(72) All fountains and principles whirl round and always remain in a ceaseless revolution.

(19) And so every Element qualifies [or acts] in its own Source [or Manner of Operation,] and one could do nothing without the other, neither could one have any Mobility without the other. For one generates the other, and they go all four out of one Original, and it is in its Birth but one only [Thing or] Substance as I have mentioned before at large about the Creation, concerning the Birth of the four Elements.

(617) coloured by the reflected light of the seventh; the second and fifth [Saturn and Mercury] are in colour like one another, and yellower than the preceding; the third [Venus] has the whitest light; the fourth [Mars] is reddish; the sixth [Jupiter] is in whiteness second. Now the whole spindle has the same motion; but, as the whole revolves in one direction, the seven inner circles move slowly in the other, and of these the swiftest is the eighth; next in swiftness are the seventh, sixth, and fifth, which move together; third in swiftness appeared to move according to the law of this reversed motion the fourth; the third appeared fourth and the second fifth. The spindle turns on the knees of Necessity; and on the upper surface of each circle is a siren, who goes round with them, hymning a single tone or note. The eight together form one harmony; and round about, at equal intervals, there is another band, three in number, each sitting upon her throne: these are the Fates, daughters of Necessity, who are clothed in white robes and have chaplets upon their heads, Lachesis and Clotho and Atropos, who accompany with their voices the harmony of the sirens—Lachesis singing of the past, Clotho of the present, Atropos of the future; Clotho from time to time assisting with a touch of her right hand the revolution of the outer circle of the whorl or spindle, and Atropos with her left hand touching and guiding the inner ones, and Lachesis laying

Even so the eighth and ninth; and every one More slowly moved, according as it was In number distant farther from the first. And that one had its flame most crystalline From which less distant was the stainless spark, I think because more with its truth imbued. My Lady, who in my anxiety Beheld me much perplexed, said: "From that point Dependent is the heaven and nature all. Behold that circle most conjoined to it, And know thou, that its motion is so swift Through burning love whereby it is spurred on." And I to her: "If the world were arranged In the order which I see in yonder wheels, What's set before me would have satisfied me;
