Abstract
According to the theory described below, the Great Pyramid of Giza, also
known as the Pyramid of Khufu or the Pyramid of Cheops was designed
starting from one shadow creation projected by a vertical rod placed at
the center of Pyramid base and of the length as the Pyramid height.
The sunlight projected on the rod generates the shadow taken into
consideration at a given time of the day, in particular noon on February
29;
