I watched all but 10min. of the first video and found it very interesting and informative. The fact that there was that much restoration of antique pieces was enlightening.
You see, I have always wondered how magnificent sculptures just happened to be found buried in the ground. Why were they abandoned (unless buried by lava of course) and not ruined by earthquakes and plunder. I guess I'm naive. ha But now I understand. These pieces in the collections were displayed as art, not antiquities.
But did I also hear that many of the sculptures were restored in ancient times as well?
