Photographic Archives and Antiquities

The September 1995 raid on the Geneva Freeport premises of Giacomo Medici brought to light a major archive of some 4000 photographs. These images, some Polaroids, have been used by the Italian authorities to identify objects that have passed into public and private collections. By my estimate less than 1% of the items identified in the photographs have been returned to Italy.

The objects featured in the Geneva Polaroids are reported to include:


Other major sets of photographs have been seized from a Basel warehouse (approximately 10,000 images) and on the Greek island of Schinoussa. Research on this material will undoubtedly lead to further identifications. A related set of images show objects once handled by the Swiss-based conservator Fritz Bürki.

Other pieces identified by unspecified photographic archives:

Out of curiosity, why have the photographs not been released to the public, or even the Art Loss Register? Why not take a proactive approach as opposed to reactive each time one of the objects is set for auction? Is there fear that the objects will be driven "underground?" Whether or not that would happen is quite debatable.

You are assuming that (some of) the photographs are not on the ALR.

How hard would it be to compare photos of objects that come on sale to these photos using image-recognition software?

"Find photos like this" would at least be one way of looking for matches.

iPhoto can find lots of faces, and surely there are comparable things for objects. The auction houses would do this.

(I am assuming here that the auction houses are not simply ignoring what they know to be matches already.)

Image recognition software is here - and similar to the feature you mention on iPhoto for faces.
I hope that auction-houses are not ignoring identifications. We await a statement from the Art Loss Register. I have been in touch with two of their staff this week but you will have to be patient.
Best wishes

You are right David, Image Recognition software is there! It can very robustly recognize pictures of known paintings (stolen or not) on auction sites, or using a mobile phone or device in real antique stores. It is has been used by some police forces as well as insurance companies for 3-4 years now. For example see http://ltutech.com/clients/argos or or http://ltutech.com/en/clients/france-ocbc

The problem for police forces: stolen art teams are overall not very well funded, and can not always acquire the software or hardware they need. ALR will probably end up acquiring these technologies too.

All in all, it would be a great progress to generalize these tecnologies! It would make it so much harder to resell stolen art online...

Disclaimer: I am the CEO of www.ltutech.com, and we make image recognition tech bricks (basically, the algorithms) to build such software.

Codename: Ainsbrook

I have been watching (UK) Channel 4's Time Team this evening. The programme looked at an undisclosed field (under a potato crop) where a Viking burial had been found. The location in Yorkshire was so sensitive that it was given a codename: Ainsbrook. Here is the summary:
In late 2003 two metal detectorists were working in a field in Yorkshire. They found 'treasure' buried just beneath the surface – a collection of Viking material next to a body. Although they had been detecting on the site for a number of years, during which time they had made large numbers of finds, nothing they had uncovered previously compared with this. They decided to share their discovery with archaeologists.The programme explored the tension between metal-detectorists and the English Heritage sponsored archaeologists putting six trenches into the field based on a geo-physical survey. Finds made by the metal-detectorists did not easily map onto the archaeological features.

Part of the programme had an …

George Ortiz collection to be displayed in London

Christie's is due to display part of the former collection of the late George Ortiz in London in a non-selling show to mark the 25th anniversary of the exhibition at the Royal Academy. There is a statement on the Christie's website ("The Ortiz Collection — ‘proof that the past is in all of us’"). Max Bernheimer is quoted: ‘Ortiz was one of the pre-eminent collectors of his day’.

We recall the associations with Ortiz such as the Horiuchi sarcophagus, the Hestiaios stele fragment, the marble funerary lekythos, and the Castor and Pollux.

Bernheimer will, no doubt, wish to reflect on the Royal Academy exhibition by reading Christopher Chippindale and David W. J. Gill. 2000. "Material consequences of contemporary classical collecting." American Journal of Archaeology 104: 463-511 [JSTOR].

Bernheimer will probably want to re-read the two pieces by Peter Watson that appeared in The Times: , "Ancient art without a history" and "Fakes - the artifice b…

Adding to the history of an Attic black-figured amphora

The post-excavation histories of objects are important as we map the that cultural property passes through collections and the markets. This is clear for an Attic black-figured amphora, attributed to Group E, that is due to be auctioned at Christie's New York on October 31, 2018 (lot 31). It shows Herakles and the Nemean lion, and Theseus and the Minotaur.

The auction catalogue claims that it surfaced in the hands of John Hewett in London in 1970 (or earlier), then to a private collection in Europe, followed by a series of auctions:
