In this paper the author places the rock art of Uganda in context. It probably belongs to the Late Stone Age period to the Holocene and its symbolism may be interpreted in the light of later belief systems recorded amongst the historical Pygmy people. Pongo is the bark cloth used to make the distinctive loin cloths of men and aprons of women. Pongo are probably depicted in the rock art to evoke the fecundity of ndura, linking the real and supernatural within the Pygmy cosmos.
