Is This Rembrandt a Real One?

Roland Piquepaille writes "About a year ago, I told you about how computer scientists from Dartmouth college were investigating digital images. But they're also interested in old paintings authentication, as reports Wired Magazine in The Rembrandt Code. Mathematicians are using high-resolution digital cameras and computers to examine old paintings and evaluate their authenticity. Even the New York's Metropolitan Museum of Art is asking them to discover which of the 42 paintings it owns and that were once believed to be Rembrandts are really authentic. The Wired article is pretty entertaining, but this overview contains more details, pictures and references about this authentication process."

As long as the IO behaviour is what I wanted, that's all that matters!"

      Seriously, though... like it or not, the way that art appraisal work has little (nothing?) to do with talent of the artist, and everything to do with perceived value and context. After all, a sufficiently awesome printer could produce (in principle) copies of Rembrandts that most people would not be able to differentiate, but ultimately they would have little value. Similarly, artificial diamonds are just as good (or better) in terms of purity, hardness and optical properties as natural diamonds, but the natural diamonds are valued higher "just because."

      Even if no one can tell that it's a fake for many years, art critics want to know if it's real or not. Such knowledge can change the perceived value of the item, even if it doesn't change its physical appearance. Again, art value is NOT about how "nice" or "well done" a work is, but rather based on "how much are people willing to pay for it."

      And in a strange way, having some Rembrandts shown to be fake would actually INCREASE the value of all the other Rembrandts, since they would suddenly be perceived to be a more rare commodity than before. So in fact a Rembrandt collection could stand to have its calculated worth INCREASED if some of them were found to be fakes. (Obviously other Rembrandt collections would also increase in value, especially if it were found that they contained no fakes.)

      Lastly, let me mention that above and beyond the determination of the value of art, it's worthwhile from the perspective of art history to determine which ones are real and which are not. If a given conclusion about a time period is based upon a painting that turns out to be fake, well then we have to update the (art) history books.

      People value art for all sorts of reasons: they like the piece, or they collect the artist, or they're interested in history, or they want a status symbol, or they're so rich they don't know what to do with their money, etc..

      A painting - especially old painting - is different from other products in that it cannot be reproduced. It can be photographed, or made into prints, but there is only one original. It's the scarcity that drives up the price. Imagine how much a wealthy person would pay for the original Mona Lisa... and then compare that to to what they would pay for a copy - even an almost perfect one.

      Now Rembrandt is dead, so he cannot create any more paintings. The number of his artworks is finite. This is partly why the price of an artist's work goes up after he dies--the supply is set and can't be increased.

      So even if, theoretically, an identical copy could be made - people would not pay as much for it because it is not the original, and it is not connected to the artist. Imagine if you had something signed by your favorite celebrity. You would value it because that person actually signed it. You would not value a forgery by Joe from accounting, even if was perfect. And if you found out it was a fake, you would probably want your money back if you paid for it.

    Why yes, IAAAH (art historian). One of the posters asked whether a great painter could be emulated by another artists and still have the forgery (as it were) be considered as influential as an original.

    It's not just Rembrandt's personal technique. Rembrandt worked with multiple layers, allowing light to permeate the background and to reflect off of his subjects in the painting. This sensuous interest in the physical attributes of the body and its many colors, tonalities, and reflections created an impression of richness and fullness of form. The fact that his lines were more often suggested than revealed, as evidenced by his self-portrait in 1669, suggests the the bodies he paints are more naturalistic and complex than they let on.

    To feel for a Rembrandt painting is to watch the subjects evoke emotion and a secular pathos that is thick with a somewhat ungraceful suggestion of form, in which paintings would sometimes look unfinished, perhaps, or rather, lacking a rigid definition of form.

    You cannot just recreate this technique. It takes the painter who originally defined a style and technique to illustrate why the technique is being so revered. Many copied Warhol, but none are genuine Warhols. And Warhol merely did silk screens!

    Notice that it's the artist who is creative and unique that is revered, not the imposer or forgery.

  10. Two issues by Anonymous Coward · · Score: 5, Insightful

    There are two issues involved here. They are Legitimacy and Meaning, and they hinge on the question of whether we're considering a fake Rembrandt or a copied Rembrandt.

    A fake Rembrandt is a picture Rembrandt never painted but which was done in his style and with his techniques. A copied Rembrandt is a reproduction of a picture he did paint, where the original was lost before the advent of photography. There's no evidence to show that the copy isn't the original.

    It may not be terribly important to find out whether a given painting is an original or a copy. Either way, Rembrandt created the ideas in it. It's a reflection of his worldview, and its his statement as an artist. The value would probably plummet for emotional and romantic reasons. This is the issue of Legitimacy and you can feel however you like about that.

    A fake Rembrandt is a very different deal. Suppose that, five hundred years from now, film historians thought the movie Grease was actually made during the Fifties. Grease embodies the way that people felt about the Fifties and remebered it decades later. It is a depiction of the era, not a product of the era. Similarly, a fake Rembrandt is a depiction of Rembrandtness, not a production of Rembrandt.

    Determining the authenticity of a piece affects the interpretation both of all other pieces by that artist and our understanding of the time in which the faker lived.

    Alternately, suppose it was discovered that almost all of Hamlet was written by Shakespeare, but the famous To Be soliloquy was not. That speech would still be beautiful and much studied, but our understanding of the meaning of it would undoubtedly change.

    Fundamentally, geeks find it very difficult to understand that a given painting is not important. It is that paintings contribution to the world of artistic ideas which is important. When you go to see the Mona Lisa you won't melt or suddenly smell the sea air of Renaissance Italy. There's no magic there. If you don't understand Renaissance art or plan to study it, there's probably no point in seeing the painting. It's just a chick with a funny look on her face. There are paintings from the modern era, illustrations or comic book pages or whatever, which will genuinely speak much more directly to you. They're painted in the language of your time.

    The place where the two issues intersect is that an artist may well have put Meaning in some very tiny aspect of a painting which a copy cannot reproduce. Geeks are used to thinking that any data can be transcoded between forms. Music can be digitized to "beyond the range of human hearing," text can be typed, pictures can be scanned. The difference with a painting is that it is not actually a flat image on a piece of paper. A painting is a three dimensional sculpture, though a shallow one. The colour is only part of the visual information in a painting. Gloss, texture, thickness, translucency and a dozen other factors are also important.

    Again, the geek cry tends to be "but the human perceptual system just merges these together." That's sort of true, but if the viewer moves his head, everything changes.

    Because of this detail, it does matter whether a painting is the original or a copy. If it's a copy, we know some of the meaning has probably been lost. It may look like something Rembrandt could have painted, but it will only be what someone thought Rembrandt was saying, not what he actually said. It's a paraphrase.

    Conclusion: Authenticity matters if you care about art for reasons beyond the monetary.
