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 through houses' hedging walls of stone;
Odour seeps through; and cold; and heat of fire
That's wont to penetrate even strength of iron。
Again; where corselet of the sky girds round
       。     。     。     。     。     。
And at same time; some Influence of bane;
When from Beyond 'thas stolen into 'our world'。
And tempests; gathering from the earth and sky;
Back to the sky and earth absorbed retire…
With reason; since there's naught that's fashioned not
With body porous。
                   Furthermore; not all
The particles which be from things thrown off
Are furnished with same qualities for sense;
Nor be for all things equally adapt。
A first ensample: the sun doth bake and parch
The earth; but ice he thaws; and with his beams
Compels the lofty snows; up…reared white
Upon the lofty hills; to waste away;
Then; wax; if set beneath the heat of him;
Melts to a liquid。 And the fire; likewise;
Will melt the copper and will fuse the gold;
But hides and flesh it shrivels up and shrinks。
The water hardens the iron just off the fire;
But hides and flesh (made hard by heat) it softens。
The oleaster…tree as much delights
The bearded she…goats; verily as though
'Twere nectar…steeped and shed ambrosia;
Than which is naught that burgeons into leaf
More bitter food for man。 A hog draws back
For marjoram oil; and every unguent fears
Fierce poison these unto the bristled hogs;
Yet unto us from time to time they seem;
As 'twere; to give new life。 But; contrariwise;
Though unto us the mire be filth most foul;
To hogs that mire doth so delightsome seem
That they with wallowing from belly to back
Are never cloyed。
                   A point remains; besides;
Which best it seems to tell of; ere I go
To telling of the fact at hand itself。
Since to the varied things assigned be
The many pores; those pores must be diverse
In nature one from other; and each have
Its very shape; its own direction fixed。
And so; indeed; in breathing creatures be
The several senses; of which each takes in
Unto itself; in its own fashion ever;
Its own peculiar object。 For we mark
How sounds do into one place penetrate;
Into another flavours of all juice;
And savour of smell into a third。 Moreover;
One sort through rocks we see to seep; and; lo;
One sort to pass through wood; another still
Through gold; and others to go out and off
Through silver and through glass。 For we do see
Through some pores form…and…look of things to flow;
Through others heat to go; and some things still
To speedier pass than others through same pores。
Of verity; the nature of these same paths;
Varying in many modes (as aforesaid)
Because of unlike nature and warp and woof
Of cosmic things; constrains it so to be。
  Wherefore; since all these matters now have been
Established and settled well for us
As premises prepared; for what remains
'Twill not be hard to render clear account
By means of these; and the whole cause reveal
Whereby the magnet lures the strength of iron。
First; stream there must from off the lode…stone seeds
Innumerable; a very tide; which smites
By blows that air asunder lying betwixt
The stone and iron。 And when is emptied out
This space; and a large place between the two
Is made a void; forthwith the primal germs
Of iron; headlong slipping; fall conjoined
Into the vacuum; and the ring itself
By reason thereof doth follow after and go
Thuswise with all its body。 And naught there is
That of its own primordial elements
More thoroughly knit or tighter linked coheres
Than nature and cold roughness of stout iron。
Wherefore; 'tis less a marvel what I said;
That from such elements no bodies can
From out the iron collect in larger throng
And be into the vacuum borne along;
Without the ring itself do follow after。
And this it does; and followeth on until
'Thath reached the stone itself and cleaved to it
By links invisible。 Moreover; likewise;
The motion's assisted by a thing of aid
(Whereby the process easier becomes);…
Namely; by this: as soon as rarer grows
That air in front of the ring; and space between
Is emptied more and made a void; forthwith
It happens all the air that lies behind
Conveys it onward; pushing from the rear。
For ever doth the circumambient air
Drub things unmoved; but here it pushes forth
The iron; because upon one side the space
Lies void and thus receives the iron in。
This air; whereof I am reminding thee;
Winding athrough the iron's abundant pores
So subtly into the tiny parts thereof;
Shoves it and pushes; as wind the ship and sails。
The same doth happen in all directions forth:
From whatso side a space is made a void;
Whether from crosswise or above; forthwith
The neighbour particles are borne along
Into the vacuum; for of verity;
They're set a…going by poundings from elsewhere;
Nor by themselves of own accord can they
Rise upwards into the air。 Again; all things
Must in their framework hold some air; because
They are of framework porous; and the air
Encompasses and borders on all things。
Thus; then; this air in iron so deeply stored
Is tossed evermore in vexed motion;
And therefore drubs upon the ring sans doubt
And shakes it up inside。。。。
       。     。     。     。     。     。
In sooth; that ring is thither borne along
To where 'thas once plunged headlong… thither; lo;
Unto the void whereto it took its start。
  It happens; too; at times that nature of iron
Shrinks from this stone away; accustomed
By turns to flee and follow。 Yea; I've seen
Those Samothracian iron rings leap up;
And iron filings in the brazen bowls
Seethe furiously; when underneath was set
The magnet stone。 So strongly iron seems
To crave to flee that rock。 Such discord great
Is gendered by the interposed brass;
Because; forsooth; when first the tide of brass
Hath seized upon and held possession of
The iron's open passage…ways; thereafter
Cometh the tide of the stone; and in that iron
Findeth all spaces full; nor now hath holes
To swim through; as before。 'Tis thus constrained
With its own current 'gainst the iron's fabric
To dash and beat; b
