As noted first on Paul Barford's blog, Portable Antiquity Collecting and Heritage Issues, the three items at Christie's identified last week by Dr. Christos Tsirogiannis as suspected looted objects have been withdrawn from this month's sale in New York City.

"Paul Barford notified me," Dr. Tsirogiannis wrote in an email to the ARCA blog, "I then verified it from Christie's website."

Dr. Tsirogiannis, a forensic archaeologist, identified images in the Christie's sales catalogue that matched images from the Symes-Michaelides and the Swingler archive (Professor David Gill provides more specific information here on his blog Looting Matters).

I asked Dr. Tsiogiannis who contacts the art market when researchers identify objects suspected to have been stolen? This is his response:
The auction houses, and the members of the international antiquities market in general, always have the opportunity to contact the Italian and Greek authorities directly, before the auctions. These authorities will check, for free, every single object for them. Instead, the members of the market not only are not contacting the authorities, but also complain publicly that they have no access to the archives. As long as the market does not cooperate with the relevant state authorities, those authorities will continue to intervene ex officio.

Opinion: More Questions Than Solutions from the Auction Houses

By Lynda Albertson

Following the successful identification and the subsequent withdrawal of the Sardinian idol, Dr. Christos Tsirogiannis, a forensic archaeologist and Research Assistant with the Trafficking Culture Project has forwarded ARCA four additional images of antiquities that match photos from the Symes-Michaelides archive.  

Tsirogiannis and Italian heritage professionals have been working diligently for years to make sense of a lengthy catalog photo and forensic documentation, that paint a vivid picture of the complexity of the network of dealers, middlemen, and tombaroli involved in the looting and smuggling of antiquities.

These four identified objects match auction items that are to be included in two December sales events; one held by Christie's New York scheduled for December 11, 2014 and another with Sotheby's New York to be held the following day.

Christies LOT 51: AN EGYPTIAN ALABASTER FIGURAL JUG, estimated at $150,000 -$250,000


 




The object appears in the same condition in the Symes-Michaelides archive. The dealers are not mentioned in the collecting history supplied by the auction house.









Christies LOT 95: AN ATTIC RED-FIGURED COLUMN KRATER, estimated at $60,000 -$90,000





The object is depicted in the same condition in the images that have been confiscated by the American authorities from the antiquities dealer David Swingler, among hundreds of antiquities which were repatriated to Italy after it was found that they were smuggled. Swingler's name is not included in the collecting history supplied by the auction house.


The object appears in the auction catalog with its surface cleaned, unlike its appearance in the Symes-Michaelides archive. The dealers are not mentioned in the collecting history supplied by auction house.






Sotheby's: LOT 6: An Egyptian Diorite Figure of a Priest of the Temple of Mut, late 25th/early 26th Dynasty, circa 670-610 B.C., estimated at $400,000 - 600,000






The object appears in the same condition in the Symes-Michaelides archive.  The dealers are not mentioned in the collecting history supplied by the auction house.








Note: These suspect objects have been brought to the attention of authorities in the United States, Italy and Egypt.

More than  four decades have passed since the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property. Despite greater public awareness of the problems posed by looting, suspect antiquities are still finding their way into auction houses through methods embedded within the licit antiquities trade.  By whitening a tainted object's illicit background through legitimate or contrived collection histories, laundered objects, be they from Italy, Egypt, Iraq or Syria, will continue to find their way into the glassy catalogs of licit objects being sold on the art market.

Unless tighter sanctions are imposed by governments or unless the art market itself voluntarily polices itself better, at the behest of culturally aware collectors or the general public, the problem will continue.  Predatory and subsistence looters will continue to supply the demand for materials needed and by proxy encourage the parasitical relationship between them, the middlemen suppliers and the auction houses.

Christie's Auction House Withdraws Sardinian Marble Female Idol from Upcoming New York City Sale

by Catherine Sezgin, ARCA Blog Editor and Lynda Albertson, ARCA CEO

Last week Dr. Christos Tsirogiannis pointed to a Sardinian marble female idol that Christie's planned to sell in New York City on December 11, 2014 -- an image of the idol had been identified previously in the Medici archive (see ARCA post here).  Further information on the background of this object's less than optimal collection history was later posted on Professor David Gill's blog Looting Matters and on Nord Wennerstrom's website Nord on Art

In protest of this sale Italian Camera Deputy Unidos Mauro Pili from the Regione of Sardinia wrote to Italy's ministro dei Beni culturali Dario Franceschini, Italy's Minister of Foreign Affairs, Paolo Esteri Gentiloni and to the US Ambassador of the United States to Italy, John Phillips demanding that immediate action be taken to stop the sale and to return the stolen goods to Sardinia.

Shortly thereafter, archaeologists in and around Italy formed a virtual protest group via social media provider Facebook also demanding the objects return.  This and other local interest action groups attracted more than 1000 followers. 

A few short minutes ago Deputy Unidos Mauro Pili released the following message. 
Poco fa la casa d'aste Christie's ha bloccato la vendita della Dea Madre ritirando dall'asta dell'11 dicembre prossimo il pezzo pregiatissimo della civiltà nuragica della Sardegna. Si tratta di un risultato importantissimo che segna un punto decisivo nella lotta ai furti d'opere archeologiche della Sardegna. Ora occorre andare sino in fondo per far restituire il maltolto alla Sardegna. Questo dimostra che la mobilitazione dell'opinione pubblica, dei media, e delle azioni parlamentari è utile ad accendere i riflettori su queste vergogne e bloccare queste vere proprie rapine al patrimonio della civiltà dei sardi.
The message indicates that Christie's has blocked the sale of the Mother Goddess, withdrawing it from its December 11th auction.  Deputy Pili further added that the blocking of this sale is a major achievement that marks a decisive point in the fight against theft of archaeological works of Sardinia.

A check of the Christie's New York auction side indicates the object has been removed from the online catalog for the upcoming sale proving that pressure at the state and local level can and does apply sufficient pressure to auction houses to lead them to do the right thing.

Dr. Christos Tsirogiannis identifies rare Sardinian idol to be auctioned at Christie's December 11 in New York City

Image of the Sardinian idol from the Medici
archive (provided by Dr. Tsirogiannis)
In the forthcoming December 11, 2014 auction at Christie's in New York, lot 85 'A SARDINIAN MARBLE FEMALE IDOL OZIERI CULTURE, CIRCA 2500-2000 B.C.', 'PROPERTY FROM THE MICHAEL AND JUDY STEINHARDT COLLECTION', is estimated at $800,000-1,200,000. Its provenance as listed on the sales documentation by Christie's states: 'with Harmon Fine Arts, New York. with The Merrin Gallery, New York, 1990 (Masterpieces of Cycladic Art, no. 27). Acquired by the current owner, 1997.'

"The object appears in the Medici archive, smashed in 6 pieces, missing the upper left part of its head," according to Dr. Christos Tsirogiannis, a Forensic Research Archaeologist who teaches ARCA's illicit trafficking course.  According to Tsirogiannis, "The Steinhardt collection has been previously connected with the acquisition of questionable antiquities."

The blog Chasing Aphrodite reported last November in "Steinhardt Redux: Feds Seize Fresco Looted from Italian World Heritage Site, Destined for New York Billionaire" that an earlier action had been taken against the antiquities collector, and stated: "The legal foundation for the case was created by Steinhardt himself twenty years ago with his failed effort -- fought all the way to the US Supreme Court -- to block the seizure of a golden libation bowl that was illegal exported from Sicily."

Dr. Tsirogiannis included an image from the Medici archive with the email announcing his discovery.

The Christie's catalogue can be downloaded here (first, press the button that says 'E-CATALOGUE'. The 150-page e-Catalogue advertises 192 Lots (or objects) to be sold at Rockefeller Plaza on the second Thursday of December. The objects (or 'properties' as described by Christie's on the page that lists the viewing dates prior to the sale) are from various collections. No further information is included about The Michael and Judy Steinhardt Collection in the e-catalogue. The Steinhardts also collect Judaica (Jewish art).

According to Christie's, this Sardinian marble female idol "comes from the Ozieri Culture of Sardinia, which takes its name from the town in the north of the island where the first excavations took place. Only very few such cruciform female idols survive."

Christie's and Bonhams withdraw two objects of antiquity linked to Medici and Becchina archives

Image appears to be draft of 1987 invoice
 on sale of antiquities
by Catherine Sezgin, ARCA Blog Editor-in-Chief

Both Christie's and Bonhams withdrew two objects -- a 2,000 year old Greek glass wine jug (called an oinochoe) and another ancient vessel (known as a pyxis)-- from their antiquities auctions this week that forensic archaeologist Dr. Christos Tsirogiannis linked to the Medici and Becchina archives.

In an email to ARCA's blog, Dr. Tsirogiannis wrote: "I am also sending you the documents related to the pyxis, which prove that Becchina sold the object to Ariadne Galleries, something that Bonhams failed to mention in the "provenance" section of their catalogue regarding this object." 

The documents, represented by the images here to the right in a bluish tinge and below in a pinkish tinge, appear to be the draft and final copy of an invoice. The pink image is a photograph of an invoice dated November 12, 1987 from U. R. Becchina to Mr. Torkom Demirjian at Ariadne Galleries Inc. at 970 Madison Avenue in New York City “(For definitive sale/no return) no return) for 23 items — 14 terracotta statuettes + 1 Pyxis, 2 Gnathian vessels, 2 Canosan Pyxides, and 4 Corinthian vessels — at a price in U.S. dollars of $21,800 plus a restoration fee of $3,700 for a total of $25,500. The invoice included: "GUARANTEE These items are of the period of the 6th to the 3rd cent. B.C. The authenticity is unconditionally guaranteed."

This is the image of the pink invoice
from Becchina to Ariadne Galleries
regarding the sale of antiquities
Peter Watson, co-author with Cecilia Todeschini of The Medici Conspiracy: The Illicit Journey of Looted Antiquities From Italy's Tomb Raiders to the World's Greatest Museums (Public Affairs, 2007), wrote in The Times ("Auction houses 'handling stolen goods'", April 2):
Christos Tsirogiannis, of the Division of Archaeology at Cambridge University, and formerly a member of the Greek Task Force that oversaw the return of smuggled objects, said that the auction houses should have realised that they were handling illegal objects. “They themselves do not release all the information they have about how these objects reach the market,” he said. “These objects have no real provenance.” 
The objects are believed to be part of hauls gathered during the 1980s and 1990s by Giacomo Medici and Gianfranco Becchina, two notorious Italian dealers. Both men have been convicted of trafficking in illicit antiquities. Medici’s archive was seized in 1995 in Geneva, and Becchina’s was seized in Basle in 2002. Between them, the men supplied thousands of illegally excavated and smuggled antiquities, many of which were dug up by mechanical digger, and sold at Sotheby’s throughout the 1980s and 1990s. Some of them were priceless and many still had soil on them. They passed in their thousands through London salesrooms until the traffic was exposed, partly by The Times in 1997. Sotheby’s was forced to discontinue its sales in London. 
[...] 
Mr Tsirogiannis, who has just been awarded his PhD for a thesis on the illicit international antiquities trade, has access to two Polaroid archives of the hauls that were seized by the Italian carabinieri in Switzerland. He noticed that the two objects coming up for sale at Bonhams and Christie’s were identical to two shown in the photographs of the seized archives, in one case dirty and broken before restoration. Invoices and sales receipts also appear to confirm that the objects are illicit. He said: “The object at Christie’s was sold at Sotheby’s in 1988, and that’s all — as anyone knows in this field, that almost certainly means it came from Medici. “The Bonhams object also first surfaced in 1987 and has no provenance outside the trade. There again, that should be a warning sign that the piece was illegally excavated and smuggled. Over the past few years, I have spotted dozens of objects like this being drip-fed on to the market, testing whether the Medici scandal has been forgotten. Each time, I have informed the Italian authorities, who tell me they always contact the auction houses, asking them to withdraw the pieces. They almost never do. I think they have only acted this time because The Times is watching. At this rate, London risks regaining its unenviable position as the home of the ‘dirty’ antiquities market.”
Watson reported that Christie's said that the company would contact Scotland Yard's Art & Antiquities Unit to investigate the piece and would return it to Italy if the object was the same as the one identified in the polaroid archive confiscated from Medici.

In an email to the ARCA blog, Dr. Tsirogiannis wrote:
A spokeswoman for Christie's said, regarding Christie's ownership of the oinochoe: 
The work you are referring to was sold through another auction house in 1988. It was then sold last year by Christie’s as part of the the Saeed Motamed collection. Christie’s became the owner after the sale of the work was then cancelled due to accidental damage sustained by the work during storage. 
My comment on this would be: Christie's should have been extra careful when they were exercising their 'due diligence' before the most recent sale, since they are the consigners in their own auction: as it turns out, this is a piece which comes originally from Medici. Christie's did not mention in the 'provenance' section of their catalogue which collection this object came from only last year, nor that the object was damaged during storage. All this exposes their practices even more.
Dr. Tsirogiannis wrote in an email to ARCA:
To echo Lord Renfrew in 2010, when four other antiquities I identified were withdrawn by Bonhams (http://www.theguardian.com/artanddesign/2010/apr/27/bonhams-stolen-roman-sculptures-auction), "London risks regaining its unenviable position as the home of the 'dirty' antiquities market".
Here's a link to the article in BBC News "'Looted' artifacts removed from auction" (2 April 2014).

Here's a link to Dr. Tsirogiannis' post "Auction houses should do more to rooted out looted antiquities" on the website for Apollo Magazine.

Dr. Christos Tsirogiannis matches two objects up for auction in London with objects identified in the Medici and Becchina archives

Medici oinochoe (Medici)
by Catherine Sezgin, ARCA Editor-in-Chief

University of Cambridge researcher Dr. Christos Tsirogiannis has reviewed the catalogues for three upcoming London auctions and identified two objects to photos in the archives of two art dealers, Giacomo Medici and Gianfranco Becchina, confiscated by Italian and Greek police who have used them to identify objects looted and smuggled from at least 1972 until 2006.

The three auctions of antiquities will be held at Bonhams on April 1; at Christie's on April 2; and again at Bonhams on April 3 

The first object is Lot 173 in Christie's Sale 1548 described as a Greek Core-Formed Glass Oinochoe from the Eastern Mediterranean, circa 2nd-1st century B.C., with an estimated bid at £4,000 - 6,000 (US $6,604 - $9,906). Christie's "Provenance" -- or what Dr. Tsirogiannis described in his email as the collecting history -- is described as:
"Anonymous sale; Sotheby's, London, 11 July 1988, lot 198".
"However, I identified the object from a Polaroid image from the Medici archive," Dr. Tsirogiannis wrote. "We know that Medici consigned hundreds of antiquities to Sotheby's (Watson & Todeschini, The Medici Conspiracy, 2007)."

The second object is Lot 22 in Bonhams April 3 sale (#21926) described as a Canosan polychrome painted lidded pottery pyxis, circa 3rd century B.C., with an estimated bid at £3,000 - 5,000 (US $5,000 - $8,300).  Bonhams' "Provenance" -- or collecting history -- of the oinochoe is:
"American private collection, New York, acquired from Ariadne Galleries, New York City in the late 1980s."
"However, I identified the pyxis in two Polaroid images from the Becchina archive (both attached, in the first the object is depicted broken and unclean, in the second the pyxis appears conserved and ready for sale)," Dr. Tsirogiannis wrote. "I have also found documents which prove that the depicted broken pyxis IS THE SAME as the one put on sale by Bonhams. Also, the same documents prove that Becchina sold the object to Ariadne Galleries, who were involved in other cases of "unprovenanced" antiquities (e.g., see Gill 2013 http://lootingmatters.blogspot.co.uk/2013/01/icklingham-bronzes-looking-back.html), Tsirogiannis 2013:10 http://art-crime.blogspot.co.uk/2013/07/the-journal-of-art-crime-spring-2013.html)."

"Why do Christie's and Bonhams still fail to supply the full and correct collecting history of the objects, especially when they advertise their due diligence before the auctions?" Dr. Tsirogiannis wrote. "Why are these objects depicted in the Medici and the Becchina archives?"

Christie's New York Auction of "Antiquities" withdraws "Symes Pan" from sale: Christos Tsirogiannis says that in due course more information will be found about The Medici Pan, the Hermes-Thoth, and the Symes Pan

"Hermes-Thoth" marble once passed
through the hands of Robin Symes
by Catherine Schofield Sezgin, ARCAblog Editor-in-Chief

As reported by Professor David Gill on his blog Looting Matters, Christie's New York auction house withdrew the "Symes Pan" identified by Cambridge's Dr. Christos Tsirogiannis from the Schinousa archive. Dr. Gill wrote in an email to the ARCAblog after conclusion of the three-hour "Antiquities" sale at Rockefeller Plaza today:
Buyers of antiquities are rightly concerned about buying objects that can be identified from the seized photographic archives such as the Medici Dossier and the Schinousa images that related to Robin Symes. Institutional reputation is also a factor and auction houses are wanting to distance themselves from any perception of endorsement of the illicit trade in antiquities.
The ARCAblog asked Dr. Tsirogiannis for his perspective on Sotheby's withdrawal of The Medici Pan; the sale of the Symes/Schinousa Hermes-Thoth marble by Sotheby's yesterday; and Christie's decision to not auction the Symes Pan):
The Medici Pan withdrawn by Sotheby's
The Medici Pan in Sotheby's seems to be a totally different case; it appears to lack any collecting history before 1975 and Sotheby's may have to explain when this antiquity passed through the hands of Medici and why Sotheby's did not refer to Medici as part of the collecting history of the object. I am sure that soon we will find out more interesting things about the case of The Medici Pan. 
Although the Hermes-Thoth head was sold with a collecting history before 1970, it is yet to be proved if it is still protected by any bilateral agreements between the US and other countries or breaks any national legislation. One question that Sotheby's may have to answer is when did the object pass through the hands of Robin Symes and Christos Michaelides.
Symes Pan withdrawn by Christie's
Regarding the Christie's Pan (lot 114), Christie's may have to answer why they withdrew the antiquity if it has a documented collecting history before 1970 (at least since 1968)? 
I am sure that in due course, more information will be found and will become available regarding these three cases.
The ARCAblog asked the opinion of Fabio Isman -- an Italian investigative journalist who has covered the illegal antiquities market for decades -- of how antiquities are sold in New York City with so little information about where they came from and how they got to the auction houses:
As usual, the auction houses don't quite care about the past. Important, for them, is only money. I think they are not very ethical. And, at the end, after Christos Tsirogiannis pointed out a few objects he recognized, they decided to withdraw two main objects: which was the minimum they could do.
Signore Isman, the author of "Pezzi di Medici e Symes: all'asta: fino a quando?" in the Italian Artemagazine, writes of "The Great Raid" in Italy since 1970 of the illegal excavation of 'at least one a half million artifacts' (Princeton University) that have been sold on the lucrative international market. Isman points out that of the 85 archaeological finds scheduled to be sold at Sotheby's in New York on December 12, that Christos Tsirogiannis, a Greek archaeologist working in England at Cambridge University, has identified two lots 'that are not new for anyone who has dealt with the Great Raid in Italy, from 1970 onwards.' 

Isman writes that Tsirogiannis identified a marble "Hermes-Thoth" from a photograph in the Schinousa archive, a group of photographs recovered by Greek police of objects Robin Symes and his partner Christos Michaelides sold through their gallery headquartered in London. Isman writes that according to Tsirogiannis Sotheby's acknowledges the connection to Symes but points to a private English collection as the source. Tsirogiannis also identified the Greek terracotta pan, withdrawn today from auction by Christies, from the Symes' photographic archives from the Greek island of Schiousa from where Symes and Michaelides conducted business away from the office. Christies listed the Merrin Gallery and a private New York collector as "provenance". Isman writes that Italian investigators have suspected the Merrin Gallery of conducting business with Gianfranco Becchina and Robert Hecht, art dealers allegedly transacting with Medici.  

Isman writes that the third object recognized by Tsirogiannis from one of the polaroids found in Medici's Geneva freeport warehouse is associated with the "Hydra Galerie", opened in Geneva by Medici, under a false name, in 1983.

At the end of this article, Fabio Isman laments the absence of Paolo Giorgio Ferri from the Cultural Heritage Ministry where he served two years before he returned to the Ministry of Justice -- in the past Ferri would have been the one protesting on behalf of the Italian government against the auction of these suspected artifacts.

Sotheby's sells Symes marble matched by Dr. Christos Tsirogiannis in the Schinousa archives for more than $4.6 million today; Sotheby's withdraws The Medici Pan; and Christie's in NY aims to sell Symes Pan tomorrow

Looting Matters: Hermes-Thoth
Image: Schinousa Archive
Today Sotheby's auction house in New York sold an ancient marble head for more than $4.6 million even after Dr. Christos Tsirogiannis pointed out that the piece, owned by Robin Symes, matched an image in the Schinousa archives. 

On December 5, Professor David Gills wrote on his blog "Looting Matters" under the post Symes and Hermes-Thoth about a 2,000 year old marble head for sale at a New York auction house today:
I am grateful to my Cambridge colleague Dr Christos Tsirogiannis for pointing out that the head of Hermes-Thoth due to be auctioned at Sotheby's New York next week had once passed through the hands of Robin Symes (December 12, 2013, lot 39). The estimate is $2.5-3.5 million.... Colour images of the head feature in the Schinousa archive where they were identified by Tsirogiannis.


In 2006, Peter Watson and Cecilia Todeschini published The Medici Conspiracy: the illicit journey of looted antiquities, from Italy's tomb raiders to the world's greatest museums, an expose about the network of tombaroli and art dealers who funneled looted antiquities into private and public collections from the 1960s through the 1990s. Peter Watson wrote Mr. Symes legal problems in "The fall of Robin Symes" in 2005. On Trafficking Culture, archaeologist Neil Brodie summarizes the illegal activities of Giacomo Medici, convicted in 2005 of receiving stolen goods, illegal export of goods, and conspiracy to traffic. Here's how Symes is believed to have been involved:
By the late 1980s, Medici had developed commercial relations with other major antiquities dealers including Robin Symes, Frieda Tchacos, Nikolas Koutoulakis, Robert Hecht, and the brothers Ali and Hischam Aboutaam (Watson and Todeschini 2007: 73-4). He was the ultimate source of artefacts that would subsequently be sold through dealers or auction houses to private collectors, including Lawrence and Barbara Fleischman, Maurice Tempelsman, Shelby White and Leon Levy, the Hunt brothers, George Ortiz, and José Luis Várez Fisa (Watson and Todeschini 2007: 112-34; Isman 2010), and to museums including the J. Paul Getty, the Metropolitan Museum of Art, the Cleveland Museum of Art, and the Boston Museum of Fine Arts.
Sotheby's Hermes-Thoth
Neil Brodie explained in September 2012:
Investigative reporter Nikolas Zirganos took a special interest in the activities of British antiquities dealer Robin Symes, and was present in April 2006 when Greek police raided a villa on the island of Schinoussa belonging to Symes and his deceased partner Christos Michaelides. Zirganos described how the villa on Schinoussa was used for what he described as the ‘preparation and closing of deals’ (Zirganos 2007: 318). The villa was in effect a social and commercial hub, where Symes and Michaelides would entertain archaeologists, museum curators, conservators and wealthy collectors to gossip about the market and what was available for purchase, and to arrange sales. Thus, it was possible for a customer to purchase an illicit artefact on Schinoussa without actually coming into contact with it. The artefact would be smuggled separately to Switzerland, where the customer could take possession of it.
Jason Felch, author of Chasing Aphrodite and an investigative journalist for The Los Angeles Times, wrote of Symes in January 2013:
Last year, the Getty quietly returned 150 marble fragments in the collection (88.AA.140 - 88.AA.144) to Italy after evidence emerged that they joined objects found in the same looted tombs of Ascoli Satriano that produced the Getty's Griffins and statue of Apollo, which were returned to Italy in 2007. The objects and fragments were acquired in the 1980s from London dealer Robin Symes.
Dr. Gill described the Schinousa archive last June on "Looting Matters":
This photographic archive records the material that passed through the hands of a London-based dealer. If material from this archive resurfaces on the market, it would be reasonable to see the full collecting history indicated. But such information would no doubt be provided by rigorous due diligence searches.
December 12, 20013, Sotheby's sold the late Hellenistic marble head of Hermes-Toth for $4,645,000 (Hammer's Price with Buyer's Premium)."

The Medici Pan withdrawn from sale at Sotheby's New York

Professor Gill also noted in "Looting Matters" that Dr. Christos Tsirogiannis identified "The Medici Pan" that was later withdrawn from the sale:
Sotheby's New York are due to auction a giallo antico marble bust of Pan next week (December 12, 2013, lot 51). The estimate is $10,000-$15,000. Dr Christos Tsirogiannis has pointed out to me that a polaroid image of the sculpture was found on the Geneva Freeport premises of Giacomo Medici.
The Symes Pan for sale Dec. 13 at Christie's Rockefeller Plaza

Again, on the blog "Looting Matters", Dr. Gill writes about another item for sale that caught the eye of forensic archaeologist Christos Tsirogiannis:
Tsirogiannis has now identified a terracotta Pan from the Schinousa archive that is due to be auctioned at Christie's Rockefeller Plaza (December 13, 2013, lot 114, estimate $8000 - $12000). Christie's have offered the following collecting history:
with Edward H. Merrin Gallery, New York, 1968.
Private Collection, New York, 1968-2011.
So when was the Pan in the possession of Robin Symes? What is the identity of the private collection? Is the collecting history presented by Christie's robust? What authenticated documentation was supplied to Christie's?
The Edward H. Merrin Gallery has been linked to the bronze Zeus returned to Italy, material in the collection of Dr Elie Borowski, as well as the marble Castor and Pollux on loan to New York's Metropolitan Museum of Art.
Artemagazine

The Italian Artemagazine  in "Pezzi di Medici e Symes all'asta: fino a quando?" (authored by Fabio Isman and his team) asks why illegally excavated antiquities from Italy are being offered for sale in New York City after Cambridge's Dr. Christos Tsirogiannis has identified the items to archives collected in police raids.
