What Are Zodiac Signs? Where Did They Come From?

The twelve zodiac signs we talk about in daily life belong to the astrological system of the twelve zodiac houses. They are not exactly the same as astronomical constellations. Many people mix up astrological zodiac signs with astronomical ones. The ecliptic is the path the Sun travels across the sky over one year. Ancient people divided this path into twelve equal sections. Each section corresponds to one zodiac sign, forming the twelve zodiac houses. This system first originated in ancient Babylon. Over 2,000 years ago, Babylonians observed the movement of the sun, moon and planets, divided the ecliptic and used it for celestial recording and forecasting. Later this knowledge spread to ancient Greece. The Greeks added myths and deity stories to each house, creating the well-known zodiac mythology we know today. Astrology uses the sun’s position in the zodiac houses as a core label for personality. It is important to distinguish: astrological zodiac is not astronomical constellation. Due to precession (the slow wobble of Earth’s axis), the real astronomical positions of the Sun have shifted, and there is a 13th constellation Ophiuchus. However, astrological twelve houses follow ancient traditional divisions. They are a set of cultural symbolic systems, not conclusions from modern astronomical observation. To sum up: the twelve zodiac signs are cultural heritage from ancient civilisations, a set of symbolic tools rather than scientific facts.
