I came across a very interesting website a few days ago while looking for info on the Phaistos Disk and its loaded with all kinds of cool info you
should check this site out when you got plenty of time to read but i found this about a lost civilization in Plato's " Timaeus":
""O Solon, you [Greeks] are all young in your minds which hold no store of old belief based on long tradition, no knowledge hoary with age"
" The reason is this. There have been, and will be hereafter, many and diverse destructions of mankind, the greatest by fire and water, though other
lesser ones are due to countless other causes"
" Thus the story current also in your part of the world, that Phaethon, child of the Sun, once harnessed his father's chariot but could not guide it
on his father's course and so burnt up everything on the face of the earth and was himself consumed by the thunderbolt - this legend has the air of a
fable; but the truth behind it is a deviation of the bodies that revolve in heaven around the earth and a destruction, occurring at long intervals, of
things on the earth by a great conflagration...."
"Any great or noble achievement or otherwise exceptional event that has come to pass, either in your own parts or here or in any place of which we
have tidings, has been written down for ages past in records that are preserved in our temples;"
"whereas with you and with other peoples again and again, life [had only just] been enriched with letters and all the other necessities of
civilization when once more, after the usual period of years, the torrents from heaven [swept] down like a pestilence, leaving only the rude and
unlettered among you"
"And so you start again like children, knowing nothing of what existed in ancient times here or in your own country.... To begin with, your people
remembered only one deluge, though there were many earlier;"
"and moreover you do not know that the noblest and bravest race in the world once lived in your country. From a small remnant of their seed you and
all your fellow citizens are derived; but you know nothing of it because the survivors for many generations died leaving no word in writing""
