But having got so far successfully through her dangerous task, a longing desire seized her to examine the contents of the box. “What,” said she, “shall I, the carrier of this divine beauty, not take the least bit to put on my cheeks to appear to more advantage in the eyes of my beloved husband!” So she carefully opened the box, but found nothing there of any beauty at all, but an infernal and truly Stygian sleep, which being thus set free from its prison, took possession of her, and she fell down in the midst of the road, a sleepy corpse without sense or motion.

But Cupid, being now recovered from his wound, and not able longer to bear the absence of his beloved Psyche, slipping through the smallest crack of the window of his chamber which happened to be left open, flew to the spot where Psyche lay, and gathering up the sleep from her body closed it again in the box, and waked Psyche with a light touch of one of his arrows. “Again,” said he, “hast thou almost perished by the same curiosity. But now perform exactly the task imposed on you by my mother, and I will take care of the rest.”

Then Cupid, as swift as lightning penetrating the heights of heaven, presented himself before Jupiter with his supplication. Jupiter lent a favoring ear, and pleaded the cause of the lovers so earnestly with Venus that he won her consent. On this he sent Mercury to bring Psyche up to the heavenly assembly, and when she arrived, handing her a cup of ambrosia, he said, “Drink this, Psyche, and be immortal; nor shall Cupid ever break away from the knot in which he is tied, but these nuptials shall be perpetual.”

Thus Psyche became at last united to Cupid, and in due time they had a daughter born to them whose name was Pleasure.

Bulfinch's Mythology — Part 72

The fable of Cupid and Psyche is usually considered allegorical. The Greek name for a _butterfly_ is Psyche, and the same word means the _soul_. There is no illustration of the immortality of the soul so striking and beautiful as the butterfly, bursting on brilliant wings from the tomb in which it has lain, after a dull, grovelling, caterpillar existence, to flutter in the blaze of day and feed on the most fragrant and delicate productions of the spring. Psyche, then, is the human soul, which is purified by sufferings and misfortunes, and is thus prepared for the enjoyment of true and pure happiness.
