"Tony, Tony, come around, something’s lost and can’t be found!" Some manuscripts require more than just manual skills to succeed in their conservation, and so we prayed to Saint Anthony to help us unlocking the bookbinding, whose key had been lost forever. Certainly not many renaissance bookbindings have an iron safety lock in their covers and thus this extra holly help was deemed quite necessary. The prayer didn't provide any key, but at least a satisfactory conservation solution was achieved!
