Piero della Francesca's "Senigallia Madonna"

The 24-by-21-inch work is a prime example of how a seemingly grim acknowledgment -- that the MFA had acquired works most likely looted from Italian soil -- has been turned into a bountiful cultural exchange. Back in 2006, under pressure and scrutiny from Italian investigators with photographic evidence that showed works looted sometime before they arrived in US museums, the MFA and the Metropolitan Museum of Art in New York struck deals to send objects back.

The loan of the Piero is part of a campaign by the Carabinieri, Italy's military police, to publicize their effort to recovery stolen artworks. So the MFA's Lee gallery will feature extensive wall labels detailing both the significance of the work as well as the tale of the theft.

Virginia Curry, a retired special agent with the Federal Bureau of Investigation, who has worked closely with the Carabinieri and also on the 1990 Gardner theft, said the MFA loan truly helps both parties. The MFA gets to show a priceless masterpiece. The Italians, sometimes criticized for reclaiming artworks on prime display in the United States and putting them in storage or in little-seen galleries, are able to share the country's culture.

“That’s really the purpose of it,” said Curry, who is based in Texas. “They’re showing that they’re willing to bring something back. That they’re not just going to demand the return of this material to be placed in a storehouse in Italy because they can’t display it as well as at the MFA or at the Metropolitan. They’re trying to show some responsibility and willingness to share their culture.”

The arrest of two men in Essex was a part of a joint police operation which saw a total of 17 men and 2 women arrested across the UK and Ireland, following a series of thefts at museums and auction houses in which ancient Chinese objects, Rhino horns and other works of art and antiques valued in excess of £20 million were stolen during the course of 2012. 

Police from 26 forces including An Garda Siochana in Ireland, the Police Service of Northern Ireland and members of the Serious and Organised Crime Agency (SOCA) raided houses and traveller camps in London, Essex, Cambridgeshire, Sussex, The West Midlands, Nottingham, Belfast, Cork and in Rathkeale near Limerick, the home of the Irish Traveller community. 

They are reported to have seized a large amount of unspecified property although it is not known whether this includes any of the rare Chinese jade carvings stolen from the Fitzwilliam Museum in Cambridge for which crime, four people were convicted earlier this year including a 15 year old boy. All were from the traveller community, members of whom have been responsible for a series of the major art and antique robberies committed in the UK in recent years. 

Not for the first time, the UK police were forced to create a cross border task force to investigate a series of crimes committed by travellers against public and private collections of art and antiques. The crimes themselves demonstrate how criminals follow trends in various markets, including the art market, and the explosion in value of Chinese artefacts following the re-emergence of the Chinese art market did not go unnoticed. Likewise, the high prices offered for Rhino horn in the Far East attracted the attention of criminals who realised that it was easier and safer to steal the horns from exhibits in museums rather than poach the horns from live animals in Africa. 

Travellers have been arrested in a number of European countries in connection with the theft of horns from museums, and Austria was recently seeking the extradition of one leading Traveller from Rathkeale. The scale of these crimes resulted in many institutions replacing the horns with replicas to discourage thefts, however in the case of the Norwich museum in Norfolk, the birthplace of Admiral Lord Nelson, when the burglars were unable to steal the Rhino horn they turned their attentions to other exhibits and stole some Nelsonian objects including a mourning ring worn by a member of Nelson's family following his death at the battle of Trafalgar in 1805. 

These crimes and how they and other art thefts are inspired by art market trends will be discussed in detail at the "Art Crime" Seminar to be held in Dallas Texas between the 14th - 18th October 2013 at the SMU Meadows School of the Arts at which I and former FBI Special Agent Virginia Curry will be talking.

It's estimated that there are now more than 10,000 metal detector users in England and Wales alone. They've been making an impact. In 2011, close to a million artifacts were found by hobbyists. Nearly 1,000 of those could be classed as treasure - precious metals discovered by metal detector users. 

No harm done? 

But not everyone is pleased. Archaeologist and illicit antiquities researcher at Cambridge University, Christos Tsirogiannis, is one of those concerned. He says the amateur archeologists are damaging important sites. 

"Every object has an amazing historical value, especially when it's found in its actual and original archeological context," Christos Tsirogiannis explains. "If something is extracted violently and by an uneducated, non-specialist person from its original context, this cannot be reconstructed."

"I'm sure that there are several people who are operating metal detectors and they do it just for excitement," he says. "But even in a legal way, the destruction that they generate is really big, and it is an unfortunate phenomenon that it is still legal."

That these works are sometimes fake or misleadingly labeled is no surprise to art experts and to foundations that monitor online art sales. But fraud has saturated certain sectors of the art market, experts say. 

“In every country that I visit, even Abu Dhabi, I’m approached by artists or estates who are desperate about the fake situation,” said Véronique Wiesinger, the director and senior curator of the Alberto and Annette Giacometti Foundation in Paris. “We counted the other day 2,005 fake Giacometti sculptures for sale” on just one Web site, she added. 

Many reputable online sellers, of course, deliver precisely what they advertise. “There is a lot of buying online, and most people are satisfied,” said Alan Bamberger, an art consultant and appraiser. 

Over the last few years the Internet has broadened the art market far beyond the exclusivity and opaque jargon of its moneyed enclaves and has helped turn the slogan “art for everyone” into reality. But it has also become a sort of bazaar, where shoppers of varying sophistication routinely encounter all degrees of flimflammery, from the schemes of experienced grifters to the innocent mistakes of the unwitting and naïve. A recent study by statisticians at George Washington University and the University of California, Irvine, estimated that as many as 91 percent of the drawings and small sculptures sold online through eBay as the work of the artist Henry Moore were fake.
