Ancient Egypt's Pyramids: Norwegian Researcher Unlocks Construction Secrets

ScienceDaily


Scientists from around the world have tried to understand how the Egyptians erected their giant pyramids. Now, an architect and researcher at the Norwegian University of Science and Technology (NTNU) says he has the answer to this ancient, unsolved puzzle.

Researchers have been so preoccupied by the weight of the stones that they tend to overlook two major problems: How did the Egyptians know exactly where to put the enormously heavy building blocks? And how was the master architect able to communicate detailed, highly precise plans to a workforce of 10,000 illiterate men?

A 7-million-ton structure

These were among the questions that confronted Ole J. Bryn, an architect and associate professor in NTNU's Faculty of Architecture and Fine Art when he began examining Khufu's Great Pyramid in Giza. Khufu's pyramid, better known as the Pyramid of Cheops, consists of 2.3 million limestone blocks weighing roughly 7 million tons. At 146.6 meters high, it held the record as the tallest structure ever built for nearly 4000 years.

What Bryn discovered was quite simple. He believes that the Egyptians invented the modern building grid, by separating the structure's measuring system from the physical building itself, thus introducing tolerance, as it is called in today's engineering and architectural professions.

The apex point a key

Bryn has studied the plans from the thirty oldest Egyptian pyramids, and discovered a precision system that made it possible for the Egyptians to reach the pyramid's last and highest point, the apex point, with an impressive degree of accuracy. By exploring and making a plan of the pyramid it is possible to prepare modern project documentation of not just one, but all pyramids from any given period.

As long as the architect knows the main dimensions of a pyramid, he can project the building as he would have done it with a modern building, but with building methods and measurements known from the ancient Egypt, Bryn says.

In a scientific article published May 2010 in the Nordic Journal of Architectural Research, Bryn discusses aspects that can explain the construction of a multitude of the Egyptian pyramids by taking the building grid, and not the physical building itself, as the starting point for the analysis.

A new map

If the principles behind Bryn's drawings are correct, then archaeologists will have a new "map" that demonstrates that the pyramids are not a "bunch of heavy rocks with unknown structures" but, rather, incredibly precise structures.

Ole J. Bryn's findings will be presented and explained at the exhibition The Apex Point in Trondheim from September 13th to October 1st. The exhibition is an official part of the program to celebrate the centenary (1910-2010) of the Norwegian University of Science and Technology.

The development of Bryn's theories on the building grids used in Egyptian pyramids has benefited from cooperation with Dr. Michel Barsoum, Grosvenor and Distinguished Professor at the Department of Materials Science and Engineering, Drexel University, Philadelphia.

Goddess of Fortune' Found Near Shores of Sea of Galilee

A wall painting (fresco) of Tyche, the Greek goddess of fortune, was exposed during the 11th season of excavation at the Sussita site, on the east shore of the Sea of Galilee, which was conducted by researchers of the University of Haifa. Another female figure was found during this season, of a maenad, one of the companions of the wine god Dionysus.

"It is interesting to see that although the private residence in which two goddesses were found was in existence during the Byzantine period, when Christianity negated and eradicated idolatrous cults, one can still find clear evidence of earlier beliefs," said Prof. Arthur Segal and Dr. Michael Eisenberg of the Zinman Institute of Archaeology at the University of Haifa, who headed the excavation.

The city of Sussita is located within the Sussita National Park under the management of the Israel Nature and Parks Authority, which has accompanied and assisted the excavation teams this season in enabling the continuation of excavation work and the conservation of the archaeological finds.

During the course of the excavations conducted by the team from the University of Concordia under the direction of Prof. Mark Schuler, in a residence that appeared, by the quality and complexity of its construction, to belong to one of the city notables, the excavators reached an inner courtyard with a small fountain at its center. Near the fountain they found a fresco of Tyche, who was apparently deified as the city's goddess of fortune. Her head is crowned, her youthful gaze is focused, and she has abundant brown hair beneath her crown. According to the researchers, artistic analysis has indicated that the wall painting may be dated to the end of the Roman period or the beginning of the Byzantine period (3rd-4th centuries C.E.).

The goddess Tyche was not the only mythological figure to be discovered in this compound. Found on a bone plate was a wonderfully etched relief of a maenad, one of a group of female followers of Dionysus, the god of wine. According to Greek mythology, the maenads accompanied Dionysus with frenzied dances while holding a thyrsus, a device symbolizing sexuality, fertility, and the male sexual organ associated with sexual pleasure. The maenad of Sussita was also depicted as being in the midst of a frenzied dance. The researchers believe that both manifestations of the cult of Graeco-Roman female goddesses can be dated to the end of the Roman period, but there is no doubt that the residence in which they were found continued to exist even after Christianity triumphed over idolatry.

In this season the city's Roman period basilica (1st-2nd centuries CE) began to be exposed. This is a large-sized building that incorporated the city's central commercial, social and judicial areas. Besides the excellent architectural marble items that were unearthed there, the researchers also found decorations made of "stucco," molded plaster used in the imitation of marble. "We could not fail to wonder how a relatively plebeian city could employ first-class builders and artisans. The stucco decorations demonstrate that despite everything, the city rulers were certainly not sparing of the costs and expenditure of construction," the researchers noted.

Sussita was erected on a mountain top rising to the east of the Sea of Galilee during the 2nd century B.C.E. by the Seleucid rulers who then controlled the country. The city existed during the Hellenist, Roman, Byzantine and Umayyad periods, until it was destroyed by a violent earthquake in the year 749 C.E. Together with Beth Shean and other cities on the eastern bank of the Jordan River, Sussita was one of the cultural-geographical group of Decapolis cities -- a region within which Jesus conducted some of the miracles described in the New Testament.
