When you read about the classic book Hamlet’s Mill by Giorgio de Santillana and Hertha von Dechend plus the book Maps of the Ancient Sea Kings by Charles Hapgood, it’s easy to see that the ancients did indeed measure the precession rate of the earth’s axis which enabled them to map the sphere of the earth by measuring the change of position of the stars in the celestial sphere because of the precession of the earth’s axis at the rate of 72 years/degree (see Page titled Great Pyramid for Navigation).
