Beza's Codex (sometimes called the Codex Cantabrigiensis, from its present place of deposit, the university of Cambridge, England), a very ancient MS. on vellum, containing in its present state the four Gospels and Acts, but with several omissions. It is usually cited by critics as MS. D of the Gospel and Acts. In the arrangement of the Gospels John stands second. It contains the Greek text with a Latin translation on opposite pages. It is written in large uncial letters, and is generally assigned to the 6th century; but there are some additions which cannot be earlier than the 10th century. It forms a quarto volume of 10 inches by 8, and now consists of 414 leaves. Originally, as is shown by the paging, there were at least 512 leaves. The principal hiatus is between the Gospels and Acts, which it is presumed was occupied by the Epistles. Its critical authority is not ranked high. It is chiefly remarkable for extensive interpolations, which amount in Acts alone to more than 600. The MS. was presented in 1581 to the university of Cambridge by Theodore Beza, who said that it was found in the monastery of St. Irenaeus at Lyons, whence it had probably been taken by some Huguenot soldier.

The MS. has been several times carefully collated, and has been twice printed, once by Kipling in facsimile (Codex Bezw Cantabrigiensis, 2 vols, fol., 1793), and later in ordinary type with an introduction and annotations (8vo, London, 1864).
