Buffalo mask (sigma)
- Vagala peoples, Nyamase group
- 20th–mid 20th century
Carved in the form of a highly stylized buffalo, this mask is viewed simultaneously from the front and rear. The mask is worn diagonally on the head. Locals describe the projecting beaklike form as a tail.
Sigma masks appear in the Simma masquerade performed by farmers at funeral celebrations and when a community's well-being is threatened, for example, by a drought or malevolent spirits.
