Rome, the Eternal City.

Today, it's a place
dominated by Christianity.

Its churches rule the skyline.

Its faithful pack the streets.

Every year, thousands upon
thousands of pilgrims

from across the world flock here
to worship in the place

that is truly the beating heart
of the Catholic faith.

For many, Rome's status as a holy
city begins with Christianity.

But in fact, its origin
as a sacred site

owes everything
to its pre-Christian past.

It was exotic pagan deities
who were first credited

with transforming a hillside village

to the capital of the most powerful
empire the world has ever known.

These were the gods of thunder,
love, war and wisdom,

who dominated the city
for a thousand years

and held its fortune in their hands.

The very ground Rome was built on
was considered sacred,

from its temples...to its sewers.

You can smell putrefaction,
the sweetness of waste.

But it also stinks of history.
It's a secret world lost in time.

This is a city
I've always been drawn to.

And in this series,

I'm going to be discovering just how
it gained its tradition of holiness.

I've come with the questions
of both historian and tourist,

to examine the fabric of a place

where power and religion
go hand in hand.

Rome has always been inspired

and shaped by its passionate
sense of sacred mission.

Popes and emperors,
kings and consuls have all believed

they served a higher purpose,
to fulfil the will of the divine.

And in this episode, I'm going right
back to Rome's pagan roots,

to a world of empires won and lost,
holy ambitions fulfilled,

a place where signs from heaven
could change the course of history

and men became gods.

I want to find out just how
this once-marshy wasteland

became one
of the world's holiest cities.

Every July, Rome celebrates one
of its favourite festivals.

It's a Catholic celebration in which
a statue of the Virgin Mary

gets a tour of Rome
along the River Tiber.

And she's off.

It's quite a bizarre sight,

the mother of God,
taking a ride on a motorboat.

But it does sum up Rome today.

Here, religious pageantry
is the city's daily theatre,

on the streets and on the water.

Christianity rules the Holy City.

But everywhere you look, paganism
lurks just beneath the surface.

Images of Mary on street corners
were once pagan shrines

devoted to the household gods.

Ancient temples have been absorbed

into the fabric of Christian
churches.

And the Pope has a pagan precedent.

The ancient Romans had their own
high priest, the Pontifex Maximus.

Even this procession has echoes
of the pagan world.

In 205 BC, there are stories
of the Magna Mater,

a foreign goddess,
being brought into Rome by boat

right up this river, just like this,

except it wouldn't have been
motorboats.

It would have been wooden boats.

It wouldn't have been balloons,
it would have been incense lamps.

But the modern, Christian Rome
of today, in many ways,

is not so far removed

from the ancient, pagan Rome
of gods and emperors.

And there's a clue to the origins
of Rome's timeless sanctity

in its founding myth.

Every sacred city needs a creation
story, and Rome is no different.

It's a tale that defined
the ancient Romans.

And as a tourist, it's a legend
you still can't escape.

There are glimpses of it
just about everywhere.

And here it is, two children
suckling a she-wolf.

It's a timeless vision
of human dreams and nightmares -

lupine ferocity
meets maternal nurture.

But it sums up everything the Romans
wanted to believe about themselves

and their city's destiny.

According to myth,

Rome was founded in 753 BC

by the twin brothers
Romulus and Remus.

Abandoned as babies,
they were rescued by a she-wolf.

And once adults,
they decided to found a city.

But it wasn't that simple.

Being brothers, they soon fell out
over where to build it.

Romulus wanted to build it
on the Palatine Hill.

Remus wanted to build it
on neighbouring Aventine Hill.

And to make the right decision,
they decided to consult the gods.

Signs from heaven were sent to each
brother in the form of vultures.

Remus saw them first,
six birds over the Aventine.

But Romulus saw more, twelve.

Each brother
claimed the gods favoured him.

It was a rivalry
with fatal consequences.

Romulus started to build walls
around the Palatine

to mark the boundaries
of his new city.

Remus mocked his brother by jumping
over the half-built fortifications.

It was a challenge, and Romulus
answered it by killing his brother.

The gods had spoken.

It's a legend that reflects
the Roman conviction

that this was a city whose fate
was divinely ordained.

So the story of Rome begins,
with religious omens

and murderous ambition,
power and religion -

the essential ingredients of
a holy city then, and now.

Of course, the story is a legend.

And the archaeology shows that Rome
actually started as a patchwork

of small farms on the seven hills
overlooking the River Tiber.

Between the hills,

there were marshy valleys where
the local people buried their dead.

Some time in the eighth century BC,

two villages that stood
on the hills,

the Palatine and the Quirinal,
merged into one settlement.

But there is one element
in the Romulus and Remus story

that does seem to have a basis
in historical fact,

and that is
that right from the beginning,

Rome was surrounded by a boundary
that was of enormous importance.

It marked Rome out as a sacred city.

This boundary was
known as the Pomerium,

and Romans thought
it originally followed

the line ploughed
by Romulus around the city.

But it wasn't just about
marking out territory.

Much more significantly,

the Romans believed the land within
it enjoyed divine protection.

This gateway,
known as the Arch of Dolabella,

was built on the line
of the Pomerium.

And to keep the gods happy,

there were strict rules
dictating behaviour

within Rome's sacred confines.

So on this side of the arch
was outside the city,

where the Romans believed you could
bury your dead or make war.

But as I walk through the archway,
I enter Rome.

Rome begins here,
and everything is sacred.

So if I was a soldier, for example,

I would have to leave my arms
outside the gate.

Generals could not build
military camps here.

The Romans believed that to break
these rules was sacrilege.

And this idea of what is
and isn't sacred space

has influenced the way
the entire city has been laid out.

It's why one of the main
thoroughfares into Rome,

the Appian Way,
is lined with tombs.

But only up to a certain point.

They stop the moment you enter
the city itself.

It's also why the tombs of the
early Christians, the Catacombs,

and on the outskirts
and not in the centre.

But the sacred space in Rome wasn't
just what you saw around you,

it also extended beneath your feet,
right underground.

Deep below the is one of its
most secret and holy sites.

It's a network of some sewers,

but they weren't just to wash away
the effluence of the Romans.

Like everything else in this city,
they also had a sacred purpose.

They were said to be the brainchild
of one of Rome's earliest rulers,

Tarquinius Priscus,
fifth monarch of the city,

and one of a line of kings
who ruled here.

The entrance to the sewers
is in the Forum of Nerva.

It's here that I met up
with Mark Bradley,

for whom they are
a personal passion.

Truly an elegant look
for la dolce vita.

The sewers are still in use today,
so precautions have to be taken.

How do I look?

I think we're ready to face
the effluvia of the ancients.

But I quickly realised that
penetrating these faecal caverns

wasn't going to be easy.

No way! I don't think
I can go down there.

I hate to tell you this.
I'm serious.

Nobody's ever fallen down it.

Don't like the look of it.

Half an hour later, after
a very 21st-century panic attack

that would have shamed
the noble Romans,

I managed to face
this terrifying abyss.

And as I descended into this
twilight canyon of filth,

I could smell it
before I could see it.

What a place! Oh, my God!

What is that?

This is absolutely
extraordinary down here.

Yes, these are terribly,
terribly important.

This is the Cloaca Maxima,
the great sewer,

which is the oldest surviving
intact monument in Rome.

Forget all the temples,
all the palaces,

this is the real start of Rome.

One of the main functions of these
sewers originally was to drain

the Forum, which was being
periodically flooded by the Tiber.

It's massive.
You can sail a boat through here.

And the Romans boasted about
sailing boats through here.

Come on, let's explore.

This extraordinary sanitation
system was built

right back in the sixth century BC.

And its tunnels stretch
for miles and miles.

For 2,500 years,
right up until the 19th century,

this was the only sewer system
serving the whole of Rome.

And the ancient Romans believed
it purified the city,

both practically and symbolically.

So, Mark,
why are these sewers sacred?

Well, these sewers are sacred,
in part, because they flush waste

out of the city, they cleanse
the city, they make it pure.

And there are shrines
marking particular points

and junctions in the sewer.

There is a very long-standing
tradition in the history of Rome

where unwanted elements of society -

so criminals, deposed tyrants,
even Christian martyrs - would be

cast down here, symbolically,
to be flushed out of the city.

Which emperors were actually
tossed down here?

The one emperor who is very famous
for this is the Emperor Elegabalus

in the early third century AD,

who was a depraved young emperor
who made a complete mess of Rome.

He was eventually assassinated,
his body was dragged, really foully,

through the sewers
and evacuated outside the city.

That's all that's left of one
of the last people to be here.

The Romans believed
this purging of the city

was key to its very survival.

If Rome was pure,
the gods would be happy.

And the city's fortunes
would be secure.

I actually didn't think
I'd be able to get down here,

but I'm so pleased I did.
I love it.

The stones themselves speak, perhaps
I should say stink, of history.

However disgusting it is down here -
and it really is disgusting -

the walls, the liquid,
the stink is appalling.

It's sweet in its horror.

And yet I have to tell you
there is real grandeur down here

and it is the sacred grandeur
of ancient Rome.

This splendid subterranean
world has shown me

that right from its inception,
Rome was regarded as a holy city,

above and even below the surface.

Oh, my God! How lovely!
Sunlight, air!

Goodbye, ancient tunnels of Rome.

The sewers are one of Rome's
best-kept secrets.

But they have an unexpected link
to one of the city's

most popular tourist destinations
that might not please

the thousands of people
who come here.

The famous Bocca della Verita,
the mouth of truth, has been linked

since Middle Ages to a tradition

that if an unfaithful lover
put his or her hand in the mouth,

it would be bitten off.

In Roman times, it wasn't a good
idea to put your hand in that hole,

whether you were faithful or not.

This is in fact
a monumental sewer cover,

decorated with the face of
Oceanus, God of the oceans.

The risk was not so much
from infidelity as from infection.

The concept of Rome as a holy city
was present from the beginning.

And it not only shaped how
the Romans designed their city,

it also influenced every political
decision its rulers made.

The Romans were obsessed with
the gods and their moods.

And that governed how they behaved
from dawn till dusk.

Every soldier, every Caesar,
believed he had a religious role.

To commemorate the greatness of Rome
was to celebrate its holy destiny.

In this city, religion and politics
were inseparable bedfellows.

Nowhere is this marriage of sacred
and secular more blatant than here.

At the Forum,
the heart of pagan Rome.

It was first built in the sixth
century BC as a civic centre

after the sewers were established
and the land drained.

And for 1,000 years, it was
the centre of Roman public life.

Here, speeches were given, criminals
were tried, laws were made.

And temple after temple was raised
to the glory of the gods of Rome.

According to legend, this was home
to another king of the city,

whose influence shaped the earliest
traditions of Roman life.

His name was Numa Pompilius.

The Romans believed
that it was Numa who created

the religious rituals and structures
that made possible the rise of Rome.

And he did it right here.

When you visit the Forum
for the first time,

you're both dazzled and bewildered.

It's a mishmash of architectural
fragments from different ages.

There are traces of temples
built and rebuilt.

Layer upon layer of Roman history.

Much of what stand here today
belongs to the time

of the emperors,
the last leaders to make their mark.

But the origins of this site
can be dated right back to

the period of the Roman monarchy.

King Numa was said
to have established
four colleges of priests,

with very clear responsibilities.

They were not just religious,
they were also political.

And without their say-so,

the entire routine of Roman politics
would grind to a halt.

All buildings in the Forum,
public or private,

were dedicated to the gods.

And all political decisions
had to be made

on sanctified ground - from
holding elections to passing laws.

So it was a group of priests
known as the augurs

who had the final say
over planning decisions.

This was the Senate house,

but it was also something called
a "templum", a sacred space.

The augurs would consult
the heavens to approve the site

and then map it out
with holy staffs.

It was as if
the Houses of Parliament

stood on a sacred rectangle.

And if the space wasn't sacred,
the decisions weren't valid.

At the opposite end
of the forum was the Regia.

It was the royal residence,

originally thought to be
the Palace of King Numa

and the seat of secular power.

But it was also the centre
of religious control.

This was once the headquarters
of the Pontifex Maximus,

the high priest, the supreme
religious authority of Rome

and Pontifex Maximus literally means
"the greatest bridge-builder".

He was the bridge
between gods and men.

He regulated the rituals
of Roman life and the divine law

and this gave him
considerable political authority.

But he was also a master
of the Vestal Virgins

and right next door
to his headquarters

was their house and temple.

The Virgins
were priestesses of Vesta,

the goddess of the hearth and home,

who had a special link to
the fortunes of the entire city.

The Vestal Virgins
were chosen at the age of six

for their moral
and physical perfection.

Their task was to tend
the sacred flame

of the sacred hearth of the city

and the Romans believed
that if the fire went out

the city itself would fall.

The whole forum was a place
where religious practice

ensured Rome's political decisions
had divine backing.

I've always been fascinated
by the macabre rituals

that really decided
the destiny of Rome.

So I asked Mark Bradley
to give me an insight

into the work of a priestly group
who were involved

in one of the gorier aspects
of Roman politics -

they were known as the haruspices,

diviners from the Etruscan
communities of northern Italy,

skilled in interpreting
signs from the gods.

And there's a reason we're meeting
in a fresh food market.

So, Mark, what is this still-warm,
almost pulsating bloody organ

that we have here on the platter
in this butcher's shop?

Well, this is a fresh liver
taken from a newly sacrificed sheep.

What the priests would do
is they'd cut open the animal

and they'd take out the liver
while it was still pulsating

and they'd examine it
to see what the future has in store.

So the first thing we need to do
is orientate it correctly.

What the haruspices did is
they used a model of the liver

to guide them, to remind them,
to prompt them about how to read it,

so what we have here
is a bronze model of a liver

from about 100 BC and this is called
the Piacenza Liver,

and on this you can see
the gall bladder, the caudal lobe,

and the liver was divided
into 16 sections

and these 16 sections corresponded
to the 16 regions of heaven

and each region was governed over
by a particular god.

So what we'll do
is we'll have a look at this liver
and see what it tells us.

So this area here,
around where the gall bladder was,

is an area governed by war gods

and if you find a discolouration,
a tumour, a blood clot,

a bile pool or something like that
in this area,

that might mean that
the war gods are not happy,

this might not be
a good time to go to war.

Another area that's very interesting
is all of this area

which is associated
with the Etruscan god Tin,

who is the equivalent
of Jupiter in Roman cult.

If he's not happy you need to
make a sacrifice to him

or you need to build a temple to him
or something like that.

OK, so if I'm an emperor,
my legions are massed

and I now want to invade Germany
today and destroy the German tribes,

can I march today?
Can you read the organ?

Well, this liver
is remarkably clean.

This is absolutely unblemished,
as far as I can see.

This is a good time to do
pretty much anything.

I'm happy, call in the centurions -
we march today. Absolutely.

If religion was an essential
part of a politician's life,

for your ordinary Roman
there was barely a beat in the day

that wasn't overseen by a god.

Buon giorno.

For the average Roman farmer,

it wasn't just about sowing,
ploughing and reaping.

To get a bumper harvest they had
to keep the gods happy, too.

In April there was
the Festival of Cerialia

dedicated to the goddess of grain,

which involved heading out to
the Circus Maximus in the evening

to watch foxes with torches
tied to their tails.

This, apparently,
protected the crops from vermin.

And then there was the Festival to
the god Robigus who governed mildew.

To avoid an outbreak,
farmers had to sacrifice a dog.

And in October,
to thank Mars for the harvest,

it was a horse that got the chop.

And private rituals were
as important as public festivals.

Families prayed daily to
the household gods, the Lares,

whose statues they kept at home
in special niches.

And they gathered for ceremonies
in the fields to offer sacrifices,

ensuring the crops would ripen.

In fact, the Roman farmer
had so many religious obligations

it's a wonder he had any time
to tend his crops.

The religious structures
and practices said to have been
established by King Numa

largely formed the basis
of Roman religion

for the entire first
millennium of Rome.

But in 509 BC
a political crisis broke out.

A group of aristocrats rebelled
against the king, Tarquin the Proud.

They overthrew him and established
a new political system.

Rome would no longer be ruled
by one man but by the Senate,

an assembly of its leading citizens.

The Roman Republic was born.

But whatever ideas drove the change,

religion remained at the heart
of the new regime.

Indeed, the more successful Rome
became, the more sacred the city.

The dawn of the Republic
was marked by an event

that would have seen the whole
of Rome celebrating on the streets.

It was the dedication ceremony

of a building that once stood here
on the Capitoline Hill.

The single most important temple
ever erected in Rome.

On 13 September 509 BC,

this spot above the forum would have
been packed with people.

And what an awesome spectacle
it would have been.

They were there for the dedication
of the vast new temple of Jupiter,

Optimus Maximus, the biggest
and brightest of the Roman gods.

There was an altar outside
for sacrifices

and the doors were always open

so passers-by could see the huge and
gaudy statues of the gods within.

For a Roman who was there that day

it would have been as magnificent
as it was unforgettable.

The entire ceremony was designed
to remind the Roman people

that the god Jupiter
was the source of Roman glory.

And for the new Republic,

this building marked a dramatic
moment in the city's history.

This was the opening ceremony

of the first pagan cathedral
of republican Rome.

The only surviving sections
of the temple

are now in the Capitoline Museum
in their original position.

Matthew Nicholls
believes it is a building

that encapsulates the sacred
ambitions of this new regime.

What we're looking at here, Simon,

is a wall that forms part of the
foundations of the Temple of Jupiter.

It's not the temple itself,
it merely the foundations

that built a huge platform
on which the temple sat.

And how big was it? It was enormous.
It was awe-inspiringly huge.

You've got to imagine a podium
that was perhaps the size

of two Olympic swimming pools
side-by-side

with the temple itself
sitting up on top of that.

So this dominated central Rome?
This dominated the forum?

It looked down on the forum,

it looked out across
the hills and valleys of Rome.

It could be seen from a long way away
and it was a magnificent sight.

Who built it and what was
its political significance?

Its significance
is really what it tells us

about the ambitions
of the Roman state.

It was linked
right from the start to conquest

and the divine mission of conquest
the Romans felt they had.

But even though we associate
this temple very closely

with the Roman Republic
and the many rituals of the Republic,

in fact it was planned,
it was conceived,

when Rome had kings,
was ruled by Etruscan kings,

and the last of them,
Tarquinius Superbus,

was responsible for almost bringing
this temple to fruition,

and then his rule was blown away
in the revolution.

So why did the Republic adopt
this very royal enterprise?

Romans loved the idea that their rule
and their growing empire

was sanctioned by the will of heaven,
that this was a mission

that the gods entrusted
to them as a people.

Even when the kings were gone,
the Roman people
could carry that mission forwards.

The building of this temple

marked a watershed
in the history of the whole city.

It was the moment
when Rome transformed

from being a town of small-scale
temples and shrines

to a sacred capital
embellished with its own cathedral.

The Temple of Jupiter
was a declaration

of the astonishing religious
and political confidence of Rome,

a rising power blessed and propelled
on its sacred destiny

by the forces of the gods.

And that power was consolidated
by the raising of ever-more temples.

Their remains can still be seen
all over Rome.

As the Romans conquered
new territories,

the spoils of victory
poured into the city

and since the Romans attributed
their success to the gods,

so the victors built
more and more magnificent temples

in gratitude and in celebration.

Gradually the geography
of the Holy City

began to resemble a map
of Rome's ever-increasing empire.

And nowhere was Rome's
acknowledgement of the gods clearer

than in one of the city's
most colourful military ceremonies.

When a general returned
from a victorious war,

the Senate voted him
something called a Triumph,
a parade through the city.

He rode in his chariot
followed by his army,

by wagons heaped with booty

and by his shackled prisoners

and he ended up right here
at the Via Sacra, the Sacred Way,

the most important street
in the Roman forum.

Imagine the excitement.

The general wearing purple and gold,
his face painted scarlet.

He was dressed as Jupiter for a day,

but in case the glory
went to his head,

a slave rode behind him
in his chariot whispering,

"Remember - you are only mortal."

His procession ended, of course,

at the Capitol
and the Temple of Jupiter

where he laid laurels at the feet
of the giant statues of the gods.

At that moment there'd be no doubt
in any Roman's mind

that the gods were responsible
for the city's fortunes.

But the success of the Republic
came at a price.

It was the purity of Rome's religion
that suffered.

The city's expansion into
a vast empire

led to an influx of foreigners
from Greece to Egypt.

And with them came their gods.

Rome's senators could have
suppressed these new divinities

and stayed faithful to their own,

but they took
a more pragmatic approach.

Foreign gods, like Isis and Serapis,

were absorbed into the state
religion and in the third century BC

one was even imported
to try and avert disaster.

In 205 BC, Rome faced
one of its gravest crises.

For almost a century, the city
was engaged in a power struggle

for control of the Mediterranean.

Its enemy was Carthage, led by
the brilliant commander Hannibal.

And it was a threat
that led to the introduction

of one of the most flamboyant and
exotic new goddesses to the city -

just in the nick of time.

Rome's very existence was in peril.

Strange portents and mysterious
hailstone storms threatened danger

and in their panic the Romans decide
to consult the Sibylline Books,

sacred texts
kept in the great Temple of Jupiter.

Their advice was clear -

in order to avoid defeat
by Hannibal and the Carthaginians,

the Romans must import
a foreign goddess from Asia Minor.

Her name was Magna Mater,
the great mother,

and her arrival in the city

and her acceptance
as one of its official gods -

that alone would help save Rome.

The Roman historian Livy
wrote a vivid description

of her arrival in the city.

The goddess was shipped up the Tiber

accompanied by her cult officials
known as the Galli -

self-castrated eunuch priests.

And when she arrived
at the river's bank

she was born through the city,
passed from hand to hand.

The whole of Rome
came out to meet her.

Incense burners lined the streets

and all the Romans prayed that she
would enter the city willingly.

It seems Rome hasn't changed
as much as you might think.

LOUDSPEAKER CHANTS

Shortly after her arrival,

Magna Mater was given a home
at the very centre of the city -

a temple on the Palatine Hill -

and her rituals were incorporated
into the official calendar.

Three years later,
Hannibal was defeated.

The story of Magna Mater
shows how far Rome had come.

It transformed from sacred village
to a holy city

dedicated to a multinational
pantheon of deities.

But in the first century BC,
700 years after its foundation,

the whole city
was to become a shrine

not just to the gods, but to a man.

And one man in particular.

It was an innovation
that had its roots

in the rule of one of Rome's
most outstanding leaders...

..Julius Caesar.

Caesar's rise to power
came at a time when violence,

cynicism and corruption
had taken hold of the Holy City.

As the empire grew, the struggle for
control became more and more vicious

and religion was ripe
for exploitation.

Portents from heaven were
interpreted to justify decisions.

Omens and oracles were invented
for political advantage.

And in this world,
one man stood out.

Caesar was so exceptional,

the Roman state
was almost too small for him.

Nicknamed by his own soldiers
"The Balding Adulterer",

he was a gambler, a risk-taker,

and he was an arch manipulator
of religion

for his own political ends.

He even claimed to be descended
from the goddess Venus herself.

But his success provoked
the jealousy and suspicion
of the other nobles

with deadly consequences.

This little-known square
is the closest you can get

to the spot where Caesar
was murdered.

In the first century BC,
these ruins were temples.

And on the Ides of March 44 BC,
Caesar was passing here

when he was stabbed
by a group of conspirators.

At first he fought back,

but when he saw
among the assassins was Brutus,

his mistress's son whom he adored,
he gave up.

His murder was meant to save
the Republic,

but in fact it just accelerated
the end of the dream.

With Caesar's successors,

Rome would no longer be ruled
by the Senate as a republic

but by a single ruler
as an autocracy.

And with this new political order
came an innovation in Roman religion

which would once again have a huge
physical impact on the Holy City

and on the daily lives of
the ordinary people who lived here.

The Emperor wouldn't just be

the most powerful political leader
in the western world -

he was about to become
the son of a god.

Caesar's heir was his 18-year-old
nephew, and adopted son, Octavian,

a brilliant political strategist,
who combined the old and the new

to give Roman leaders a new status.

They were no longer just
generals and priests -

they could also be gods.

After Caesar's death,
Rome was thrown into chaos

and a fight for power
ripped the city apart.

Octavian found himself in
a bitter struggle to rule the Empire

against Caesar's right-hand man,
Mark Antony.

Mark Antony allied himself with
the irresistibly vampish

and hugely ambitious Queen of Egypt,
Cleopatra.

Together, they embraced an Eastern
version of power and religion.

But Octavian cleverly used this
to turn the Romans against them.

Antony and Cleopatra were defeated
in battle and committed suicide.

He by sword, she by snake.

And Octavian became
Rome's first emperor.

Octavian's victory marked a crucial
turning point in Rome's history.

Under his regime,
it became the most magnificent

and sacred capital
of the Western world.

Romans began to call it
"the eternal city".

And Octavian had similarly grand
ideas about his own status.

When Octavian became emperor,

he adopted a new name
for his new role - Augustus Caesar.

Augustus means
"consecrated by the augurs".

It was a name that evoked
the favour of the gods

and the auspices that marked
the founding of Rome.

The name Caesar also linked Augustus
to his murdered uncle, Julius.

And very early on, he had a temple
built here, in the Forum,

in his uncle's honour.

It doesn't look like much now,

but this once dominated
the entire south side of the Forum.

Before it was built, this was where
they brought Julius Caesar's body

after his assassination.

And it was here that they
cremated him before huge crowds.

The temple marks a major change
in Roman religion.

This is when they started
to treat their rulers not as men,

but as gods.

On 1 January 42 BC, the Senate
passed an unprecedented decree.

They declared Julius Caesar divine.

It made him the first historical
Roman ever to be officially
deified.

With a temple and priests, this
mere mortal had now become a god.

And if Julius Caesar was a god,
then his adopted son, Augustus,

had a new title - Divi Filius,
son of a god.

But Augustus's desire for divinity
wasn't satisfied by a title alone.

He spent the next four decades
taking steps which gradually tied

Roman religion not just to the city
of Rome, but to a single person -

the Emperor.

And he did it
through a vigorous programme

of rebuilding and religious renewal.

He reinstated ancient
religious festivals,

rebuilt crumbling temples,
filled vacant priesthoods.

He claimed he was restoring Rome's
ancient past to please the gods.

What he was really doing
was making Rome his own.

Augustus subtly co-opted new powers,

taking on the mantle of all
the major priesthoods in Rome,

culminating in 12 BC,

when he declared himself
Pontifex Maximus.

Five years later, he divided
the city into new districts.

And on every street corner,
he built a shrine.

In his meticulous way,

he was altering the whole focus
of Roman worship.

Very few traces of these
ancient shrines remain,

but there's one
in the Vatican Museum.

It's tucked away from public view
in the Pope's own private gallery.

And its carvings show just how
the shrewd Augustus was shifting

the object of Roman worship
from the gods

to himself and his own family.

SPEAKS IN ITALIAN

So, what are the images on it?

And Augustus's family connection
to the gods

is even more explicit
in another scene.

What did Augustus want the people
who saw this shrine to believe?

By putting images of his deified
ancestors on shrines all over Rome,

and encouraging sacrifices to them,

Augustus was making
a bold statement.

Augustus was inviting
all ordinary Romans

to take part in the creation
of a new imperial mythology.

The city of Rome was being
indelibly stamped

with the divine claims
of one family, one ruler.

And Augustus set the tone
for the emperors who came after him.

During his life, he was the sole
religious authority in Rome.

And on his death, by vote of the
Senate, he too was declared a god.

The Forum is a living testament
to Augustus's precedent.

Temples to the deified emperors
would soon dominate
this sacred space.

So here is the temple to
the Emperor Antoninus Pius.

And here, these columns were
the temple to the emperors
Vespasian and Titus.

Now, Vespasian,
who was a bluff soldier,

kept a sense of humour
about divinity.

When he lay on his deathbed,
he joked,

"I think I'm about to become a god."

But other emperors lacked
his sense of detachment.

The demented emperor Caligula
cavorted as the goddess Venus

in a gorgeous bejewelled dress.

The emperor Hadrian took all of it
a step further

when he deified his young gay lover.

And as for Nero, he built a 120ft
statue of himself as the sun god,

right here in the centre of Rome.

But it was the imperial cult
and its demands that provoked
a minor challenge

to Roman religion,
with world-shattering consequences.

A new generation of foreign sects

were starting to gain popularity
in the city.

And one in particular
showed resistance

to this worship of emperors.

That cult was, of course,
Christianity.

And 300 years after its emergence,

it would entirely reshape
the city of Rome.

The pagan temples would be
converted into churches,

leaving the Roman gods
to crumble into dust.

But when it first arrived in Rome,
in the first century AD,

Christianity looked
less like a force to be feared

and more like a sect of cranks
with peculiar

and preposterous beliefs,
worthy of mockery.

And there's a glimpse of just how
unthreatening the pagan Romans

initially thought
the Christians were

in a rare piece of ancient graffiti,

uncovered by archaeologists
in the 19th century.

So here it is.

It's very small
and it's very hard to see,

and I find it absolutely
fascinating.

What we have here is a human figure
being crucified on the cross.

What's bizarre about it is that
the person being crucified

has the head of a donkey.

There's a figure, apparently
worshipping beside the cross,

hand raised, possibly a soldier,

and, underneath, it says,
"Alexamenos worships his God."

Now what's remarkable about this
is it's the first ever

representation
of the Crucifixion in history.

What's interesting
is that it's clearly

not by a Christian at all,
but by a pagan Roman.

The graffiti dates from between
the first and third centuries AD

and, at that time, the symbol
of the cross wasn't something

the Christians were proud of.

Crucifixion was a shameful death -
the method of execution

for the lowest criminals,
like showing someone today with

a noose round their neck,
and, in the earliest Christian art,

the cross doesn't appear at all,
so this pagan graffiti artist

is deliberately mocking
and insulting Christian worshippers.

To show Jesus with a donkey's head
is the cruellest cut of all.

And donkey worship
wasn't the only tittle-tattle

circulating about the Christians.

They were also rumoured
to practise magic,

indulge in ritual cannibalism
and even incest.

It was all good gossip
for the Roman on the street,

but within 200 years,
rumour had turned to concern.

As Rome's elite realised,
this new sect was persistent

and potentially dangerous.

The Christians were well-organised,
they recruited thousands

of new followers, but, worst of all,
they refused to take part

in the Roman state religion,

claiming that they worshipped
only one God.

They were beginning to look
less like a bunch of harmless

and superstitious eccentrics
and more like a movement

of defiant subversives
who could no longer be controlled.

The Roman elite had in the past
tolerated foreign gods,

but they were always clear that
whatever people's private beliefs,

public loyalty to Roman religion
came first.

After all, the fortunes of the city

were at the mercy
of the pagan gods -

snub them and the consequences
could be catastrophic.

So if a group like the Christians
failed to pay due respect,

how would the gods react?

The fate of the city
and its Empire hung in the balance.

And in the third century, it seemed
as if their fears were justified.

The Roman Empire
was beset by invasion,

civil war and economic depression.

It was on the verge of collapse...

..until the reign
of a new emperor - Diocletian.

He was a superb general,
who restored order by conquest,

reform and restoration
of the old gods...

..but one sect resisted.

And when Diocletian's palace
burned down

and the army's sacrificial
portents looked bleak,

the Christians were blamed for
failing to honour the Roman gods.

Diocletian decided to solve
the problem by force. In 304 AD,

he ordered every citizen of
the Empire to sacrifice publicly

to the Roman gods,
and if the Christians refused,

they would be executed.

It was a strategy designed to
drive the Christians into the open.

Yet, despite the threats,
they remained defiant.

Rome's senators were baffled.

Why would anyone risk their lives
for this upstart cult

whose founder died a criminal's
death in a Roman outpost,

when the pagan gods had delivered
the riches of Empire?

Yet, still, pagan Romans
were choosing to convert,

and here in the suburbs of Rome,

there's a fascinating clue
as to why.

This is the Catacomb of Priscilla
where Christians were buried

in the first centuries
of the church,

and it's one of the few
places in Rome

that they left their mark -

the walls are covered by
their paintings.

And there's one that gives an
insight into just why pagan Romans

were choosing to face execution
for this new Christian God.

So here it is.

This is a biblical scene from
the Old Testament Book of Daniel

and it tells the story of
these three Jewish characters

who were in exile in Babylon
from Israel.

They refused to pray

to the image of the king of Babylon,
Nebuchadnezzar and, as a result,

they were sentenced, as you can see,

to die horribly
in this fiery furnace.

Parallels for Christians facing
persecution in Rome were clear,

but there's a twist to the biblical
story which gives this image

another dimension.

What's surprising about this
is that if you look closely,

these characters are praying,
but they're not burning.

The Book of Daniel
says that they were able to walk

unscathed among the flames
and emerge entirely unharmed.

Their God had saved them.

Now, for Christians, this had
another layer of meaning.

The Christian God would not only
save Christians from persecution,

he would also save them
from death itself.

Christianity offered eternal life.

And this belief in eternity
had huge appeal in this pagan city.

For your average Roman,
life expectancy was only 29

and daily life was hard.

For the poor, the slaves,

the Pagan Romans at the bottom of
the pile, this Christian idea of

a new life after death offered hope

amidst the grind
of unrelenting poverty.

The Roman gods may help you
conquer an Empire,

but they didn't offer immortality.

It was a masterstroke.

Rome's leaders might be worshipping
its pantheon of pagan gods

but some of its people
were starting to look elsewhere.

Ancient Rome has always been
a symbol of secular power,

but you can't understand
the might of this city without also

grasping the sacred beliefs
of the Romans themselves.

Right through its history,

Rome's greatness was inextricably
linked to its sacred mission.

For its first thousand years,
Rome's palaces and temples expressed

one thing - this was a holy city,

blessed by the gods to rule
the world.

But all that was to change.

A new god was about to take Rome.

Next time, Rome's transformation
from pagan heartland

to the capital of Christendom,

as religious revolution
hits the holy city.
