No detailed study of Anuak cosmology has yet been published. In general, Anuak explanations and interpretations of personal misfortune call attention to a variety of spiritual agents who are thought to bring illness and ultimately death to human beings. Anuak are especially concerned with the capability of ghosts of the recently deceased to seek vengeance among the living. Only a small number of Anuak have professed Islam or Christianity in favor of their traditional religious customs and tenets. The Anuak were last visited by a professional anthropologist in the early 1950s. As a result, it is difficult to provide an authoritative depiction of their present society and culture.
