The Museum Conservators Who Repaint Nothing
Modern conservation is governed by a rule that sounds absurd until you understand it: every repair must be reversible.
A visitor watching a conservator fill a loss in a four-hundred-year-old panel would be forgiven for thinking they are watching a painter. They are watching the opposite of one.
The reversibility principle
The retouching medium is chosen not because it looks best but because it can be dissolved off cleanly in fifty years without touching the original beneath. Every intervention is documented, photographed and designed to be undone by whoever comes next, who will know things the current conservator does not.
Our job is not to finish the painting. It is to make sure it is still here to be finished by someone who knows more.
Filling a loss without inventing one
Where paint is missing, the conservator fills it — but only within the exact boundary of the loss, and only with what the surrounding evidence supports. Where the evidence runs out, the fill stops. A hand missing three fingers stays missing three fingers.
It is a discipline built almost entirely on humility, which is a strange thing to find in a room full of masterpieces.
