'I've found a sword – and there's a hand on the end of it'

Some metal detectorists dream of making the find that changes history and 90-year-old Dave Derby has done just that – twice.
His first major discovery was of a grand Roman villa estate near Northampton, and that was followed by an Anglo-Saxon cemetery.
Archaeologist Stephen Young says Mr Derby "embodies the best of what it means to be a metal detectorist and an archaeological enthusiast".
Yet, for Mr Derby, from Kislingbury, near Northamptonshire, the greatest joy is finding ancient artefacts.

"You pick it up and think, 'What was the person like who owned it?'" he says.
His interest in metal detecting goes back to 1964, when he was helping his father in his garden.
"All of a sudden he bent down and picked something up - and it was a coin," recalls Mr Derby.
Experts from Northampton Museum explained it dated to the reign of George III (1760 to 1820).
"And I was hooked on what they were showing me, so I decided I was going to get a metal detector."
Over the decades, he made many finds, but the one that first attracted international attention was the 1996 discovery at Whitehall Farm of a Roman villa estate.

The extensive complex, dating to the early 3rd to late 4th Centuries, included two bath-houses, complete with tessellated mosaic floors, and two 2nd-Century round houses.
"I was detecting in a particular field and looking around, there was pottery lying around - then I started to find Roman coins," says Mr Derby.
"And the farmer had come along to see how I was doing and I said, 'You have a Roman site here.'"
They turned for advice to Mr Young, who had worked with Mr Derby since the mid-1980s.
"The site is a rare example of a late villa occupation remaining in use until the mid-5th Century, 50 years after the accepted termination of imperial Roman Britain," explains the former University of Northampton lecturer.

The discovery at Nether Heyford, near Northampton, developed into Clasp, a community archaeology project, which lasted until 2012, attracting students, volunteers and archaeologists from around the world.
Mr Derby's next massive discovery came when the same landowner offered him another field to survey.
"I went to this nice flat field and about 10 yards (9m) away from the hedge at the top, I got this fantastic signal," he says.
"And out came a lady's Saxon brooch, so I kept scratching around and I found a piece of metal which I thought could be part of a sword.
"I rang my son and said, 'You need to come – I've found a sword and there's a hand on the end of it!'"

By the time his son, Peter, turned up, the police had arrived to check the human remains were not the result of a recent murder.
The discovery in 2003 became known as the Anglo-Saxon warrior.
Further excavations in the area unearthed five more graves and then few years later, about 23 sets of remains were discovered.
Among them were the remains of what appear to be "feoderati", soldiers of continental origin invited to Britain by the Romans under treaty to provide military support, says Mr Young.
The burials revealed family groupings, with some of women's remains found to be of local origin.

Analysis suggested some possibly dated back to as far as 430AD - about the time the Roman empire was collapsing.
This made it "a seminal site of national importance for the post-Roman and early migration period of the 5th Century AD", says Mr Young.
Other finds included an early 6th-Century Mercian warrior burials and a 7th-Century mound burial of a man with a sword, whose rediscovery "was down to Dave Derby", he adds.
"I'm lucky to have worked with him and been able to integrate his talent and undoubted skills in enhancing our ability to understand the archaeological narrative," says Mr Young.
Mr Derby continues to love metal detecting, now accompanied by Peter, who says: "I feel like we're modern time travellers; we dig holes in the ground and uncover something that's not seen the light, sometimes for thousands of years."

All the gold and silver finds more than 300 years oldare reported to Northamptonshire's finds liaison officer, in line with the law.
One of Mr Derby's favourites is a 7th-Century gold and gemstone pendant, which was returned to the landowner and is now worn by his wife.
"I'd rather find artefacts - they belong to somebody and you think 'What were they doing there?'" he says.
"It's one of the most fantastic hobbies I've ever had."
