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.
