The Keeper

For eleven years, Marta believed the beam swept.

She had watched it from the shore as a child — the slow, confident rotation of light across the water. She had seen it from boats. She had built her understanding of how attention works on this model: you sweep it across the world and whatever you catch in the arc, that's what you find.

When she took the keeper's post at thirty-two, she climbed to the lamp room on the first night and stood very close to the lens. She had expected to feel the beam moving past her. She put out her hand.

The beam did not move. The beam was fixed, pouring out sideways in a single direction, consistent and still.

The lens moved.

She watched it for a long time. The great Fresnel lens rotating around the light source, the light itself going nowhere, the motion of the lens making the beam appear to sweep.

She had been wrong for eleven years about which thing moved.

What else had she reversed?

She thought about conversations where she'd assumed the other person was rotating and she was the still point. Attention moving, being moved, who was source and who was lens. She thought about grief, which she had always imagined as the bereaved person turning toward and away from a fixed loss. But maybe the loss was what rotated. Maybe you stayed still.

The light just shone.

She went back down the stairs. The beam continued its apparent sweep. From the ground it looked exactly as it always had.

Understanding a thing differently does not change what you see. She wasn't sure whether that was comforting.
