What it is
Nggam refers to a system of divination where practitioners read the actions of small animals to gain insight. The method relies on observing creatures such as spiders or crabs. These animals are presented with a question, and their subsequent movements are analyzed. This practice appears across various communities in western Cameroon. It serves as a means for individuals to seek guidance or answers through the interpreted behavior of the chosen creature.
Where it comes from
The practice is documented among multiple ethnic groups in the region. Research highlights its use by the Mambila people in both Cameroon and Nigeria. Other groups, including the Yamba, Bekpak, and Bamileke, also employ this method. Studies have examined different variations, such as crab divination in northern areas. Linguistic surveys have mapped spider divination practices throughout Cameroon, showing its widespread nature.
How it is done
A diviner presents a query to an animal, typically a spider or a crab. The practitioner then watches how the creature moves or reacts. Specific behaviors are translated into meaningful responses for the asker. Videos recorded in Somié show these interactions in detail. The process involves careful observation and interpretation of the animal's natural actions to derive an answer.
Tools and materials
The primary tools are living animals, specifically spiders and crabs. No complex machinery is required. The focus remains entirely on the creature's physical actions. The diviner uses the animal itself as the medium for communication. Simple containers may be used to hold the creatures during the reading.
