Mythology of the constellation Aquila
Aquila, the pet eagle of Zeus, showed the gentler side of his nature when he carefully carried up Ganymede to Mount Olympus to be cup-bearer to his master. However, when considering the myth surrounding Prometheus, the ferocious, darker side of Aquila is very evident. Prometheus was one of the last Titan gods who became an advisor to Zeus. He was protective of humankind and, seeing how they suffered because they had no fire, he stole a ray from the Sun which he smuggled down to earth in a hollow stem.
Zeus did not believe that man was worthy of such a gift, and was furious that Prometheus had acted without his permission. The well-meaning Titan was chained to the side of a mountain, stripped of his garments, and was continually attacked by Aquila. Since he was immortal, his dreadful wounds healed themselves every evening, only to be opened up again the next day by Aquila.
After many years Prometheus was saved by Hercules, who agreed with his kind deed to mankind. Using his bow and arrow, he killed Aquila, who was then placed by Zeus to soar in the heavens.
