The sona tradition belongs to the culture of the Cokwe and related peoples in Eastern Angola and neighboring areas of Northwest Zambia and the Congo. Observers have described sona as sand graphs, sand drawings, drawings in the sand, writing in the sand, pictographs and ideograms, and as a system of communication. This volume by Paulus Gerdes, an ethnomathematician, shows that mathematical considerations were involved and developed as the Cokwe invented sona and built up a reservoir of symbolic-graphic expressions.
