In southwestern Cameroon and the neighboring Nigerian territories lives the Ekoi group, which comprises various tribes settled in the interior of the lush virgin forest, at the level of the middle course of the Cross River: the Keaka, the Anyang, the Banyang, the Obang, the Boka, and others. The Ekoi like to call themselves Ejagham. The absolute dominance of secret societies and the environment, virgin forest, gives these peoples relatively uniform cultural characteristics. The origin of their masks, marked by realism, comes from the custom of the ancient Ekoi headhunters. The victors used to tie the heads of their dead enemies to their own heads and then, drunk with the conquest they had achieved, throw themselves into frenzied dances. According to a deep-rooted belief, the blood of the defeated enemies had the power to fertilize the fields. Wooden heads, usually covered with skin, later replaced human heads, but faithfully assumed their characteristics. It is a double-helmet mask, with a male face with closed eyes, although with a small slit so that the wearer can see, and a female face with open eyes, representing the dualism between life and death.
