8 They ought to have felt astonishment and admiration not only at the arrangement of sun and moon, but also at the well-ordered choirs of the stars, their unimpeded courses, and their risings in the seasons due to each: and how some are signs of summer, and others of winter; and how some mark the season for sowing, and others show the commencement of navigation. And a man sitting in his ship, and sailing amid the boundless waves, steers his ship by looking at the stars. For of these matters the Scripture says well, And let them be for signs, and for seasons, and for years, not for fables of astrology and nativities. But observe how He has also graciously given us the light of day by gradual increase: for we do not see the sun at once arise; but just a little light runs on before, in order that the pupil of the eye may be enabled by previous trial to look upon his stronger beam: see also how He has relieved the darkness of the night by rays of moonlight.
