“The Pythagoreans say that the triangle is the absolute principle of generation of begotten things, and of their form; that is why Timaeus says that the reasons of physical being, and of the regular formation of the elements are triangular; indeed, they have the three dimensions, in unity they gather the elements which in themselves are absolutely divided and changing; they are filled with the infinity characteristic of matter, and above the material beings they form bonds that indeed are frail. That is why triangles are bounded by straight lines, and have angles which unite the lines, and are their bonds. Philolaus was therefore right in devoting the angle of the triangle to four divinities, Kronos, Hades, Ares, and Bacchus, under these four names combining the fourfold disposition of the elements, which refers to the superior part of the universe, starting from the sky, or sections of the zodiac. Indeed, Kronos presides over everything humid and cold in essence; Ares, over everything fiery; Hades contains everything terrestrial, and Dionysus directs the generation of wet and warm things, represented by wine, which is liquid and warm. These four divinities divide their secondary operations, but they remain united; that is why Philolaus, by attributing to them one angle only, wished to express this power of unification.”
