Missal of Silos
The Missal of Silos is the oldest known document on paper (as opposed to parchment) created in Europe; it dates to before 1080 AD. The manuscript was written on quarto; it comprises 157 folios, of which folios 1 to 37 are on paper and the rest are on parchment. Strictly speaking, it is not a missal: It has been described as a breviary-missal.
