Decorative Celtic Books

At https://phys.org/print432456033.html … excavations at a Viking site in Trondheim in Norway has uncovered a decorative fitting from a book pilfered from Ireland (or the Celtic fringe). It is gold plated on silver and seems to have come from a religious book – probably from a monastery in Ireland at some point in the 800s. Hence, such embellished books really did exist in the pre-Norman era, contrary to what is inferred in MJ Harper's book, Meetings with Remarkable Forgeries.
