Big pyramid. The Mystery of the Egyptian Pyramids

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 secret.

Despite the fact that the most great 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 dimensions of the Cheops pyramid are surprising even modern man. 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 a rising Large gallery. 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 hard, 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 ideal proportions Great Pyramid in 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.

The ancient Greek historian Herodotus says that Cheops forced the entire Egyptian people to work on the construction of the pyramid, dividing them into two parts. He ordered those who were included in the first group to start delivering blocks from quarries in the Arabian mountains to the banks of the Nile. The rest were required to transport the blocks to the foot of the Libyan mountains. 100,000 people were constantly working. Over ten years of hard work, a road was built along which the blocks were delivered to the river. Herodotus believes that building the road was no less difficult a task than building the pyramid itself. And we believe him. This road was paved with polished stone slabs decorated with carvings. It took another twenty years to build the pyramid with all the underground structures and chambers. Imagine, even with modern machines and mechanisms, building such a huge structure would not be easy. Therefore, construction took away the strength of the entire people. But the ancient Egyptians, mind you, considered this a very honorable, sacred and godly thing for themselves. In addition, for four months a year, during the Nile flood, from mid-July to mid-November, all men could work at the construction site while their fields and gardens were flooded with water. When the river returned to its course in early November and sowing time arrived, the peasants went home. Of course, the hardest work was performed by slaves, who were captured and turned into draft animals. The more the pharaoh fought, the more captives there were. And four thousand specialists were constantly working at the construction site: architects, engineers, artists, stonemasons. It was they who designed the temples, secret passages in the pyramid, and painted the walls. How did they manage to perform such miracles?
I'll try to answer you.
The pyramids were built using muscle power. The builders' tools were made of stone and copper. At that time people did not yet know steel and iron. But they knew how to perfectly process stones and make tools from them. For example, knives of that time were as sharp as razors today. The hammers were heavy, like sledgehammers, and small, for light, precise blows. An adze, a chisel, a chisel, a dolerite ball, a saw, a drill, a whetstone, a trowel, a plumb line, a square-level, and a cross-level were also used by Egyptian builders.
A rock was chosen for the base of the pyramid. A layer of sand was removed and underground structures were built. The site on which the pyramid would stand was surrounded by a rampart of sand and stones. A dense network of small channels was punched through the rocky ground and filled with water. The water level was marked on the walls of the canals, then the water was drained, irregularities were removed and the canals were filled up. A strictly horizontal surface remained. Amazingly accurate method. The southeastern corner of the Cheops pyramid is only 2 cm higher than the northwestern one.
Difficult work fell to experienced stonemasons. They were the ones who cut blocks out of the rock. The boundaries of the future block were first marked in the rock, and then a deep ditch was hollowed out along them, and wedges of dry wood were driven into it and doused with water. The tree swelled, increased in volume, the crack expanded and, in the end, the monolith separated from the rock. There was another way. A fire was lit along a line drawn in the rock. When the stone became hot, the flame was quickly poured with water, and thus the same result was obtained. In addition, they used balls made of dolerite, a hard green stone. They beat them along the intended dividing line until the block was separated. The stone block was then worked on site with tools made of stone, copper and wood. The processed block weighed on average 2.5 tons, and the heaviest was 15 tons! Scientists have calculated that total weight pyramids - 5.7 million tons.
The hardest work went to those who moved the stone blocks. These people worked in teams of 8-10 people. Workers hoisted the block onto a sled-like stand, tied it with thick ropes made of papyrus, and dragged it to the construction site. Behind them, the next brigade approached the rock. The stonemasons rolled off one block after another and the traffic on the road never stopped.

It is clear that at the beginning of construction, lifting the blocks was not as difficult as over time: the height increased, and then the Egyptians built an inclined embankment of sand, brick and stone around the pyramid at an elevation angle of 15 degrees. Stone blocks were dragged along this embankment on the same sleds, and in order to reduce the friction force, the track was constantly watered. The blocks were then pulled into place using wooden levers.

There was even more work with the slabs that went into cladding the pyramid. The quarries where white limestone was mined were located on the opposite bank of the Nile. The slabs had to be transported across the river to sailing ships. A canal was dug for ships from the Nile to the construction site. Before covering the walls of the pyramid, the slabs were ground and polished for a long time to a mirror shine.
The quality of work of ancient builders is simply amazing! Imagine that the discrepancies between the horizontal and vertical lines of the pyramid do not exceed the width of your thumb. The stones were fitted so tightly to each other that you couldn’t even put a needle between them.
How do you think they lowered the stone sarcophagus? In the burial chamber, a place for it was fenced off with a stone wall and filled to the top with sand. Then they placed the sarcophagus on the sand, dismantled the wall, and raked out the sand.

Initially, the Cheops pyramid had a height of 147 meters. Now its height is 137 meters. Previously, it had an eight-meter top covered with gold, and now there is a platform on its top. During the Second World War, it housed a British air defense post. And the golden top? Where is she? Whether it collapsed or was stolen, no one knows. The mirror cladding was removed by medieval vandals. True, they believed that it was much more important to use it to build new palaces!
Each side of the square base of the pyramid is 233 meters, the area is more than 50,000 square meters. meters. The pyramid consists of 2,300,000 cubic blocks.
The Moscow Cathedral of Christ the Savior, or St. Isaac's Cathedral in St. Petersburg could easily fit inside the Cheops pyramid. Less of it and Winter Palace in St. Petersburg, and Escorial in Spain, and Buckingham Palace in London.
Do you want to know what is inside the Cheops pyramid? Who was the first to look into it, after centuries and centuries? To be continued.

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 time when construction of the pyramid began 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 Egyptian pyramids, yet Pharaoh Snofru 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 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 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 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; 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 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 that lies at the base 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 discovered in the 19th century. total height 17 m, between which lie monolithic granite slabs about 2 m thick, and above there is a gable limestone ceiling. 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

From the "King's Chamber" and "Queen's Chamber" in the northern and south directions(first horizontally, then obliquely upward) the so-called “ventilation” channels 20-25 cm wide extend off. At the same time, the channels of the “Tsar’s Chamber”, known since the 17th century, are end-to-end, they are open both below and above (on the edges of the pyramid), then As 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, 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 afterworld. 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.

) and Heliopolis millennia before the founding of Cairo. For over three thousand years (before the construction of the cathedral in Lincoln, England, ca. 1300)

The Great Pyramid was the tallest building on Earth. Since 1979, like many other pyramids of the complex " Memphis and its necropolises - the pyramid area from Giza to Dahshur", is a part World Heritage UNESCO.

Age of the pyramid

unknown, Public Domain

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

Appearance

Despite the fact that the Cheops pyramid is the tallest and most voluminous of all the Egyptian pyramids, Pharaoh Snofru still built pyramids in Meidum and Dakhshut ( Bent pyramid and ), the total mass of which is estimated at 8.4 million tons.

In 1168, the Arabs sacked and burned Cairo. Residents of Cairo removed the cladding from the pyramid in order to build new houses.

Concavity of the sides

Franck Monnier, Public Domain

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.

Vivant Denon, Dominique, Public Domain

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.

In the literature on Egyptology, Peter Janosi, Mark Lehner, Miroslav Werner, Zahi Hawass, Alberto Scigliotti came to the same results in measurements, who believe that the length of the sides can be from 230.33 to 230.37 m. Knowing the length of the side and the angle at the base, they calculated the height of the pyramid - from 146.59 to 146.60 m. The slope of the pyramid is 51° 50", which corresponds to a seked (ancient Egyptian unit of measurement of slope, which is defined as the ratio of half the base to the height) of 5 ½ palms. Taking into account the fact that in one cubit (cubit) there are 7 palms, it turns out that with such a chosen seked, the double ratio of the base to the height is equal to 22/7, a well-known approximation of the number pi from ancient times, which, apparently, happened by chance, since other pyramids were chosen other meanings for seked.

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 Section” 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 values 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 astronomical observatory. It is argued that the corridors of the pyramid accurately point towards the “polar star” of that time - Thuban, the ventilation corridors on the south side - to the star Sirius, and on the north side - to the star Alnitak.

Internal structure

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

Funeral "pit"

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

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.

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

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.

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 found, 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 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, 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 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. Pyramid of Queen Meritites (G1b)

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 m³/1.147 m³ = 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

History of research

Recent Research

There is a version that tries to explain the precise fit of individual blocks during the construction of the pyramid by the fact that the blocks were created from a concrete-like material by gradually raising the formwork and making the blocks on the spot - hence the precision of the fit. This version was proposed by the French chemist, Professor J. Davidovits. Professor Davidovits in the mid-twentieth century developed a method for creating so-called geopolymer concrete. Davidovits suggested that his discovery might have been known to the creators of the pyramids. Subsequent studies refuted this theory.

There are also non-scientific works on the pyramids by some researchers, such as Erich von Däniken and Christopher Dunn (The Mystery of the Ancient Egyptian Machines, 1984), based on outdated information from Sir William Flinders Petrie from the book The Pyramids and Temples of Giza (1883).

Around the pyramid

Pharaoh's boats

Near the pyramids, seven pits with real ancient Egyptian boats, dismantled into pieces, were discovered.

The first of these ships, called "" or " Solar boats", was discovered in 1954 by Egyptian architect Kamal el-Mallah and archaeologist Zaki Nour.

The boat was made of cedar and did not have a single trace of nails for fastening the elements. The boat consisted of 1224 parts; they were assembled by restorer Ahmed Youssef Mustafa only in 1968.

The dimensions of the boat are: length - 43.3 m, width - 5.6 m, and draft - 1.50 m. A museum of this boat is open on the south side of the Cheops pyramid.

Of course, everyone knows where the Cheops pyramid is located. After all, this is one of the most outstanding monuments not only of Egypt, but of the entire planet. And despite the achievements of modern science, the secrets of the Cheops pyramid are still unrevealed. This is one of the reasons why this huge structure attracts numerous tourists, as well as the fact that it is the only wonder of the world that has survived to this day.

This place really has some special magnetism. And even the numerous souvenir sellers and camel drivers who want to make money from curious tourists do not spoil the overall impression. Looking ahead, I will say that the Cheops Pyramid inside is not as stunning as the outside. And if you decide to save money on an “internal” excursion, you won’t lose much. Moreover, I would not recommend going inside for people with claustrophobia, breathing problems or heart problems. The corridors here are quite narrow, and the air is heavy and stuffy, despite the presence of ventilation ducts. By the way, excursion tours are often very intense and do not allow time to get acquainted with the pyramidal structures inside. Therefore, be sure to clarify this point in advance if you still decide to come into contact with the secret from the inside.

History of construction

The most famous pyramidal structure owes its “birth” to Pharaoh Khufu, who ruled Egypt for at least 27 years. According to legend, a huge amount of money was spent on the creation of this great monument, which led to the weakening of the state. Scientists do not yet have a consensus on how true this is. But it is clear that a lot of resources were spent. After all, the original height of the Cheops pyramid was 146.6 meters. But what is noteworthy is that it looks slightly lower than the neighboring building. And not only because she “lost” the top. The son of Cheops, building his pyramid, cheated a little by choosing a place 10 meters higher.

There are many versions of how the Cheops pyramid was built, consisting of 2.3 million stone blocks. Their total weight is approximately 6.5 million tons. The stone blocks are carefully fitted to each other and held together with a special compound - pink gypsum “milk”. The walls have a slope of 52 degrees and embody the number "pi". This giant is located on an area of 5 hectares. The diagram of the Cheops pyramid clearly demonstrates that inside it is practically a monolith, in which there are only a few corridors, halls and ventilation ducts. To avoid theft, the ancient Egyptians placed special mechanisms inside. But the traps of the Cheops pyramid, religious prohibitions and other tricks did not protect the structure from robbers.

There is also no exact information about how old the Cheops pyramid is. Its age is estimated at only approximately 4.5 thousand years. But some researchers believe that the monument could have been erected much earlier - back in the 11th millennium BC, and that representatives of extraterrestrial civilizations were involved in the construction.

There are many legends about this building. But I also picked Interesting Facts about the Cheops pyramid, confirmed by scientific research. Among them are those that still remain little known. And if you have never been here on an excursion, then you are unlikely to know that:

For almost three thousand years, the Cheops pyramid was the tallest structure in the world. She gave the “Palm of Championship” only in 1311 - at that time construction was completed in Lincoln Cathedral. Sometimes the Eiffel Tower, built at the end of the 19th century, is mistakenly called the new record holder. In fact, before it there were structures higher than the Cheops pyramid. This is predominantly temple buildings, as well as the Washington Memorial.
Many consider the pyramid to be the tomb of a pharaoh. But this is a misconception, since the Egyptian ruler was buried in the Valley of the Kings, and his body was never inside the structure. But still there is a direct connection with the pharaoh. The pyramid functionally played the role of a kind of “suitcase”. Within its walls are many things that, according to the ancient Egyptians, were necessary for a royal person in the afterlife.
For a long time it was believed that the pyramids were built by slaves. But as modern researchers have proven, free residents were employed in construction Ancient Egypt who also have high professional qualifications. The dimensions and proportions of the Cheops pyramid are perfectly calculated, and the structure was built with impeccable precision.
The Pyramid of Cheops in Egypt was first mentioned in writing in the works of Herodotus. The author describes his own impressions of visiting this religious building and shares the information he received from local priests. This work is dated 440 BC. However, Herodotus was unable to obtain any valuable information, except for some geometric data.
The Pyramid of Cheops has its own “birthday.” The Egyptians celebrate it on August 23, and this day is national holiday. However, this holiday appeared in Egypt quite recently - only in 2009, and has only a tentative relationship to the exact date of the start of construction. This hypothesis was put forward by scientists from Cambridge.

But, nevertheless, too many tourists gather here on this day, and if you want to explore the main Egyptian attraction in a relaxed atmosphere, do not plan an excursion for this day. There are also other nuances that are useful to know if you are going to get to know this wonder of the world with your own eyes.

Helpful information

The Pyramid of Cheops on the map is located on the left and slightly south of Cairo, in Giza. It is from the Egyptian capital that it is most convenient to get to this pyramid complex, where, in addition to the famous tomb of Khufu, you will also see the pyramids of the son and grandson of the pharaoh (Khephren and Mikerin), which are slightly lower. This is the best preserved pyramidal complex in the entire country. The journey from Cairo takes about 20 minutes. Excursion tour can be purchased both directly in the capital and in any of the resorts. The road from Hugarda is approximately 5-6 hours by bus, from Sherm al-Sheikh - from 7 to 8 hours.

When buying excursions from these cities, do not focus on the cheapest offers - there is a risk of ending up in an uncomfortable bus without air conditioning, which, given the high Egyptian temperatures, can ruin the entire impression of the excursion.
Entrance to the territory is paid (80 and 40 EGP for adults and children, respectively). Entrance fee is paid separately - (200 EGP for adults and half less children's ticket). You will also have to pay extra for photography inside.
Be sure to check the weather forecast. If there is strong wind in the future, it is better to postpone the trip, as everything will be covered in sand. And don’t forget to take a hat - this will protect you from the heat and from pestering sellers.

The number of internal visits is limited (300 people per day), so the chances of getting inside the pyramidal complex on your own, not as part of an excursion group, are not very high. But you can take great photos in front of the most famous Egyptian monument in any case, and they will remind you of this exciting journey for a long time.
