Pyramid of Djoser

Djoser was the first or second king of the 3rd Dynasty (–2650 BC) of the Old Kingdom of Egypt (). He is believed to have ruled for 19 years or, if the 19 years were biennial taxation years, 38 years. Djoser is best known for his innovative tomb, which dominates the Saqqara landscape. In this tomb he is referred to by his Horus name Netjerikhet; Djoser is a name given by New Kingdom visitors more than a thousand years later. Djoser's step pyramid is astounding in its departure from previous architecture. It sets several important precedents, perhaps the most important of which is its status as the first monumental structure made of stone. The social implications of such a large and carefully sculpted stone structure are staggering. The process of building such a structure would be far more labor-intensive than previous monuments of mud-brick. This suggests that the state, and therefore the royal government, had a new level of control of resources, both material and human. Also, from this point on, kings of the Old Kingdom are buried in the north, rather than at Abydos. Although the plan of Djoser's pyramid complex is different from later complexes, many elements persist and the step pyramid sets the stage for later pyramids of the 4th, 5th, and 6th Dynasties, including the great pyramids of Giza. Though the Dynastic Egyptians themselves did not credit him as such, most Egyptologists credit Djoser's vizier Imhotep with the design and construction of the complex. and a comment made by the 3rd century BC historian Manetho claiming Imhotep was the "inventor of building in stone". Imhotep would later be deified and known as Asclepios by the Greeks. == Precedents ==

Djoser's Pyramid draws ideas from several precedents. The most relevant precedent is found at Saqqara mastaba S3038 ( 2900 BC). The substructure lay in a deep rectangular pit, and had mudbrick walls rising to . Three sides were extended and built out to create eight shallow steps rising at an angle of 49°. This would have been an elongated step pyramid if the remaining side had not been left uncovered. In another parallel to Djoser's complex, to complete this mastaba complex a niched enclosure wall was erected. == Layout ==

Djoser's mortuary complex comprises the great trench, enclosure wall, colonnaded entrance, "T" temple, Sed festival complex, north and south pavilions, south tomb and court, western mounds, mortuary temple, and the crowning feature of it all, the step pyramid with its substructure. The complex was a landmark achievement for Egyptian architecture. It was the advent of the pyramidal form of the royal tomb and the first instance of the mass use of limestone in construction, replacing mudbrick which had been the staple building material prior. This shift to limestone – a hard, dense material compared to mudbrick – presented novel challenges to the architects, though they kept to earlier tradition, copying architectural elements and carving them into the stone. For example, the Egyptians hand-carved 1,680 -tall niches out of the limestone enclosure wall. In earlier projects, this element was built with wooden planks, ropes, and poles hung with reed mats. In a modern context, the same element would be built by laying out the blocks to form the recesses.

The crowning feature of the complex is the Step Pyramid which rises from the Saqqara plateau in six steps to a height between and . This element was revised repeatedly in construction, going through a series of developmental phases that culminated in its step pyramidal form. These phases are traditionally labelled, following Jean-Philippe Lauer's excavations: M1, M2, M3, P1, P1', and P2. In the early stages (M1 to M3) the structure had the form of a mastaba before alterations (P1 to P2) were made to create its step pyramidal form. In the first stage (M1), the mastaba had a square plan in length that rose to a height of . This was built from a core of limestone blocks arranged in horizontal beds and bound with yellow or red clay. A thick casing of fine white Tura limestone was applied to the core arranged in the same horizontal manner. The outer blocks were inclined to ~82° and the top of the mastaba likely had a slightly convex shape. A second casing of fine white limestone was applied to this which increased the mastaba's base length to square (M2). The casing was thick at the base and thick at the peak and was about lower than the initial mastaba height. The outer blocks of this second coat also had a steeper incline at ~76°. The mastaba was then extended east to cover a series of eleven shafts deep that ended in passages that led west to the burial chambers of members of Djoser's family. This extension was built from locally sourced limestone rubble and cased by thick limestone coating that formed an extension of M2. The mastaba had a new, rectangular ground plan by . At this stage the mastaba still peaked at in height, too short to be seen from outside the high enclosure wall. Egyptologists are split on the motivations behind the conception of the pyramidal form that the mastaba was converted into. Lauer believed that the alteration was made to have the tomb visible from Memphis. The fact of the mastaba's square plan led Rainer Stadelmann, however, to suggest that it was never the intended final form and that it was planned to be a pyramid from the outset. The conversion (P1) encased the mastaba (M3) extending its length by on each axis giving it a base length of by . The alteration from mastaba to pyramid came with a shift in construction. The builders used larger and better quality, roughly dressed limestone blocks – but instead of horizontal beds, they built successive inclined accretion layers thick. These leaned on each other from opposite ends providing greater stability preventing a collapse. The whole was then cased in fine white limestone with a layer of packing in between. This phase of the pyramid had four steps that rose to a height of . The decision was then made to expand the pyramid north and west from four to six steps (P1') which was then finished with a final layer of limestone casing (P2) that gave the pyramid its final form. On completion the step pyramid had a base length of by that rose to a height of and occupied a volume of . Much of the rock for the pyramid was likely quarried from the construction of the great trench. It is widely accepted that ramps would have been used to raise heavy stone to construct the pyramid, and many plausible models have been suggested. For transport, apparatuses like rollers were used in which the heavy stone could be placed and then rolled. == Pyramid substructure ==

Under the step pyramid is a labyrinth of tunneled chambers and galleries that total nearly 6 km in length and connect to a central shaft 7 m square and 28 m deep. These spaces provide room for the king's burial, the burial of family members, and the storage of goods and offerings. The entrance to the 28 m shaft was built on the north side of the pyramid, a trend that would remain throughout the Old Kingdom. The sides of the underground passages are limestone inlaid with blue faience tile to replicate reed matting. These "palace façade" walls are further decorated by panels decorated in low relief that show the king participating in the Heb-sed. Together these chambers constitute the funerary apartment that mimicked the palace and would serve as the living place of the royal ka. On the east side of the pyramid, eleven shafts 32 m deep were constructed and annexed to horizontal tunnels for royal family members. These were incorporated into the pre-existing substructure as it expanded eastward. In the storerooms along here over 40,000 stone vessels were found, many of which predate Djoser. These would have served Djoser's visceral needs in the afterlife. An extensive network of underground galleries was located to the north, west and south of the central burial chamber and crude horizontal magazines were carved into these. Shafts I–V were used for the burials of royal family members; shafts VI–XI were used as symbolic tombs for the grave goods of royal ancestors from dynasties I–II. More than 40,000 vessels, bowls and vases made of various kinds of stone were found in these galleries. Royal names such as of kings Den, Semerkhet, Nynetjer and Sekhemib were incised on the pots. It is now thought that Djoser once restored the original tombs of the ancestors, and then sealed the grave goods in the galleries in an attempt to save them. Burial chamber The burial chamber was a vault constructed of four courses of well-dressed granite. It had one opening, which was sealed with a 3.5 ton block after the burial. No body was recovered as the tomb had been extensively robbed. Lauer believes that a burial chamber of alabaster existed before the one of granite. He found evidence of limestone blocks with five pointed stars in low relief that were likely on the ceiling, indicating the first occurrence of what would become a tradition. The king sought to associate himself with the eternal North Stars that never set so as to ensure his rebirth and eternity. == Pyramid complex ==

Djoser's Step Pyramid complex included several structures pivotal to its function in both life and the afterlife. A pyramid was not simply a grave in ancient Egypt. Its purpose was to facilitate a successful afterlife for the king so that he could be eternally reborn. The symbolism of the step pyramid form, which did not survive beyond the 3rd Dynasty, is unknown, but it has been suggested that it may be a monumental symbol of the crown, especially the royal mortuary cult, since seven small step pyramids (that were not tombs) were built in the provinces. The main modern excavator of the Step Pyramid was Jean-Philippe Lauer, a French architect who reconstructed key portions of the complex. The complex covers and is about 2.5 times as large as the Old Kingdom town of Hierakonpolis. At the southern end of the court was a platform approached by steps. It has been suggested that this was a platform for the double throne. This fits into the theory proposed by Barry Kemp, and generally accepted by many, that suggests the whole step pyramid complex symbolizes the royal palace enclosure and allows the king to eternally perform the rituals associated with kingship. Each of the chapels has a sanctuary accessed by a roofless passage with walls that depict false doors and latches. Some of these buildings have niches for statues. Egyptologists believe that these buildings were related to the important double coronation of the king during the Heb-sed. == See also ==
