The first eight phases combine to form the Earlier Period, in which the art is entirely naturalistic and essentially produced by a hunting people; the later nine combine to form the Later Period, in which the art, on the whole, is degenerate, less naturalistic, and produced often by pastoral folk. Breuil recognises three geographical groups: Group I, Rhodesia; Group II, the Eastern Orange Free State and Western Basutoland; Group III, the Cape Province, and draws most illuminating comparisons between the various phases of the three groups
