I have seen images and also seen one actual lead sheet. I have said nothing publicly yet, but privately I have said only that I think they are unlikely to be forgeries, but I did not use the word ‘genuine’ because it’s not clear what that would mean.
I do not know what these are are, or exactly how old. Like everyone else, I am waiting to see what further scientific tests show. But I have consulted a number of colleagues and so far none has been ready to declare them ‘forgeries’ either. Sensibly, they are going to wait and see. My position too is just that they should not yet be dismissed as ‘forgeries’. I think they are worth taking seriously for the time being.
I am not going to respond to every single inquiry about them, but I’m happy to tell you and indeed to encourage you to post this clarification as widely as you like!
Further, on the Biblical Studies list he writes
The provenance is known. I have consulted epigraphers, of course. The discovery is about 2 years old and the Easter timing is largely coincidental, forced by an unauthorized leak from a charlatan!
