There was a king with three beautiful daughters. Psyche, the youngest, was the most beautiful. Aphrodite, the goddess of love and beauty, grew jealous of Psyche's beauty. She asked her son, Eros, to cause Psyche to fall in love with a most atrocious monster. However, upon contemplating her beauty, Eros dropped the arrow destined for her, and fell in love with Psyche.
Psyche's parents consulted an oracle. They were told that she was destined to marry a monster. They were to take her to the top of a mountain, and leave her there. There, the west wind took her to a palace where she was waited on by invisible servants. Her husband would visit her by night, and told her that she must never try to see him.
Eventually, Psyche grew homesick. She implored her husband to allow her sisters to visit. The two elder sisters became jealous, and convinced Psyche to peer at her husband. They told her that he was a monster, and that her only chance at safety was to kill him. She took a lamp and a knife, but dripped some hot wax onto her husband's shoulder when she looked upon his beautiful face. Her husband was Eros. The wax woke him. When he met eyes with his wife, he disappeared.
Psyche roamed, searching for her husband. Unable to find him, she asked his mother, Aphrodite. Still angry and jealous, Aphrodite set various tasks for Psyche. With the help of the river gods, Psyche succeeded at her tasks. When Eros learned of his mother's treatment of Psyche, he begged Zeus to stop Aphrodite's persecution of Psyche, and they were married.
