"Ring of the Nibelung" - Robert Wagner

I was playing through Shadow Hearts: Covenant and I started to read through the descriptions of the scene's in Robert Wagner's Opera, Ring of the Nibelung. Well, I decided I would Google "Nibelung" and it came up with some info about the book/Opera, so I was wondering if it is worth the read. I mean, come on, it's been referanced in Bugs Bunny cartoons :cool: . It looks pretty interasting, I think.

EDIT: Richard, not Robert.
