Our (modern) Explanation

Perseus, The Hero, is a constellation of the northern sky. Its Babylonian predecessor is an Old Man, a god of the earlier generation of gods, who walks after a plough. The old man walks bent forward so that his head is marked by bright stars, and the star cluster around alpha Persei marking the seeds that he carries (like van Gogh’s seeder) in front of his breast. The Greek reinterpretation of this image as Andromeda’s groom, a young man, leaves Perseus a bit headless among the stars. The ancient hero carries a metallic weapon against Cetus in his upper hand (marked by the double cluster h and chi Per) and the winged shoes of the god Hermes/ Mercury (wings marked by the silverfish glittering Pleiades).

The two men are connected at their feet. It appears as if they are fighting together, like athlets. This version of Perseus seems to depict the legendary companion of Erichthonios.

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.
