The above diagram contains information with can generally only be grasped by using a geometrical diagram. Its focus is the properties of a right triangle that is 4 times larger than its third and shortest side. The left hand view illustrates what we call Pythagoras’ theorum, namely that

“The squares of the shorter sides add up to the square of the longest side.”

Here this is shown as 144 + 9 = 153 because, if the third side is three lunar months long, then the 4-long base is 12 lunar months, hence the square of 12 is 144″. The longest side is then 153, the diagonal of the four squares rectangle, and the square root of 153 is 12.369 lunar months, the solar year when measured in lunar months.

Before Pythagoras, the Egyptians had a long tradition of geometrical mathematics which fed into their art in which designs can be seen to obey a grid of squares. Their view of Pythagoras’ theorum can therefore be put within a greater world of geometrical transforms using grids.

In the above, one can see this view (called *Canevas *by Schwaller de Lubicz, *The Temple of Man*) in which the larger square is seen to fit when angled into a 5-by-5 grid (see right). The extra width and height of the grid enables the smallest square to be seen in this common framework of 25 squares.

The largest square of area 153 is distinguished as an integer, rather than its square root. Thus this is not a Pythagorean triangle with all sides integral, but rather the two smaller sides being integer allows them to be placed within a grid. Somewhat rare though is the arising of an integer on the square, so that Jesus disciples in the gospel of John could comment, in being asked to throw their net on the right side, they then caught 153 fish!

If the diagram was in its least numbers, the 153 would be 9 times smaller as 17 and so the 12.369 would be √9 × √17 instead. And in sacred number science, the interaction of numbers can be seen to be determined by the prime numbers which then make larger numbers such as 153 = 9 × 17. This 17 is known to be a factor of the node cycle of 18.618 solar years, which is 6800 days long and 6800 = 400 × 17.

When two lengths of astronomical time share a larger prime such as 17, it indicates numerical compatibility between two periods, and so the solar year of √153 lunar months (in which the sun moves once around the Ecliptic) has some affinity with the 6800-day period during which its orbital nodes also move once through the Zodiac.

If the larger, yellow square has 6800 days within it, the square root is 20 × √17, whilst the square of the solar year had 153, the square root being 3 × √17.

The new imagined diagram would be 20/3 relative to the above one. Without explaining how this could be, the point is that this cannot be known by the human mind without using sacred geometry which can notate how a higher intelligence might have organised the time environment of Earth according to definite criteria. Further examples can be found in my Book, *Sacred Geometry: Language of the Angels*. The book is not about sacred geometry as a compendium of traditional knowledge but rather shows how it was that sacred geometry came into the human mind (and architecture) through the initial study of time periods as counted lengths, revealing angelic coincidences.

There is much else to know about the lunation triangle linking the lunar and solar years, discovered about 3 decades ago by my brother Robin Heath.
