> A new wall doesn’t contain [traces of its original craftmanship]

I will add one quick thing: if that's true the initial wall is lost (obviously), old craftmanship is not lost. There is an organisation in France called "Les Compagnons du Devoir" [1] that does exactly this: (re)build things the way we built them centuries ago.

This organization has stonecutters and carpenters that could help a lot redo what was destroyed last night, with the know-how of the past.

So yes indeed, nothing is "lost", this is just another part of the cathedral's history.

I hope that they would not just try to re-create the past. That is impossible. I'd like to see the rebuild incorporate the absolute best of what we know from the past and modern techniques.
Re:The Notre Dame fire and the future of history by zaroth on Tuesday April 16, 2019 @11:53AM (#19674723)
“Modern techniques” are specifically calibrated and engineered not to last on the timescale of Notre Dame due to the costs involved.

Modern construction techniques are of very little use to repair a building which was itself built over the course of 150 years.

“Modern” gets you the $200mm staircase to nowhere at Hudson Yards in NY.

The question is for a building which actually struggled to raise the $7m used for the initial repair project, are people going to be patient enough to spend the $700m and 10/15/20 years to rebuild it with anything approaching the care, quality, and craftsmanship of the original?

The reconstruction should be the life’s work of a great master (or several great masters, when you consider the art and ornamentation that goes along with the architecture).

Do we still even do that sort of thing anymore?

Re:The Notre Dame fire and the future of history by rootusrootus on Tuesday April 16, 2019 @12:47PM (#19675192)
Modern techniques certainly can be used to build crap, but that is hardly a requirement. I bet they built plenty of crap a thousand years ago, too. I am very confident that we can build structures today that are better than anything ever built, when we choose to. Thing is, for most utility structures there is no particular benefit to building for that kind of longevity.

A good share of notable cathedrals have burned in recent history, and some of them have been rebuilt using modern techniques (e.g. Chartres, one of the most notable french cathedrals now has a metallic structure to bear its roof). These new techniques are both elegant and a better fit, as they protect the building from a (likely) fire in the future.

Arguing that cathedrals' wooden roofs are built to last while we don't know how to build longer-lasting work is a very curious take on the situation.

I'd wager yes, this probably woke people up that they've let their country's icon crumble, and money (and time) will now be no objects.

Something like 10 hours ago I was seeing a headline that €650 million had already been pledged for rebuilding from various private sources, so, yeah, I think it's reasonable to think that the money will be there.

Re:The Notre Dame fire and the future of history by zaroth on Tuesday April 16, 2019 @05:54PM (#19677697)
Too late to edit, but early estimates on the repair costs are actually $8 billion.

The roof that burned was called the Forest because it was made from 13,000 whole oak trees (the number varies depending on source) spanning 52 acres of forest.

Re:The Notre Dame fire and the future of history by gambiting on Wednesday April 17, 2019 @09:43AM (#19682453)
Then I'd be ok with replacing it with an identical "forest" made out of a modern material like carbon fibre, representing the original forest lost in the fire. Maybe we can even dedicate some area of land for oak growing so that in 300 years the trees will be ready to remake the original roof.
Re:The Notre Dame fire and the future of history by fennecfoxen on Tuesday April 16, 2019 @08:59PM (#19678735)
Apparently one of the major challenges in replacing the roof in the old style is that the typical oak used to construct it would have been ~300-400 years old and they just don't have a lot of those around anymore.
Re:The Notre Dame fire and the future of history by gbear605 on Tuesday April 16, 2019 @04:09PM (#19676848)
It’s already had 500 million euros dedicated to it, I believe.
Re:The Notre Dame fire and the future of history by theoh on Tuesday April 16, 2019 @01:59PM (#19675795)
There are agreed principles for the conservation of buildings. Three basic ones are:

a) Replace like with like (don't change materials or construction techniques)

b) Make any repair work obvious (don't try to pass new fabric off as original)

c) Repairs should be reversible.

It's a complicated field, but the general spirit is that when a building needs to be repaired, you try to make the new elements match as closely as possible to the way the structure was when it was first built. You don't say "we know better than the medieval masons, so we'll use reinforced concrete instead of stone" because that wouldn't be a restoration. It would turn the building into a hybrid of old and new technology, when what everyone wants is to experience the old way of building.

There's also an element of arrogance in trying to improve on medieval architecture—most people would agree that architecture, as an art, isn't something that progresses inexorably like science. The cathedrals are already as good as architecture gets. "Updating" a medieval structure to use the trendy structural technologies of the 21st century is a barbaric idea, because it is literally a case of destroying or interfering with an irreplaceable artefact.

Obviously, not every old structure has to be treated with kid gloves as a priceless artefact. But I hope you can see what I'm getting at when I say that "best practice" in building conservation means not acting as if you know better than the original builders. It's a case of respecting the original design and not messing with it for the sake of employing modern technology.

I don't think everyone agrees to this. At least, I don't. It's absurd to put a wooden roof back onto a structure seriously damaged by a roof fire. Whatever goes up there should be non-flammable. At minimum something that won't crash in the roof again in case there is a fire. Rebuilding it in the same fashion would be monumentally stupid.

Setting aside the safety issue, I go back and forth if it should be restored in exactly the same way. Notre Dame has been modified and improved over time and I don't necessarily think it needs to go back exactly the way it was. Like the glass pyramid in the Louvre perhaps modern materials can be an improvement.

Re:The Notre Dame fire and the future of history by rootusrootus on Tuesday April 16, 2019 @04:43PM (#19677109)
I think it would be a little insulting to try and replicate what was completely destroyed. Repairing something that has been lightly damaged or degraded over time is one thing. But when it's gone, it's gone, and the parts that are rebuilt should reflect our times, with a healthy nod of course to the existing structure that still remains. This is the next chapter in the building, something people will look back on a thousand years from now. We should make something we can be proud of.
Re:The Notre Dame fire and the future of history by theoh on Wednesday April 17, 2019 @10:14AM (#19682720)
A lot of aspects of Notre Dame date to the 19th C. Viollet-le-Duc made a lot of questionable improvements, including the addition of the flèche (spire).

That's part of the building's history now, for better or worse. I expect Viollet-le-Duc's work will be restored, even if some people think he was crass.

This whole issue isn't something that can be resolved easily. It's important not to look down on the activities of repair and maintenance. They might not be as glamorous as artistic creation, but obviously there's love, skill and creativity involved in repair as well. We need more of that.

A bad intervention by a currently successful artist or architect would be nothing to be proud of in future years. "Move fast and break things" is not appropriate in this situation. It's not as if a repair job involves pure boredom, imitation and humility—those craftsmen will be expressing themselves and their passion just fine.

The 19th C fixation on romantic originality, on the heroic artist? We don't need that. Not to be cynical about the state of architecture, but we can't match even Viollet-le-Duc's iffy work now. We need to shift into a different mode with more emphasis on preserving building skills and historical artefacts than on altering them to suit the whim of the people who happen to be alive now.

I think the Frauenkirche in Dresden is a counter example. That was reduced to a shattered hulk and rebuilt with as much of the original surviving stonework as possible.

Notably, there are some senses in which architecture can improve, with things like insulation, safety, or price.
Re:The Notre Dame fire and the future of history by theoh on Wednesday April 17, 2019 @05:28AM (#19681037)
Construction technology is not the same thing as architecture. Architecture as an art doesn't progress.

Music is the same, painting is the same. A piece of medieval music can be perfect on its own terms. It wouldn't make sense to say that electronic music is better because the tech is more advanced. Artistic value and technology are totally separate issues.

Re:The Notre Dame fire and the future of history by ionised on Wednesday April 17, 2019 @06:01AM (#19681182)
Technology has allowed people to create music in different and original ways, as well as proving entirely new instruments.

Painting materials have evolved and become cheaper, making art more accessible to the average person, expanding the artistic landscape.

These things have not stayed the same. It's odd that you think they have.

Re:The Notre Dame fire and the future of history by theoh on Wednesday April 17, 2019 @07:53AM (#19681704)
I didn't say that they stayed the same. The point is that you can't say objectively that these arts have progressed any more that you can say that human nature has changed for the better.

What I'm saying is not an unusual opinion. I mentioned electronic music, so it should have been obvious that I'm aware that "things have not stayed the same". But the point I'm trying to allude to is the fact that art is an expression of the human spirit, and because of that, it doesn't advance like science or technology.

Here's an example of someone writing in the Guardian:

"It was a year of revelations. The oldest portrait in the world – carved out of mammoth tusk 26,000 years ago in Moravia – had a long slender face, almond eyes and a rueful half-smile: just like a Modigliani. She came to the British Museum along with Ice Age drawings and sculptures so superb they have never been surpassed, proving once again that there is no progress – only change – in art."

From https://www.theguardian.com/culture/2013/dec/22/art-review-2...

Or, on a slightly different point: "It is obvious that art cannot teach anyone anything, since in four thousand years humanity has learnt nothing at all." (Tarkovsky)

Tarkovsky obviously isn't denying the growth of scientific knowledge. He just thinks there are aspects of human nature that only change slowly, if at all, and that those aspects are more significant than the accumulation of scientific knowledge and all the changes that brings about.

Re:The Notre Dame fire and the future of history by gbear605 on Wednesday April 17, 2019 @12:22PM (#19683952)
I guess it depends on the definition of progress. I see people able to do things previously impossible, which I say is progress, and you say that is not progress because the new things are not objectively better.
Re:The Notre Dame fire and the future of history by theoh on Wednesday April 17, 2019 @04:02PM (#19685969)
Acquiring the ability to wipe ourselves out with nuclear weapons is the classic example of this problem. The physicists weren't expecting that pushing the boundaries of what was technically possible would result in a very bad escalation of destructive capability, nuclear arsenals and the rest.

Progress in nuclear physics hasn't got a lot to do with progress in human politics and (dare I say it) justice/peace.

Construction technology is similar vis a vis architecture. Revit, 3D printing and advanced materials aren't an automatic ticket to making architectural work that's as good as or better than Angkor Wat. I mean, just what materials you build something out of, and what technologies you use, both obviously contribute to the particular artistic problem that the architect solves. But someone working with very limited technology can produce a fully developed artistic masterwork under those constraints. That's just something we know empirically from looking at the art of the past.

So this is more about never being complacent that what's being made today will match or surpass the artistic high points of the past. That's what the "no progress" concept means to me. There's a level playing field—none of us has any kind of technology that means we can unthinkingly produce work that compares well with renaissance masterpieces. The real picture is quite a bit more depressing that that...

I hope new artists get to contribute new takes on old ideas, instead of being reduced to highly talented imitation and clone manufacturers.
Re:The Notre Dame fire and the future of history by peterbraden on Wednesday April 17, 2019 @01:52AM (#19680085)
I hope they don't. Having seen the jarring modern takes on stained glass inserted anachronistically into old church settings, I have little faith that 'new takes' are able to blend into old surroundings.

There is beauty in reconstruction, and calling it 'fake' misses the point.
