The great uncial codices or four great uncials are the only remaining uncial codices that contain (or originally contained) the entire text of the Bible (Old and New Testament) in Greek. They are the Codex Vaticanus in the Vatican Library, the Codex Sinaiticus and the Codex Alexandrinus in the British Library, and the Codex Ephraemi Rescriptus in the Bibliothèque nationale de France in Paris.
