Neolithic and Bronze Age stones in that weight class ... from disparate cultures. ancient-wisdom.co.uk When I still had cable I was a fan of the quasi-reality shows on the Learning andor Discovery channels that reproduced ancient feats. One team worked with a stone the size and weight of a large moai of Rapa Nui (Easter Island). The largest of these weighed one-tenth of the big plonker at Puma Punku, and they were moved with ropes and rollers and erected using A-frame "cranes". Using such basic tech, it takes 1-2 men per ton of stone, placing it within the realm of the feasible that the 800-ton stone was lifted, rolled and hoisted (one corner at a time) into place. The assigned age (over ten thousand years! How assigned?) I find to be fantastic. Megalithic construction seems to have started worldwide about five thousand years ago. The oldest known structure with somewhat trustworthy dating is Newgrange in Ireland, about six millennia of age. knowth.com
