Here's a breakdown of the key players and developments:
* Ancient Babylonians (2nd millennium BCE): They were the first to divide the ecliptic (the apparent path of the Sun through the stars) into 12 sections, each associated with a constellation. They also developed the concept of the zodiac, which was a celestial calendar used to track the movement of planets and the seasons.
* Ancient Greeks (4th century BCE): They adopted the Babylonian zodiac and incorporated it into their own astronomical and astrological systems. They also assigned specific traits and characteristics to each sign, laying the foundation for the modern understanding of zodiac signs.
* Later developments: The zodiac has been refined and reinterpreted over the centuries by various cultures and civilizations, including the Romans, Egyptians, and Arabs. The specific traits associated with each sign have evolved over time, influenced by cultural beliefs and societal norms.
Therefore, it's inaccurate to attribute the zodiac to a single person. It is the result of a long and collaborative effort by various ancient cultures, each contributing to its development and evolution.
