When you dig in a rustic with as a lot historical past as Britain, typically you discover one thing outstanding.

It is likely to be a gold necklace. It is likely to be the bones of a king.

Or, in a newer case, it is likely to be the marble head of a woman from the Roman period that disappeared in some unspecified time in the future within the final 250 years.

Sometimes, such a discover comes with a thriller: How the heck did the girl make her approach from Burghley House, a stately dwelling close to Peterborough, England, to a shallow grave 300 yards away?

“Burghley has thrown up all sorts of discoveries over the years,” Jon Culverhouse, the home’s curator, mentioned. “In cupboards, under stairs.”

A crew was constructing an auxiliary parking zone for the home final spring when the operator of an excavator, Greg Crawley, noticed the top in filth he had lifted. It was buried solely a foot or so beneath the floor.

Weeks later, the girl’s shoulders had been discovered, although they had been sculpted a lot later than the marble head. This form of Frankenstein statue was widespread within the 18th century, as including trendy shoulders made the traditional head extra fascinating to a possible purchaser.

The head has been dated to the primary or second century A.D., and it was very seemingly acquired by Brownlow Cecil, the ninth Earl of Exeter, on a visit to Italy within the 1760s. Such journeys, often known as the Grand Tour, had been “a rite of passage for a young aristocrat,” Mr. Culverhouse mentioned.

So how did the statue wind up beneath the earth? It’s laborious to know, partly as a result of the top doesn’t seem on any stock that researchers have been capable of finding.

But Mr. Culverhouse can provide some “informed speculation,” he mentioned. He thinks it was stolen, in all probability inside 100 years of its acquisition.

The head was discovered near a driveway resulting in the again door, which might have been the tradesman’s entrance, a probable escape route for thieves. But Mr. Culverhouse theorizes that the thieves obtained lower than a quarter-mile away with the top. “It’s heavy,” he mentioned. “I could well imagine them thinking, ‘We’ll put it here and come back later.’” Why they by no means got here again is unknown.

Researchers didn’t discover something about such a theft within the native newspaper archive, however “there probably wouldn’t be, because the owner would be very embarrassed,” Mr. Culverhouse mentioned.

The head may additionally have wound up buried there for another purpose. Did it tumble off a truck when being shipped someplace? Was it discarded by an art-loathing vulgarian? Answers stay elusive.

Beginning on Saturday, the reassembled statue can be on show at Burghley House, the place it can be part of many different artistic endeavors in addition to an journey playground as an attraction for guests. The home has been formally open to the general public since 1957. But as Mr. Culverhouse famous, for hundreds of years earlier than, “if you were well dressed and gave the housekeeper a shilling, she’d show you around.”

In the ebook “Pride and Prejudice,” the heroine, Elizabeth Bennet, passes by Pemberley, the house of the rich Mr. Darcy, and is fortunately proven round in simply such a approach. Burghley House appeared within the 2005 movie adaptation of the novel, although it stood in for Rosings Park, the house of Lady Catherine de Bourgh (performed by Judi Dench), not Pemberley.

“The house has always revealed secrets,” Mr. Culverhouse mentioned. “But nothing as romantic as this.”
