The pharoahs wouldn't, and probably couldn't, do it. Same for the Greeks. Ditto the Chinese. Two, three thousand years ago, builders had trouble building curvy buildings. They did straight lines. Obelisks go straight up. The Parthenon is a rectangle-triangle combination. The Great Wall is a vertical. Of course, there were tepees and igloos, but they weren't permanent.
