“Transparent Forms, too fine for mortal Sight,
Their fluid Bodies half dissolv’d in Light.
Loose to the Wind their airy Garments flew,
Thin glitt’ring Textures of the filmy Dew;
Dipt in the richest Tincture of the Skies,
Where Light disports in ever-mingling Dies,
While ev’ry Beam new transient Colours flings,
Colours that change whene’er they wave their Wings.”

—Alexander Pope, The Rape Of The Lock, 1712.
