Memphis was believed to be under the protection of the god Ptah, the patron of craftsmen. Its great temple, Hut-ka-Ptah (meaning "Enclosure of the ka of Ptah"), was one of the most prominent structures in the city. The name of this temple, rendered in Greek as Aἴγυπτoς (Ai-gy-ptos) by Manetho, is believed to be the etymological origin of the modern English name Egypt.
The history of Memphis is closely linked to that of the country itself. Its eventual downfall is believed to have been due to the loss of its economic significance in late antiquity, following the rise of coastal Alexandria. Its religious significance was diminished after the abandonment of the ancient religion following the Edict of Thessalonica (380 AD), which made Nicene Christianity the sole religion of the Roman empire.
The fertile land, the river and the sea were the source of life for ancient Egypt.
The fundamental occupation for most of the population was undoubtedly agriculture.
And power, both in politics and religion, was based on the ownership of land.
The first pharaohs were tillers of the soil.
The essence of Egyptian ethics and of its highest spiritual thought,
to be found in the myth of death and resurrection of Osiris, springs from the world of agriculture.
The exceptional intellectual potential of the Egyptian people
emerged with the fertility of the fields, the annual flooding of the Nile.
By August, all the land was covered with water,
and only the cities and towns emerged like islands from the immense boundless swamp.
With the winter solstice, the immense lagoon withdrew and disappeared.
Life was reborn in the wake of desolation.
In the past, navigation on the Nile was particularly favoured by nature.
The ships plying the river from south to north, and thus towards the sea,
were aided by the current.
Those going upstream from lower to upper Egypt
had an almost constant north-south breeze to help them along.
The Nile not only fertilised the land, but also became the lifeline
and the communications network for all Egypt.
Knowledge of the astronomical calendar was the result of ancient observations
and study of the sun's course in relationship with the fixed stars.
Every year was divided into three seasons.
The flood season, Akhet.
The sowing season, Peret.
The harvesting season, Shemu.
The Egyptian was familiar with operations, some type of fractions,
the calculation of surfaces and volumes,
which permitted them to develop great networks of canals and lots.
Much more complex and demanding was the work concerned with regulating
the flooding of the fields and which involved skills that were unique at that time,
requiring knowledge in the variety of fields,
astronomy, land surveying, hydraulics, construction,
as well as the capacity to programme and organise exceptional operations
to be carried out over thousands and thousands of hectares of land.
It meant an acquaintance with the astrological calendar
and understanding of instruments for measuring and levelling,
of how to escalate canals, dams, bridges and regulate and lift water.
In 2000 BC, a large region around Lake Meoris was made arable
by canalising and reclaiming thousands of hectares of marshy, sterile land.
This great work also included the construction of villages
and the construction of cooperatives.
Each village had workers of the land who had a house of their own with a garden.
They belonged to a team of five workers who formed a responsible community
which annually discussed the programmes with the delegates of the State of Property
for the consignment of the products and regulation of remuneration.
There are no forests in Egypt, so wood is scarce and is not used for house building.
The earliest inhabitants of Egypt lived in huts made from papyrus reeds.
However, it was soon discovered that the mud left behind after the annual flooding of the Nile
could be made into bricks which could be used for building.
Bricks were made by mixing mud and straw and leaving them to dry in the sun.
In ancient Egyptian society, as well as today, farming was very important.
The farmer had to provide food for tradesmen, leaders and slaves.
He worked very hard along the fertile Nile River valley.
This valley provided fine soil for raising grain, vegetables and fruits.
None of the achievements of the remarkable ancient Egyptian civilisation
would have been possible without the Nile River.
There's always a connection between landscape and how a people develop.
There are days when the sand blows ceaselessly,
blanketing the remains of a powerful dynasty that ruled Egypt 5,000 years ago.
When the wind dies down and the sands are still,
a long shadow casts a wedge of darkness across the Sahara,
creeping ever longer as the North African sun sinks beyond the horizon.
This is where our history of Egypt begins, in the shadow of the Great Pyramid of Giza,
where stone meets sky as a testament to one of the greatest civilisations on earth.
The World of the Pyramids is an apt name for the series of cemeteries
which lie along the western bank of the Nile,
stretching from the ancient city of Leopolis almost as far as Heracleopolis.
Egypt rouses a level of mystique and awe in travellers that few nations in the world can match.
The most prevalent colour of the desert, however, is a decidedly reddish-yellow ochre.
Just a few minutes south of Cairo, on the west bank of the Nile,
the Pyramids of Giza rise out of the desert expanse,
a tribute thousands of years old to an ancient culture.
The peoples of ancient Egypt seem like bearers of some higher civilisation
whose sources lay in another world.
While populations elsewhere were groping their way out of the Stone Age,
generating cultures that were on more or less the same level in all the religions of the world,
the Egyptians seem to have been born adult.
They soon broke through the barriers of human possibility 6,000 years ago,
almost in virtue of experiences sustained in some other extraordinarily civilised world.
With its soaring pyramids, sacred tombs, complex hieroglyphs, ancient temple walls,
legends of exotic pharaohs and colourful pantheon of gods,
ancient Egypt is easy to be captivated by the landscape of a culture
that fills the imagination with its richness and depth.
Giza is the name currently given to the gigantic burial grounds of the ancient Leopolis,
which cover an area of 2,000 square metres on a plateau.
The great architectural achievements of the past are built of stone.
Stone quarries supplied the large blocks of granite, limestone and sandstone
that were used for building temples and tombs.
Architects planned carefully, as building was done without mortar,
so the stones had to fit precisely together.
Only pillars were used to sustain short stone supports.
The art of the Egyptians reflects every aspect of their lives.
Depicted in tomb and temple drawings are scenes of everyday life,
models of people and animals, glass figures and containers.
The physical geography of ancient Egypt has remained in the form of pyramids and temples,
and the wealth of knowledge that this civilisation was able to develop
leaves many visitors feeling inspired.
One of the most notable and lasting achievements of the ancient Egyptians are their pyramids.
The size, design and structure of the pyramids reveal the skill of these ancient builders.
The pyramids were great monuments and tombs for the kings.
The Egyptians believed that a king's soul
continued to guide affairs of the kingdom even after his death.
To ensure that they would continue to enjoy the blessings of the gods,
they preserved the pharaoh's body through the mummification process.
They built the pyramids to protect the body,
and it was a symbol of hope,
because it would ensure the pharaoh's union with the gods.
The Great Pyramid of Khufu at Giza
is the largest single building ever constructed.
On the Giza plateau,
Khufu's builders oriented his pyramid almost perfectly north.
Surrounded by a myriad of matabas,
or oblong-shaped flat-topped tombs with sloping sides,
a great many of the pyramids are smooth-faced,
while a few are stepped.
Almost at their head stand the monumental pyramids of Giza.
The golden period of the stepped pyramids
lasted not much more than 100 years,
while that of the geometric pyramid lasted 500 years.
The pyramid gives the impression of an immense flight of stairs
which leads to infinity.
The impression is heightened by the total absence of the facing,
so that the internal blocks,
arranged like a giant staircase, are revealed.
Originally 146 metres high,
it now measures 137 metres,
and a plaza 10 metres wide
lies where the summit once was.
Of the original 2,500,000 cubic metres of stone blocks,
weighing from 2 to 15 tonnes each,
there are now only 2,350,000,
which means that by the early 19th century,
150,000 cubic metres of fine-cut stone
had been removed for the construction of Cairo.
The materials used in particular for the Great Pyramid of Khufu
fall into two distinct categories,
granite monoliths and blocks of limestone.
The differences in number and weight
resulted in two types of construction yards,
monolith construction yards and block construction yards.
It should be kept in mind that the technique was dry-joint masonry,
without mortar or blinder of any sort,
in which the blocks were simply set or mounted on top of each other.
When the Greek historian Herodotus visited Giza in about 450 BC,
he was told by Egyptian priests
that the Great Pyramid had been built for the pharaoh Khufu,
Cheops to the Greeks,
who was the second king of the fourth dynasty.
In addition to these three monuments,
small pyramids were built for three of Khufu's wives
and a series of flat-topped pyramids
for the remains of his favourite children.
There were three satellite pyramids
on the north side of the Great Pyramid of Giza,
which are often referred to as the Queen's Pyramids.
The northernmost pyramid is now considered
to be the secondary burial of Queen Hetephares I.
The second pyramid is now ascribed to Queen Merititis,
and the southernmost of the three pyramids
was built for Queen Henoutzen.
The Great Pyramid was the centrepiece of an elaborate complex
which included several small pyramids,
five boat pits,
a mortuary temple,
a causeway,
a valley temple,
and many flat-roofed tombs for officials
and some members of the royal family.
Dignitaries and nobles were also commonly buried in tombs
set around the pyramid,
and known now as mastabas.
They were rectangular in plan,
with slightly sloping walls,
a cornice moulding around,
and a single entrance door.
Soon after its construction,
Khufu's son and grandson built the other two pyramids,
completing what visitors commonly recognise
as the Pyramids of Giza.
While the three largest structures are the most attention-grabbing,
the Giza Plateau is a complex
including many other ancient buildings,
among them the Great Sphinx,
a colossal stone statue.
Fashioned from an outcrop of limestone,
left behind from the quarrying of stone for the Great Pyramid,
the Sphinx crouches in a rectangular ditch
bounded by Khafre's causeway to the south,
a modern road to the north,
and Old Kingdom's Sphinx Temple to the east.
A small reconstructed New Kingdom religious structure,
probably dating from Amenhotep II,
lies to the northeast.
The colossal figure is oriented east to west,
and the Sphinx Temple,
with its huge courtyard,
has been called a solar temple.
The Sphinx can be identified with the god Re,
who rises and sets on the horizon,
and also with Horus, the son of Re.
The head of the Sphinx represents an Egyptian ruler
wearing a Nemer's headdress
and once had a Uraeus serpent on its forehead
and a royal beard.
The human head is small in proportion to the lion's body
and it's suggested that the body may have been elongated
to take into account a natural fissure in the rock
which would have prevented the workmen.
The colossal statue takes the form of a crouching lion
with a human head,
thought to be carved with the features of Khafre,
though this is the subject of some debate.
Sphinxes are typical elements of Egyptian statuary,
but the unique architecture of the Great Sphinx
has long fired the imaginations of archaeologists,
who assert that the sculpture is the work of a civilization
far more ancient than the builders of the pyramids.
While the enigmatic history of the Sphinx is undeniable,
recent intensive excavations and restorations
have revealed no secret subterranean chambers
or evidence of vanished civilizations.
The body of the Sphinx,
almost 60 metres long and 20 metres high,
was carved from alternate soft and hard layers of sediments
of Marley limestone laid down
during the formation of the Giza Plateau
in the geological Eocene period.
The harder layers were quarried blocks
extracted for Old Kingdom building projects,
and it's now possible to identify the stone
used in each of the nearby structures,
providing evidence of the sequence of quarrying.
The walls of Khafre's valley temple
were probably composed of massive blocks
from the upper part of the Sphinx's body,
while some of the limestone blocks of the Sphinx temple
came from an area around the Sphinx's chest.
The ancient Egyptian pyramids
are often thought of as the quintessential symbol
of the high level of achievement and skilled engineering.
In eastern North Africa,
ancient Egypt has a long history,
with periods of success and decline
spread over 3,000 years.
The greatest pyramids symbolise a time
in ancient Egyptian history
when pharaohs ruled absolutely
and in turn were buried in grand ways.
Ancient Egypt was a sophisticated society
that laid the groundwork for modern civilisation.
Today, the artefacts of the Egyptians
are on display all over the world
and make up some of the most popular exhibits
in contemporary museums.
They participated in trade,
spreading their papyrus to different regions of the world
in exchange for rare goods.
Today, ancient Egypt is remembered
for the complex hieroglyphics,
awe-inspiring architecture,
civilised society and intricate art.
With the abundance of ruins around the country,
Egypt has the remnants
of one of the greatest civilisations in history.
The second largest pyramid of Giza
was built for Khufu's son, Khafre,
Chephren,
who became the fourth king of the fourth dynasty
after the death of his short-lived elder brother
and died around 2532 BC.
Although many of his relatives
were hastily buried in cheap tombs,
the Pyramid of Khafre
is almost as vast as the Great Pyramid of his father.
The estimated weight of all the stones in the pyramid
is 4,880,000 tonnes.
Because it's built higher on the plateau,
it looks taller from most angles
than Khufu's pyramid.
The top of the pyramid
still has some of the limestone casing
that once covered the entire pyramid.
Pyramids today stand as a reminder
of the ancient Egyptian glorification
of life after death.
And in fact,
the pyramids were built as monuments
to house the tombs of the pharaohs.
Death was seen as merely the beginning
of a journey to the other world.
In this society,
each individual's eternal life
was dependent on the continued existence of their king,
a belief that made the pharaoh's tomb
the concern of the entire kingdom.
The function of the pyramids
was clearly indicated as a burial of pharaohs.
The entire complex began functioning
as soon as the funeral of the deceased began.
When the pharaoh died,
the long rites of his embalming and burial
began at the temple dwelling of the pharaoh.
Once the body had arrived
with the procession of the sacred barks,
the purification ceremonies began
at the valley of the temple,
and the preparation of the mummy
was also completed.
The principal ceremony
was the purifying washing,
comparable to that of the sun,
which is reborn every morning.
Purified,
covered with perpetuatory amulets,
the mummy passed to the guardian of the threshold,
then began his journey of ascent,
hidden from profane eyes in the gallery,
and reached the temple
further up for the consecration.
As the body proceeded
from one columned hall to the next,
the number of initiates and purified
who accompanied him dwindled.
When it reached the great central court,
only the great initiated and the pharaoh heir
continued into the sancta sanatorium
of the mortuary temple,
where the fundamental ceremony
of the opening of the mouth and eyes took place.
The royal heir presided over this rite,
which opened the communication of the deceased
with the afterworld,
before the five chapels in the otherworld,
the five statues of the god-king,
one for each attribute given to the pharaoh
when he'd received his royal consecration.
Officially reunited with the gods,
the deceased was taken through secret ways
to the subterranean chapel,
once sealed, the precious sarcophagus
was set in the midst of his dearest possessions
and treasures,
after which the worker priests
retraced their steps,
closed the marble portcullises,
and obstructed every passage
so that no one might disturb the pharaoh
as he waited for his final ascent to the sun.
The pyramid is a symbol of the sun,
the great god Re,
whose cult became preeminent
from the fourth dynasty.
The pyramid texts,
found in the funerary chambers of the tombs,
dating from the end of the old kingdom,
speak of the transformation
of the dead king into the sun.
Like all great religions,
that of the ancient Egyptians
was basically monotheistic,
as was that of their ancestors
in prehistoric times,
with the cult of mother goddess,
the generating force of all things,
of gods and man.
The religion born with the planet Egypt,
when the great turning opine
in the history of civilization was achieved,
was even more so.
All Egyptian cosmogenies
are deeply permeated
by the feeling of one unique absolute god,
of an eternal creation,
where the gods have a thousand faces
and are the thousand manifestations
of the same god,
as are all his creatures
and all of mankind.
From any angle,
Giza's pyramids inspire awe.
The pyramids have risen above the desert
outside Cairo
for more than 4,000 years.
Saqqara is one section
of the great necropolis of Memphis,
the old kingdom capital,
and the kings of the first dynasty,
as well as those of the second dynasty,
are mostly buried
in this section of the necropolis.
It's been of constant interest
to Egyptologists.
Saqqara took the name of Soqar,
the old kingdom god of orientation,
the measurement of location,
and there are theories
that the ancient surveys of all Egypt
took this as their starting point.
On a clear day,
its most prominent monument,
Joseph's Step Pyramid,
can be seen from Giza,
which lies some 17km to the north,
and from Dashur,
about 10km to the south.
From Egypt's modern-day capital, Cairo,
Saqqara is some 40km away.
Three major discoveries
have recently been made at Saqqara,
including a prime minister's tomb,
a queen's pyramid,
and the tomb of the son
of a dynasty-founding king.
Each discovery has a fascinating story,
with many adventures
for the archaeologists
as they reveal the secrets of the past.
Thousands of tombs
are spread across an important area,
and covering more than 3,000 years
of complex Egyptian history.
The ruins at Saqqara
have long attracted
the interest of explorers,
grave robbers, and local people.
Travellers first reported evidence
of antiquities at Saqqara
in the 16th century.
It wasn't until Napoleon
marched into Egypt in 1798
with his conquering forces
that a scientific study
of the area began.
One of Napoleon's aims
in liberating Egypt
was to bring modern scientific inquiry
to the study of its monuments.
The General established
the Institut de l'Egypte
and dispatched hundreds of scientists
to document Egypt's
antiquities in depth.
The resulting publication,
The Description of Egypt,
was a lavishly produced catalogue
of ancient Egyptian sites,
including Saqqara.
Saqqara represents
the first complete model
of the typical pyramid complex,
including enclosure walls
and a causeway.
It offers a myriad of sites to visit,
aside from the Pyramid of Joseph.
Covering a few kilometres square,
its dusty expanse
is dotted with various pyramids
built for the rich and famous
of an era long gone by.
Next to the pyramid texts,
the causeway is the most impressive part
of Unas' funerary complex.
With its 750 metres in length,
it must have been
one of the longest pyramid causeways
ever constructed,
equalled only
by the Causeway of Cheops at Giza.
The causeway connects
the mortuary temple
to the valley temple.
It was built in a long wadi
that opened onto a lake
east of the pyramid.
Some of the blocks
used to fill gaps
in the embankment
came from the enclosure
of Joseph's complex,
which suggests
that by the end of the Fifth Dynasty,
Joseph's complex
had already fallen into decay.
Only bits and pieces
of the original decoration
of the inner walls
of the roofed causeway
have been found.
They can merely hint
at the diversity of scenes
that covered the causeway.
Part of the decoration
appears to have been dedicated
to the representation
of the building
of the funerary complex.
The transport by boat
of the granite palm columns
for the mortuary temple
and craftsmen
working gold or copper.
In order to connect
the valley temple
to the mortuary temple
and in order to follow
the natural wadi,
the causeway shows
bends twice to the south.
At the uppermost bend,
two boat pits,
each 45 meters long,
have been found
immediately to the south
of the causeway.
The causeway
has recently undergone restoration
and one can now walk
from the valley temple
along the causeway
to the pyramid.
The remains of the doorway
indicate the entrance
of Unas's mortuary temple.
The right door jamb
of the entrance
to the mortuary temple
has been inscribed
with fine hieroglyphs.
The pyramid of Unas,
even though the smallest
of the old kingdom royal pyramids,
is considerably more famous
and better known
than the king who built it.
This is because,
for the first time
that we know of,
the 128 magical spells
of the pyramid text
appear on the walls
of its subterranean chambers.
It was once called
beautiful are the cult places
of Unas.
The Heb Sed court
is located on the east side
of the courtyard
between the entrance corridor
and the house of the south.
There are no inscriptions
to confirm the purpose
of the buildings
in this courtyard,
but it's considered likely
that it related
to the Heb Sed festival.
Within the courtyard,
there are three types of chapel,
each preceded by a small court.
Each shrine has a doorway
which penetrates the outer wall
but goes no further.
The southernmost shrine
incorporates the podium
with round fronted steps
which formed the base
of the tents
which would be set up
during the festival.
This form emulates
the hieroglyph
which stands for the festival.
The step pyramid
is the first known
monumental structure
made of stone
anywhere in the world.
As its name suggests,
it's a series of
six levels of stone
decreasing in size
as they ascend
to about 60 meters in height.
Until this time,
mastabas had been
the principal form
of tomb architecture.
A mastaba,
Arabic for bench,
is a low rectangular structure
which was built over a shaft
which descended
to the burial location.
Saqqara is best known
for the step pyramid,
the oldest known
of Egypt's 97 pyramids.
It was built for King Djoser
of the third dynasty
by the architect and genius
Imhotep
who designed it
and its surrounding complex
to be as grand as it was
unique and revolutionary.
Imhotep was the first
to build stone tombs
in honor of the king's majesty.
His many titles included
treasurer of the king
of lower Egypt,
administrator of the great palace
and Imhotep the builder,
the sculptor,
the maker of stone vessels.
Imhotep may also have designed
the pyramid of Djoser's successor,
Sekemket.
Extensive use of stone
here and there
carved to resemble wood,
reeds or other softer materials
made the tomb more durable
than its mud brick forebears.
The step pyramid complex
was enclosed by a 10 meter wall
and included courtyards,
temples and chapels
covering nearly 16 hectares,
the size of a large town
in the third millennium BC.
Various missions have been active
in Saqqara.
After World War II,
archaeological research at Saqqara
became an international affair.
Among the numerous expeditions,
only a few can be singled out here.
Much fieldwork has been done
by Egyptian archaeologists
working for the Antiquities Service.
Most famous was the discovery
of the unfinished step pyramid
of Sekemket by Zakaria Gonaim.
The escarpment rises about
30 meters above the valley.
It consists of limestone cliffs
alternating with sandy slopes
and interrupted by a number of wadis,
dry riverbeds.
In the west,
the Saqqara plateau is cut off
from the high desert
by another less conspicuous wadi.
The total dimensions of the plateau
from east to west
are about one and a half kilometers.
From north to south,
about six kilometers.
The steep cliffs of the eastern desert,
a mountainous area
stretching all the way to the Red Sea.
Like their modern descendants,
the ancient Egyptians
lived in the fertile valley.
The deserts were only visited
to obtain building stone,
ores and minerals.
From the edge of the Saqqara plateau,
one can gaze down over the Nile Valley,
a narrow strip of green fields
and date palms.
Located to the southwest of Memphis,
some 10 kilometers
to the south of Saqqara
and some 40 kilometers
north of Meydam,
Dashur is the most southern site
of the Memphite necrophilis,
which stretches to Abu Rawash
in the north.
Dashur owes its modern-day name
to the nearby villages
Dashur and Minset-Dashur.
This name may perhaps come
from the Coptic name Tasur
or Tacorus in Greek,
the ancient Egyptian name
for this area may well be mentioned
in the story of Sinuhe.
This southernmost part
of the Memphite necropolis
stretches over an area
of approximately 3 to 3.5 kilometers
from north to south
and 2 to 2.5 kilometers
east to west.
It starts at about 1.5 kilometers
to the west of the fertile ground.
Although at the time
the area was used as a necropolis,
this may well have been different.
Sneferu was one of the most
prolific builders of ancient Egypt.
Not content with building
a step pyramid at Meydam
and the bent pyramid at Dashur,
Sneferu also built
the red pyramid at Dashur.
It's often suggested
that he was very keen
to build a true pyramid
and that he was displeased
when he was forced to change
the angle of the bent pyramid
as the weight of the masonry
threatened to cause
that pyramid to collapse.
Whether this is the case
the angle of the red pyramid
is close to the top section
of the bent pyramid,
around 43 degrees.
Stripped from its limestone casing,
this new pyramid has a reddish color,
hence its modern-day name
the red pyramid.
When it was first built
it was clad with fine white limestone
and was named Sneferu Shines,
Sneferu Rises,
or Sneferu Appears.
The pyramid gets its common name
from the reddish limestone
used to build most of its core,
but it's also sometimes referred to
as the Shining or Northern Pyramid.
Learning from prior mistakes,
several layers of fine white limestone
were used to lay the pyramid's foundation,
thus eliminating the structural problems
of earlier pyramids.
Tura limestone was used as casing stone
to cover the pyramid.
Though some casing still remains,
most has been removed.
East of the pyramid
is what remains of a mortuary temple.
As well as the first capstone,
called a pyramidion,
ever found,
belonging to an old kingdom pyramid.
It was recovered in fragments
and reconstructed.
The Bent Pyramid is unique for two reasons.
The first is the angle change.
There are two theories for this change.
The first is that the builders
may have become tired
and wanted to reduce the volume
and finish faster.
Another is that when the pyramid
at Maidum collapsed,
the architect lost his nerve
and changed the angle.
The angle at Maidum was 52 degrees,
as is the base of the Bent Pyramid.
At the bend,
the angle is changed to 43.5 degrees
up to its peak.
The Bent Pyramid was built out of limestone,
which was quarried locally.
The casing was of polished Tura limestone.
This pyramid is also known
as the Southern Shining Pyramid.
The casing blocks are very stable
and very difficult to remove
because they slope inwards.
The base of the pyramid
is 188.6 metres
and is 105 metres high.
Because of the bend in construction,
the original angle
would have made it 128.5 metres high.
The Bent Pyramid of Sneferu
is the oldest monument at Dacia.
It also represents the first attempt
to build a true pyramid.
The Ensemble at Memphis
embraces a number of exceptional monuments
of great antiquity.
At Giza,
one of the oldest boats preserved today,
the Solar Barge,
was discovered intact
in the complex around the Pyramid of Cheops.
The archaic necropolis of Saqqara
dates back to the period of the formation
of the Pharaonic civilization.
The exceptional historic, artistic
and sociological interest of these monuments
bears witness
to one of the most brilliant civilizations
of this planet.
