Richard Wagner did not set out to stage Norse mythology. He set out to build a total work of art from it, and the difference shows most clearly in what happened to Odin. Under his German name Wotan, Wagner's chief god drives the entire cycle: he schemes across four operas and multiple generations to recover a stolen ring of power, fathers mortal children to work around his own broken oaths, and ultimately allows the world he rules to burn rather than surrender what he has built. Two independent readings of the cycle, a peer reviewed article in Christian Scholar's Review by Ronald Witzke and an essay for A Journey through NYC Religions by Tony Carnes, agree on the same underlying point from different directions: this Wotan is not simply Odin under a German name. He is a considerably more calculating, more morally compromised figure than the Eddas and sagas present.
The ending carries the clearest departure. In the Eddas, Ragnarok, the twilight of the gods, is followed by renewal: a new world rises from the sea, green and reborn. Wagner's Gotterdammerung stops at the destruction, with no reborn world following onstage. Witzke's article traces this to Wagner reshaping his sources through the structure of Greek tragedy, patterned, in the article's own words, after the Oresteia, to carry philosophical concerns, Neo-Platonic and panentheistic ideas about a divine order educating itself out of existence, that the Old Norse material never held.
Carnes reads the same choice as a deliberate act of secularization: Wagner wanted, in his own stated terms, to have the gods leave the stage after educating mankind toward freedom. Either way, the Ring's Odin is a Romantic composer's Odin first, and Old Norse religion's Odin only at one remove.
