This mask, used by the Eastern Pende people of the DRC is known as panya ngombe and represents a buffalo, symbol of authority and dignity. Characteristic of this type are a horizontally oriented form, protruding ears, and an ornament consisting of a motif of relief triangles. These masks formerly belonged to the insignia of important chiefs (mbuya jia ufumu). Clad in a royal garment and holding a machete, the masked dancers appeared only during the mukanda initiation of adolescent boys after their circumcision, to gather donations to cover the cost of the celebration that took place after the initiation period. After circumcision in the context of initiation was abandoned back in 1930s, similar masks are today still incorporated in the lintel of the door to the royal treasure house where royal masks and other regalia are kept. These masks are therefore flat as they must conform to the shape of the lintel of the house and not to the face of the dancer.
