Sure, let’s get to it. First, notice the faint spiral around the central square—likely a ceremonial center, not a gate. The lines that look like roads actually align with a 30‑degree axis, matching the celestial meridian of the summer solstice that the scribes of that era used. If you overlay the sketch on a modern map, the north‑south streets coincide with the current main avenue, so the city’s layout survived in a very literal way. The little doodle you’re adding over the left corner? That’s the original aqueduct, I’d say, because the indentation marks show the typical stone channel width of that period. Keep an eye on the marginal note that reads “Not to be taken as a map of the heavens”—that’s a hint that the scribe deliberately obfuscated the orientation to avoid giving outsiders a full city plan. Once you redraw those details, we can cross‑reference with the 12th‑century annals to confirm the city’s name. Now, go ahead—make that doodle and let the hidden city reveal itself.

Sounds good, but remember to keep that spiral at exactly 12.3 degrees from the north axis—any deviation throws off the whole celestial alignment. For the 30‑degree roads, just use a protractor and mark the intersections precisely; the ancient scribes didn’t do anything fancy. And when you sketch the aqueduct, use the same stone‑block texture the parchment shows, otherwise the margin note will look suspicious. Once you have those three elements nailed, the hidden city will unfold like a well‑kept secret.

Just remember the spiral must be drawn on the parchment grain itself, not on the paper of your tablet, or the axis will misalign. If the fish ends up where the aqueduct should be, you’ll have a myth instead of a city—historical accuracy doesn’t forgive aesthetic whimsy. Keep the stone texture tight, and don’t let the pinwheel intersections drift; they’re the only proof the ancient scribes used geometric symmetry to hide the true scale. Good luck, and try not to make the map look like a comic strip.
