The tetractys analogy table

The four start figures alongside the fournesses of physics, philosophy, Hermeticism, Kabbalah, Freemasonry and religion. A comparison, partly explicitly speculative.

A number of other fournesses can be set against the four start figures of the tetractys. The assignments in number theory and geometry follow directly from the mathematics. The rest are interpretations, some explicitly speculative.

Polygon3the number itself, no divisor
Compound polygon6 : 2 = 3n is divisible by k
Star polygon5 : 2 = 2.5n and k are coprime
Compound star10 : 4 = 2.5n is not divisible by k, but they share a factor > 1

The four start figures, in the order of the table.

Number and form

1 2 3 4
Tetractys 1 1 + 2 = 3 1 + 2 + 3 = 6 1 + 2 + 3 + 4 = 10
Divisibility all natural numbers, the number itself coprime divisible not divisible, common factor > 1
Example point, line, triangle 5 : 2, a pentagram 6 : 2, two triangles 10 : 4, two pentagrams
Figure polygon star polygon compound polygon compound star
Angle sum of the start figure ½ full circle ½ full circle 1 full circle 1 full circle

The line stars that pass through the centre for even numbers have an angle sum of zero.

Traditions

1 2 3 4
Four elements fire (active) air (active) water (passive) earth (passive)
The four worlds of the Kabbalah Atziluth, pure spirit Beriah, spiritual form Yetzirah, formation Assiah, material realisation
Sephirot Kether (1), Crown Geburah (5), Strength Tiphareth (6), Beauty Malkuth (10), Kingdom
The three lesser lights of Freemasonry wisdom strength beauty the building of Solomon’s temple
Religion idea of God human spirit human soul human body
Kabbalah idea of God Adam Kadmon creation the fall

Note the sephirot: Kether bears the number 1, Geburah 5, Tiphareth 6 and Malkuth 10, exactly the numbers of the start figures 5 : 2, 6 : 2 and 10 : 4 and of the one from which everything proceeds.
