As I suggested might be the case when news of the testing of the codices was announced, the lead is apparently ancient according to the results. I’m kind of amazed that the academic community isn’t saying “who cares?” — I guess they never read Wallace’s The Word. All this proves is that forgers used ancient material, not that the texts themselves are authentic, especially when there is abundant evidence to the contrary.
To the academic blogging community (I’d address the breathless media, but they haven’t listened from the beginning): Let’s use a little imagination. If you were going to fake these, wouldn’t you anticipate your work would be tested this way? I would, and I’d make sure to use real material before copying my content.
