It is one of the four great uncial codices and contains the oldest complete copy of the New Testament. Discovered by Constantin von Tischendorf in 1844, it remains one of the most important Greek texts for biblical scholarship.

It contains the 'Freer Logion', a unique insertion after Mark 16:14 not found in any other manuscript. It is considered the third oldest Gospel parchment codex in the world and its style changes across different sections, suggesting it was pieced together from several different manuscripts.

Codex Alexandrinus is one of the four Great uncial codices and among the earliest and most complete manuscripts of the Bible. It is the oldest manuscript to use larger letters to indicate new sections, and it was the first manuscript of great importance and antiquity to be extensively used by textual critics.

Codex Bezae Cantabrigiensis is a highly important bilingual (Greek/Latin) uncial manuscript of the Gospels and Acts. It is the primary witness to the 'Western' text-type, and is the oldest surviving manuscript witness to the Pericope Adulterae (John 7:53-8:11).

This codex contains a complete text of the four Gospels. It is written in two columns per page with only 8 lines per page in uncial letters.

It contains a double ending for the Gospel of Mark. Textual critic F.H.A. Scrivener described it as 'by far the most remarkable document of its age and class' despite noting it was 'carelessly written by an ignorant scribe'.

Codex Basilensis is probably the oldest manuscript containing an almost complete text of the Gospels. Three of its leaves are palimpsests that were overwritten by a later hand, and it features early systems of dividing the gospels into referential sections.

It is one of the few uncial manuscripts with the complete text of the four Gospels. The manuscript features frequent insertion of an interpunction mark, suggesting it may have been copied from an ancient stichometrical style of writing.
