The PYRAMIDS AND THE GREAT SPHINX rise inexplicably from the desert at Giza, relics of a vanished culture. They dwarf the approaching sprawl of modern Cairo, a city of 16 million. The largest pyramid, built for the Pharaoh Khufu around 2530 B.C. and intended to last an eternity, was until early in the twentieth century the biggest building on the planet. To raise it, laborers moved into position six and a half million tons of stone—some in blocks as large as nine tons—with nothing but wood and rope. During the last 4,500 years, the pyramids have drawn every kind of admiration and interest, ranging in ancient times from religious worship to grave robbery, and, in the modern era, from New-Age claims for healing "pyramid power" to pseudoscientific searches by "fantastic archaeologists" seeking hidden chambers or signs of alien visitations to Earth. As feats of engineering or testaments to the decades-long labor of tens of thousands, they have awed even the most sober observers.
