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.
