## Key points

- Twelve theft events sit in the graded provenance chains of ten records in this archive. In every one of them the owner column for the stolen years reads Unknown, or names the last lawful owner, or names the thief with the word theft beside it. A thief is never graded as an owner, because possession is not title.
- The objects came back five different ways, and the way decided what the owner paid. The Saliera and the Stone of Scone cost their owners nothing. The Breguet No. 160 came back through a lawyer for a sum reported at 35,000 to 40,000 dollars. UCLA paid a settlement to the woman holding its Stradivari. The Cantino planisphere was bought back on the open market and re-entered its own library as a gift.
- Two objects have not come back. Vermeer's The Concert has been missing since 18 March 1990 and title never moved, because the Gardner carried no theft cover and no insurer stepped in. Van Gogh's Vase with Viscaria has been stolen twice from the same Cairo museum and is missing now.
- The Hope Diamond is the case where the clock was the whole story. The first record of the recut stone in London is a memorandum dated 19 September 1812, two days after the twenty-year limitation on the 1792 theft from the Garde-Meuble had run out.
- A theft can be committed by the custodian. The hippocamp brooch of the Lydian Hoard was sold by the director of the museum holding it and replaced with a replica nine grams heavier. The theft was detected by weight, not by eye.

## A stolen object keeps its owner



## Five ways home, and what each one cost



## The recovery that cost nothing was the one the thief arranged



## Where a third party holds it, the owner pays to settle



## Where the object was sold on, the owner bought it back or lost it



## The clock is the whole story in one record



## The thief can be the custodian



## Two chains that end in an empty frame



## How to read a theft in a chain



A theft is the one event in a provenance that adds nothing to the chain and tests everything in it. Read the missing years for whose name is there, read the recovery for its grade, and read the mechanism for what the owner's title cost to enforce. Ten records here show that the price of getting an object back ran from nothing to a settlement to a full repurchase, and that two owners are still waiting. Record the theft as a span with a cause, keep the lawful owner underneath it, and never let a thief's possession harden into a link.

## Questions

**Does a thief ever appear as an owner in a provenance chain?**

Not in this archive. Across twelve theft events in ten records the owner column for the stolen years reads Unknown, or keeps the last lawful owner, or names the thief with the word theft beside it. A thief takes possession, not title, and the grading reflects that.

**How did the Cellini Saliera come back after the 2003 theft?**

The thief, Robert Mang, led the police on 21 January 2006 to a forest at Brand in Lower Austria where he had buried it in a lead-lined box, after an extortion attempt led to his identification. The Kunsthistorisches Museum put it back on display at the end of January 2006 and he was sentenced to five years.

**Why is the Hope Diamond's 1812 reappearance dated so precisely?**

The first record of the recut stone is John Francillon's memorandum in London describing a 45.5 carat blue diamond in Daniel Eliason's hands. The Smithsonian Libraries date it to 19 September 1812, two days after the twenty-year limitation on the September 1792 theft from the Garde-Meuble had expired. Whether the timing was calculated is not established.

**Did UCLA have to pay to get its Stradivari back?**

Yes. The violin was surrendered under a court order on 17 October 1994, and the settlement of 1 December 1995 gave UCLA sole possession in exchange for a payment to the woman who had received it in a divorce settlement, reported in the press at 11,500 dollars. UCLA's title was never in doubt.

**Which stolen objects in the archive have never been recovered?**

Vermeer's The Concert, taken from the Isabella Stewart Gardner Museum on 18 March 1990, and Van Gogh's Vase with Viscaria, taken from the Mohamed Mahmoud Khalil Museum in Cairo on 21 August 2010 after an earlier theft and recovery. Both are published here with title still in the museum and location unknown.

**How was the theft of the Lydian Hoard brooch detected?**

By weight. The replica put in its place at Usak weighs 23.5 grams against the original's 14.3. The museum's director admitted selling the genuine brooch in 2005 and was convicted in 2009; the original was recovered in Germany in November 2012.
