Commentary on Genesis

Cyril of Jerusalem (313–386)

Men ought to have been astonished and amazed not only at the arrangement of the sun and moon but also at the well-ordered movements of the stars and their unfettered courses and the timely rising of each of them; how some are signs of summer, others of winter; how some indicate the time for sowing, others the times of navigation.
