I think we could learn a lot from the Egyptians in
this matter. Too bad
they didn't leave behind a reference guide.
I've heard two plausible theories - a) they wrapped rounded blocks on all
four sides of the massive stone blocks and rolled them around and b) they
actually cast the blocks in place - they aren't stone, they are more akin
to concrete made from something other than limestone. Now Stonehenge
(an ancient calculating device, so perhaps more On Topic) may have been
built by building cofferdams around pairs of the vertical stones (plinths?)
and floating the horizontal stones up into place on rafts. _That_
technique
might work for raising RA-81s...
