“The symbols on the Goggleby stone are a shallow wide cup mark with smaller one beneath it on the vertical face of the stone. The Asper’s Field stone, leaning inwards now towards the avenue, has a cup with a single ring on top....
The fact that the symbols are used on a very long ceremonial avenue may link them to the ritual of the avenue”.
