Wiessner's analysis of stylistic variation in San arrows entails valuable ethnoarchaeological observation and insight. But her evidence contradicts the iconological theory she imposes upon it, whereby San artisans are thought to purposefully invest their products with ethnic symbolism in order to transmit social information to various target populations. However, an alternative view, according to which the arrows simply exhibit the ethnic style latent in all isochrestic behavior (see Sackett 1982), is consistent both with their formal variation and with the commonplace ethnic symbolism that the San themselves are reported to read into them. This view also provides a more reasonable explanation than does the iconological theory of why stylistic distinctions fail to emerge among San bands engaged in risk-sharing strategies. In any event, isochrestism is the basic source of ethnic style in material culture. Iconicism is a special case and ought not be invoked unless specific expectations are met by the evidence.
