Bent Pyramid

The Bent Pyramid is an ancient Egyptian pyramid located at the royal necropolis of Dahshur, approximately 40 kilometres south of Cairo, built under the Old Kingdom Pharaoh Sneferu (c. 2600 BC). A unique example of early pyramid development in Egypt, this was the second pyramid built by Sneferu.

The Bent Pyramid rises from the desert at a 54-degree inclination, but the top section (above 47 metres) is built at the shallower angle of 43 degrees, lending the pyramid a visibly 'bent' appearance.

Overview

Archaeologists now believe that the Bent Pyramid represents a transitional form between step-sided and smooth-sided pyramids. It has been suggested that due to the steepness of the original angle of inclination the structure may have begun to show signs of instability during construction, forcing the builders to adopt a shallower angle to avert the structure's collapse. This theory appears to be borne out by the fact that the adjacent Red Pyramid, built immediately afterwards by the same pharaoh, was constructed at an angle of 43 degrees from its base. This fact also contradicts the theory that at the initial angle the construction would take too long because Sneferu's death was nearing, so the builders changed the angle to complete the construction in time. In 1974, Kurt Mendelssohn suggested the change of the angle to have been made as a stability precaution in reaction to a catastrophic collapse of the Meidum Pyramid while it was still under construction.
The reason why Sneferu abandoned the Meidum Pyramid and its Step Pyramid may have been a change in ideology. The royal tomb was no longer considered as a staircase to the stars; instead, it was served as a symbol of the solar cult and of the primeval mound from which all life sprang.

It is also unique amongst the approximately ninety pyramids to be found in Egypt, in that its original polished limestone outer casing remains largely intact. British structural engineer Peter James attributes this to larger clearances between the parts of the casing than used in later pyramids; these imperfections would work as expansion joints and prevent the successive destruction of the outer casing by thermal expansion.

The ancient formal name of the Bent Pyramid is generally translated as ''(The)-Southern-Shining-Pyramid,'' or ''Sneferu-(is)-Shining-in-the-South''. In July 2019, Egypt decided to open the Bent Pyramid for tourism for the first time since 1965. Tourists are able to reach two 4600-year-old chambers through a 79-metre narrow tunnel built from the northern entrance of the pyramid. The 18-metre-high "side pyramid", which is assumed to have been built for Sneferu's wife Hetepheres will also be accessible. It is the first time this adjacent pyramid has been opened to the public since its excavation in 1956.

Interior passages

The Bent Pyramid has two entrances, one fairly low down on the north side, to which a substantial wooden stairway has been built for the convenience of tourists. The second entrance is high on the west face of the pyramid. Each entrance leads to a chamber with a high, corbelled roof; the northern entrance leads to a chamber that is below ground level, the western to a chamber built in the body of the pyramid itself. A hole in the roof of the northern chamber (accessed today by a high and rickety ladder long) leads via a rough connecting passage to the passage from the western entrance.

The western entrance passage is blocked by two stone blocks which were not lowered vertically, as in other pyramids, but slid down 45° ramps to block the passage. One of these was lowered in antiquity and a hole has been cut through it, the other remains propped up by a piece of ancient cedar wood. The connecting passage referenced above enters the passage between the two portcullises.

Causeway

A causeway leads from the Bent Pyramids' northeast toward the pyramid with the valley temple. The causeway was paved with limestone blocks and had a low limestone wall on each side. In fact, there may have been a second causeway that lead down to a dock or landing stage, but there is no excavation that can prove this assumption yet.

Pyramid temple

On the east side of the pyramid there are the fragmentary remains of the pyramid temple. Like the pyramid temple of the Meidum pyramid, there are two stelae behind the temple, though of these only stumps remain. There is no trace of inscription to be seen. The temple remains are fragmentary but it is presumed to be similar to that of the Meidum temple.

Satellite pyramid

A satellite pyramid, suggested by some Egyptologists to have been built to house the pharaoh's '' ka'', is located 55 metres south of the Bent Pyramid. The satellite pyramid originally measured 26 metres in height and 52.80 metres in length, with faces inclining 44°30'.Nearly identical to the inclination of the Red Pyramid The structure is made of limestone blocks, relatively thick, arranged in horizontal rows and covered with a layer of fine limestone from Tura. The burial chamber is accessible from a descending corridor with its entrance located 1.10 metres above the ground in the middle of the north face. The corridor, inclined at 34°, originally measured 11.60 metres in length. A short horizontal passage connects the corridor with an ascending corridor, inclined at 32° 30', leading up to the chamber.

The design of the corridors is similar to the one found in the Great Pyramid of Giza, where the Grand Gallery takes up the place of the ascending corridor. The corridor leads up to the burial chamber (called this despite that it most probably never contained any sarcophagus). The chamber, located in the center of the pyramid, has a corbel vault ceiling and contains a four metres deep shaft, probably dug by treasure hunters, in the southeast part of the chamber.

Like the main pyramid, the satellite had its own altar with two stelae located at the eastern side.

Man-made landscape

As the first geometrically "true" pyramid in the world, the Bent Pyramid shows its uniqueness not only from the method of construction but also manifests through the surrounding landscape. Nicole Alexanian and Felix Arnold, two distinguished German archeologists, provided a new insight toward the meaning and function for the Bent Pyramid in their book named ''The complex of the Bent Pyramid as a landscape design project''. They noticed that the sites of the Bent Pyramid sits aside in the middle of a pristine desert area instead of fertile area near the Nile River like all the other pyramids. After a long period detailed investigation, they believed the landscape surrounding the Bent Pyramid is in fact man-made.
When the archaeologists observed the landscape closely, the plateau of the pyramid seemed leveled artificially and nearby escarpment and trenches were all made by human beings. Moreover, there were a few traces left indicating a build-up of garden enclosure. The impact of humans on the landscape is also represented by the presence of a wadi channel connecting the Bent Pyramid to a harbor, which shows a distinct difference between the southern and northern side of the channel. It shows a substantial difference in level with regards to the finding. The slope of southern wadi channel seemed to have been rectified when the archaeologists compared it to the natural and twisted northern side. Arne Ramisch supported this idea by providing evidence that displays a low correlation of fraternal patterns of channel and natural topography in the environs, which is southern side of wadi, of the Bent Pyramid.

The purpose of this man-made construction might hold mythical meaning and ritual function. Based on available evidence, garden enclosure and water basins both are the counterparts of funeral rites which indicates a regular practice of rituals at Dahshur. However, there is also another implication states that the garden closure helping to create satisfactory living environment in the desert.Alexanian, Nicole; Arnold, Felix (2016). Martina Ullmann (ed.). ''The Complex of the Bent Pyramid as a Landscape Design Project''. 10. Ägyptologische Tempeltagung: Ägyptische Tempel zwischen Normierung und Individualität: 29-31 August 2014. Munich, Germany: Harrassowitz Verlag. pp. 1–16. Retrieved 19 November 2020. Other than that, the leveled plateau, the quarrying trenches on the western and southern sides of the pyramid, and the nearby smaller tombs cooperate together to emphasize the monumentality of the Bent Pyramid, aiding by its long distance from the surrounding structures. These features represent the imprinting social hierarchy in the creation of this landscape, which furthermore represents the power of Egyptian King at that time. Alexanian and Arnold describes this construction in a concise phrase: an artificial mountain erected within an artificial landscape.
