The history of zodiac signs begins with the ancient Babylonians in the 2nd millennium BC. They were keen astronomers who mapped the night sky and recognized that it was divided into twelve sections.
The Babylonian zodiac was adopted by the Greeks in the 4th century BC. However, the Greeks transformed it from a predictive tool into a system of personality and psychological traits.
The Romans embraced the Greek zodiac and expanded its influence throughout their vast empire. They named signs in Latin, like Leo, Virgo, and Libra, which we continue to use.
Today, the zodiac signs as we know them are used in Western Astrology for natal chart interpretations. Each of the twelve signs corresponds to a specific set of dates in the year.
