‘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
