Blenheim Sarcophagus: The Roman Relic Hidden as a Tulip Planter

A walk through almost any garden centre is likely to reveal decorative pieces drawing on the classical world.

A concrete statue modelled on the Venus de Milo, terracotta pots fashioned like Greek urns and herb borders arranged in the style of a 2,000-year-old bas-relief are all favoured by gardeners with refined tastes.

For one garden, however, the aspiration to classical elegance proved not to be an imitation after all.

The Blenheim Sarcophagus in the palace grounds

At England's 18th-century Blenheim Palace, a marble-faced container used to grow tulips proved to be much older than it initially appeared.

In 2017, palace staff and conservators announced that its marble facing belonged to an authentic ancient Roman sarcophagus dating from around the third century CE.

For almost two centuries, the carved marble section had functioned as a garden decoration: initially a water feature, then a planter. Behind that modest use lay part of an elaborate stone coffin made for a wealthy Roman at the height of the empire.

It has since been sensitively restored and moved indoors for display.

"The piece is actually in remarkable condition considering it has withstood seemingly aggressive environments; particularly that of a fountain receptacle," said Nicholas Banfield, a conservator at Cliveden Conservation who led the restoration.

"Following an initial in-situ inspection, we were able to unbolt it from the lead cistern to which it was attached and take it back to our workshops for full cleaning, repair, and stabilization."

This may sound like the story of an unusual, little-known object finally gaining its rightful recognition. The history of this particular artefact, though, is considerably more unusual.

The Blenheim Sarcophagus, as it became known, was neither unrecognised nor obscure.

Zahra Newby, a classicist at the University of Warwick in the UK, examined the artefact in a book chapter about portraiture on Roman sarcophagi.

Its bas-relief shows an intoxicated Dionysus revelling with Hercules and Ariadne, with lion heads at either side.

"An example in Blenheim shows the drunken Dionysus standing in the center of the sarcophagus…" she wrote.

Centuries of references to the Roman artefact

References to the sarcophagus can, in fact, be traced back for centuries.

Before 1530, Italian artist Battista Franco Veneziano drew the scene; that sketch is now held by the Städel Museum in Germany.

The Metropolitan Museum of Art in the US also owns a 16th-century drawing of the sarcophagus, credited to an unidentified artist.

Adolf Michaelis included it in his 1882 book Ancient Marbles in Great Britain.

In 2010, an unnamed visitor uploaded an image of the object in the Blenheim grounds to TripAdvisor, captioning it, "a flower bed that looks like a Roman lenos sarcophagus". A lenos sarcophagus is shaped like a bathtub.

The object appears to have been concealed in plain sight. Yet media reports in 2017 said that Blenheim Palace did not know its provenance until an antiquities specialist, visiting in 2016 for unrelated reasons, encouraged staff to look into it.

The marble panel, the sarcophagus's sole surviving section, had been fixed to a tub for use as a garden feature. After it was detached, it measured about 2 metres long and weighed nearly 400 kilograms.

Experts reportedly valued it at £300,000 (US$400,000 at current exchange rates at time of writing).

Why, then, had it gone unremarked for so long while so many visitors passed it regularly?

Many people probably believed it was a replica, like the numerous classical reproductions found in gardens and country estates.

But Christopher Dickenson, an ancient historian and archaeologist at the University of Oxford in the UK, suggested that many visitors probably assumed, as he had, that Blenheim staff already understood what they possessed.

"The truth must surely be that everybody who saw it and recognized it simply assumed that the people at Blenheim were fully aware what it was," Dickenson wrote. "That was certainly my assumption."

A restored relic, with its origins still unknown

Visitors to Blenheim can now view the artefact in a setting better suited to it, and recognise its true nature: not a container for tulips, but a survivor of ancient funerary customs that has endured for centuries.

"Now it is in a consistent indoor climate away from the natural elements, we are hoping it will remain in good condition and survive for many more centuries to come," said Kate Ballenger, House Manager at Blenheim Palace.

One major question nevertheless remains unanswered.

The only known detail is that the object came into the possession of the 5th Duke of Marlborough, the palace's owner at the time, at some point during the 19th century.

When he acquired it, and how, may never be known.
