When was this stone carved? Is it possible to be a little more specific than Prehistory, Stone - or Bronze Age?
Hardly! Why? Because:
- The absence of datable artifacts on or near the rock art sites
-The re-use of carved stones in Bronze Age funeral settings
 
In that case; is it possible to give a rough time bracket? Sure!

The Beginning
 

The Beginning; the Dalladies Cup-marked Slab
 
Above you see an image of a cup-marked slab, found during the excavation of the Dalladies long-barrow (NO 627673) in Fettercairn, Kincardineshire, NE Scotland. This long-barrow was excavated in 1971 by Mr Stuart Piggott. The sandstone slab (46x42cm) with 8 cup marks on the upper and a faint one on the other side, was found on the 'land-level' of the mortuary structure. In the same layer a plano-convex flint knife was found. The stone was covered with the remains of probably a former roof of Birch bark. This material could be dated by the C-14 radiocarbon method. Although there were some differences in the outcome of different research efforts, Stuart Piggott concludes that Dalladies long-barrow can be properly dated at 3390BC. The cup-marked stone must have been inserted around that time and that makes it the only really well dated example. An full account of the excavation and dating procedures can be found in the "Proceedings of the Society of Antiquaries of Scotland", Volume 104 (1971-1972), page 23.
 
The End
 
The End; Nether Largie North Cairn Slabs, Axes over Cups! (photo: May,2002)
 
At the Nether Largie North Cairn (NR 830 984), in Argyll, Scotland, there is a large cist capstone with cup-markings superimposed by axes. These axes are (status?) symbols of the Bronze Age. The fact that they were pecked over the cups may mean that the cups were not longer relevant to the Bronze Age people. The Bronze Age is a technological stage between the Stone and the Iron Ages, beginning in the Middle East about 4.500BC and lasting in Britain from about 2000 to 500BC. So around 2000BC the cup-and-ring motifs had lost there significance. This is of course a very rough guess. While the cups in Argyll were superimposed by axes, it is possible that a stone carver in Northumberland just started a new cup-and-ring motif. Nevertheless, we have defined our time bracket:
 
The open-air, abstract Rock Art Era in Britain:
 
3500-2000BC
 
So now we have our time-bracket answer, a lot of questions remain: 
 
- How was it possible that the specific abstract style was sustained over the ages?
- How many times did the meaning of the motifs change?
- Why are there but a few concrete carvings (deer, hands)?
- Were carvers not tempted to create an image of a tree, a face or an animal?
- Who controlled the discipline?
- How?

  A cup and four rings with outrunning groove.
It looks like the one on Weetwood Moor, Northumberland.
 
This one is in my backyard and datable!
The motif was chiseled out of a grave stone by my good neighbour
and amateur mason Ruud Uhl in 1999.
