The Zodiac
Early astronomers divided the ecliptic - the path followed by the Sun across the sky - into twelve zones with each zone occupying 30 degrees of the ecliptic. Each of these regions corresponds loosely to one of the twelve months of the year, and is given one of the familiar names - Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces.The signs of the zodiac originally coincided with their associated constellations - star pattern.
