Part 15

For in a two-fold manner is that wind Enkindled all: it trembles into heat Both by its own velocity and by Repeated touch of fire. Thereafter, when The energy of wind is heated through And the fierce impulse of the fire hath sped Deeply within, O then the thunderbolt, Now ripened, so to say, doth suddenly Splinter the cloud, and the aroused flash Leaps onward, lumining with forky light All places round. And followeth anon A clap so heavy that the skiey vaults, As if asunder burst, seem from on high To engulf the earth. Then fearfully a quake Pervades the lands, and 'long the lofty skies Run the far rumblings. For at such a time Nigh the whole tempest quakes, shook through and through, And roused are the roarings,--from which shock Comes such resounding and abounding rain, That all the murky ether seems to turn Now into rain, and, as it tumbles down, To summon the fields back to primeval floods: So big the rains that be sent down on men By burst of cloud and by the hurricane, What time the thunder-clap, from burning bolt That cracks the cloud, flies forth along. At times The force of wind, excited from without, Smiteth into a cloud already hot With a ripe thunderbolt. And when that wind Hath splintered that cloud, then down there cleaves forthwith Yon fiery coil of flame which still we call, Even with our fathers' word, a thunderbolt.

The same thing haps toward every other side Whither that force hath swept. It happens, too, That sometimes force of wind, though hurtled forth Without all fire, yet in its voyage through s.p.a.ce Igniteth, whilst it comes along, along,-- Losing some larger bodies which cannot Pa.s.s, like the others, through the bulks of air,-- And, sc.r.a.ping together out of air itself Some smaller bodies, carries them along, And these, commingling, by their flight make fire: Much in the manner as oft a leaden ball Grows hot upon its aery course, the while It loseth many bodies of stark cold And taketh into itself along the air New particles of fire. It happens, too, That force of blow itself arouses fire, When force of wind, a-cold and hurtled forth Without all fire, hath strook somewhere amain-- No marvel, because, when with terrific stroke 'Thas smitten, the elements of fiery-stuff Can stream together from out the very wind And, simultaneously, from out that thing Which then and there receives the stroke: as flies The fire when with the steel we hack the stone; Nor yet, because the force of steel's a-cold, Rush the less speedily together there Under the stroke its seeds of radiance hot.

And therefore, thuswise must an object too Be kindled by a thunderbolt, if haply 'Thas been adapt and suited to the flames.

Yet force of wind must not be rashly deemed As altogether and entirely cold-- That force which is discharged from on high With such stupendous power; but if 'tis not Upon its course already kindled with fire, It yet arriveth warmed and mixed with heat.

And, now, the speed and stroke of thunderbolt Is so tremendous, and with glide so swift Those thunderbolts rush on and down, because Their roused force itself collects itself First always in the clouds, and then prepares For the huge effort of their going-forth; Next, when the cloud no longer can retain The increment of their fierce impetus, Their force is pressed out, and therefore flies With impetus so wondrous, like to shots Hurled from the powerful Roman catapults.

Note, too, this force consists of elements Both small and smooth, nor is there aught that can With ease resist such nature. For it darts Between and enters through the pores of things; And so it never falters in delay Despite innumerable collisions, but Flies shooting onward with a swift elan.

Next, since by nature always every weight Bears downward, doubled is the swiftness then And that elan is still more wild and dread, When, verily, to weight are added blows, So that more madly and more fiercely then The thunderbolt shakes into shivers all That blocks its path, following on its way.

Then, too, because it comes along, along With one continuing elan, it must Take on velocity anew, anew, Which still increases as it goes, and ever Augments the bolt's vast powers and to the blow Gives larger vigour; for it forces all, All of the thunder's seeds of fire, to sweep In a straight line unto one place, as 'twere,-- Casting them one by other, as they roll, Into that onward course. Again, perchance, In coming along, it pulls from out the air Some certain bodies, which by their own blows Enkindle its velocity. And, lo, It comes through objects leaving them unharmed, It goes through many things and leaves them whole, Because the liquid fire flieth along Athrough their pores. And much it does transfix, When these primordial atoms of the bolt Have fallen upon the atoms of these things Precisely where the intertwined atoms Are held together. And, further, easily Bra.s.s it unbinds and quickly fuseth gold, Because its force is so minutely made Of tiny parts and elements so smooth That easily they wind their way within, And, when once in, quickly unbind all knots And loosen all the bonds of union there.

And most in autumn is shaken the house of heaven, The house so studded with the glittering stars, And the whole earth around--most too in spring When flowery times unfold themselves: for, lo, In the cold season is there lack of fire, And winds are scanty in the hot, and clouds Have not so dense a bulk. But when, indeed, The seasons of heaven are betwixt these twain, The divers causes of the thunderbolt Then all concur; for then both cold and heat Are mixed in the cross-seas of the year, So that a discord rises among things And air in vast tumultuosity Billows, infuriate with the fires and winds-- Of which the both are needed by the cloud For fabrication of the thunderbolt.

For the first part of heat and last of cold Is the time of spring; wherefore must things unlike Do battle one with other, and, when mixed, Tumultuously rage. And when rolls round The latest heat mixed with the earliest chill-- The time which bears the name of autumn--then Likewise fierce cold-spells wrestle with fierce heats.

On this account these seasons of the year Are nominated "cross-seas."--And no marvel If in those times the thunderbolts prevail And storms are roused turbulent in heaven, Since then both sides in dubious warfare rage Tumultuously, the one with flames, the other With winds and with waters mixed with winds.

This, this it is, O Memmius, to see through The very nature of fire-fraught thunderbolt; O this it is to mark by what blind force It maketh each effect, and not, O not To unwind Etrurian scrolls oracular, Inquiring tokens of occult will of G.o.ds, Even as to whence the flying flame hath come, Or to which half of heaven it turns, or how Through walled places it hath wound its way, Or, after proving its dominion there, How it hath speeded forth from thence amain, Or what the thunderstroke portends of ill From out high heaven. But if Jupiter And other G.o.ds shake those refulgent vaults With dread reverberations and hurl fire Whither it pleases each, why smite they not Mortals of reckless and revolting crimes, That such may pant from a transpierced breast Forth flames of the red levin--unto men A drastic lesson?--why is rather he-- O he self-conscious of no foul offence-- Involved in flames, though innocent, and clasped Up-caught in skiey whirlwind and in fire?

Nay, why, then, aim they at eternal wastes, And spend themselves in vain?--perchance, even so To exercise their arms and strengthen shoulders?

Why suffer they the Father's javelin To be so blunted on the earth? And why Doth he himself allow it, nor spare the same Even for his enemies? O why most oft Aims he at lofty places? Why behold we Marks of his lightnings most on mountain tops?

Then for what reason shoots he at the sea?-- What sacrilege have waves and bulk of brine And floating fields of foam been guilty of?

Besides, if 'tis his will that we beware Against the lightning-stroke, why feareth he To grant us power for to behold the shot?

And, contrariwise, if wills he to o'erwhelm us, Quite off our guard, with fire, why thunders he Off in yon quarter, so that we may shun?

Why rouseth he beforehand darkling air And the far din and rumblings? And O how Canst thou believe he shoots at one same time Into diverse directions? Or darest thou Contend that never hath it come to pa.s.s That divers strokes have happened at one time?

But oft and often hath it come to pa.s.s, And often still it must, that, even as showers And rains o'er many regions fall, so too Dart many thunderbolts at one same time.

Again, why never hurtles Jupiter A bolt upon the lands nor pours abroad Clap upon clap, when skies are cloudless all?

Or, say, doth he, so soon as ever the clouds Have come thereunder, then into the same Descend in person, that from thence he may Near-by decide upon the stroke of shaft?

And, lastly, why, with devastating bolt Shakes he asunder holy shrines of G.o.ds And his own thrones of splendour, and to-breaks The well-wrought idols of divinities, And robs of glory his own images By wound of violence?

But to return apace, Easy it is from these same facts to know In just what wise those things (which from their sort The Greeks have named "bellows") do come down, Discharged from on high, upon the seas.

For it haps that sometimes from the sky descends Upon the seas a column, as if pushed, Round which the surges seethe, tremendously Aroused by puffing gusts; and whatso'er Of ships are caught within that tumult then Come into extreme peril, dashed along.

This haps when sometimes wind's aroused force Can't burst the cloud it tries to, but down-weighs That cloud, until 'tis like a column from sky Upon the seas pushed downward--gradually, As if a Somewhat from on high were shoved By fist and nether thrust of arm, and lengthened Far to the waves. And when the force of wind Hath rived this cloud, from out the cloud it rushes Down on the seas, and starts among the waves A wondrous seething, for the eddying whirl Descends and downward draws along with it That cloud of ductile body. And soon as ever 'Thas shoved unto the levels of the main That laden cloud, the whirl suddenly then Plunges its whole self into the waters there And rouses all the sea with monstrous roar, Constraining it to seethe. It happens too That very vortex of the wind involves Itself in clouds, sc.r.a.ping from out the air The seeds of cloud, and counterfeits, as 'twere, The "bellows" pushed from heaven. And when this shape Hath dropped upon the lands and burst apart, It belches forth immeasurable might Of whirlwind and of blast. Yet since 'tis formed At most but rarely, and on land the hills Must block its way, 'tis seen more oft out there On the broad prospect of the level main Along the free horizons.

Into being The clouds condense, when in this upper s.p.a.ce Of the high heaven have gathered suddenly, As round they flew, unnumbered particles-- World's rougher ones, which can, though interlinked With scanty couplings, yet be fastened firm, The one on other caught. These particles First cause small clouds to form; and, thereupon, These catch the one on other and swarm in a flock And grow by their conjoining, and by winds Are borne along, along, until collects The tempest fury. Happens, too, the nearer The mountain summits neighbour to the sky, The more unceasingly their far crags smoke With the thick darkness of swart cloud, because When first the mists do form, ere ever the eyes Can there behold them (tenuous as they be), The carrier-winds will drive them up and on Unto the topmost summits of the mountain; And then at last it happens, when they be In vaster throng upgathered, that they can By this very condensation lie revealed, And that at same time they are seen to surge From very vertex of the mountain up Into far ether. For very fact and feeling, As we up-climb high mountains, proveth clear That windy are those upward regions free.

Besides, the clothes hung-out along the sh.o.r.e, When in they take the clinging moisture, prove That nature lifts from over all the sea Unnumbered particles. Whereby the more 'Tis manifest that many particles Even from the salt upheavings of the main Can rise together to augment the bulk Of ma.s.sed clouds. For moistures in these twain Are near akin. Besides, from out all rivers, As well as from the land itself, we see Up-rising mists and steam, which like a breath Are forced out from them and borne aloft, To curtain heaven with their murk, and make, By slow foregathering, the skiey clouds.

For, in addition, lo, the heat on high Of constellated ether burdens down Upon them, and by sort of condensation Weaveth beneath the azure firmament The reek of darkling cloud. It happens, too, That hither to the skies from the Beyond Do come those particles which make the clouds And flying thunderheads. For I have taught That this their number is innumerable And infinite the sum of the Abyss, And I have shown with what stupendous speed Those bodies fly and how they're wont to pa.s.s Amain through incommunicable s.p.a.ce.

Therefore, 'tis not exceeding strange, if oft In little time tempest and darkness cover With bulking thunderheads hanging on high The oceans and the lands, since everywhere Through all the narrow tubes of yonder ether, Yea, so to speak, through all the breathing-holes Of the great upper-world encompa.s.sing, There be for the primordial elements Exits and entrances.

Now come, and how The rainy moisture thickens into being In the lofty clouds, and how upon the lands 'Tis then discharged in down-pour of large showers, I will unfold. And first triumphantly Will I persuade thee that up-rise together, With clouds themselves, full many seeds of water From out all things, and that they both increase-- Both clouds and water which is in the clouds-- In like proportion, as our frames increase In like proportion with our blood, as well As sweat or any moisture in our members.

Besides, the clouds take in from time to time Much moisture risen from the broad marine,-- Whilst the winds bear them o'er the mighty sea, Like hanging fleeces of white wool. Thuswise, Even from all rivers is there lifted up Moisture into the clouds. And when therein The seeds of water so many in many ways Have come together, augmented from all sides, The close-jammed clouds then struggle to discharge Their rain-storms for a two-fold reason: lo, The wind's force crowds them, and the very excess Of storm-clouds (ma.s.sed in a vaster throng) Giveth an urge and pressure from above And makes the rains out-pour. Besides when, too, The clouds are winnowed by the winds, or scattered Smitten on top by heat of sun, they send Their rainy moisture, and distil their drops, Even as the wax, by fiery warmth on top, Wasteth and liquefies abundantly.

But comes the violence of the bigger rains When violently the clouds are weighted down Both by their c.u.mulated ma.s.s and by The onset of the wind. And rains are wont To endure awhile and to abide for long, When many seeds of waters are aroused, And clouds on clouds and racks on racks outstream In piled layers and are borne along From every quarter, and when all the earth Smoking exhales her moisture. At such a time When sun with beams amid the tempest-murk Hath shone against the showers of black rains, Then in the swart clouds there emerges bright The radiance of the bow.

And as to things Not mentioned here which of themselves do grow Or of themselves are gendered, and all things Which in the clouds condense to being--all, Snow and the winds, hail and the h.o.a.r-frosts chill, And freezing, mighty force--of lakes and pools The mighty hardener, and mighty check Which in the winter curbeth everywhere The rivers as they go--'tis easy still, Soon to discover and with mind to see How they all happen, whereby gendered, When once thou well hast understood just what Functions have been vouchsafed from of old Unto the procreant atoms of the world.

Now come, and what the law of earthquakes is Hearken, and first of all take care to know That the under-earth, like to the earth around us, Is full of windy caverns all about; And many a pool and many a grim abyss She bears within her bosom, ay, and cliffs And jagged scarps; and many a river, hid Beneath her chine, rolls rapidly along Its billows and plunging boulders. For clear fact Requires that earth must be in every part Alike in const.i.tution. Therefore, earth, With these things underneath affixed and set, Trembleth above, jarred by big down-tumblings, When time hath undermined the huge caves, The subterranean. Yea, whole mountains fall, And instantly from spot of that big jar There quiver the tremors far and wide abroad.

And with good reason: since houses on the street Begin to quake throughout, when jarred by a cart Of no large weight; and, too, the furniture Within the house up-bounds, when a paving-block Gives either iron rim of the wheels a jolt.

It happens, too, when some prodigious bulk Of age-worn soil is rolled from mountain slopes Into tremendous pools of water dark, That the reeling land itself is rocked about By the water's undulations; as a basin Sometimes won't come to rest until the fluid Within it ceases to be rocked about In random undulations.

And besides, When subterranean winds, up-gathered there In the hollow deeps, bulk forward from one spot, And press with the big urge of mighty powers Against the lofty grottos, then the earth Bulks to that quarter whither push amain The headlong winds. Then all the builded houses Above ground--and the more, the higher up-reared Unto the sky--lean ominously, careening Into the same direction; and the beams, Wrenched forward, over-hang, ready to go.

Yet dread men to believe that there awaits The nature of the mighty world a time Of doom and cataclysm, albeit they see So great a bulk of lands to bulge and break!

And lest the winds blew back again, no force Could rein things in nor hold from sure career On to disaster. But now because those winds Blow back and forth in alternation strong, And, so to say, rallying charge again, And then repulsed retreat, on this account Earth oftener threatens than she brings to pa.s.s Collapses dire. For to one side she leans, Then back she sways; and after tottering Forward, recovers then her seats of poise.

Thus, this is why whole houses rock, the roofs More than the middle stories, middle more Than lowest, and the lowest least of all.

Arises, too, this same great earth-quaking, When wind and some prodigious force of air, Collected from without or down within The old telluric deeps, have hurled themselves Amain into those caverns sub-terrene, And there at first tumultuously chafe Among the vasty grottos, borne about In mad rotations, till their lashed force Aroused out-bursts abroad, and then and there, Riving the deep earth, makes a mighty chasm-- What once in Syrian Sidon did befall, And once in Peloponnesian Aegium, Twain cities which such out-break of wild air And earth's convulsion, following hard upon, O'erthrew of old. And many a walled town, Besides, hath fall'n by such omnipotent Convulsions on the land, and in the sea Engulfed hath sunken many a city down With all its populace. But if, indeed, They burst not forth, yet is the very rush Of the wild air and fury-force of wind Then dissipated, like an ague-fit, Through the innumerable pores of earth, To set her all a-shake--even as a chill, When it hath gone into our marrow-bones, Sets us convulsively, despite ourselves, A-shivering and a-shaking. Therefore, men With two-fold terror bustle in alarm Through cities to and fro: they fear the roofs Above the head; and underfoot they dread The caverns, lest the nature of the earth Suddenly rend them open, and she gape, Herself asunder, with tremendous maw, And, all confounded, seek to chock it full With her own ruins. Let men, then, go on Feigning at will that heaven and earth shall be Inviolable, entrusted evermore To an eternal weal: and yet at times The very force of danger here at hand Prods them on some side with this goad of fear-- This among others--that the earth, withdrawn Abruptly from under their feet, be hurried down, Down into the abyss, and the Sum-of-Things Be following after, utterly fordone, Till be but wrack and wreckage of a world.

EXTRAORDINARY AND PARADOXICAL TELLURIC PHENOMENA

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 sh.o.r.es, 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 pa.s.sing 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 cla.s.s, 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 pa.s.s 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, r.e.t.a.r.d, 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 ma.s.sed 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 c.u.mae, 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-G.o.ds.

Lo, all these wonders work by natural law, And from what causes they are brought to pa.s.s 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-G.o.ds draw down Souls to dark sh.o.r.es 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, a.s.sails 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!
