(19) Air has its original from heat and cold; for heat and cold work powerfully and replenish all, whereby is caused a lively and stirring motion; but when cold allayeth or mitigateth the heat, then both their qualities are rarefied and made thin; and the bitter quality attracteth or concreteth them together, so that they become dewy.

(54) Now when the light shineth through the astringent, contracted body of nature, and mitigateth it, then the mild, beneficent welldoing generateth itself in the body, and then the hard power grows very mild, and melteth, as ice in the heat of the sun, and is extenuated or rarefied, as water is in the air; and yet the stock of nature, as to the heavenly comprehensibility, remaineth the same.

(1) Moreover, with respect to the tenuity and subtilty of light, the Gods extend a light so subtle that corporeal eyes cannot sustain it, but are affected in the same manner as fishes, when they are drawn upward from turbid and thick water into attenuated and diaphanous air. For men who survey divine fire are not able to breathe, through the subtilty of it, but become languid as soon as they perceive it, and are deprived of the use of their connascent spirit. Archangels, also, emit a light which is intolerable to respiration, yet their splendour is not equally pure with that of the Gods, nor similarly overpowering. The presence of angels renders the temperature of the air tolerable, so that theurgists are capable of being united to it. But when dæmons are present, the whole air is not at all affected; nor does the air, which surrounds them, become more attenuated; nor does a light precede them, in which, being previously received and preoccupied by the air, they unfold the form of themselves; nor are they surrounded by a certain splendour, which diffuses its light everywhere. When heroes appear, certain parts of the earth are moved, and sounds are heard around them; but, in short, the air does not become more attenuated, nor incommensurate to theurgists, so as to render them unable to receive it. But when archons are present, an assemblage of many luminous appearances runs round them, difficult to be borne, whether these appearances are mundane or terrestrial. They have not, however, a supermundane tenuity, nor even that of the supreme elements. And to the psychical appearances the air is more allied, and, being suspended from them, receives in itself their circumscription.

(11) A: How meanest thou, Thrice-greatest one? H: Is not air body? A: It is. H: And doth this body not pervade all things, and so, pervading, fill them? And "body"; doth body not consist from blending of the "four" ? Full, then, of air are all thou callest void; and if of air, then of the "four". Further, of this the converse follows, that all thou callest full are void - of air; for that they have their space filled out with other bodies, and, therefore, are not able to receive the air therein. These, then, which thou dost say are void, they should be hollow named, not void; for they not only are, but they are full of air and spirit.

(21) Now these two qualities wrestle continually the one with the other, the heat consumeth the water, and the cold condenseth or crowdeth the air. Now air is the cause and spirit of every life and motion in the world, be it in flesh or in any of the vegetables; all whatever is has its life from the air, and nothing whatsoever that moveth and is in this world can subsist without air.

(74) Timaeus: and, inasmuch as it contains within it warm moisture, that it should supply in summer, by its perspiration and dampness, a congenial coolness over the exterior of the whole body, and contrariwise in winter defend the body sufficiently, by means of its fire, from the frost which attacks and surrounds it from without. Wherefore, with this intent, our Modeller mixed and blended together water and fire and earth, and compounding a ferment of acid and salt

(5) That the disturbance which below is made By exhalations of the land and water, (Which far as may be follow after heat,) Might not upon mankind wage any war, This mount ascended tow'rds the heaven so high, And is exempt, from there where it is locked. Now since the universal atmosphere Turns in a circuit with the primal motion Unless the circle is broken on some side, Upon this height, that all is disengaged In living ether, doth this motion strike And make the forest sound, for it is dense; And so much power the stricken plant possesses That with its virtue it impregns the air, And this, revolving, scatters it around; And yonder earth, according as 'tis worthy In self or in its clime, conceives and bears Of divers qualities the divers trees; It should not seem a marvel then on earth, This being heard, whenever any plant Without seed manifest there taketh root. And thou must know, this holy table-land In which thou art is full of every seed, And fruit has in it never gathered there.

(4) Besides, if rarity were of this dimness The cause thou askest, either through and through This planet thus attenuate were of matter, Or else, as in a body is apportioned The fat and lean, so in like manner this Would in its volume interchange the leaves. Were it the former, in the sun's eclipse It would be manifest by the shining through Of light, as through aught tenuous interfused. This is not so; hence we must scan the other, And if it chance the other I demolish, Then falsified will thy opinion be. But if this rarity go not through and through, There needs must be a limit, beyond which Its contrary prevents the further passing, And thence the foreign radiance is reflected, Even as a colour cometh back from glass, The which behind itself concealeth lead. Now thou wilt say the sunbeam shows itself More dimly there than in the other parts, By being there reflected farther back. From this reply experiment will free thee If e'er thou try it, which is wont to be The fountain to the rivers of your arts.

(6) But the fact that they are named winds denotes their rapid action, passing almost instantaneously to all things, and their transporting movement in passing from above to below, and again from below to above, their elevating the second to the height above, and moving the first to a common and provident advance of the inferior Orders. But perhaps some one would say that the appellation of wind, to the aerial spirit, also denotes the Divine likeness of the Heavenly Minds; for this also bears a likeness and type of the supremely Divine energy (as we have demonstrated more fully in the symbolic theology, in our explanation of the four elements) in accordance with the moving and life-producing, and the rapid and resistless development of Nature, and the Hiddenness of the moving sources and terminations to us unknown and invisible. For He says, "Thou knowest not whence it cometh nor whither it goeth." But also the Word of God attributes to them the appearance of a cloud, signifying, through this, that the holy minds are filled super-mundanely with the hidden Light, receiving the first manifestation without boasting over it as such, which they distribute ungrudgingly to the second, as a secondary manifestation, and in proportion to capacity; yea, further, that the productive, and life-producing, and increasing, and perfecting power is enshrined in them, after the fashion of the intelligible production of showers, which summons the receptive womb of the earth, by fruitful rains, to the life-giving pangs of birth.

(7) We can scarcely do better, in fine, than follow Plato.

Thus:

In the universe as a whole there must necessarily be such a degree of solidity, that is to say, of resistance, as will ensure that the earth, set in the centre, be a sure footing and support to the living beings moving over it, and inevitably communicate something of its own density to them: the earth will possess coherence by its own unaided quality, but visibility by the presence of fire: it will contain water against the dryness which would prevent the cohesion of its particles; it will hold air to lighten its bulky matters; it will be in contact with the celestial fire- not as being a member of the sidereal system but by the simple fact that the fire there and our earth both belong to the ordered universe so that something of the earth is taken up by the fire as something of the fire by the earth and something of everything by everything else.

This borrowing, however, does not mean that the one thing taking-up from the other enters into a composition, becoming an element in a total of both: it is simply a consequence of the kosmic fellowship; the participant retains its own being and takes over not the thing itself but some property of the thing, not air but air's yielding softness, not fire but fire's incandescence: mixing is another process, a complete surrender with a resultant compound not, as in this case, earth- remaining earth, the solidity and density we know- with something of fire's qualities superadded.

We have authority for this where we read:

"At the second circuit from the earth, God kindled a light": he is speaking of the sun which, elsewhere, he calls the all-glowing and, again, the all-gleaming: thus he prevents us imagining it to be anything else but fire, though of a peculiar kind; in other words it is light, which he distinguishes from flame as being only modestly warm: this light is a corporeal substance but from it there shines forth that other "light" which, though it carries the same name, we pronounce incorporeal, given forth from the first as its flower and radiance, the veritable "incandescent body." Plato's word earthy is commonly taken in too depreciatory a sense: he is thinking of earth as the principle of solidity; we are apt to ignore his distinctions and think of the concrete clay.

Fire of this order, giving forth this purest light, belongs to the upper realm, and there its seat is fixed by nature; but we must not, on that account, suppose the flame of earth to be associated with the beings of that higher sphere.

No: the flame of this world, once it has attained a certain height, is extinguished by the currents of air opposed to it. Moreover, as it carries an earthy element on its upward path, it is weighed downwards and cannot reach those loftier regions. It comes to a stand somewhere below the moon- making the air at that point subtler- and its flame, if any flame can persist, is subdued and softened, and no longer retains its first intensity, but gives out only what radiance it reflects from the light above.

And it is that loftier light- falling variously upon the stars; to each in a certain proportion- that gives them their characteristic differences, as well in magnitude as in colour; just such light constitutes also the still higher heavenly bodies which, however, like clear air, are invisible because of the subtle texture and unresisting transparency of their material substance and also by their very distance.

(8) The moving or boiling spirit, which before qualified or operated very meekly in nature, became, in its outermost birth or geniture, very exhalted and terrible, which now, in the outermost birth, is called the wind, or the element of air, in regard of its elevation or expansion.

(64) Continuing: "Philosophers say there is no true solution of the body without a proceeding coagulation of the spirit, for they are interchangeably mixed in a due proportion, whereby the bodily essence becomes of a spiritual penetrating nature. On the other hand, the incomprehensible spiritual essential virtue is also made corporeal by the fire, because there is made between them so near a relation or friendship, like as the heavens operate to the very Depth of Earth, and producing from thence all the treasures and riches of the whole World.
