I'll be very interested to see what they find.
From the video:
"The modest tomb has never been photographed, and no drawings exist. This is the first time anyone alive today has seen the Holy Bed. Conservationists were surprised to find something their instruments didn't detect -- A layer of debris underneath the marble cover. They will analyze the debris to learn more about the ancient resting place."
Article:
"The exposure of the burial bed is giving researchers an unprecedented opportunity to study the original surface of what is considered the most sacred site in Christianity. An analysis of the original rock may enable them to better understand not only the original form of the tomb chamber, but also how it evolved as the focal point of veneration since it was first identified by Helena, mother of the Roman emperor Constantine, in A.D. 326.
"We are at the critical moment for rehabilitating the Edicule," Moropoulou said. "The techniques we're using to document this unique monument will enable the world to study our findings as if they themselves were in the tomb of Christ."
It would be something if they could reconstruct the tomb and chamber.
The one I was familiar with looks like this, but it's an example:
This is how the ediface looked before restoration:
So how did they know they found Christ's tomb?
"When the pagan shrines were cleared away in the early fourth century few expected to find any trace of the original tomb. To their surprise the tombs shown below where found and also the one identified as being used by Jesus. How was it known? It was the only one found there with a rolling stone! Fragments of the rolling stone are still in the possession of the church (fragments because pilgrims kept breaking of pieces for relics and souvenirs in ancient times).
Mark 16:2-4 Very early on the first day of the week, just after sunrise, they were on their way to the tomb 3 and they asked each other, "Who will roll the stone away from the entrance of the tomb?" 4 But when they looked up, they saw that the stone, which was very large, had been rolled away.
Rolling stone tombs were in fact quite rare during that period. Out of all the period tombs excavated in Jerusalem and area only a handful had a rolling stone, the remainder having rectangular stones that were merely pushed into place. Interestingly all the tombs found with a rolling stone were those of rich or prominent individuals/families. Perhaps this was due to the fact it would have cost more to have a stone shaped to round. Jesus, of course, was buried in one such tomb..."
