Anjenu are the nature-spirits of the rivers and the bush in Idoma religion, among the lesser divinities standing below the supreme Owoicho. Conceived chiefly as female, they are protective yet capricious powers: they appear to people in dreams, are blamed for infertility and ill-health, and are at the same time petitioned to grant children and to cure sickness. Men invoked them to make their wives conceive, and women appease them with offerings of bottled river water and calabash gourds. Their shrines characteristically hold sacred water, the eka medicine calabash, sacrificial food, and frequently a carved wooden image of the spirit, sometimes accompanied by a mud figure of a lion or leopard. The Anjenu cult is religiously and artistically hybrid, drawing together the Hausa bori possession spirits, the Igala alijenu and the pan-African water-deity Mami Wata; its sculptures, documented by Sidney Kasfir and held in major collections such as the Metropolitan Museum of Art, are a celebrated genre of Idoma art carved by named masters including Oklenyi of Okungaga.
