There are fifteen visual moments shown in the Fitzwilliam panel:


Jacopo del Sellaio, c.1442 – 1493; Cupid and Psyche panel 1, c.1473

M1: The sun god Apollo visits Endelechia in her bedchamber one night and impregnates her.

M2: A child is born, Psyche, who is brought up in the palace, tended by her 2 older sisters.

M3: She grows up into a girl of outstanding beauty and is admired by many suiters.

M4: Venus, the goddess of love, grows jealous at the honours paid to Psyche. She therefore sends her son Cupid to instill in Psyche an irresistible love for an ugly, worthless creature. But Cupid on catching sight of the girl is himself smitten.

M5: Meanwhile, although universally admired, Psyche’s extreme beauty intimidates suitors and in a bid to see how they can find her a husband, her parents take her to consult the oracle of Apollo – her true father.

M6: The oracle says that Psyche is to be left on a mountain top where she will not meet her predestined husband – a divine but monstrous creature. Psyche is therefore dispatched to the mountain top.

M7: At the summit she is blown upon by Zephyr, the west wind.

M8: She floats down into a valley.

M9: There she falls asleep on a bed of flowers.

M10: On waking she sees the palace of Cupid and goes in.

M11: Psyche is welcomed in the palace by invisible maids and sleeps with her new spouse, but is never allowed to set eyes upon him. This prohibition is essential for the story to continue as it does, but Sellaio unexpectedly includes a scene of Psyche standing before Cupid pleading with him to allow her sisters to visit.

M12:  Her sisters do visit. They jealously persuade her to break her vow and take a look at her husband as she sleeps, convincing her that he must be the monster prophesied by Apollo.

M13: The sisters leave the palace, carrying gifts.

M14: At night Psyche lights a lamp and gazing upon her sleeping husband, is struck by his beauty.

M15: A spit of oil from the lamp wakes Cupid & he flies away. Psyche tries to stop him by clinging onto his leg.



The story continues on the next panel.
