(M16) 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. Yet the divine spirit, as Dr. Seligmann justly observes, is clearly not thought of as congenital in the members of the royal house; it is only conveyed to each king on his accession by means of the mysterious object called Nyakang, in which, as Dr. Seligmann with great probability conjectures, the holy spirit of Nyakang may be supposed to reside. 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 shews 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 it is still in full vigour and has not yet been impaired by the weakness of disease and old age. In this connexion the particular symptom which is commonly said to seal the king’s death-warrant is highly significant; when he can no longer satisfy the passions of his numerous wives, in other words, when he has ceased, whether partially or wholly, to be able to reproduce his kind, it is time for him to die and to make room for a more vigorous successor. Taken along with the other reasons which are alleged for putting the king to death, this one suggests that the fertility of men, of cattle, and of the crops is believed to depend sympathetically on the generative power of the king, so that the complete failure of that power in him would involve a corresponding failure in men, animals, and plants, and would thereby entail at no distant date the entire extinction of all life, whether human, animal, or vegetable. No wonder, that with such a danger before their eyes the
