Psyche was happy until her sisters persuaded her to look at Cupid. As soon as Psyche looked at Cupid, Cupid punished her by leaving her. Their lovely castle and gardens vanished too. Psyche found herself alone in an open field with no signs of other beings or Cupid.
As she wandered trying to find her love, she came upon the temple of Venus. Wishing to destroy her, the goddess of love gave Psyche a series of tasks, each harder and more dangerous then the last.
For her last task Psyche was given a little box and told to take it to the underworld. She was told to get some of the beauty of Proserpine, the wife of Pluto, and put it in the box. During her trip she was given tips on avoiding the dangers of the realm of the dead. She was also warned not to open the box. But temptation overcame Psyche and she opened the box.
