The Wajapi of the Tupi-guarani cultural-linguistic group are indigenous to the northern Amazonian region. Some 580 Wajapi live in 40 small villages on a specially designated territory in the state of Amapá. The Wajapi have a long history of using vegetable dyes to adorn their bodies and objects with geometric motifs. Over the centuries, they have developed a unique communication system – a rich blend of graphic and verbal components – that reflects their world-view and enables them to hand down knowledge about community life.
