Abstract
Many investigations into how ancient humans quarried, moved, and placed very large stones have resulted in a high level of uncertainty regarding likely methods used. Some suggested methods include using flotation (boats) in rivers and canals, simply dragging on top of the ground, sliding on logs, moving on rolling logs, and even giant wheels fixed to the ends of massive, quarried stones. Each of these methods (which may have been used, as well as others proposed) have advantages and disadvantages. Instead of reviewing these methods, in this paper the authors investigate the potential of using a simple type 2 lever in an unconventional way to achieve lift and horizontal movement simultaneously. The focus is upon mechanical advantage as opposed to in-depth analysis of operational logistics. Estimates of potential productivity and required resources, are included for comparison to some proposed dragging methods. The authors conclude that ancient people could have used this method, which only requires expertise in carpentry (timbers) and rigging (with ropes) to implement the technique, reduce labor, and increase productivity compared to dragging methods.
