From Anu Garg’s A.Word.A.Day, it’s iridescent:
PRONUNCIATION:Iridescent brings to my mind two bits of poetry. One is the first lines of Stanley Lombardo’s translation of Sappho’s appeal to Aphrodite:
(ir-i-DES-uhnt)
MEANING:
adjective: Displaying a rainbow of colors that change when seen from different angles.
ETYMOLOGY:
From Latin irido- (rainbow), from iris (rainbow, iris plant, diaphragm of the eye), from Greek iris. Iris was the goddess of rainbows in Greek mythology. Earliest documented use: 1794.
Shimmering,Note how iridescent echoes shimmering and deathless echoes iridescent. You can read the poem and an explanation of the translation at Jacket.
iridescent,
deathless Aphrodite
Iridescent for me also means a sentence in Marianne Moore’s “The Mind Is an Enchanting Thing”:
It’s fire in the dove-neck’sDove-neck’s, iridescence, in the inconsistencies, of (rhyming with dove), Scarlatti: ah! music. You can read the poem on the fly at Google Books.
iridescence; in the
inconsistencies
of Scarlatti.
