At Ba'albek, in Syria, one of the stones in the wall of the acropolis is just over 64 feet long - about the lenght of a cricket pitch - and 13 feet high and 10 feet thick, a finely cut block laid flush with the wall face not at ground level but 23 feet up. No machinery that we have to-day could lift that stone and lay it at that height in the wall; acient man could do it because he had no machines.
