That’s a tempting idea, but most of those old routes are just the most efficient ways to go from A to B. The lines are more about geography than binary code. Still, if you scan a 16th‑century atlas with a high‑contrast filter, you can see faint cross‑hatches that look almost like a circuit diagram. Maybe the cartographer was encoding weather patterns or trade routes, not a program. I’d love to pull one up and try to trace a “data structure” through the margins—just watch the ink for ink smudges, the little doodles that might be intentional. If you spot a pattern, send me a photo. I’ll check if it’s a hidden algorithm or just the chaos of a hurried hand.
