The Pyramid of Cheops is a monumental structure fraught with many facts and mysteries. Here are fifteen of them, most of which you've probably never heard of. We will not touch upon myths and legends - the most Interesting Facts about the pyramid of Cheops based on real research

For about three thousand years, the Cheops pyramid was the tallest creation of human hands in the world. It was not until 1311 that Lincoln was built Cathedral, this building became the second tallest.
The construction of the pyramid took 20 years. It remains a mystery how such a monumental structure was erected so quickly with an archaic level of construction knowledge and disgusting logistics. The construction of other burial structures took much longer - from 50 to 200 years.
Pyramid of Cheops - an accurate compass. The edges of the Cheops pyramid are oriented to the cardinal points. The error is only 5 degrees. Such compliance is not easy to achieve even with the modern level of construction development. At first the correspondence was perfect, and only the constant movement of the Earth's north pole allowed a slight deviation to appear.
The Pyramids of Cheops were visible from space. The construction of the structure took more than 2.2 million blocks of limestone. This loose building material would certainly have deteriorated over time if it had not been covered with granite cladding. There are no gaps between the cladding slabs; they are perfectly polished. When the lining was in place, the sunlight reflected from it was so bright that the structure of Cheops was probably visible from space.
Constant temperature inside the building - 20⁰С. The Cheops Pyramid is a giant isothermal chamber - when the air temperature outside reaches 50⁰C, in this structure it does not rise above 20⁰C.
There was never a pharaoh's burial in the Cheops pyramid. Many consider the Cheops pyramid to be the burial place of the pharaoh. In fact, the remains of the rulers were buried in the Valley of the Kings. And inside the thick walls were stored necessary things, which, according to the ancient Egyptians, helped the ruler in the afterlife.
Delivery of building materials was carried out in a way unknown to science. The methods used to build stone monsters can be explained high level construction organization. Huge stones were carved in quarries located on Mediterranean coast. It remains a mystery how they were transported hundreds of kilometers from the quarry to the construction site - the condition of the horse-drawn and water transport did not allow moving heavy stones over significant distances.
The Pyramid of Cheops was built by free people. This structure was built by free architects and masons who came to the construction site from all over the Egyptian state. It is possible that slaves were used as labor, but there is evidence that most of the workers were free and built for money. By the way, this ancient temple about 100,000 people died.
The composition of the solution that fastened the blocks of the pyramid has not yet been solved. Lime and granite slabs are held together with a mysterious mortar that has no modern analogues. Grasping material was developed in the early Predynastic period. After cooling, the solution became stronger than stone and was not afraid of heat, dry winds, or time. Scientists do not know how and from what it was prepared.
Even a blade cannot be inserted between the cladding of the pyramid.. The skill of the builders is admirable, who were able to fit the cladding so tightly that it is impossible to even insert a knife blade between the cladding slabs. Few modern buildings can boast of this quality of laying building materials.
Pi and other oddities. The existence of the pyramid is confirmed by the fact that the Egyptians knew about the “golden ratio”, the number π and other constants used in geometry and architecture. Scientific evidence These formulas were developed by ancient Greek mathematicians a thousand years later.
The inside walls of the Cheops pyramid are not covered with drawings or hieroglyphs. The walls of the corridors of the Cheops pyramid are empty - there are no numerous inscriptions and drawings on them. Egyptologists have found several dozen cartouches and inscriptions indicating the names of the builders who took part in the construction of the tomb. There were inscriptions of a technical nature that shed light on the technology of construction of this religious building.
The ancient Greeks and Arabs knew about the Cheops pyramid. The first researchers of Egyptian antiquities were the Greeks. The mathematician Thales knew very well about the existence of the Cheops structure, and even measured the length of its shadow. The Arab scientist Abdullah Al Mamun attempted to penetrate the forbidden walls. He managed to do this, but did not discover any treasures or secret knowledge.
Napoleon was interested in ancient structures and during the Egyptian campaign he wished to visit the tomb of Cheops. But after the first minutes spent inside the ancient building, Napoleon felt so bad that he never returned to the issue of visiting ancient tombs. But he kept scientists interested in discovering Egyptian secrets and subsidized several scientific expeditions.
The birthday of the Cheops pyramid is a national holiday in Egypt. Modern Egyptians receive a good income from tourists visiting ancient monuments. They even approved the birthday of the Cheops pyramid - it is celebrated on August 23. Despite the fact that this date is very controversial, on this day the Egyptians celebrate the beginning of the construction of the tomb of Cheops.

- 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
The Pyramid of Mikerin, which is even smaller, is located 200 meters from the Pyramid of Khafre. Its height is 62 meters, and the length of the sides is 108 meters. But the most famous Egyptian monument in the world after the Pyramid of Cheops is the figure of the Sphinx, vigilantly guarding the city of the dead.
The three pyramids are part of a complex that also consists of several temples, small pyramids, and tombs of priests and officials.
Smaller in size and located south of the pyramid were probably intended for the wives of rulers and remained unfinished.

2. How was the Cheops pyramid built?

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 could easily fit simultaneously largest cathedrals world: St. Peter's Basilica 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 Snofru. 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 at east coast Nila, 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 was cut out, intersecting at right angles, 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 construction participant 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. 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 body of the pyramid was completed, which consists of 128 layers of stone and is four meters higher 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 faces 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 last refuge 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 external walls pyramids 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 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 lies 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 in different time. 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 into immortality.
IN Lately Some scientists doubt that Great Pyramid really was 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 interior 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's why the robbers came 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).

Age of the pyramid

Architect Great Pyramid believed to be Hemiun, 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 which pyramid he was 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 Dahshur (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 an unevenness - a concavity in 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.

Tilt angle

It is not possible to accurately determine the initial parameters of the pyramid, since its edges and surfaces are currently for the most part 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 about the “Golden ratio" and the number pi, which were reflected in the proportions of the pyramid: thus, 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 get inside 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.

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 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), an ascending passage goes south at the same angle of 26.5° ( 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 design of the walls has a peculiarity: in three places the so-called “frame stones” are installed - that is, the passage, square along its 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; her maximum height 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 of it 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 about 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, with the help new modification The robot drilled a hole 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.

History of research

The Pyramid of Cheops was built around 2600 BC.

The pyramids are shrouded in mystery to this day. Many scientists have devoted their entire lives to unraveling the great construction and purpose of these majestic buildings. However, several thousand years, from the first research of Herodotus to the present day, have not brought the expected success. The main questions remained unanswered: who? When? For what? We will tell you about the most reliable assumptions and versions collected by the best scientists over several centuries and related to the history of the Egyptian pyramids.

Already in ancient times, the pyramids were considered one of the main wonders of the world! Their number was about 100, located along the banks of the Nile River. If you look at all the pyramids from above, their location is similar to a star map. The largest, main pyramids are located in Giza. The world-famous sphinxes, as well as temples and tombs of the pharaohs, are also located here. A very important factor of the pyramids is that all their faces are clearly located along the magnetic poles of the Earth! You probably already know name of three main pyramids? If not, then be sure to remember - the pyramid of Cheops, Mikerin and Khafre.

The largest pyramid, Cheops, was erected by Khufu, who at that time was a pharaoh. The estimated, most accurate date of construction is 2590 BC. The height of the pyramid is more than 146 meters, the length of each side is more than 241 m. The faces are located in the cardinal directions with amazing accuracy, the angle of inclination is 52 degrees. The Pyramid of Cheops covers an area of 5.4 hectares, the base is aligned relative to the horizon with an accuracy of 3 centimeters. The pyramid consists of more than 2,350,000 stone blocks, each weighing about two and a half tons! The pyramid was originally covered with a white sandstone casing to give it an accurate shape and long-lasting durability. Unfortunately, the cladding has not survived to this day.

The entrance to the pyramid is at an altitude of 14 meters. There are no decorations, inscriptions or drawings inside. Therefore, there are three chambers, the lower of which is located at a depth of 30 meters relative to the ground. The room is hewn out of the rock, in order to get to it you need to overcome 120 meters of a narrow corridor (1.1x1.0) at an angle of 27 degrees. After this, the remaining 9 meters, the angle changes to zero relative to the horizon. The tunnel ends with a burial chamber measuring (8.0 x 14.0 x 3.0).

Now the passage to the lower tier is closed, but you can go along the stairs, and then along the 40-meter corridor that leads to the queen’s chamber. The room with dimensions (5.5x5.2x6.3) is located clearly in the middle, at a height of 20 meters from the ground. There are two ventilation shafts in the walls, directed exactly north and south, but not facing the street.

Even higher is the “Grand Gallery” - a corridor more than 48 meters long, with a ceiling height of 8.4 m and an inclination angle of 26 degrees. The walls are lined with polished lime slabs in eight layers. At the end of the corridor there is the main room - the tomb of the pharaoh with dimensions (10.5x5.3x5.8). The chamber is lined with black Aswan granite, each block of which weighs at least thirty tons! Moreover, all the blocks are so well polished and adjusted that even the thinnest knife blade cannot pass between them. The ceiling consists of 9 monoliths, each weighing more than 400 tons. Above them are unloading chambers 17 meters high, designed to preserve the peace of the pharaoh. A gable roof was built above them, made of huge blocks that bear the weight of more than a million tons! We also note that the pharaoh’s sarcophagus is much wider than the entrance to the chamber, and most likely it was hewn right here, from a large block of granite.

There are also ventilation chambers (0.2x0.2) with the exact north-south direction, but unlike the queen’s chamber, here they go outside. In 817, Caliph Mamun was able to enter the tomb of the pharaoh, but found only an empty sarcophagus there; the remains of Cheops were never discovered.

The finds near the pyramid are also interesting. For example, in 1953, during excavations, the oldest ship in the world was discovered - a wooden boat, about 44 meters long, built without nails from cedar. Traces of silt were found on the wooden elements of which, which means that at one time the boat was used for its intended purpose. Ancient writings claim that the pyramid was surrounded by a stone wall, the height of which was 10 meters and the width of 3 meters. There were two temples located nearby - the upper and the lower. The upper one was east of the pyramid, built from Turkish limestone and contained about 40 granite pillars. The lower temple was used for the first part of the funeral ceremony.

The essence of the entire system of buildings was most likely this - initially the remains of the pharaoh were delivered along the Nile to the lower temple, where, after the necessary preparations, they were sent to the upper temple along a long connecting corridor. In the upper temple, among many columns, funeral services and prayers for the repose of the pharaoh took place. After this, the body was taken to the lower chamber of the pyramid, where the pharaoh was carefully walled up. On the four sides of the pyramid, walled up in the rocks, there were four boats intended for travel in the afterlife. The main pyramid accompanied by three small companion pyramids (base length 49 m), located in the same way as the upper temple, in the east. Moreover, each subsequent one (from north to south) is smaller than the previous one. It is believed that the companion pyramids were intended for the wives of the pharaoh.

There are other theories about the purpose of the pyramids. In those distant times, the pharaohs were ruled by a group of priests who possessed unearthly knowledge. This was a separate caste of people who called themselves the chosen ones. They knew mathematics, medicine, astronomy and other sciences very well. The level of education of the priests was many times higher than our understanding of the world. To the common man this knowledge was not available. The priests chose their students themselves, initiating and teaching them in underground rooms located under the pyramids. The teachings assumed a connection with the universe and awareness of the essence of earthly existence. After this, the student was tested in the labyrinths of the pyramids, then in a secret sanctuary, under pain of death, they sought complete obedience and an oath of non-disclosure of secrets. The priests could predict the future thanks to their connection with the higher powers of the universe. Let’s make a reservation right away: later the chosen ones disappeared due to the so-called loss of communication.

Modern scientists have found many confirmations of this - the 33-year duration of Christ, the date of the beginning of the Second World War. Back in 1964, Charles Smith suggested that the pyramids store information for understanding prophecies from the Bible from the beginning of time until the second coming of God.

In 1994, using computer modeling, a discovery was made that explained the location of the three main pyramids, which exactly corresponded to the position of the three stars of Orion's belt, which at that time just crossed the Giza meridian. If this assumption is correct, then the age of the pyramids can be increased to 10,400 BC! The same Sphinx is a confirmation of this theory, because its gaze is directed precisely to the point where this constellation was located.

With the help of modern equipment, hidden tunnels were discovered under the sphinx itself, which, according to legend, should have led to a chamber containing a capsule with a message for all humanity. Indeed, the chamber was found; it contained a sarcophagus made of black granite; unfortunately, it turned out to be empty. Therefore, on the walls of the tunnel leading to the chamber, drawings were discovered that represent predictions of the future of humanity. From there it became known that our civilization would face a series of cosmic cataclysms that would terrorize the “Earth” for several millennia. However, the priests will appear on our planet again and will find a way to salvation by mastering space and restoring a civilization based on the laws of existence.

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. .

First mention of the pyramid

Appearance

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.

Statistical data

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

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.

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.

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: thus, the ratio of the height to half the perimeter of the base is 14/22 (height = 280 cubits, and the base = 220 cubits, semi-perimeter of the base = 2 ×220 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).

Internal structure

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

Ascending Corridor and Queen's Chambers

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 previous approximately 3 thousand years it was believed that there were no 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.

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.

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 these channels do not reach the surface by about 12 meters. The upper ends of the channels of the Queen's Chamber 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, a “door” was discovered in 1993 with the help of a remote-controlled robot “Upout II”; the bend of the northern shaft did not allow this robot to detect the same “door” in it. 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.
