A Greek Manuscript Used as a Hiding-Place?

Having twice found evidence of pairs of medieval(?) spectacles left between the leaves of medieval manuscripts (described in the blog posts here and here) I now have a comparable, but somewhat different, situation to share.

In the previous posts I suggested that if a person only needed glasses for reading, it made perfect sense for him/her to leave the glasses in the book, both to act as a book-mark, and to make sure that they could be found when next needed.
