a spear "to keep at bay the spirits which might try to sneak into the old chief's body by the same road as the beer." The same motive of warding off evil spirits probably explains the custom observed by some African sultans of veiling their faces. The Sultan of Darfur wraps up his face with a piece of white muslin, which goes round his head several times, covering his mouth and nose first, and then his forehead, so that only his eyes are visible. The same custom of veiling the face as a mark of sovereignty is said to be observed in other parts of Central Africa. The Sultan of Wadai always speaks from behind a curtain; no one sees his face except his intimates and a few favoured persons.
§ 4. Taboos on Quitting the House.—By an extension of the like precaution kings are sometimes forbidden ever to leave their palaces; or, if they are allowed to do so, their subjects are forbidden to see them abroad. The fetish king of Benin, who was worshipped as a deity by his subjects, might not quit his palace. After his coronation the king of Loango is confined to his palace, which he may not leave. The king of Onitsha "does not step out of his house into the town unless a human sacrifice is made to propitiate the gods: on this account he never goes out beyond the precincts of his premises." Indeed we are told that he may not quit his palace under pain of death or of giving up one or more slaves to be executed in his presence. As the wealth of the country is measured in slaves, the king takes good care not to infringe the law. Yet once a year at the Feast of Yams the king is allowed, and even required by custom, to dance before his people outside the high mud wall of the palace. In dancing he carries a great weight, generally a sack of earth, on his back to prove that he is still able to support the burden and cares of state. Were he unable to discharge this duty, he would be immediately deposed and perhaps stoned. The kings of Ethiopia were worshipped as gods, but were mostly kept shut up in their palaces. On the mountainous coast of Pontus there dwelt in antiquity a rude and warlike people named the Mosyni or Mosynoeci, through whose rugged country the Ten Thousand marched on their famous retreat from Asia to Europe. These barbarians kept their king in close custody at the top of a high tower, from which after his election he was never more allowed to descend. Here he dispensed justice to his people; but if he offended them, they punished him by stopping his rations for a whole day, or even starving him to death. The kings of Sabaea or Sheba, the spice country of Arabia, were not allowed to go out of their palaces; if they did so, the mob stoned them to death. But at the top of the palace there was a window with a chain attached to it. If any man deemed he had suffered wrong, he pulled the chain, and the king perceived him and called him in and gave judgment.
§ 5. Taboos on Leaving Food over.—Again, magic mischief may be wrought upon a man through the remains of the food he has partaken of, or the dishes out of which he has eaten. On the principles of sympathetic magic a real connexion continues to subsist between the
