During Egypt's Old Kingdom (time line), the pharaohs established a stable central government in the fertile Nile Valley. Perhaps the greatest testaments to their power were the pyramids and other tombs built to shelter them in the afterlife.
Kings of the Dead
Ancient Egyptians believed that when the pharaoh died, he became Osiris, king of the dead. The new pharaoh became Horus, god of the heavens and protector of the sun god. This cycle was symbolized by the rising and setting of the sun.
Some part of a dead pharaoh's spirit, called his ka, was believed to remain with his body. And it was thought that if the corpse did not have proper care, the former pharaoh would not be able to carry out his new duties as king of the dead. If this happened, the cycle would be broken and disaster would befall Egypt.
To prevent such a catastrophe, each dead pharaoh was mummified, which preserved his body. Everything the king would need in his afterlife was provided in his grave—vessels made of clay, stone, and gold, furniture, food, even doll-like representations of servants, known as ushabti. His body would continue to receive food offerings long after his death.
Tombs Fit for Kings
To shelter and safeguard the part of a pharaoh's soul that remained with his corpse, Egyptians built massive tombs—but not always pyramids.
Before the pyramids, tombs were carved into bedrock and topped by flat-roofed structures called mastabas. Mounds of dirt, in turn, sometimes topped the structures.
The pyramid shape of later tombs could have come from these mounds. More likely, Egyptian pyramids were modeled on a sacred, pointed stone called the benben. The benben symbolized the rays of the sun; ancient texts claimed that pharaohs reached the heavens via sunbeams.
Who Built the Pyramids?
Contrary to some popular depictions, the pyramid builders were not slaves or foreigners. Excavated skeletons show that they were Egyptians who lived in villages developed and overseen by the pharaoh's supervisors.
The builders' villages boasted bakers, butchers, brewers, granaries, houses, cemeteries, and probably even some sorts of health-care facilities—there is evidence of laborers surviving crushed or amputated limbs. Bakeries excavated near the Great Pyramids could have produced thousands of loaves of bread every week.
Some of the builders were permanent employees of the pharaoh. Others were conscripted for a limited time from local villages. Some may have been women: Although no depictions of women builders have been found, some female skeletons show wear that suggests they labored with heavy stone for long periods of time.
Graffiti indicates that at least some of these workers took pride in their work, calling their teams "Friends of Khufu," "Drunkards of Menkaure," and so on—names indicating allegiances to pharaohs.
An estimated 20,000 to 30,000 workers built the Pyramids at Giza over 80 years. Much of the work probably happened while the River Nile was flooded.
Huge limestone blocks could be floated from quarries right to the base of the Pyramids. The stones would likely then be polished by hand and pushed up ramps to their intended positions.
It took more than manual labor, though. Architects achieved an accurate pyramid shape by running ropes from the outer corners up to the planned summit, to make sure the stones were positioned correctly. And priests-astronomers helped choose the pyramids' sites and orientations, so that they would be on the appropriate axis in relation to sacred constellations.
From stone pusher to priest, every worker would likely have recognized his or her role in continuing the life-and-death cycle of the pharaohs, and thereby in perpetuating the glory of Egypt.
Pyramid symbolism
The shape of Egyptian pyramids is thought to represent the primordial mound from which the Egyptians believed the earth was created. The shape of a pyramid is thought to be representative of the descending rays of the sun, and most pyramids were faced with polished, highly reflective white limestone, in order to give them a brilliant appearance when viewed from a distance. Pyramids were often also named in ways that referred to solar luminescence. For example, the formal name of the Bent Pyramid at Dahshur
The Southern Shining Pyramid, and that of Senwosret at el-Lahun was
Senwosret is Shining.
While it is generally agreed that pyramids were burial monuments, there is continued disagreement on the particular theological principles that might have given rise to them. One theory is that they were designed as a type of "resurrection machine."
The Egyptians believed the dark area of the night sky around which the stars appear to revolve was the physical gateway into the heavens. One of the narrow shafts that extends from the main burial chamber through the entire body of the Great Pyramid points directly towards the center of this part of the sky. This suggests the pyramid may have been designed to serve as a means to magically launch the deceased pharaoh's soul directly into the abode of the gods.
All Egyptian pyramids were built on the west bank of the Nile, which as the site of the setting sun was associated with the realm of the dead in Egyptian mythology.
Number and location of pyramids
In 1842 Karl Richard Lepsius produced the first modern list of pyramids, in which he counted 67. A great many more have since been discovered. As of November 2008, 118 Egyptian pyramids have been identified.
The location of Pyramid 29, which Lepsius called the "Headless Pyramid", was lost for a second time when the structure was buried by desert sands subsequent to Lepsius' survey. It was only found again during an archaeological dig conducted in 2008.
Many pyramids are in a poor state of preservation or buried by desert sands. If visible at all they may appear as little more than mounds of rubble. As a consequence archaeologists are continuing to identify and study previously unknown pyramid structures.
The most recent pyramid to be discovered is that of Queen Sesheshet, mother of 6th Dynasty Pharaoh Teti, located at Saqqara. The discovery was announced by Zahi Hawass, Secretary General of the Egyptian Supreme Council of Antiquities, on 11 November 2008.
All of Egypt's pyramids, except the small Third Dynasty pyramid of Zawyet el-Amwat (or Zawyet el-Mayitin), are sited on the west bank of the Nile, and most are grouped together in a number of pyramid fields. The most important of these are listed geographically, from north to south, below.
Abu Rawash
Abu Rawash is the site of Egypt's most northerly pyramid (other than the ruins of Lepsius pyramid number one)
— the mostly ruined Pyramid of Djedefre, son and successor of Khufu. Originally it was thought that this pyramid had never been completed, but the current archaeological consensus is that not only was it completed, but that it was originally about the same size as the Pyramid of Menkaure, which would have placed it among the half-dozen or so largest pyramids in Egypt.
Its location adjacent to a major crossroads made it an easy source of stone. Quarrying — which began in Roman times — has left little apart from about 15 courses of stone superimposed upon the natural hillock that formed part of the pyramid's core. A small adjacent satellite pyramid is in a better state of preservation.
Giza
Giza is the location of the Pyramid of Khufu (also known as the "Great Pyramid" and the "Pyramid of Cheops"); the somewhat smaller Pyramid of Khafre (or Kephren); the relatively modest-sized Pyramid of Menkaure (or Mykerinus), along with a number of smaller satellite edifices known as "Queen's pyramids"; and the Great Sphinx.
Of the three, only Khafre's pyramid retains part of its original polished limestone casing, near its apex. This pyramid appears larger than the adjacent Khufu pyramid by virtue of its more elevated location, and the steeper angle of inclination of its construction — it is, in fact, smaller in both height and volume.
The Giza Necropolis has been a popular tourist destination since antiquity, and was popularized in Hellenistic times when the Great Pyramid was listed by Antipater of Sidon as one of the Seven Wonders of the World. Today it is the only one of those wonders still in existence.
Zawyet el-Aryan
This site, halfway between Giza and Abu Sir, is the location for two unfinished Old Kingdom pyramids. The northern structure's owner is believed to be the Pharaoh Nebka, while the southern structure is attributed to the Third Dynasty Pharaoh Khaba, also known as Hudjefa, successor to Sekhemkhet. Khaba's four-year tenure as pharaoh more than likely explains the similar premature truncation of his step pyramid. Today it is approximately twenty meters high; had it been completed it is likely to have exceeded 40.
Abu Sir
There are a total of fourteen pyramids at this site, which served as the main royal necropolis during the Fifth Dynasty. The quality of construction of the Abu Sir pyramids is inferior to those of the Fourth Dynasty — perhaps signaling a decrease in royal power or a less vibrant economy. They are smaller than their predecessors, and are built of low-quality local limestone.
The three major pyramids are those of Niuserre (which is also the most intact), Neferirkare Kakai and Sahure. The site is also home to the incomplete Pyramid of Neferefre. All of the major pyramids at Abu Sir were built as step pyramids, although the largest of them — the Pyramid of Neferirkare Kakai — is believed to have originally been built as a step pyramid some 70 metres high and then later transformed into a "true" pyramid by having its steps filled in with loose masonry.
Saqqara
Major pyramids located here include the Step Pyramid of Djoser — generally identified as the world's oldest substantial monumental structure to be built of finished stone — the Pyramid of Merykare, the Pyramid of Userkaf and the Pyramid of Teti. Also at Saqqara is the Pyramid of Unas, which retains a pyramid causeway that is one of the best-preserved in Egypt. This pyramid was also the subject of one of the earliest known restoration attempts, conducted by a son of Ramesses II. Saqqara is also the location of the incomplete step pyramid of Djoser's successor Sekhemkhet, known as the Buried Pyramid. Archaeologists believe that had this pyramid been completed it would have been larger than Djoser's.
South of the main pyramid field at Saqqara is a second collection of later, smaller pyramids, including those of Pepi I, Isesi, Merenre, Ibi and Pepi II. Most of these are in a poor state of preservation.
The Fourth Dynasty pharaoh Shepseskaf either did not share an interest in, or have the capacity to undertake pyramid construction like his predecessors. His tomb, which is also sited at south Saqqara was instead built as an unusually large mastaba and offering temple complex. It is commonly known as the Mastaba of Faraoun.
A previously unknown pyramid was discovered at north Saqqara in late 2008. It is believed to be the tomb of Teti's mother, it currently stands approx 5m high, although the original height was closer to 14m. The opening of the tomb is scheduled for early December 2008.
Dahshur
This area is arguably the most important pyramid field in Egypt outside Giza and Saqqara, although until 1996 the site was inaccessible due to its location within a military base, and was relatively unknown outside archaeological circles.
The southern Pyramid of Snofru, commonly known as the Bent Pyramid, is believed to be the first Egyptian pyramid intended by its builders to be a "true" smooth-sided pyramid from the outset; the earlier pyramid at Meidum had smooth sides in its finished state - but it was conceived and built as a step pyramid, before having its steps filled in and concealed beneath a smooth outer casing.
As a true smooth-sided structure, the Bent Pyramid was only a partial success — albeit a unique, visually imposing one; it is also the only major Egyptian pyramid to retain a significant proportion of its original smooth outer limestone casing intact. As such it serves as the best contemporary example of how the ancient Egyptians intended their pyramids to look.
Several kilometeres to the north of the Bent Pyramid is the last — and most successful — of the three pyramids constructed during the reign of Snofru; the Red Pyramid is the world's first successfully completed smooth-sided pyramid. The structure is also the third largest pyramid in Egypt — after the pyramids of Khufu and Khafre at Giza.
Also at Dahshur is the pyramid known as the Black Pyramid of Amenemhet III, as well as a number of small, mostly ruined subsidiary pyramids.
Mazghuna
Located to the south of Dahshur, this area was used in the First Intermediate Period by several kings who constructed their pyramids out of mudbrick.
Lisht
Two major pyramids are known to have been built at Lisht — those of Amenemhat I and his son, Senusret I. The latter is surrounded by the ruins of ten smaller subsidiary pyramids. One of these subsidiary pyramids is known to be that of Amenemhat's cousin, Khaba II.
The site which is in the vicinity of the oasis of Fayyum, midway between Dahshur and Meidum, and about 100 kilometres south of Cairo, is believed to be in the vicinity of the ancient city of Itjtawy (the precise location of which remains unknown), which served as the capital of Egypt during the 12th Dynasty.
Meidum
The pyramid at Meidum is one of three constructed during the reign of Sneferu, and is believed by some to have been started by that pharaoh's father and predecessor, Huni. However, that attribution is uncertain, as no record of Huni's name has been found at the site.
It was constructed as a step pyramid, and then later converted into the first "true" smooth-sided pyramid when the steps were filled in, and an outer casing added.
The pyramid suffered several catastrophic collapses in ancient and medieval times; medieval Arab writers described it as having 7 steps - although today only the three uppermost of these remain, giving the structure its odd, tower-like appearance. The hill on which the pyramid is situated is not a natural landscape feature — it is the small mountain of debris created when the lower courses and outer casing of the pyramid gave way.
Hawara
Amenemhet III was the last powerful ruler of the 12th Dynasty, and the pyramid he built at Hawarra, near Faiyum, is believed to post-date the so-called "Black Pyramid" built by the same ruler at Dahshur. It is the Hawarra pyramid that is believed to have been Amenemhet's final resting place.
el-Lahun
The pyramid of Senusret II at el-Lahun is the southernmost royal-tomb pyramid structure in Egypt. Its builders reduced the amount of work necessary to construct it by ingeniously using as its foundation and core a 12-meter-high natural limestone hill.
