The Firefly Encyclopedia of Astronomy

Before streets were brightly illuminated at night, astronomy was accessible to everyone and was a matter of great importance: for divination; for setting appropriate dates for planting, harvest, and festivals; for regulating lives. Phenomena in the heavens are still of great importance to many, and much of the lore of astronomy and astrology dates back to the earliest days of civilization. The astronomy of the ancients is thus of interest not only as history but also as the basis for much of what is known or believed about the heavens today. Because phenomena in the heavens are less familiar today than in earlier eras, this book begins with a brief description of what one can see in the sky on dark nights with the naked eye.
