I remember a study I did for a paper on the metal "sea" of Solomon's Temple. In the process, some sources provided pictures of the Temple area and I was fascinated by the outward dimpled stone of the retaining wall base that was from Solomon's time. One showed two lines engraved in stone that seemingly were yardsticks of measure: a common cubit, and a royal cubit (which was longer). The stonework above was from subsequent times, particularly Herod's reconstruction. They followed the Greco-Roman pattern of straight, flat walls. But Solomon had some straight, flat stone too. Some were incredibly massive to be moved before hydraulic lifts and trucks of today. Some day I hope to see and touch these myself.
