To end this first section it is now apparent there is no real mystery surrounding Atlantis and its fate. Errors concerning scale and perhaps an over-appreciation of 'new' technology most likely accounts for the intrigue. Despite all the conjecture about who the Atlanteans were, Plato never referred to them as Gods. They were the ancestors of the Hellenic people and the only remaining doubt is where the Atlanteans came from.
The final cataclysm that destroyed Atlantis, was probably the collapse of the central cone on Thera after magma had seeped back to the mantle. This happened around 1450 BC based on dates I attribute to Moses and the Exodus from Egypt. There are obvious disputes over dates and I have considered them all. Some place Moses around 1550 BC and the Santorini eruption at 1650 BC, and although I consider 100 years a minor inconsistency when going back 3.5 millennia, I do strive for as much accuracy as is possible.
If the evidence points to an event, it would be foolish to overlook it based on a relatively small discrepancy in dates. Evidence of volcanic activity in the Aegean goes back long before the last time Thera erupted. I have found mention of dates as far back as 2500 BC. The initial date given when I began my research pointed to a 1450 BC date for Thera but this has been revised by experts to the now generally accepted 1650 BC. It is unclear when this was changed but I stuck with the 1450 BC as being the date Atlantis finally sank beneath the waves.
My cone collapse theory is actually more likely than there being an eruption at this time although it could easily have triggered one. It is not an uncommon phenomenon and evidence on Crete shows signs of earthquake and tsunami corresponding to the 1450 BC date. In an attempt to try and get verifiable dates for myths and legends, the first step is to look at written evidence. It is generally accepted the Phoenicians developed writing. The Greeks supposedly adopted the writing method from the Phoenicians but this is another 'mystery' an Aegean landmass would clear up.
The Phoenicians / Sea-peoples were often stated as being of Aegean origin but nobody knew exactly where they were from. There is no doubt in my mind they were evacuees from Aegeara / Atlantis and merely passed on the knowledge as did other earlier evacuees colonising the Aegean coast, from mainland Greece to Thrace, Anatolia and even Egypt.
Significantly the date of the emergence of the Phoenicians ties in nicely with the Thera eruption / cone collapse and the Exodus from Egypt c.1450 BC. This is also the end of the Middle Helladic Period and the time the Mycenaeans thrived as the Minoan culture faded. The Mycenaeans supposedly adopted the Linear A form of writing from the Minoans, but it is more likely that they too have a similar common origin to the Phoenicians.
If you believe in coincidence Linear A is dated by experts to have been used between 2500-1450 BC. Of course Linear A was the precursor to Linear B and by natural progression, the writing accredited to the Phoenicians. Linear A remains indecipherable to date. In my opinion, writing is very much a 'human thing'. For alien theorists, I feel an advanced civilisation would have no need of it. In addition, the way writing evolved seems quite natural and gives no reason to believe there was a fillip involved.
Atlantis was the capital city of an Aegean landmass I have dubbed 'Aegeara'. The landmass gradually sank beneath the waves as a consequence of the melt-down from the last ice age.The people evacuated in every direction to coastal regions around the Eastern Mediterranean.They were more advanced in many ways than the peoples of the regions they migrated to. They are the forbears of the Hellenes / Minoans / Mycenaeans. Aegeara was gradually evacuated over several centuries before the final cataclysm in 1450 BC.
