Religious Art in Museums

It troubles me that art has been "collected" and relocated to various places around the world, especially Egyptian artifacts, BUT ... Unless they are duplicated in something like fiberglass I would not have seen nor have appreciated them as much.

There are paintings like "Daniel in the Lion's Den" by Rubens which is located in the National Galley of Art in Washington D.C. I do not know its history, but I know my life would be diminished if it was located somewhere else. Framed it is (105 1/2 x 147 1/2 x 6 in.). It is enormous and absolutely captivating. I have visited it several times and have been overwhelmed at its power. Once I get there, I just do not want to leave the room.
