History of Astronomy - Early History

Early History

Early cultures identified celestial objects with gods and spirits. They related these objects (and their movements) to phenomena such as rain, drought, seasons, and tides. It is generally believed that the first "professional" astronomers were priests, and that their understanding of the "heavens" was seen as "divine", hence astronomy's ancient connection to what is now called astrology. Ancient structures with possibly astronomical alignments (such as Stonehenge) probably fulfilled both astronomical and religious functions.

Calendars of the world have usually been set by the Sun and Moon (measuring the day, month and year), and were of importance to agricultural societies, in which the harvest depended on planting at the correct time of year. The most common modern calendar is based on the Roman calendar, which divided the year into twelve months of alternating thirty and thirty-one days apiece. In 46 BC Julius Caesar instigated calendar reform and adopted a calendar based upon the 365ΒΌ day year length originally proposed by 4th century BC Greek astronomer Callippus.

Famous quotes containing the words early and/or history:

    “The secret of heaven is kept from age to age. No imprudent, no sociable angel ever dropt an early syllable to answer the longings of saints, the fears of mortals. We should have listened on our knees to any favorite, who, by stricter obedience, had brought his thoughts into parallelism with the celestial currents, and could hint to human ears the scenery and circumstance of the newly parted soul.”
    —Ralph Waldo Emerson (1803–1882)

    “What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
    —Boris Pasternak (1890–1960)
