The Lwalu (some sources use 'Lwalwa') in the Democratic Republic of the Congo and Angola are primarily known as mask makers. Sculptors occupy a privileged place in society (such as community chiefs) and are responsible for the initiation and circumcision of young men and boys. They are also responsible for creating the masks used by the ngongo (also called bangongo) secret society during these initiation ceremonies.
