On the Nature of Things · Lucretius
But in what modes that conflux of first-stuff
Did found the multitudinous universe
Of earth, and sky, and the unfathomed deeps
Of ocean, and courses of the sun and moon,
I'll now in order tell. For of a truth
Neither by counsel did the primal germs
'Stablish themselves, as by keen act of mind,
Each in its proper place; nor did they make,
Forsooth, a compact how each germ should move;
But, lo, because primordials of things,
Many in many modes, astir by blows
From immemorial aeons, in motion too
By their own weights, have evermore been wont
To be so borne along and in all modes
To meet together and to try all sorts
Which, by combining one with other, they
Are powerful to create: because of this
It comes to pass that those primordials,
Diffused far and wide through mighty aeons,
The while they unions try, and motions too,
Of every kind, meet at the last amain,
And so become oft the commencements fit
Of mighty things--earth, sea, and sky, and race
Of living creatures.
In that long-ago
The wheel of the sun could nowhere be discerned
Flying far up with its abounding blaze,
Nor constellations of the mighty world,
Nor ocean, nor heaven, nor even earth nor air.
Nor aught of things like unto things of ours
Could then be seen--but only some strange storm
And a prodigious hurly-burly mass
Compounded of all kinds of primal germs,
Whose battling discords in disorder kept
Interstices, and paths, coherencies,
And weights, and blows, encounterings, and motions,
Because, by reason of their forms unlike
And varied shapes, they could not all thuswise
Remain conjoined nor harmoniously
Have interplay of movements. But from there
Portions began to fly asunder, and like
With like to join, and to block out a world,
And to divide its members and dispose
Its mightier parts--that is, to set secure
The lofty heavens from the lands, and cause
The sea to spread with waters separate,
And fires of ether separate and pure
Likewise to congregate apart.
For, lo,
First came together the earthy particles
(As being heavy and intertangled) there
In the mid-region, and all began to take
The lowest abodes; and ever the more they got
One with another intertangled, the more
They pressed from out their mass those particles
Which were to form the sea, the stars, the sun,
And moon, and ramparts of the mighty world--
For these consist of seeds more smooth and round
And of much smaller elements than earth.
And thus it was that ether, fraught with fire,
First broke away from out the earthen parts,
Athrough the innumerable pores of earth,
And raised itself aloft, and with itself
Bore lightly off the many starry fires;
And not far otherwise we often see
And the still lakes and the perennial streams
Exhale a mist, and even as earth herself
Is seen at times to smoke, when first at dawn
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.
And that the earth may there abide at rest
In the mid-region of the world, it needs
Must vanish bit by bit in weight and lessen,
And have another substance underneath,
Conjoined to it from its earliest age
In linked unison with the vasty world's
Realms of the air in which it roots and lives.
On this account, the earth is not a load,
Nor presses down on winds of air beneath;
Even as unto a man his members be
Without all weight--the head is not a load
Unto the neck; nor do we feel the whole
Weight of the body to centre in the feet.
But whatso weights come on us from without,
Weights laid upon us, these harass and chafe,
Though often far lighter. For to such degree
It matters always what the innate powers
Of any given thing may be. The earth
Was, then, no alien substance fetched amain,
And from no alien firmament cast down
On alien air; but was conceived, like air,
In the first origin of this the world,
As a fixed portion of the same, as now
Our members are seen to be a part of us.
Besides, the earth, when of a sudden shook
By the big thunder, doth with her motion shake
All that's above her--which she ne'er could do
By any means, were earth not bounden fast
Unto the great world's realms of air and sky:
For they cohere together with common roots,
Conjoined both, even from their earliest age,
In linked unison. Aye, seest thou not
That this most subtle energy of soul
Supports our body, though so heavy a weight,--
Because, indeed, 'tis with it so conjoined
In linked unison? What power, in sum,
Can raise with agile leap our body aloft,
Save energy of mind which steers the limbs?
Now seest thou not how powerful may be
A subtle nature, when conjoined it is
With heavy body, as air is with the earth
Conjoined, and energy of mind with us?
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;
Of which yet one must be the cause even here
Which maketh motion for our constellations.
Yet to decide which one of them it be
Is not the least the business of a man
Advancing step by cautious step, as I.
Nor can the sun's wheel larger be by much
Nor its own blaze much less than either seems
Unto our senses. For from whatso spaces
Fires have the power on us to cast their beams
And blow their scorching exhalations forth
Against our members, those same distances
Take nothing by those intervals away
From bulk of flames; and to the sight the fire
Is nothing shrunken. Therefore, since the heat
And the outpoured light of skiey sun
Arrive our senses and caress our limbs,
Form too and bigness of the sun must look
Even here from earth just as they really be,
So that thou canst scarce nothing take or add.
And whether the journeying moon illuminate
The regions round with bastard beams, or throw
From off her proper body her own light,--
Whichever it be, she journeys with a form
Naught larger than the form doth seem to be
Which we with eyes of ours perceive. For all
The far removed objects of our gaze
Seem through much air confused in their look
Ere minished in their bigness. Wherefore, moon,
Since she presents bright look and clear-cut form,
May there on high by us on earth be seen
Just as she is with extreme bounds defined,
And just of the size. And lastly, whatso fires
Of ether thou from earth beholdest, these
Thou mayst consider as possibly of size
The least bit less, or larger by a hair
Than they appear--since whatso fires we view
Here in the lands of earth are seen to change
From time to time their size to less or more
Only the least, when more or less away,
So long as still they bicker clear, and still
Their glow's perceived.
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?
