A long-lost gospel that casts Judas as a co-conspirator of Jesus, rather than a betrayer, was ruled most likely authentic in 2006.Now, scientists reveal they couldn't have made the call without a series of far more mundane documents, including Ancient Egyptian marriage licenses and property contracts.Since its first use in the 1940s radiocarbon dating has been the most accurate method of dating ancient objects and artifacts.Radiocarbon, present in living organisms, decays at a constant rate in dead tissue.No part of the ancient script was altered or damaged during this process. "The calibrated ages of the papyrus and leather samples are tightly clustered and place the age of the Codices within the third or fourth centuries A.The results allowed lab experts to confidently date the papyruses to between A. D.," reported Tim Jull, director of Arizona's AMS facility, and research scientist Greg Hodgins.

Additionally, with works of art on paper, we do not often have an expendable sample for this type of analysis.
Unlike the Fourier-Transform Infrared Spectroscopy and X-ray Fluorescence Spectroscopy described in the two previous posts which require no sample and were used to investigate pigments and adhesives used on the papyrus, C-14 dating requires a sample from the object, usually about 5 mg, which is destroyed during testing.
