(#52’s motival links, if any, not yet ascertained)
[[#53]] “Erda” – Mother Nature - invokes her objective knowledge of all that was, is, and shall be, that all things that are, end
(#53 based on #2, and therefore on #1; with some changes its inversion is basis for #54; #53’s chords are the basis for #138; through #1 it is related to #57b, basis for #83a and #146; #53's last three notes generate #71, #77, #88, #92, #95, and possibly #152)
[[#54]] Erda's prophecy of the fore-ordained “Twilight of the Gods”
It is fore-ordained by the laws of evolution and history that Alberich’s son Hagen (metaphor for our modern, secular, scientific world-view) will ultimately supplant the mytho-poetic, religious phase of human history, bringing about a figurative twilight of the gods
(#54 approximately based on inversion of #53; related through #53 to #1 and #2, #57b, #71, #77, #88, #92, #95, and perhaps #152)
[[#55]] Donner's cry: “Heda! Heda, hedo!”
Donner sweeps the gods’ heavens clear, in order to purify the air of the taint of Wotan’s corrupt machinations and self-deceit in establishing the gods’ self-delusional refuge from truth, Valhalla
(#55 basis of #61, and possibly basis of #84 and #85)
[[#56]] “Rainbow Bridge” over the Rhine to Valhalla
The Rainbow Bridge is the evolutionary bridge of transition from nature to human culture
