I wonder if the craftsmen also knew that the windows were a little wedge shaped from manufacture and put the thick bit at the bottom. That's what I'd do at least, makes sense structurally. Then later, random people made guesses as to the 'flow' of glass because all the windows are thick on the bottom... If anyone can confirm this theory, you and I will feel eternally smug. Best of luck!
