De Rerum Natura

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-
