And yet those parts are far from having been made in vain. For the sea exhales and breathes out mild vapors; and the snow, leisurely melting from the cold and uninhabited regions, sends forth and spreads over all our countries those gentle breezes which qualify the scorching heat of summer; and in the midst, as Plato says, is placed the faithful guardian and operator of night and day. There is then nothing to hinder but that the moon may be without living creatures, and yet give reflections to the light that is diffused about her, and afford a receptacle to the rays of the stars, which have their confluence and temperature in her, for to digest the evaporation rising from the earth and moderate the over-violent and fiery heat of the sun. And attributing much to ancient fame, we will say that she is styled Diana, as being a virgin and fruitless, but otherwise greatly salutary, helpful, and profitable to the world. Moreover, of all that has been said, my friend Theon, there is nothing which shows it impossible for the moon to be inhabited. For her turning about, being gentle, mild, and calm, dulcifies and polishes the ambient air, and distributes it in so good order about her, that there is no occasion to fear the falling or slipping out of those who live in her. And as to the diversity and multiplicity of her motion, it proceeds not from any inequality, error, or uncertainty, but the astrologers show in this an admirable order and course, enclosing her within circles, which are turned by other circles; some supposing that she herself stirs not, others making her always move equally, smoothly, and with the same swiftness. For it is these ascensions of divers circles, with their turnings and habitudes, one towards another and with respect to us, which most exactly make those heights, depths, and depressions, that appear to us in her motion, and her digressions in latitude, all joined with the ordinary revolution she makes in longitude. As to the great heat and continual inflammation of the sun, you will cease to fear it, if first to the eleven estival conjunctions you oppose the full moons, and then to the excesses the continuity of change which permits them not to last long, reducing them to a proper and peculiar temperature, and taking from them both what is over much; for the middle, or what is between them, it is probable, has a season most like to the spring. And, moreover, the sun sends his beams to us through a gross and troubled air, and casts on us an heat fed by exhalation; whereas the air, being there subtile and transparent, dissipates and disperses his lustre, which has no nourishment nor body on which it may settle. Trees and fruits are here nourished by showers; but elsewhere, as in the higher countries with you about Thebes and Syene, the earth drinking in not aerial but earth-bred water, and being assisted with refreshing winds and dew, will not (such is the virtue and temperature of the
