GGG Ping.

I'm choosing the melting glaciers/end of Ice Age as the cause of sinking.

[Just another Joe]

I postulate that a GREAT BIG FAT elephant sat on that portion of the land and it sank because it couldn't support the weight.

Either that or an earthquake maybe sank the portion of land beneath the waves.

I thought the rise in the level of the Black Sea that broke the dam and formed the Bosporus caused the water level rise in the Med.

Polar shift did all that.

My guess is first a mega tsunami, then the rising sea as the ice age ends covers the site.

"Atlantis" by Donovan

The continent of Atlantis was an island
which lay before the great flood
in the area we now call the Atlantic Ocean.
So great an area of land, that from her western shores
those beautiful sailors journeyed
to the South and the North Americas with ease,
in their ships with painted sails.

To the East Africa was a neighbour, across a short strait of sea miles.
The great Egyptian age is but a remnant of The Atlantian culture.
The antediluvian kings colonised the world
All the Gods who play in the mythological dramas
In all legends from all lands were from fair Atlantis.
Knowing her fate, Atlantis sent out ships to all corners of the Earth.
On board were the Twelve:
The poet, the physician, the farmer, the scientist,
The magician and the other so-called Gods of our legends.
Though Gods they were -
And as the elders of our time choose to remain blind
Let us rejoice and let us sing and dance and ring in the new
Hail Atlantis!
Way down below the ocean where I wanna be she may be,
Way down below the ocean where I wanna be she may be,
Way down below the ocean where I wanna be she may be.
Way down below the ocean where I wanna be she may be,
Way down below the ocean where I wanna be she may be.
