Why would engineers and artisans who were clearly accomplished masters of efficient three dimensional design and construction deliberately and intentionally choose to adopt a construction technique that is so difficult to design, plan, measure, mark out, cut, place and position that it today confounds modern engineers and masons.
What was their reason for adopting this method? If they were using anything approaching known cutting and construction techniques then they certainly weren't trying to make life easy for themselves.
What could have been the design criteria that forced this approach?
How they achieved it is academic and possibly will never be known.
WHY did they do it? Why did they build a wall and why did they use this method?
