tl;dr but saving for later, thanks. I think all that Greco - Roman stuff was Etruscan, (et-RUS-can, Russian) or more precisely Tartarian, or even Atlantean. The worldwide culture that built all those great buildings and megaliths was still around much more recently than they want us to think. Tartaria still existed in the mid 1800's
you should put it in your head since you don't have one
