Sweet, was thinking of doing a fictional atlantis, write a fictional history based on current myth and religions.
Heck I should still have a 3d max model of an atlantean women inspired by the looks of the disney movie somewhere to make leader image. But it's been ages since I've done 3D and animation, never really got to it yet.
My opinion on Atlantis.
It's one of the many variations in global flood myths.
Many religions have a concept of creation and destruction of mankind happening over and over, repeating history but always different, though some are limited to only 1 previous earth like the old testament.
I especially like the mayan, incan and olmec civilization which have an actual calendar which is practical (farming etc.) and includes the cyclical creation and destruction of a version of mankind. We are in the 5th cycle which ends, supposedly, around 2012 according to their calendar. Which, by the way, is more accurate then our modern one, let's hope their religion isn't lol.
To me atlantis was in the old world before the great flood that destroyed mankind. All in all reading different religious texts, studying the aztec/mayan calendar (the thing fascinates me, can't help it). The best place for me to put something called Atlantis (culture, country, city, other (pre flood) word for human or mankind.) is in the previous (4th) cycle in the calendar, The last cycle was destroyed by flood according to the calendar, so that fits, so do the many religions that have a myth about the old being flooded and destroyed and the new starting after.
Getting carried away, won't bore you with the details, My interest is the calendar, Atlantis just seems to fit flood mythology to me. Especially combined with certain ancient indian texts and the cyclical understanding of time in the calendar. (which is surprisingly better then ours, maybe not correct but since we discovered time is anything but linear and unidirectional or real for that matter (seriously!). A straight line, one way road, is the furthest from reality possible.)
About plato, he learned the story from others in egypt. He might have made it into a moral story for education but he didn't make it up/suck it out of his thumb.
