A significant discovery…

One evening in October last year I’d just got home from work when I received a call from Trevor Rogers, a metal detectorist I knew from my time as Portable Antiquities Scheme Finds Liaison Officer (FLO) for Kent. Trevor said he had made a ‘significant discovery’.

In my line of work getting such a call is not that unusual. But Trevor went on to say that he had found what he believed to be a ‘Celtic bronze helmet’. That got my attention.

I knew of no such helmets from Kent; the ‘Deal warrior’ had a bronze head-dress, but that was not a helmet as such. Even for Britain as a whole, I knew such a find would be incredibly rare. But Trevor was very specific; he said it appeared to be a ‘Mannheim’ type helmet. I knew that Trevor was an experienced detectorist and he sounded like he knew what he was talking about, so I arranged to visit him first thing next morning to have a look for myself.

As I drove to Trevor’s place the next day, I really didn’t know what to expect. There was either going to be disappointment for both of us, with me having to break it to Trevor that he was mistaken and had found something actually rather pedestrian; or, it was going to be one of those rare days that you know you’ll always remember. And then I was standing in Trevor’s kitchen as he produced a cardboard box and opened it up to reveal his finds.

I was astonished to see that he had indeed found a Late Iron Age helmet, made of copper alloy, along with a brooch in very good condition and a small spike made out of rolled copper alloy sheet. There was also a fragment of burnt bone which had been found together with the helmet and brooch; more bone had been observed but had not been removed. So it seemed probable the finds were derived from a cremation burial.

We agreed that it would be best to carry out a small excavation of the find spot as soon as possible to learn as much as we could about the context of this find.

A year later, what more do we know about it? It’s reasonable to set it in the context of the turbulent middle decades of the first century BC when the Romans, under Julius Caesar, were at war in what is now France. But it is very tempting to want to go further than this and see it as much sought after evidence of Caesar’s expeditions to Britain, and the county of Kent, in around 54 BC. The helmet seems of the correct design and the find spot lies along the probable route taken by Caesar’s army of about 20,000 men.

But even if this was the helmet of one of Caesar’s soldiers, there are many ways by which it could have arrived at its final resting place. The person (or persons?) whose remains are buried in it need not be its original owner. Perhaps it was brought by a warrior of the Cantiaci (Iron Age tribe), returned from fighting in Gaul with a trophy? Maybe it was a Gallic refugee? Or was the helmet handed down and buried years later (although the brooch suggests burial is unlikely to date much later than 50 BC)?

The finds are now undergoing specialist study at the British Museum, as part of the Treasure process, and this analysis will yield further information, as will investigation of the wider landscape around the find spot. We will certainly learn more about this find, but we may also have to face up to never knowing one way or the other exactly how and why it ended up where it did.

But what is certain, is that Trevor was right when he described this as a ‘significant discovery’.

You can now discover thousands of British Museum objects in partnership with @googleartproject at We’ve asked staff members to highlight their favourites and explain what makes them special. Chris Spring, Curator of Africa Collections, describes why he finds the ‘Throne of weapons’ so powerful. ‘This war memorial celebrates the ordinary people of Mozambique, many of them unarmed, who stood up to a culture of violence. It represents both a human tragedy and a human triumph. The Throne's essential humanity is suggested right away by its anthropomorphic qualities - it has arms, legs, a back and most importantly a face - actually two faces. My first reaction was that these faces are crying in pain, though they could also be seen as smiling faces finally freed from conflict. These anthropomorphic qualities also link it immediately to the arts of Africa, in which non-figurative objects such as chairs, stools, weapons, pots etc are seen as - and described as - human beings. The Throne has toured the world, taking its message of peace to schools, churches, shopping centres and even prisons – and of course, to museums and galleries.’ #MuseumOfTheWorld We’re celebrating our partnership with @googleartproject, and have asked curators to tell us about their favourite objects. Hugo Chapman, Keeper of Prints and Drawings, explains why he chose this chalk drawing by Michelangelo. ‘One of the things I love about drawings is the way they sometimes allow a glimpse into the private, behind the scenes world of an artist, one unseen in finished works in paint or stone. An example of that is a red chalk drawing by Michelangelo of grotesque heads in red chalk that reveal that the Florentine Renaissance artist had a lively, if caustic, sense of humour. The three heads were probably drawn to amuse but at the same instruct his pupils, as the three studies show how slight changes can radically alter the reading of an image with the character and mood of each figure (paranoid anxiety; vacuous joy; and depressive gloom) signalled by the position and erectness of their donkey-like ears.  I wish my ears were as expressive.’ Discover many more incredible works of art in the Google Cultural Institute at

#Michelangelo #art To celebrate our partnership with @googleartproject, we’ve asked members of British Museum staff to highlight their favourite objects and explain what makes them special. Jill Cook, Deputy Keeper of Britain, Europe & Prehistory, chose this stone chopping tool from an early human campsite in Olduvai Gorge, Tanzania. ‘Holding this 2 million year old African tool in my hand I am reminded that whatever differences exist between people now, we are united by our common origin in Africa. The discovery of this piece by Louis Leakey in 1931 began to change our understanding of what makes us human. It illustrates the beginning of a transition from an ancestral ape that walked upright on two legs within the confines of a limited ecological niche to humans with more complex brains capable of changing and eventually dominating the world around us by making tools and weapons. This chopping tool is one of the seeds from which all human cultures and societies have grown.’ Discover the stories of thousands of objects in the Google Cultural Institute at

#MuseumOfTheWorld In Victorian England many people were fascinated by their past, and the ancient tribal leader Caratacus (also spelt Caractacus) was adopted as a symbol of national pride and independence. Like Boudica, Caratacus resisted the Roman invasion of Britain. Although he was eventually defeated, he earned a reputation as a noble and worthy foe. The Victorian sculptor J H Foley portrays him here standing triumphant, the embodiment of courageous English spirit. See this incredible #Movember moustache in our #Celts exhibition, until 31 January 2016.

Here’s the Museum’s security team from 1902 photographed on the front steps. They include officers from the Metropolitan Police, and the London Fire Brigade (identified by their flat caps). We’re celebrating #Movember with Museum moustaches great and small. Here’s a #Movember fact: Peter the Great of Russia introduced a beard tax in 1698 and this token was given as proof of payment!
