The Human Element
One analysis of the Vitruvian Man drawn by Leonardo DaVinci shows that the paradigm of the human figure is 72 inches, or 6 feet tall, and having a 18 inch cubit, the distance from the tip of the fingers to the elbow. These numbers point to the sexagesimal system of number based upon the number six.
The Egyptians constructed the Great Pyramid of Giza to be an accurate and scale model of the Earth in the proportion of 1/43,200. The relationship of the size of the Vitruvian Man to the size of the Great Pyramid of Giza is 1/7200 -which is a fractal of 72 inches.
The full cycle of the Precession of the vernal equinoxes is completed in 25,920 years which is one degree of 360 degrees every 72 years (25,920 / 360 = 72). Again, the number 72 appears.
We are the seed and issue of the universe. And as a part of the cosmos we would certainly reflect numbers and proportions of the universe, Milky Way galaxy, the solar system, and the Earth upon which we live. Human heart-beat and respiration of lungs is synchronized with the cycles of the cosmos. Our growth rate, mental maturity, metabolism, menstruation cycle, gestation and birth follow the cycles of our planet. We could not live and successfully survive, and adjust our health and survival protocols if we were not intimately and completely interwoven with the structure and cycles of the universe.
Below are some examples of synchronism of geometry and the human form:
