Yes, I’ve seen those micro‑patterns before I finish a whole section of tracery. The artisans would carve a basic motif—say a fleur‑de‑lis or a vine—into a master template, then use that as a repeatable jig. It shows their obsession with precision, because any deviation in the stone would ruin the whole symmetry. It also hints at their desire to make the divine order visible: the same shape, the same rhythm, forever. And frankly, the only shortcut would be to let a machine do it, but they preferred the clack of hand‑chisels. So those tiny repetitions tell us they were meticulous, patient, and stubbornly opposed to the conveniences of later age.
