NARRATOR: Nothing represents the mysteries of ancient Egypt
more than the Great Sphinx.
How did the Egyptians build this crouching lion,
human-headed creature?
MAN: This is the largest statue
ever built in ancient Egypt.
NARRATOR: Who built it, and why?
MAN: When it was in its heyday,
it was a very brightly painted image,
painted in comic book colors.
NARRATOR: The riddles of the Sphinx have puzzled
all who have laid eyes on it,
from emperors to presidents.
Now, solving those riddles has taken on a new urgency,
for after more than 4,000 years with only pyramids as neighbors,
today the Sphinx stares out at a fast food restaurant.
Traffic, tourism and construction
are trembling it apart.
The Sphinx is almost in downtown Cairo.
NARRATOR: It' urban assault.
Before it' of scientists and builders
are tackling the age-old riddles of the Sphinx.
MAN: It'
NARRATOR: They' in the world of ancient Egypt--
a world of pharaohs and pyramids...
animal gods and mummies...
sun worship and human sacrifice.
Will the eternal sands of Egypt finally give up the secrets
of this human-headed lion?

Major funding for NOVA is provide NARRATOR: Giant paws longer than a city bus stretch out before it.
A whipping tail wraps around its back.
And its enormous body-- about the weight of 50 jumbo jets--
is on haunches poised to pounce.
But this lion has a human head as big as a house,
for this is the Great Sphinx.
At nearly 240 feet long, almost the length of a football field,
and almost 70 feet tall, the height of the White House,
the Sphinx is the largest statue in all of Egypt,
a land renowned for its oversized monuments.
It' Sphinx and the Great Pyramids,
where building big really booms.
Around 2500 B.C.-- more than 4,000 years ago--
the Giza plateau is a desolate landscape.
A visionary pharaoh named Khufu constructs the Great Pyramid.
He' and then his son'
who build two more pyramids.
Designed as giant tombs
to ensure the kings' passage to the afterlife,
the pyramids and their surrounding temples
transform an area of the Giza plateau
into a vast city of the dead.
Pharaoh Khufu' the most famous gravestone
on Earth.
Khufu' probably stood here
and looked out over the panorama behind me
and maybe foresaw three generations of building here
because of the excellent conditions
for carving giant statues and for building pyramids and tombs.
NARRATOR: Khufu and his sons launch a golden age of Egypt
known as the Old Kingdom.
But while the classic pyramid can be traced back
to earlier forms, like the Stepped Pyramid of Saqqara,
the Great Sphinx appears out of nowhere,
unprecedented in size and form.
And while inscriptions inside the pyramids
reveal who built them,
there are no such clues about the origins of the Sphinx.
What is this crouching lion, human-headed beast?
How did the Egyptians build this wonder of the ancient world?
Whose face is this staring out across the millennia?
Now two teams tackle these age-old mysteries of the Sphinx.
One team of scientists investigates the geology,
history and archaeology of ancient Egypt.
Many people who try to look at the Sphinx,
they look at it by itself.
But you have to look at all the architecture,
archaeology, art, inscriptions.
You have to look at all of this
to explain the function of the Sphinx.
NARRATOR: Another team of stone-carvers will build scaled-down replicas
of the Sphinx and its missing nose
to shed light on how the ancients carved
this wonder of the world.
RICK BROWN: It'
in all of Egypt, most of the stone'
with just pounding for thousands and thousands of hours.
NARRATOR: The race is on to unlock the riddles of the Sphinx.
There have been thousands of sphinxes throughout history.
But this sphinx, the Great Sphinx,
is one of the very first
and is by far the largest ever built.
LEHNER: This was an age of experimentation.
The Sphinx is an experiment.
It was something new, something highly unusual.
NARRATOR: So where did the idea of putting a human head
on a lion'
Archaeologist GuÃ¼nter Dreyer is searching the desert of Abydos,
about 300 miles south of Giza and the Pyramids.
Dreyer is traveling back past Khufu and the Old Kingdom
to the very dawn of Egyptian civilization--
3000 B.C., 500 years before the Sphinx.
Like Giza, Abydos is also a city of the dead,
but without pyramids.
Here, Egypt' are buried
beneath the desert sands in a complex of mud-brick tombs.
(speaking Arabic)
Today Dreyer is investigating one of those tombs.
The tomb consists of three huge chambers
underneath that mound over there.
And in front of it,
there are three rows of subsidiary burials--
altogether 35.
NARRATOR: The main chamber was plundered in ancient times
and the royal bodies stolen,
but inscriptions found inside reveal a name--
Pharaoh Aha, the very first king of Egypt'
As pharaoh, Aha wielded absolute power.
The Abydos excavation reveals evidence of human sacrifice.
The skeletons of 35 healthy adults,
most under the age of 20, all part of a mass burial.
DREYER: Even at that remote time, that is not a natural age of death.
And so we may conclude they were killed to follow the king
in his afterlife, to serve him there in eternity.
NARRATOR: The pharaoh and his worldly goods are buried
at one end of the complex,
followed by the 35 victims of human sacrifice
in smaller tombs.
And in the last tomb are even more bones,
but these are not human.
For identification, they were compared with modern skeletons.
By sifting, we found a lot of animal bones,
especially bones of lions.
That was quite a surprise.
NARRATOR: Several lions died and were buried
at the same time as the young adults,
evidence that they too were sacrificed.
But why were these lions entombed along with the pharaoh?
The king identifies himself with the lion to show his power,
to express his power.
NARRATOR: Dreyer' that Egypt'
wielded enormous power...
enough to command the ritual slaughter of dozens of people.
And the lion sacrifices provide the first clue to the meaning
of the Sphinx'
lions symbolize the power of the pharaoh.
But the Sphinx is more than just a lion.
It'
Ancient Egyptians depict their gods as part animal, part human.
But usually those gods have animal heads and human bodies.
The Sphinx is just the opposite.
LEHNER: When you put the human head on the lion body,
you have all the strength and power of the lion.
And you have the human head,
which is a symbol of intelligence and control.
And so it is an image of power under control.
NARRATOR: But whose power and control?
LEHNER: The human head is actually wearing a scarf
called the nemes; it'
And only the pharaohs wore the nemes headdress.
NARRATOR: So the Sphinx is both a god and a pharaoh.
(speaking Arabic)
And when it came to symbolizing the power of the pharaoh,
the bigger, the better.
Over the next 500 years,
the pharaohs' more and more massive,
from underground burial chambers
to aboveground tombs,
and from stepped pyramids to the Great Pyramids of Giza.
But while the form and size of royal tombs evolve slowly,
the Great Sphinx has no precedent.
LEHNER: It was the first time
in the history of Egypt that they created sculpture
at this scale.
NARRATOR: So, how was the Sphinx created?
Looking at its paws, it appears to be built
with thousands of blocks.
Was it constructed like the pyramids,
by stacking blocks of stone?
But a closer look reveals that its upper body and head
are carved out of one huge rock.
Does that mean it was carved like Mount Rushmore?
Clues lie in the stone of the Sphinx and the rock around it.
Amazingly, nobody had ever investigated its stones
in any detail...
Until Mark Lehner 30 years ago.
Today he' leading Egyptologists.
When I first came to Egypt,
the best maps that existed of the Sphinx
were simply the outline.
NARRATOR: If you' how the Sphinx was built,
the existing drawings were about as useful
as if you were trying to build a 50-story skyscraper
using just a satellite snapshot of its roof.
That' about the Sphinx.
To unlock its secrets,
someone needed to take a much closer look.
LEHNER: So I spent five years here mapping every stone to scale.
This was my office.
And I would take my breaks here and have a stale cheese sandwich
and a cup of Nescafé.
NARRATOR: Lehner' an intimate knowledge
of the Sphinx, its stone and the Giza plateau.
To begin with, the Sphinx is made of limestone.
Close inspection of the limestone
reveals how it was formed.
LEHNER: You see a pattern that looks kind of like a brain coral,
or almost like a sponge.
All the limestone at Giza,
including the body of the Sphinx,
was once the floor of a sea, it was a seabed.
So you have frozen into the stone
various elements of seafloor life.
NARRATOR: Millions of years ago, the Giza plateau was underwater.
Sea creatures and plants died, falling to the bottom.
Over time, their remains were compressed to form limestone.
But not all limestone is created equal.
Some limestone is formed from the soft sea bottom
and some from hard coral reefs.
Together they form a kind of layer cake
of hard and soft limestone.
LEHNER: The Sphinx is composed
out of several different limestone layers.
So it' the Sphinx out of a layer cake.
And there are gooey layers of soft frosting,
and then there are intervening harder layers.
NARRATOR: The harder layers of rock have held up better
than the softer layers.
Today it looks a lot different from when it was first built.
Its original smooth surface has been eaten away
by over 4,000 years of wind, water and sand.
LEHNER: Here on the right side of the Sphinx chest,
we can see how weathering has put
the softer layers into deep recesses,
while the harder layers protrude.
NARRATOR: To Lehner, this weathering pattern
is another important clue to how the Sphinx was built.
Recent restorations obscure this pattern...
but photographs from the 1920s clearly show it...
on both the body of the Sphinx...
and on the side of what is known as the "Sphinx ditch."
The pattern acts like a fingerprint.
And when Lehner compares the Sphinx'
with the side of the Sphinx ditch, it'
We are certain that these are the same layers of natural rock
that form the south side of the Sphinx ditch.
NARRATOR: Lehner identifies more of that rock directly in front
of the Sphinx' in the ruins of a building
known as the Sphinx Temple.
There, on the huge stone blocks
that were once the walls of the Sphinx Temple,
he discovers those same familiar layers of hard and soft stone
that he finds on the Sphinx.
LEHNER: Because you can see the layers
runs continuously from one block to another
through many of the blocks forming the temple walls.
Here is one geological layer,
then this yellow band is a softer geological layer.
NARRATOR: But what does the similarity of the rock in the Sphinx,
ditch and temple tell Lehner about how the Sphinx was built?
LEHNER: The Egyptians quarried a horseshoe-shaped ditch,
leaving a core that left a big block from which they carved
the Sphinx itself.
They moved the stone, sometimes in blocks of a hundred tons,
down to the lower terrace for fabricating the walls
of the Sphinx Temple.
NARRATOR: So the starting point for the Sphinx must have been
a huge rock sticking out of the surface of the Giza plateau.
Workers cut a trench around it,
quarrying the stone out from the ditch in huge blocks.
They hauled off those blocks to build the nearby Sphinx Temple.
Then, sculptors carved the giant rock
remaining in the center into the shape of the Sphinx.
The Sphinx was carved right out of the natural mother rock
of the Giza plateau.
NARRATOR: But knowing that it' right out of the earth
is only half the mystery.
How did they actually do it?
Sculpting a human-headed lion out of 20,000 tons of limestone
is no small matter.
So, Fathi, we need to get two types of rock.
NARRATOR: To investigate the challenges faced by the ancient sculptors,
archaeologist Richard Redding and Fathi Mohamed,
a stonemason who has worked at Giza since he was a boy,
team up to carve a mini-Sphinx.
So, let' we can find here.
NARRATOR: They search for limestone that'
in the Sphinx'
REDDING: I think we'
What you can see is this one' nice and strong.
It' Okay.
NARRATOR: They find just the right stone in a nearby quarry.
It'
And hard... maybe too hard.
(translated): Mr. Richard!
My tools will be ruined.
NARRATOR: Fathi is worried that the hard rock will ruin his tools.
FATHI MOHAMED (translated): My tool' but the rock bent it.
The rock is very hard.
NARRATOR: If Fathi is having such a difficult time
using modern steel tools,
how did the ancient Egyptians carve the Sphinx
with more primitive tools?
The answer will come half a world away.
LEHNER: Hey, Rick, New England in the fall is a far cry
from Egypt in the desert.
NARRATOR: Mark Lehner has come to consult with Rick Brown,
a specialist in ancient tools.
Based on actual copper tools found at Giza
and tomb scenes depicting stonecutters at work,
Brown gathers everything an ancient Egyptian would have had
to carve the Great Sphinx.
LEHNER: Rick and I got together and looked at all the evidence
we have from the tomb scenes, from actual tools that we found,
and based on all this evidence, Rick has put together
the rudiments of the toolkit that the Sphinx builders
would have used.
BROWN: So we have copper chisels,
two-handed pounder, and there'
NARRATOR: To really understand the challenge
of using these tools for carving,
Lehner and Brown begin by making them,
starting with a copper chisel.
Even a little bit more right now.
We just need to get some good heat.
NARRATOR: Working long before the invention of harder bronze
or iron,
the Sphinx sculptors had to make do with softer copper.
BROWN: This is what they would have done in Egypt.
They take a blank of copper, we'
and we' this into a chisel.
NARRATOR: The pure copper starts out a metal gray,
and as it heats it turns red.
LEHNER: So you want that piece of copper red hot.
BROWN: Yeah, when I get color in the copper, we'
Okay, it looks good.
Ooh, we got it red hot.
NARRATOR: The heat softens the copper into a more pliable material
that can be pounded into shape.
BROWN: You know, this process is so basic.
What they were doing was they were using a hard material
to fashion and shape a softer material.
NARRATOR: But as the soft copper cools, it hardens again.
I want to go back to the fire
because I can actually break the metal,
so let'
NARRATOR: Already these ancient tools reveal
there' Sphinx than just carving.
LEHNER: Charcoal was a crucial ingredient
of making these monuments at Giza.
They must have been trucking wood in
and feeding these fires all day long, all year round,
just to make the tools to make the monument.
Now I want to have it flatten down this time.
NARRATOR: The heating/pounding cycle is repeated over and over
until the shape is just right.
I want it to be straight along the axis like this,
because if it' turning a little bit,
that means it' to last as long.
That'
LEHNER: They must have amassed more copper
for building the Great Pyramid and the Sphinx
than just about any place in the world
in the third millennium B.C.
I mean, it just must have been a huge cost in copper.
NARRATOR: But the copper chisel was the high-tech finishing tool
of the Old Kingdom.
The real grunt work was achieved
with something much more basic-- stone hammers.
BROWN: Mark, if you look at this photograph of the tomb of Ti,
there is a stone carver
using a tool like this,
and this is what I'
you have to really look carefully at these drawings
because they give a lot of information.
NARRATOR: Based on this 4,000-year-old tomb painting,
Brown and Lehner make their own hammers today.
I want to use a harder stone against a softer stone.
LEHNER: So you' to make a stone tool.
There' of pounding going on.
NARRATOR: The grooves and lashing transform a simple stone
into an effective hammer.
LEHNER: It'
They probably did it as quickly as tying a shoe.
The thing about this is I think the critical thing
is it gives you a lot more action.
BROWN: He can work like that for many, many hours
and not wear himself out.
NARRATOR: Now Lehner and Brown will put the tools to the test.
They' carve the feature of the Sphinx
that' absent-- the nose.
There are stories that it was shot off by Napoleon'
using it for target practice.
(gunshots)
But they turn out to be false.
LEHNER: About 300 years before Napoleon,
an Arab historian already mentions that the nose is gone.
I think there'
that it was snapped off intentionally.
There' down the bridge
and there' in the Sphinx'
I think somebody might have pounded these metal wedges
and then snapped it off to the south.
NARRATOR: While the original nose is lost forever,
today Lehner and Brown,
with just stone hammers and copper chisels,
will carve a new one.
LEHNER: Let'
BROWN: I'
NARRATOR: Out of this six-foot chunk of hard limestone
they will attempt to carve a nose
nearly half the size of the original.
We' starting with tools like this?
Was that my idea?
Yes.
NARRATOR: They dive in...
and quickly discover that hard stone is much more effective
than the soft copper in these early stages.
That' that the pounder,
even though it seems primitive, is actually quite effective.
NARRATOR: But even with reinforcements
and after hours of pounding, they'
Will Lehner and Brown really be able to carve a nose
with these ancient tools?
Zahi Hawass,
secretary general of Egypt' Supreme Council of Antiquities,
is the official guardian of the Sphinx.
He has searched this colossal cat from head to toe
for clues to how it was built.
He knows from the geology that it was carved
right out of the earth.
So why does the bottom appear to be built out of stone blocks,
like the Pyramids?
Hawass investigates the size and style of the blocks for answers.
If you look at the two paws of the Sphinx,
this is a typical small stone
that the Romans in 30 B.C. came and they did add this
to the Sphinx.
NARRATOR: Just between the Sphinx'
Zahi Hawass finds blocks from four different periods.
This is 30 B.C., 1550 B.C., and this is 2600 B.C.
NARRATOR: Hawass concludes that Egyptians, Greeks and Romans
have been covering the Sphinx in blocks
for thousands of years.
But why?
The answer can be found in a deadly hidden force
attacking the limestone of the body of the Sphinx
and the surrounding ditch.
LEHNER: All of this was once the floor of a sea.
It was a seabed 50 million years ago.
So it'
NARRATOR: When groundwater rises, it seeps through the rock,
drawing the salt to the surface,
where it crystallizes and expands.
The results are disastrous for the Sphinx.
I hate to do this,
but it' all the time
on this wall next to the Sphinx.
The flakes fall and crumble.
This is what was happening to the Sphinx body.
It' in literally Sphinx dust.
NARRATOR: Amazingly, from the day it was built,
the body of the Sphinx has been turning to dust.
The blocks put there by Egyptians, Greeks and Romans
were to protect and conceal its deteriorating body,
especially the more vulnerable parts carved
from soft limestone.
But while the soft stone is bad news for the Sphinx,
it' for sculptor Fathi
because it' to work with
as he carves his mini-Sphinx.
(translated): Now I am working on the foot of the back leg.
I am sculpting the paw and the thigh.
NARRATOR: He makes quick progress
because the stone is so soft.
But now comes the hard part.
Fathi reluctantly returns to the head,
which, like the original Sphinx,
is made of much harder limestone.
(chisel ringing as it strikes)
Striking this harder rock, his chisel is far less effective,
and progress slows dramatically,
even with the advantage of his modern steel tools.
So how are Lehner and Brown progressing back in New England
with their ancient copper tools?
(banging)
After days of work, their copper chisels and stone pounders
are barely making a dent.
At this pace, it' they'
out of this rock anytime soon...
Unless Brown and his team resort to taking some shortcuts.
Well, I guess you caught us.
We worked on the stone for a long time using Egyptian tools
and then decided that we' to the modern tools.
It'
NARRATOR: Granted, the power tools are a lot faster
than the ancient tools, but surprisingly,
the basic carving process hasn'
since ancient times.
BROWN: What the Egyptians would do is they would make these channels,
these parallel channels.
Then you come back with a flat chisel
and blast out all that material in between.
NARRATOR: But while Brown' chisel has a carbide tip
hammering at 2,000 hits per minute,
the copper chisel the ancient Egyptians would have used
lasts only a few dozen strikes.
BROWN: You see after I'
about the equivalent of maybe ten centimeters,
my tool' almost useless.
BROWN: Each time the tool gets dull,
we have to come back and reheat.
When we reheat, it softens the metal
and then we can re-shapen it.
NARRATOR: Brown is wearing down tools at an extraordinary rate.
For efficiency, he moves his forge closer to the carving.
BROWN: We brought our forge down here
closer to the stone because we'
blowing through the copper chisels so fast
it gives us the opportunity to use them, dull them,
sharpen them and go right back to work,
which is probably like they did in Egyptian times.
NARRATOR: Brown is discovering it'
a lot of time and a great number of copper tools,
and his stone shows little evidence of progress.
It' of rock will ever be
a finished nose, even one nearly half the size
of what was originally on the Sphinx.
It' carving the Great Sphinx
as big as a football field.
Clearly only a pharaoh could pull this off.
The question is, which one?
The location of the Sphinx undoubtedly links it
to the pyramids.
Whoever built the pyramids likely built the Sphinx.
The problem is, the Sphinx appears to sit right between
two pyramids, built by two different pharaohs.
The first and largest pyramid was built by Pharaoh Khufu,
who reigned around 2500 B.C.
His son, Khafre, built the second,
slightly smaller pyramid.
Rainer Stadelmann, a leading Egyptologist,
believes the head of the Sphinx
represents the pharaoh who built it.
So Stadelmann compares the face of the Sphinx
to the face of the pharaohs
in hopes of revealing its true identity.
STADELMANN: I remember when the statue was still standing...
NARRATOR: He turns to the only undisputed portrait of Khufu ever found,
a small ivory statuette.
STADELMANN: This piece is something extraordinary.
And I am so excited that you can open it.
NARRATOR: It has not been removed
from its glass home in the Cairo Museum for 30 years.
It is something I would not have believed
that we are allowed to do this.
And this statue is a real masterpiece.
STADELMANN: Everything is very finely sculptured,
so detailed that one can compare the statue
with the enormous Sphinx statue.
The face is, for me, the same face as the Sphinx,
a square face, a little bit bitter mouth.
The eyes are protruding.
NARRATOR: But there' subjective clue.
Unlike his son Khafre, the builder of the second pyramid,
Khufu does not have a beard.
STADELMANN: The statue does not wear a beard.
So I am quite sure the Sphinx,
which has no beard at all, is a picture of Khufu.
NARRATOR: But Mark Lehner finds evidence
that the Sphinx originally had a beard.
And he believes the face of the Sphinx is the son, Khafre.
LEHNER: An original beard would explain this very enigmatic bump
on the Sphinx'
It starts right about here and it'
to support the long beard.
NARRATOR: The debate rages on.
And I think the beard was original.
NARRATOR: The father, Khufu, or his son, Khafre?
We don'
NARRATOR: The Sphinx' cannot be resolved
by facial features alone.
For Fathi, sculpting the mini-Sphinx,
a solution is needed.
With the body almost completed,
Fathi returns to the harder stone for the head
and must decide: beard or no beard?
(translated): I think the Sphinx used to have a beard
because all of the pharaonic statues
in the form of the Sphinx had beards,
like those of Hatshepsut and those of Ramesses,
so the Sphinx must have had a similar beard.
NARRATOR: It' as Fathi places the head
on the body of his mini-Sphinx.
But the face is not that of Pharaoh Khufu or Khafre.
It turns out Fathi has ignored the advice of all the experts
and followed in the tradition of the pharaohs.
Fathi' a striking resemblance...
to Fathi.
For more than 4,000 years,
this curious creature has captured the imagination
of kings and emperors, poets and painters...
and presidents.
Today the Sphinx is the face of Egypt
and icon of its age-old mysteries.
But what did it mean to the ancient Egyptians?
The Old Kingdom collapses
and the Giza plateau becomes an abandoned cemetery,
the Sphinx and Pyramids neglected.
Nearly a thousand years pass
and the power of the pharaohs rises again
in a period called the New Kingdom,
beginning about 1500 B.C.
But centuries of wind and water have eroded
the Sphinx'
and desert sands have swallowed the Sphinx up to its neck.
What happens next is written in hieroglyphs
on a gigantic 15-ton granite stela,
perched between its paws.
The inscription tells of a hero who rescues the Sphinx.
A young prince clears away the sands
and the Sphinx rewards him by making him king.
His name is Thutmosis.
HAWASS: Who was the first restorater on earth?
I can say Thutmose IV.
He ordered his people to build these two huge mud-brick walls
to protect the Sphinx from sand.
NARRATOR: Opposite the Sphinx' left haunch
and above the Sphinx ditch are remnants of a mud brick wall.
Some of its bricks are stamped with the name of Thutmosis.
Originally coated in plaster,
the wall stood nearly 30 feet tall.
And to restore the Sphinx' weathered body,
Thutmosis placed large blocks of stone on its paws.
Look at these stones.
That is the big stones that were added in the New Kingdom.
NARRATOR: And this stela also reveals a clue
to what the Sphinx meant to New Kingdom Egyptians.
KASIA SZPAKOWSKA: When the kings wanted to record something
that they wanted to last forever,
they would write in stone.
And they would write on very large stelae such as this one
in hieroglyphs.
NARRATOR: Kasia Szpakowska translates two key hieroglyphs.
SZPAKOWSKA: You can see there' that looks like a bird there.
That' of the falcon.
That'
NARRATOR: Horus, depicted as a falcon,
is one of the oldest and most important deities
in the Egyptian pantheon.
Egyptians believed that the pharaoh was Horus incarnate.
SZPAKOWSKA: And just below is the akhet, the horizon,
with the two mountains on the side
and the sun disk in between.
NARRATOR: When the falcon and akhet hieroglyphs are combined,
they form "Horus on the Horizon,"
the name of an Egyptian god who guards the entrance
to the afterlife.
This is the identity of the Sphinx in the New Kingdom.
To ancient Egyptians,
the horizon was the entrance to the afterlife.
Just as the sun sets over the horizon and rises the next day,
they too believed they could be reborn.
As the guardian to the afterlife,
the Sphinx was crucial to that process.
Thutmosis, by clearing away the sands,
was not just saving the Sphinx, he was saving a god.
And he does more.
Close inspection of the face of the Sphinx
reveals traces of blue paint still clinging to its ear.
The evidence suggests Thutmosis gives the Sphinx
a New Kingdom monumental makeover.
LEHNER: We' as this beige-colored monument
out in the desert.
But when it was in its heyday, reborn in the New Kingdom,
it was a very brightly painted image,
painted in comic book colors.
The face was probably red.
It' was painted yellow and blue.
And this painting of the Sphinx was something that,
for the Egyptians, probably brought it to life.
NARRATOR: The Great Sphinx, revered as a god,
guarding the entrance to the afterlife;
a statue of its savior, Thutmosis,
overlooking a royal chapel nestled between its paws;
protected from the howling winds and sand
by a tall retaining wall
and brought to life in vibrant color.
But the New Kingdom, when Thutmosis ruled,
was over a thousand years after the building of the Sphinx.
To him, the Sphinx and whoever built it
were already ancient history.
So, what did the Sphinx mean to its original builder--
either the father, Pharaoh Khufu,
or his son, Khafre?
Mark Lehner returns to the Sphinx Temple
to solve the final mystery.
The ruins of the temple sit just ten yards
in front of the paws of the Sphinx.
We know from other temples...
NARRATOR: There, Lehner finds a series of mysterious pillars.
They look a little bit like Stonehenge.
NARRATOR: There are 24 of these pillars.
Lehner believes they are linked to the 24 hours of the day.
LEHNER: It seems to have been
a very early massive temple to the sun.
NARRATOR: This notion is reinforced by two inner sanctuaries
at opposite ends of the temple.
This niche or sanctuary is symmetrical
with another niche on the west.
So, the two niches define the temple axis,
probably for the rising sun on the east
and for the setting sun on the west.
NARRATOR: During the spring and fall equinox,
the two days of the year when day and night
are in perfect balance, the sun forms a line
between the east and west sanctuaries of the temple.
As the sun continues its path toward the horizon,
it passes over the shoulder of the Sphinx
and beyond to one of the Great Pyramids.
LEHNER: These two niches line up to the south side
of the second pyramid
at a point striking right over the Sphinx'
And this is where the sun sets at the equinoxes.
NARRATOR: When it sets at those special times of the year,
the sun connects the Sphinx Temple to the pyramid of Khafre.
And because the Sphinx Temple and the Sphinx
were part of the same engineering project,
they must have been built by the same pharaoh.
LEHNER: It' astronomical alignment,
that'
that ties this temple and the Sphinx to the reign of Khafre,
the builder of the second pyramid.
NARRATOR: The sun also played a central role in Old Kingdom religion.
Ancient Egyptian art depicts a god supporting the sun disk
as it travels over the horizon to the afterlife.
He was one of Egypt' gods, the double-lion Ruti.
After adding up the evidence, the original meaning
and identity of the Sphinx becomes clear.
To its builders in the Old Kingdom, the Sphinx, as a lion,
was a symbol of the king.
Like Ruti, the Sphinx was also a god--
guardian of the horizon, the entrance to the afterlife.
The solar alignment on the equinox reveals
that the Sphinx, Sphinx Temple and Khafre'
are intimately connected.
Their singular purpose was to ensure
the pharaoh' to the afterlife.
It is Khafre' the Sphinx,
which protected the mummified king
as he traveled toward the pyramid,
following the path of the sun over the horizon.
Back in New England, Rick Brown and his team
are finally completing their scaled-down Sphinx nose.
They' touches using replicas
of ancient copper chisels in hopes of estimating
how long it took to carve the Great Sphinx.
LEHNER: Hey, Rick.
Mark.
So, you guys have been at it two weeks?
Just over two weeks.
All day long, every day.
Every day all day?
Well, that' looking nose job.
I' how many hours total
it took for this nose, because that might give us an idea
how long it took to carve the Great Sphinx.
NARRATOR: Although Brown had resorted at times to using modern machinery
to speed up the carving, he'
to work out how long it would have taken
using just ancient tools.
We calculated we could do 200 hits in five minutes,
over and over again, and sustain that for an eight-hour day.
NARRATOR: By measuring the amount of stone chipped away,
he can calculate how much stone one worker could remove.
BROWN: It would take 40 hours
for one person to remove one cubic foot of stone.
NARRATOR: Based on Lehner'
they calculate how much stone was removed
from around the Sphinx.
LEHNER: So that big block and that big block,
you got those out of there.
NARRATOR: From there, it' to get the final figure
for how long it would have taken to carve the whole Sphinx.
LEHNER: So now we can use this, we figure like a hundred carvers?
And you come out with a million?!
Around a million hours.
A million person-hours to carve the great Sphinx?
Well, that'
NARRATOR: And if they spread that million hours over 100 people,
they come up with a rough estimate.
It would take a hundred carvers three years to carve the Sphinx.
A hundred carvers, three years.
NARRATOR: But by carving the scaled-down nose,
Brown and Lehner have discovered that those 100 people
for three years is just one part of a greater enterprise.
To build the Great Sphinx, there must have been an army of people
cutting wood to stoke fires and forges, making tools,
sharpening tools, running them back and forth
and pounding away at the giant rock
that would become the Sphinx.
RICK BROWN: People was the power of Egyptian times.
That' the pyramids,
that' the Sphinx.
NARRATOR: That people power used to build the Sphinx and the pyramids
did even more than create monuments we still admire today.
LEHNER: Marshaling all their human and natural resources
to create this monumental complex at Giza
must have had a huge effect on the Egyptian state
and its economy.
The pyramids and the Sphinx did as much to build Egypt
as the Egyptians did to build them.
NARRATOR: Building the pyramids and the Sphinx actually built Egypt.
And the clues to solving the riddle of the Sphinx
were hidden in plain sight.
LEHNER: The record was in the geology.
It was in the archaeological record.
It was in the changes
that the ancient Egyptians made to the landscape
for building things like the Sphinx.
NARRATOR: Animal, human and god...
carved from the very earth
and inspiring the imagination of people throughout time.
The Great Sphinx has achieved the dreams
of its creators: eternal life.
