Atlantis is no mystery, it was an ice age empire which Plato said extended to the east from the Pillars of Hercules (Gibraltar) to Libya and the Tyrrhenian sea (Italy), to the west outside Gibraltar as well, how far he did not say, but clearly greater Atlantis was a coastal empire of navigators who according to Plato used bronze age technology and sailed all over the world based from its capital the city built by Posidon (Canaan’s son Sidon) and his son Atlas, submerged perhaps thirty miles south of Cadiz, five miles north of the ice age shoreline of the ocean (according to Plato).
Almost everyone thinks Plato said that the demise of Atlantis (and much of Greece) was 9,000 years before the greek historian Solon’s time (circa 600 b. c.), but the word year is of the same etymological root as the word hour, segments of time, so those segments of time commonly thought a year, 9,000 of them, were actually just months (lunar cycles), comporting with the bronze age technology and global navigation presented by Plato about that empire of the western Mediterranean and eastern Atlantic.
Nesos is the greek word for island or peninsula which Plato used to describe Atlantis, in the case of the city, an island of concentric ship canals, while greater Atlantis of a peninsula, the Iberian (named for the jewish patriarch Heber), so obviously it was not some huge island sunken out in the Atlantic, although there are impressive submerged ruins reported off the Azores which of course were part of the portion of Atlantis outside the Pillars of Hercules, in the middle of the Atlantic ocean.
The use of the prefix or word Atl manifests in the name of submerged Atlit Yam off the coast of Israel (the land of Canaan during the Ice Age), of course too the Atlantic ocean, and the names of the ancient mexican sea gods Atlahua and Atlanteotl who apparently were Atlas (a grandson of Canaan) deified. Atl meaning water is perhaps the original root of the word water, for the fame of Sidon and Atlas probably grew rapidly in the decades following the Tower of Babel which occurred about a hundred fifty years after Noah’s Flood, the warmer ocean in its aftermath which was the engine for the Ice Age.
Plato described the Atlantean Plain, 200 miles by 300 miles, at its north a mineral rich mountain range and at its south the city of Atlantis (five miles from the ice age seashore), this fitting perfectly with the Guadalquiver river valley of southwestern Spain and the Sierra Morena mountains nearby (the richest mining district in the ancient world), and submerged offshore are many sites of stone ruins for instance off Cadiz, Rota, Chipiona, and Zahara de los Atunes, so where is the National Geographic film crew, are the dozens if not hundreds of sites of submerged ruins worldwide really not worthy of study?
Basque is the remnant language spoken by the Atlanteans, who were Canaanites (Sidon and Atlas), so the Basque language resembling the Berber of North Africa and Canaanite too (Punic or Phoenician) thereby mirrors the extent of greater Atlantis described by the greek Plato, with the Vasconic (Basque-like) languages of the western Mediterranean and eastern Atlantic bearing further witness, Basque the substratum of otherwise indo european (japhetic) languages which came to dominate when the Ice Age ended, when the region became known as Tarshish, named for those of the the river valley of Tarshish (a grandson of Japheth) of coastal southern Turkey who sailed to Spain when the Ice Age ended.
