How sure are we?
We don’t hide the contested.
Most atlases of “ancient mysteries” either print every legend as fact or leave out anything unproven. We do neither. Every place carries a seal that says how much the evidence supports what is claimed about it — from peer-reviewed consensus to claims the field has rejected.
The seal sits on every card, every map pin and every page. Disputed places stay in the atlas, labeled. That is the point.
