god of the fights, Thor, plays the utilities here. He represents
rough force and thus resists to the lance of treaties.
He serves only for the representation of Wotan's aspect: the
turbulent tension, which accumulates gradually at the end
of the Rheingold, and at the beginning of Walküre.
He will be replaced later by the Walkyries,
the turbulent thick clouds. (Cf. Prelude of "Siegfried" III-rd act.)
