The Ngil (ni - jil) mask originated from an agrarian/hunting group known as the Fang people, located in the countries of Gabon, Equatorial Guinea, and Cameroon.
The white color of these masks is associated with things like the spirits of ancestors, death, and male virility or manhood.
One of the defining characteristics are high rounded brows and a smooth, long face which may have meant to reflect the Ngil Society's name, which means "gorilla".
The Ngil were a secret male society within the Fang people tasked with protecting and administering justice, as well as keeping peace between clans and villages.
[3] The Ngil society took part in rituals and ceremonies that were intended to discourage people of the community that might have evil intentions and fight off witchcraft.
