Did you see the alphabet i posted in one of the posts above? The greek does resemble it.
I got a reply from the professor, and she and her college say it definately is not greek. The college suggested it might simply be nonsense scribbling.
So either it was of a very obscure language that isn't known or it isn't any real language.
I have to ask: sunkenciv, as you read the site before it went down, does he give any reason as to why nobody ever notived something inscribed on the piramid? Seems rather strange, don't you think?
