many kings to build the capital city. The city that sank was near gades. Tartessos.
