hi again #3i. Please forgive me if I have jumped too hastily to a conclusion, The formula I used was 'biggest stone ever moved' compared to one over 'ten times' bigger, that 'wasn't' moved = 'conclusive proof of impossibility'
However... I did a bit of research into the 'thunderstone', -as already mentioned, it was only moved 6km inland to the shore (where it was loaded on a mamoth barge), and presumably on a flat to gentle gradient, where as the giant stele at yangshan quarry is just over 15km as the crow flies from the ming xiaoling mauseleum (perhaps it will be over 20km by the time you've established a sensible route that keeps as even a gradient as possible). Also thats presuming that that would have been the intended site for erection, I don't know,do you know #3i?
So far then, so good, a question of scale possibly. Ten times heavier, three or four times further away, but all downhill which is a
big help ( BTW, I'm less than 60 kg, and I can pull over one and a half tonnes loaded on a pallet truck, but only on level ground, even the slightest gradient makes the task exponentially more difficult. The pallet truck has good bearings of course, and its ergonomiclly ideal for me to pull). What I discovered about the Thunderstone was that it also was pulled on bearings (a form of linear bearing, utilizing 6" bronze balls, in between a sledge track, and the track on the ground). Also, the man power was surprisingly minimal: 400 men in total, but with as few as 32 applying the 'moving' force by a mechanism described simply as capstans (something that needed to be rotated, like a car jack etc.). and they achieved 150m a day some days.
So, use 4000 men, extra bearings extra track scaled up sledge etc, allow a few years, and "perhaps" the stele could have been moved. I would say there would be a number of factors that would have needed resolving (terrain would be one of the primary ones), as in when you scale up a project other obstacles and unknowns can present themselves, also the engineering would have been quite critical I believe. i.e. I dont think rolling on logs etc would have been quite so effective.
I guess the incentive of keeping your head on your shoulders would help galvanize the work force somewhat!
So its a 'maybe' then, but ultimately we'll never know.
