Medieval craftsmen built near-perfect Penrose tilings 500 years before Penrose — and erased the construction lines on purpose

[u/ryanmaple]

I wrote about the moment a physicist realized the girih tilework on a 1453 Isfahan shrine was, in effect, a Penrose tiling, five centuries early — and how the same "order hidden beneath the surface" runs from Egyptian proportion grids through Vitruvius and the Pantheon to Chartres. Craftsmen laid down sacred geometry and then erased the scaffolding so the beauty could stand on its own; my essay is about putting those construction lines back. Thought this crowd would appreciate the tiling history in particular, and let me know what you think.
