Dr. Daniel B. Wallace of the Center for the Study of New Testament Manuscripts (CSNTM) describes the decay of the most important NT palimpsest – Codex Ephraemi Rescriptus. Constantin Von Tischendorf and others have transcribed it previously, but the introductory verses to each book have faded. Multi-spectral and UV photography may save the red letters, but a chemical used 170 years ago to read the hidden text better has given the codex only a little more time to live.
