The zodiac is divided into 12 segments, or signs, each named after a constellation in the sky. These signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
The origins of the zodiac can be traced back to the ancient Mesopotamians, who used the positions of the celestial bodies in the sky to track the passing of time and to predict future events. The Mesopotamians believed that the movements of the celestial bodies were connected to the lives of people on earth and that they could be used to forecast important events and changes.
Over time, the zodiac system was adopted by other cultures, including the ancient Greeks, who made significant contributions to the development of astrology.
