In chief, men marvel nature renders not
Bigger and bigger the bulk of ocean, since
So vast the down-rush of the waters be,
And every river out of every realm
Cometh thereto; and add the random rains
And flying tempests, which spatter every sea
And every land bedew; add their own springs:
Yet all of these unto the ocean's sum
Shall be but as the increase of a drop.
Wherefore 'tis less a marvel that the sea,
The mighty ocean, increaseth not. Besides,
Sun with his heat draws off a mighty part:
Yea, we behold that sun with burning beams
To dry our garments dripping all with wet;
And many a sea, and far out-spread beneath,
Do we behold. Therefore, however slight
The portion of wet that sun on any spot
Culls from the level main, he still will take
From off the waves in such a wide expanse
Abundantly. Then, further, also winds,
Sweeping the level waters, can bear off
A mighty part of wet, since we behold
Oft in a single night the highways dried
By winds, and soft mud crusted o'er at dawn.
Again, I've taught thee that the clouds bear off
Much moisture too, up-taken from the reaches
Of the mighty main, and sprinkle it about
O'er all the zones, when rain is on the lands
And winds convey the aery racks of vapour.
Lastly, since earth is porous through her frame,
And neighbours on the seas, girdling their shores,
The water's wet must seep into the lands
From briny ocean, as from lands it comes
Into the seas. For brine is filtered off,
And then the liquid stuff seeps back again
And all re-poureth at the river-heads,
Whence in fresh-water currents it returns
Over the lands, adown the channels which
Were cleft erstwhile and erstwhile bore along
The liquid-footed floods.
  And now the cause
Whereby athrough the throat of Aetna's Mount
Such vast tornado-fires out-breathe at times,
I will unfold: for with no middling might
Of devastation the flamy tempest rose
And held dominion in Sicilian fields:
Drawing upon itself the upturned faces
Of neighbouring clans, what time they saw afar
The skiey vaults a-fume and sparkling all,
And filled their bosoms with dread anxiety
Of what new thing nature were travailing at.
  In these affairs it much behooveth thee
To look both wide and deep, and far abroad
To peer to every quarter, that thou mayst
Remember how boundless is the Sum-of-Things,
And mark how infinitely small a part
Of the whole Sum is this one sky of ours-
O not so large a part as is one man
Of the whole earth. And plainly if thou viewest
This cosmic fact, placing it square in front,
And plainly understandest, thou wilt leave
Wondering at many things. For who of us
Wondereth if some one gets into his joints
A fever, gathering head with fiery heat,
Or any other dolorous disease
Along his members? For anon the foot
Grows blue and bulbous; often the sharp twinge
Seizes the teeth, attacks the very eyes;
Out-breaks the sacred fire, and, crawling on
Over the body, burneth every part
It seizeth on, and works its hideous way
Along the frame. No marvel this, since, lo,
Of things innumerable be seeds enough,
And this our earth and sky do bring to us
Enough of bane from whence can grow the strength
Of maladies uncounted. Thuswise, then,
We must suppose to all the sky and earth
Are ever supplied from out the infinite
All things, O all in stores enough whereby
The shaken earth can of a sudden move,
And fierce typhoons can over sea and lands
Go tearing on, and Aetna's fires o'erflow,
And heaven become a flame-burst. For that, too,
Happens at times, and the celestial vaults
Glow into fire, and rainy tempests rise
In heavier congregation, when, percase,
The seeds of water have foregathered thus
From out the infinite. "Aye, but passing huge
The fiery turmoil of that conflagration!"
So sayst thou; well, huge many a river seems
To him that erstwhile ne'er a larger saw;
Thus, huge seems tree or man; and everything
Which mortal sees the biggest of each class,
That he imagines to be "huge"; though yet
All these, with sky and land and sea to boot,
Are all as nothing to the sum entire
Of the all-Sum.
  But now I will unfold
At last how yonder suddenly angered flame
Out-blows abroad from vasty furnaces
Aetnaean. First, the mountain's nature is
All under-hollow, propped about, about
With caverns of basaltic piers. And, lo,
In all its grottos be there wind and air-
For wind is made when air hath been uproused
By violent agitation. When this air
Is heated through and through, and, raging round,
Hath made the earth and all the rocks it touches
Horribly hot, and hath struck off from them
Fierce fire of swiftest flame, it lifts itself
And hurtles thus straight upwards through its throat
Into high heav'n, and thus bears on afar
Its burning blasts and scattereth afar
Its ashes, and rolls a smoke of pitchy murk
And heaveth the while boulders of wondrous weight-
Leaving no doubt in thee that 'tis the air's
Tumultuous power. Besides, in mighty part,
The sea there at the roots of that same mount
Breaks its old billows and sucks back its surf.
And grottos from the sea pass in below
Even to the bottom of the mountain's throat.
Herethrough thou must admit there go…
  .  .  .  .  .  .
And the conditions force [the water and air]
Deeply to penetrate from the open sea,
And to out-blow abroad, and to up-bear
Thereby the flame, and to up-cast from deeps
The boulders, and to rear the clouds of sand.
For at the top be "bowls," as people there
Are wont to name what we at Rome do call
The throats and mouths.
  There be, besides, some thing
Of which 'tis not enough one only cause
To state- but rather several, whereof one
Will be the true: lo, if thou shouldst espy
Lying afar some fellow's lifeless corse,
'Twere meet to name all causes of a death,
That cause of his death might thereby be named:
For prove thou mayst he perished not by steel,
By cold, nor even by poison nor disease,
Yet somewhat of this sort hath come to him
We know- And thus we have to say the same
In divers cases.
  Toward the summer, Nile
Waxeth and overfloweth the champaign,
Unique in all the landscape, river sole
Of the Aegyptians. In mid-season heats
Often and oft he waters Aegypt o'er,
Either because in summer against his mouths
Come those northwinds which at that time of year
Men name the Etesian blasts, and, blowing thus
Upstream, retard, and, forcing back his waves,
Fill him o'erfull and force his flow to stop.
For out of doubt these blasts which driven be
From icy constellations of the pole
Are borne straight up the river. Comes that river
From forth the sultry places down the south,
Rising far up in midmost realm of day,
Among black generations of strong men
With sun-baked skins. 'Tis possible, besides,
That a big bulk of piled sand may bar
His mouths against his onward waves, when sea,
Wild in the winds, tumbles the sand to inland;
Whereby the river's outlet were less free,
Likewise less headlong his descending floods.
It may be, too, that in this season rains
Are more abundant at its fountain head,
Because the Etesian blasts of those northwinds
Then urge all clouds into those inland parts.
And, soothly, when they're thus foregathered there,
Urged yonder into midmost realm of day,
Then, crowded against the lofty mountain sides,
They're massed and powerfully pressed. Again,
Perchance, his waters wax, O far away,
Among the Aethiopians' lofty mountains,
When the all-beholding sun with thawing beams
Drives the white snows to flow into the vales.
  Now come; and unto thee I will unfold,
As to the Birdless spots and Birdless tarns,
What sort of nature they are furnished with.
First, as to name of "birdless,"- that derives
From very fact, because they noxious be
Unto all birds. For when above those spots
In horizontal flight the birds have come,
Forgetting to oar with wings, they furl their sails,
And, with down-drooping of their delicate necks,
Fall headlong into earth, if haply such
The nature of the spots, or into water,
If haply spreads thereunder Birdless tarn.
Such spot's at Cumae, where the mountains smoke,
Charged with the pungent sulphur, and increased
With steaming springs. And such a spot there is
Within the walls of Athens, even there
On summit of Acropolis, beside
Fane of Tritonian Pallas bountiful,
Where never cawing crows can wing their course,
Not even when smoke the altars with good gifts,-
But evermore they flee- yet not from wrath
Of Pallas, grieved at that espial old,
As poets of the Greeks have sung the tale;
But very nature of the place compels.
In Syria also- as men say- a spot
Is to be seen, where also four-foot kinds,
As soon as ever they've set their steps within,
Collapse, o'ercome by its essential power,
As if there slaughtered to the under-gods.
Lo, all these wonders work by natural law,
And from what causes they are brought to pass
The origin is manifest; so, haply,
Let none believe that in these regions stands
The gate of Orcus, nor us then suppose,
Haply, that thence the under-gods draw down
Souls to dark shores of Acheron- as stags,
The wing-footed, are thought to draw to light,
By sniffing nostrils, from their dusky lairs
The wriggling generations of wild snakes.
How far removed from true reason is this,
Perceive thou straight; for now I'll try to say
Somewhat about the very fact.
  And, first,
This do I say, as oft I've said before:
In earth are atoms of things of every sort;
And know, these all thus rise from out the earth-
Many life-giving which be good for food,
And many which can generate disease
And hasten death, O many primal seeds
Of many things in many modes- since earth
Contains them mingled and gives forth discrete.
And we have shown before that certain things
Be unto certain creatures suited more
For ends of life, by virtue of a nature,
A texture, and primordial shapes, unlike
For kinds alike. Then too 'tis thine to see
How many things oppressive be and foul
To man, and to sensation most malign:
Many meander miserably through ears;
Many in-wind athrough the nostrils too,
Malign and harsh when mortal draws a breath;
Of not a few must one avoid the touch;
Of not a few must one escape the sight;
And some there be all loathsome to the taste;
And many, besides, relax the languid limbs
Along the frame, and undermine the soul
In its abodes within. To certain trees
There hath been given so dolorous a shade
That often they gender achings of the head,
If one but be beneath, outstretched on the sward.
There is, again, on Helicon's high hills
A tree that's wont to kill a man outright
By fetid odour of its very flower.
And when the pungent stench of the night-lamp,
Extinguished but a moment since, assails
The nostrils, then and there it puts to sleep
A man afflicted with the falling sickness
And foamings at the mouth. A woman, too,
At the heavy castor drowses back in chair,
And from her delicate fingers slips away
Her gaudy handiwork, if haply she
Hath got the whiff at menstruation-time.
Once more, if thou delayest in hot baths,
When thou art over-full, how readily
From stool in middle of the steaming water
Thou tumblest in a fit! How readily
The heavy fumes of charcoal wind their way
Into the brain, unless beforehand we
Of water 've drunk. But when a burning fever,
O'ermastering man, hath seized upon his limbs,
Then odour of wine is like a hammer-blow.
And seest thou not how in the very earth
Sulphur is gendered and bitumen thickens
With noisome stench?- What direful stenches, too,
Scaptensula out-breathes from down below,
When men pursue the veins of silver and gold,
With pick-axe probing round the hidden realms
Deep in the earth?- Or what of deadly bane
The mines of gold exhale? O what a look,
And what a ghastly hue they give to men!
And seest thou not, or hearest, how they're wont
In little time to perish, and how fail
The life-stores in those folk whom mighty power
Of grim necessity confineth there
In such a task? Thus, this telluric earth
Out-streams with all these dread effluvia
And breathes them out into the open world
And into the visible regions under heaven.
  Thus, too, those Birdless places must up-send
An essence bearing death to winged things,
Which from the earth rises into the breezes
To poison part of skiey space, and when
Thither the winged is on pennons borne,
There, seized by the unseen poison, 'tis ensnared,
And from the horizontal of its flight
Drops to the spot whence sprang the effluvium.
And when 'thas there collapsed, then the same power
Of that effluvium takes from all its limbs
The relics of its life. That power first strikes
The creatures with a wildering dizziness,
And then thereafter, when they're once down-fallen
Into the poison's very fountains, then
Life, too, they vomit out perforce, because
So thick the stores of bane around them fume.
  Again, at times it happens that this power,
This exhalation of the Birdless places,
Dispels the air betwixt the ground and birds,
Leaving well-nigh a void. And thither when
In horizontal flight the birds have come,
Forthwith their buoyancy of pennons limps,
All useless, and each effort of both wings
Falls out in vain. Here, when without all power
To buoy themselves and on their wings to lean,
Lo, nature constrains them by their weight to slip
Down to the earth, and lying prostrate there
Along the well-nigh empty void, they spend
Their souls through all the openings of their frame.
  .  .  .  .  .  .
  Further, the water of wells is colder then
At summer time, because the earth by heat
Is rarefied, and sends abroad in air
Whatever seeds it peradventure have
Of its own fiery exhalations.
The more, then, the telluric ground is drained
Of heat, the colder grows the water hid
Within the earth. Further, when all the earth
Is by the cold compressed, and thus contracts
And, so to say, concretes, it happens, lo,
That by contracting it expresses then
Into the wells what heat it bears itself.
  'Tis said at Hammon's fane a fountain is,
In daylight cold and hot in time of night.
This fountain men be-wonder over-much,
And think that suddenly it seethes in heat
By intense sun, the subterranean, when
Night with her terrible murk hath cloaked the lands-
What's not true reasoning by a long remove:
I' faith when sun o'erhead, touching with beams
An open body of water, had no power
To render it hot upon its upper side,
Though his high light possess such burning glare,
How, then, can he, when under the gross earth,
Make water boil and glut with fiery heat?-
And, specially, since scarcely potent he
Through hedging walls of houses to inject
His exhalations hot, with ardent rays.
What, then's, the principle? Why, this, indeed:
The earth about that spring is porous more
Than elsewhere the telluric ground, and be
Many the seeds of fire hard by the water;
On this account, when night with dew-fraught shades
Hath whelmed the earth, anon the earth deep down
Grows chill, contracts; and thuswise squeezes out
Into the spring what seeds she holds of fire
(As one might squeeze with fist), which render hot
The touch and steam of the fluid. Next, when sun,
Up-risen, with his rays has split the soil
And rarefied the earth with waxing heat,
Again into their ancient abodes return
The seeds of fire, and all the Hot of water
Into the earth retires; and this is why
The fountain in the daylight gets so cold.
Besides, the water's wet is beat upon
By rays of sun, and, with the dawn, becomes
Rarer in texture under his pulsing blaze;
And, therefore, whatso seeds it holds of fire
It renders up, even as it renders oft
The frost that it contains within itself
And thaws its ice and looseneth the knots.
There is, moreover, a fountain cold in kind
That makes a bit of tow (above it held)
Take fire forthwith and shoot a flame; so, too,
A pitch-pine torch will kindle and flare round
Along its waves, wherever 'tis impelled
Afloat before the breeze. No marvel, this:
Because full many seeds of heat there be
Within the water; and, from earth itself
Out of the deeps must particles of fire
Athrough the entire fountain surge aloft,
And speed in exhalations into air
Forth and abroad (yet not in numbers enow
As to make hot the fountain). And, moreo'er,
Some force constrains them, scattered through the water,
Forthwith to burst abroad, and to combine
In flame above. Even as a fountain far
There is at Aradus amid the sea,
Which bubbles out sweet water and disparts
From round itself the salt waves; and, behold,
In many another region the broad main
Yields to the thirsty mariners timely help,
Belching sweet waters forth amid salt waves.
Just so, then, can those seeds of fire burst forth
Athrough that other fount, and bubble out
Abroad against the bit of tow; and when
They there collect or cleave unto the torch,
Forthwith they readily flash aflame, because
The tow and torches, also, in themselves
Have many seeds of latent fire. Indeed,
And seest thou not, when near the nightly lamps
Thou bringest a flaxen wick, extinguished
A moment since, it catches fire before
'Thas touched the flame, and in same wise a torch?
And many another object flashes aflame
When at a distance, touched by heat alone,
Before 'tis steeped in veritable fire.
This, then, we must suppose to come to pass
In that spring also.
  Now to other things!
And I'll begin to treat by what decree
Of nature it came to pass that iron can be
By that stone drawn which Greeks the magnet call
After the country's name (its origin
Being in country of Magnesian folk).
This stone men marvel at; and sure it oft
Maketh a chain of rings, depending, lo,
From off itself! Nay, thou mayest see at times
Five or yet more in order dangling down
And swaying in the delicate winds, whilst one
Depends from other, cleaving to under-side,
And ilk one feels the stone's own power and bonds-
So over-masteringly its power flows down.
  In things of this sort, much must be made sure
Ere thou account of the thing itself canst give,
And the approaches roundabout must be;
Wherefore the more do I exact of thee
A mind and ears attent.
  First, from all things
We see soever, evermore must flow,
Must be discharged and strewn about, about,
Bodies that strike the eyes, awaking sight.
From certain things flow odours evermore,
As cold from rivers, heat from sun, and spray
From waves of ocean, eater-out of walls
Along the coasts. Nor ever cease to seep
The varied echoings athrough the air.
Then, too, there comes into the mouth at times
The wet of a salt taste, when by the sea
We roam about; and so, whene'er we watch
The wormwood being mixed, its bitter stings.
To such degree from all things is each thing
Borne streamingly along, and sent about
To every region round; and nature grants
Nor rest nor respite of the onward flow,
Since 'tis incessantly we feeling have,
And all the time are suffered to descry
And smell all things at hand, and hear them sound.
  Now will I seek again to bring to mind
How porous a body all things have- a fact
Made manifest in my first canto, too.
For, truly, though to know this doth import
For many things, yet for this very thing
On which straightway I'm going to discourse,
'Tis needful most of all to make it sure
That naught's at hand but body mixed with void.
A first ensample: in grottos, rocks o'erhead
Sweat moisture and distil the oozy drops;
Likewise, from all our body seeps the sweat;
There grows the beard, and along our members all
And along our frame the hairs. Through all our veins
Disseminates the foods, and gives increase
And aliment down to the extreme parts,
Even to the tiniest finger-nails. Likewise,
Through solid bronze the cold and fiery heat
We feel to pass; likewise, we feel them pass
Through gold, through silver, when we clasp in hand
The brimming goblets. And, again, there flit
Voices through houses' hedging walls of stone;
Odour seeps through, and cold, and heat of fire
That's wont to penetrate even strength of iron.
Again, where corselet of the sky girds round
  .  .  .  .  .  .
And at same time, some Influence of bane,
When from Beyond 'thas stolen into [our world].
And tempests, gathering from the earth and sky,
Back to the sky and earth absorbed retire-
With reason, since there's naught that's fashioned not
With body porous.
  Furthermore, not all
The particles which be from things thrown off
Are furnished with same qualities for sense,
Nor be for all things equally adapt.
A first ensample: the sun doth bake and parch
The earth; but ice he thaws, and with his beams
Compels the lofty snows, up-reared white
Upon the lofty hills, to waste away;
Then, wax, if set beneath the heat of him,
Melts to a liquid. And the fire, likewise,
Will melt the copper and will fuse the gold,
But hides and flesh it shrivels up and shrinks.
The water hardens the iron just off the fire,
But hides and flesh (made hard by heat) it softens.
The oleaster-tree as much delights
The bearded she-goats, verily as though
'Twere nectar-steeped and shed ambrosia;
Than which is naught that burgeons into leaf
More bitter food for man. A hog draws back
For marjoram oil, and every unguent fears
Fierce poison these unto the bristled hogs,
Yet unto us from time to time they seem,
As 'twere, to give new life. But, contrariwise,
Though unto us the mire be filth most foul,
To hogs that mire doth so delightsome seem
That they with wallowing from belly to back
Are never cloyed.
  A point remains, besides,
Which best it seems to tell of, ere I go
To telling of the fact at hand itself.
Since to the varied things assigned be
The many pores, those pores must be diverse
In nature one from other, and each have
Its very shape, its own direction fixed.
And so, indeed, in breathing creatures be
The several senses, of which each takes in
Unto itself, in its own fashion ever,
Its own peculiar object. For we mark
How sounds do into one place penetrate,
Into another flavours of all juice,
And savour of smell into a third. Moreover,
One sort through rocks we see to seep, and, lo,
One sort to pass through wood, another still
Through gold, and others to go out and off
Through silver and through glass. For we do see
Through some pores form-and-look of things to flow,
Through others heat to go, and some things still
To speedier pass than others through same pores.
Of verity, the nature of these same paths,
Varying in many modes (as aforesaid)
Because of unlike nature and warp and woof
Of cosmic things, constrains it so to be.
  Wherefore, since all these matters now have been
Established and settled well for us
As premises prepared, for what remains
'Twill not be hard to render clear account
By means of these, and the whole cause reveal
Whereby the magnet lures the strength of iron.
First, stream there must from off the lode-stone seeds
Innumerable, a very tide, which smites
By blows that air asunder lying betwixt
The stone and iron. And when is emptied out
This space, and a large place between the two
Is made a void, forthwith the primal germs
Of iron, headlong slipping, fall conjoined
Into the vacuum, and the ring itself
By reason thereof doth follow after and go
Thuswise with all its body. And naught there is
That of its own primordial elements
More thoroughly knit or tighter linked coheres
Than nature and cold roughness of stout iron.
Wherefore, 'tis less a marvel what I said,
That from such elements no bodies can
From out the iron collect in larger throng
And be into the vacuum borne along,
Without the ring itself do follow after.
And this it does, and followeth on until
'Thath reached the stone itself and cleaved to it
By links invisible. Moreover, likewise,
The motion's assisted by a thing of aid
(Whereby the process easier becomes),-
Namely, by this: as soon as rarer grows
That air in front of the ring, and space between
Is emptied more and made a void, forthwith
It happens all the air that lies behind
Conveys it onward, pushing from the rear.
For ever doth the circumambient air
Drub things unmoved, but here it pushes forth
The iron, because upon one side the space
Lies void and thus receives the iron in.
This air, whereof I am reminding thee,
Winding athrough the iron's abundant pores
So subtly into the tiny parts thereof,
Shoves it and pushes, as wind the ship and sails.
The same doth happen in all directions forth:
From whatso side a space is made a void,
Whether from crosswise or above, forthwith
The neighbour particles are borne along
Into the vacuum; for of verity,
They're set a-going by poundings from elsewhere,
Nor by themselves of own accord can they
Rise upwards into the air. Again, all things
Must in their framework hold some air, because
They are of framework porous, and the air
Encompasses and borders on all things.
Thus, then, this air in iron so deeply stored
Is tossed evermore in vexed motion,
And therefore drubs upon the ring sans doubt
And shakes it up inside….
  .  .  .  .  .  .
In sooth, that ring is thither borne along
To where 'thas once plunged headlong- thither, lo,
Unto the void whereto it took its start.
  It happens, too, at times that nature of iron
Shrinks from this stone away, accustomed
By turns to flee and follow. Yea, I've seen
Those Samothracian iron rings leap up,
And iron filings in the brazen bowls
Seethe furiously, when underneath was set
The magnet stone. So strongly iron seems
To crave to flee that rock. Such discord great
Is gendered by the interposed brass,
Because, forsooth, when first the tide of brass
Hath seized upon and held possession of
The iron's open passage-ways, thereafter
Cometh the tide of the stone, and in that iron
Findeth all spaces full, nor now hath holes
To swim through, as before. 'Tis thus constrained
With its own current 'gainst the iron's fabric
To dash and beat; by means whereof it spues
Forth from itself- and through the brass stirs up-
The things which otherwise without the brass
It sucks into itself. In these affairs
Marvel thou not that from this stone the tide
Prevails not likewise other things to move
With its own blows: for some stand firm by weight,
As gold; and some cannot be moved forever,
Because so porous in their framework they
That there the tide streams through without a break,
Of which sort stuff of wood is seen to be.
Therefore, when iron (which lies between the two)
Hath taken in some atoms of the brass,
Then do the streams of that Magnesian rock
Move iron by their smitings.
  Yet these things
Are not so alien from others, that I
Of this same sort am ill prepared to name
Ensamples still of things exclusively
To one another adapt. Thou seest, first,
How lime alone cementeth stones: how wood
Only by glue-of-bull with wood is joined-
So firmly too that oftener the boards
Crack open along the weakness of the grain
Ere ever those taurine bonds will lax their hold.
The vine-born juices with the water-springs
Are bold to mix, though not the heavy pitch
With the light oil-of-olive. And purple dye
Of shell-fish so uniteth with the wool's
Body alone that it cannot be ta'en
Away forever- nay, though thou gavest toil
To restore the same with the Neptunian flood,
Nay, though all ocean willed to wash it out
With all its waves. Again, gold unto gold
Doth not one substance bind, and only one?
And is not brass by tin joined unto brass?
And other ensamples how many might one find!
What then? Nor is there unto thee a need
Of such long ways and roundabout, nor boots it
For me much toil on this to spend. More fit
It is in few words briefly to embrace
Things many: things whose textures fall together
So mutually adapt, that cavities
To solids correspond, these cavities
Of this thing to the solid parts of that,
And those of that to solid parts of this-
Such joinings are the best. Again, some things
Can be the one with other coupled and held,
Linked by hooks and eyes, as 'twere; and this
Seems more the fact with iron and this stone.
Now, of diseases what the law, and whence
The Influence of bane upgathering can
Upon the race of man and herds of cattle
Kindle a devastation fraught with death,
I will unfold. And, first, I've taught above
That seeds there be of many things to us
Life-giving, and that, contrariwise, there must
Fly many round bringing disease and death.
When these have, haply, chanced to collect
And to derange the atmosphere of earth,
The air becometh baneful. And, lo, all
That Influence of bane, that pestilence,
Or from Beyond down through our atmosphere,
Like clouds and mists, descends, or else collects
From earth herself and rises, when, a-soak
And beat by rains unseasonable and suns,
Our earth hath then contracted stench and rot.
Seest thou not, also, that whoso arrive
In region far from fatherland and home
Are by the strangeness of the clime and waters
Distempered?- since conditions vary much.
For in what else may we suppose the clime
Among the Britons to differ from Aegypt's own
(Where totters awry the axis of the world),
Or in what else to differ Pontic clime
From Gades' and from climes adown the south,
On to black generations of strong men
With sun-baked skins? Even as we thus do see
Four climes diverse under the four main-winds
And under the four main-regions of the sky,
So, too, are seen the colour and face of men
Vastly to disagree, and fixed diseases
To seize the generations, kind by kind:
There is the elephant-disease which down
In midmost Aegypt, hard by streams of Nile,
Engendered is- and never otherwhere.
In Attica the feet are oft attacked,
And in Achaean lands the eyes. And so
The divers spots to divers parts and limbs
Are noxious; 'tis a variable air
That causes this. Thus when an atmosphere,
Alien by chance to us, begins to heave,
And noxious airs begin to crawl along,
They creep and wind like unto mist and cloud,
Slowly, and everything upon their way
They disarrange and force to change its state.
It happens, too, that when they've come at last
Into this atmosphere of ours, they taint
And make it like themselves and alien.
Therefore, asudden this devastation strange,
This pestilence, upon the waters falls,
Or settles on the very crops of grain
Or other meat of men and feed of flocks.
Or it remains a subtle force, suspense
In the atmosphere itself; and when therefrom
We draw our inhalations of mixed air,
Into our body equally its bane
Also we must suck in. In manner like,
Oft comes the pestilence upon the kine,
And sickness, too, upon the sluggish sheep.
Nor aught it matters whether journey we
To regions adverse to ourselves and change
The atmospheric cloak, or whether nature
Herself import a tainted atmosphere
To us or something strange to our own use
Which can attack us soon as ever it come.
