The first great period of Egyptian civilization, called the Old Kingdom, began during the rule of King Zoser. The advances of the period were due mainly to Imhotep, the king's first minister. He was a skilled architect, statesman, and scholar. He was probably the architect of the famous Step Pyramid at Saqqara. The Step Pyramid was the first stone building in history and the first of the many pyramids to appear during the next 1,000 years.
The Step Pyramid was designed as a tomb for Zoser and members of his family. It was an unusual pyramid because of its broad terraces, or "steps." It consisted of seven rectangles, each rectangle smaller than the one beneath it. Within the rock was a well where the king was buried. He was surrounded by a maze of corridors and chambers that contained endless materials for his afterlife. More than 30,000 stone vessels—jugs, bowls, and vases--were buried in the chambers. This pyramid, about 200 feet (60 meters) tall, was the most important of a great number of buildings enclosed within a high wall. An entrance gate, a great court for the celebration of religious festivals, and a second tomb were built nearby. All these buildings were constructed from small blocks of limestone, a soft rock common to the region.
The form of the pyramid that we are familiar with developed quickly. The most important and famous pyramids are the three great pyramids at Giza, on the west bank of the Nile River. They were built between about 2660 and 2560 for the kings Cheops, Chephren, and Mycerinus. The pyramids were meant to house the pharaohs' bodies and serve as reminders of their almighty power.
Building the great pyramid of Cheops (2551-28) was a tremendous feat. The pyramid is so large that it could contain comfortably the entire Capitol building of Washington, D.C. The pyramid is made of about 2,300,000 blocks of finely cut limestone. These stones have an average weight of 2 1/2 tons. The largest stones were cut and floated almost 700 miles (1,125 kilometers) down the Nile to the pyramid site. With only the simplest of tools, the stones were dragged up earth ramps and set in place.
The pyramid, the tomb of the king, was only one part of a group of structures that formed the pyramid complex. Adjoining the pyramid on its eastern, or Nile, side was the pyramid temple, where the king was worshiped. From this temple a covered causeway led to the valley temple, which had access to the Nile. Clustered around the royal tombs or dug into the surrounding cliffs were smaller, flat-roofed tombs called mastabas that held the bodies of nobles. Though sometimes built of mud brick, the mastabas were more often of limestone. The sides of the buildings sloped inward. Within the long building only a small area was made into chapels for offerings and chambers to hold statues of the dead. Far below the surface a burial chamber was hollowed in the rock. After burial the shaft was filled with large stone blocks.
Parts of temples have been found, but only the temple dedicated to the sun at Abu-Gurab (near Giza) remains. It, too, was approached by a long passageway and surrounded by a high wall. Unlike all other Egyptian temples, much of this temple was open to the sun. The most important part of the building was its great center court containing an altar and an obelisk, sacred symbol of the sun. An obelisk is a four-sided pillar tapering to a miniature pyramid at the top. Usually an Egyptian obelisk was cut from one piece of stone, often covered with writings of the kings' triumphs.
