Walkure on the Bayreuth broadcast for the Sunday late afternoon/evening. Rheingold was in the Starbucks across from the national parliament, which went from daytime to nighttime lighting at the finish, which was quite powerful. But for the first day of the festival, the rooms adjacent to the busy road. Sufficient for the wanderer.
In this listening, I'm seeing Wotan as a sort of protestant figure. (Much to do with the reading of the past year, perhaps.) Building Valhalla against the ones who have gained spiritual power by renouncing earthly love. Walhall seems a more contingent proposition -- not a universal heaven, but a collection of the noble souls that Wotan's Valkyries are able to capture (St. Michael figures, perhaps) after Wotan had intentionally made the mortals' lives difficult and quarrelsome. Built by the human giants, not by the Gods. And he fears that the armies of the ones who have renounced love might even reach these souls that have been taken there and convert them.
And the ending with the Valkyrie who disobeyed him, even though entirely a creature of his will -- perhaps reckoning the cost of reformation, and attempting to ensure that its spirit will reach the future?
More things in heaven and earth, Horatio. Particularly earth.
