Implicitly or explicitly, the rhythms of our lives, the movement from season to season, the patterns of the winds, and the pulse of the tides all depend on the apparent motions of the sun and moon and stars. Yet most modern urban dwellers are only dimly aware of the night sky ? the stars and their myriad forms. They are only slightly more aware of the phases of the moon or the motions of the sun. Even those who take the daily horoscope seriously generally have a very poor notion of its connection with astronomical phenomena.
