I've seen bits of it. It reveals that Stukeley suggested they may have moved the stones in the manner of a galley - so it's publication is brilliantly timed!
He did a sketch of it. Strange though, he has the oars above the stone, pulling it up by ropes, not underneath levering it. And the oars were pivoting not on a fulcrum log but on a naff contraption comprising three spindly sticks leant together like a wigwam.
The question arises, if he thought of the mechanical concept, why would he specify it in such an impractical way? Someone on here (who may/may not wish to admit to it when they next visit) had a fantastic thought. Who was one of Stukeley's big buddies, that he used to discuss "matters diverse" with for hours, and who knew a thing or two about levers and forces?.....
Did William get told verbally, then go off and sketch it wrongly and forget to give credit to his source? Has Stone Rowing got a very authoritative supporter?
