High-Res Scan of Mona Lisa Reveals Its History 169

daevux writes "CNN is reporting that French engineer Pascal Cotte has discovered interesting details of the history of Da Vinci's Mona Lisa from a 240-megapixel scan of the artwork in various frequencies. Cotte surmises that the painted figure's eyebrows and eyelashes probably disappeared due to poor cleaning at some point in the past. He believes he can reconstruct the painting's original skin tones."

          I owned a stone house in Pittsburgh when I lived there. I thought I'd bought a gray stone house, but when it needed repointing and got spray-washed, I discovered I owned a yellow, red, tan, and generally pretty interestingly-colored stone house. The stones had just all turned gray because of the soot through the 20th century. So it doesn't always turn out like that.

No painting will never look exactly as it did when the painter's brush last touched it, but that moment is the moment the artist decided the painting was finished. If he wanted his painting to look so dark and drab and dreary, he would have used darker tones. Walk around your local art museum and you'll either come away wi

      There's something to be said for "oldness" under some circumstances, yes, but if anything, historical context would be re-gained.

      Personally, I'd like to see half this much attention being paid to Leonardo's painting of John the Baptist in the next room over, which is greatly superior in my opinion.

      (Yes, I mean the Leonardo one, not the "Bacchus/John the Baptist" one that can't be certainly ascribed to Leonardo, though that's also significantly better than the Mona Lisa.)

    would restoring the Mona Lisa to her original glory be in violation of the DMCA? Mother nature has specifically encoded the particles of the painting into their current state. Disassembling those particles or re-arranging them to unlock the original content seems to contravene explicit provisions of the DMCA.

    While the rest of the world may enjoy Leonardo's original work, here in the US we simply will not tolerate such abashed attacks on the copyrights of Leonardo. What do you mean copyright has expired? Ok, give us one more congressional session (and a couple pleasure boat cruises) and we will have that fixed.

    According to the article, there's a postulation that a curator or restorer might have accidentally cleaned off the eyebrows and eyelashes.

    FTA

    "And if you look closely at the eye of 'Mona Lisa' you can clearly see that the cracks around the eye have slightly disappeared, and that may be explained that one day a curator or restorer cleaned the eye, and cleaning the eye, removed, probably removed the eyelashes and eyebrow," he said.

    Why would a single pigment/color disappear?
    Weren't colors back then all made with the same base? In that case, why would only the eyebrows disappear and nothing else shows a smudge from whatever cleaning agent it was used? (if this is the case).

    Not to mention that I would have loved to be there for THAT occasion:

    Owner: "Can you get this thing cleaned up for me?"
    Curator: "Sure thing mister, I'm a professional."
    Owner: "It's priceless you know..."
    Curator: "I'll take good care of it."
    Curator starts the restoration from the eyes and accidentally wipes off eyebrows and eyelashes.
    Curator: "Fuck!"
    Curator: "Well... maybe if I get the eyes soaked in enough oil to not crack for 500 years, no one will notice."
    Owner gets back.
    Owner: "Hmm... look at them eyes! They're awesome!"
    Owner: "There's something different about her, is it her smile?"
    Curator: "I'm just a restorer, but yeah, er... she looks mysterious."
    Owner: "Nice eyes though!"

    So much speculation...

    150,000 dpi is a lot! As best I can tell the Mona Lisa is about 30 * 21 inches or 630 square inches which at 150,000 dpi would yield a 14.175 terapixel image, just 60,000 times the claimed 240 megapixels! 240 million pixels would be only 617 dpi!
