This article addresses the relationship between southern African San myth and rock art. Three nineteenth-century | Xam San narratives, recorded verbatim, are shown to contain specifiable entities of meaning, here dubbed ‘nuggets’, that are easily misunderstood or missed entirely. Each performance of a myth developed or abbreviated the significances of these ‘nuggets’ as the narrator tailored the story to suit the social, political and economic circumstances of the moment. Similarly, San rock art contains painted ‘nuggets’ that, for the San, situated the panels in one way or another at the interface between existential realms. Each in its own way, certain tales and images both played a social role by emphasizing the functions of ritual specialists who were believed to move between realms as they healed the community of physical, economic and social ills, especially tension between affines.
