Sumerian Astrology

Sumerian Astrology

Your Ancient Astrology and Sumerian Language Source

Sumerian astrology is at least 5,000 years old, making it the oldest astrology on earth. Like the Sumerian Language, it was adopted and preserved by the Babylonians, who reduced the original 18-constellation Sumerian zodiac to the 12-sign Babylonian zodiac used by astrologers today.
