Abstract
The paper is an attempt to show the architectonic method of the ancient Egyptian designers for encoding the horizontal-projections, of the moon's declinations during two events of the minor lunar standstills, in the design of the site-plan of the horizon of the Giza pyramids, using the methods of descriptive geometry. It shows that the distance of the eastern side of the second Giza pyramid from the north-south axis of the great pyramid encodes a projection of a lunar declination, when earth's obliquity-angle was similar to 24.10 degrees. Besides, it shows that the angle of inclination of the causeway: of the second Giza pyramid, of similar to 13.54 degrees south of the cardinal east, encodes the projection of another lunar declination when earth's obliquity-angle reaches similar to 22.986 degrees. In addition, it shows the encoded coordinate system in the site-plan of the horizon of the Giza pyramids.
