De Rerum Natura

Lucretius

Lucretius. De Rerum Natura. William Ellery Leonard. E. P. Dutton. 1916.

Now, then, of air
I'll speak, which hour by hour in all its body
Is changed innumerably. For whatso'er
Streams up in dust or vapour off of things,
The same is all and always borne along
Into the mighty ocean of the air;
And did not air in turn restore to things
Bodies, and thus recruit them as they stream,
All things by this time had resolved been
And changed into air. Therefore it never
Ceases to be engendered off of things
And to return to things, since verily
In constant flux do all things stream.

Likewise,
The abounding well-spring of the liquid light,
The ethereal sun, doth flood the heaven o'er
With constant flux of radiance ever new,
And with fresh light supplies the place of light,
Upon the instant. For whatever effulgence
Hath first streamed off, no matter where it falls,
Is lost unto the sun. And this 'tis thine
To know from these examples: soon as clouds
Have first begun to under-pass the sun,
And, as it were, to rend the rays of light
In twain, at once the lower part of them
Is lost entire, and earth is overcast
Where'er the thunderheads are rolled along-
So know thou mayst that things forever need
A fresh replenishment of gleam and glow,
And each effulgence, foremost flashed forth,
Perisheth one by one. Nor otherwise
Can things be seen in sunlight, lest alway
The fountain-head of light supply new light.
Indeed your earthly beacons of the night,
The hanging lampions and the torches, bright
With darting gleams and dense with livid soot,
Do hurry in like manner to supply
With ministering heat new light amain;
Are all alive to quiver with their fires,-
Are so alive, that thus the light ne'er leaves
The spots it shines on, as if rent in twain:
So speedily is its destruction veiled
By the swift birth of flame from all the fires.
Thus, then, we must suppose that sun and moon
And stars dart forth their light from under-births
Ever and ever new, and whatso flames
First rise do perish always one by one-
Lest, haply, thou shouldst think they each endure
Inviolable.

Again, perceivest not
How stones are also conquered by Time?-
Not how the lofty towers ruin down,
And boulders crumble?- Not how shrines of gods
And idols crack outworn?- Nor how indeed
The holy Influence hath yet no power
There to postpone the Terminals of Fate,
Or headway make 'gainst Nature's fixed decrees?
Again, behold we not the monuments
Of heroes, now in ruins, asking us,
In their turn likewise, if we don't believe
They also age with eld? Behold we not
The rended basalt ruining amain
Down from the lofty mountains, powerless
To dure and dree the mighty forces there
Of finite time?- for they would never fall
Rended asudden, if from infinite Past
They had prevailed against all engin'ries
Of the assaulting aeons, with no crash.

Again, now look at This, which round, above,
Contains the whole earth in its one embrace:
If from itself it procreates all things-
As some men tell- and takes them to itself
When once destroyed, entirely must it be
Of mortal birth and body; for whate'er
From out itself giveth to other things
Increase and food, the same perforce must be
Minished, and then recruited when it takes
Things back into itself.

Besides all this,
If there had been no origin-in-birth
Of lands and sky, and they had ever been
The everlasting, why, ere Theban war
And obsequies of Troy, have other bards
Not also chanted other high affairs?
Whither have sunk so oft so many deeds
Of heroes? Why do those deeds live no more,
Ingrafted in eternal monuments
Of glory? Verily, I guess, because
The Sum is new, and of a recent date
The nature of our universe, and had
Not long ago its own exordium.
Wherefore, even now some arts are being still
Refined, still increased: now unto ships
Is being added many a new device;
And but the other day musician-folk
Gave birth to melic sounds of organing;
And, then, this nature, this account of things
Hath been discovered latterly, and I
Myself have been discovered only now,
As first among the first, able to turn
The same into ancestral Roman speech.
Yet if, percase, thou deemest that ere this
Existed all things even the same, but that
Perished the cycles of the human race
In fiery exhalations, or cities fell
By some tremendous quaking of the world,
Or rivers in fury, after constant rains,
Had plunged forth across the lands of earth
And whelmed the towns- then, all the more must thou
Confess, defeated by the argument,
That there shall be annihilation too
Of lands and sky. For at a time when things
Were being taxed by maladies so great,
And so great perils, if some cause more fell
Had then assailed them, far and wide they would
Have gone to disaster and supreme collapse.
And by no other reasoning are we
Seen to be mortal, save that all of us
Sicken in turn with those same maladies
With which have sickened in the past those men
Whom nature hath removed from life.

Again,
Whatever abides eternal must indeed
Either repel all strokes, because 'tis made
Of solid body, and permit no entrance
Of aught with power to sunder from within
The parts compact- as are those seeds of stuff
Whose nature we've exhibited before;
Or else be able to endure through time
For this: because they are from blows exempt,
As is the void, the which abides untouched,
Unsmit by any stroke; or else because
There is no room around, whereto things can,
As 'twere, depart in dissolution all,-
Even as the sum of sums eternal is,
Without or place beyond whereto things may
Asunder fly, or bodies which can smite,
And thus dissolve them by the blows of might.
But not of solid body, as I've shown,
Exists the nature of the world, because
In things is intermingled there a void;
Nor is the world yet as the void, nor are,
Moreover, bodies lacking which, percase,
Rising from out the infinite, can fell
With fury-whirlwinds all this sum of things,
Or bring upon them other cataclysm
Of peril strange; and yonder, too, abides
The infinite space and the profound abyss-
Whereinto, lo, the ramparts of the world
Can yet be shivered. Or some other power
Can pound upon them till they perish all.
Thus is the door of doom, O nowise barred
Against the sky, against the sun and earth
And deep-sea waters, but wide open stands
And gloats upon them, monstrous and agape.
Wherefore, again, 'tis needful to confess
That these same things are born in time; for things
Which are of mortal body could indeed
Never from infinite past until to-day
Have spurned the multitudinous assaults
Of the immeasurable aeons old.
