De Rerum Natura

Lucretius

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

Nor need there be for men
Astonishment that yonder sun so small
Can yet send forth so great a light as fills
Oceans and all the lands and sky aflood,
And with its fiery exhalations steeps
The world at large. For it may be, indeed,
That one vast-flowing well-spring of the whole
Wide world from here hath opened and out-gushed,
And shot its light abroad; because thuswise
The elements of fiery exhalations
From all the world around together come,
And thuswise flow into a bulk so big
That from one single fountain-head may stream
This heat and light. And seest thou not, indeed,
How widely one small water-spring may wet
The meadow-lands at times and flood the fields?
'Tis even possible, besides, that heat
From forth the sun's own fire, albeit that fire
Be not a great, may permeate the air
With the fierce hot- if but, perchance, the air
Be of condition and so tempered then
As to be kindled, even when beat upon
Only by little particles of heat-
Just as we sometimes see the standing grain
Or stubble straw in conflagration all
From one lone spark. And possibly the sun,
Agleam on high with rosy lampion,
Possesses about him with invisible heats
A plenteous fire, by no effulgence marked,
So that he maketh, he, the Fraught-with-fire,
Increase to such degree the force of rays.

Nor is there one sure cause revealed to men
How the sun journeys from his summer haunts
On to the mid-most winter turning-points
In Capricorn, the thence reverting veers
Back to solstitial goals of Cancer; nor
How 'tis the moon is seen each month to cross
That very distance which in traversing
The sun consumes the measure of a year.
I say, no one clear reason hath been given
For these affairs. Yet chief in likelihood
Seemeth the doctrine which the holy thought
Of great Democritus lays down: that ever
The nearer the constellations be to earth
The less can they by whirling of the sky
Be borne along, because those skiey powers
Of speed aloft do vanish and decrease
In under-regions, and the sun is thus
Left by degrees behind amongst those signs
That follow after, since the sun he lies
Far down below the starry signs that blaze;
And the moon lags even tardier than the sun:
In just so far as is her course removed
From upper heaven and nigh unto the lands,
In just so far she fails to keep the pace
With starry signs above; for just so far
As feebler is the whirl that bears her on,
(Being, indeed, still lower than the sun),
In just so far do all the starry signs,
Circling around, o'ertake her and o'erpass.
Therefore it happens that the moon appears
More swiftly to return to any sign
Along the Zodiac, than doth the sun,
Because those signs do visit her again
More swiftly than they visit the great sun.
It can be also that two streams of air
Alternately at fixed periods
Blow out from transverse regions of the world,
Of which the one may thrust the sun away
From summer-signs to mid-most winter goals
And rigors of the cold, and the other then
May cast him back from icy shades of chill
Even to the heat-fraught regions and the signs
That blaze along the Zodiac. So, too,
We must suppose the moon and all the stars,
Which through the mighty and sidereal years
Roll round in mighty orbits, may be sped
By streams of air from regions alternate.
Seest thou not also how the clouds be sped
By contrary winds to regions contrary,
The lower clouds diversely from the upper?
Then, why may yonder stars in ether there
Along their mighty orbits not be borne
By currents opposite the one to other?

But night o'erwhelms the lands with vasty murk
Either when sun, after his diurnal course,
Hath walked the ultimate regions of the sky
And wearily hath panted forth his fires,
Shivered by their long journeying and wasted
By traversing the multitudinous air,
Or else because the self-same force that drave
His orb along above the lands compels
Him then to turn his course beneath the lands.
Matuta also at a fixed hour
Spreadeth the roseate morning out along
The coasts of heaven and deploys the light,
Either because the self-same sun, returning
Under the lands, aspires to seize the sky,
Striving to set it blazing with his rays
Ere he himself appear, or else because
Fires then will congregate and many seeds
Of heat are wont, even at a fixed time,
To stream together- gendering evermore
New suns and light. Just so the story goes
That from the Idaean mountain-tops are seen
Dispersed fires upon the break of day
Which thence combine, as 'twere, into one ball
And form an orb. Nor yet in these affairs
Is aught for wonder that these seeds of fire
Can thus together stream at time so fixed
And shape anew the splendour of the sun.
For many facts we see which come to pass
At fixed time in all things: burgeon shrubs
At fixed time, and at a fixed time
They cast their flowers; and Eld commands the teeth,
At time as surely fixed, to drop away,
And Youth commands the growing boy to bloom
With the soft down and let from both his cheeks
The soft beard fall. And lastly, thunder-bolts,
Snow, rains, clouds, winds, at seasons of the year
Nowise unfixed, all do come to pass.
For where, even from their old primordial start
Causes have ever worked in such a way,
And where, even from the world's first origin,
Thuswise have things befallen, so even now
After a fixed order they come round
In sequence also.

Likewise, days may wax
Whilst the nights wane, and daylight minished be
Whilst nights do take their augmentations,
Either because the self-same sun, coursing
Under the lands and over in two arcs,
A longer and a briefer, doth dispart
The coasts of ether and divides in twain
His orbit all unequally, and adds,
As round he's borne, unto the one half there
As much as from the other half he's ta'en,
Until he then arrives that sign of heaven
Where the year's node renders the shades of night
Equal unto the periods of light.
For when the sun is midway on his course
Between the blasts of northwind and of south,
Heaven keeps his two goals parted equally,
By virtue of the fixed position old
Of the whole starry Zodiac, through which
That sun, in winding onward, takes a year,
Illumining the sky and all the lands
With oblique light- as men declare to us
Who by their diagrams have charted well
Those regions of the sky which be adorned
With the arranged signs of Zodiac.
Or else, because in certain parts the air
Under the lands is denser, the tremulous
Bright beams of fire do waver tardily,
Nor easily can penetrate that air
Nor yet emerge unto their rising-place:
For this it is that nights in winter time
Do linger long, ere comes the many-rayed
Round Badge of the day. Or else because, as said,
In alternating seasons of the year
Fires, now more quick, and now more slow, are wont
To stream together,- the fires which make the sun
To rise in some one spot- therefore it is
That those men seem to speak the truth [who hold
A new sun is with each new daybreak born].

The moon she possibly doth shine because
Strook by the rays of sun, and day by day
May turn unto our gaze her light, the more
She doth recede from orb of sun, until,
Facing him opposite across the world,
She hath with full effulgence gleamed abroad,
And, at her rising as she soars above,
Hath there observed his setting; thence likewise
She needs must hide, as 'twere, her light behind
By slow degrees, the nearer now she glides,
Along the circle of the Zodiac,
From her far place toward fires of yonder sun,-
As those men hold who feign the moon to be
Just like a ball and to pursue a course
Betwixt the sun and earth. There is, again,
Some reason to suppose that moon may roll
With light her very own, and thus display
The varied shapes of her resplendence there.
For near her is, percase, another body,
Invisible, because devoid of light,
Borne on and gliding all along with her,
Which in three modes may block and blot her disk.
Again, she may revolve upon herself,
Like to a ball's sphere- if perchance that be-
One half of her dyed o'er with glowing light,
And by the revolution of that sphere
She may beget for us her varying shapes,
Until she turns that fiery part of her
Full to the sight and open eyes of men;
Thence by slow stages round and back she whirls,
Withdrawing thus the luminiferous part
Of her sphered mass and ball, as, verily,
The Babylonian doctrine of Chaldees,
Refuting the art of Greek astrologers,
Labours, in opposition, to prove sure-
As if, forsooth, the thing for which each fights,
Might not alike be true,- or aught there were
Wherefore thou mightest risk embracing one
More than the other notion. Then, again,
Why a new moon might not forevermore
Created be with fixed successions there
Of shapes and with configurations fixed,
And why each day that bright created moon
Might not miscarry and another be,
In its stead and place, engendered anew,
'Tis hard to show by reason, or by words
To prove absurd- since, lo, so many things
Can be create with fixed successions:
Spring-time and Venus come, and Venus' boy,
The winged harbinger, steps on before,
And hard on Zephyr's foot-prints Mother Flora,
Sprinkling the ways before them, filleth all
With colours and with odours excellent;
Whereafter follows arid Heat, and he
Companioned is by Ceres, dusty one,
And by the Etesian Breezes of the north;
Then cometh Autumn on, and with him steps
Lord Bacchus, and then other Seasons too
And other Winds do follow- the high roar
Of great Volturnus, and the Southwind strong
With thunder-bolts. At last earth's Shortest-Day
Bears on to men the snows and brings again
The numbing cold. And Winter follows her,
His teeth with chills a-chatter. Therefore, 'tis
The less a marvel, if at fixed time
A moon is thus begotten and again
At fixed time destroyed, since things so many
Can come to being thus at fixed time.
Likewise, the sun's eclipses and the moon's
Far occultations rightly thou mayst deem

As due to several causes. For, indeed,
Why should the moon be able to shut out
Earth from the light of sun, and on the side
To earthward thrust her high head under sun,
Opposing dark orb to his glowing beams-
And yet, at same time, one suppose the effect
Could not result from some one other body
Which glides devoid of light forevermore?
Again, why could not sun, in weakened state,
At fixed time for-lose his fires, and then,
When he has passed on along the air
Beyond the regions, hostile to his flames,
That quench and kill his fires, why could not he
Renew his light? And why should earth in turn
Have power to rob the moon of light, and there,
Herself on high, keep the sun hid beneath,
Whilst the moon glideth in her monthly course
Athrough the rigid shadows of the cone?-
And yet, at same time, some one other body
Not have the power to under-pass the moon,
Or glide along above the orb of sun,
Breaking his rays and outspread light asunder?
And still, if moon herself refulgent be
With her own sheen, why could she not at times
In some one quarter of the mighty world
Grow weak and weary, whilst she passeth through
Regions unfriendly to the beams her own?

And now to what remains!- Since I've resolved
By what arrangements all things come to pass
Through the blue regions of the mighty world,-
How we can know what energy and cause
Started the various courses of the sun
And the moon's goings, and by what far means
They can succumb, the while with thwarted light,
And veil with shade the unsuspecting lands,
When, as it were, they blink, and then again
With open eye survey all regions wide,
Resplendent with white radiance- I do now
Return unto the world's primeval age
And tell what first the soft young fields of earth
With earliest parturition had decreed
To raise in air unto the shores of light
And to entrust unto the wayward winds.
In the beginning, earth gave forth, around
The hills and over all the length of plains,
The race of grasses and the shining green;
The flowery meadows sparkled all aglow
With greening colour, and thereafter, lo,
Unto the divers kinds of trees was given
An emulous impulse mightily to shoot,
With a free rein, aloft into the air.
As feathers and hairs and bristles are begot
The first on members of the four-foot breeds
And on the bodies of the strong-y-winged,
Thus then the new Earth first of all put forth
Grasses and shrubs, and afterward begat
The mortal generations, there upsprung-
Innumerable in modes innumerable-
After diverging fashions. For from sky
These breathing-creatures never can have dropped,
Nor the land-dwellers ever have come up
Out of sea-pools of salt. How true remains,
How merited is that adopted name
Of earth- "The Mother!"- since from out the earth
Are all begotten. And even now arise
From out the loams how many living things-
Concreted by the rains and heat of the sun.
Wherefore 'tis less a marvel, if they sprang
In Long Ago more many, and more big,
Matured of those days in the fresh young years
Of earth and ether. First of all, the race
Of the winged ones and parti-coloured birds,
Hatched out in spring-time, left their eggs behind;
As now-a-days in summer tree-crickets
Do leave their shiny husks of own accord,
Seeking their food and living. Then it was
This earth of thine first gave unto the day
The mortal generations; for prevailed
Among the fields abounding hot and wet.
And hence, where any fitting spot was given,
There 'gan to grow womb-cavities, by roots
Affixed to earth. And when in ripened time
The age of the young within (that sought the air
And fled earth's damps) had burst these wombs, O then
Would Nature thither turn the pores of earth
And make her spurt from open veins a juice
Like unto milk; even as a woman now
Is filled, at child-bearing, with the sweet milk,
Because all that swift stream of aliment
Is thither turned unto the mother-breasts.
There earth would furnish to the children food;
Warmth was their swaddling cloth, the grass their bed
Abounding in soft down. Earth's newness then
Would rouse no dour spells of the bitter cold,
Nor extreme heats nor winds of mighty powers-
For all things grow and gather strength through time
In like proportions; and then earth was young.

Wherefore, again, again, how merited
Is that adopted name of Earth- The Mother!-
Since she herself begat the human race,
And at one well-nigh fixed time brought forth
Each breast that ranges raving round about
Upon the mighty mountains and all birds
Aerial with many a varied shape.
But, lo, because her bearing years must end,
She ceased, like to a woman worn by eld.
For lapsing aeons change the nature of
The whole wide world, and all things needs must take
One status after other, nor aught persists
Forever like itself. All things depart;
Nature she changeth all, compelleth all
To transformation. Lo, this moulders down,
A-slack with weary eld, and that, again,
Prospers in glory, issuing from contempt.
In suchwise, then, the lapsing aeons change
The nature of the whole wide world, and earth
Taketh one status after other. And what
She bore of old, she now can bear no longer,
And what she never bore, she can to-day.
In those days also the telluric world
Strove to beget the monsters that upsprung
With their astounding visages and limbs-
The Man-woman- a thing betwixt the twain,
Yet neither, and from either sex remote-
Some gruesome Boggles orphaned of the feet,
Some widowed of the hands, dumb Horrors too
Without a mouth, or blind Ones of no eye,
Or Bulks all shackled by their legs and arms
Cleaving unto the body fore and aft,
Thuswise, that never could they do or go,
Nor shun disaster, nor take the good they would.
And other prodigies and monsters earth
Was then begetting of this sort- in vain,
Since Nature banned with horror their increase,
And powerless were they to reach unto
The coveted flower of fair maturity,
Or to find aliment, or to intertwine
In works of Venus. For we see there must
Concur in life conditions manifold,
If life is ever by begetting life
To forge the generations one by one:
First, foods must be; and, next, a path whereby
The seeds of impregnation in the frame
May ooze, released from the members all;
Last, the possession of those instruments
Whereby the male with female can unite,
The one with other in mutual ravishments.

And in the ages after monsters died,
Perforce there perished many a stock, unable
By propagation to forge a progeny.
For whatsoever creatures thou beholdest
Breathing the breath of life, the same have been
Even from their earliest age preserved alive
By cunning, or by valour, or at least
By speed of foot or wing. And many a stock
Remaineth yet, because of use to man,
And so committed to man's guardianship.
Valour hath saved alive fierce lion-breeds
And many another terrorizing race,
Cunning the foxes, flight the antlered stags.
Light-sleeping dogs with faithful heart in breast,
However, and every kind begot from seed
Of beasts of draft, as, too, the woolly flocks
And horned cattle, all, my Memmius,
Have been committed to guardianship of men.
For anxiously they fled the savage beasts,
And peace they sought and their abundant foods,
Obtained with never labours of their own,
Which we secure to them as fit rewards
For their good service. But those beasts to whom
Nature has granted naught of these same things-
Beasts quite unfit by own free will to thrive
And vain for any service unto us
In thanks for which we should permit their kind
To feed and be in our protection safe-
Those, of a truth, were wont to be exposed,
Enshackled in the gruesome bonds of doom,
As prey and booty for the rest, until
Nature reduced that stock to utter death.
