" Night fell, and her husband came to bed, and as soon as they had finished kissing and embracing each other, he fell fast asleep. Psyche was not naturally either very strong or very brave, but the cruel power of fate made a virago of her. Holding the carving knife in a murderous grip, she uncovered the lamp and let its light shine on the bed.

At once the secret was revealed. There lay the gentlest and sweetest of all wild creatures, Cupid himself, the beautiful Love-god, and at sight of him the flame of the lamp spurted joyfully up and the knife turned its edge for shame.

Psyche was terrified. She lost all control of her senses, and pale as death, fell trembling to her knees, where she desperately tried to hide the knife by plunging it in her own heart. She would have succeeded, too, had the knife not shrunk from the crime and twisted itself out of her hand. "
