Another scholar, Charles Hedrick, who recently retired from Missouri State University, saw photographs of six damaged pages from the gospel in 2001. Hedrick agreed with Robinson that the original Gospel of Judas was probably written in Greek in the second century AD. Scholars also agree that the scribal hand used in the Coptic translation would date that text to the fourth or fifth century.
Apparently, as with most of the gospels, a century or so after the death of the attributed author. A few of Paul's epistles excepted, of course.
