The Codex Ephraemi Rescriptus (Paris, National Library of France, Greek 9) is a manuscript of the Greek Bible, written on parchment. It is designated by the siglum C or 04 in the Gregory-Aland numbering of New Testament manuscripts, and δ 3 (in the von Soden numbering of New Testament manuscripts. It contains most of the New Testament and some Old Testament books, with sizeable portions missing. It is one of the four great uncials (these being manuscripts which originally contained the whole of both the Old and New Testaments). The manuscript is not intact: its current condition contains material from every New Testament book except 2 Thessalonians and 2 John; however, only six books of the Greek Old Testament are represented. It is not known whether 2 Thessalonians and 2 John were excluded on purpose, or whether no fragment of either epistle happened to survive.
The manuscript is a palimpsest, with the pages being washed of their original text, and reused in the 12th century for the Greek translations of 38 treatises composed by Ephrem the Syrian, from whence it gets its name Ephraemi Rescriptus.
