When you ask people what is the meaning of the word geometry, they usually eschew the actual etymological meaning, earth measure (geo metry), instead that it has to do with the measurement of angles of the various types of polygons, yet earth measure is what it really means at its root, and that earth measure in ancient times by the precession rate of the earth’s axis, the base six number 72 years/degree, which is very convenient to measure the earth when the circle of the earth is made to circumscribe a hexagon (see article #2 at http://iceagecivilizations.com), a polygon of six sides, the basis of ancient geometry.
Along with the royal cubit of ancient Egypt and much of the rest of the ancient world (including western Asia and India), the greek olympic foot (of 12.16 modern inches) was also determined with this method, five greek stadia (of 600 olympic feet) representing exactly the base perimeter length of the Great Pyramid of Giza, that’s 3,000 olympic feet or 1,760 royal cubits, the precession mapping method clearly the metric method for all the ancient earth commensurate measures, including the ancient scandic fot which is the same length as the olympic foot.
Have you wondered why 1,760 yards compose an english mile? Now you can see that it’s a carry-over from very ancient times, through the empire of Atlantis really, the mile measure originally ten stadia, yet that distance later conflated with the number of cubits (1,760) composing the half-nautical-mile base perimeter length of the Great Pyramid, thus 1,760 yards now compose the length of the modern englush mile which is 5,280 feet. The link is revealed with the fact that the fortress of the chief mining hub of the atlantean empire, now Seville, Spain, anciently known as Tarshish, had 176 towers, the source of the later conflation of the cubit system with that of the olympic (and nordic) foot (fot).
