On a serious note, do you know if these frescos will be left in place or removed to the museums for better curation?
I’ve only gotten to Pompeii once, seven or eight years ago, and of course most of the surviving decorative arts had been removed. There were just a few scattered examples remaining. We got the lecture about the preservation issues involved, but time, technologies, and standards of curation march on. Protection against direct sunlight and airborne pollutants would be issues, but for all I know, there might be technical solutions available now.
It would of course be nice to see as much as possible onsite, but in addition, museums end up putting a lot of their holdings into storage. Since cost is no object when it comes to archaeological sites (/s), I’d be all in favor of preservation in place if it’s technically feasible.
I don’t. In the past some have been removed for conservation and then returned to the original spot. Others were moved permanently to museums. Building a new roof was the approach for the House of the Vettei, although the original was over a second storey which is lost.
