Hippolytus

“ And Diodorus the Eretrian, [12] and Aristoxenus [13] the musician, assert that Pythagoras came to Zaratas [14] the Chaldean, and that he explained to him that there are two original causes of things, father and mother, and that father is light, but mother darkness; and that of the light the parts are hot, dry, not heavy, light, swift; but of darkness, cold, moist, weighty, slow; and that out of all these, from female and male, the world consists. But the world, he says, is a musical harmony; [15] wherefore, also, that the sun performs a circuit in accordance with harmony. ”

“ For when the square itself is multiplied [10] into itself, a biquadratic is the result. But when the square is multiplied into the cube, the result is the product of a square and cube; and when the cube is multiplied into the cube, the product of two cubes is the result. So that all the numbers from which the production of existing (numbers) arises, are seven,—namely, number, monad, square, cube, biquadratic, quadratic-cube, cubo-cube.
This philosopher likewise said that the soul is immortal, and that it subsists in successive bodies. ”

“ Cicero says of Aristoxenus, “that he was so charmed with his own harmonies, that he sought to transfer them into investigations concerning our corporeal and spiritual nature.”↑ Zaratas is another form of the name Zoroaster.↑ Or, “is a nature according to musical harmony” (preceding note) ; or, “The cosmical system is nature and a musical harmony.”↑ Zaratas, or Zoroaster, is employed as a sort of generic denomination for philosopher by the Orientals, who, whatever portions of Asia they inhabit, mostly ascribe their speculative systems to a Zoroaster. ”
