It's frustrating that so often important archeological remains which pertain to religious issues fall into the hands of the Vatican. The same thing happened with the Dead Sea scrolls. By the time these things become available to the public, you have no way of knowing what they may have weeded out or destroyed. They've been doing this since they got away with burning down the library of Alexandria. For all their posing, they do indeed see knowledge as the enemy of religion - and with good reason.
