1.  Greek goddess of the soul, symbolized by a butterfly. Her myth is that she was a mortal so beautiful that Aphrodite hated her and ordered Eros to make her fall in love with the most hideous man. But he loved her and whisked her away to his palace, ordering her to never look at his face. She eventually does and he abandons her. She searches the world for her lost love, and ends up serving Aphrodite who orders her to do a series of difficult tasks, including a trip to the Underworld. Eventually she is reunited with Eros and they are married with the gods attending. Psychologically her journey is symbolic of the individual’s path to wholeness.
