The Typo That Undid a Papyrus

What eventually broke the case was philology, not chemistry. Laboratory tests on the fragment's papyrus and ink in 2014 found nothing conclusively modern, a result some initial coverage read as support for the fragment's authenticity. What those tests could not detect was a forger's use of a modern reference tool. Careful comparison of the fragment's Coptic against a freely available online interlinear edition of the Gospel of Thomas, the kind of resource a forger without deep independent command of Coptic grammar might lean on, showed the Jesus's Wife fragment reproducing patterns and apparent line breaks specific to that particular online transcription rather than to any manuscript tradition.

The investigative journalist Ariel Sabar took the case further, identifying the fragment's previously anonymous owner as Walter Fritz, a German-born former Egyptology student with a documented history of self-invention and fabricated credentials, and laying out the full chain of circumstantial and textual evidence in his 2020 book. Karen King, who had presented the fragment cautiously in 2012 and continued defending its plausibility for several years afterward, publicly stated following Sabar's reporting that the evidence now pressed in the direction of forgery, a rare and notable instance of a scholar revising a high profile public claim once the case against it became decisive.
