ANALYSIS
XXIII. ‘But here’, said I, ‘is a better point to disprove the alleged reflexion from the moon; it is found that those who stand in reflected rays, not only see the illuminated but also the illuminating body. For instance, when light from water [Sidenote: C] leaps on to a wall, and the eye is placed in the spot so illuminated by reflexion, it sees the three objects, the reflected rays, the water which caused the reflexion, and the sun himself, from whom proceeds the light so falling on the water and reflected. All this being granted and apparent, people require those who contend that the earth receives the moon’s light by reflexion, to point out the sun appearing in the moon at night, as he appears in the water by day when he is reflected off it. Then, as he does not so appear, they suppose that the illumination is caused by some process other than reflexion, and that, failing reflexion, [Sidenote: D] the moon is no earth.’
‘What answer then is to be given to them?’ said Apollonides, ‘for the difficulty about reflexion seems to apply equally to us.’ ‘Equally no doubt in one sense,’ I answered, ‘but in another sense not at all so. First look at the details of the simile, how “topsy turvy”[351] it is, rivers flowing up stream! The water is below and on earth, the moon is above the earth and poised aloft. So the angles of reflexion are differently formed; in the one case the apex is above in the moon, in the other below on the earth. They should not then require that mirrors should produce every image and like reflexions at any distance, since [Sidenote: E] they are fighting against clear fact. But from those like ourselves who seek to show that the moon is not a fine smooth substance like water, but heavy and earth-like, it is strange to ask for a visible appearance of the sun in her. Why, milk does not return such mirrored images, nor produce optical reflexion, the reason being the unevenness and roughness of its parts. How can the moon possibly send back the vision off [Sidenote: F] herself as the smoother mirrors do?
We know that even in these, if any scratch or speck or roughness is found at the point from which the vision is naturally reflected it is obscured; the blemishes are seen, but they do not return the light. A man who requires that she should either turn our vision back to the sun, or else not reflect the sun from herself to us, is a humorist; he wants our eye to be the sun, the image light, man heaven! That the reflexion of the sun’s light conveyed to the moon with the impact of his intense brilliance should be borne back to us is reasonable enough, whereas our sight is weak and slight and merely fractional. What wonder if it deliver a stroke which has no resilience, or, if it does rebound, no continuity, but is broken up and fails, having no store of light to make up for dispersion about the rough and uneven [Sidenote: 937] places. For it is not impossible that the reflexion should rebound to the sun from water and other mirrors, being still strong and near its point of origin; whereas from the moon, even if there are glancings of a sort, yet they will be weak and dim, and will fail by the way because of the long distance.
Another point: concave mirrors return the reflected light in greater strength than the original, and thus often produce [Sidenote: B] flames; convex and spherical mirrors one which is weak and dim, because the pressure is not returned from all parts of the surface. You have seen, no doubt, how when two rainbows appear, one cloud enfolding another, the enveloping bow shows the colours dim and indistinct, for the outer cloud lying further from the eye does not return the reflexion in strength or intensity. But enough! Whereas the light of the sun reflected from the moon loses its heat entirely, and only a scanty and ineffectual remnant of its brilliance reaches us, do you really think it possible that when sight has the double course to travel, [Sidenote: C] any remnant whatever should reach the sun from the moon? No! say I. Look for yourselves’, I went on. ‘If the effects of the water and of the moon on our sight were the same, the full moon ought to show us images of earth and plants and men and stars, as other mirrors do. If, on the other hand, our vision is never carried back on to these objects, whether because of its own feebleness or of the roughness of the moon’s surface, then let us never demand that it should be carried by reflexion on to the sun.
_Fallings of men, lives trampled to the dust_,[354] men tumbling off through the air and turning somersaults. Yet [Sidenote: 938] it is ridiculous to raise a discussion about their remaining there, if they can neither come into being nor subsist at all. When we see Egyptians and Troglodytes, over whose heads the sun stands for the space of one brief day at the solstice and then passes on, all but shrivelled up by the dryness of the air around them, is it likely, I ask you, that people in the moon can endure twelve summers in each year, the sun standing plumb straight above them at every full moon? Then as to winds and clouds and [Sidenote: B] showers, without which plants can neither receive nor maintain existence, it is out of the question to conceive of their being formed, because the surrounding atmosphere is too hot and too rare. For even here the highest mountain tops do not get our fierce and conflicting storms, the air being already in turmoil from its lightness escapes any such condensation. Or are we really to say that, as Athena dropped a little nectar and ambrosia into Achilles’ mouth when he was refusing nourishment, even so the moon, who is called and who is Athena,[355] feeds man by sending up ambrosia day by day, in which form old Pherecydes [Sidenote: C] thinks that the Gods take food! For as to that Indian root, of which Megasthenes tells us that men, who neither eat nor drink but are without mouths,[356] burn a little, and make a smoke, and are nourished by the smells, how is it to be found growing there if there is no rain on the moon?’
XXV. When Theon had finished: ‘Well and kindly done,’ I said, ‘to unbend our brows by your witty argument; it makes us bold in reply, since we have no very harsh or severe criticism to expect. It is a true saying that there is little to choose between those who are vehemently convinced in such matters and those who are vehemently offended at them and incredulous, and will not look quietly into the possibilities. To begin, supposing that men do not inhabit the moon, it does not follow [Sidenote: D] that she has come into being just for nothing. Why, our earth, as we see, is not in active use or inhabited in her whole extent; but a small part of her only, mere promontories or peninsulas which emerge from the abyss, is fertile in animals and plants; of the other parts, some are desert and unfruitful owing to storms and droughts, while most are sunk under the ocean. But you, lover and admirer of Aristarchus that you are, do not attend to Crates and his reading: _Ocean, the birth and being of us all, Both men and Gods, covers the most of earth._[357]
‘However, this is a long way from saying that all has been brought into being for nothing. The sea sends up soft exhalations, [Sidenote: E] and delightful breezes in midsummer heat; from the uninhabited and icebound land snows quietly melt which open and fertilize all; earth stands in the midst, in Plato’s[358] words, “unswerving guardian and maker of day and night”. Nothing then prevents the moon too, though barren of animal life, from allowing the light around her to be reflected and to stream [Sidenote: F] about, and the rays of the stars to flow together and to be united within her; thus she combines and digests the vapours proceeding from earth, and at the same time gets rid of what is scorching and violent in the sun’s heat. And here we will make bold to yield a point to ancient legend, and to say that she has been held to be Artemis, a maiden and no mother, but in other ways helpful and serviceable. For, surely, nothing which has been said, dear Theon, proves it to be impossible that she is inhabited in the way alleged.
For her revolution is one very gentle and calm; which smoothes the air, and duly [Sidenote: 939] blends and distributes it, so that there is no fear of those who have lived there falling or slipping off her. If not this, neither are the changes and variety of her orbit due to anomaly or confusion, but astronomers make us see a marvellous order and progress in it all, as they confine her within circles which roll around other circles, according to some not herself stirring, according to others moving gently and evenly and with uniform speeds. For these circles and revolutions, and their relations to one another, and to us, work out with very great accuracy the phenomena of her varying height and depth and her [Sidenote: B] passages in latitude as well as in longitude. As to the great heat and continuous charring caused by the sun, you will no longer fear these if you will set against the [eleven][359] summer conjunctions the full-moons, and the continuity of the change, which does not allow extremes to last long, tempering both extremes, and producing a convenient temperature, while between the two the inhabitants enjoy a climate nearly resembling our spring.
In the next place, the sun sends down to us, and drives home through her thick and resisting atmosphere, heat fed [Sidenote: C] by exhalations; but there a fine and transparent air scatters and distributes the stream of light, which has no body or fuel beneath it. As to woods and crops, here where we live they are nourished by rains, but in other places, as far up as round your Thebes and Syene, the earth drinks water which comes out of herself, not from rain; it enjoys winds and dews, and would not, I think, thank us for comparing it in fruitfulness with our own, even where the rainfall is heaviest. With us, plants of the same order, if severely pinched by winter frosts, [Sidenote: D] bring forth much excellent fruit, while in Libya, and with you in Egypt, they bear cold very badly and shrink from the winters. Again, while Gedrosia, and Troglodytis which reaches down to ocean, are unproductive and treeless in all parts because of the drought, yet, in the adjacent and surrounding sea, plants grow to a marvellous size and luxuriate in its depths; some of these called “olive-trees”, some “laurels”, some “hair of Isis”.
_Dew feeds them, born of Zeus and Lady Moon_, that here he calls the atmosphere Zeus, and says that it is liquefied and turned into dew by the moon. Probably, my friend, her nature is opposite to the sun’s, since not only does he naturally consolidate and dry things which she softens and [Sidenote: B] disperses, but she also liquefies and cools his heat, as it falls upon her from him, and mingles with herself. Certainly they are in error who hold that the moon is a fiery and charred body; and those who require for animals there all the things which they have here, seem to lack eyes for the inequalities of Nature, since it is possible to find greater and more numerous divergencies and dissimilarities between animals and animals than between them and the inanimate world. And grant that men without mouths and nourished on smells are not to be found—I do not [Sidenote: C] think they are—, but the potency which Ammonius himself used to expound to us has been hinted at by Hesiod[361] in the line _Nor yet in mallow and in asphodel How great the virtue._
They think that those who came with Hercules and were left behind by him, mingled later on with the subjects of Cronus, and rekindled, so to speak, the Hellenic life which was becoming extinguished and overborne by barbarian languages, laws, and ways of life, and so it again became strong and vigorous. Thus the first honours are paid to Hercules, the second to Cronus. When the star of Cronus, called by us the Shining One, by them, as he told us, the Night Watcher, has reached Taurus again after an interval of thirty years, having for a long time before made preparation for [Sidenote: D] the sacrifice and the voyage, they send forth men chosen by lot in as many ships as are required, putting on board all the supplies and stuff for the great rowing voyage before them, and for a long sojourn in a strange land. They put out, and naturally do not all fare alike; but those who come safely out of the perils of the sea land first on the outlying islands, which are inhabited by Greeks, and day after day, for thirty days, see the sun hidden for less than one hour.
This is the night, with a darkness which is slight and of a twilight hue, and has a light over it from the West. There they spend ninety days, [Sidenote: E] meeting with honourable and kindly treatment, and being addressed as holy persons, after which they pass on, now with help from the winds. There are no inhabitants except themselves, and those who have been sent before them. For those who have joined in the service of the God for thirty years are allowed to sail back home, but most prefer to settle quietly in the place where they are, some because they have grown used to it, some because all things are there in plenty without pain or trouble, while their life is passed in sacrifices and festivals, or given to literature or Philosophy. For the natural beauty [Sidenote: F] of the isle is wonderful, and the mildness of the environing air. Some, when they are of a mind to sail away, are actually prevented by the God, who manifests himself to them as to familiars and friends, not in dreams only or by signs, for many meet with shapes and voices of spirits, openly seen and heard.
‘Now the stranger, having been received here, as he told us, and serving the God at his leisure, attained as much skill in astronomy as is attainable by the most advanced geometry; of other Philosophy he applied himself to the physical branches. Then, having a strange desire and yearning to see “the Great Island” (for so it appears they call our world), when the thirty years were passed, and the relief parties arrived from home, he said farewell to his friends and sailed forth, carrying a complete equipment of all kinds, and abundant store of provision for the way in golden beakers. All the adventures which befell him, and all the men whose lands he visited, how he met with [Sidenote: C] holy writings and was initiated into all the mysteries, it would take more than one day to enumerate as he did, well and carefully and with all details. Listen now to those which concern our present discussion. He spent a very long time in Carthage.[367]... He there discovered certain sacred parchments which had been secretly withdrawn when the older city was destroyed, and had lain a long time in the earth unnoticed; and he said that of all the Gods who appear to us we ought specially to honour the moon with all our substance (and so he charged me to do), because she was most potent in our life.
_Now to Elysian plains, earth’s utmost bound._ For where the shadow of the earth rests in its passage, there Homer placed the limit and boundary of earth. To that limit comes no man that is bad or impure, but the good after death are conveyed thither, and pass a most easy life, not, however, one blessed or divine until the second death.”‘ XXVIII. ‘But what is that, Sylla?’ ‘Ask me not of these things, for I am going to tell you fully myself. The common [Sidenote: 943] view that man is a composite creature is correct, but it is not correct that he is composed of two parts only. For they suppose that mind is in some sense a part of soul, which is as great a mistake as to think that soul is a part of body; mind is as much better a thing and more divine than soul, as soul is than body. Now the union of soul with body makes up the passion or emotion, the further union with mind produces reason; the former is the origin of pleasure and pain, the latter of virtue and vice. When these three principles have been compacted, the earth contributes body to the birth of man, the moon soul, the sun reason, just as he contributes her light to the moon.
The death which we die is of two kinds; the one [Sidenote: B] makes man two out of three, the other makes him one out of two; the one takes place in the earth which is the realm of Demeter, and is initiation unto her,[369] so that the Athenians used in ancient times to call the dead “Demetrians”, the other is in the moon, and is of Persephone; Hermes is the associate on earth of the one, of the other in heaven. Demeter parts soul from body quickly and with force; Persephone parts mind from soul gently and very slowly, and therefore has been called[370] “Of the Birth to Unity”, for the best part of man is left in oneness, when separated by her. Each process happens according to [Sidenote: C] Nature, as thus: It is appointed that every soul, irrational or rational, when it has quitted the body, should wander in the region between earth and moon, but not all for an equal time; unjust and unchaste souls pay penalties for their wrongdoings; but the good must for a certain appointed time, sufficient to purge away and blow to the winds, as noxious exhalations, defilements from the body, which is their vicious cause, be in that mildest part of the air which they call “The Meadows of Hades”; then they return as from long and distant exile back to their country, they taste [Sidenote: D] such joy as men feel here who are initiated, joy mingled with much amazement and trouble, yet also with a hope which is each man’s own. For many who are already grasping at the moon she pushes off and washes away, and some even of those souls which are already there and are turning round to look below are seen to be plunged again into the abyss.
But those which have passed above, and have found firm footing, first go round like victors wreathed with crowns of feathers called “crowns of constancy”, because they kept the irrational part of the soul obedient to the curb of reason, and well ordered in life. Then with countenance like a sunbeam, and soul borne lightly upwards by fire, as here, namely that of the air about [Sidenote: E] the moon, they receive tone and force from it, as iron takes an edge in its bath; for that which is still volatile and diffuse is strengthened and becomes firm and transparent, so that they are nourished by such vapour as meets them, and well did Heraclitus[371] say that “Souls feed on smell in Hades.” XXIX. First they look on the moon herself, her size, her beauty, and her nature, which is not single or unmixed, but as it were a composition of earth and star. For as the earth has become soft by being mixed with air and moisture, and as the blood infused into the flesh produces sensibility, so the moon, they say, being mingled with air through all her depth, is endowed with soul and with fertility, and at the same time [Sidenote: F] receives a balance, lightness set against weight. Even so the universe itself, duly framed together of things having some an upward tendency, some a downward, is freed from all movement of place. This Xenocrates apprehended, it would seem, by some divine reasoning, having received the suggestion from Plato. For it is Plato[372] who showed that every star has been compounded of earth and fire by means of intermediate natures given in proportion, since nothing reaches the senses into which earth and light do not enter.
But Xenocrates says that the stars and the sun are compounded out of fire and the [Sidenote: 944] first density, the moon out of the second density and her own air, and earth out of water, fire, and the third density; and that as an universal law, neither the dense alone nor the rarefied alone is capable of receiving soul. So much then for the substance of the moon. But her breadth and bulk are not what geometricians say, but many times greater. The reason why she but seldom measures the shadow of the earth with [three of] her own diameters, is not its smallness, but her heat, whereby she increases her speed that she may swiftly pass through and beyond the dark region, bearing from out it the souls of the good, as they hasten and cry aloud, for being in the shadow they no longer hear the harmony of heaven. At the same [Sidenote: B] time there are borne up from below through the shadow the souls of those who are to be punished, with wailing and loud cries. Hence comes the widespread custom of clanking vessels of brass during eclipses, with a din and a clatter to reach the souls.
Also the face, as we call it, terrifies them, when they are near, so grim and weird is it to their sight. Really it is nothing of the kind; but as our earth has gulfs deep and great, one here which streams inwards towards us from the Pillars of Hercules, [Sidenote: C] outwards the Caspian, and those about the Red Sea, even such are those depths and hollows of the moon. The largest of them they call the Gulf of Hecate, where the souls endure and exact retribution for all the things which they have suffered or done ever since they became spirits; two of them are long, through which the souls pass, now to the parts of the moon which are turned toward heaven, now back to the side next to earth. The parts of the moon toward heaven are called “the Elysian plain”, those toward earth “the plain of Persephone Antichthon”.
_Winged as a dream the soul takes flight away._[373] Not at the first, and not when it is quit of the body does this happen to it, but afterwards when it becomes deserted and solitary, set free from mind. Of all that Homer has told us I think that there is nothing more divine than where he speaks of those in Hades: _Next was I ware of mighty Hercules, His ghost—himself among the immortals dwells._[374] For the self of each of us is not courage, nor fear, nor desire, any more than it is a parcel of flesh and of humours; it is that whereby we understand and think. The soul being shaped by [Sidenote: 945] the mind and itself shaping the body and encompassing it upon all sides, stamps its form upon it, so that even if it is separated from both for a long time, yet it possesses the likeness and the stamp, and is rightly called an image. Of these, the moon, as has been said, is the element, for they are resolved into her just as are the bodies of the dead into earth; the temperate speedily, those who embraced a life of quiet and Philosophy; for, having been set free by mind, and having no further use for the passions, they wither away. But of the ambitious, [Sidenote: B] and active, and sensuous, and passionate, some are distracted as though in sleep, dreaming out their memories of life, as the soul of Endymion; but when their restless and susceptible nature starts them out of the moon and draws them to another birth, she does not suffer it, but draws them back and soothes them.
