Of the materials available to the ancient Egyptians for moving large stone blocks, wooden sleds equipped with flat greased metal runners which might ride on parallel wet greased wooden rails gives a low coefficient of friction? It may not be easy to use such materials to make an efficient working system?
Are there other combinations of "common" materials which might have had a lower coefficient of friction?
Thanks for any help!
