carnation of the spirit of Nyakang, the semi-divine hero who founded the dynasty and settled the tribe in their present territory. It is a fundamental article of the Shilluk creed that the spirit of the divine or semi-divine Nyakang is incarnate in the reigning king, who is accordingly himself invested to some extent with the character of a divinity. But while the Shilluk hold their kings in high, indeed religious reverence and take every precaution against their accidental death, nevertheless they cherish "the conviction that the king must not be allowed to become ill or senile, lest with his diminishing vigour the cattle should sicken and fail to bear their increase, the crops should rot in the fields, and man, stricken with disease, should die in ever-increasing numbers." To prevent these calamities it used to be the regular custom with the Shilluk to put the king to death whenever he showed signs of ill-health or failing strength. One of the fatal symptoms of decay was taken to be an incapacity to satisfy the sexual passions of his wives, of whom he has very many, distributed in a large number of houses at Fashoda. When this ominous weakness manifested itself, the wives reported it to the chiefs, who are popularly said to have intimated to the king his doom by spreading a white cloth over his face and knees as he lay slumbering in the heat of the sultry afternoon. Execution soon followed the sentence of death. A hut was specially built for the occasion: the king was led into it and lay down with his head resting on the lap of a nubile virgin: the door of the hut was then walled up; and the couple were left without food, water, or fire to die of hunger and suffocation. This was the old custom, but it was abolished some five generations ago on account of the excessive sufferings of one of the kings who perished in this way. It is said that the chiefs announce his fate to the king, and that afterwards he is strangled in a hut which has been specially built for the occasion.
From Dr. Seligman's enquiries it appears that not only was the Shilluk king liable to be killed with due ceremony at the first symptoms of incipient decay, but even while he was yet in the prime of health and strength he might be attacked at any time by a rival and have to defend his crown in a combat to the death. According to the common Shilluk tradition any son of a king had the right thus to fight the king in possession and, if he succeeded in killing him, to reign in his stead. As every king had a large harem and many sons, the number of possible candidates for the throne at any time may well have been not inconsiderable, and the reigning monarch must have carried his life in his hand. But the attack on him could only take place with any prospect of success at night; for during the day the king surrounded himself with his friends and bodyguards, and an aspirant to the throne could hardly hope to cut his way through them and strike home. It was otherwise at night. For then the guards were dismissed and the king was alone in his enclosure with his favourite wives, and there was no man near to defend him except a few herdsmen, whose huts stood a little way off. The hours of darkness were therefore the season of
