It reads very interesting, thanks for that, I know some of the techniques that are still used regular, with rope and wedge, but like the log on top and on the bottom and the rope, I have never seen it like this before, it looks absolutely construction usable. I can't say what the ancients did or didn't have developed but they did do things 'big' and must have had quite a few techniques.
I think you have proven that there is alot of experimental research that is worth a closer look.
