The neverending story? Metatext in Princess Tutu episode 17

This post started out as a comment that I intend to post on Mark Watches later today, when Mark and his commenters discuss Princess Tutu episode 17 (Crime and Punishment).

I tracked down the source of a page of German text on a book Fakir reads in Ep. 17. Drosselmeyer didn't write it. Neither did the Princess Tutu screenwriters. ( Evidence is behind the cut, along with awful Google Translate German translations that I'd love help with. )

I thought I knew how metatextual Princess Tutu could get. I was wrong.
