only half of it is depicted. Aratus: it is the horse that caused a spring on the mountain Helicon. Others say, it is Pegasus after the fall of Bellerophon which is not believed by people who point out that there are no wings. Euripides says, it is Hippe, the daughter of the centaur Cheiron who was pregnant from Aiolos and hided from her father.

Early Modern Interpretation


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.
