Our (modern) Explanation

Greek mythographers, namely Eratosthenes (and if you want also Roman Hyginus) give rather explicitly one story which identifies this specific arrow as the one on which riding Apollo and his sister Demeter (the god of light and the goddess of fertility) return to Greece in spring time – in winter they had been in a country far away called Hyperborea and which is considered at the Eastern edge of the world.

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.
