The prehistoric rock art of Great Britain — England, Scotland and Wales — is surveyed, with specific reference to the over 900 sites bearing motifs more complex than cup-marks alone and apparently random grooves. Of sites bearing cup-marks alone, there are at least 700.
The majority of motifs is geometric, with a few animals, weapons and human hands and footprints. Two main groups are recognized, the Boyne or Passage Grave type and the Galician type. The former occurs mainly on the slabs of Neolithic tombs, especially in Ireland, and includes spirals, rings, lozenges, zigzags and flower-like figures, only some of which occur in Britain. The latter is more restricted in design, with mainly cup-and-rings, rings, and spirals, usually on rock outcrops and boulders. A third group is recognized by some workers, in which cist and burial stones are carved with mostly the Boyne type, but sometimes with Galician or simple cup-marks or a mixture of these. There is also occasional overlap between Galician and Boyne types, occurring on natural rocks and tombs.
The main characteristics, locations in relation to topography and archaeology, and distribution are detailed. Dating and significance are briefly discussed.
Most of the art occurs in a central belt of Britain, but within that it is recognized as being distributed spatially among 16 main regions which are defined both geographically and with regard to concentrations of sites.
There is a gazetteer of all sites, similarly arranged.
