Fascinating and thought provoking! I'm going to read them again when I have fewer distractions. I'm still on the fence about what I think. I was talking to my husband about all of this (he's a mason) and he said the Egyptian's were the master's and today's mason's are lazy and have it too easy, and this is coming from a man who can lay about 50 linear feet a day, and that's not including laborer's etc. He did say, that the lifting is the issue, laying it is not. Having said that, here is a link I found but have not explored fully as I'm chatting about the theories with hubby, but, will later.
