『古事記』의 構想 ―天孫의 神婚 譚과 天皇의 短命 起源―

Abstract

It is only three different intermediaries, the Kojiki and the Nihonshoki, that have carried the newlywed tradition of Tenson called banana type myth. Although the rock which is a daughter of a mountain god first, and the sister who symbolizes a flower, respectively were recommended as a bride in the newlywed myth, a groom resists an ugly elder sister, and only a younger sister chooses him, and he passes a night. Although it is the life origin tradition with the Kojiki and Nihonshoki same so far, unlike Tenson and the Nihonshoki which is man, the object is also adding the Emperor's life by the Kojiki. Thus, in the Kojiki, it is different original tradition from the Nihonshoki. In the newlywed tradition of the Kojiki, it seems that I was told using the two following elements. First, it is an element called special fortune-telling who asks transcendental God about judgment of saying "Ukehi". Although there is an example about many "Ukehi" in the Kojiki and Nihonshoki, it is only here to have been carried out in advance and the mountain god explains the reason for having seen off the sister as follows. That is, since the elder sister who guarantees an eternal life was resisted and the younger sister who is a goddess of a flower was chosen, the mountain god is saying that it caused a short life although prosperity was carried out. Thus, in the newlywed tradition of the Kojiki, posterity's prosperity was also told by “Ukehi” with the cause of the life. Next, the name of the Tenson “Hononinigi” is the soul of the grain which essentially repeats “death and rebirth.” Therefore, the matrimonial partner had to be “Konohananosakuyahime” which is a spirit of the flower instead of “Iwanagahime” which symbolizes a rock. As a bride suitable for Tenson which is the soul of grain in short, it was a flower which can bear not a rock but a fruit. Against the background of the above element, the Kojiki explains the life origin. By this, the Kojiki could also tell the sacredness of the Imperial Household's privilege and sovereignty while tying the Emperor's life to the age of the gods.
