(4) But what slipped from our view in the midst of our discourse, the Good is Cause of the celestial movements in their commencements and terminations, of their not increasing, not diminishing, and completely changeless, course, and of the noiseless movements, if one may so speak, of the vast celestial transit, and of the astral orders, and the beauties and lights, and stabilities, and the progressive swift motion of certain stars, and of the periodical return of the two luminaries, which the Oracles call "great," from the same to the same quarter, after which our days and nights being marked, and months and years being measured, mark and number and arrange and comprehend the circular movements of time and things temporal. But, what would any one say of the very ray of the sun? For the light is from the Good, and an image of the Goodness, wherefore also the Good is celebrated under the name of Light; as in a portrait the original is manifested. For, as the goodness of the Deity, beyond all, permeates from the highest and most honoured substances even to the lowest, and yet is above all, neither the foremost outstripping its superiority, nor the things below eluding its grasp, but it both enlightens all that are capable, and forms and enlivens, and grasps, and perfects, and is measure of things existing, and age, and number, and order, and grasp, and cause, and end; so, too, the brilliant likeness of the Divine Goodness, this our great sun, wholly bright and ever luminous, as a most distant echo of the Good, both enlightens whatever is capable of participating in it, and possesses the light in the highest degree of purity, unfolding to the visible universe, above and beneath, the splendours of its own rays, and if anything does not participate in them, this is not owing to the inertness or deficiency of its distribution of light, but is owing to the inaptitude for light-reception of the things which do not unfold themselves for the participation of light. No doubt the ray passing over many things in such condition, enlightens the things after them, and there is no visible thing which it does not reach, with the surpassing greatness of its own splendour. Further also, it contributes to the generation of sensible bodies, and moves them to life, and nourishes, and increases, and perfects, and purifies and renews; and the light is both measure and number of hours, days, and all our time. For it is the light itself, even though it was then without form, which the divine Moses declared to have fixed that first Triad of our days. And, just as Goodness turns all things to Itself, and is chief collector of things scattered, as One-springing and One-making Deity, and all things aspire to It, as Source and Bond and End, and it is the Good, as the Oracles say, from Which all things subsisted, and are being brought into being by an all-perfect Cause; and in Which all things consisted, as guarded and governed in an all-controlling route; and to Which all things are turned, as to their own proper end; and to Which all aspire --the intellectual and rational indeed, through knowledge, and the sensible through the senses, and those bereft of sensible perception by the innate movement of the aspiration after life, and those without life, and merely being, by their aptitude for mere substantial participation; after the same method of its illustrious original, the light also collects and turns to itself all things existing--things with sight -- things with motion--things enlightened--things heated--things wholly held together by its brilliant splendours--whence also, Helios, because it makes all things altogether (ἀολλῆ), and collects things scattered. And all creatures, endowed with sensible perceptions, aspire to it, as aspiring either to see, or to be moved and enlightened, and heated, and to be wholly held together by the light. By no means do I affirm, after the statement of antiquity, that as being God and Creator of the universe, the sun, by itself, governs the luminous world, but that the invisible things of God are clearly seen from the foundation of the world, being understood by the things that are made, even His eternal power and Deity.

(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.

(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.

(507) additional nature in order that the one may be able to hear and the other to be heard? Nothing of the sort. No, indeed, I replied; and the same is true of most, if not all, the other senses—you would not say that any of them requires such an addition? Certainly not. But you see that without the addition of some other nature there is no seeing or being seen? How do you mean? Sight being, as I conceive, in the eyes, and he who has eyes wanting to see; colour being also present in them, still unless there be a third nature specially adapted to the purpose, the owner of the eyes will see nothing and the colours will be invisible. Of what nature are you speaking? Of that which you term light, I replied. True, he said. Noble, then, is the bond which links together sight and visibility, and great beyond other bonds by no small difference of nature; for light is their bond, and light is no ignoble thing? Nay, he said, the reverse of ignoble. And which, I said, of the gods in heaven would you say was the lord of this element? Whose is that light which makes the eye to see perfectly and the visible to appear? You mean the sun, as you and all mankind say. May not the relation of sight to this deity be described as follows? How?

(32) "Light," writes Edwin D. Babbitt, "reveals the glories of the external world and yet is the most glorious of them all. It gives beauty, reveals beauty and is itself most beautiful. It is the analyzer, the truth-teller and the exposer of shams, for it shows things as they are. Its infinite streams measure off the universe and flow into our telescopes from stars which are quintillions of miles distant. On the other hand it descends to objects inconceivably small, and reveals through the microscope objects fifty millions of times less than can be seen by the naked eye. Like all other fine forces, its movement is wonderfully soft, yet penetrating and powerful. Without its vivifying influence, vegetable, animal, and human life must immediately perish from the earth, and general ruin take place. We shall do well, then, to consider this potential and beautiful principle of light and its component colors, for the more deeply we penetrate into its inner laws, the more will it present itself as a marvelous storehouse of power to vitalize, heal, refine, and delight mankind." (See The Principles of Light and Color.)

(4) Panvotrus saith:—I signify to posterity that air is a tenuous matter of water, and that it is not separated from it. It remains above the dry earth, to wit, the air hidden in the water, which is under the earth. If this air did not exist, the earth would not remain above the humid water. They answer:—Thou hast said well; complete, therefore, thy speech. Sut he continueth: The air which is hidden in the water under the earth is that which sustains the earth, lest it should be plunged into the said water; and it, moreover, prevents the earth from being overflowed by that water. The province of the air is, therefore, to fill up and to make separation between diverse things, that is to say, water and earth, and it is constituted a peacemaker between hostile things, namely, water and fire, dividing these, lest they destroy one another.

The Turba saith:—If you gave an illustration hereof, it would be clearer to those who do not understand.

He answereth:—An egg is an illustration, for therein four things are conjoined; the visible cortex or shell represents the earth, and the albumen, or white part, is the water.* But a very thin inner cortex is joined to the outer cortex, representing, as I have signified to you, the separating medium between earth and water, namely, that air which divides the earth from the water. The yolk also of the egg represents fire; the cortex which contains the yolk corresponds to that other air which separates the water from the fire. But they are both one and the same air, namely, that which separates things frigid, the earth from the water, and that which separates the water from the fire. But the lower air is thicker than the upper air, and the upper air is more rare and subtle, being nearer to the fire than the lower air. In the egg, therefore, are four things—earth, water, air, and fire. But the point of the Sun, these four excepted, is in the centre of the yolk, and this is the chicken. Consequently, all philosophers in this most excellent art have described the egg as an example, which same thing they have set over their work.

(29) For the Stars themselves are senseless, and have no Knowledge or Perception, yet their soft Operation in the Water makes a seething, flowing forth, or boiling up one of another, and in the Tincture of the Blood, they cause a Rising, Seeing, Feeling, Hearing, and Tasting. Therefore consider from whence the Tincture proceeds, wherein the noble Life springs up, that thus becomes sweet from Harshness, Bitterness, and Fire, and you shall certainly find no other Cause of it than the Light: But whence comes the Light, that it can shine in a dark Body? If you say it comes from the Light of the Sun. Then what shines in the Night, and enlightens your Senses and Understanding so, that though your Eyes are shut, you perceive and know what you do? Here you will say, the noble Mind leads you, and it is true. But whence has the Mind its Original? You will say, the Senses make the Mind stirring; and that is also true. But whence come they both? What is their Birth or Off- spring? Why is it not so with the Beasts?

(3) Since, however, a contrary is receptive of a contrary, according to a mutation and departure from itself, and that which is allied to another thing, and familiar with it through similitude, is capable of receiving it, hence the illuminators receive darkness as a cooperator, and employ in illuminating the light of the sun, or of the moon, or, in short, of the air. Sometimes, likewise, they use collocations of such things as are adapted to the Gods that are about to descend, or they employ incantations or compositions, and these appropriately prepared for the reception, presence, and manifestation of the Gods. And again, sometimes they introduce light through water, because this being diaphanous, is aptly disposed to the reception of light. But at other times, they cause light to shine forth on a wall, having previously prepared the wall for the reception of light in the best manner by the sacred descriptions of characters; and, at the same time, they fix the light in a certain solid place, so that it may not be widely diffused.
