A treasonous Kings beheading, a guillotining during the French Revolution and seizure following a conviction for embezzlement have all led to some of historys greatest collections being sold and dispersed. In 2018, these illustrious collections and more have been reunited for some of the best shows of the year. Curators turned into sleuths as they tracked down treasures that once belonged to collectors of exquisite taste and unimaginable riches, but whose drive to hoard was not always unconnected to their eventual downfalls.

At Londons Royal Academy of Arts (RA) in January, more than 100 works were reunited for Charles I: King and Collector, in what was “one of the greatest feats of curation of modern times”, according to the art historian Bendor Grosvenor. The exhibition brought together highlights from Charles Is (1600-49) collection, perhaps the most important ever amassed by an individual in the UK. The show included works by Renaissance masters including Titian and Mantegna, as well as artists commissioned by Charles, most notably his court painter Anthony van Dyck. “The most important painting in the exhibition in our opinion, and the most complex loan to secure, was Van Dycks Charles I in the Hunting Field from the Louvre,” says the exhibitions co-curator Per Rumberg. The work returned to the UK for the first time since it was sold along with the rest of the collection in the so-called Commonwealth Sale following Charles Is beheading for treason.

Many of the works that remained in the UK after the sale were recovered by his son and heir Charles II (1630-85) following the Restoration in 1660. Charles IIs own collection—more ostentatious than his fathers—was the focus ofCharles II: Art and Power at the Queens Gallery in London earlier this year, which has now travelled to the Queens Gallery in Edinburgh (until 2 June 2019).

One of the works recovered by Charles II, which was in the RA show, was Orazio Gentileschis The Finding of Moses (around 1630-33). This huge painting would eventually end up in another notable collection belonging to Philippe II, Duke of Orléans (1674-1723), which was also reunited this year forThe Orléans Collection at the New Orleans Museum of Art (until 27 January 2019). The show of 36 works includes pieces by Old Masters such as Rubens and Rembrandt. But, according to the exhibitions curator Vanessa Schmid, some of the most satisfying loans secured were Alessandro Alloris Venus Disarming Cupid (around 1570), which is rarely lent partly because it is on wood panel and therefore “less likely to be approved for travel”, and Andrea del Sartos newly restored Leda and the Swan, “which has been in storage since 1865”.

The Orléans collection outlived Philippe II but was sold off in 1792 by his descendent Louis Philippe II, a year before he was guillotined during the French Revolution; the works were shortly thereafter dispersed in famous London sales. Collectors themselves can sometimes be as fascinating as the contents of their collection, and the Duke of Orléanss “reputation as a roué and for flamboyance, certainly piques interest”, Schmid says. Audiences are usually captivated by “the obsessive nature of true collectors”, she adds.

In the case of Giampietro Campana, “you cant separate the person and the collection,” says Laurent Haumesser, the co-curator ofA Dream of Italy: the Marquis Campanas Collection(until 18 February 2019) at the Musée du Louvre.

The 19th-century businessman amassed the largest private collection of his day, with 12,000 objects relating to Italian history, covering “almost everything from antiquity to the modern times”, Haumesser says. Campana was an ardent supporter of a unified Italy, so building his collection “was a political project, a way of showing what Italy could be”, Haumesser says.

However, after Campana was convicted of embezzlement during a high-profile trial in 1857, his vast collection was seized and sold by the Papal States. The bulk of it was bought by Napoleon III and shared between the Louvre and several regional museums, but other important artefacts ended up in major museums in St Petersburg and London.

One of the highlights of the Campana show is a giant bronze hand on loan from Romes Musei Capitolini, which was reunited with its missing index finger earlier this year. The digit had been discovered in the Louvre and then a 3D-printed resin copy was taken to Rome to “make sure it was the right one”, Haumesser says.

Another obsessive collector was the art historian and politician Horace Walpole (1717-97), who is the focus of a once-in-a-lifetime exhibition at Strawberry Hill, his former home west of London. In Lost Treasures of Strawberry Hill: Masterpieces from Horace Walpoles Collection (until 24 February 2019), more than 200 objects have been reunited and hung in their original locations thanks to detailed drawings of the house. Walpole wrote extensively about his collection as he “was haunted by the fear that one day the collection and house would be separated”, writes the curator Silvia Davoli in an essay for Apollo magazine. His fears were proved right as it was dispersed far and wide in a notorious 1842 London sale.

The breaking up of a collection is not always a bad thing, though. For example, in the case of the Duke of Orleanss collection, its sale and dispersal “unleashed a seismic change in patterns of viewership and in taste in England, ultimately catalysing new directions in 19th century British art”, Schmid says. The dispersals also mean that the works pass through other collections and travel around the world to be appreciated by different generations in different countries—one day being momentarily reunited for these once-in-a-lifetime shows.
