How did ancient sculptors achieve this extraordinary level of left to right facial symmetry in the colossal granite head of Ramesses II? A digital symmetry overlay measuring the eyes, nose, mouth and jawline reveals just how closely the two sides correspond raising a fascinating question about the tools and techniques used to shape such precise geometry in extremely hard stone. Was this simply the result of master craftsmanship, careful use of grids and measuring tools, and abrasive grinding, or does the precision point to techniques we still don't fully understand?
