When was the Cheops pyramid built? Ancient pyramid of Cheops, Egypt Who built the pyramid of Cheops

The Pyramid of Cheops is a rare case in Egyptology when we can be sure who owns the monument. Often the ancient monuments of Egypt were appropriated by later rulers. The technology of appropriation was very simple - the name of the pharaoh-builder (cartouche) was simply lost from the inscriptions in the temple or in the tomb, and another name was knocked out.

This phenomenon was very common. Take, for example, the famous Pharaoh Tutankhamun. Until 1922, when archaeologist Howard Carter dug up, Egyptologists doubted the existence of this ruler. There was almost no written evidence about him; everything was destroyed by subsequent pharaohs.

In the 19th century, archaeologists often used very barbaric research methods. In the Cheops pyramid, gunpowder explosions were used to find hidden rooms. You can still see traces of such methods on the surfaces of structures (see photo on the left).

During this study, small rooms were discovered above the main burial chamber. Explorers rushed there in the hope of finding treasure, but, of course, there was nothing there except dust.

These rooms, only 1 meter in height, had a purely technical purpose. These are unloading chambers; they protect the ceiling of the burial chamber from collapse and relieve mechanical stress. But it was on the walls of these unloading chambers that scientists discovered inscriptions made by ancient builders.

These were block markings. Just as we now put a label on a product, the ancient Egyptian foremen marked the blocks: “This block is for the pyramid of Khufu, produced at that time, laid at that time.” These inscriptions cannot be fake; they prove that this structure was built by Cheops.

A little about Pharaoh Cheops

In the last paragraph we used the name “Khufu”. This is the official Egyptian name of this pharaoh. Cheops is the Greek interpretation of his name, and not the most common one. Other pronunciations “Cheops” or “Kiops” are more common.

The name “Khufu” is more common in the world. If you are going on an excursion to Giza with a Russian-speaking guide, then there will be no problems, he will be aware of this phonetic difference. But, if you communicate with locals or tourists from other countries, we recommend using the name “Khufu”.

Although Pharaoh Khufu is one of the, it is impossible to write much about him. We know very little about him.

In addition to the fact of the construction of this pyramid, we know that Khufu organized expeditions to develop useful resources in the Sinai Peninsula. That's all. To this day, only two artifacts have survived from Khufu - a giant pyramid 137 meters high and a small ivory figurine only 7.5 centimeters high (pictured on the right).

Pharaoh Cheops remained in people's memory as a tyrant ruler who forced people to work on grandiose construction. We can read about this in the works of the Greek historian Herodotus, who visited Egypt and recorded the stories of the priests.

Surprisingly, his father Pharaoh Snefru remained in people's memory as a very kind ruler, although he built as many as three pyramids (and) and overexerted the country twice as much as Cheops.

The only one of the 7 wonders of the world that has survived to this day is the Pyramid of Cheops, or the Pyramid of Khufu, as the Egyptians themselves call it, unlike the rest of the world, which uses the Greek pronunciation of the name of the pharaoh.

To fully understand how far from us are those times when the Cheops Pyramid was built, one only has to think that for contemporaries of the other six wonders of the world, the Great Pyramid of Giza was so old that they no longer knew the answer to its mystery.

Despite the fact that the largest pyramid in the world is more than four thousand years old, it has been quite well preserved to this day. Today, excursions to the Egyptian pyramids can be booked from almost any hotel in Cairo.

History and construction of the Great Pyramid of Cheops

It is believed that a certain Hemion, the pharaoh’s nephew and vizier, and, by extension, also a court architect, was involved in bringing the royal ambitions to life. The Pyramid of Cheops was built around 2540 BC, and its construction began twenty years earlier - somewhere in 2560 BC.

More than two million huge stones were needed to build the Great Pyramid of Giza. The largest blocks weighed several tens of tons. For the structure weighing 6.4 million tons, so that it does not sink underground under its own weight, strong rocky soil was chosen. Granite blocks were delivered from a quarry that was located 1000 km away. Scientists still cannot find the answer to the question of how these stones were transported and how the Cheops pyramid was built

The purpose of the tallest pyramid in Ancient Egypt also causes a lot of controversy. According to the most common opinion, this is really the tomb of Cheops (the second pharaoh of the IV dynasty of rulers) and members of his family. But nevertheless, discussions around the mystery of the pyramid do not subside. For example, from the point of view of some astronomers, some kind of observatory was equipped here, since the ventilation ducts and corridors point with amazing accuracy to the stars Sirius, Thuban, and Alnitak. It is also interesting that during the construction of the Cheops pyramid, the coordinates of the Earth’s magnetic poles were also taken into account.

Geometry and description of the pyramid of Khufu

The size of the Cheops pyramid surprises even modern people. Its base occupies a huge area of 53 thousand square meters, which is equivalent to ten football fields. Other parameters are no less striking: the length of the base is 230 m, the length of the side edge is the same, and the area of the side surface is 85.5 thousand square meters.

Now the height of the Cheops pyramid is 138 meters, but initially it reached 147 meters, which can be compared to a fifty-story skyscraper. The years have left their mark on the safety of the pyramid. Numerous earthquakes over thousands of years collapsed the stone top of the structure, and the smooth stone with which the outer walls were lined crumbled. And yet, the interior of the attraction, despite many robberies and vandals, remained virtually unchanged.

The entrance to the pyramid, located on the north, was originally at a height of almost 16 meters and was sealed with a granite plug. Now tourists get inside through a huge gap made ten meters below, left in 1820 by the Arabs led by Caliph Abdullah al-Mamun, who attempted to find treasures supposedly hidden here.

Inside the Cheops pyramid there are three tombs, located one above the other. The lowest, unfinished underground chamber is located at the base of the rock. Above it are the burial chambers of the queen and pharaoh, to which the rising Great Gallery leads. Those who built the pyramid created a complex system of corridors and shafts, the plan of which is still being studied by scientists. Egyptologists have put forward a whole theory of understanding the afterlife of people of that time. These arguments explain the secret doors and other design features.

For many years now, the Pyramid of Pharaoh Cheops in Giza, like the Great Sphinx, has been in no hurry to reveal all its secrets. For tourists, it remains the most striking attraction of Egypt. It is impossible to fully comprehend the secrets of its corridors, shafts and ventilation ducts. Only one thing is clear: the Great Pyramid is the fruit of a brilliant design idea.

There are many opinions about when the Cheops pyramid was built and who did it. The most original assumptions are various versions of construction completed long before the Flood by civilizations that did not survive it, as well as hypotheses about alien creators.
Despite the fact that no one knows the exact time when the Cheops Pyramid was built, in Egypt the date of the start of its construction is officially celebrated - August 23, 2560 BC.
The latest excavations, carried out at the beginning of the 21st century, indicate that the work of the pyramid builders was difficult, but at the same time they were well cared for. They had a high-calorie diet of meat and fish and comfortable sleeping places. Many Egyptologists are of the opinion that they were not even slaves.
Studying the ideal proportions of the Great Pyramid of Giza, scientists came to the conclusion that already in those days the ancient Egyptians knew very well what the golden ratio was and actively used its principle when creating a drawing.

There are no decorative paintings or historical inscriptions inside the Cheops pyramid, except for a small portrait in the passage to the queen's chamber. There is not even any evidence that the pyramid even belonged to Pharaoh Khufu.
Until 1300, for three millennia, the Great Pyramid was the tallest man-made structure on the planet, until Lincoln Cathedral was built to surpass it.
The heaviest stone block used in the construction of the pyramid weighs 35 tons and is placed above the entrance to the pharaoh's burial chamber.
Before the Vandal Arab invasion of Egypt, the outer slabs of the Cairo pyramid were so carefully polished that in the light of the moon they emitted a mysterious shimmer, and in the rays of the sun their cladding shone with a soft peach light.
To explore rooms that are difficult for humans to reach, scientists used a special robot.
From 6 to 10 thousand tourists visit the pyramids every day, and about 3 million per year.

Useful information for tourists

Currently, in the museum on the south side of the pyramid you can get acquainted with exhibits that were found during excavations and in the pyramid itself. There is an opportunity to see the restored unique cedar boat (Solar Boat), which was built by the ancient Egyptians. You can also buy souvenirs here. And the next viewing point on the territory will be the Great Sphinx.

In the evenings, a sound and light show is shown in Giza: alternating spotlight illumination of local attractions is accompanied by a fascinating story, including in Russian and English.

Opening hours of the Giza Museum complex

daily from 8.00 to 17.00;
in winter – until 16.30;
during Ramadan - until 15.00.

Ticket prices

entrance ticket to the Giza zone for foreigners – $8;
entrance to the Cheops pyramid – $16;
inspection of the Solar Boat – $7.

For children and students, prices are usually two times lower.

To visit the Cheops Pyramid, only 300 tickets are sold per day: 150 at 8.00 and 150 at 13.00.
It is best to go to the pyramids in the morning to grab a ticket and protect yourself from the midday heat.
The entrance to the pyramid is very low, you will have to walk 100 meters bent over, and it is also very dry, hot and slightly dusty inside. Water is not recommended for people suffering from claustrophobia, diseases of the respiratory tract and heart.
Photo and video shooting is prohibited inside. As for photographs against the backdrop of the Great Pyramid, it is better not to give your camera into the wrong hands, as there are frequent cases of theft.
It is better to take a photo of the Cheops pyramid (as well as other pyramids) in the morning or evening, when the sun is not shining too brightly, otherwise the image will turn out flat.
Climbing the pyramid is strictly prohibited.
For local residents, tourists are the main and often the only source of income, so you will constantly be offered to buy something. Therefore, think carefully about whether you need certain offers, and in any case, be sure to bargain. Give tips only to those who truly deserve them.
Be careful: there are a lot of pickpockets around.

Age of the pyramid

The architect of the Great Pyramid is considered to be Hemiun, the vizier and nephew of Cheops. He also bore the title "Manager of all Pharaoh's construction projects." It is assumed that the construction, which lasted twenty years (during the reign of Cheops), ended around 2540 BC. e. .

Existing methods for dating the start of construction of the pyramid are divided into historical, astronomical and radiocarbon. In Egypt, the date for the start of construction of the Cheops Pyramid was officially established (2009) and celebrated - August 23, 2560 BC. e. This date was obtained using the astronomical method of Kate Spence (University of Cambridge). However, this method and the dates obtained with it have been criticized by many Egyptologists. Dates according to other dating methods: 2720 BC. e. (Stephen Hack, University of Nebraska), 2577 BC. e. (Juan Antonio Belmonte, University of Astrophysics in Canaris) and 2708 BC. e. (Pollux, Bauman University). Radiocarbon dating gives a range from 2680 BC. e. to 2850 BC e. Therefore, there is no serious confirmation of the established “birthday” of the pyramid, since Egyptologists cannot agree on exactly what year construction began.

First mention of the pyramid

The complete absence of mention of the pyramid in Egyptian papyri remains a mystery. The first descriptions are found in the Greek historian Herodotus (5th century BC) and in ancient Arab legends [ ] . Herodotus reported (at least 2 millennia after the appearance of the Great Pyramid) that it was built under a despot pharaoh named Cheops (Greek: Cheops). Koufou), who ruled for 50 years, that 100 thousand people were employed in construction. for twenty years, and that the pyramid is in honor of Cheops, but not his grave. The real grave is a burial near the pyramid. Herodotus gave erroneous information about the size of the pyramid, and also mentioned about the middle pyramid of the Giza plateau that it was built by the daughter of Cheops, who sold herself, and that each building stone corresponded to the man to whom she was given. According to Herodotus, if “to lift the stone, a long winding path to the grave was revealed,” without specifying what kind of pyramid we are talking about; however, the pyramids of the Giza plateau did not have “winding” paths to the tomb at the time Herodotus visited them; on the contrary, the Descending Passage of BP Cheops is distinguished by careful straightforwardness. At that time, no other premises were known in the BP.

Appearance

Surviving fragments of the pyramid's cladding and the remains of the pavement surrounding the building

The pyramid is called "Akhet-Khufu" - "Horizon of Khufu" (or more accurately "Related to the firmament - (it is) Khufu"). Consists of limestone and granite blocks. It was built on a natural limestone hill. After the pyramid has lost several layers of cladding, this hill is partially visible on the eastern, northern and southern sides of the pyramid. Despite the fact that the Cheops pyramid is the tallest and most voluminous of all the Egyptian pyramids, Pharaoh Sneferu built the pyramids in Meidum and Dakhshut (Broken Pyramid and Pink Pyramid), the total mass of which is estimated at 8.4 million tons.

Initially, the pyramid was lined with white limestone, which was harder than the main blocks. The top of the pyramid was crowned with a gilded stone - pyramidion (ancient Egyptian - “Benben”). The cladding shone in the sun with a peach color, like “a shining miracle to which the Sun God Ra himself seemed to give all his rays.” In 1168, the Arabs sacked and burned Cairo. Residents of Cairo removed the cladding from the pyramid in order to build new houses.

Height (today): ≈ 136.5 m
Side angle (current): 51° 50"
Side rib length (original): 230.33 m (calculated) or about 440 royal cubits
Side fin length (current): approx. 225 m
The length of the sides of the base of the pyramid: south - 230.454 m; north - 230.253 m; west - 230.357 m; east - 230.394 m
Foundation area (initially): ≈ 53,000 m2 (5.3 ha)
Lateral surface area of the pyramid (initially): ≈ 85,500 m2
Base perimeter: 922 m
Total volume of the pyramid without deducting the cavities inside the pyramid (initially): ≈ 2.58 million m3
Total volume of the pyramid minus all known cavities (initially): 2.50 million m 3
Average volume of stone blocks: 1,147 m3
Average weight of stone blocks: 2.5 tons
The heaviest stone block: about 35 tons - is located above the entrance to the “King’s Chamber”.
The number of blocks of average volume does not exceed 1.65 million (2.50 million m³ - 0.6 million m³ of rock base inside the pyramid = 1.9 million m 3 /1.147 m 3 = 1.65 million blocks of the specified volume can physically fit in the pyramid , without taking into account the volume of mortar in interblock joints); referring to a 20-year construction period * 300 working days per year * 10 working hours per day * 60 minutes per hour leads to a speed of laying (and delivery to the construction site) of about a block of two minutes.
According to estimates, the total weight of the pyramid is about 4 million tons (1.65 million blocks x 2.5 tons)
The base of the pyramid rests on a natural rocky elevation about 12-14 m high in the center and, according to the latest data, occupies at least 23% of the original volume of the pyramid
The number of layers (tiers) of stone blocks is 210 (at the time of construction). Now there are 203 layers.

Concavity of the sides

Concavity of the sides of the Cheops pyramid

When the sun moves around the pyramid, you can notice the unevenness of the walls - the concavity of the central part of the walls. This may be due to erosion or damage from falling stone cladding. It is also possible that this was specially done during construction. As Vito Maragioglio and Celeste Rinaldi note, the pyramid of Mycerinus no longer has such concave sides. I.E.S. Edwards explains this feature by saying that the central part of each side was simply pressed inward over time by the large mass of stone blocks. [ ]

As in the 18th century, when this phenomenon was discovered, today there is still no satisfactory explanation for this architectural feature.

Observation of the concavity of the sides at the end of the 19th century, Description of Egypt

Tilt angle

It is not possible to accurately determine the original parameters of the pyramid, since its edges and surfaces are currently mostly dismantled and destroyed. This makes it difficult to calculate the exact angle of inclination. In addition, its symmetry itself is not ideal, so deviations in the numbers are observed with different measurements.

Geometric study of ventilation tunnels

A study of the geometry of the Great Pyramid does not provide a clear answer to the question of the original proportions of this structure. It is assumed that the Egyptians had an idea of the “Golden ratio" and the number pi, which were reflected in the proportions of the pyramid: for example, the ratio of height to base is 14/22 (height = 280 cubits, and base = 440 cubits, 280/440 = 14/ 22). For the first time in world history, these quantities were used in the construction of the pyramid at Meidum. However, for pyramids of later eras, these proportions were not used anywhere else, as, for example, some have height-to-base ratios, such as 6/5 (Pink Pyramid), 4/3 (Pyramid of Khafre) or 7/5 (Broken Pyramid).

Some of the theories consider the pyramid to be an astronomical observatory. It is argued that the corridors of the pyramid accurately point towards the “pole star” of that time - Thuban, the ventilation corridors on the south side point to the star Sirius, and on the north side to the star Alnitak.

Internal structure

Cross section of the Cheops pyramid:

The entrance to the pyramid is at an altitude of 15.63 meters on the north side. The entrance is formed by stone slabs laid in the form of an arch, but this is the structure that was inside the pyramid - the true entrance has not been preserved. The true entrance to the pyramid was most likely closed with a stone plug. A description of such a plug can be found in Strabo, and its appearance can also be imagined based on the preserved slab that covered the upper entrance to the Bent Pyramid of Snefru, the father of Cheops. Today, tourists enter the pyramid through a 17-meter gap, which was made 10 meters lower by the Baghdad caliph Abdullah al-Mamun in 820. He hoped to find the pharaoh's countless treasures there, but found there only a layer of dust half a cubit thick.

Inside the Cheops pyramid there are three burial chambers, located one above the other.

Funeral "pit"

Underground Chamber Maps

A 105 m long descending corridor running at an inclination of 26° 26'46 leads to an 8.9 m long horizontal corridor leading to the chamber 5 . Situated below ground level in a limestone bedrock, it remained unfinished. The dimensions of the chamber are 14x8.1 m, it extends from east to west. The height reaches 3.5 m, the ceiling has a large crack. At the southern wall of the chamber there is a well about 3 m deep, from which a narrow manhole (0.7 × 0.7 m in cross-section) stretches in a southern direction for 16 m, ending in a dead end. At the beginning of the 19th century, engineers John Shae Perring and Richard William Howard Vyse cleared the floor of the chamber and dug a well 11.6 m deep, in which they hoped to discover a hidden burial chamber. They were based on the testimony of Herodotus, who claimed that the body of Cheops was located on an island surrounded by a canal in a hidden underground chamber. Their excavations came to nothing. Later studies showed that the chamber was abandoned unfinished, and it was decided to build the burial chambers in the center of the pyramid itself.

Ascending Corridor and Queen's Chambers

From the first third of the descending passage (18 m from the main entrance) upward at the same angle of 26.5°, an ascending passage goes south ( 6 ) about 40 m long, ending at the bottom of the Great Gallery ( 9 ).

At its beginning, the ascending passage contains 3 large cubic granite “plugs”, which from the outside, from the descending passage, were masked by a block of limestone that fell out during the work of al-Mamun. Thus, for the first 3000 years from the construction of the pyramid (including during the era of its active visits in Antiquity), it was believed that there were no other rooms in the Great Pyramid other than the descending passage and the underground chamber. Al-Mamun was unable to break through these plugs and simply hollowed out a bypass to the right of them in the softer limestone. This passage is still in use today. There are two main theories about the traffic jams, one of them is based on the fact that the ascending passage has traffic jams installed at the beginning of construction and thus this passage was sealed by them from the very beginning. The second argues that the current narrowing of the walls was caused by an earthquake, and the plugs were previously located within the Great Gallery and were used to seal the passage only after the funeral of the pharaoh.

An important mystery of this section of the ascending passage is that in the place where the traffic jams are now located, in the full-size, albeit shortened model of the pyramid passages - the so-called test corridors north of the Great Pyramid - there is a junction of not two, but three corridors at once, the third of which is a vertical tunnel. Since no one has yet been able to move the plugs, the question of whether there is a vertical hole above them remains open.

In the middle of the ascending passage, the construction of the walls has a peculiarity: in three places the so-called “frame stones” are installed - that is, the passage, square along the entire length, pierces through three monoliths. The purpose of these stones is unknown. In the area of the frame stones, the walls of the passage have several small niches.

A horizontal corridor 35 m long and 1.75 m high leads to the second burial chamber from the lower part of the Great Gallery in a southerly direction. The walls of this horizontal corridor are made of very large limestone blocks, on which false “seams” are applied, imitating masonry from smaller blocks . Behind the western wall of the passage there are cavities filled with sand. The second chamber is traditionally called the “Queen's Chamber,” although according to the ritual, the wives of the pharaohs were buried in separate small pyramids. The Queen's Chamber, lined with limestone, measures 5.74 meters from east to west and 5.23 meters from north to south; its maximum height is 6.22 meters. There is a high niche in the eastern wall of the chamber.

Grotto, Grand Gallery and Pharaoh's Chambers

Another branch from the lower part of the Great Gallery is a narrow, almost vertical shaft, about 60 m high, leading to the lower part of the descending passage. There is an assumption that it was intended to evacuate workers or priests who were completing the “sealing” of the main passage to the “King’s Chamber.” Approximately in the middle there is a small, most likely natural extension - the “Grotto” (Grotto) of irregular shape, in which several people could fit at most. Grotto ( 12 ) is located at the “junction” of the masonry of the pyramid and a small, about 9 meters high, hill on the limestone plateau lying at the base of the Great Pyramid. The walls of the Grotto are partially reinforced by ancient masonry, and since some of its stones are too large, there is an assumption that the Grotto existed on the Giza plateau as an independent structure long before the construction of the pyramids, and the evacuation shaft itself was built taking into account the location of the Grotto. However, taking into account the fact that the shaft was hollowed out in the already laid masonry, and not laid out, as evidenced by its irregular circular cross-section, the question arises of how the builders managed to accurately reach the Grotto.

The large gallery continues the ascending passage. Its height is 8.53 m, it is rectangular in cross-section, with walls slightly tapering upward (the so-called “false vault”), a high inclined tunnel 46.6 m long. In the middle of the Great Gallery along almost the entire length there is a square recess with a regular cross-section measuring 1 meter wide and 60 cm deep, and on both side protrusions there are 27 pairs of recesses of unknown purpose. The recess ends with the so-called. “Big step” - a high horizontal ledge, a 1x2 meter platform at the end of the Great Gallery, immediately before the hole into the “hallway” - the Antechamber. The platform has a pair of ramp recesses similar to those in the corners near the wall (the 28th and last pair of BG recesses). Through the “hallway” a hole leads into the funeral “Tsar’s Chamber” lined with black granite, where an empty granite sarcophagus is located. The sarcophagus lid is missing. Ventilation shafts have mouths in the “King’s Chamber” on the southern and northern walls at a height of about a meter from the floor level. The mouth of the southern ventilation shaft is severely damaged, the northern one appears intact. The floor, ceiling, and walls of the chamber do not have any decorations or holes or fastening elements of anything dating back to the construction of the pyramid. The ceiling slabs have all burst along the southern wall and are not falling into the room only due to the pressure from the weight of the overlying blocks.

Above the “Tsar’s Chamber” there are five unloading cavities with a total height of 17 m discovered in the 19th century, between which lie monolithic granite slabs about 2 m thick, and above there is a gable roof made of limestone. It is believed that their purpose is to distribute the weight of the overlying layers of the pyramid (about a million tons) to protect the “King's Chamber” from pressure. In these voids, graffiti was discovered, probably left by workers.

Ventilation ducts

So-called “ventilation” channels 20-25 cm wide extend from the “Tsar’s Chamber” and “Queen’s Chamber” in the northern and southern directions (first horizontally, then obliquely upward). At the same time, the channels of the “Tsar’s Chamber,” known since the 17th century, through, they are open both below and above (on the edges of the pyramid), while the lower ends of the channels of the “Queen’s Chamber” are separated from the surface of the wall by about 13 cm; they were discovered by tapping in 1872. The upper ends of the Queen's Chamber shafts do not reach the surface by approximately 12 meters, and are closed by stone Gantenbrink Doors, each with two copper handles. The copper handles were sealed with plaster seals (not preserved, but traces remain). In the southern ventilation shaft, the “door” was discovered in 1993 with the help of the remote-controlled robot “Upout II”; the bend of the northern shaft did not allow Then detect the same “door” in it by this robot. In 2002, using a new modification of the robot, a hole was drilled in the southern “door,” but behind it a small cavity 18 centimeters long and another stone “door” were discovered. What lies next is still unknown. This robot confirmed the presence of a similar “door” at the end of the northern channel, but they did not drill it. In 2010, a new robot was able to insert a serpentine television camera into a drilled hole in the southern “door” and discovered that the copper “handles” on that side of the “door” were designed in the form of neat hinges, and individual red ocher icons were painted on the floor of the “ventilation” shaft. Currently, the most common version is that the purpose of the “ventilation” ducts was of a religious nature and is associated with the Egyptian ideas about the afterlife journey of the soul. And the “door” at the end of the channel is nothing more than a door to the afterlife. That is why it does not reach the surface of the pyramid. At the same time, the shafts of the upper burial chamber have through exits to the outside and inside the room; it is unclear whether this is due to some change in ritual; Since the outer few meters of the pyramid's lining have been destroyed, it is unclear whether there were "Gantenbrink Doors" in the upper shafts. (could have been in a place where the mine was not preserved). In the southern upper shaft there is a so-called “Cheops niches” are strange extensions and grooves that may have contained a “door”. There are no “niches” at all in the northern upper one.

- Oh Osiris, I don’t want to die!

-Who wants it? - Osiris shrugged.

“But I... I’m still a pharaoh!.. Listen,” Cheops whispered, “I will sacrifice one hundred thousand slaves to you.”

1. Just allow me to immortalize my life alone!
- One hundred thousand? And are you sure that they will all die during construction?
- Rest assured. Such a pyramid as I conceived... - Well, if so... Perpetuate it, I don’t mind.
The Pyramid of Cheops
Nobody remembers Cheops alive. Everyone only remembers him when he is dead. He was dead a hundred, a thousand, and three thousand years ago and always, always will be dead - the pyramid immortalized his death.
What is called the first wonder of the world?
Already in ancient times, the pyramids of Giza were considered one of the seven “wonders of the world.” The largest of the pyramids was built by Pharaoh Khufu (2590 - 2568 BC), in Greek his name was Cheops. Currently, the height of the pyramid is 138 m, although originally it was 147 m: the top stones fell during earthquakes. The pyramid is made up of 2.5 million limestone blocks of different sizes, weighing on average 2.5 tons. Initially, it was lined with white sandstone, which was harder than the main blocks, but the lining has not been preserved. At the base of the pyramid lies a square with a side of 230 m, oriented to the cardinal points. According to some legends, the corners of the square symbolize Truth, Reason, Silence and Depth; according to others, the pyramid is based on the four material substances from which the human body is created.

2. The greatest creations of antiquity among the pyramids include only the Pyramid of Cheops, also called the Great Pyramid.

Its height is 146.6 m, which approximately corresponds to a fifty-story skyscraper. The base area is 230x230 m. In such a space, five of the largest cathedrals in the world could easily fit simultaneously: St. Peter's Cathedral in Rome, St. Paul's Cathedral and Westminster Abbey in London, as well as the Florence and Milan cathedrals. From the building stone used for the construction of the Cheops pyramid, it would be possible to build all the churches in Germany created in our millennium. The young pharaoh Cheops gave the order to build the pyramid immediately after the death of his father Snefru. Like all previous pharaohs since the time of Djoser (approximately 2609 -2590 BC), Cheops wanted to be buried after his death in a pyramid.
The ivory statue of Pharaoh Cheops is the only surviving image of the pharaoh. On the head of Cheops is the crown of the Ancient Egyptian kingdom, in his hand is a ceremonial fan.
Like his predecessors, he believed that his pyramid should surpass all other pyramids in size, splendor and luxury. But before the first of the more than two million blocks that made up the pyramid was cut from a quarry on the east bank of the Nile, complex preparatory work was carried out. First, it was necessary to find a suitable site for the construction of the pyramid. The weight of the huge structure is 6,400,000 tons, so the soil had to be strong enough so that the pyramid would not sink into the ground under its own weight. The construction site was chosen south of the modern Egyptian capital Cairo, on a ledge of a plateau in the desert seven kilometers west of the village of Giza. This strong rocky platform was able to support the weight of the pyramid.
First, the surface of the site was leveled. To do this, a waterproof rampart of sand and stones was built around it. In the resulting square, a dense network of small channels intersecting at right angles was cut out, so that the site looked like a huge chessboard. The channels were filled with water, the height of the water level was marked on the side walls, and then the water was drained. The stonemasons cut down everything that protruded above the surface of the water, and the channels were again filled with stone. The base of the pyramid was ready.
Over 4,000 people - artists, architects, stonemasons and other artisans - carried out these preparatory work for about ten years. Only after this could the construction of the pyramid itself begin. According to the Greek historian Herodotus (490 - 425 BC), construction continued for another twenty years, about 100,000 people worked on the construction of the huge tomb of Cheops. Only on radishes, onions and garlic, which were added to the food of construction workers, 1600 talents were spent, i.e. approximately $20 million. Data on the number of workers are questioned by many modern researchers. In their opinion, there would simply not be enough space on the construction site for so many people: more than 8,000 people would not be able to work productively without interfering with each other.
Herodotus, who visited Egypt in 425 BC, wrote: “The method used was to build in steps, or as some call it, in rows or terraces. When the foundation was completed, the blocks for the next row above the foundation were raised from the main level with devices made from short wooden levers; on this first row there was another one that raised the blocks one level higher, so step by step the blocks were raised more and more. Higher and higher. Each row or level had its own set of mechanisms of the same type, which easily moved loads from level to level. The completion of the pyramid began at the top with the highest level, continued down, and ended with the lowest levels closest to the ground."
At the time of the construction of the pyramid, Egypt was a rich country. Every year from the end of June to November, the Nile overflowed its banks and flooded the adjacent fields with its waters, leaving on them a thick layer of silt that turned the dry desert sand into fertile soil. Therefore, in favorable years it was possible to harvest up to three harvests a year - grain, fruits and vegetables. So, from June to November, the peasants could not work in their fields. And they were glad when every year in mid-June the pharaoh’s scribe appeared in their village, compiling lists of those willing to work on the construction of the pyramid.

3. Who worked on the construction of the pyramid?
Almost everyone wanted this work, which means it was not forced labor, but voluntary labor. This was explained by two reasons: each participant in construction received housing, clothing, food and a modest salary during work. Four months later, when the waters of the Nile receded from the fields, the peasants returned to their villages.

In addition, every Egyptian considered it his natural duty and a matter of honor to participate in the construction of the pyramid for the pharaoh. After all, everyone who contributed to the accomplishment of this grandiose task hoped that a piece of the immortality of the god-like pharaoh would touch him too. Therefore, at the end of June, endless streams of peasants flocked to Giza. There they were housed in temporary barracks and grouped into groups of eight. Work could begin. Having sailed on boats to the other side of the Nile, the men headed to the quarry. There they cut down a block of stone, trimmed it using sledgehammers, wedges, saws and drills and obtained a block of the required dimensions - with sides from 80 cm to 1.45 m. Using ropes and levers, each group installed its block on wooden runners and on them she dragged him along the log flooring to the bank of the Nile. The sailboat transported workers and a block weighing up to 7.5 tons to the other side.

4. What job was the most dangerous?
The stone was dragged along roads lined with logs to the construction site. Here came the hardest work, since cranes and other lifting devices had not yet been invented. Along an inclined entrance 20 m wide, built of bricks from Nile silt, runners with a stone block were pulled with the help of ropes and levers to the upper platform of the pyramid under construction. There, workers laid the block in the place indicated by the architect with millimeter precision. The higher the pyramid rose, the longer and steeper the entrance became and the more and more the upper working platform became smaller. Therefore, the work became more and more difficult.
Then came the turn of the most dangerous work: laying the “pyramidon” - an upper block nine meters high, dragged upward along an inclined entrance. We don’t know how many people died doing just this work. So, twenty years later, the construction of the pyramid body was completed, which consists of 128 layers of stone and is four meters higher than Strasbourg Cathedral. By this time, the pyramid looked much the same as it looks now: it was a stepped mountain. However, the work did not end there: the steps were filled with stones, so that the surface of the pyramid became, although not completely smooth, but without protrusions. To complete the work, the four triangular outer edges of the pyramid were lined with slabs of dazzling white limestone. The edges of the slabs were fitted so precisely that it was impossible to insert even a knife blade between them. Even from a distance of several meters, the pyramid gave the impression of a giant monolith. The outer slabs were polished to a mirror finish using the hardest grinding stones. According to eyewitnesses, in the sun or moonlight, the tomb of Cheops sparkled mysteriously, like a huge crystal glowing from within.

5. What's inside the Cheops pyramid?
The Cheops Pyramid is not made entirely of stone. Inside it there is an extensive system of passages, which through a large passage 47 m long, the so-called large gallery, leads to the pharaoh's chamber - a room 10.5 m long, 5.3 m wide and 5.8 m high. It is entirely lined with granite, but not decorated with any ornament. There is a large empty granite sarcophagus without a lid. The sarcophagus was brought here during construction, since it does not go into any of the passages of the pyramid. Such chambers of the pharaohs are found in almost all Egyptian pyramids; they served as the last refuge of the pharaoh.
There are no inscriptions or decorations inside the Cheops pyramid, with the exception of a small portrait in the passage leading to the Queen's chamber. This image resembles a photograph on a stone. On the outer walls of the pyramid there are numerous curvilinear grooves of large and small sizes, in which, at a certain lighting angle, one can discern an image 150 meters high - a portrait of a man, apparently one of the deities of Ancient Egypt. This image is surrounded by other images (the trident of the Atlanteans and Scythians, a bird-plane, plans of stone buildings, pyramid rooms), texts, individual letters, large signs resembling a flower bud, etc. On the northern side of the pyramid there is a portrait of a man and a woman with their heads bowed towards each other. These huge images were painted just a few years before the main pyramid was completed and installed in 2630 BC. top stone.
Inside the Cheops pyramid there are three burial chambers, located one above the other. The construction of the first chamber was not completed. It is carved into the bedrock. To get into it, you need to overcome 120 m of a narrow descending corridor. The first burial chamber is connected to the second by a horizontal corridor 35 m long and 1.75 m high. The second chamber is called the “queen’s chamber,” although according to the ritual the wives of the pharaohs were buried in separate small pyramids.
The queen's chamber is surrounded by legends. A legend is associated with it, according to which the pyramid was the main temple of a certain Supreme Deity, a place where ancient secret religious rites were held. Somewhere in the depths of the pyramid lives an unknown creature with the face of a lion, who holds in his hands the seven keys of Eternity. No one can see it except those who have undergone special rites of preparation and purification. Only to them did the Great Priest reveal the secret Divine Name. A person who owns the secret of the name became equal in magical power to the pyramid itself. The main sacrament of initiation took place in the royal chamber. There, the candidate, tied to a special cross, was placed in a huge sarcophagus. The person accepting initiation was, as it were, in the gap between the material world and the divine world, inaccessible to human consciousness.
From the beginning of the horizontal corridor, another one goes up, about 50 m long and more than 8 m high. At the end of it there is a horizontal passage leading to the pharaoh’s burial chamber, trimmed with granite, in which the sarcophagus is placed. In addition to the burial chambers, voids and ventilation shafts were discovered in the pyramid. However, the purpose of many rooms and various void channels is not fully understood. One of these rooms is a room where on a table there is an open book about the history and achievements of the country during the period of completion of the pyramid.
The purpose of the underground structures at the foot of the Cheops pyramid is also unclear. Some of them were opened at different times. In one of the underground structures in 1954, archaeologists found the oldest ship on Earth - a wooden boat called solar, 43.6 m long, disassembled into 1224 parts. It was built of cedar without a single nail and, as evidenced by the traces of silt preserved on it, before the death of Cheops it was still floating on the Nile.

6. How was the pharaoh buried?
After death, the carefully embalmed body of the ruler was placed in the burial chamber of the pyramid. The internal organs of the deceased were placed in special hermetic vessels, the so-called canopies, which were placed next to the sarcophagus in the burial chamber. So, the mortal remains of the pharaoh found their last earthly refuge in the pyramid, and the “ka” of the deceased left the tomb. “Ka,” according to Egyptian ideas, was considered something like a person’s double, his “second self,” which left the body at the moment of death and could move freely between the earthly and the afterlife. Having left the burial chamber, the “ka” rushed to the top of the pyramid along its outer lining, which was so smooth that no mortal could move on it. The father of the pharaohs, the sun god Ra, was already there in his solar boat, in which the deceased pharaoh began his journey to immortality.
Recently, some scientists have expressed doubt that the Great Pyramid was really the tomb of Pharaoh Cheops. They put forward three arguments in favor of this assumption:
The burial chamber, contrary to the customs of that time, does not have any decorations.
The sarcophagus in which the body of the deceased pharaoh was supposed to rest was only roughly hewn, i.e. not completely ready; the cover is missing.
And finally, two narrow passages through which air from outside penetrates into the burial chamber through small holes in the body of the pyramid. But the dead do not need air - here is another weighty argument in favor of the fact that the Cheops pyramid was not a burial place.
7. Who was the first to penetrate the Cheops pyramid?
The entrance to the Cheops pyramid was originally located on the north side, at the level of the 13th row of granite slabs. It is now closed. You can get inside the pyramid through a hole left by ancient robbers.
For more than 3,500 years, the inside of the Great Pyramid was not disturbed by anyone: all the entrances to it were carefully walled up, and the tomb itself, according to the Egyptians, was guarded by spirits ready to kill anyone who tried to penetrate it.
That is why the robbers appeared here much later. The first person to penetrate inside the Cheops pyramid was Caliph Abdallah al-Mamun (813-833 AD), son of Harun al-Rashid. He dug a tunnel to the burial chamber in the hope of finding treasure there, as in other tombs of the pharaohs. But he found nothing except the droppings of the bats that lived there, the layer of which on the floor and walls reached 28 cm. After this, the interest of robbers and treasure hunters in the Cheops pyramid disappeared. But they were replaced by other robbers. In 1168 after R. Chr. part of Cairo was burned and completely destroyed by the Arabs, who did not want it to fall into the hands of the crusaders. When the Egyptians later began rebuilding their city, they removed the shiny white slabs that covered the outside of the pyramid and used them to build new houses. Even now these slabs can be seen in many mosques in the old part of the city. All that remains of the former pyramid is the stepped building - this is how it now appears before the admiring eyes of tourists. Along with the cladding, the pyramid also lost its top, the pyramidon, and the upper layers of masonry. Therefore, now its height is no longer 144.6 m, but 137.2 m. Today, the top of the pyramid is a square with sides of approximately 10 m. This site in 1842 became the venue for unusual festivities. The Prussian king Frederick William IV, known for his love of art, sent an expedition to the Nile Valley led by archaeologist Richard Lepsius with the aim of acquiring ancient Egyptian art objects and other exhibits for the Egyptian Museum being created in Berlin (it was opened in 1855).

Powerful, surrounded by mystery... - this is how the Cheops pyramid stood for 4500 years

Therefore, this article will present only the basic general facts and figures relating to the Great Pyramid as a whole.

Date of construction and geometric dimensions

According to generally accepted opinion, the Great Pyramid was built in the 2560-2580s BC as a tomb for the reigning pharaoh of the IV dynasty, Cheops (Khufu). Despite some difficulties in explaining the possibility of its construction in the required time frame using the technology available at that time, this version is nevertheless considered the main one and has quite numerous confirmations in the form of inscriptions discovered inside the Pyramid and the Pit of the Solar Boat with it.

The Pyramid of Cheops is the largest of the Egyptian pyramids.

Height (today): ≈ 138.75 m
Height (original): ≈ 146.5 m
Angle: 51° 50"
Side length (original): 230.33 m (calculated) or about 440 Royal cubits
Side length (currently): about 225 m
The length of the sides of the base of the pyramid: south - 230.454 m; north - 230.253 m; west - 230.357 m; east - 230.394 m.
Foundation area (initially): ≈ 53,000 m² (5.3 ha)
Area of the pyramid: (initially) ≈ 85,500 m²
Perimeter: 922 m.
Total volume of the pyramid without deducting the cavities inside the pyramid (initially): ≈ 2.58 million m³
Total volume of the pyramid, after subtracting all known cavities (initially): 2.50 million m³
The average size of the observed stone blocks of rough masonry: 1.27 m in width and depth, 71 cm in height (according to Petrie)
Average weight of rough masonry stone blocks: 2.5 t
The heaviest stone block of rough masonry: 15 t
Heaviest stone block (known; granite; above the entrance to the King's Chamber): 90 t
Number of blocks: about 2.5 million (provided that the pyramid is not a backfill type)
Estimated total weight of the pyramid: about 6.25 million tons (possibly about 6 million tons according to microgravimetry)
The base of the pyramid rests on a natural rocky elevation in the center (in the Grotto area) more than 9 m high.
Materials used in construction (from known ones): limestone from the Giza Plateau - rough masonry, Tour white limestone - internal walls, ventilation shafts and external cladding, Aswan granite - Antechamber, King's Chamber, unloading chambers (partially), plugs; Sinai - sarcophagus. Quartz sand was also found inside.
The pyramidion of the pyramid was not found, nor were its mounting stones.
The True Entrance is located traditionally, i.e., on the north side. He is the only one known.

Difference in thickness of pyramid masonry layers

Despite the fact that the pyramid is built in layers, the thickness of the layers is different and varies from 60 cm to one and a half meters.

The reasons for this are not exactly known, there are several hypotheses, the simplest one says that large blocks were laid in eras when there was an excess amount of labor for laying layers of rough masonry. Which may be connected, for example, with its release after the completion of a certain labor-intensive stage in the construction of some complex internal infrastructure or a season for the procurement of blocks, etc. The scheme requires careful analysis.

Current state of affairs and appearance after the disappearance of the cladding

The Great Pyramid now has edges concave inward. This often gives rise to various theories and speculations, but it should be remembered that the structure has lost several meters of cladding on each side, and the nature of its looting for stone does not give reason to believe that the original faces were not flat.

Perhaps the observed picture is simply a consequence of the most profitable extraction of stone.

Question about using the pyramid for its intended purpose

Since ancient times, the question has been acutely raised: was the Cheops pyramid used for its intended purpose? There is still no clear answer to this question. On the one hand, there is almost complete confidence that the pyramid was completely completed by the builders. On the other hand, what we see inside it, for example, a sarcophagus in the King’s Chamber that is clearly not of the best quality, an unfinished floor in the Queen’s Chamber, or a picture of complete incompleteness in the Underground Chamber - everything suggests that the pharaoh in these famous premises could hardly have been buried at all. Herodotus also claimed that Cheops was buried in another place, on an island surrounded on all sides by water. On the third hand, traces of obvious hacking of the plugs and dampers of the Antechamber indicate that for some reason the pyramid was carefully sealed. The official point of view of science on this matter suggests that the burglars visited the pyramid no later than the first 500-600 years from the moment of its construction. But what they found, who they were and whether they found anything at all is completely unknown. In the volume of the Great Pyramid, the volume of all known and explored rooms is less than 1 percent, and it is already known that in addition to the explored ones, there are several unknown sealed rooms in it.

Blocks and Quarries

Egyptologists believe that the Pyramids of Giza were built from natural stone, which was quarried from three quarries. The actual construction of the pyramids is made of nummulitic limestone of the Mokattam formation. The quarries were located in close proximity to the pyramids. The lower parts of the pyramids of Khafre and Mikerin were lined with granite from the Aswan quarry, which is located in Southern Egypt at a distance of 934 kilometers along the Nile (700 kilometers in a straight line). Several rows of granite cladding have been preserved at the pyramid of Mikerin. The middle and upper parts of the two large pyramids were lined with limestone from the Tours quarry, which is located on the eastern bank of the Nile south of Cairo at a distance of 13-17 kilometers from the pyramids. The number of pyramid facing blocks (granite and limestone) that have reached us is relatively small. Therefore, we can simply agree that stone from the Tours and Aswan quarries was used in the construction of the pyramids. The opinion that the pyramids were built from nummulitic limestone does not fully correspond to reality. The lower rows of the pyramids are made of hard limestone from the Moqattam formation. Higher up, blocks of soft limestone, which lack nummulites, predominate. It is fundamentally. That is, when describing the blocks of pyramids in specialized literature, it seems to remain “behind the scenes” that most of them are carved out of soft limestone.

The bottom rows of the pyramids (approximately 1-7/10 rows) are made of blocks cut from solid limestone. The first row of the Cheops pyramid (thickness 1.5 m) is carved from a layer of strong limestone, which has the greatest thickness - 1.5 m. The upper rows of the pyramids are dominated by blocks cut from soft limestone (or cast blocks indistinguishable from them - this statement requires evidence, Supervisor 03:05, 22 May 2011 (UTC)). When developing the quarry, it was necessary to fulfill one condition: the time elapsed from the opening of soft limestones to the cutting of building blocks from them should be minimal. That is, soft limestones had to be cut into blocks before they hardened from contact with air. In addition, after cutting the soft limestone blocks, it took some time for them to harden and not crumble during transportation. The cyclical nature of quarry development meets these requirements. Its site was being developed, the area of which was approximately 1.5 times larger than the area of the row of blocks where the construction of the pyramid was stopped. The blocks were cut from layers of hard and soft limestone and stored “layer by layer,” that is, according to their vertical dimensions. After all the limestone had been removed from the area, its laying into the body of the pyramid began. The order of laying blocks of different thicknesses (and, accordingly, different weights) was determined by the ratio of labor costs for lifting them. This ensured that the rows of blocks were ranked according to their thickness.

Base of the pyramid

The rocky base of the Cheops pyramid, according to modern calculations, occupies 23% of the volume of the pyramid, or about 600,000 cubic meters. The minimum figures were obtained by determining the height of the rock in terms of an average level of 12.5 meters. But the authors of the study do not exclude the possibility of using an average height of 20 meters. In any case new geological exploration work is required to clarify these data. A revision of most old works with calculations of the stone used during construction is also required. In addition, there are estimates of 10-12% of the volume of the pyramid, which is occupied by the mortar holding the blocks together.

The directions to the north of the side faces were kept so precisely that due to the sphericity of the Earth and the colossal size of the Pyramid, its northern side turned out to be 20 cm shorter than the southern one. (the exact dimensions of the pyramid are known from the preserved pits of the supporting corner stones)
