The 12 Babylonian Segments

Around 500 BC, Babylonian astronomers standardized the zodiac into 12 equal segments of 30° each. This created a mathematical grid (the Signs) separate from the irregular star groups (the Constellations).

How to read the Star Map:

  • The Sun Icon (Top): Represents the Vernal Equinox. This is our fixed viewing window (March 21st).
  • The Rotating Wheel: Represents the background stars. Precession causes this background to drift.
  • The Wedge: The segment directly behind the Sun icon tells you the current "Astrological Age."
