From BBC News – Jordan battles to regain ‘priceless’ Christian relics:

A group of 70 or so “books”, each with between five and 15 lead leaves bound by lead rings, was apparently discovered in a remote arid valley in northern Jordan somewhere between 2005 and 2007….

They could be the earliest Christian writing in existence, surviving almost 2,000 years in a Jordanian cave. They could, just possibly, change our understanding of how Jesus was crucified and resurrected, and how Christianity was born.
