Yesterday Bakur Abuladze, First Deputy Prosecutor General of Georgia announced the arrest of four individuals in the Eastern European country on charges of stealing rare 19th century books from national and university libraries in the Czech Republic, Germany, Estonia , France, Latvia, Lithuania, Poland, and Switzerland.    The arrests were born out of transnational crime group operation involving law enforcement officers from France, Germany, Lithuania and Switzerland, with coordination assistance via Europol and Eurojust.  Searching aparments and places of sale a large amount of cash and hundreds of books, many with their library watermarks evident,  were recovered, including a 19th-century French-language book allegedly stolen from the National Library of Paris

According to yesterday's announcements, between 2022 and 2023 this network of  accomplices visited libraries across Europe, gaining access to collections using fake IDs with fictitious names and surnames.  Having obtained access to collection material, they then exchanged rare book editions, primarily centring on Russian classics, in particular, books by Alexander Pushkin and Nikolai Gogol which they then substituted with makeshift counterfeits selling the books onward in Russia. 

Along with the financial motive for the crime,  journalists have speculated on a  political motive, where in the large-scale operation was incentivised by buyers seeking to return literary relics to Russia.  For now this theory is just that. 

In mid July, those following restitution news might have read about the United States and Italian authorities happily announcing the restitution of a stolen 15th-century letter written by Christopher Columbus.  Most of the many news articles which covered this particular restitution, were fairly pro forma.  They focused on the historic significance of this precious incunabulum, written by the controversial Italian explorer in 1493 upon returning from his first voyage to the so called "New World".  In his epistolary announcement, Columbus described his momentous journey to his royal patrons, King Ferdinand and Queen Isabella of Spain, who financed his expedition.

Portrait of Christopher Columbus  By Ridolfo Ghirlandaio

While the series of news articles discussed that the document had been stolen before 1988, from the Biblioteca Marciana in Venice, most were written in a perfunctory way, with many simply echoing the spartan details regarding the historical significance of this document, alongside the object's circulation as outlined in the US government's July 2023 announcement, ie., that the stolen document had been found in "the collection of a privately owned library located in the United States" after having been purchased via "a rare book dealer in the United States."

Why government press announcements on the restitution of historic artefacts can be rather "vanilla".  

Normally the investigative agency announcing a restitution begins by describing why the painting or artefact is significant, and when and/or where it has been stolen.  Press announcements then move on to state when, or sometimes how, the object in question has been identified, and then might, or might not, mention who the buyer or seller were.  Usually at the conclusion of these briefs, the announcement wraps things up by thanking key individual investigators and the agencies involved, wrapping things up by naming all of the ceremonial VIPs who would have been present during the handover ceremony.

But as participants of ARCA's PG Certification Program in Art Crime and Cultural Heritage Protection learn during their studies with us.  Sometimes these types of press statements leave us asking more questions than are answered.  One question being, why are these announcements intentionally vague. 

The writers of these briefings may choose to say less, as saying more might inadvertently impact other ongoing investigations. Other times, the agreed-upon press statement skims over the nominal information involving the handlers of the object for privacy considerations, or when the return is of a voluntary vs. criminal forfeiture.  

Names can also be left out when the collector or museum who previously held ownership of the artefact or artwork has consented to its seizure and civil forfeiture, but has insisted on confidentiality provisions as part of their agreed-upon settlement whereby they relinquish all rights and titles. In tandem, sometimes these settlements can carry stipulations which clearly state that by relinquishing said object, doing so in no way should be deemed as an admission of culpability, liability, or guilt. 

But what if you want to know more? And why we teach our researchers that OSINT gathering is a useful tradecraft, not reserved for the sneaky world of spies.  

One of the things ARCA strives to impart to its art crime trainees is the need to explore and research beyond what seems obvious.  To look beyond the low hanging fruit of a happy, but perfunctory, going home press release to what you might be able to find and interpret from unrelated sources.  This is useful for provenance researchers as knowing more about an object's handlers can (sometime) tell us more about other artworks or artefacts which should also be explored. 

To advance their provenance research skills, we teach our trainees how to conduct structured intelligence analysis, using a variety of techniques to efficiently gather and utilise the wealth of information readily accessible from disparate news sites, academic articles, blog posts, social media sites, search engine result pages (SERPs), and other public-facing digital assets.  We do so because true OSINT is more than just taking a stab at scrolling-through the first page of ranked Google hits. 

The European Commission defines open-source intelligence (OSINT) as the practice of collecting and analysing information gathered from open sources to produce actionable intelligence. 

At ARCA we provide our participants with opportunities to test their abilities in practical and advanced image and video analysis and verification, as well as fact-checking and analysis of information, disinformation, and misinformation.  These types of intelligence gathering can support, for example, national security, law enforcement investigations and even due diligence when vetting potential art and artefact purchases.  At its very core, OSINT investigations look for open (source) data which was created for one purpose but when combined with other data, shed's additional or unforeseen light on otherwise hidden topics. 

To illustrate how our researchers can glean more details on an object's circulation within the art, antiquities, and rare book market utilising only open source techniques, last month we had them start with the clues found in the July 18, 2023 U.S. Immigration and Customs Enforcement (ICE) announcement on the restitution of the  Columbus letter titled Epistola de insulis nuper inventis, Rome, Stephan Plannck, after 29 April 1493, Goff C-757 

I asked our researchers to explore a rudimentary hypothesis of whether this object's handlers might or might not be problematic art market actors and to back that up with their explorations.  I also asked them to try and explore who the collector might be who discreetly relinquished the Columbus document, and was he (or she) of the ilk known to satisfactorily vet potential acquisitions such as this historic document.

We started by documenting the July 2023 HSI-ICE announcement which featuring Special Agent Mark Olexa, who served as the lead case agent in this ten+ year investigation into the thefts of several historic incunabula stolen from Italy. 

His post appeared on Twitter on July 18th.

In this video we see footage of the what has come to be referred to as a Columbus Plannck I incunabulum, included the screen shot captured below.  Pay attention to the annotations marked in red, as these will provide confirmations that we will come back to later. 

From a November 14, 2019 Stipulation and Order IN RE: Columbus, Christopher, Epistola de Insulis Nuper Inventis, Case No. 20- ROME, Stephan Plannck after 29 April 1493, Goff C-757, we learn that: 

"In or around May 2003, INDIVIDUAL purchased the Biblioteca Nazionale Marciana's Columbus Letter-Plannck I from a rare book dealer in the United States for a sum of money."

A later United States Attorney's Office for the District of Delaware press release, dated January 22, 2020, states that this Plannck I edition of the Columbus letter has been valued in excess of $1,300,000, and is an exceptionally rare first edition that only mentions the King of Spain, while the second edition, commonly known as Plannck II, acknowledges both King Ferdinand and Queen Isabella.   This press release speaks to the good faith purchase of the document by the collector, stating:

"a collector acting in good faith unknowingly purchased the Biblioteca Nazionale Marciana’s Columbus Letter-Plannck I letter from a rare book dealer in the United States."

Also useful, Italian newspaper Corriere del Veneto geolocates the collector's home when describing where the Columbus document was discovered: 

"ritrovati i racconti di Critoforo Colombo rubati alla Marciana: erano a casa di un collezionista di Dallas"

 The key phrase being "in the house of a Dallas collector." 

Added to our earlier data of the document being found in "the collection of a privately owned library" we now can assume, if the Italian article is accurate, that the collector maintains a private library, in a home, located in the city of Dallas.

An excellent article by Nicholas Schmidle published on December 8, 2013 in The New Yorker gives us a pretty thorough rundown of Richard Lan, of Martayan Lan Inc., in New York City, who sold at least Christopher Columbus incunabulum in and around this same period. Talking about Lan's controversial relationship with notorious Italian book thief and forger Massimo Marino De Caro, writing 

"Despite these incidents, De Caro’s rise in the rare-book market continued largely unimpeded, as he obtained one remarkable book after another. Perhaps his most important client was Richard Lan. De Caro told me, “He was paying a high price for books, and he had the best customers in the world.” In 2004, Lan paid two hundred and forty thousand dollars for two of the Vatican books—first editions of Galileo’s “Discourses and Mathematical Demonstrations Concerning Two New Sciences” and “The Assayer”—and a 1611 copy of Johannes Kepler’s “Refraction.” Around this time, Lan also paid De Caro five hundred and eighty thousand dollars for a copy of the letter that Christopher Columbus sent to Ferdinand and Isabella in 1493, announcing the discovery of the New World. De Caro was beginning to think that Lan would buy anything from him."

In May 2012, De Caro, the former director of the Girolamini Library in Naples, was sentenced in Italy to 7 years imprisonment and a lifetime exclusion from public office following an expedited trial in Italy for the embezzlement of hundreds of stolen volumes from the Girolamini Library in Naples as well as thefts and forgeries impacting other libraries throughout Italy. 

Given that a Columbus incunabulum, stolen from the Vatican Library had already been identified as sold by De Caro to a New York dealer who turned out to be Richard Lan, then on to collector Robert David Parsons, an actuary from Atlanta, the anonymously described book seller involved, who is now deceased, becomes more interesting. 

But what about the Texas collector with a private library in him Dallas home?

Further exploration turns up several articles describing the expansive, and sometimes controversial, art and historical documents collection of Harlan Crow, a conservative billionaire, who recently gained unwanted attention for having been the secret benefactor of Supreme Court Justice Clarence Thomas.  Many articles refer to his ownership of an unique Christopher Columbus letter, but none of them, that we reviewed, provided imagery for comparison purposes.  

In one article, posted to the website InCollect discussing some of Crow's extraordinary pieces, we find another important clue, as the website describes the Texan's rare Columbus incunabulum as follows:

The document collection contains a first edition of the much sought-after “Columbus Letter.” Printed in Rome on April 29, 1493, this firsthand account of Columbus’s 1492 voyage of discovery was translated from his letter to the Spanish court. The Crow copy is the only version in private hands in North America; eleven other copies are located in institutional libraries in the U.S. such as the New York Public Library and twelve more are in European collections including the Vatican’s.

Given that the Harlan Crow Library copy is reported (and not proven) to be the sole extant Latin Stephan (Stephanus) Plannck (Planck) quarto written “To the Most Invincible King of the Spains” [Ad Inuictissimum Regem Hispaniarum] listed as being in private hands, our next step was to confirm through OSINT means, if it was  possible, that the one described and depicted in various restitution announcements could be the same document reported as being part of Crow's private collection in Dallas. 

Circling back to our screen grab from the HSI- ICE restitution tweet, we already had clear, high resolution images of the object which had been returned to the Italian authorities.  Now we just need to see if we could find an available image of the Columbus letter which was part of Crow's collection.  

Retrieving a 2019 web page, hosted by the Bullock Texas State History Museum, we were able to document, through images, exactly what Harlan Crow's Columbus incunabulum looks like.  In a comparison of the two, we can see that both the HSI-ICE image and the museum's photos of Crow's incunabulum both have matching traits, including a unique blue binding and slight page blemishes visible on two of the respective folio leaves.

Likewise a video presented of the object's return home published on Youtube also shows similarities in the fading of the ink's patterns.

Through this exercise, we can demonstrate that taking the time to scratch a bit beneath the surface of press announcements, and then systematically collecting analysing, and interpreting publicly available information from a wide array of sources, we can begin to further explore some interesting puzzle pieces.  Ones that might lead to an interesting thread or two worth pulling regarding how many other suspect manuscripts and rare books, stolen by De Caro, were purchased by Richard Lan, and in turn, did Lan sell other material to Harlan Crow, or others which can be traced back to thefts traceable to Massimo Messina De Caro's crime spree, or might still be in circulation in the rare text and manuscripts market in the United States.

OSINT Bibliography

The Biblioteca dei Girolamini in Naples

In a striking blow to the prosecution, former senator of Forza Italia, Marcello Dell'Utri has been acquitted by judges of the first criminal section of the Court of Naples of complicity in the embezzlement for the appropriation of thirteen volumes stolen from the Biblioteca dei Girolamini in Naples.  The theft was one of the most dramatic thefts ever to hit the rare-book world, with the prosecutor, Michele Fini, Antonella Serio and Ilaria Sasso del Verme having asked for seven years of imprisonment for the ex-politician. 

Law enforcement and Italian prosecutors began investigating the thefts at the historic library in 2012, following an email sent by philologist Filippomaria Pontani to art historian Tomaso Montanari after a disheartening visit to the shuttered library.  In that email, he recounted how the Girolamini, closed to the public for years, was in extreme disarray with numerous books and manuscripts missing. 

As news of the scandal spread, investigations into the situation ultimately led to the arrest of the director of the library, Massimo Marino De Caro, an international forger and swindler welcomed in the sacristies and antechambers of power, who appeared at the head of a network of collaborating actors who facilitated the laundering of stolen  historic books into the rare book market.  To remove proof of the books stolen origins, seals identifying the manuscripts as part of the Girolamini collection were removed or in some cases torn out altogether,  leaving telltale bite marks on the sacrificed pages. 

De Caro was ultimately sentenced to seven years in prison, the same penalty the Italian prosecutors had been asked for Dell’Utri.  De Caro was also convicted in additional judicial proceedings for the theft of a dozen volumes in the Abbey of Montecassino, the Observatory Ximeniano in Florence and from within the library collection of the Ministry of Agriculture.

With the help of this network of middlemen, book dealers and book conservators De Caro had been able to successfully steal thousands of books, some of which were acquired by, or gifted to, his Sicilian patron, Marcello Dell’Utri.   Yet, throughout the Girolamini investigation, the ex senator has proclaimed that he was unaware of the illegitimate origins of these historical volumes. In total, the former politician would ultimately surrender more than a dozen volumes traced to the Girolamini including:

➣De rebus gestis by Antonio Carafa

➣In hoc volumine haec... by Capitolinus et al., Aldina edition, printed in Venice in 1519 

➣Artificium perorandi by Giordano Bruno, 1612 "Clavis artis Iullianae" by Johann Heinrich Alsted, 1609 

➣De Principe by Leon Battista Alberti, 1520 

➣Panegyricus Philippo V Hispaniarum by Giovan Battista Vico, 1702 

➣Lu vivu mortu effettu di lu piccatu di la carni by Antonino Damiano, 1734 

➣La luce massonica. Visione di un confratello del p. Cristoforo by MGL of 1886 

➣L’asino d’oro by Lucio Apuleio filosofo platonico by Apuleius, 1665 

➣De optimo principe dialogus by Giovanni Bernardo Gualandi, c1561 

➣Trattato del governo de principi by Saint Thomas Aquinas, c 1577 

➣Petri Pauli Vergerij Iustinopolitani by Pietro Paolo Vergerio the Elder, 1526 

➣Leo Baptista De Albertis Florentius De Princepe by Leon Battista Alberti, 1520

➣and Utopia by Thomas Moore, 1518. The latter of which Dell'Utri did not return as he was unable to find it. 

But this case was not Dell'Utri's only brush with the law.  Apart from the bibliophile's passion for collecting rare books and incunabla, the ex politician and friend of Silvio Berlusconi has been found guilty of tax fraud, false accounting, and complicity in conspiracy with the Sicilian Mafia.   The last charge of which was upheld by the  Court of Cassation on 9 May 2014.  As part of that decision, and after exhausting appeals, the third criminal section of Palermo's Appellate Court declared Dell'Utri a fugitive and he was detained in Lebanon at a luxury hotel on an International Arrest Warrent a month later. 

Afterward, Dell'Utri was extradited back to Italy.  There he served 4 years in prison before being released to house arrest to serve out the remaining portion of his sentence, due to a substantial heart condition. 

In April 2018 Dell’Utri was again sentenced to 12 years in prison in the court of first instance, for undermining the state, via his involvement in the Trattativa Stato-Mafia, the negotiation between important Italian functionaries and Cosa Nostra members, that began after the period of the 1992 and 1993 terror attacks by the Sicilian Mafia.  His lawyers appealed that decision in March 2019 to the European Court of Human Rights in Strasbourg because he was allegedly illegally tried twice on the same facts and once acquitted. 

In closing this week's chapter on the library thefts, the judges of the first criminal section, chaired by Francesco Pellecchia, accepted the defence's arguements as made Dell’Utri's lawyers Claudio Botti and Francesco Centonze, showing that at least where books and manuscripts are concerned, Dell’Utri is still made of teflon.

On 29 January 2017 an organized crime group from Romania targeted and robbed over 200 rare books from a warehouse in Feltham, West London.  The collection consisted of 15th and 16th-century books and included works by well-known historical figures Galileo, Leonardo da Vinci, Isaac Newton, Dante Alighieri, and Nicolas Copernicus.  The most valuable of these was the 1566 copy of De Revolutionibus Orbium Coelestium by Nicolaus Copernicus but another lessor well known, and equally rare, texts, including a Muraqqa - album with Persian and Mughal miniatures were also taken in the heist. 

The books were owned by three collectors, two Italian and one based in Germany, and had been flown into the UK and stored in a climate-controlled warehouse while awaiting export to the United States for a scheduled book fair.  As the books were only intended to be at the warehouse for a short time period it is likely that the group involved in the theft had inside knowledge of the schedule of the books’ travel.  

When the theft was initially made public, many newspapers were more focused on the burglars' “mission-impossible" or "Ocean's Eleven-style" theatrics rather than on the cultural value of the rare books which were stolen, completely missing the value of Sir Isaac Newton’s 17th-century work “Mathematical Principles of Natural Philosophy” or fantastic etchings of the Spanish painter Francisco Goya.

To achieve their goal, the thieve's drilled through the building's skylight and rappelled down into the warehouse in order to avoid security measures.  Once inside they set about placing the rare books in large bags that could be hoisted back onto the roof, allowing the suspects to leave the way they came.  While it was expected that the books were either pre-sold to a collector or bound for the black market, nothing was seen of the books for nearly 3 years.   

The investigation of the theft was a multi-national collaboration involving the European Union Agency for Criminal Justice Cooperation and multiple law enforcement groups.   In a coordinated joint action day, in 2019 the Romanian, UK, and Italian authorities arrested 15 suspects, following 45 searches, in Romania and the UK, arresting a group of individuals believed to be responsible for a string of 12 highly-organised burglaries carried out across between December 2016 and April 2019.

Some of those taken into custody were linked to a number of prominent Romanian crime families who form part of the Clămparu crime group. This group has been known to be responsible for major heists, prostitution, and human trafficking offenses.   

According to released court records, forensic evidence and CCTV footage were both key to the investigation of the thefts and to the arrests of the co-conspirators.  Two days prior to the book theft CCTV footage captured images of three individuals involved in the heist:  Daniel David, Victor Opariuc, and Narcis Popescu, all three of whom are seen on footage arriving in the UK and driving to the warehouse in a blue Renault Megane. CCTV footage then shows David and Opariuc exit the van, leaving Popescu as a lookout while they cut through the warehouse's perimeter fencing.  

On the night of the theft itself, footage confirms that both Daniel David and Victor Opariuc returned, drilling through the skylight and entering the storage repository from above.  Once inside they are able to work undetected for five hours.  At 2:15 AM the pair exited back through the roof of the warehouse carrying large carryall bags, then loading up their cache into the Megane before driving away.  

To cover their tracks, the thieves quickly abandoned their get-away vehicle after wiping down the interior with cleaning products.  The stolen books were then transported to a house in Balham, rented temporarily to Narcis Popescu, where they remained for two days before being secreted out of the country.

Through examining cell phone records, the investigative teams were able to determine that the books were transported by a fourth accomplice, Marian Mamaliga to Romania, who left the UK through the Eurotunnel starting at Folkestone, Kent, and exited on the European mainland at Coquelles in Northern France. 

But even with that foresight to wipe down the car, forensic investigators were able to find a single hair on the drivers’ headrest which had escaped the burglar's clean-up.  This hair was later confirmed to be a match with Narcis Popescu.  DNA evidence inside the warehouse found on an escape ladder would also confirm the presence of Daniel David at the scene of the crime.   At other crime scenes, the members of the ring left drinks behind with traces of their DNA.

Perhaps the biggest break in the case though came from the evidence of a different theft conducted by the same group.  Some six months after the theft of the books, in July 2017, the group had moved on to target an electronics company, stealing some £150,000 worth of Lenovo laptops from another storage facility.   Similar to the book theft incident, the culprits of this later theft entered through the roof, this time using ladders both to scale and enter the building. This time transporting the hot merchandise proved their undoing.  Stopped by Romanian police Marian Mamalig could not provide proper proof of ownership for the laptops, and was arrested.   

Following resulting leads in 45 different locations in 3 separate countries, the books were recovered on Wednesday 16 September 16 2020 bringing the three-year joint investigation to an end.  Still wrapped in their original transport packaging, the rare books had been buried in a cement crawlspace under the floor tiles of a house in rural Romania in the historic region of Moldavia.  Once in law enforcement custody, the books were examined by conservators to assess for any moisture or mold damage and to carefully dehumidify the pages to prevent further damage. 

When speaking to the success of the investigation, Detective Inspector Andy Durham, from the Metropolitan Police's Specialist Crime South said: “These books are extremely valuable, but more importantly they are irreplaceable and are of great importance to international cultural heritage.”  Twelve of those involved in the thefts have pled guilty and received sentences  They are:  

• Marian Albu received 4 years imprisonment  
• Daniel David received 3 years 7 months imprisonment  
• Liviu Leahu received 3 years 8 month' imprisonment  
• Marian Mamaliga received 4 years and 1 month imprisonment.  
• Traian Mihulca received 4 years imprisonment  
• Victor Petrut Opariuc received 3 years 7 months imprisonment  
• Vasille Ionel Paragina received 3 years 8 months imprisonment  
• Paul Popeanu received 3 years 3 months imprisonment  
• Gavril Popinciuc received 5 years 8 months imprisonment  
• Narcis Popsecu received 4 years 2 months imprisonment  
• Ilie Ungureanu received 3 years 8 month' imprisonment  
• Christian Unrgureanu received 5 years and 1 month imprisonment   

A thirteenth is set to go to trial in March 2021.
