Origin of Constellations: In order to facilitate the study and observation of many stars in the sky, Mesopotamian astrologers divided the starry sky into several regions, and each region was a constellation.

So some people think that the practice of dividing the starry sky into constellations originated from Babylon and Sumer in Mesopotamia, and the constellations of Greece and Egypt may have been introduced from this area.

The ancient Greek poets Homer and hesiod also mentioned Ursa major, Orion and the Pleiades, while at the same time, Babylon recorded the zodiac in cuneiform.
