The constellation that represents the eagle carrying Zeus’s thunderbolts is Aquila.
Aquila is Latin for “eagle” and lies on the celestial equator. In classical Greek mythology, it was identified with Aetos Dios, the eagle associated with Zeus. The bird carried the god’s thunderbolts and was also linked to the abduction of Ganymede, who became the cup-bearer of the Olympian gods.
Aquila was among the 48 constellations catalogued by the Greek astronomer Ptolemy in the 2nd century and remains one of the 88 modern constellations recognized by the International Astronomical Union. Its brightest star is Altair, one point of the prominent Summer Triangle.
A common mix-up is Aquarius: that constellation is often associated with Ganymede, the youth carried to Olympus, rather than with the eagle itself. Aquila is also sometimes connected with the eagle sent to torment Prometheus, so ancient sources do not give the bird only one mythological role.
