Codex Ephraemi Rescriptus

The codex's earliest location is not securely known. It reached France in the sixteenth century through the Medici royal collection and is now held by the Bibliotheque nationale de France. Scholars gradually recognized the erased biblical writing beneath the Ephrem overtext. Earlier chemical attempts to increase contrast damaged portions, while Constantin von Tischendorf produced the first major edition of the New Testament undertext in the 1840s after sustained decipherment. Modern digital photography allows renewed examination without repeating invasive treatments, but every proposed letter still must account for both scripts and the parchment's condition.

The surviving object is a parchment codex whose visible twelfth-century minuscule overtext crosses a much older biblical majuscule undertext. The original leaves were disbound, washed or scraped, reordered, and written again, so the biblical sequence is fragmentary. Undertext columns, corrections, and occasional legible passages emerge unevenly beneath the later work. The name 'rescriptus' refers to this rewriting, and 'Ephraemi' to the upper text. What a viewer should notice is not one clean page of Scripture but two distinct bookmaking events sharing the same costly writing support centuries apart.

The biblical undertext is assigned palaeographically to the fifth century, while the reuse belongs to the twelfth. This places the first codex among the great late-antique Greek biblical majuscules and the second production within a medieval culture that valued the parchment enough to recycle it. The undertext's origin is broadly eastern Mediterranean rather than securely localized. Dating rests on handwriting and codicological comparison because the original colophon is lost. Reagent damage and variable legibility also mean that nineteenth-century editions and modern imaging must be critically compared instead of assuming every historical transcription is equally certain.
