1975 I met in Florence a Professor Carlo Pedretti, my former professor of art history.
And today a world renowned scholar over there, not of the Vinci Well, hey asked me if I could find some technological way to and for the five centuries old mystery related Teoh lost masterpiece by the another of ancient battles on getting which supposed to be located in the Holy 500 in Palazzo Vecchio in Florence.
Well, in the mid seventies, there were not great opportunities for her by engineer like me, especially nearly.
And so I decided, with some researchers from the United States and interest in Florence to start probing the murals decorated by Vasari on the long walls.
So they hold if I found that searching for the lost dramatic.
Unfortunately, at that time, we did not know that that was not exactly where we should be looking because we had to go much deeper in.
And so the research came to a halt, and it was only taking up in 2000 thanks to the interest and enthusiasm will begin his family.
Well, this time we focus on trying to reconstruct the way they hold.
If I fund there was before the remodeling and the so called Selig around that which was built in 14 94 and to find out the original doors windows.
And in order to do that, we first created three D model and then with thermography, we went on to discover hidden windows, this of the region, windows of the whole of the salad around it.
We also found out about the height of the ceiling, and we managed to reconstruct their for all the layout of this original whole.
The way was before the came bas rd and the structure the whole thing, including a staircase that was very important in order to precisely place the relevant Gary on a specific area of one of the tools.
Well, we also learned that Mazari, who was commissioned to remodel the hold if I funded between 15 60 15 74 by the Grand Duke, causing with the first of the medicine family.
We have at least two instances when he saved masterpieces specifically by placing a brick wall in front of it and leaving a small air gap.
The trinity of my stature, the Church of Santa Maria Novella in Florence, So we just said, Well, maybe that has something like that.
In the case of the this a great work about Orlando, since he was a great admire Lerner the Ventures.
So we built some a very sophisticated radar tennis just for probing both walls and set you for an air gun.
And we did find many on the right panel off the east wall in their gap.
Andi, that's where we believe the Bell and Gary, or at least the part that we know has been painted, which is called The Fight for the Standard, should be located well from there.
Unfortunately, in 2000 for the project came to a halt many political reasons.
So I decided to go back to my out, my mother and the interesting California's A Diego and I proposed to open up a research center for engineering sentences for culture heritage.
And in 2007 we create.
She's a three s research center for cultural heritage, specifically art, architecture and archaeology.
So students started to flow in and we started to build technologies because that's basically what we also need it in order to move forward and go and go and do fieldwork.
We came back in the hold if I funded in 2011 and this time with a great group of students and my colleague Professor Vaca Acosta, who is now the director tcisa three, and that we came back just since we knew already where to look for, to find out if there was still something left.
Well, we were confined, though limited.
I should say, for several reasons that it's not worth explaining to endoscopy only off the many other options we had and with a four millimeters camera attached to it.
We were successful in documenting and taking some fragments of ah, what it turns out to be a reddish color black color and that there is some beige fragments that later on we ran a much more sophisticated exams.
XRF X ray diffraction and the results are very positive, so far seems to indicate that indeed may have found some pigments.
And since we know for sure that no other artist has painted on that wall before, Vasari came in about 60 years later, well, those pigments are definitely related to mural painting and most likely to live well.
We are searching for the highest and highly praised the work of art ever achieved by mankind.
As a matter of fact, this is by far the most important commission Leonardo has ever head, and for doing this great masterpiece that he was named the number one artist You Florence.
At that time, I had also had the privilege since the last 37 years to work on several masterpieces, as you can see behind me.
But basically to do what Well process, for example, state of conservation.
See here face of the Madonna of the Chair that when just shining a UV light on it, you suddenly see another different lady age lady.
I should rather say there is a lot of vanished still sitting there, several re touches and some over cleaning it becomes very visible.
But but also technology has helped to write new pages of our history, or at least to abate pages about histories.
For example, the Lady with the Unicorn, another painted by Raphael.
Well, you see the unicorn.
A lot has been said and written about the unicorn, but should take an X I of the unicorn.
It becomes a papa Doc and no problem, but unfortunately continue with the scientific examination of this painting came out that Rafael did not paint the unicorn do not pay into the popular dog actually left the painting unfinished.
So all this writing about the exotic symbol of the Unicorn?
Unfortunately, it's not very reliable.
Well, also authenticity.
Just think for a moment.
If science really could move in the field of authenticity of works of art, there would be a culture evolution, to say the least.
But also, I would say, a market revolution at me and take this example autumn ourselves nice painting, which is still life at the Pitti Gallery and just have any for camera peering through.
And luckily for historians, it just was confirmed that there is a signature of the most serious even says when it was made and also the location.
So there was a good result sometime.
It's not that good.
And so again, authenticity and science could go together and change the way, not attributions being made.
But at least lay the ground for the aim or objective or sessions rather say, less subjective.
Attribution a city is done today, but I would say the discovery that really caught my imagination, my admiration is incredibly vivid.
Drawing under this they your brown layer of the adoration of the my job here, you see, is handmade setting X Y Z scanner with a neutral camera put on it and just peering through this brown layer of this masterpiece to reveal what could have bean underneath.
Well, this happens to be the most important painting we have in Italy by Leonardo da Vinci.
And look at the wonderful images of faces that nobody has seen for five centuries.
Look, this portrait their magnificent You see, you're not at work.
You see the generality of his creation right directly on the ground, layer off the panel and see this cool thing finding I should like to say a an elephant Because of this elephant over 70 new images came out never seen for centuries.
This was an epiphany.
We came to understand.
And to prove that the brown coating that we see today was not done by.
They're not DaVinci which left us only the other, drawing that for five centuries we were not able to see.
So thanks only to, uh, technology.
Well, the tablet Well, we thought, Well, if we have this pleasure, this privilege to see all this to find all these discoveries.
What about for everybody else?
So we thought of Ah, in augmented reality application using a tablet, let me show you just simulating what we could be doing any any of us could be doing in a museum environment.
So let's say that we go to a museum with a tablet, okay?
And we just aim the camera of the tablet to the painting that we're interested to see like this okay.
And that we just click on it reports.
And now let me turn to you.
So the moment the image or I should say the camera has locked in the painting.
Then the images we just saw off the other drawing are being loaded.
And so see, we can, as we said, we have zoom in, then we can scroll.
Okay, let's go and find the the elephant.
So all we need this one finger just wipe off and we see the elephants.
And then if we want, we can continue the scroll And to find out for example, on the staircase, the whole iconography is gonna be changed.
A lot of laymen reconstructing from the ruins of an old temple, a new temple and there a lot of figures showing up.
See, this is not just a curiosity, because it changes not just the iconography as you see it, but their chronology, the meaning off the painting.
And we believe this is a cool way, easy way that everybody could have access to, to become more the protagonist of your own discovery and not just be so passive about it as we are when we walk through.
Unless the rooms of museums thea The concept is the digital clinical chart, which is sounds very obvious if we were to talk about real patients.
But when we talk about works of art, unfortunately, never bean as an idea.
Well, we believe again that this should be the beginning, the very first step to do real conservation and allowing us to really explore and to understand everything related to the state of our conservation of the technique materials and also if, when and why we should restore and or rather to intervene on the environment surrounding the painting.
Well, our vision is to rediscover the spirit of the Renaissance, create in your discipline where engineering for culture headed is actually a symbol off blending Arkansans together.
We definitely need a new breed of engineers that will go out and do this kind of work and rediscover for us these values this culture values that we badly needed, especially today.
And if you want to summarize, they want just single word will.
This is what we're trying to do.
We try to give a future to our past in order to have a future as long as we live a life of curiosity and passion.
