Book VI, Part 4

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very force of danger here at hand Prods them on some side with this goad of fear- This among others- that the earth, withdrawn Abruptly from under their feet, be hurried down, Down into the abyss, and the Sum-of-Things Be following after, utterly fordone, Till be but wrack and wreckage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 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 north winds 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 north winds 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 there under 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.
