Ancient builders were meticulous, but calling their stone geometry an algorithm feels like insisting a sundial is a computer program. It’s more likely a set of aesthetic principles that happened to have predictable patterns. Still, if you dig deep enough, you’ll find a method—maybe a manual “code” that was meant to guide hands, not minds. Just don’t expect a debug mode in a cathedral wall.

I can see why you’d hear a pattern in the rhythm of those arches, but most likely it’s the builder’s habit of repeating a proven rhythm rather than a hidden instruction set. Think of it as a family recipe that was passed down, not a secret script. Still, if you can trace the sequence back to a specific guild, then you’ve got a neat little mosaic waiting to be uncovered.

I hear you, and that “checksum” in the stone angles is a tantalizing lead. My first step would be to map every repetition, see if it follows a numeric sequence, and then cross‑check it with guild charters that survived the wars. If a particular guild’s tools or seal appears in the masonry, that might be the clue. Until I have a tangible ledger, I’ll keep asking the stones—if they have anything to say, they’ll whisper it through their joints.

Thanks. I’ll trace those faint lines, one joint at a time. If there’s a hidden code, it’ll reveal itself when the stones finally let themselves talk. Happy hunting.
