"If we hadn’t found a Louvre study of Egyptian wedding and land contracts, which were from the same time period and had ink similar to that used to record the Gospel of Judas, we would have had a much more difficult time discerning whether the gospel was authentic," said Joseph G. Barabe. A senior research microscopist at McCrone Associates, he led an analytical team of five scientists who worked on the project at McCrone, a consulting laboratory in microscopy and microanalysis in Westmont, Ill. "That study was the key piece of evidence that convinced us that the gospel ink was probably okay."
Barabe’s team was part of a multidisciplinary effort organized in 2006 by the National Geographic Society to authenticate the Gospel of Judas, which was discovered in the late 1970s after having been hidden for nearly 1,700 years. The text, written in Egyptian Coptic, is compelling because—unlike other Biblical accounts that portray Judas Iscariot as a reviled traitor—it suggests that Jesus requested that his friend, Judas, betray him to authorities.
