The great age for the discovery of papyrus manuscripts in Egypt was of course the late nineteenth and early twentieth century. But a handful of papyrus manuscripts, more specifically Latin papyrus codices, also survived from antiquity in European libraries.
In his paleographical handbook published in 1893, Edward Maunde Thompson gave a list of these. As it turns out, images of most of them are available online:
Avitus, Sermons and letters (Paris, BnF Lat. 8913 and 8914; CLA 573)
Augustine, Sermons and letters (Paris, BnF Lat. 11641; Geneva Ms Lat. 16; St. Petersburg, Russian National Library Lat. F. I. 1; CLA **614)
Hilary, De trinitate (Vienna, Austrian National Library Cod. 2160*; Vatican Library, Barberini Lat. 9916 (one folio); Sankt Florian Austria Stiftsbibliothek III.15.B (one folio); CLA 1507)
Josephus, Antiquities (the so-called Ambrosianus papyraceus; Milan, Biblioteca Ambrosiana Cimelio 1; CLA 304)
Isidore of Seville, Synonyma and Eusebius Gallicanus, Sermons (Sankt Gallen Stiftsbibliothek 226; Zürich Zentralbibliothek RP 5-6; CLA 929)
Codex traditionum ecclesiae Ravennatis (Munich, Bayerische Staatsbibliothek Clm 44)
Justinian’s Digest (Pommersfelden, Bibliothek Graf von Schönborn PPL 1–6; CLA 1351)
We’re happy to be informed of other similar papyrus codices not noted by Thompson.
