"From there on, Astrologers created charts called horoscopes, which map the position of astronomical bodies at certain times, such as when a person is born. The horoscope is illustrated by a circle, called the ecliptic.

The ecliptic is the plane on which the earth orbits around the sun in a year. It is divided into twelve sections, called the signs of the Zodiac, which include Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.

Astrologers assign every planet (which in astrology includes the sun and moon) with a particular sign, depending on where that planet appears on the ecliptic at the time for which the horoscope is cast. Each planet represents basic human drives, and each sign represents a set of human characteristics.

When astrologers designate a person as a certain sign - a Leo or a Pisces, for example - they are referring to the person’s sun sign - that is, the sign that the sun occupied at the time of the person’s birth. The horoscope also is divided into twelve houses, which make up the 24-hour period during which the earth rotates once on its axis."
