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 t
