Arab proverb: "Man fears time, yet time fears the pyramids"
The ancient Greeks didn't title the Great Pyramid of Giza as the first wonder of the world without just cause. It was the tallest monument ever built for 4,000 years and today the pyramid is the only wonder still remaining of the ancient seven wonders. But what has exactly left people so enthralled with this ancient work for centuries? The Great Pyramid, standing with a base of 55,000 m and each side greater that 20,000 m in area, can be seen from orbit. Scientist and historians are amazed at the accuracy at which the ancient Egyptians designed the pyramid. The pyramid is a precisely aligned structure and looks north with only 3/60th a degree of error. Among other aspects, the design of the pyramid is alleged by some to have a geometric relationship with celestial bodies such as the orbit of the earth around the sun. This is widely disputed and the question remains open whether or not these relationships were done intentionally or accidentally.
When the Great Pyramid of Giza was first built, its height scaled to a fascinating 146 M. However in spite of the pyramid's ability to defeat the tests of time, it has withered slightly due to the harsh weather of the desert, civil war, and just old age in general. Today the pyramid still stand tall but nearly 10 meters shorter then its original height, at 137 M. Despite the allure pertaining to the pyramid's structure and design, the Great Pyramid of Giza can simply be appreciated for the effort with which the ancient Egyptians built this beautiful artwork.
