The poets relate, that Coelum was the most ancient of all the gods; that his parts of generation were cut off by his son Saturn; that Saturn had a numerous offspring, but devoured all his sons as soon as they were born; that Jupiter at length escaped the common fate; and when grown up, drove his father Saturn into Tartarus; usurped the kingdom; cut off his father's genitals, with the same knife wherewith Saturn had dismembered Coelum, and throwing them into the sea, thence sprung Venus.
Before Jupiter was well established in his empire, two memorable wars were made upon him: the first by the Titans, in subduing of whom, Sol, the only one of the Titans who favoured Jupiter, performed him singular service; the second by the giants, who being destroyed and subdued by the thunder and arms of Jupiter, he now reigned secure.
This fable appears to be an enigmatical account of the origin of all things, not greatly differing from the philosophy afterwards embraced by Democritus, who expressly asserts the eternity of matter, but denies the eternity of the world; thereby approaching to the truth of sacred writ, which makes chaos, or uninformed matter, to exist before the six days' work.
The meaning of the fable seems to be this: Coelum denotes the concave space, or vaulted roof that incloses all matter, and Saturn the matter itself, which cuts off all power of generation from his father; as one and the same quantity of matter remains invariable in nature, without addition or diminution. But the agitations and struggling motions of matter, first produced certain imperfect and ill-joined compositions of things, as it were so many first rudiments, or essays of worlds; till, in process of time, there arose a fabric capable of preserving its form and structure. Whence the first age was shadowed out by the reign of Saturn; who, on account of the frequent dissolutions, and short durations of things, was said to devour his children. And the second age was denoted by the reign of Jupiter, who thrust, or drove those frequent and transitory changes into Tartarus - a place expressive of disorder. This place seems to be the middle space, between the lower heavens and the internal parts of the earth, wherein disorder, imperfection, mutation, mortality, destruction, and corruption, are principally found.
Venus was not born during the former generation of things, under the reign of Saturn; for whilst discord and jar had the upper hand of concord and uniformity in the matter of the universe, a change of the entire structure was necessary. And in this manner things were generated and destroyed, before Saturn was dismembered. But when this manner of generation ceased, there immediately followed another, brought about by Venus, or a perfect and established harmony of things; whereby changes were wrought in the parts, whilst the universal fabric remained entire and undisturbed. Saturn, however, is said to be thrust out and dethroned, not killed, and become extinct; because, agreeably to the opinion of Democritus, the world might relapse into its old confusion and disorder, which Lucretius hoped would not happen in his time.
But now, when the world was compact, and held together by its own bulk and energy, yet there was no rest from the beginning; for first, there followed considerable motions and disturbances in the celestial regions, though so regulated and moderated by the power of the Sun prevailing over the heavenly bodies, as to continue the world in its state. Afterwards there followed the like in the lower parts, by inundations, storms, winds, general earthquakes, &c., which, however, being subdued and kept under, there ensued a more peaceable and lasting harmony, and consent of things.
It may be said of this fable, that it includes philosophy; and again, that philosophy includes the fable; for we know, by faith, that all these things are but the oracle of sense, long since ceased and decayed; but the matter and fabric of the world being justly attributed to a creator.
