Different kinds of bows are depicted in San art. From curved, comparatively straight and triple curved there are a variety of bows found in rock art.

Bushman beliefs suggest that bags had a special significance beyond everyday use. Their relation to trance metaphors is illustrated in San mythology, where parallels were drawn between getting into a skin bag and getting into an animal- that is, taking on its potency. Therefore, bags painted next to a dance or by themselves, are probably an indication of a trance experience.
