One man, One 26,000lb stone, one 2 pound hammer.

Got something interesting from Archeological Magazine. Archeologists studying medieval Chinese texts have published an alternate method of moving large stone blocks, in this case the 100 ton plus blocks used to build the Forbidden City. Ice roads, covered with a sheet of water. 1,500 men to move such a block over dry ground. 50 men to move a block over a water covered, ice road. Now, did Winter temperatures a Baalbek reach freezing or lower?
