Our (modern) Explanation

The ancient Greek constellation of The Scorpion was imagined related to the death of the hunter Orion, but the Babylonian original showed a gigantic scorpion as a gate-keeper to the Netherworld. It marks the point when the Sun changed from the Northern to the Southern hemisphere (equinox) and was incorporated in the 4000 years old Epic of Gilgamesh.

Early Modern Interpretation

Contemporary

As one of their first tasks in the 1920s, the newly founded International Astronomical Union (IAU) established constellation standards. The Belgian astronomer Eugène Delporte was assigned to the task to define borders of constellations parallel to lines of declination and right ascension. They were accepted by the General Assembly in 1928. The standardized names and abbreviations had already been accepted in 1922 and 1925.
