Codex Ephraemi Rescriptus

Codex Ephraemi Rescriptus is an early 5th century Greek manuscript of the Bible, the last in the group of the four great uncial manuscripts of the Greek Bible (see Codex Sinaiticus, Codex Alexandrinus and Codex Vaticanus). It receives its name, as a codex in which the treatises of Ephraem the Syrian, in Greek translations, were written over ("rescriptus") a former text that had been washed off its vellum pages, thus forming a palimpsest. The later text was produced in the 12th century. The effacement of the original text was incomplete, fortunately, for beneath the text of Ephraem are the remains of what was once a complete Bible, containing both the Old Testament and the New. It forms one of the codices for textual criticism on which the Higher criticism is based.
