The existence of the text was made public by former professor at the University of Geneva Rodolphe Kasser at a conference of Coptic specialists in Paris, July 2004. In a statement issued March 30, 2005, a spokesman for the Maecenas Foundation announced plans for edited translations into English, French, German, and Polish once the fragile papyrus had undergone conservation by a team of specialists in Coptic history to be led by Kasser, and that their work would be published in about a year. A. J. Tim Jull, director of the National Science Foundation Arizona AMS laboratory, and Gregory Hodgins, assistant research scientist, announced that a radiocarbon dating procedure had dated five samples from the papyrus manuscript from 220 to 340 in January 2005 at the University of Arizona. This puts the Coptic manuscript in the 3rd or 4th centuries, a century earlier than had originally been thought from analysis of the script. In January 2006, Gene A. Ware of the Papyrological Imaging Lab of Brigham Young University conducted a multi-spectral imaging process on the texts in Switzerland, and confirmed their authenticity. Joseph Barabe presented the behind-the-scenes story of the role an analysis of the ink played in authenticating the book at an American Chemical Society meeting.
