Using the astrological constellations to chart the fate an destinies of people was wide spread in the ancient world. Though the Sumerians and Babylonians are actually credited with the development of this science, it was the Greeks who derived the word zodiac with actually means the
"circle of animals".
The naming of astrological constellations with both human and animal terms was refined by Greek philosophers such as Aristotle who developed the science into what we know today. The science was further refined by the Romans who gave the 12 signs the names that were are familiar with today:
Aquarius (the water bearer),
Pisces (the fish),
Aries (the ram),
Taurus (the bull),
Gemini (the twins),
Cancer (the crab),
Leo (the lion),
Virgo (the virgin),
Libra (the scales),
Scorpio (the scorpion),
Sagittarius (the archer), and
Capricorn (the goat).
