De Rerum Natura

The light of the sun, the many-rayed, begins

To redden into gold, over the grass

Begemmed with dew. When all of these are brought

Together overhead, the clouds on high

With now concreted body weave a cover

Beneath the heavens. And thuswise ether too,

Light and diffusive, with concreted body

On all sides spread, on all sides bent itself

Into a dome, and, far and wide diffused

On unto every region on all sides,

Thus hedged all else within its greedy clasp.

Hard upon ether came the origins

Of sun and moon, whose globes revolve in air

Midway between the earth and mightiest ether,-

For neither took them, since they weighed too little

To sink and settle, but too much to glide

Along the upmost shores; and yet they are

In such a wise midway between the twain

As ever to whirl their living bodies round,

And ever to dure as parts of the wide Whole;

In the same fashion as certain members may

In us remain at rest, whilst others move.

When, then, these substances had been withdrawn,

Amain the earth, where now extend the vast

Cerulean zones of all the level seas,

Caved in, and down along the hollows poured

The whirlpools of her brine; and day by day

The more the tides of ether and rays of sun

On every side constrained into one mass

The earth by lashing it again, again,

Upon its outer edges (so that then,

Being thus beat upon, 'twas all condensed

About its proper centre), ever the more

The salty sweat, from out its body squeezed,

Augmented ocean and the fields of foam

By seeping through its frame, and all the more

Those many particles of heat and air

Escaping, began to fly aloft, and form,

By condensation there afar from earth,

The high refulgent circuits of the heavens.

The plains began to sink, and windy slopes

Of the high mountains to increase; for rocks

Could not subside, nor all the parts of ground

Settle alike to one same level there.

Thus, then, the massy weight of earth stood firm

With now concreted body, when (as 'twere)

All of the slime of the world, heavy and gross,

Had run together and settled at the bottom,

Like lees or bilge. Then ocean, then the air,

Then ether herself, the fraught-with-fire, were all

Left with their liquid bodies pure and free,

And each more lighter than the next below;

And ether, most light and liquid of the three,

Floats on above the long aerial winds,

Nor with the brawling of the winds of air

Mingles its liquid body. It doth leave

All there- those under-realms below her heights-

There to be overset in whirlwinds wild,-

Doth leave all there to brawl in wayward gusts,

Whilst, gliding with a fixed impulse still,

Itself it bears its fires along. For, lo,

That ether can flow thus steadily on, on,

With one unaltered urge, the Pontus proves-

That sea which floweth forth with fixed tides,

Keeping one onward tenor as it glides.

Now let us sing what makes the stars to move.

In first place, if the mighty sphere of heaven

Revolveth round, then needs we must aver

That on the upper and the under pole

Presses a certain air, and from without

Confines them and encloseth at each end;

And that, moreover, another air above

Streams on athwart the top of the sphere and tends

In same direction as are rolled along

The glittering stars of the eternal world;

Or that another still streams on below

To whirl the sphere from under up and on

In opposite direction- as we see

The rivers turn the wheels and water-scoops.

It may be also that the heavens do all

Remain at rest, whilst yet are borne along

The lucid constellations; either because

Swift tides of ether are by sky enclosed,

And whirl around, seeking a passage out,

And everywhere make roll the starry fires

Through the Summanian regions of the sky;

Or else because some air, streaming along

From an eternal quarter off beyond,

Whileth the driven fires, or, then, because

The fires themselves have power to creep along,

Going wherever their food invites and calls,

And feeding their flaming bodies everywhere

Throughout the sky. Yet which of these is cause

In this our world 'tis hard to say for sure;

But what can be throughout the universe,

In divers worlds on divers plan create,

This only do I show, and follow on

To assign unto the motions of the stars

Even several causes which 'tis possible

Exist throughout the universal All;
