The oldest known document or codex written on paper in Europe is the Missal of Silos.
A quarto comprised of 157 folios, of which folios 1-37 are on paper and the remainder on parchment. It has been described as a breviary-missal or a Liber Mysticus
or Breviarum gothicum
"The missal is "Codex 6
" held in the library of the Monastery of Santo Domingo de Silos
, Spain. It is one of a number of liturgical manuscripts of the Mozarabic rite
which have been preserved in the Silos library, despite the suppression of the rite in 1080 by Pope Gregory VII
. The codex is named after its current location in Silos, but it was not made at the Silos monastery's scriptorium
; it was made at the monastery of Santa María la Real of Nájera
. The paper for the missal is believed to have been manufactured in the Islamic world, probably Islamic Spain
, even though Nájera
was in Christian territory at the time the document was created" (Wikipedia article on Missal of Silos, accessed 9-2020).
