Professor Evans has a rare chance to view the Codex Bezae housed at the Cambridge University Library. Insider details: Agraphon means "not written " (in the New Testament Gospels). Agrapha is the plural. In this case, the Bezae agraphon is written in a Gospel, but it is not really part of the Gospel story, so is regarded as an agraphon. This particular agraphon in Bezae appears in a Codex of Gospels, whereas normally they are found as quotations in the writings of 2nd and 3rd century church fathers.
