The nine Muses in Greek Mythology, the daughters of Zeus and Titan, were goddesses representing the arts—dance, music, and poetry—and also history, comedy, tragedy, and astronomy. Interestingly, there was no Muse for a visual art, for sculpture or painting.
Since those ancient times, muses began assuming human (mostly female) forms, and painters and photographers made up for any earlier absence of goddesses. An article in Flavorwire, The 10 Most Influential Artist’s Muses, describes several famous artist/muse combinations.
When I’m photographing, I’ve learned that a muse will remain invisible while asserting itself through seemingly disparate subjects, like the daylily and door shown here. And though I can’t explain this—it’s truly a feeling—I don’t doubt it for a second.
You should treat a muse like a fairy.
