TETRAKTYS Painting

The Pythagorean Acoustics Based on Tetraktys. Prime numbers and the law of Tetraktys. In occult and Pythagorean geometry the Tetrad is said to combine within itself all the materials from which Kosmos is produced. The Point or One, extends to a Line—the Two; a Line to a Superficies, Three; and the Superficies, Triad or Triangle, is converted into a Solid, the Tetrad or Four, by the point being placed over it. Kabalistically Kether, or Sephira, the Point, emanates Chochmah and Binah, which two, are the synonym of Mahat, in the Hindu Purânas, and this Triad, descending into matter, produces the Tetragrammaton, Tetraktys, as also the lower Tetrad.
