The term "Zodiac" is often associated with astrology, a field of study that aims to understand human affairs by means of celestial phenomena, primarily through the positions and movements of planets, stars, and other astronomical objects. However, the origins and scope of the zodiac are broader Zodiac than this association might suggest.
A Brief History
The word "zodiac" comes from the Greek ζώδια (zōidia), which referred to a group or collection. This term was likely borrowed into Latin as zodiaca or zodiaei. The concept, however, predates these specific words and their modern connotations by several centuries.
In ancient Mesopotamia, around 1800 BCE, the Babylonians developed an elaborate system for organizing and interpreting celestial events in relation to human affairs. This system was built on a cycle of planetary and lunar cycles that determined various astrological phenomena such as the timing of agricultural cycles, auspicious periods for important life events, and even the fate of cities.
The ancient Greeks adopted this concept and refined it through their own observations and astronomical knowledge. They divided the 360-degree horizon around Earth into sections representing a circle or wheel known as zodiaei or circe. These were derived from an older system in use by the Phoenicians.
Structure
Ancient astrology’s primary objective was to chart individual destinies based on the positions of celestial bodies at the time and place of birth, often incorporating numerous tables containing calculated planetary cycles called Ephemerides for each year ahead. One common approach to organize this mass of data used various ‘houses’, twelve circular segments around a central circle known simply as Ascendant or Aspects which described an individual’s potential life path.
Early Greek astrology saw the use of the whole Earth- centered geocentric universe, dividing its horizon into two main components (two circles – one representing planets’ influence from above and the other, their direct effect). To better track movement through each particular planetary area where any event fell within a certain day or at set intervals over time. Twelve sections were thus formed by dividing a 360° circle.
