Adaptation or Aesthetic Alleviation: Which Kind of Evolution Do We See in Saharan Herder Rock Art of Northeast Chad?

Abstract

During the middle and late Holocene, the prehistoric inhabitants of the Sahara articulated their agency under conditions of aridification in part through aesthetic symbolic behaviour that became petrified, as it were, in ubiquitous rock art. Rock art, predominantly depicting domestic animals, continued to be produced throughout the later Holocene, despite deteriorating environmental conditions that necessitated other adaptive strategies. Artistic production appears to have ignored the environmental changes and evolved an aesthetic that, initially, celebrated animals for the function for which they were domesticated and, subsequently, for their looks, symbolic capital and potential to express status. In the most recent periods, art production evolves into a symbolism that is entirely based on, and communicated through, camel imagery.
