I am confused: It says mosques, but then it states that only one mosque “passed the test”. Then there is this: “Among the 3,700 tiles Lu and Steinhardt mapped, there are only 11 tiny flaws, tiles placed in the wrong orientation. Lu argues that these are accidents possibly introduced during centuries of repair. “Art historians always suspected there must be something more to these patterns,” says Tom Lentz, director of Harvard University Art Museums, but they were never examined with “this kind of scientific rigor.”
Is it several mosques show this “ability” or one mosque?
Are these 11 flaws in the one mosque that “passed the test”?
If they are, why should they be ignored?
