How the ancients measured the earth has been a mystery to mainstream scientists until now. I have deduced how the ancients utilized precession time, not solar time, to measure the dimensions of the earth, thus validating the anomalously accurate Maps of the Ancient Sea Kings, such as the Piris Reis, Oronteus Finaeus, Ibn Zara, Waldseemuller, and Zeno (google them), which show shorelines of supposedly then unknown continents (South America and Antarctica for instance) with stunning accuracy, which only accurate timekeeping can produce, by equating a rate, the rate of precession (72 years/degree) with distance, the distance along the sphere of the earth which the stars of the constellations appear to move because of the earth’s slow wobble, like a gyroscope in space, as it rotates around the sun, wobbling at a rate of 72 years per degree, which would wobble once after 25,920 at that rate. This anciently measured rate allowed them to project earth distances by the anticipated distances which the stars appear to move along the horizon after given lengths of time, because rate, the rate of precession in this case, is time/distance, 72 years per degree.
And with this knowledge, the ancients built the Great Pyramid of Giza, surveying its dimensions to be a reduced embodiment of an earth’s hemisphere’s dimensions by a factor of 43,200; geometry, earth measure, in practical ancient application, thus giving the ancient meaning to the word geometry, earth measure, the methodology of which was embodied in the dimensions of the Great Pyramid of Giza. (See article #2 under Ice Age Civilization for the full explanation, solving the riddle of the length of the ancient royal cubit.)
The ancient surveyors and navigators used relatively simple mechanical instruments, such as the Celtic Cross, Maui’s Tanawa, the Antikythera Mechanism, and the Mayan Staff of Power, to measure the “round face of the earth and the arch of the sky,” as described in the ancient Mexican book the Popol Vu, so the evidence is complete that the Bronze Age navigators were masters of geometry, earth measure, which can only be achieved through measurement of time, precession time by the ancients, simple astronomy, which then was co-opted to the religion of astrology, with its houses of the zodiac appearing to move along, relative to the horizon, through the years because of the slow wobble of the earth’s axis, 72 years per degree of 360 degrees.
