The bog was threshold space—neither land nor water, neither living nor dead, the acidic waters preserving what should decay, the anaerobic depths creating chemistry that transformed organic matter in ways that seemed supernatural but operated through mechanisms that modern science would eventually explain. Germanic peoples understood bogs as dangerous, sacred, and useful simultaneously, recognizing that the same properties that made bogs treacherous also made them medicinally valuable, that the waters which could preserve human bodies for millennia might also preserve human health when properly applied. This was not mystical thinking but pragmatic observation—bog water behaved differently than river water, affected wounds differently than well water, provided relief for conditions that other waters could not address.
