The origin of constellations

The knowledge of constellations originated from Babylon, one of the four ancient civilizations. At that time, they divided the sky into many areas and called them "constellations". However, the birthday that westerners usually say is the solar calendar (new calendar), so the constellations are calculated according to the solar calendar.

Babylonians made a long-term prediction of these constellations, determined the ecliptic through observation, and divided it into 12 equal parts, which is the "zodiac". According to the counterclockwise direction, they are Aries (Aries), Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius (Sagittarius), Capricorn, Aquarius (Aquarius) and Pisces.
