Do the Timaeus and Critias contradict each another?

Blue hue I am going to repeat what I have already stated, and if you so choose to ignore the facts then your entire foundation upon which you have built your theory, will crumble!  And I do emphasize the word THEORY!   Without proof that all it is, you can keep repeating it until your BLUE in the face, but it’s still a theory.

“The word Nesos means Raised terrain!”  Which would mean that Atlantis was on a flat top hill or perhaps mountain.
Even if Nesos meant promontory like you state, that still doesn’t put Atlantis in the crater of a volcano.

I’m sorry Blue hue I need real proof.
