(M14) Like Nyakang himself, their founder, each of the Shilluk kings after death is worshipped at a shrine, which is erected over his grave, and the grave of a king is always in the village where he was born.(58) The tomb-shrine of a king resembles the shrine of Nyakang, consisting of a few huts enclosed by a fence; one of the huts is built over the king’s grave, the others are occupied by the guardians of the shrine. Indeed the shrines of Nyakang and the shrines of the kings are scarcely to be distinguished from each other, and the religious rituals observed at all of them are identical in form and vary only in matters of detail, the variations being due apparently to the far greater sanctity attributed to the shrines of Nyakang. The grave-shrines of the kings are tended by certain old men or women, who correspond to the guardians of the shrines of Nyakang. They are usually widows or old men-servants of the deceased king, and when they die they are succeeded in their office by their descendants. Moreover, cattle are dedicated to the grave-shrines of the kings and sacrifices are offered at them just as at the shrines of Nyakang. Thus when the millet crop threatens to fail or a murrain to break out among the cattle, either Nyakang himself or one of his successors on the throne will appear to somebody in a dream and demand a sacrifice. The dream is reported to the king, who thereupon at once sends a cow and a bullock to one or more of the shrines of Nyakang, if it was he who appeared in the vision, or to the grave-shrine of the particular king whom the dreamer saw in his dream. The bullock is then sacrificed and the cow added to the sacred herd belonging to the shrine. Further, the harvest ceremony which is performed at the shrines of Nyakang is usually, though not necessarily, performed also at the grave-shrines of the kings; and, lastly, sick folk send animals to be sacrificed as offerings on their behalf at the shrines of the kings just as they send them to the shrines of Nyakang.
