Codex Dublinensis is a Greek uncial manuscript of the New Testament Gospels, written on parchment.

[2] The original parchment was purplish in colour, rather thin, and the writing on one side shows through to the other in many places, and there are many holes present.

[3]: 4  The manuscript has been rebound at some point between 1801 and 1853, to which biblical scholar Samuel Tregelles decries: The binder simply seems to have known of the Greek book in the cursive letters, which are all black and plain to the eye.

And so the pages have been unmercifully strengthened in parts, by pasting paper or vellum over the margins, leaving indeed the cursive writing untouched, but burying the uncial letters, of so much greater value... Also in places there were fragments all rough at the edges of the leaves, and these have been cut away so as to make all smooth and neat ; and thus many words and parts of words read by Dr. Barrett are now gone irrecoverably.

[6][3]: 8  The conventional nomina sacra are present, with several sometimes being written out in full (μητηρ / mother, ουρανος / heaven/sky, ανθρωπος / man/human, and υιος / son).

[7] The Greek text of this codex is considered a representative of the Alexandrian text-type, with many alien readings.

[4] Textual critic and biblical scholar Kurt Aland placed it in Category III of his New Testment manuscript classification system.
