Myths and legends

In ancient Greek mythology, the favorite of Zeus, the king of gods, is neither Hera nor his incarnation. The Princess Europa who came to seduce the bull was actually a beautiful Cretan boy, Ganymede.

He turned into an eagle and kidnapped the beautiful boy, and made love with her openly on Mount Olympus, which aroused Hera's jealousy and designed to kill the beautiful boy and turn him into a Aquarius, Zeus was so sad that he sealed Ganymede's soul in the sky. This is the origin of Aquarius.
