A POINT to notice about the temporary kings described in the foregoing chapter is that in two places (Cambodia and Jambi) they come of a stock which is believed to be akin to the royal family. If the view here taken of the origin of these temporary kingships is correct, we can easily understand why the king's substitute should sometimes be of the same race as the king. When the king first succeeded in getting the life of another accepted as a sacrifice instead of his own, he would have to show that the death of that other would serve the purpose quite as well as his own would have done. Now it was as a god or demigod that the king had to die; therefore the substitute who died for him had to be invested, at least for the occasion, with the divine attributes of the king. This, as we have just seen, was certainly the case with the temporary kings of Siam and Cambodia; they were invested with the supernatural functions, which in an earlier stage of society were the special attributes of the king. But no one could so well represent the king in his divine character as his son, who might be supposed to share the divine afflatus of his father. No one, therefore, could so appropriately die for the king and, through him, for the whole people, as the king's son.
We have seen that according to tradition, Aun or On, King of Sweden, sacrificed nine of his sons to Odin at Upsala in order that his own life might be spared. After he had sacrificed his second son he received from the god an answer that he should live so long as he gave him one of his sons every ninth year. When he had sacrificed his seventh son, he still lived, but was so feeble that he could not walk but had to be carried in a chair. Then he offered up his eighth son, and lived nine years more, lying in his bed. After that he sacrificed his ninth son, and lived another nine years, but so that he drank out of a horn like a weaned child. He now wished to sacrifice his only remaining son to Odin, but the Swedes would not allow him. So he died and was buried in a mound at Upsala.
