Aquila, the pet eagle of Zeus, showed the gentler side of his nature when he carefully carried up Ganymede to Mount Olympus to be cupbearer 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.
