Masks usually represent clan ancestor figures. The men carve masks from soft wood. Paint is made from earth pigments and charcoal. Few masks are worn directly over the face, which explains the lack of holes for eyes. Other masks are made only for display in the menâs Haus to attract powerful and useful spirits. Masks often refer to a clan totem such as a crocodile or eagle. In the past a freshly procured human head was buried under each post when a Haus Tambaran was erected.
