There are various myths associated to Aquila. The Greek mythology identifies Aquila as the eagle that carried Zeus’ thunderbolts and was once dispatched by the god to carry the young Trojan boy Ganymede whom Zeus desired, to Olympus to be the cup bearer of the gods. However, another story finds the eagle as guarding the arrow of Eros which hit Zeus and made him love–struck. Another myth states that Aquila represents Aphrodite disguised as an eagle, pretending to pursue Zeus in the form of a swan, so that Zeus’ love interest, the goddess Nemesis, would give him shelter.
