Horizon (1964–…): Season 41, Episode 16 - The Lost Civilisation of Peru - full transcript
Two thousand years ago,
a mysterious and little known people
ruled the northern coast of Peru.
They built huge pyramids in the desert,
comparable in size to the great
pyramids in Egypt.
They were called the Moche.
The Moche were the Greeks of Andean
culture,
they created an exquisite society.
They built a culture of extravagant
wealth
and extreme violence.
This was a society obsessed with blood
letting,
we see it in the skeletal record and
we see it in the art and iconography.
Then the Moche simply vanished.
Tonight Horizon tells the story
of the rise and fall
of one of the greatest civilisations
of the ancient world.
It's an epic account
of human achievement,
natural disasters
and human sacrifice.

The Lost Civilisation of Peru
The Northern coast of Peru,
a remote desert area
sandwiched between the Andes mountains
and the Pacific ocean.
It's one of the most arid
regions in the world.
What geologists call a hyper arid
desert.
It's such a hostile environment,
everything struggles to live.
Yet there are signs that two thousand
years ago
something extraordinary happened here.
Dotted across the desert are a series
of strange shaped mounds.
Many are so heavily eroded that they
look like natural hills.
But close up it's possible to see
that they are made up of millions of
mud bricks.
They are known as huacas,
meaning sacred sight in the local
Indian dialect.
These are some of the oldest and
biggest man made structures in Latin
America.
But as scientists have investigated
the huacas
they found evidence that this was one
of the most remarkable civilisations
of the ancient world.
This is a huge archaeological complex
made up of a number of different sorts
of buildings.
But what really stands out are the
huacas.
Over there in front of us is
what's known as Huaca del Sol.
It's certainly the largest and possible
the most important monumental
building in South America.
And then facing it in front of this
large mountain
is a second and smaller huacas known
as Huacas De La Luna.
So what we're talking
about here is a complex
which would have been one of the most
important cities in South America.
These great cities must once have been
home to thousands of people.
Today we know this civilisation as the
Moche.
Careful mapping of the huacas
has enabled archaeologists to
reconstruct what they looked like
and how they might have functioned.
They were giant pyramids built as a
series of platforms.
The Huacas Sol over there
seems to have been made up of a number
of stages
at different levels.
In the centre was the tallest platform
and on top of it there were a series
of buildings with walls and roofs.
This may have been a spectacular
palace complex
where the rulers of this lost
civilisation lived.
We would have expected to contain a
number of large patios, corridors,
storage areas, kitchens,
and then residential chambers and
rooms where the rulers families would
have lived.
And we think the lower platforms may
have been more public areas,
spaces where ceremonies and receptions
were held for the wider general public.
Some of the pyramids are richly
decorated
and may also have been sacred centres.
Yet others doubled as burial mounds.
These were clearly the centres of a
rich and powerful people.
As archaeologists explored the
pyramids further,
they discovered the Moche
weren't just great builders,
but also great craftsmen.
At sites like this
they've uncovered a treasure trove of
some of the most remarkable artefacts
ever found.
The recent discovery of royal tombs
and ceremonial sites dedicated to the
Moche Gods
suggests that these people had reached
a cultural level
as advanced as the Greeks
and similar to cultures of the Middle
East, Egypt and the Mesopatamia.
They have also discovered sensational
metalwork and jewellery.
The Moche were pioneers of
metalworking techniques like gilding
and early forms of soldering.
It enabled them to create
extraordinarily intricate artefacts.
This is an ear stud,
it's one of the masterpieces
of the Moche goldsmiths.
And would have been worn by a Moche
ruler.
It's made of gold
with bits of turquoise mounted in it,
and it contains about one hundred
separate parts.
In the centre you can see an image of
someone.
In one hand he's carrying a large club,
the sort of weapon Moche warriors
would have carried
when they went in to battle.
Then there is the shield
and also a nose swing which actually
moves.
We're talking here about some of the
most spectacular jewellery ever
found anywhere in the world.
This was a society with many of the
hallmarks of a great civilisation.
The Moche built great cities with
massive monumental architecture.
They had a powerful political and
religious elite,
and they supported an artistic culture
capable of producing spectacular
pottery and metalwork.
But then, around 650 AD there is a
mystery.
Archaeologists found evidence that the
cities had been abandoned
and this extraordinary civilisation
seemed to vanish in to the desert.
The rise and fall of the Moche
raised tantalising questions.
How have they created such a
sophisticated civilisation in the
desert?
What kind of society was it?
And most fundamentally of all
what had happened to them?
The problem scientists faced
was that much about the Moche was
still shrouded in mystery.
They left no written record
and the people today have little
knowledge of the distant past.
Then archaeologists came across a new
clue
out in the desert.
Here they found signs of more Moche
construction projects,
an elaborate system of irrigation
canals.
Mud break aqueducts carried water tens
of kilometres,
many are still in use today.
This was how the Moche had tamed the
desert,
brought water to their cities,
and grown the crops that sustained
them.
But what was still missing
was any real insight in to how Moche
society worked.
There was however one important set of
clues,
the Moche left an extraordinarily rich
record of images and stories
on pots and vessels.
Many appeared to depict every day
scenes from the world around them.
But there were others that are more
unusual.
They appeared to depicts scenes from
an elaborate ritual,
a form of battle.
The war that they were fighting,
combat that they were doing
was a ritual performance and the idea
is
that one of them should be able to
knock down the headrest
or helmet of the other one.
If he does that one of the warriors
becomes a prisoner.
The scene then seemed to show the
prisoner being sacrificed,
his throat cut,
and the blood drained in to a goblet.
Once they have cut the throat they
would introduce a little tube
in to the jugular vein
so that the blood was easily flowing
in to the goblet.
The idea was to slowly kill them
and blood was drunk
by that supreme deity.
It was a gruesome scene of human
sacrifice.
But was it real or imaginary?
For many years scientists assumed that
the scenes were so grotesque
that they must be part of an elaborate
mythology.
Then in the mid 1990s
there was a discovery which would
thrown fresh light
on these gruesome images.
In 1995 Canadian archaeologist Steve
Bourget
started a new excavation at the Huacas
De La Luna.
We dug a number of trenches in the
ground to see what was there,
and found a series of human bones.
It occurred to us almost immediately
that this was not an ordinary burial
site.
Bourget and his team dug further.
The first bones were surrounded by
many more.
We dug an area of about fifteen metres
by ten metres
and found a whole number of human
bodies scattered around.
It was then that we
realised we'd found something
totally exceptional.
Nothing like it had ever been found at
a Moche site before.
Bourget realised that he needed
specialised help
to make sense of what he'd found.
The man he called in was forensic
anthropologist John Verano,
a specialist in bone analysis.
Verano still remembers it.
I ran in to Steve Bourget on the
street and he says
John I've got something that will make
you want to drop everything you're
doing.
And I said well great what is it,
and he said I've got you know more
bones than you can possibly imagine.
So we went out to the site
and they were just everywhere,
there was basically a field of
skeletons.
Bourget asked Verano to examine the
skeletons
and try to determine how they had died.
The first thing we started seeing
was in the, the neck bone.
We started seeing a series
of them with slim slash marks right
across the front of them.
These cut marks to get to the bone
would have to go through
all of the throat basically and some
very vital structures.
And so these are not just nicks that
would be insignificant,
they were a cause of death.
In other words,
these bodies have been cut across the
throat
so violently
that the knife had cut through to the
bone.
But this only accounted for some of
the cut marks.
We found cut marks not only on the
vertebrae,
but cut marks on the long bones.
In the middle of the shaft here,
on sometimes the wrist bones, finger
bones,
basically from head to toe some of
these people had cut marks,
hundreds of them.
Where the cut marks are located are
where muscles attach.
So they weren't cutting at the joints
and they were not
taking the bodies apart.
What they were doing was cutting
deeply and then pulling the flesh off,
pulling the muscles away from the bone.
Verano searched for an explanation.
Our immediate thought of course was
perhaps cannibalism,
where they'd taken the
meat off to consume it.
But what I found was they were so
careful in their cuts
they were removing flesh skin and so
on from areas
that were so difficult to de-flesh,
I think what they were doing in fact
was de-fleshing, taking the meat of
skeletons
to use those skeletons for a
particular ritual purpose.
It was a macabre finding,
but it proved that the pictures on the
pottery were not depicting
mythological scenes.
They were describing a real ritual,
or religious ceremony.
Scientists realised they'd uncovered
an all too real and brutal world of
human sacrifice.
It raised a fundamental question,
what in a Moche world was so important
it required the sacrifice of young men?
Was there a clue here
about how Moche society work?
And perhaps even to its fate.
Back at the sacrificial site
Steve Bourget now found
something he'd previously missed.
The first body we found
was sitting on a bed of solid mud.
But the big surprise was not
that we'd found a layer of mud,
what was interesting
was that the body was totally encased
in the mud.
So the sacrifice
appeared to have occurred at a time of
heavy rain.
It could have been a coincidence.
But as Bourget dug deeper
he came across the remains of earlier
sacrificial victims.
These two were so encased in mud
they had to have been buried during
periods of heavy rain.
Yet the Moche lived in a desert
where rain is extremely rare.
When we found the first body trapped
in mud
we thought straight away that it was
probably a one off,
an accident.
In other worlds
the Moche had just happened to
sacrifice somebody
during a heavy rainstorm.
We didn't think it
was very significant.
But when we found bodies that had been
entombed in mud
from different historical periods
we suddenly understood that some of
the sacrifices
had been deliberately performed in the
rain.
The sacrificial scenes suddenly made
sense.
Most desert societies have some form
of central ritual
to celebrate or encourage rain,
the Moche it seemed were no exception.
A regular and predictable pattern of
rainfall
would have been central to their
survival,
certainly worth the life of a young
warrior.
So what I think was going on
was that the Moche used human sacrifice
to try to maintain a relationship with
their God
and keep the natural world in harmony.
These were rituals
which they believed enabled them to
keep an unpredictable world in balance.
Here was a new insight in to Moche
society.
A harsh world had moulded a harsh
civilisation,
with an elaborate set of rituals
designed to ensure its survival.
Yet around 650 AD something had
changed.
Carbon dating on Moche sites
showed this highly sophisticated
civilisation
had suddenly vanished.
What had gone so badly wrong?
This was to become the great unsolved
mystery
of the Moche.
The first new clue was to come from a
totally unexpected quarter,
hundreds of miles from the Moche
settlements on the coast.
In the 1980s climatologist Lonnie
Thompson
travelled to the Andes.
He was hoping to trace back to ancient
times
the history of the region's climate.
Here there are glaciers containing ice
dating back thousands of years
and contained within them
is a record of the climate
at the time that they were formed.
Thompson knew that by collecting cores
from the ice
he would be able to read this record.
Each core is made up of a series of
rings,
each ring showing a different season.
Dry summers show up as narrow rings,
dark with dust.
Wet winters, when there was lots of
snow,
as broader clearer bands.
This pattern is the key to deciphering
the climate of the past.
The ice is a beautiful archive because
if you look at this you can see if you
start
on one end of the core you can see the
number of years.
This would be a dry season,
and from here is to here is a wet
season,
dry season.
The dry seasons are narrow in the cores
and stand out because
there's no snowfall.
There would be a lot more dust in this
layer,
and the wet seasons are broader
because that's when you
get the heavy snowfall.
This seasonal pattern can be used to
build up an annual picture.
Some sections of core consist entirely
of narrow dark bands,
indicating dry years.
Others have broad clear bands showing
wet years.
Almost immediately Thompson and his
team noticed something intriguing.
There seemed to be a close relationship
between the weather in the mountains
and the weather on the coast.
Over the last one hundred years
every time the ice core showed drought
in the mountains
it corresponded to a particular kind
of wet weather on the coast.
It's known as the El Nino.
A life giving period of rainfall
that arrives on the coast
once every five or so years.
The relationship seemed to be clear
and consistent.
Dry weather in the mountains meant wet
weather
and El Nino on the coast.
And the reverse was also true,
wet weather in the mountains meant a
drought on the coast.
It gave Thompson a powerful new tool.
In theory at least
he should now be able to trace back
the entire region's climate,
as far back as the Moche.
Armed with this new information
Thompson and his team set to work,
analysing the climatic information in
the cores,
back through time.
And when they reached the period
around 560 AD
they found something remarkable.
At exactly the time the Moche began to
collapse
the weather had gone haywire.
In an early period, starting about
560, 565 and going up to 600 AD
we found very distinct annual dust
layers
and in measuring the dust in the lab
we find extreme drought in this part
of the world.
Using the information in the ice cores,
Thompson estimated the drought in the
mountains to have lasted
thirty years.
And if his theory was right
it meant that there was an equally
extreme
but opposite climate pattern on the
coast.
This period from 565 to 600 AD
corresponds to a major
scale El Nino in the coastal areas.
And that El Nino would have been much
bigger than anything
that we have seen in the last five
hundred years.
This would have been something
absolutely huge.
It's what's known as a mega El Nino.
You get tremendous floods.
Houses get washed away,
communities get washed away.
But there was something else,
the ice cores also contained a second
story.
Further analysis showed that the years
of drought in the mountains
had been followed by years of heavy
snow.
After the dust event which terminated
around 600 AD
the annual layer show increase
thicknesses which relate to
a low period of wet conditions
following the drought.
Using his theory that what happens in
the mountains is reversed along the
coast,
it's suggested that the
mega El Nino on the coast
had been followed by a mega drought.
At least thirty years with no rain at
all.
This would definitely have disrupted
any type of culture, it would,
it would destroy a
culture in today's world.
Here was the suggestion of a huge
climatic cataclysm
between 560 and 650 AD.
The Moche would have been hit by a
double whammy.
Even a modern society would struggle
under these conditions.
It's the long term changes
that really bring about
impacts on civilisations.
First one, people bounce back.
Second one,
they come back, but they come back
slower.
After a while people get really
discouraged about having to try to
adapt to these changes.
If Thompson was right,
all the sacrificial rituals in the
world
would have been powerless to halt
such a catastrophe.
It was an intriguing idea.
But how reliable was it?
Archaeologists set out to look for
evidence of these two epic disasters.
Despite the dryness of the climate
all the pyramids show signs of severe
rain damage.
If you look over here
we found evidence of what looks like
major rainstorms going back many years.
Here for example
you can see how the walls are gushed
down the huacas
and formed these enormous gullies.
But if the rain will see them more
torrential and penetrated inside the
interior,
the colour of the building and the mud
bricks
would fall away in large slabs.
But was this the tell tale sign of a
mega El Nino,
or was the damage much more recent?
The frustration was that scientists
couldn't tell.
Then Steve Bourget digging at a Moche
site called Huancaco
made a breakthrough.
The site had been heavily damaged by
rain.
When we excavated the site
we found new construction work,
the town was being expanded.
Then we found evidence that the rain,
and not just the rain, but a river of
rocks and mud
had literally destroyed the new
construction.
So this disruption had definitely
occurred at the time of the Moche.
But when exactly?
The new floors and walls had been cut
in half by this river of rocks
and we could date destruction from
organic material left behind.
Bourget carbon dated these organic
remains,
the result was beyond doubt.
Archaeologically it's impossible
to determine exact dates,
but we estimate the new construction
ceased
some time between 550 and 600 AD.
It was the evidence archaeologists had
been looking for.
The dates were almost exactly the same
as the dates of Thompson's
mega El Nino.
Bourget had proved the Moche really
had been hit
by thirty years of epic floods.
But what about the second part of
Thompson's prediction,
the decades of drought?
New excavations at other Moche sites
now began to turn up evidence of huge
sand dunes.
Many contained artefacts which could
be dated.
And they showed that the sand had
started pouring in
some time around 600 AD,
after the mega El Nino.
It could only mean one thing.
At around 600 AD
the mega El Nino had been followed
by severe drought.
Thompson's second
prediction had been verified.
We would have had sandstorms that
would have hit the coastal sites
and completely covered them.
It's likely that most of the urban
infrastructure would
have been destroyed.
Here at last was a plausible
explanation
for the collapse of the Moche.
They had been overwhelmed by an
environmental catastrophe.
Thirty years of a mega El Nino
followed by thirty years or more of a
mega drought.
Everything went wrong at that point,
not only the economy, religion, the
leadership,
even at a personal level people were
in a state of complete despair.
It was a total disaster for a society
whose religion was based
on its relationship with the weather.
The whole belief system of the Moche
would have been called in to question.
Young men who until now had willingly
offered themselves as sacrifices to
the gods
must have wondered what the point was.
When a Moche, young elite member died
in a ritual sacrifice,
he was giving his life, not only to
the Gods but also to the state.
So if the elites show their weakness
by not being able to prevent the
calamity
why would people continue giving their
work, their labour, their products or
their lives.
It was a society that clearly was
based on something that was falsified.
The Moche had thought they could
control nature,
but found they couldn't.
It was a physical and ideological
catastrophe from which they never
recovered.
It all seemed to fit perfectly.
This became the accepted version of
events.
It seemed that one of the greatest
riddles in archaeology
had finally been cracked.
Then, in the late 1990s American
archaeologist Tom Dillehay
went to Peru.
Dillehay wasn't interested in
the famous Moche sites
with their huge pyramids,
instead he decided to survey some
little known Moche sites in a valley
known as the Jequetepeque.
What he found would shatter the
established theory.
When we do what we call a complete
survey,
it's a foot survey and
we cover the entire valley,
our purpose is to make sure that we
find every site,
including the large towns and urban
cities,
all the way back to farmsteads and
even small burial plots.
Many of the sites were so remote
they had never been explored before.
John Warner is a member of the survey
team.
Warner uses a specially adapted GPS
system
that maps the terrain
he's walking over.
It gives me a diagram, it gives me a
map,
it plots out where these various
features are across the landscape
and gives me a fantastic bird's eye
view of the relationship of
these objects to each other,
from a perspective that I would never
be able to achieve just from eye level.
The maps they created show walls,
floor plans and street patterns
that can't be seen from the ground.
Methodically Dillehay and his team
studied artefacts from dozens of
similar settlements.
But then they set about dating the
sites.
We're able to date most of these
sites in the valley
through excavation.
What we find are organic remains,
food, bone remains, trash, artefacts.
And at a number of sites we're
able to place these to
AD 650 to 700 years ago.
650 to 700 AD, it didn't make sense.
The accepted version of events was
that by 650 AD
the Moche had been destroyed
in an environmental catastrophe.
This was clearly not true.
The Moche had survived the
environmental upheavals.
And fifty years later
we're still building new towns,
until they finally disappeared
sometime after 700 AD.
It was time for some new thinking.
Dillehay's group returned
to the settlements.
One of the towns they studied was
called Cerro Chepen,
it's surrounded by an enormous wall.
The site itself is absolutely huge.
You can see the wall runs all the way
around it,
it runs all the way around my side
over here
and far beyond what I can see.
It certainly could have housed
hundreds if not
thousands of people during the Moche
period.
It looked like a massive hill fort,
nothing like it had been seen before
in the Moche world.
Further down the valley,
at a site known as JE125,
there was another important discovery.
Well this is really quite interesting
here,
this is the material that's
actually falling off
the hillside over here,
this jagged stone that breaks in to
angular pieces.
It was used to build a lot of the
defensive walls and platforms down
here.
And yet here we have these well
rounded river cobbles,
all piled in to sweet little piles
along this particular wall.
All placed about two to three metres
apart more or less.
The idea being that conceivably one
person could stand at each pile,
pick up a sling stone, insert it in a
sling,
swing it about and lob it down in to
the valley below.
These piles of stones here represent a
prehistoric ammunition.
Until now the Moche had never been
associated with anything more warlike
than ritualised combat.
But the evidence was unequivocal.
At around 650 to 700 AD,
well after the climatic upheaval,
the Moche had been at war.
But who with,
and could this explain what had
finally caused their collapse?
We began asking ourselves the question
what does this mean.
What does this sudden building of
fortresses mean across these valleys?
Are people fighting with foreign
troops coming in
from the highlands or perhaps areas to
the north of the south?
The most obvious assumption was that a
weakened Moche
had been invaded by a neighbouring
people.
The first option that came to us was
let's try and find more
evidence in these sites,
do more foot survey and see if we can
find
any evidence of foreign intruders.
Dillehay and his team scoured the area
looking for unusual artefacts
that might suggest the presence of a
non Moche people.
But there was nothing that suggested
any kind of outside invasion.
We started digging more and doing more
onsite inspection
of the kind of artefacts found at
these fortified settlements.
But we saw no evidence whatsoever of
any military weaponry
they're fighting with,
any foreign groups what so ever.
And we discovered that it's very
unlikely that foreign intruders
brought about this sudden building of
the fortresses in the valley.
But if there was no invasion,
why the commitment to defence?
There seemed to be only one other
possibility.
Dillehay now pulled together an
entirely new picture
of what had happened to the Moche.
What we see is a whole series of
climatic events, rainfall,
flooding,
and drought
that's putting stress on the economy.
And all of a sudden it collapses.
And the large ceremonial centres are
abandoned
and people start warring amongst
themselves.
Ritual violence had given way to civil
war.
They are competing for the best
agricultural lands,
the best fishing grounds,
and trading partners outside of the
valley.
The result was that people began to
move out in to the countryside
in these fortified settlements to
defend themselves essentially against
themselves.
It was the Moche's last stand.
A leadership that had failed to
protect its people lost control.
These people were playing the last
inning of their game,
they were playing the last round,
their last try.
They have build these temple,
they have build these city
to prove again that they were able to
control nature.
Something that they couldn't.
They were not the great society that
they thought
or they had been led to believe they
were.
They were as weak as any other society.
The Moche had survived rain,
they'd survived drought,
only to be torn apart by civil war.
One of Latin America's most powerful
and long lasting ancient
civilisations crumbled away.
Here was a new and much more
sophisticated theory for the demise of
the Moche.
Yet even this is not the whole story.
The more scientists look
the more they realise that in some
respects
the Moche never completely died.
Today along the coast of Peru
it's impossible to escape the legacy
of this lost civilisation.
Moche art lives on in the work of
local craftsmen.
And if you travel to the highlands
the Moche tradition of ritualised
combat
is preserved in the annual Tinku
ceremonies.
Here in a variation of the Moche
sacrificial rituals,
highland villages conduct ceremonial
battles against each other.
The aim is to spill the blood of the
opposition,
and fertilise the earth.
The Moche I think remained in the
memory of the north coast of Peru
as the great moment,
as their greatest achievement.
They were in a way the Greeks of
Andean culture.
Yet only now after fifteen hundred
years
are the Moche and their legacy
finally taking their place
in world history.

The Lost Civilisation of Peru
The Northern coast of Peru,
a remote desert area
sandwiched between the Andes mountains
and the Pacific ocean.
It's one of the most arid
regions in the world.
What geologists call a hyper arid
desert.
It's such a hostile environment,
everything struggles to live.
Yet there are signs that two thousand
years ago
something extraordinary happened here.
Dotted across the desert are a series
of strange shaped mounds.
Many are so heavily eroded that they
look like natural hills.
But close up it's possible to see
that they are made up of millions of
mud bricks.
They are known as huacas,
meaning sacred sight in the local
Indian dialect.
These are some of the oldest and
biggest man made structures in Latin
America.
But as scientists have investigated
the huacas
they found evidence that this was one
of the most remarkable civilisations
of the ancient world.
This is a huge archaeological complex
made up of a number of different sorts
of buildings.
But what really stands out are the
huacas.
Over there in front of us is
what's known as Huaca del Sol.
It's certainly the largest and possible
the most important monumental
building in South America.
And then facing it in front of this
large mountain
is a second and smaller huacas known
as Huacas De La Luna.
So what we're talking
about here is a complex
which would have been one of the most
important cities in South America.
These great cities must once have been
home to thousands of people.
Today we know this civilisation as the
Moche.
Careful mapping of the huacas
has enabled archaeologists to
reconstruct what they looked like
and how they might have functioned.
They were giant pyramids built as a
series of platforms.
The Huacas Sol over there
seems to have been made up of a number
of stages
at different levels.
In the centre was the tallest platform
and on top of it there were a series
of buildings with walls and roofs.
This may have been a spectacular
palace complex
where the rulers of this lost
civilisation lived.
We would have expected to contain a
number of large patios, corridors,
storage areas, kitchens,
and then residential chambers and
rooms where the rulers families would
have lived.
And we think the lower platforms may
have been more public areas,
spaces where ceremonies and receptions
were held for the wider general public.
Some of the pyramids are richly
decorated
and may also have been sacred centres.
Yet others doubled as burial mounds.
These were clearly the centres of a
rich and powerful people.
As archaeologists explored the
pyramids further,
they discovered the Moche
weren't just great builders,
but also great craftsmen.
At sites like this
they've uncovered a treasure trove of
some of the most remarkable artefacts
ever found.
The recent discovery of royal tombs
and ceremonial sites dedicated to the
Moche Gods
suggests that these people had reached
a cultural level
as advanced as the Greeks
and similar to cultures of the Middle
East, Egypt and the Mesopatamia.
They have also discovered sensational
metalwork and jewellery.
The Moche were pioneers of
metalworking techniques like gilding
and early forms of soldering.
It enabled them to create
extraordinarily intricate artefacts.
This is an ear stud,
it's one of the masterpieces
of the Moche goldsmiths.
And would have been worn by a Moche
ruler.
It's made of gold
with bits of turquoise mounted in it,
and it contains about one hundred
separate parts.
In the centre you can see an image of
someone.
In one hand he's carrying a large club,
the sort of weapon Moche warriors
would have carried
when they went in to battle.
Then there is the shield
and also a nose swing which actually
moves.
We're talking here about some of the
most spectacular jewellery ever
found anywhere in the world.
This was a society with many of the
hallmarks of a great civilisation.
The Moche built great cities with
massive monumental architecture.
They had a powerful political and
religious elite,
and they supported an artistic culture
capable of producing spectacular
pottery and metalwork.
But then, around 650 AD there is a
mystery.
Archaeologists found evidence that the
cities had been abandoned
and this extraordinary civilisation
seemed to vanish in to the desert.
The rise and fall of the Moche
raised tantalising questions.
How have they created such a
sophisticated civilisation in the
desert?
What kind of society was it?
And most fundamentally of all
what had happened to them?
The problem scientists faced
was that much about the Moche was
still shrouded in mystery.
They left no written record
and the people today have little
knowledge of the distant past.
Then archaeologists came across a new
clue
out in the desert.
Here they found signs of more Moche
construction projects,
an elaborate system of irrigation
canals.
Mud break aqueducts carried water tens
of kilometres,
many are still in use today.
This was how the Moche had tamed the
desert,
brought water to their cities,
and grown the crops that sustained
them.
But what was still missing
was any real insight in to how Moche
society worked.
There was however one important set of
clues,
the Moche left an extraordinarily rich
record of images and stories
on pots and vessels.
Many appeared to depict every day
scenes from the world around them.
But there were others that are more
unusual.
They appeared to depicts scenes from
an elaborate ritual,
a form of battle.
The war that they were fighting,
combat that they were doing
was a ritual performance and the idea
is
that one of them should be able to
knock down the headrest
or helmet of the other one.
If he does that one of the warriors
becomes a prisoner.
The scene then seemed to show the
prisoner being sacrificed,
his throat cut,
and the blood drained in to a goblet.
Once they have cut the throat they
would introduce a little tube
in to the jugular vein
so that the blood was easily flowing
in to the goblet.
The idea was to slowly kill them
and blood was drunk
by that supreme deity.
It was a gruesome scene of human
sacrifice.
But was it real or imaginary?
For many years scientists assumed that
the scenes were so grotesque
that they must be part of an elaborate
mythology.
Then in the mid 1990s
there was a discovery which would
thrown fresh light
on these gruesome images.
In 1995 Canadian archaeologist Steve
Bourget
started a new excavation at the Huacas
De La Luna.
We dug a number of trenches in the
ground to see what was there,
and found a series of human bones.
It occurred to us almost immediately
that this was not an ordinary burial
site.
Bourget and his team dug further.
The first bones were surrounded by
many more.
We dug an area of about fifteen metres
by ten metres
and found a whole number of human
bodies scattered around.
It was then that we
realised we'd found something
totally exceptional.
Nothing like it had ever been found at
a Moche site before.
Bourget realised that he needed
specialised help
to make sense of what he'd found.
The man he called in was forensic
anthropologist John Verano,
a specialist in bone analysis.
Verano still remembers it.
I ran in to Steve Bourget on the
street and he says
John I've got something that will make
you want to drop everything you're
doing.
And I said well great what is it,
and he said I've got you know more
bones than you can possibly imagine.
So we went out to the site
and they were just everywhere,
there was basically a field of
skeletons.
Bourget asked Verano to examine the
skeletons
and try to determine how they had died.
The first thing we started seeing
was in the, the neck bone.
We started seeing a series
of them with slim slash marks right
across the front of them.
These cut marks to get to the bone
would have to go through
all of the throat basically and some
very vital structures.
And so these are not just nicks that
would be insignificant,
they were a cause of death.
In other words,
these bodies have been cut across the
throat
so violently
that the knife had cut through to the
bone.
But this only accounted for some of
the cut marks.
We found cut marks not only on the
vertebrae,
but cut marks on the long bones.
In the middle of the shaft here,
on sometimes the wrist bones, finger
bones,
basically from head to toe some of
these people had cut marks,
hundreds of them.
Where the cut marks are located are
where muscles attach.
So they weren't cutting at the joints
and they were not
taking the bodies apart.
What they were doing was cutting
deeply and then pulling the flesh off,
pulling the muscles away from the bone.
Verano searched for an explanation.
Our immediate thought of course was
perhaps cannibalism,
where they'd taken the
meat off to consume it.
But what I found was they were so
careful in their cuts
they were removing flesh skin and so
on from areas
that were so difficult to de-flesh,
I think what they were doing in fact
was de-fleshing, taking the meat of
skeletons
to use those skeletons for a
particular ritual purpose.
It was a macabre finding,
but it proved that the pictures on the
pottery were not depicting
mythological scenes.
They were describing a real ritual,
or religious ceremony.
Scientists realised they'd uncovered
an all too real and brutal world of
human sacrifice.
It raised a fundamental question,
what in a Moche world was so important
it required the sacrifice of young men?
Was there a clue here
about how Moche society work?
And perhaps even to its fate.
Back at the sacrificial site
Steve Bourget now found
something he'd previously missed.
The first body we found
was sitting on a bed of solid mud.
But the big surprise was not
that we'd found a layer of mud,
what was interesting
was that the body was totally encased
in the mud.
So the sacrifice
appeared to have occurred at a time of
heavy rain.
It could have been a coincidence.
But as Bourget dug deeper
he came across the remains of earlier
sacrificial victims.
These two were so encased in mud
they had to have been buried during
periods of heavy rain.
Yet the Moche lived in a desert
where rain is extremely rare.
When we found the first body trapped
in mud
we thought straight away that it was
probably a one off,
an accident.
In other worlds
the Moche had just happened to
sacrifice somebody
during a heavy rainstorm.
We didn't think it
was very significant.
But when we found bodies that had been
entombed in mud
from different historical periods
we suddenly understood that some of
the sacrifices
had been deliberately performed in the
rain.
The sacrificial scenes suddenly made
sense.
Most desert societies have some form
of central ritual
to celebrate or encourage rain,
the Moche it seemed were no exception.
A regular and predictable pattern of
rainfall
would have been central to their
survival,
certainly worth the life of a young
warrior.
So what I think was going on
was that the Moche used human sacrifice
to try to maintain a relationship with
their God
and keep the natural world in harmony.
These were rituals
which they believed enabled them to
keep an unpredictable world in balance.
Here was a new insight in to Moche
society.
A harsh world had moulded a harsh
civilisation,
with an elaborate set of rituals
designed to ensure its survival.
Yet around 650 AD something had
changed.
Carbon dating on Moche sites
showed this highly sophisticated
civilisation
had suddenly vanished.
What had gone so badly wrong?
This was to become the great unsolved
mystery
of the Moche.
The first new clue was to come from a
totally unexpected quarter,
hundreds of miles from the Moche
settlements on the coast.
In the 1980s climatologist Lonnie
Thompson
travelled to the Andes.
He was hoping to trace back to ancient
times
the history of the region's climate.
Here there are glaciers containing ice
dating back thousands of years
and contained within them
is a record of the climate
at the time that they were formed.
Thompson knew that by collecting cores
from the ice
he would be able to read this record.
Each core is made up of a series of
rings,
each ring showing a different season.
Dry summers show up as narrow rings,
dark with dust.
Wet winters, when there was lots of
snow,
as broader clearer bands.
This pattern is the key to deciphering
the climate of the past.
The ice is a beautiful archive because
if you look at this you can see if you
start
on one end of the core you can see the
number of years.
This would be a dry season,
and from here is to here is a wet
season,
dry season.
The dry seasons are narrow in the cores
and stand out because
there's no snowfall.
There would be a lot more dust in this
layer,
and the wet seasons are broader
because that's when you
get the heavy snowfall.
This seasonal pattern can be used to
build up an annual picture.
Some sections of core consist entirely
of narrow dark bands,
indicating dry years.
Others have broad clear bands showing
wet years.
Almost immediately Thompson and his
team noticed something intriguing.
There seemed to be a close relationship
between the weather in the mountains
and the weather on the coast.
Over the last one hundred years
every time the ice core showed drought
in the mountains
it corresponded to a particular kind
of wet weather on the coast.
It's known as the El Nino.
A life giving period of rainfall
that arrives on the coast
once every five or so years.
The relationship seemed to be clear
and consistent.
Dry weather in the mountains meant wet
weather
and El Nino on the coast.
And the reverse was also true,
wet weather in the mountains meant a
drought on the coast.
It gave Thompson a powerful new tool.
In theory at least
he should now be able to trace back
the entire region's climate,
as far back as the Moche.
Armed with this new information
Thompson and his team set to work,
analysing the climatic information in
the cores,
back through time.
And when they reached the period
around 560 AD
they found something remarkable.
At exactly the time the Moche began to
collapse
the weather had gone haywire.
In an early period, starting about
560, 565 and going up to 600 AD
we found very distinct annual dust
layers
and in measuring the dust in the lab
we find extreme drought in this part
of the world.
Using the information in the ice cores,
Thompson estimated the drought in the
mountains to have lasted
thirty years.
And if his theory was right
it meant that there was an equally
extreme
but opposite climate pattern on the
coast.
This period from 565 to 600 AD
corresponds to a major
scale El Nino in the coastal areas.
And that El Nino would have been much
bigger than anything
that we have seen in the last five
hundred years.
This would have been something
absolutely huge.
It's what's known as a mega El Nino.
You get tremendous floods.
Houses get washed away,
communities get washed away.
But there was something else,
the ice cores also contained a second
story.
Further analysis showed that the years
of drought in the mountains
had been followed by years of heavy
snow.
After the dust event which terminated
around 600 AD
the annual layer show increase
thicknesses which relate to
a low period of wet conditions
following the drought.
Using his theory that what happens in
the mountains is reversed along the
coast,
it's suggested that the
mega El Nino on the coast
had been followed by a mega drought.
At least thirty years with no rain at
all.
This would definitely have disrupted
any type of culture, it would,
it would destroy a
culture in today's world.
Here was the suggestion of a huge
climatic cataclysm
between 560 and 650 AD.
The Moche would have been hit by a
double whammy.
Even a modern society would struggle
under these conditions.
It's the long term changes
that really bring about
impacts on civilisations.
First one, people bounce back.
Second one,
they come back, but they come back
slower.
After a while people get really
discouraged about having to try to
adapt to these changes.
If Thompson was right,
all the sacrificial rituals in the
world
would have been powerless to halt
such a catastrophe.
It was an intriguing idea.
But how reliable was it?
Archaeologists set out to look for
evidence of these two epic disasters.
Despite the dryness of the climate
all the pyramids show signs of severe
rain damage.
If you look over here
we found evidence of what looks like
major rainstorms going back many years.
Here for example
you can see how the walls are gushed
down the huacas
and formed these enormous gullies.
But if the rain will see them more
torrential and penetrated inside the
interior,
the colour of the building and the mud
bricks
would fall away in large slabs.
But was this the tell tale sign of a
mega El Nino,
or was the damage much more recent?
The frustration was that scientists
couldn't tell.
Then Steve Bourget digging at a Moche
site called Huancaco
made a breakthrough.
The site had been heavily damaged by
rain.
When we excavated the site
we found new construction work,
the town was being expanded.
Then we found evidence that the rain,
and not just the rain, but a river of
rocks and mud
had literally destroyed the new
construction.
So this disruption had definitely
occurred at the time of the Moche.
But when exactly?
The new floors and walls had been cut
in half by this river of rocks
and we could date destruction from
organic material left behind.
Bourget carbon dated these organic
remains,
the result was beyond doubt.
Archaeologically it's impossible
to determine exact dates,
but we estimate the new construction
ceased
some time between 550 and 600 AD.
It was the evidence archaeologists had
been looking for.
The dates were almost exactly the same
as the dates of Thompson's
mega El Nino.
Bourget had proved the Moche really
had been hit
by thirty years of epic floods.
But what about the second part of
Thompson's prediction,
the decades of drought?
New excavations at other Moche sites
now began to turn up evidence of huge
sand dunes.
Many contained artefacts which could
be dated.
And they showed that the sand had
started pouring in
some time around 600 AD,
after the mega El Nino.
It could only mean one thing.
At around 600 AD
the mega El Nino had been followed
by severe drought.
Thompson's second
prediction had been verified.
We would have had sandstorms that
would have hit the coastal sites
and completely covered them.
It's likely that most of the urban
infrastructure would
have been destroyed.
Here at last was a plausible
explanation
for the collapse of the Moche.
They had been overwhelmed by an
environmental catastrophe.
Thirty years of a mega El Nino
followed by thirty years or more of a
mega drought.
Everything went wrong at that point,
not only the economy, religion, the
leadership,
even at a personal level people were
in a state of complete despair.
It was a total disaster for a society
whose religion was based
on its relationship with the weather.
The whole belief system of the Moche
would have been called in to question.
Young men who until now had willingly
offered themselves as sacrifices to
the gods
must have wondered what the point was.
When a Moche, young elite member died
in a ritual sacrifice,
he was giving his life, not only to
the Gods but also to the state.
So if the elites show their weakness
by not being able to prevent the
calamity
why would people continue giving their
work, their labour, their products or
their lives.
It was a society that clearly was
based on something that was falsified.
The Moche had thought they could
control nature,
but found they couldn't.
It was a physical and ideological
catastrophe from which they never
recovered.
It all seemed to fit perfectly.
This became the accepted version of
events.
It seemed that one of the greatest
riddles in archaeology
had finally been cracked.
Then, in the late 1990s American
archaeologist Tom Dillehay
went to Peru.
Dillehay wasn't interested in
the famous Moche sites
with their huge pyramids,
instead he decided to survey some
little known Moche sites in a valley
known as the Jequetepeque.
What he found would shatter the
established theory.
When we do what we call a complete
survey,
it's a foot survey and
we cover the entire valley,
our purpose is to make sure that we
find every site,
including the large towns and urban
cities,
all the way back to farmsteads and
even small burial plots.
Many of the sites were so remote
they had never been explored before.
John Warner is a member of the survey
team.
Warner uses a specially adapted GPS
system
that maps the terrain
he's walking over.
It gives me a diagram, it gives me a
map,
it plots out where these various
features are across the landscape
and gives me a fantastic bird's eye
view of the relationship of
these objects to each other,
from a perspective that I would never
be able to achieve just from eye level.
The maps they created show walls,
floor plans and street patterns
that can't be seen from the ground.
Methodically Dillehay and his team
studied artefacts from dozens of
similar settlements.
But then they set about dating the
sites.
We're able to date most of these
sites in the valley
through excavation.
What we find are organic remains,
food, bone remains, trash, artefacts.
And at a number of sites we're
able to place these to
AD 650 to 700 years ago.
650 to 700 AD, it didn't make sense.
The accepted version of events was
that by 650 AD
the Moche had been destroyed
in an environmental catastrophe.
This was clearly not true.
The Moche had survived the
environmental upheavals.
And fifty years later
we're still building new towns,
until they finally disappeared
sometime after 700 AD.
It was time for some new thinking.
Dillehay's group returned
to the settlements.
One of the towns they studied was
called Cerro Chepen,
it's surrounded by an enormous wall.
The site itself is absolutely huge.
You can see the wall runs all the way
around it,
it runs all the way around my side
over here
and far beyond what I can see.
It certainly could have housed
hundreds if not
thousands of people during the Moche
period.
It looked like a massive hill fort,
nothing like it had been seen before
in the Moche world.
Further down the valley,
at a site known as JE125,
there was another important discovery.
Well this is really quite interesting
here,
this is the material that's
actually falling off
the hillside over here,
this jagged stone that breaks in to
angular pieces.
It was used to build a lot of the
defensive walls and platforms down
here.
And yet here we have these well
rounded river cobbles,
all piled in to sweet little piles
along this particular wall.
All placed about two to three metres
apart more or less.
The idea being that conceivably one
person could stand at each pile,
pick up a sling stone, insert it in a
sling,
swing it about and lob it down in to
the valley below.
These piles of stones here represent a
prehistoric ammunition.
Until now the Moche had never been
associated with anything more warlike
than ritualised combat.
But the evidence was unequivocal.
At around 650 to 700 AD,
well after the climatic upheaval,
the Moche had been at war.
But who with,
and could this explain what had
finally caused their collapse?
We began asking ourselves the question
what does this mean.
What does this sudden building of
fortresses mean across these valleys?
Are people fighting with foreign
troops coming in
from the highlands or perhaps areas to
the north of the south?
The most obvious assumption was that a
weakened Moche
had been invaded by a neighbouring
people.
The first option that came to us was
let's try and find more
evidence in these sites,
do more foot survey and see if we can
find
any evidence of foreign intruders.
Dillehay and his team scoured the area
looking for unusual artefacts
that might suggest the presence of a
non Moche people.
But there was nothing that suggested
any kind of outside invasion.
We started digging more and doing more
onsite inspection
of the kind of artefacts found at
these fortified settlements.
But we saw no evidence whatsoever of
any military weaponry
they're fighting with,
any foreign groups what so ever.
And we discovered that it's very
unlikely that foreign intruders
brought about this sudden building of
the fortresses in the valley.
But if there was no invasion,
why the commitment to defence?
There seemed to be only one other
possibility.
Dillehay now pulled together an
entirely new picture
of what had happened to the Moche.
What we see is a whole series of
climatic events, rainfall,
flooding,
and drought
that's putting stress on the economy.
And all of a sudden it collapses.
And the large ceremonial centres are
abandoned
and people start warring amongst
themselves.
Ritual violence had given way to civil
war.
They are competing for the best
agricultural lands,
the best fishing grounds,
and trading partners outside of the
valley.
The result was that people began to
move out in to the countryside
in these fortified settlements to
defend themselves essentially against
themselves.
It was the Moche's last stand.
A leadership that had failed to
protect its people lost control.
These people were playing the last
inning of their game,
they were playing the last round,
their last try.
They have build these temple,
they have build these city
to prove again that they were able to
control nature.
Something that they couldn't.
They were not the great society that
they thought
or they had been led to believe they
were.
They were as weak as any other society.
The Moche had survived rain,
they'd survived drought,
only to be torn apart by civil war.
One of Latin America's most powerful
and long lasting ancient
civilisations crumbled away.
Here was a new and much more
sophisticated theory for the demise of
the Moche.
Yet even this is not the whole story.
The more scientists look
the more they realise that in some
respects
the Moche never completely died.
Today along the coast of Peru
it's impossible to escape the legacy
of this lost civilisation.
Moche art lives on in the work of
local craftsmen.
And if you travel to the highlands
the Moche tradition of ritualised
combat
is preserved in the annual Tinku
ceremonies.
Here in a variation of the Moche
sacrificial rituals,
highland villages conduct ceremonial
battles against each other.
The aim is to spill the blood of the
opposition,
and fertilise the earth.
The Moche I think remained in the
memory of the north coast of Peru
as the great moment,
as their greatest achievement.
They were in a way the Greeks of
Andean culture.
Yet only now after fifteen hundred
years
are the Moche and their legacy
finally taking their place
in world history.
Someone needs to stop Clearway Law.
Public shouldn't leave reviews for lawyers.
