Have you spoken with the archaeologist? it is very interesting! what else did he tell you?
I also think that it is impossible to restore these monuments in this place. Because they can die. But if they build a new Parthenon - a copy of the old one in another place, I'll gladly see it.
In the museum on video, I saw very modern technologies for the restoration of Erechtheion sculptures. It was awesome...
I have discussed the idea of restoring the monuments in their original form on site. They were all strongly opposed. Almost a blasphemy. And I don't remember anyone giving any other reasoning other than "it's completely wrong".
Technically it can be done.
And why is it now being restored? The missing pieces of marble are replaced by a lighter one, this looks strange ...
I don't know ...
