Some of the limestone casing was brought from Tura, across the Nile, and a few of the rooms were cased with granite from Aswan. Marks of the quarry workers are found on several of the stone blocks giving names of the work gangs such as "craftman-gang". Part-time crews of laborers probably supplemented the year-round masons and other skilled workers.
The Greek historian Heroditus reported in the fifth century BCE that his Egyptian guides told him , men were employed for three months a year for twenty years to build the Great Pyramid; modern estimates of the number of laborers tend to be much smaller.
Pyramid building was at its height from the Fourth through the Sixth Dynasties. Smaller pyramids continued to be built for more than one thousand years. Scores of them have been discovered, but the remains of others are probably still buried under the sand.
As it became clear that the pyramids did not provide protection for the mummified bodies of the kings but were obvious targets for grave robbers, later kings were buried in hidden tombs cut into rock cliffs. Although the magnificent pyramids did not protect the bodies of the Egyptian kings who built them, the pyramids have served to keep the names and stories of those kings alive to this day.

According to Redford, ancient Egyptian quarrying methods—the processes for cutting and removing stone—are still being studied.
Scholars have found evidence that copper chisels were used for quarrying sandstone and limestone, for example, but harder stones such as granite and diorite would have required stronger materials. Dolerite, a hard, black igneous rock, was used in the quarries of Aswan to remove granite. During excavation, massive dolerite "pounders" were used to pulverize the stone around the edge of the granite block that needed to be extracted.
According to Redford, 60 to 70 men would pound out the stone. At the bottom, they rammed wooden pegs into slots they had cut, and filled the slots with water. The pegs would expand, splitting the stone, and the block was then slid down onto a waiting boat. Teams of oxen or manpower were used to drag the stones on a prepared slipway that was lubricated with oil.
Redford notes that a scene from a 19th century B. Once the stones were at the construction site, ramps were built to get them into place on the pyramid. These ramps were made of mud brick and coated with chips of plaster to harden the surface.
They were "wrap-around" style, rather than straight, Redford says, "because in laying the upper layers of a great pyramid, the gradient necessary for a straight ramp would be impossible. When answering to skepticism about how such heavy stones could have been moved without machinery, Redford says, "I usually show the skeptic a picture of 20 of my workers at an archaeological dig site pulling up a two-and-a-half ton granite block.
I know it's possible because I was on the ropes, too. Editor's Note: This story has been updated April 15, since its original publication in Materials provided by Penn State University.
Stepped pyramids are prevalent in Central America. In Mesopotamia, they were called ziggurats. Laborers used 2. A number of pyramids, including the Great Pyramid of Khufu, have survived thousands of years of exposure to the elements, a tribute to the ancient architects, engineers and workers who built them.
