Codex Claromontanus is a 5th or 6th-century Greek-Latin diglot manuscript containing the Pauline Epistles and Hebrews. It is notable for having Greek and Latin texts on facing pages and for containing an early stichometric catalogue of Old Testament books.

It is a palimpsest where the original 5th-century biblical text was washed off and overwritten in the 12th century with treatises by Ephrem the Syrian. It is one of the four great uncials, and its underlying text was famously deciphered by Constantin von Tischendorf in the 1840s.

Codex Augiensis is a 9th-century diglot uncial manuscript of the Pauline Epistles containing double parallel columns of Greek and Latin. It is noted for its strong textual relationship with Codex Boernerianus.

Contains an almost complete text of the Catholic and Pauline epistles. The manuscript features scholia at the foot of the pages attributed to John Chrysostom, and the uncial text is separated into paragraphs by comments written in minuscule script.

It contains large lacunae in Acts 1:1-8:10 and in Hebrews 13:10-25.

Uncial 049 is a 9th-century Greek New Testament codex containing the Acts of the Apostles and the Epistles with numerous lacunae.

It is a Greek/Latin diglot containing an Old Irish verse on folio 23v written by a disappointed pilgrim. The manuscript suffered severe water damage during World War II.
