It looks like they are replacing the scroll with more familiar metaphors. Close a book, fold a letter.
In Modern German, a scroll would be, according to Wikipedia: Die Schriftrolle (auch Buchrolle oder Volumen genannt). I was curious to see which actual medieval terms for a scroll exist. I'm finding two forms and their variations: rodel, rotel, rödel; rolle, rulle...
So if a German version of either quote is used, it must be one that uses a rodel or rolle form. Of course it is possible that another word exists which I overlooked, but this seems to cover the most common ones.
