The sandstone outcrop that carries it protrudes just six centimetres above the surrounding earth, and vegetation has been quietly closing in from every side. What it holds, once found, is a single carefully worked motif: a cupmark, the kind of shallow circular depression, typically made by sustained pecking with a harder stone, that appears on prehistoric rock art across Atlantic Europe, enclosed here within a wide, dense ring of pickmarks roughly fifteen centimetres across in total. The combination is deliberate and considered, even if its original meaning has not survived alongside it.
