On the Nature of the Universe (Oxford World’s Classics) Page 22

  Would choke with brambles did not man resist,

  Man, for the sake of life well used to groan

  Over strong mattock and cleave earth with plough.

  Unless the ploughshare turn the fruitful clods

  210

  And we, working the soil, bring them to birth,

  No plants can ever of their own accord

  Spring up into the melting air above.

  And even sometimes when with great labour won

  They fill the smiling earth with leaf and flower,

  Either the sun in heaven scorches them

  215

  Or sudden rains destroy them, or chilling frosts,

  And storms with violent whirlwinds harass them.

  Consider now the wild beasts’ fearsome breed,

  Enemies of mankind by land and sea,

  Why does nature feed them? Why do the seasons bring

  220

  Diseases? Why does death untimely stalk abroad?

  And then the child, like sailor cast ashore

  By cruel waves, lies naked on the ground,

  Sans speech, sans all the aids that life requires,

  When nature first into the shores of light

  In throes has cast him from his mother’s womb,

  225

  And fills the place with cries—as well he might

  Seeing that so great ills await his life.

  But flocks and herds and wild beasts live and grow

  Without the aid of rattles; they don’t want

  The baby talk of nurses petting them

  230

  Nor change of clothing with the changing year,

  Nor have they need of arms or lofty walls

  To guard their goods, since earth all things to all

  Brings forth in bounty and nature’s skill supplies.

  Well now, in the first place since earth and water

  235

  And the light breaths of air and burning heat,

  From which we see this sum of things is made—

  Since these have bodies which are born and die,

  Of the whole world we must believe the same.

  For things of which we see that their parts and limbs

  240

  Consist of matter which is born and dies,

  We know that these same things are certainly

  Subject to birth and death. So when I see

  The mighty members of the world consumed

  And born again, why, then I may be sure

  245

  That heaven and earth likewise had their beginning

  And in destruction too will have their end.

  Please do not think that I have begged the question

  When I assume that earth and fire are mortal

  And do not doubt that air and water perish,

  And say that they are born and grow again.

  250

  Take the earth first. A large part of it, burnt

  By constant sun and beaten by myriad feet,

  Breathes out a cloud of dust and flying mists

  Which strong winds scatter abroad all through the air.

  Part of the soil also is washed away

  255

  By rain, and rivers scrape away their banks;

  Besides, whatever the earth throws up returns

  In due proportion; and since beyond doubt we see

  The mother of all to be their common grave,

  Therefore, my friend, you see the earth is diminished

  And then in turn increased and grows again.

  260

  And next, there is no need of words to say

  How sea, rivers, and springs are always full

  With waters new and streams forever flow:

  The mighty fall of waters everywhere

  Makes this quite plain. But the front part of the flood

  Is lifted off and drawn away, and so

  In total there is no excess of water;

  265

  Partly because strong winds sweeping its surface

  Diminish it, and the sun’s high rays unravel it,

  Partly because it seeps through the earth below,

  The brine is filtered off, and the mass of water

  Oozes back and joins the rivers at their source,

  270

  And thence, in a column of sweet water,

  Over the ground it flows along the path

  Cut once by liquid foot to guide the waters.

  Air next I’ll speak of, which throughout its body

  Changes innumerably hour by hour.

  Always whatever flows off from things is carried

  275

  Into the great ocean of the air; unless in turn

  The air gave matter back to things again

  And in their flux created them anew,

  All would by now be dissolved and changed into air.

  Therefore forever air is born from things

  And falls back into things, since it is certain

  That all things are continually in flux.

  280

  The eternal sun, rich fountain of clear light,

  Forever floods the sky with radiance new,

  Swiftly supplying new light in place of old.

  For the first flash of light that comes is lost,

  Wherever it falls. As you may learn from this:

  285

  As soon as clouds begin to front the sun

  And as it were break in between its rays,

  The lower part of them at once is lost,

  And the earth is in shadow, wherever the clouds move;

  So you may see things always need new light,

  290

  That every burst of radiance perishes,

  That in no other way could things be seen

  In sunlight, did the fount of light itself

  Cease ever to maintain a fresh supply.

  And lights that shine at night on earth, these too—

  Your hanging lamps and torches flaming bright,

  295

  Flaring and flashing through the pitchy smoke—

  In the same way, fed by the fire, they haste

  To bring up new supplies of light, and on

  And on they press, alive with flickering flames,

  Seeming to pour an unbroken stream of light;

  So speedily is its extinction hid

  300

  By the swift birth of flame from all the fires.

  So you must think that sun and moon and stars

  Send out quick bursts of light one after another,

  And always the first flash of flame is lost;

  And none of these is indestructible.

  305

  And stones—these too you see that time subdues,

  And lofty towers fall, their masonry

  All crumbling, and the shrines and images

  Of gods, wearied by time, are cracked and fall.

  Nor can their holy power extend the bounds

  Of fate, nor struggle against nature’s laws.

  310

  The monuments of men collapsed we see,

  Should we look there for immortality;

  And rocks roll down, from lofty mountains torn,

  Unable to endure the strong force of time,

  Of finite time. For certainly no shock

  315

  Could make them suddenly break off and fall,

  If from time infinite they had withstood

  Intact the assault and torment of the years.

  Look last at that which above and all around

  Holds the whole earth in its embrace.

  If it is this, as some declare, that makes

  320

  All things from itself and takes them back again

  When their time is finished, it must all consist

  Of matter subject to both birth and death.

  For that which from itself feeds other things

  And nourishes them, must be diminished,


  And made anew when it receives them back.

  Now here’s another point. If earth and sky

  Had no beginning or no time of birth

  325

  But have been always everlasting, why

  Before the Theban war and doom of Troy

  Have other poets not sung other things?

  Where have so many deeds of men so many times

  Fallen from sight and mind, and nowhere flower

  Implanted on eternal monuments?

  In truth I think the world is young and new

  330

  And in quite recent time its life began.

  See even now some arts are being refined

  And others springing up and growing; in ships

  Many new things have now been done, and lately

  Musicians found out tuneful harmonies.

  Yes, and the nature and order of this world

  335

  In recent time has been discovered, and this

  I now myself the very first am found

  Able to tell it in our native tongue.

  But if perchance it may be your belief

  That all these things existed once before,

  But that mankind perished in burning fire

  Or cities fell in some great upheaval of the world,

  340

  Or tearing rivers fed by endless rains

  Flooding the country overwhelmed the towns,

  Why, all the more then you must be convinced

  That earth and sky themselves will be destroyed.

  For when such great afflictions, such great perils,

  345

  Once shook the world, then if some more potent cause

  More terrible had come upon it, there must have followed

  Widespread destruction and a mighty fall.

  And there’s no surer proof of our mortality

  Than this, that we sicken of the same diseases

  As those whom nature has recalled from life.

  350

  Few things there are that last eternally.

  First, solid bodies that repel assaults,

  And allow nothing to penetrate them

  And break apart the close-knit parts within,

  Such as the atomic particles of matter

  The nature of which we have described before;

  355

  Next, things which last through all the length of time

  Because no blow can hit them; such is the void,

  Which stays untouched and nothing can ever strike it;

  Next, things which have no space around them

  Into which they can dissolve and be dispersed;

  360

  Such is the eternal sum of the sum of things.

  Outside it nowhere any place exists

  Into which its elements can spring away,

  And nothing exists to impact it or destroy it.

  363

  But, as I have shown, the world is not composed

  Of solid body, since void is mixed with things.

  365

  Nor is it like the void. Nor are there lacking

  Bodies which from the infinite spring forth

  And rack this world with violent hurricanes

  Or bring some other danger and disaster;

  Nor is there lacking in the depths of space

  370

  Room for the world’s walls fallen to fly apart;

  Or they may perish struck by other force.

  Therefore the door of death is never closed

  To sky and sun and earth and sea’s deep waters.

  No. It stands open, and with vast gaping mouth

  375

  It waits for them.

  Wherefore you must confess that these same things

  Have had their birth; for nothing of mortal build

  Could ever through infinite ages until now

  Have scorned the mighty power of endless time.

  Again, since the mighty members of the world

  380

  So furiously fight among themselves

  In most unrighteous war, do you not see

  Some end to their long struggles may be given?

  Perhaps the sun and universal heat

  Will overcome, and drink the waters dry,

  Which is their aim, though not so far achieved,

  385

  So much the rivers supply and threaten in turn

  To flood the world from ocean’s deep abyss.

  In vain. Since winds that sweep across its surface

  Diminish it, and the sun’s high rays unravel it,

  Confident that they can dry up everything

  390

  Before the waters can achieve their end.

  Such war they breathe in equal combat locked

  Seeking decision in a mighty cause.

  Though once meanwhile fire won the victory,

  And once, so legend tells, water reigned in the fields.

  395

  For fire was lord, and burnt up all around,

  When far from his course the Sun’s fierce horses hurled

  Phaethon through the heavens and o’er the earth.

  But the almighty sire to anger moved

  With sudden thunderbolt the aspiring youth

  400

  Struck from his chariot down to earth. The Sun

  Meeting his fall, caught up the eternal lamp

  That lights the world, brought back the scattered horses,

  Reined them in, trembling, then to their proper courses

  Guiding them back restored the world again.

  At least that’s what the old Greek poets sang,

  405

  And that is very far removed from truth.

  For fire can triumph when from the infinite

  The atoms of its matter issue forth

  In greater mass than usual. And then

  Either subdued somehow its force declines,

  Or the world dies, burnt up by scorching blasts.

  410

  Water likewise began once to prevail,

  Massing its floods, so legend tells, and many

  Races of men were overwhelmed; but then

  That which had massed from out the infinite

  Turned back, by some compelling force withdrawn,

  The rains stopped, and the rivers checked their flow.

  415

  Next in due order I’ll set out the ways

  In which by assembly of matter were established

  The earth, the sky, and the vast depths profound

  Of sea, and courses of the sun and moon.

  For sure, not by design or intelligence

  Did primal atoms place themselves in order,

  420

  Nor did they make contracts, you may be certain,

  As to what movements each of them should make.

  But many primal atoms in many ways

  Moving through infinite time up to the present,

  Clashing among themselves and carried by their own weight,

  Have come together in every possible way,

  Tried every combination that could be made;

  425

  And so advancing through vast lengths of time,

  Exploring every union and motion,

  At length those of them came together

  Which by a sudden conjunction interfused

  Often become the beginnings of great things—

  430

  Of earth and sea and sky and living creatures.

  Then not the sun’s great wheel with bounteous light

  Soaring aloft was seen, nor stars of heaven,

  Nor sea nor sky nor earth at all nor air

  Nor aught like things that in our world we know,

  435

  But a strange storm and surging mighty mass

  Of atoms of all kinds in conflict locked

  Created turmoil, in their intervals

  Connections, courses, weights, blows, meetings, motions,


  Because by reason of their different shapes and patterns

  440

  They could not all when joined together remain so,

  Nor make the movements needed for their union.

  Then parts began to separate, like things

  Joining with like, and parcel out the world,

  Fashion its limbs, set out its mighty parts—

  445

  That is, to set apart high heaven from earth,

  And the sea apart, spreading its separate waters,

  And apart too the pure and separate fires of ether.

  In the first place, all the particles of earth,

  Being heavy and entangled, came together

  450

  In the middle, and took the lowest positions.

  And the more closely mixed they came together

  The more they pressed out elements that could make

  Sea, stars, sun, and moon, and the world’s great walls.

  For all of these consist of elements

  More round and smooth and smaller far than those

  455

  Of earth. First therefore through its porous crust

  Ether broke out and raised itself aloft,

  Ether the fire-bringer, and many fires

  It lightly drew with it. As oft we see

  460

  With blush of morn the golden sun’s new beams

  Colour the meadow grasses pearled with dew,

  And lakes and living streams breathe out a mist,

  And earth itself appears sometimes to smoke;

  And then the vapours forming high above

  465

  Thicken, and weave a web across the sky,

  So in this way then ether light and thin

  Thickened, and bent round curving everywhere

  Expanding everywhere in all directions,

  And thus fenced in the rest with keen embrace.

  470

  Next the beginnings came of sun and moon,

  Whose globes revolve in middle course on high.

  Them neither earth nor mighty ether claimed,

  Being not so heavy as to sink and lie

  Nor light enough to rise through highest heaven,

  475

  But in between they turn as living bodies

  And take their place as parts of all the world;

  As in our bodies too some limbs may stay

  At rest, while others yet are moving.

  And now, when these two orbs had been drawn off,

  480

  Earth suddenly into the wide blue sea

  Sank down, and filled the ditches with salt floods;

  And day by day the more the tides of ether

  And sun’s rays all around beat on the earth,

  And to its farthest bounds with many blows

  485

  Compressed it, so that forced towards its centre

  It became solid, so much then the more

  The salt sweat pressed out oozing from its body

  Increased the sea, increased the swimming plains,

  So much the more slipped out and flew away
