Double Square and the Golden Rectangle

above: Dan Palmateer wrote of this, “it just hit me that the conjunction of the circle to the golden rectangle existed.”

Here we will continue in the mode of a lesson in Geometry where what is grasped intuitively has to have reason for it to be true. It occurred to me that the square in the top hemisphere is the twin of a square in the lower hemisphere, hence this has a relationship to the double square rectangle. So one can (1) Make a Double Square and then (2) Find the center and (3) a radius can then draw the out-circle of a double square (see diagram below).

The diagonal from the centre would be the square root of 5 if the top square is seen as two double squares of unit size, that is (4) Identify the units as nested double squares. One can then see (5) a cross within the circle holding 12 squares, but when (6) the root 5 comes down to the right horizontal then the familiar formula (root(5) – 1)/2 = 0.618 so there are many transcendent (not Fibonacci) versions of the Golden mean within in the diagram as shown below.

The in-circle of the cross, radius 2, shows how one can divide that circle into twelve equal portions as with the Zodiac, matching the twelve squares. The out-circle shows Dan’s insight as eight golden rectangles which, overlap over the four “missing” squares of the 16 square grid, which is a simpler framework for generating this geometry as a Whole.

Twelve: determining Time and Space on the Earth

At bottom, 12 radial windows showing 12 elders, crowned and playing musical instruments, rejoicing, indicating the remade world (the heavenly Jerusalem). At top, circular ends of 12 radial windows showing the 12 signs of the Zodiac, indicating the incarnation of Christ as a man on earth under the stars. Sequence from left to right has last 2 signs before first, i.e. Aquarius/Water-bearer (grey), Pisces/Fish (grey), Aries/Ram, Taurus/Bull (yellow), Gemini/Twins, Cancer/Crab (red), Leo/Lion (yellow), Virgo/Virgin, Libra/Scales, Scorpio/Scorpion, Sagittarius/Archer, Capricorn/He-goat (blue background)

The Moon was the means by which a 12-fold harmony became established on the Earth. This harmonization occurred through the lengthening of the lunar month until 12 months fitted, in a special way, within the solar year. The excess of the solar year over the lunar year of 12 months became 7/19 lunar months, causing seven extra whole months over 19 years. This 19-year (235 month) Metonic period was well-known to the ancient world, and it leads to the remarkably short cycle for the pattern of similar eclipses, we call the Saros period, which repeat every 18 years (235 minus 12 months = 223 months). And eclipses are highly visible because the disk of the Moon has come to be the same angular size as the disk of the Sun, causing total solar eclipses.
