Why Do We Whisper Around Very Old Things?

Stand in front of something genuinely old — a cathedral, a case of Bronze Age pins, a tree with four hundred rings in it — and listen to what happens to the room. Voices drop about half a step. Nobody puts up a sign. Children do it too, and they have not been briefed.

The tidiest explanation is that we whisper around sleeping things, and very old things read to us as asleep rather than as dead. A ruin is not doing nothing; it is doing something extremely slowly. Lowering your voice is exactly what you would do walking past a bedroom door at two in the afternoon, unsure whether anyone is behind it.

The competing explanation is acoustic. Big stone rooms have long echoes and we adjust to them without noticing. It is a good theory that falls apart in a field. People whisper in front of the oldest yew in a churchyard with nothing overhead but weather, where there is no reverberation to be polite about. Whatever the whisper is for, it is not the architecture.

Which leaves the least scientific answer, and probably the right one. The object is not listening. The whisper is not information being withheld from it. It is a small involuntary way of conceding that the thing was here before you arrived and will be here after you have gone, and that the correct volume for saying so is quite low.
