For this reason when night has buried the earth in its dewy shadows, the earth at once becomes quite cold and contracts: in this way just as if it were squeezed by the hand it forces out into the fountain whatever seeds of fire it has; and these make the water hot to the touch and taste.
Next when the sun has risen and with his rays has loosened the earth and has rarefied it as his heat waxes stronger, the first-beginnings of fire return back to their ancient seats and all the heat of the water withdraws into the earth: for this reason the fountain becomes cold in the daylight.
Again the liquid of water is played upon by the sun’s rays and in the daytime is rarefied by his throbbing heat; and therefore it gives up whatever seeds of fire it has; just as it often parts with the frost which it holds in itself, and thaws the ice and loosens its bonds.
[879] There is also a cold fountain of such a nature that tow, often when held over it, imbibes fire forthwith and emits flame; a pine torch in like manner is lighted and shines among the waters, in whatever direction it swims under the impulse of the winds.
Because sure enough there are in the water very many seeds of heat, and from the earth itself at the bottom must rise up bodies of fire throughout the whole fountain and at the same time pass abroad in exhalations and go forth into the air, not in such numbers however that the fountain can become hot, for these reasons a force compels those seeds to burst out through the water and disperse abroad and to unite when they have mounted up.
In the sea at Aradus is a fountain of this kind, which wells up with fresh water and keeps off the salt waters all round it; and in many other quarters the sea affords a seasonable help in need to thirsting sailors, vomiting forth fresh waters amid the salt.
In this way then those seeds may burst forth through that fountain and well out; and when they are met together in the tow or cohere in the body of the pine-torch, they at once readily take fire, because the tow and pinewood contain in them likewise many seeds of latent fire.
See you not too that, when you bring a newly extinguished wick near night-lamps it catches light before it has touched the flame; and the same with the pinewood? And many things beside catch fire at some distance touched merely by the heat, before the fire in actual contact infects them.
This therefore you must suppose to take place in that fountain as well.
Next in order I will proceed to discuss by what law of nature it comes to pass that iron can be attracted by that stone which the Greeks call the Magnet from the name of its native place, because it has its origin within the bounds of the country of the Magnesians.
This stone men wonder at; as it often produces a chain of rings hanging down from it.
Thus you may see sometimes five and more suspended in succession and tossing about in the light airs, one always hanging down from one and attached to its lower side, and each in turn one from the other experiencing the binding power of the stone: with such a continued current its force flies through all.
In things of this kind many points must be established before you can assign the true law of the thing in question, and it must be approached by a very circuitous road; [920] wherefore all the more I call for an attentive ear and mind.
In the first place from all things whatsoever which we see there must incessantly stream and be discharged and scattered abroad such bodies as strike the eyes and provoke vision.
Smells too incessantly stream from certain things; as does cold from rivers, heat from the sun, spray from the waves of the sea that eats into walls near the shore.
Various sounds too cease not to stream through the air.
Then a moist salt flavor often comes into the mouth, when we are moving about beside the sea; and when we look on at the mixing of a decoction of wormwood, its bitterness affects us.
In such a constant stream from all things the several qualities of things are carried and are transmitted in all directions round, and no delay, no respite in the flow is ever granted, since we constantly have feeling, and may at anytime see, smell and hear the sound of anything.
And now I will state once again how rare a body all things have: a question made clear in the first part of my poem also: although the knowledge of this is of importance in regard to many things, above all in regard to this very question which I am coming to discuss, at the very outset it is necessary to establish that nothing comes under sense save body mixed with void.
For instance in caves rocks overhead sweat with moisture and trickle down in oozing drops.
Sweat too oozes out from our whole body; the beard grows, and hairs over all our limbs and frame.
Food is distributed through all the veins, gives increase and nourishment to the very extremities and nails.
We feel too cold and heat pass through brass, we feel them pass through gold and silver, when we hold full cups.
Again voices fly through the stone partitions of houses; smell passes through and cold, and the heat of fire which is wont ay to pierce even the strength of iron, where the Gaulish cuirass girds the body round.
And when a storm has gathered in earth and heaven, and when along with it the influence of disease makes its way in from without, they both withdraw respectively to heaven and earth and there work their wills, since there is nothing at all that is not of a rare texture of, body.
Furthermore all bodies whatever which are discharged from things are not qualified to excite the same sensations nor are adapted for all things alike.
The sun for instance bakes and dries up the earth, but thaws ice, and forces the snows piled up high on the high hills to melt away beneath his rays; [964] wax again turns to liquid when placed within reach of his heat,
Fire also melts brass and fuses gold, but shrivels up and draws together hides and flesh.
The liquid of water after fire hardens steel, but softens hides and flesh hardened by heat.
The wild olive delights the bearded she-goats as much as if the flavor it yielded were of ambrosia and steeped in nectar; but nothing that puts forth leaf is more bitter to man than this food.
Again a swine eschews marjoram-oil and dreads all perfumes; for they are rank poison to bristly swine, though they are found at times to give us as it were fresh life.
But on the other hand though mire is to us the nastiest filth, it is found to be so welcome to swine that they wallow in it all over with a craving not to be satisfied.
There is still one point left which it seems proper to mention, before I come to speak of the matter in hand.
Since many pores are assigned to various things, they must possess natures differing the one from the other and must have each its own nature, its own direction: thus there are in living creatures various senses, each of which takes into it in its own peculiar way its own special object; for we see that sounds pass into one thing, taste from different flavors into another thing, smells into another.
Again one thing is seen to stream through stones and another thing to pass through woods, another through gold, and another still to go out through silver and brass; for form is seen to stream through this passage, heat through that, and one thing is seen to pass through by the same way more quickly than other things.
The nature of the passages, you are to know, compels it so to be, varying in manifold wise, as we have shown a little above, owing to the unlike nature and textures of things.
Therefore now that these points have all been established and arranged for us as premisses ready to our hand, for what remains, the law will easily be explained out of them, and the whole cause be laid open which attracts the strength of iron.
First of all there must stream from this stone very many seeds or a current if you will which dispels with blows all the air which lies between the stone andiron.
When this space is emptied and much room left void between, forthwith the first-beginnings of iron fall headlong forward into the void in one mass, and in consequence the ring itself follows and then goes on with its whole body.
[1009] And nothing
has its primal elements more intricately entangled or coheres in closer connection than the nature of stubborn iron and its coldness that makes you shiver.
Therefore what I say is the less strange, that from among such elements as these bodies cannot gather in large numbers out of the iron and be carried into the void without the whole ring following.
This it does do, and follows on until it has quite reached the stone and fastened on it with unseen bonds of connection.
The same thing takes place in all directions: on whatever side a void is formed, whether athwart or from above the first bodies next it are at once carried on into the void; for they are set in motion by blows from another source and cannot by their own free act rise up into the air.
Moreover (to render it more feasible, this thing also is helped on by external aid and motion) as soon as the air in front of the ring has been made rarer and the space more empty and void, it follows at once that all the air which lies behind, carries and pushes it on as it were at its back.
For the air which lies around them always beats on things; but at such a time as this it is able to push on the iron, because on one side a space is void and receives the iron into it.
This air of which I am speaking to you makes its way with much subtlety through the frequent pores of the iron to its minute parts and then thrusts and pushes it on, as the wind a ship and its sails.
Again all things must have air in their body, since they are of a rare body and air surrounds and is in contact with all things.
This air therefore which is in the inmost recesses of the iron, is ever stirred in restless motion and therefore beats the ring without a doubt and stirs it within, you know: the ring is carried in the direction in which it has once plunged forward, and into the void part towards which it has made its start.
Sometimes too it happens that the nature of iron is repelled from this stone, being in the habit of flying from and following it in turns.
I have seen Samothracian iron rings even jump up, and at the same time filings of iron rave within brass basins, when this Magnet stone had been placed under: such a strong desire the iron seems to have to fly from the stone.
So great a disturbance is raised by the interposition of the brass, because sure enough when the current of the brass has first seized on and taken possession of the open passages of the iron, the current of the stone comes after and finds all things full in the iron and has no opening to swim through as before.
[1053] It is forced therefore to dash against and beat with its wave the iron texture; by which means it repels from it and sets in motion through the brass that which without the brass it often draws to itself.
And forbear herein to wonder that the current from this stone is not able to set in motion other things as well as iron: some of these stand still by the power of their own weight; for instance gold; and others, because they are of so rare a body that the current flies through them uninterrupted, cannot in any case be set in motion; to which class wood is found to belong.
When therefore the nature of iron lying between the two has received into it certain first bodies of brass, then do the Magnet stones set it in motion with their stream.
And yet these cases are not so much at variance with other things, that I have only a scanty store of similar instances to relate of things mutually fitted one for the other and for nothing else: stones for instance you see are cemented by mortar alone; wood is united with wood so firmly by bulls’ glue only, that the veins of boards often gape in cracks before the binding power of the glue can be brought to loosen its hold.
Vine-born juices venture to mix with streams of water, though heavy pitch and light oil cannot.
Again the purple dye of the shellfish so unites with the body of wool alone, that it cannot in any case be severed, not were you to take pains to undo what is done with Neptune’s wave, not if the whole sea were willed to wash it out with all its waters.
Then too is there not one thing only that fastens gold to gold, and is not brass soldered to brass by tin? And how many other cases of the kind might one find! What then? You have no need whatever of such long circuitous roads, nor is it worth my while to spend so much pains on this, but it is better briefly to comprise many things in few words: things whose textures have such a mutual correspondence, that cavities fit solids, the cavities of the first the solids of the second, the cavities of the second the solids of the first, form the closest union.
Again some things may be fastened together and held in union with hooks and eyes as it were; and this seems rather to be the case with this stone and iron.
[1090] And now I will explain what the law of diseases is and from what causes the force of disease may suddenly gather itself up and bring death-dealing destruction on the race of man and the troops of brute beasts.
And first I have shown above that there are seeds of many things helpful to our life; and on the other hand many must fly about conducing to disease and death.
When these by chance have happened to gather together and have disordered the atmosphere, the air becomes distempered.
And all that force of disease and that pestilence come either from without down through the atmosphere in the shape of clouds and mists, or else do gather themselves up and rise out of the earth, when soaked with wet it has contracted a taint, being beaten upon by unseasonable rains and suns.
See you not too that all who come to a place far away from country and home are affected by the strangeness of climate and water, because there are wide differences in such things?
For what a difference may we suppose between the climate of the Briton and that of Egypt where the pole of heaven slants askew, and again between that in Pontus and that of Gades and so on to the races of men black with sun-baked complexion?
Now as we see these four climates under the four opposite winds and quarters of heaven all differing from each other, so also the complexions and faces of the men are seen to differ widely and diseases varying in kind are found to seize upon the different races.
There is the elephant disease which is generated beside the streams of Nile in the midst of Egypt and nowhere else.
In Attica the feet are attacked and the eyes in Achaean lands.
And so different places are hurtful to different parts and members: the variations of air occasion that.
Therefore when an atmosphere which happens to put itself in motion unsuited to us and a hurtful air beg into advance, they creep slowly on in the shape of mist and cloud and disorder everything in their line of advance and compel all to change; and when they have at length reached our atmosphere, they corrupt it too and make it like to themselves and unsuited to us.
This new destroying power and pestilence therefore all at once either fall upon the waters or else sink deep into the corn-crops or other food of man and provender of beast; or else their force remains suspended within the atmosphere, and when we inhale from it mixed airs, we must absorb at the same time into our body those things as well.
In like manner pestilence often falls on kine also and a distemper too on the silly sheep.
[1132] And it makes no difference whether we travel to places unfavorable to us and change the atmosphere which wraps us round, or whether nature without our choice brings to us a tainted atmosphere or something to the use of which we have not been accustomed, and which is able to attack us on its first arrival.
Such a form of disease and a death-fraught miasm erst within the borders of Cecrops defiled the whole land with dead, and dispeopled the streets, drained the town of burghers.
Rising first and starting from the inmost corners of Egypt, after traversing much air and many floating fields, the plague brooded at last over the whole people of Pandion; and then they were handed over in troops to disease and death.
First of all they would have the head seized with burning heat and both eyes blood-shot with aglare diffused over; the livid throat within would exude blood and the passage of the voice be clogged and choked with ulc
ers, and the mind’s interpreter the tongue drip with gore, quite enfeebled with sufferings, heavy in movement, rough to touch.
Next when the force of disease passing down the throat had filled the breast and had streamed together even into the sad heart of the sufferers, then would all the barriers of life give way.
The breath would pour out at the mouth a noisome stench, even as the stench of rotting carcasses thrown out unburied.
And then the powers of the entire mind, the whole body would sink utterly, now on the very threshold of death.
And a bitter despondency was the constant attendant on insufferable ills and complaining mingled with moaning.
An ever-recurring hiccup often the night and day through, forcing on continual spasms in sinews and limbs, would break men quite, for wearying those forspent before.
And yet in none could you perceive the skin on the surface of the body burn with any great heat, but the body would rather offer to the hand a lukewarm sensation and at the same time be red all over with ulcers burnt into it so to speak, like unto the holy fire as it spreads over the frame.
The inward parts of the men however would burn to the very bones, a flame would bum within the stomach as within furnaces.
Nothing was light and thin enough to apply to the relief of the body of any one; ever wind and cold alone.
Many would plunge their limbs burning with disease into the cool rivers, throwing their body naked into the water.
[1174] Many tumbled headforemost deep down into the wells, meeting the water straight with mouth wide agape.
Parching thirst with a craving not to be appeased, drenching their bodies, would make an abundant draught no better than the smallest drop.
No respite was there of ill: their bodies would lie quite spent.
The healing art would mutter low in voiceless fear, as again and again they rolled about their eye-balls wide open, burning with disease, never visited by sleep.
And many symptoms of death besides would then be given, the mind disordered in sorrow and fear, the clouded brow, the fierce delirious expression, the ears too troubled and filled with ringings, the breathing quick or else strangely loud and slow-recurring, and the sweat glistening wet over the neck, the spittle in thin small flakes, tinged with a saffron-color, salt, scarce forced up the rough throat by coughing.
