The Orientation of the Pyramids and the Chronology of the Old Kingdom in Egypt (original) (raw)

Development of the astronomical science in estimating motion of stars has been of much help in solving the problem of the ancient chronology. Solving the problem of the orientation of the Egyptian pyramids due to north-south determines the time of the Fourth Dynasty rule. The vertical alignment of two stars, Megrez and Phecda on the same side of the celestial Pole could have been used to determine north-south direction with considerable precision. According to the orientation of the Khufu’s pyramid, one can calculate the time of his reign from 2580 to 2548 BC.
