In Eastern Europe, people nailed shadows to walls to keep them from fleeing bodies and joining with spirits

A closer look

To most of us, a shadow is only a darker twin that obediently follows wherever light commands. But centuries ago, in the kingdoms of Eastern Europe, shadows were thought wilder—spirits waiting for a chance to slip away. People feared the unsettling idea that a wandering shadow might mingle with restless ghosts. And so, in dim-lit rooms, they drove nails into walls, pinning their shadows down, as if fastening their very essence in place. It’s a striking image: a world where even something as ordinary as your own outline might betray you, unless held captive by hammer and nail.
