Relining—attaching a new canvas to the back of an original—was one of the most common conservation treatments applied to oil paintings from the 17th through early 20th centuries. While relining can stabilize brittle, torn, or structurally weak canvases, it also affects originality, surface texture, value, and how authenticity is interpreted.
