In this paper we present results on the rock art painting materials from the Gode Roriso rock shelter, located in the eastern Hararghe region of Ethiopia. This analysis included X-microfluorescence, Micro-Raman spectroscopy and microstratigraphy. As far as the results of the analysis are concerned, a white natural wax (beeswax), carbon black and iron oxides (a mixture of haematite and magnetite) along with charcoal particles (forming as a red colourant) have been applied on a natural substrate constituted of granite containing feldspar crystalline forms. Although very much a science-based piece of research, the results have far-reaching outcomes for understanding the sequencing of pigment application.
