This is the story of how Britain came to be.

Of how our land and its people were forged over thousands of years of

history.

This Britain is a strange and alien world.

A world that contains the epic story of our distant prehistoric past.

From a time of Celtic glory, the owner of this is a man who is being seen by

followers as nothing less than a king to a new mysterious religion.

Whoever wore this was obviously a Christian, a believer.

And the technological breakthroughs that created whole new ages.

You've got the basis of mass production there, haven't you?

Today, modern science and new archaeology are solving ancient

and revealing the seismic shifts that transformed Britain.

It shows the way in which the Romans quite literally brought the modern

They brought the future with them.

The latest chapter in our epic story.

That's the lot of the Bronze Age miner.

God bless him.

From a golden age of bronze.

And then there's this magnificent cauldron. It's so modern somehow.

To a Britain in crisis.

Everything about this place says keep out.

A time of economic meltdown.

Sudden climate change.

And the dawn of a new era of Ireland.

I'm going back 3 ,000 years to late Bronze Age Britain, 1 ,000 years BC.

An island that is home to perhaps half a million people, living in farmsteads

and hamlets spread right across the land.

Here, on this wild stretch of Devon coastline, near the town of Throlcombe,

can see field boundaries clinging to that slope over there.

They're not modern. They're not medieval either.

In fact, they're around 3 ,000 years old.

These boundaries were created by self -sufficient Bronze Age farmers.

Up close, strangely enough, the lines are actually harder to see. It's because

they're so big.

The lines that were so obvious from over there are actually the bracken that's

growing on the real boundary, which is a heaped up earthen bank.

In this field, and in the fields that surround it 3 ,000 years ago, Bronze Age

farmers were growing oats and rye, or keeping cattle or sheep.

By the late Bronze Age, What we see emerging is a Britain that has the first

glimmers of a world that we would recognise today.

Permanent settlements with neighbours, people keeping animals and growing

and seeming peace and stability that has lasted for generations.

The Bronze Age was a kind of golden age in our history, one in which a warm and

generally favourable climate enabled a growing population to expand into newly

cultivated lands.

It was as if we had finally come of age after countless thousands of years of

dramatic struggle for survival and turbulent upheavals in society.

Our story first began in times so remote that the people who occupied Britain

were even a different species.

These are the oldest.

human remains ever found in Britain.

The Boxgrove Man lived half a million years ago.

From around 30 ,000 years ago, bands of modern humans came to Britain, hunting

the herds of horse and reindeer.

It's a fragment of horse bone with an engraving of a horse etched into it.

It's miraculous.

This was a struggle for survival in Ice Age Europe, when Britain was a

peninsula.

But when the ice retreated around 10 ,000 years ago, a new land of forests

rivers emerged, attracting new generations of

nomadic hunters.

Instead of hunting mammoth and reindeer in the snow, he...

hunted red deer in the wild wood.

As the ice continued to melt, sea levels rose, and by 6000 BC,

Britain became an island.

2000 years later, the first farmers came, bringing seed, livestock, and a

new way of life.

as well as sophisticated cosmological beliefs.

The illumination of this carving once a year in a piece of religious theatre lay

at the very heart of the beliefs of the people who designed and built this

place.

They created some of the greatest monuments in all of prehistory.

Vast passage tombs.

Stone circles.

And the monument of Stonehenge itself.

But the arrival of metal brought the Stone Age to an end.

From a time of cosmological priests, status now came from owning bronze.

No humble carpenter could possibly have dreamt of owning something so valuable

in the early days of bronze.

Much more than tools.

These are objects of desire.

Showing off.

Bronze Age Britain ushered in a new world of commerce and trade.

Opportunities to gain wealth and prestige.

the Devon Coast, a team of archaeologists is discovering a relic of

world.

The wreck of a trading vessel that sank here 3 ,000 years ago.

What are we actually looking for?

We're looking for ingots now. There's two sorts of ingots here. There's about

half of that and 10 ingots have been found on this lodge.

And that's precisely the two metals that you need to make bronze. I thought,

yeah. We're in 50 feet of water here.

How do we find the cargo?

Find the cargo with the metal detector.

Exactly like the sort of thing you'd use in a farm of steel, isn't it? It's

exactly the same piece of kit, really.

Looks like an electric shock waiting to happen. It does, doesn't it?

Three,

two, one, drop diver.

When the boat sank, It was laden with copper and tin, the valuable resources

the Bronze Age.

The boat's timbers have long decayed, but some of its precious cargo still

survive.

The falcon boat is evidence of an economy based on bronze and a modern and

mobile social class, the metal dealers of their day.

I've got a signal.

This is the first time the contents of this bag have been in the open air.

That's more than 3 ,000 years.

That's right.

Look at that.

Now that is unmistakable, isn't it? The heft of it, the weight, and the colour.

So how much of this material have you recovered?

Or have the team recovered? The team has recovered almost 300 ingots now, which

come to a total of about 85 kilograms.

But it wasn't only raw metal that went down with the boat.

Neil, this is a sword that was found two or three dives ago now.

Now that is a bit more recognisable than a copper ingot. Was that being moved as

metal or was it there as a sword fighting weapon?

I think this is somebody's personal possession for defence.

For defence of their boat and defence of their cargo.

The copper ingots are anonymous in a way.

By analysing samples of the excavated metal, scientists can discover more

the Salkham Rex cargo.

that that particular ingot did not come from Devon or Cornwall.

Copper contains an atomic signature that can reveal where it was mined.

We can link copper in Britain with a range of areas

in the continent.

Trading bronze wasn't confined to Britain.

This was an international economy.

from the Alps, Brittany, down through central France, Spain, maybe even

Portugal.

The falcon finds are revealing more than a coastal trading vessel, moving

cargoes of domestic copper and tin.

The boat that sank here 3 ,000 years ago was a link in a long chain of

international trade, which connected Britain to the very heart of Western

Europe.

through the exchange of bronze.

Metal had come to Britain 1500 years earlier, around 2500 BCE.

Brought by the first metal prospector arriving from continental Europe.

And amongst this dazzling array of grave goods is metal.

Look at this.

Here's one of them.

It's a copper knife. It would have been a wooden handle maybe coming out to give

you a grip on it near the cutting edge.

These are the oldest metal objects found so far in Britain.

But it was when copper was mixed with tin that a technical revolution

Turning two soft metals into a new alloy, hard enough to keep a sharp edge.

Bronze.

From liquid fire to a metal sword in a couple of minutes.

The Stone Age had been characterised by vast communal monuments.

But the Bronze Age would be different, with personal, domestic life at its

heart.

Unlike these massive stones, metal technology would make it possible to

work exquisite objects, the like of which had never been seen before.

A collection at the National Museum of Wales reveals just what late Bronze Age

workers were capable of after a thousand years of technological innovation.

All of these items were crafted around 700 years BC.

And there are all types.

There are socketed bronze axe heads, different sizes and weights.

The edge on this one has obviously been struck against something hard with

considerable force at some point.

But I particularly like this little item here.

This is a bronze razor for shaving.

And it's when you handle and see people like this that you get that sense of

real living people.

I have to say I've often wondered just how effective a razor like this would

have been.

I can just about imagine keeping facial hair under control with it, but I think

the idea of a modern clean shave...

It would still be some centuries in the future when this was in vogue.

And then there's this magnificent cauldron, also made of bronze. These

have been individually punched hundreds of times to take these hundreds and

hundreds of pointed, delicate rivets. And then there are the separately cast

hoop handles.

It really is fantastic.

The cauldron itself is a powerful symbol. There's more going on here than

cooking and feeding people because the cauldron for a long time was symbolic of

much more. It's about regeneration and it's about life itself.

And so this, whether or not it's being used for cooking, is a powerful, iconic

symbol.

Trade in bronze was fuelled by demand from a high -class elite.

Not everyone had the wealth for a bronze razor, let alone a feasting cauldron.

For those at the top, bronze was a material of desire, a source of status

wealth.

And right across Europe, people of means couldn't get enough of it.

Britain, on the far north -western fringe of Europe, was well -placed to

advantage of this infatiable demand.

And that was because of our natural resources.

Down in Cornwall, there were large reserves of a rare metal, tin, a key

ingredient in the manufacture of bronze.

Not for nothing was Britain later known as the Tin Island.

But as well as tin, you needed copper.

And just wait till you see.

what's further along this headland above Llanfidno in North Wales.

Great Orm.

The biggest prehistoric mine in the entire world.

The mining operation began here as an open -cast pit about 4 ,000 years ago.

That's 1 ,000 years before the Salkham wreck.

And once the surface deposits were exhausted, there was only one place to

Underground.

Miners hacked a web of tunnels down through the bedrock, penetrating over 20

metres below the surface.

I'm only fighting to manoeuvre my way through here.

What you have to bear in mind all the time is that Bronze Age miners had to

these holes through the rock.

And then, at the same time, removing the ore, getting it out, and

to spoil all the way the wrong kind of rock that they didn't want.

They had to get rid of that as well.

Just incredible.

Just have to turn on my back for a minute.

Oh my.

Just in front of me is the entrance to, well, to call it a tunnel.

It's like, it's about 20 centimetres wide.

It's back filled with rubble at the moment, but at some point, somebody was

there working.

Somebody very small, or more likely, I suppose, somebody very young.

It's just terrifying.

So far, archaeologists have excavated eight kilometres of tunnels,

and over half the network still remains undiscovered.

Enough ore was mined here to make around 2 ,000 tonnes of bronze.

Right at the heart of the mine, several of the copper veins converged.

And in excavating them, in mining them, the Bronze Age miner created

this enormous cavernous space.

Every... cubic metre of space has been created by people.

This is probably the largest prehistoric man -made chamber anywhere in the

world.

It's ironic that bronze itself was too valuable to use down here.

So the miners had to make do with rock and bone.

This is a...

bronze age hammer stone this would have been used to expose the ore but also

even more unbelievably I suppose to dig the tunnel imagine having to dig these

spaces out with tools no more sophisticated than this and then once

in here and once the copper was visible to them they turned to these this is a

rib bone from an animal it looked like a pick and it is a pick and it was used

to dig out the ore

Simple technology.

Of course, the glaring reality that I've been overlooking is the fact that

the miners then wouldn't have been able to use light.

If they had lit fires or used oil -burning lamps, the flames would have

consuming the oxygen that they depended on for their very survival.

So the only viable option was to work in the dark.

Like a whole collection of nightmares all in one place.

Confined spaces.

Tens of metres underground.

That's the lot of the Bronze Age miner.

Got metal.

For hundreds of years, the Bronze Age had sharpened divisions in society

the idea that status and wealth could be gained through the exchange of the

metal.

But now, the very bronze economy that had given some people financial

opportunity and social mobility was spinning out of control.

The insatiable appetite for bronze all across Britain and Europe went way

practical needs.

After all, there's only so many bronze axes that anyone needs to cut down a

tree. Instead, what we've got is bronze as a unit of exchange.

And it's this that's fuelling the digging of mines like the Great Orme and

international coastal trade.

By around 1 ,000 years BC, the Bronze Act has become a kind of proto

wealth divorced from its practical use as a metal.

And a bit like the economic bubbles that we see today, that's felt danger,

because a change in the attitude to bronze would have far -reaching

consequences, not just for the Bronze Age elite, but for all of British

By 800 BC, Britain, along with the rest of Europe, was heading for an economic

meltdown.

A golden era that had lasted for over a thousand years was about to end.

Bronze, the international currency of exchange, began to be dumped.

The astonishing display on this table is the Langton -Matraver bronze axe hoard.

They were found back in 2007 by a metal detectorist investigating a farmer's

field in Dorset.

At first he possibly thought he was just finding one or two of these, but then

it turned into dozens and then into hundreds.

And by the end he had nearly 400 socketed bronze axes.

Unbelievable.

Examination of them reveals that most were never used as axes.

They were made probably locally and then almost immediately buried in the

ground, deposited, discarded.

Huge amounts of buried bronze from this time have been discovered all over

Britain the moment when the economic bubble burst and axes like this became

but worthless.

These hoards mark an extraordinary turning point in our history.

Bronze, much sought after, much valued. The very base of power and exchange

across Britain and Europe was being thrown away.

But sometimes, discoveries from this time don't only contain bronze.

Back at the National Museum of Wales, the Llwynfawr hoard contained a new

technological wonder.

Alongside the bronze axes and the magnificent feasting cauldron, this

included a material that had never been seen in Britain before.

What makes this collection special is right here.

These are...

sickle for harvesting a crop.

These two are made of bronze but this one is made of iron and it's

one of the earliest iron objects ever found in Britain.

It's a stepping stone between two technologies because the craftsman who

this has used iron to create an object that looks as though it were made of

bronze. This spine here

would have been necessary to give the bronze blade strength, but it's not

necessary here.

The craftsman has still gone to the bother of creating it.

And the socket has been made by folding and hammering a flat piece of iron

into a tube, when it would have been much simpler and more practical just to

have a flat tang and haft it that way.

So it's as though the craftsman who was working with it was experienced in

bronze and is using his bronze -making experience as best he can

to try and work with this new material.

This marks the transition between bronze and iron.

It's the start of a whole new age.

Ironwork first appeared in the eastern Mediterranean around 1200 BC.

By 800 BC, it was beginning to be used by a new elite culture in central

This was the beginning of the Iron Age.

In time, Iron would transform Britain.

Not just technologically, but socially as well.

What we're seeing at the end of the Bronze Age and the beginning of the Iron

isn't as simple as an old technology being replaced by a new one.

Bronze had a role in society that went way beyond its practical uses as a

material for making tools to harvest wheat or cut up meat.

Its value as an exchange currency was the basis for social relations.

It had a ritual, even a religious significance.

Iron, though, would never have the same cachet as bronze.

And the new economy of the Iron Age would not be based on metal at all, but

agriculture, animals and grain.

In this Britain, Land would be at the forefront, and tribal chiefs would fight

for territorial power.

In 800 BC, though, all that was still to come.

Because, strangely, it seems that iron didn't actually come into use until

centuries after the Bronze Age ended.

And that leaves experts with one of the biggest problems in all of prehistory.

Apart from a few rare finds, like the Hlingvower treasures, there's just not a

lot of iron around in 750 BC, or indeed for hundreds of years thereafter.

This massive tipping point in our history, the shift from bronze to iron,

to have a mysterious gap in it.

It might be that even the remote existence of iron destabilised the

contributing to the end of the Bronze Age and a crisis that would last for 200

years.

Recent research, however, is suggesting that all this came at a time of sudden

and severe climate change.

By studying the larvae of Scottish midges from 750 BC, scientists are

evidence of a colder, wetter Britain.

Different midge species are happiest at different temperatures.

And when they find themselves in a lake that the temperature suits them, they're

going to be extremely abundant.

Preserved remains of midges from thousands of years ago can reveal the

they once lived in.

We find that around about 800 BC, there's a change in the composition of

midge assemblage, and we get an increase in cold water species and a decrease in

warm water species.

And this happens over a very short period of time, so probably around about

years or so.

And this corresponds with other evidence that we have from pollen and from pink

bogs, where the indication is that the temperature declined, but also

precipitation or rainfall increased at the same time.

In 750 BC, sudden climate change was a matter of life and death.

Too little rain or your crops would wither. Too much.

and there would be no ripening, no harvest.

Just as the bronze economy was collapsing, Britain's population also

possibly for the first time since the Ice Age.

This was a dual crisis that was driving Britain into a period of social turmoil,

a crisis that would utterly reshape British society.

An army training ground in Wiltshire contains the remains of over a century

massive regional gatherings.

I'm going to insist on arriving on site from now on. Absolutely, I think

everybody should have one of them.

Archaeologist Neil Sharples is finding clues to how people here were responding

to changing, frightening times.

This was a time of crisis.

So this is a time where there's a major transformation.

Bronze was used for all sorts of things, but primarily it's creating

relationships of status within communities. So when the bronze goes,

find social mechanisms to structure that society.

It's not too much to look at.

Wealth now was not measured in bronze, but in livestock.

And people came here to show it off in a new way.

Under our feet, there are thousands and thousands of pieces of broken -up

pottery, broken -up fragments of bone, carbonised plant remains, all the kind

implements and tools and debris of their lives on this spot.

There's quite a lot of material lying on the surface, but we can probably clear

away some of the nettles and we'll see it a bit clearer.

I mean, they're very large pieces of animal bone.

That's probably a cat. By

slaughtering

animals and sharing their meat, you could strengthen relationships and gain

prestige.

What I think we're seeing is we're seeing an attempt to create

between a fairly large region based upon feasting and based on conspicuous

consumption. So rather than by showing that you matter by having a particularly

expensive bronze object, you show that you matter because you've got all the

surplus food, surplus animals that you can just use up.

There's always someone who's bringing more food, killing more cattle, killing

more pigs, bringing cattle instead of sheep.

It's a way of creating distinctions. So you can structure...

and break it down into the really important people, the people with the

amount of wealth, access to good animals, access to good crops, access to

best quality pottery, that kind of thing. And the lowest, we've got, you

few sheep in a crubby little pot.

Remarkably, the remains of one man have survived from these times.

When he lived around two and a half thousand years ago, Britain was going

through a time of transformation.

It's safe to assume that he was a farmer.

And given the time in which he lived, he was probably dealing with a tougher

climate than that which had been known to his forefathers a few hundred years

before him. It was colder, wetter.

So he might have been experimenting with new crops.

He might have been keeping more livestock to compensate.

If he was a livestock farmer, then he may, from time to time, have taken some

the beasts to one of those midden sites and slaughtered them there to take part

in one of the great feasting rituals, the great feasting events.

But the way this man was buried gives clues not just to changing relationships

in life, but changing beliefs in death.

He was found buried in a pit, which sounds casual, almost as if he'd been

away. But it wasn't casual, there was ritual at play.

And we know that because he'd been laid to rest in the fetal position, curled

into a ball, and his knees were so tightly pulled up towards his chest that

death he must have been tightly bound up.

possibly in a funerary shawl or shroud.

For the longest time, the funeral tradition had been cremation. And so to

suddenly get burials, people being put into the ground intact, marks a change.

And that's always significant because a change in the way people are being

treated in death suggests that they were living differently, that life was

different.

The remains of another man.

who lived in Yorkshire 200 years later, is a clue to changing Iron Age beliefs.

When we found the skull in the ground, it was face down and there was only the

skull, the jaw, and a finger bone.

At the base of the skull were the first and second vertebrae of the neck, still

in position.

And basically that was it.

Remarkably, though, this skull still contained a 2 ,500 -year -old brain.

What this seems to be telling us, this brain, is that this person died very

quickly. Not only do we have remnant brain chemistry in here, but we have

remnants of the structure, the fine components within the brain.

But we don't have putrefaction, and it's usually putrefaction that destroys the

brain, turns it to soup in a very short time after death.

Perhaps this brain went into the ground very quickly after death.

The man's vertebrae preserved evidence of just how he died.

It's incomplete.

It's lost its arch across here.

And this is consistent with hanging.

And then we've got a series of very, very fine cuts, about nine cuts across

vertebrae. Somebody had taken a small knife... and felt their way through the

flesh to find the gap between the second and the third vertebrae in order to

take the head off the body.

This wasn't just a killing.

It seemed to be a ritual, a human sacrifice.

What you see in the early Iron Age is a change of beliefs.

There were offerings of valuables in the Bronze Age, but in the Iron Age... you

get more and more offerings of animals, and sometimes perhaps people as well.

It's as though people living through the Bronze Crisis and climate change felt

forced to reassess their lives and their place in the bigger scheme of things.

And for some, that was a path leading to a grisly end.

The period between 800 and 600 BC is one of the most mysterious in all of

prehistory.

And yet so much of what was going on resonates with our own age.

Economic collapse, fear of climate change.

But back then, there were no scientists or central banks to explain or to help.

The crisis affected everyone, though in different ways.

The end of bronze had a different impact in the north than it had in the south,

in the uplands and in the lowlands.

What we also start to see at this time is the beginning of something else that

we would recognise from Britain today, and that's the emergence of strong

regional identity.

As society became more locally focused, people began to find local solutions to

problems, local to them.

When Britain's climate began to improve once more, around 600 BC, with warmer,

drier summers,

the regions continued to develop in different ways.

In the far north of Scotland, people began to construct massive stone towers

called brochs.

Here at Gurness on Orkney there's a classic example.

There's banks and ditches encircling a little settlement of low stone houses.

but the whole scene is dominated by that wall.

And that's the base of a massive stone tower that at one stage would have stood

as much as 10 metres, 30 feet high, head and shoulders above the wall line of

any modern house.

And you can only imagine the impact that it would have had on anybody who came

to visit or attack here 400 years BC.

Little is known of the people who lived here, or what they believed, so we can

only speculate on the kind of society this was.

Here on the inside you can see the setting for an iron shod post that would

supported a big timber door that would have slammed shut against these stone

faces here.

These slots would have taken a massive timber that would have locked,

the door from the inside.

Everything about this place says, keep out.

Meanwhile, largely in the south, farming communities were creating something

very different.

Some of the most famous features of the Iron Age.

One of the best examples is at the top of this scree slope.

Which you see, Tricchiere, the town of the giant.

It's a hill fort, one of the iconic symbols of the age.

Tricchiere is actually quite a late hill fort.

But they start appearing over much of southern Britain from around 600 BC.

and they're often overlooking plains of fertile agricultural land.

The thing about these places is they weren't just defensive.

The term hillfort is pretty misleading. The threat of conflict wasn't always the

spur for their construction.

These were elevated places where people lived.

Some experts even think they were a kind of communist -style collective.

and they do certainly seem to be about sharing labour and sharing produce for

communal benefit.

Perhaps the development of hillforts bore some relationship to the great

gatherings, the local connections made through the sharing and display of

animals and grain.

These were farming communities, and when there was surplus production, seeds and

crops stored in storage pits could be exchanged.

Food, not bronze, represented wealth in this newly emerging world.

And the more land you could cultivate, the more successful your community could

be.

One thing that was common across Britain was that by around 500 BC, iron finally

began to appear in quantity.

Britain was at last about to embark upon the Iron Age proper.

After the initial impact of the Bronze Crisis, around 750 years BC, things

started to settle down.

From the Brochs in the north, to the hill forts in the south and west, and

manner of farmsteads and settlements in between.

By 500 BC, there was a kind of stability.

People had got over the seismic effects on the great international bronze

economy.

This was a turning point in our history, when iron finally began to appear

across Britain in increasing quantities.

It would change the way people lived. It would change the settlement of Britain

as a whole.

It would lead, in just a few hundred years, to the population increasing to

unprecedented levels.

And at its heart was a revolution in farming and food production.

Discoveries of ironwork from this time reveal an extraordinary leap forward in

technology.

These wee treasures here are some of the Thickerton tools.

They were deposited or discarded in Lincolnshire around 2 ,500 years ago.

It's a hammerhead.

Handle here.

The most obvious point of interest is the wear on the business end. That lip

been caused because that hammer has been used repeatedly, pounding against a

hard surface, probably used for hammering in iron nails, apart from

else.

This is a handsaw.

It's broken due to corrosion.

But this is the handle. It's made of antler.

beautifully worked and polished with lovely detailing to make it an

object as well as a useful one.

The blade has broken due to corrosion during 2 ,500 years.

It's so thin.

Some of that might be down to corrosion, but it would have been thin anyway

because a saw blade, in order to work, had to be thin.

That begins to show the versatility of iron over bronze because you couldn't

achieve that with cast bronze.

So this is a job for iron.

Possibly best of all is this one.

Now, you don't even need me to say the word, really.

But it's a file.

And see how the cutting edges have been so carefully

worked into that, cut into the metal.

It's so modern.

If someone was to show you this and say, this is from my great -grandfather's

toolbox, you'd be forgiven for believing them.

There's nothing different about it from the tools we use today, and yet it's 2

,500 years old.

The time of crisis.

was becoming a distant memory as the population of Britain grew rapidly.

Agricultural surplus lay at the heart of a newly emerging economy and that

depended heavily on iron.

Iron was a metal that could be hammered into all manner of shapes and forms, not

just half.

And unlike bronze, it wasn't the preserve of some elite.

Iron instead was the metal of the people, working tools for working men.

All of that, combined with its strength and its widespread availability, was to

transform our world and nudge it another step into the future.

Iron working became a part of village life right across Britain.

It's much better than the bronze because it's a little bit more elastic, so it's

not going to snap if you hit something hard.

And if it does bend, you can always straighten it again. If it breaks, you

weld the two pieces back together again.

And the iron also, you can sharpen and keep putting an edge on, save for a

sickle where you're cutting your corn or your hay.

You can keep sharpening it. It's much more versatile.

Bronze casting remained a specialist art, but anyone could heap and reshape

iron tool.

It's that sound as well, it's knowing that that ringing sound would have been

permanent background noise for our major village life. That ringing sound.

It looks best just while there's still a light in it, doesn't it? Because for

the rest of the time it's just going to be cold metal, but for now it's got

heartbeat. You can see it's dulling down and it's becoming utilitarian.

It's such a simple commonplace object. It's a tickle. Yeah, it's a tickle. At

the moment it's got the magic, hasn't it?

Iron had another advantage.

The ore was everywhere.

This was a metal that could be local. It didn't depend on a complex trade

network.

So by about 400 BC, as iron objects were beginning to appear in Erna, they

became ubiquitous, and the effects of the new technology were felt right at

cutting edge of the agricultural economy.

Right then.

Where are my mighty oxen?

Oh, yeah.

Oh, dear.

Right.

Oh.

What is this exactly?

It's an aard. It's a very early form of plough. It's basically a piece of tree.

Although, I'm guessing...

This one has the addition of an iron tip, yeah.

OK.

In the Bronze Age, then, they weren't ever tempted to put bronze tips on their

ploughs? It may have been tried, but unfortunately, of course, bronze doesn't

stand up to wear and tear the same.

With it being a casting, it's likely to break.

Right. And when it breaks, you have to make it molten and cast it again.

Whereas an iron tip, of course, you take it to the nearest fire, get it hot.

And hit it with something.

Oh, it's quite simple. If I could get the hang of a straight line.

And so these are starting to be visible from, what, 400, 500 BT? Yes, they are.

The later you go into the Iron Age, the more iron there is available and the

more people that are working it.

It wouldn't be hard to persuade people why this was a good idea.

They would very rapidly begin to see what the advantage was.

Yeah. Can we go for another one? Yeah.

Oh, disastrous.

It's a disaster for Scotland.

Iron ploughs allowed heavier soil to be turned so more land could be cultivated.

And there were other innovations that added up to an agricultural and

revolution.

How does it work? Why is a hole in the ground a good way to store grain?

I need to show you a finished hole. OK. Come over this way.

Oh, so there's a great big hole under there, is there? That clay cap is

a storage pit that's fully loaded.

Right. And what's the magic that that provides?

The clay cover keeps out moisture, air and light.

The grain that's inside the pit, where it's touching the walls of the pit,

moisture out of the chalk and attempts to germinate.

And, of course, in germination, you actually use oxygen to produce carbon

dioxide.

Because the pit is sealed, it runs out of oxygen and it hibernates. It actually

goes to sleep.

So time stops.

It does indeed, and for quite some considerable period.

You can actually store this quite safely a full year.

Occasionally we've got them to work for two years, so it's an enormous backup.

And you can well imagine how something like a reliable surplus of grain

becomes... Almost like money. You can almost spend it. On the hill forts

particularly, where you've got the extra space and the political control, then

we don't know how much was kept as a reserve by whoever it was that

that particular area. Your hill forts become a market town as well as a bank.

So you invent debt.

Yes. Yes, you could give a farmer grain who had an accident, and yes, then he's

in debt to you. He owes you one. Yes.

Trade in grain was the basis of this new agricultural economy, and new devices

were invented to process it.

Some of the very first machines.

For grinding grain, we use querns. You're probably looking at anything up

hour on a saddle quern. It looks incredibly primitive. Backbreaking.

You can tell from skeletons the wear and tear on bodies. A great leap forward

was the rotary quern.

The grain will go through several times. You're starting to see little flecks.

That's where the grain is actually being torn apart.

So it just keeps on going back in? Yes, you would just keep cycling it through.

It's just such a quantum leap. That's clearly, that's... Don't age.

This. It's got a design element about it. It's a composite tool, you know,

of multiple parts.

Huge time saver as well.

Iron Age housewives must have loved them.

Yes. And, of course, it frees up an enormous amount of manpower.

You can see how a momentum would build up. If you've got iron tools, you can

make more of these. You're producing more grain. Yes. These produce more

more bread. Yes. You can feed more people.

Yes. population increase.

Absolutely, yeah. And it'll just keep on building and building.

All these factors combined, plough, pit, stores, quern, and better

weather. The fields of Britain had probably never been so productive.

And from around 400 BC, there was a population explosion.

The crisis that followed the Bronze Age was over, and a new Britain was

emerging.

This bronze axe was the symbol of an age that had lasted for over a thousand

years, but it was a symbol of the past, a metal that represented a golden age

with its benign climate and international economy.

Bronze had created an elite, so it's not surprising that it had class overtones

as well.

There was also a spiritual aspect.

Bronze was about more than simply making tools. It was the glue that held

society together.

But this axe, made of iron, several hundred years later, never had that kind

value in itself.

The making of iron might still have been magical, but iron tools were

entirely practical.

And that set the tone for an age in which iron technology put agriculture,

therefore the land, at the very heart of society.

Wealth and power could be grown and stored, bought and sold.

In many ways, we'd lost something.

The magic of the Bronze Age replaced with something modern.

And what it would lead to would be power structures that compared to the Bronze

Elite would seem modern as well.

Next time.

My journey continues.

As I encounter a whole new age.

A time of powerful Celtic warrior.

He was laid in his grave.

And soon thereafter, three spears were thrust in.

Magical druid priests.

What events did he witness?

And what power did he wield?

and those at the very bottom of British society.

Look at this.

It's an iron slave chain.

It's over 2 ,000 years old.
