office he bore the title of Zoganes.(349) This custom might perhaps have been explained as merely a grim jest perpetrated in a season of jollity at the expense of an unhappy criminal. But one circumstance—the leave given to the mock king to enjoy the king’s concubines—is decisive against this interpretation. Considering the jealous seclusion of an oriental despot’s harem we may be quite certain that permission to invade it would never have been granted by the despot, least of all to a condemned criminal, except for the very gravest cause. This cause could hardly be other than that the condemned man was about to die in the king’s stead, and that to make the substitution perfect it was necessary he should enjoy the full rights of royalty during his brief reign. There is nothing surprising in this substitution. The rule that the king must be put to death either on the appearance of any symptom of bodily decay or at the end of a fixed period is certainly one which, sooner or later, the kings would seek to abolish or modify. We have seen that in Ethiopia, Sofala, and Eyeo the rule was boldly set aside by enlightened monarchs; and that in Calicut the old custom of killing the king at the end of twelve years was changed into a permission granted to any one at the end of the twelve years’ period to attack the king, and, in the event of killing him, to reign in his stead; though, as the king took care at these times to be surrounded by his guards, the permission was little more than a form. Another way of modifying the stern old rule is seen in the Babylonian custom just described. When the time drew near for the king to be put to death (in Babylon this appears to have been at the end of a single year’s reign) he abdicated for a few days, during which a temporary king reigned and suffered in his stead. At first the temporary king may have been an innocent person, possibly a member of the king’s own family; but with the growth of civilisation the sacrifice of an innocent person would be revolting to the public sentiment, and accordingly a condemned criminal would be invested with the brief and fatal sovereignty. In the sequel we shall find other examples of a dying criminal representing a dying god. For we must not forget that, as the case of the Shilluk kings clearly shews,(350) the king is slain in his character of a god or a demigod, his death and resurrection, as the only means of perpetuating the divine life unimpaired, being deemed necessary for the salvation of his people and the world.
