The heroic substance is presented from a mythical-apocalyptical point of view that has much in common with the implication of inevitable fate in the Scandinavian myths.
Or, as written by Solveig Nordström in her essay about the Saga, “the birth of the myth in the spirit of language.”
The whole philosophy of Balder is heading towards a reflection on the interpretation of history as a basic mythical process; one that extends and conceives itself only as an interpretation of a new myth of redemption for the individual in its heroic dimension.
Thus, the poetics, the philosophy of language and the birth of the myth in the spirit of language. When Balder adds the research on the earliest Germanic language to his tetralogy about Arminius the Cheruscan is the moment he provides the Saga with its loftiest ingredient, the one that gives it unique character.
