The Blenheim Sarcophagus: Roman Relic Discovered in a Tulip Planter

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

Concrete figures modelled on the Venus de Milo, terracotta pots resembling Grecian urns and herb borders fashioned in the style of 2,000-year-old bas-reliefs are all favoured by landscapers with refined tastes.

For one garden, however, the aspiration to classical grandeur turned out not to be make-believe.

The Blenheim Sarcophagus in a palace garden

Within the grounds of England’s 18th-century Blenheim Palace, a marble-faced tub used as a planter for tulips proved to be much older than it initially appeared.

In 2017, palace staff and conservators announced that its marble facing formed part of an authentic ancient Roman sarcophagus, dating from about the third century CE.

For almost two centuries, the carved marble slab had functioned as garden decoration: first as a water feature, then as a planter. Despite that unassuming purpose, it had originally belonged to an ornate stone coffin made for a wealthy Roman during the height of the empire.

It has since been meticulously conserved and moved indoors for public display.

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

It may sound like the story of a little-known rarity at last receiving its deserved recognition. Yet the history of this particular artefact is considerably more unusual.

The object subsequently known as the Blenheim Sarcophagus was not unknown, nor was it obscure.

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

Its bas-relief shows an intoxicated Dionysus celebrating alongside Hercules and Ariadne, with lion heads on 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

Documented references to the sarcophagus go back for centuries.

Before 1530, the Italian artist Battista Franco Veneziano made a sketch of its scene; that drawing is now held by the Städel Museum in Germany.

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

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

In 2010, an anonymous visitor uploaded a photograph of the object in the Blenheim grounds to TripAdvisor, captioning it, "a flower bed that looks like a Roman lenos sarcophagus". A lenos sarcophagus has the form of a bathtub.

The piece appears to have been concealed in plain sight. Yet media reports from 2017 said that Blenheim Palace did not know its provenance until 2016, when an antiquities specialist visiting for another purpose encouraged staff to investigate it.

The marble slab, the sarcophagus’s sole surviving section, had been fixed to a tub for use as a garden feature. After it was removed, it measured around 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 the Blenheim Sarcophagus went unnoticed

How, then, did it escape recognition for so long while so many visitors passed it regularly?

Many people probably presumed it was a replica, like the classical reproductions found across numerous gardens and estates.

According to Christopher Dickenson, an ancient historian and archaeologist at the University of Oxford in the UK, others may simply have assumed, as he had, that Blenheim staff knew exactly 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."

Visitors to Blenheim can now view the artefact in a more suitable environment and recognise it for what it is: a survivor of ancient funerary customs, preserved through the centuries rather than merely used as a container for tulips.

"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 Blenheim Palace House Manager Kate Ballenger.

One substantial mystery nevertheless remains.

The object is known only to have entered the possession of the 5th Duke of Marlborough, then owner of the palace, at some point during the 19th century.

Exactly when he acquired it, and how, may never be known.
