Not everyone gets to travel to Italy in their lives. A church here in Fort Wayne was selected to receive one of a limited number of "exact replicas" of Michelangelo's famous Pieta, depicting Mary holding the body of Jesus after the crucifixion. At first glance, I think this is a great opportunity for people who can't go to the Vatican to see one of history's greatest works of art, sort of. But on the other hand, I read that it's made from a block of marble, just like the original, and I really wonder how it can be an "exact replica." How does that work, exactly? If it's just a replica, carved by some really good sculptor, intended to match the original, it might be a fine work of art, but an "exact" replica? Or maybe it was produced mechanically, from, say, a 3-D laser scan of the original. I don't know. But I wonder if it's really quite the same thing as seeing the original.
