Bonham's and the Lydian silver kyathos: some unanswered questions

The decision by Bonham's to withdraw the Lydian silver kyathos from its London auction on Friday October 26, 2007 is welcome. It has come as a surprise as the kyathos was on display at the preview on the Thursday evening.

But there are a number of questions which remain.

a. Who took the decision to withdraw the kyathos from the sale? Was it Bonham's or the owner?
b. Are there documents that show the history of the piece prior to its surfacing at Sotheby's in the mid-1970s?
c. Is the kyathos being sent to Turkey? Or is it going back to its present proprietor?
d. Had the staff at Bonham's checked with the authorities in Turkey to ensure that this piece was not "stolen, illegally alienated, clandestinely excavated or illegally exported"? If not, why not?
e. What was the due diligence process undertaken by the staff at Bonham's?
f. Had Bonham's checked the kyathos against the Art Loss Register (ALR)? Was a certificate issued?
g. Why did the citation of a parallel from a well-known haul of Lydian silver plate not ring alarm bells with members of the antiquities department at Bonham's? Were they unaware of the significance?

Bonham's values its integrity. It has done the correct thing in this instance (although at what seems the eleventh hour). Will its senior management team now put in place a more robust process of checking antiquities prior to a sale?

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 …

The scale of the returns to Italy

I have been busy working on an overview, "Returning Archaeological Objects to Italy". The scale of the returns to Italy from North American collections and galleries is staggering: in excess of 350 objects. This is clearly the tip of the iceberg when it comes to the material that has surfaced on the market without a history that can be traced back to the period before 1970. 

I will provide more information in due course, but the researcher is a reminder that we need to take due diligence seriously when it comes to making acquisitions.

Stele returns to Greece

The Hellenic Ministry of Culture has announced (Saturday 8 September 2018) that a stele that had been due to be auctioned at Sotheby's in London in June 2017 has been returned to Greece (Friday 7 September 2018). The identification had been made by Cambridge-based forensic archaeologist Dr Christos Tsirogiannis.

It appeared that the stele had been supplied with a falsified history as its presence with Becchina until 1990 contradicted the published sale catalogue entry. It then moved into the hands of George Ortiz.

A year ago it was suggested that Sotheby's should contact the Greek authorities. Those negotiations appear to have concluded successfully.

The 4th century BC stele fragment, with the personal name, Hestiaios, will be displayed in the Epigraphic Museum in Athens. It appears to have come from a cemetery in Attica.
