XXIV. ‘We have now’, I said, ‘reported all that was said then, and has not escaped our memory. It is time to call on Sylla, or rather to claim his story, as he was allowed to be a listener on terms. So, if it meet your approval, let us cease our walk, and take our places on the benches and give him a seated |D| audience.’ This was at once agreed, and we had taken our seats, when Theon said: ‘I want as much as any of you, Lamprias, to hear what is now to be said, but first I should like to hear about the alleged dwellers in the moon, not whether there are any such, I mean, but whether there can be; for if the thing is impossible, then it is also absurd that the moon should be an earth; it will appear that she has been created for no end or use, if she bears no fruit, offers no abode to human beings, no existence, no livelihood, the very things for which we say that she has been created, in Plato’s[[352]] words, “our nurse, and of |E| day and night the unswerving guardian and maker”. You see that many things are said about this, some in jest, some seriously. For instance, that the moon hangs poised over the heads of those who dwell beneath her, as if they were so many Tantali; while as for those who dwell on her, they are lashed on like Ixions by the tremendous speed. Yet hers is not a single motion, but, as |F| it is somewhere put, she is a Goddess of the Three Ways. She moves in longitude over the Zodiac, in latitude, and in depth; one movement is revolution, another a spiral, the third is strangely named “Anomaly” by scientific men, although there is nothing irregular or confused to be seen in her returns to her stations. Therefore it is no wonder if a lion[[353]] did once fall on to Peloponnesus, owing to the velocity; the wonder is that we do not see every day
Fallings of men, lives trampled to the dust,[[354]]
men tumbling off through the air and turning somersaults. Yet |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 |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 |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 |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, |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 |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 |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 |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 |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, |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”. But the “love-come-back” as it is called, if taken out of the earth, not only lives when hung up for as long as you please, but also sprouts. Some are sown close on |E| to winter, some in the height of summer, sesame or millet for instance; thyme or centaury, if sown in a good rich soil and watered, changes its qualities and strength; both rejoice in drought and reach their proper growth in it. But if, as is said, like most Arabian plants, they do not endure even dews, but fade and perish when moistened, what wonder, I ask, if roots and seeds and trees grow on the moon which need no rains or snows, but are fitted by Nature for a light and summer-like atmosphere? Why, again, may it not be probable that breezes ascend warmed by the moon and by the whirl of her revolution, and that she is accompanied by quiet breezes, which shed dews and moisture around, and when |F| distributed suffice for the grown plants, her own climate being neither fiery nor dried up, but mild and engendering moisture. For no touch of dryness reaches us from her, but many effects of moisture and fertility, as increase of plants, putrefaction of flesh, turning of wine to flatness, softening of wood, easy delivery to women. I am afraid of stirring Pharnaces to the fray |940| again, now that he is quiet, if I enumerate as cases of restoring moisture the tides of the ocean (as his own school describes them), and the fillings of gulfs when their flood is augmented by the moon. So I will rather turn to you, dear Theon, for you told us in explaining these words of Alcman,[[360]]
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 |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 |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
