(Latin: "Water carrier") In astronomy, the constellation lying between Capricorn and Pisces; in astrology , the 11th sign of the zodiac , governing approximately the period January 20–February 18.
It is usually represented as a man pouring a stream of water out of a jug, probably because in ancient times the rising of Aquarius coincided in the Middle East with the annual arrival of floods or rainfall. In the astrological concept called the Great Year
the 25,000-year period it takes the earth to pass through the influence of the entire zodiac
the early 19th century was the beginning of the Age of Aquarius.
