peril for the king. It is said that he used to pass them in constant watchfulness, prowling round his huts fully armed, peering into the blackest shadows, or himself standing silent and alert, like a sentinel on duty, in some dark corner. When at last his rival appeared, the fight would take place in grim silence, broken only by the clash of spears and shields, for it was a point of honour with the king not to call the herdsmen to his assistance.
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. 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.
In general the principal element in the religion of the Shilluk would seem to be the worship which they pay to their sacred or divine kings, whether dead or alive. These are believed to be animated by a single divine spirit, which has been transmitted from the semi-mythical, but probably in substance historical, founder of the dynasty through all his successors to the present day. Hence, regarding their kings as incarnate divinities on whom the welfare of men, of cattle, and of the corn implicitly depends, the Shilluk naturally pay them the greatest respect and take every care of them; and however strange it may seem to us, their custom of putting the divine king to death as soon as he shows signs of ill-health or failing strength springs directly from their profound veneration for him and from their anxiety to preserve him, or rather the divine spirit by which he is animated, in the most perfect state of efficiency: nay, we may go further and say that their practice of regicide is the best proof they can give of the high regard in which they hold their kings. For they believe, as we have seen, that the king's life or spirit is so sympathetically bound up with the prosperity of the whole country, that if he fell ill or grew senile the cattle would sicken and cease to multiply, the crops would rot in the fields, and men would perish of widespread disease. Hence, in their opinion, the only way of averting these calamities is to put the king to death while he is still hale and hearty, in order that the divine spirit which he has inherited from his predecessors may be transmitted in turn by him to his successor while
