Double Triangle

Double Triangle
The Pythagoreans who included in their Dekad the entire Kosmos,  held the number twelve in still higher reverence as it represented the sacred Tetraktys multiplied by three, which  gave a trinity of perfect squares called tetrads. The Hermetic philosophers or Occultists following in their steps
represented this number twelve in the double triangle’’—the great universe or the macrocosm as shown in this figure—and included in it the pentagram, or the microcosm, called by them the little universe.

Dividing the twelve letters of the outer angles into four groups of triads, or three groups of tetrads, they obtained the Dodekagon, a regular geometric polygon, bounded by twelve equal sides and containing twelve equal angles, which symbolized with the ancient Chaldæans the twelve “great gods,”* and with the Hebrew Kabalists the ten Sephiroth, or creative powers of nature, emanated from Sephira (Divine Light), herself the chief Sephiroth and emanation from Hakoma, the Supreme (or Unmanifested) Wisdom, and Ain-Suph the Endless; viz., three groups of triads of the Sephiroth and a fourth triad, composed of Sephira, Ain-Suph and Hakoma, the Supreme Wisdom which ‘‘cannot he understood by reflection,’’ and which ‘‘lies concealed within and without the cranium of Long Face,’’ the uppermost head of the upper triangle forming the ‘‘Three Kabalistic Faces,” making up the twelve. Moreover, the twelve figures give two squares or the double Tetraktys, representing in the Pythagoræan symbology the two worlds—the spiritual and the physical. The eighteen inner and six central angles yield, besides twenty-four, twice the sacred macrocosmic number, also the twenty-four ‘‘divine unmanifested
