ジョルジュ・デュメジル
The king as the high priest would have been the central figure in establishing favourable relations with the other world. Georges Dumézil suggested that the religious function was represented by a duality, one reflecting the magico-religious nature of priesthood, while the other is involved in religious sanction to human society (especially contracts), a theory supported by common features in Iranian, Roman, Scandinavian and Celtic traditions.
