Provides a readable interpretation of the sequence of rock carving on the outcrop arising from an excavation by Clive Waddington in 2004.
Rock surfaces carved in the early Neolithic (Phase 1) were later partially quarried and new symbols applied to the exposed surfaces. The Phase 2 carvings are more varied but more crudely executed and take less account of the rock surface. Shortly after they were made, it is likely that they were covered by a cairn incorporating an Early Bronze Age burial cist positioned in a cleft between massive slabs of quarried rock, some with the ancient cup and ring markings. At a much later stage, the outcrop and cairn was embedded into field boundaries of the Iron Age or Romano-British period which may have been partly protective from more extensive quarrying.
The changes in carving between the two phases may imply that the original significance had been lost by the Bronze Age but the power of an already ancient place was adopted to provide a ceremonial monument for the dead.
