The dating of an object by the study of radioactive decay of carbon-14 has had little application in the detection of art forgery because of the large quantities of material that must be destroyed. Thermoluminescent dating is based on the slight damage to all matter, including clays, by the faint nuclear radiation present in the earth. Magnetic dating of ceramic objects is based on the slow but perceptible shift of the earth’s magnetic field over the centuries.
Good solid provenance almost always increases the value and desirability of a work of art because, first and foremost, it authenticates the art. Good provenance also provides important information about and insight into a work of art's history. Unscrupulous sellers know the value of provenance and sometimes go to great lengths to manufacture or fabricate phony provenance for their art. The good news is that phony provenance is relatively easy to detect in most cases. The following guidelines will help protect you from buying art with fake or questionable provenance:
Copies, replicas, reproductions and pastiches are often legitimate works, and the distinction between a legitimate reproduction and deliberate forgery is blurred. For example, Guy Hain used original molds to reproduce several of Auguste Rodin's sculptures. However, when Hain then signed the reproductions with the name of Rodin's original foundry, the works became deliberate forgeries.
“It’s a useful resource for museums, auction houses, and dealers primarily that need to ply a particular artwork out of a collection,” says Brad Shar, whose New York–based firm Lowy works with both institutions and individual collectors to create reproductions. “The possibility of having an exact copy to fill a wall space is a powerful incentive a lot of the time.”
My predominant emotion while reading this book was irritation and I became much more interested in why it was irritating me so much than I was in the novel itself. I suppose principally because I thought it was going to be much more literary – a novel that creates the feeling that the characters are generating the plot rather than a novel whose plot creates the characters.
The Rothko even came with a romantic back story. As explained to the De Soles by Ann Freedman, then the highly regarded president of Knoedler & Co. — founded in 1846 and Manhattan’s oldest art gallery — it emerged from the collection of a mysterious Swiss heir. The man’s business-traveling father bought paintings directly from rising art stars of the 1950s. Freedman added that the piece, depicting Mark Rothko’s signature-style rectangles, had gone largely unseen by art-world cognoscenti.
In the geologic use of the term, provenance instead refers to the origin or source area of particles within a rock, most commonly in sedimentary rocks. It does not refer to the circumstances of the collection of the rock. The provenance of sandstone, in particular, can be evaluated by determining the proportion of quartz, feldspar, and lithic fragments (see diagram).
The 2,200 photographs by masters like Alfred Stieglitz, Edward Weston and Edward Steichen — more than could fit into an 18-wheeler — were paid for, court papers say, with some of the $78 million that the authorities say Mr. Rivkin got from defrauding oil companies like Shell, Exxon, and Mobil. Mr. Rivkin, who has not been charged with any crimes, was last thought to be in Spain and had arranged to have the photos shipped there.

James Martin’s expert report shows the signatures from four Knoedler paintings that were purported Jackson Pollocks. The top two signatures are quite similar. The bottom right signature shows signs that the name was first traced onto the canvas using a sharp tool, and is very similar to the signature on the bottom left, which is misspelled “Pollok.” Courtesy of James Martin.

Regardless of whether this provision ultimately is enacted, the underlying issue will persist.  This post discusses some of the general concerns that the art and antiquities world can be misused as a conduit for dirty money.  We then discuss the AML Standards for Art Market Operators proposed by the Basel Institute on Governance, and similar standards set forth by the Responsible Art Market, both of which attempt to set forth a framework for those in the business of trading art to mitigate their money laundering risks.


The fact that experts do not always agree on the authenticity of a particular item makes the matter of provenance more complex. Some artists have even accepted copies as their own work - Picasso once said that he "would sign a very good forgery".[citation needed] Camille Corot painted more than 700 works, but also signed copies made by others in his name, because he felt honored to be copied. Occasionally work that has previously been declared a forgery is later accepted as genuine; Vermeer's Young Woman Seated at the Virginals[21] had been regarded as a forgery from 1947 until March 2004, when it was finally declared genuine, although some experts still disagree.[22]

↑ Mario Clouds Not Bootleg V1.1 is a variation on Super Mario Clouds by Cory Arcangel. It was made available on the site NetVVorth as part of a collection of "forged" works by iconic digital artists. (Arcangel also offers instructions on his website that allow anyone to create a bootleg version of the piece.) It is still credited to "Cory Arcangel" in an attempt to highlight the ease of forging digital work. 


In recent weeks, the art world has been rocked by perhaps the biggest forgery scandal to hit the art world since Van Meegeren’s unmasking. The extent of the Old Master forgery ring is as of yet unknown, but Sotheby’s has already issued a refund to the buyer of a $10 million Frans Hals portrait, sold in 2011 in a private sale through London dealer Mark Weiss. James Martin’s Orion Analytical, a Williamstown, Massachusetts-based company which investigates artworks, found modern-day materials in the canvas, proving it to be a forgery.
Seed provenance refers to the specified area in which plants that produced seed are located or were derived. Local provenancing is a position maintained by ecologists that suggests that only seeds of local provenance should be planted in a particular area. However, this view depends on the adaptationist program – a view that populations are universally locally adapted.[63] It is maintained that local seed is best adapted to local conditions, and that outbreeding depression will be avoided. Evolutionary biologists suggest that strict adherence to provenance collecting is not a wise decision because:
Art frauds can also be difficult to prosecute because museum curators or collectors must admit to having been duped. Rarely do museums acknowledge that works of art they own may be inauthentic. When they do, it is often because they have no choice. The Boymans-van Beuningen Museum in Rotterdam, Netherlands, was forced to acknowledge that its “Vermeer” Supper at Emmaus was actually a forgery painted in the 1930s by van Meegeren, but the museum admitted that only after the forger himself, in the context of another investigation, had revealed his involvement. The work’s original collector, D.G. van Beuningen, continued to believe (despite van Meegeren’s claim) that the work was by Vermeer.
