Stephen Emmel, a professor of Coptology at the University of Muenster … questioned whether the document was authentic.
"There's something about this fragment in its appearance and also in the grammar of the Coptic that strikes me as being not completely convincing somehow," he said in an interview on the sidelines of the conference.
Another participant at the congress, Alin Suciu, a papyrologist at the University of Hamburg, was more blunt. "I would say it's a forgery. The script doesn't look authentic" when compared to other samples of Coptic papyrus script dated to the 4th century, he said.
Despite concerns about how the fragment surfaced on the market, there is the predictable comment:
AnneMarie Luijendijk, the Princeton University expert whom King consulted to authenticate the papyrus, said the fragment fit all the rules and criteria established by the International Association of Papyrologists. She noted that papyrus fragments frequently don't have a provenance, simply because so many were removed from Egypt before such issues were of concern. She acknowledged the dilemma about buying such antiquities but said refraining from publishing articles about them is another matter.
