Ambition... Conquest
Lost... Murder...
and the power of unrivaled technology.
These are the cornerstones in the
foundation of the Roman Empire.
They were driven by a kind of collective
cultural ego. Roman's colossal
building projects:
Stadiums...
Palaces...
Roads...
Aquaducts...
span 3 continents and
unleash the power and promise of the
world's most advanced civilizations.
These structures became symbols of
that idea of Rome.
But while Romans
dominated the landscape with their
massive feats of construction,
they were ultimately powerless to
prevent their own self-destruction.
March 15th, 44 BC.
The most powerful man in the world
lay lifeless on the floor of the Roman
Senate.
As a General he nearly doubled
the size of the Roman Empire. As a
Politician he engineered a stunning
rise to power but now this
battled-scarred warrior had been
slayed in Rome and by Romans.
His name was Gaius Julius Caesar.
Caesar's rise to power was predicated
on him wanting to have the best
standing in the Roman State. He seemed
to want too much power for himself.
He didn't want to share power with others
and this is what led directly to his
assassination.
Decades earlier as an
ambitious young general, Caesar had
recognized that the road to glory in
Rome began on battlefields far from it.
His thirst for military conquest would
spawn construction of one of Rome's most
intimidating feats of engineering.
55 BC
Julius Caesar is leading 8 Roman legions.
A total of 40,000 men north through Gaul.
A Roman Providence encompassing modern
France, Belgium and Switzerland.
He wants to go to Germania, to Germany,
and cross the Rhine
because no Roman Commander has yet done so.
He wants to be as great a conqueror as
Alexander the Great. Go beyond
what is known.
The Rhine River
lies on the edge of what is known.
For centuries
it has been a buffer protecting
Germanic tribes from Roman
expansion. No previous army could cross
it with the might needed for conquest.
But Caesar is unlike any previous warrior.
He could have gone by boat but what is
that for Julius Caesar to go by boat.
A row boat? you know Are you going to put 8
legions on a row boat & go across?
No, man! They need to march across.
They need to be on horseback.
From the engineering point of view, the
difficulties of constructing a bridge
over such a river are enormous in relationship
to the depth of the water and the
forceful current. If you bare in mind
that this had to be done in a short
period of time due to military needs.
The works is actually truly exceptional.
The bridge would need to be four football
fields long and sustain 40,000 soldiers.
Despite the Rhine's width, depth
and strong currents,
Julius Caeser is determined to succeed.
To cross a river that size with a bridge
is something which plays well with an
audience back at home but of course it's something that
plays extremely well with the audience
standing on the other side of (across) the river
who are going to be
awestruck when they see this happening.
With the speed and efficiency of a well
oiled machine, Caesar's soldiers
methodically transformed local timber into an
expanding bridge.
With every hour an
engineering miracle inches closer
to the Rhine's elusive northern bank.
It's almost as if a spaceship, nowadays,
the size, let's say, of half of Manhattan
capable of some magnetic device that
will lift buildings up in the air.
That would be a pretty frightening thing.
Something that we couldn't really grasp
at all.
The foundation of the bridge was
a series of wooden piles driven into
the bedrock of the river.
Each pile was a foot and a half thick.
Towards the middle of the bridge,
they had to be up to 30 feet tall
to reach from the surface to the bottom.
By driven the piles in diagonally,
Caesar's engineers had added
extra stability to the bridge.
When they drove the pilings in at an angle
and connected them, in many ways they are
doing what carpenters do when they are
building a sawhorse. With the legs angled
it utilizes forces to keep from being
pushed over making it a stable work space.
The sloping power offers a lot more
strength against the force of
the river and the flooding of the river
but it's much more difficult to drive
them into the riverbed
than it is to drive a vertical pile.
They would have had to work very carefully
with wooden frames to push them into
the riverbed. On the upstream side, the
piles leaned in the direction of the
current. 40 feet downstream the
corresponding piles leaned against the
current. Each set of piles were joined
by a long connecting beam two feet thick.
Lengths of timber were then laid against the
beams and the surface was finished
with tightly wrapped bundles of sticks.
The design of the bridge was innovative
but what made this engineering feat even
more astounding is the speed in which it
was built. Just 10 days after ordering
it's construction Caesar marched across
his bridge and toward his destiny. If we
tried to do that today, we would never
be able to build something like that in so
few days with that kind of technology.
We could match that feat today if we had
thousands of loyal, sweating soldiers
totally dedicated to Caesar and the
objective of crossing the Rhine River to
terrorize the Germans. Caesar had
estimated the size of the Germanic forces
at 430,000. More than 10 times the size
of his army. When the Germans saw the
Romans legions rolling over the Rhine,
they quickly fled to higher ground.
For the next 18 days, Caesar freely
explored the territory north of the Rhine
encountering no resistance. Then he
crossed back over his bridge & dismantled
it having made an unmistakeable point.
It is symbolic of this that Rome can go
anywhere. And to take it even further
Julius Caesar can go anywhere. Caesar's
bridge was an early indication of his
single-minded ambition
propelled him to unparallel power
but would also prove to be his downfall.
A decade later that ambition would
When he was declared Rome's first
dictator for life at the age of 55
in 44 BC whispers of assassination began
to whisper through the halls of the
Roman senate. He makes certain moves
that suggest that he might want to be
worshiped as a god that his ambition
goes so far beyond the limits of what the
